INTRODUCTION

[003] Patients concurrently taking multiple medications, including prescription and nonprescription drugs, are at greatest risk of polypharmacy consequences. Although polypharmacy may be widespread throughout the general population, it is most common in people with multiple medical conditions. Such patients include the elderly, psychiatric patients, patients multiple drugs concurrently, those with multiple physicians and pharmacies, recently hospitalized patients, individuals with concurrent comorbidities, and those with impaired vision or dexterity, to mention a few.

[004] Polypharmacy generally refers to the use of multiple medications by a patient under various circumstances. Sometimes patients use too many forms of medication. Other times, more drugs are prescribed than is clinically warranted. And sometimes, even when all prescribed medications are clinically indicated, there may be too many pills to take for the patient to take. Polypharmacy generally results in increased adverse drug reactions, drug-drug interactions, and higher costs, among other deleterious effects caused by polypharmacy.

[005] To address various issues associated with polypharmacy, there is a need to custom-package individual medication dosing units for patients that take multiple medications or a regular basis. There also is a need to track the custom-package individual medication dosing units from the pharmacy to the patient and record the time when the package is opened and the medication dosing event occurs.

SUMMARY

[006] In one aspect, a custom medication dosing unit is provided. The custom medication dosing unit comprises a housing comprising at least one shell element provided with a generally bottom surface and a circumferential edge extending upwardly from the bottom surface and a portion defining an opening for accommodating at least one medication. A first closure element is provided with a circumferential edge placed on the circumferential edge of the shell element in an adhering and closing manner. At least one medication may be disposed within the opening defined between the portion of the shell element and the first closure element. A circuit module is associated within the first closure element.

The housing 105 including the compartments 1 16 and the closure elements 1 18 may be formed of a variety of polymers, metals, or combinations thereof, and in one aspect the housing 105 and the closure elements 1 14 may be formed of a polymer. The closure elements 1 14 may be configured to be opened in a relatively easy operation and in one aspect may be opened in a single rotatable operation by the user. It will be appreciated that other form factors are contemplated to be within the scope of the present disclosure, but are not shown for clarity of disclosure. For example, dual morning/afternoon (am/pm) medication dosing packages, as well as other custom packages such as a blister pack form factor are within the scope of the present of the disclosure.

[042] As previously mentioned, in one aspect the, the multi-dose package 104 may comprise a plurality of compartments 124 for storing a plurality of lEM devices 130. As shown, the lEM compartments 124 comprise a well 128 for accommodating an ingestible device, such as a single lEM device 130, as shown, for example. The lEM compartment 124 includes a closure element 126, shown partially opened, to protect the lEM device 130 from environmental factors such as moisture and light and also provides security before usage. In one aspect, the additional lEM compartments 124 are blister packs where the closure elements 126 are formed of a thin aluminum sheet such that the lEM device 130 can be pushed therethrough for access by the patient. Although the multi- dose package 104 is shown in a weekly dosage configuration, other configurations such as semi-daily (am/pm), monthly dosage, are contemplated within the scope of the present disclosure.

[043] In one aspect, the multi-dose unit 104 can be pre-packaged and customized for an individual patient by a physician, pharmacy, drug manufacturer, third party, or combinations thereof. The multi-dose package 104 contains one week's worth of individualized daily medication doses specifically customized for the patient. In one aspect, the closure element 1 18, or portions of the housing 105 (e.g., sidewalls or bottom portion), may be used to mark the multi-dose unit 104 with customized information associated with the individual patient. The customized information may include, without limitation, the name of the patient, the packaging date, the dosing event (e.g., morning, evening, daily), and the contents of the package, such as the identity of the medication(s) 122 contained inside each of the compartments 1 16, for example. As shown, the individual compartments 1 16 of the multi-dose package 104 are marked with the day of the week (e.g., M, Tu, W, Th, F, Sa, Su) in which the patient is to consume the dosing event contained within the central portion 120. In some aspects, the expiration date or shelf life of the one or more medication(s) 122 may be indicated on an exterior portion of the closure element 1 18, or exterior portions of the housing 105. In other aspects, the type of lEM device 130 contained in the multi-dose package 104 may be indicated on an exterior portion of the closure element 1 18, or exterior portions of the housing 105.

[044] In one aspect, the single-dose package 102 and the multi-dose package 104 may comprise electronic circuit module 1 15 integrated therewith, e.g., the housing 103 105 and/or the closure elements 1 14, 1 18. The single- and multi-dose packages 102, 104 may include any type of circuit module 1 15 configured to activate when the closure element 1 14 has been removed (e.g., by peeling or blistering), transmitting information associated with the single- and/or multi-dose packages 102, 104, and recording a time stamp associated with such event. In various aspects, a sensor element may be provided to detect the when the closure the closure element 1 14, 1 18 of the single- or multi-dose packages 102, 104 is removed from the corresponding shell element 103, 1 16.

[045] In certain aspects, an ingestible device, e.g., the lEM device 130 may be provided in the single- or multi-dose packages 102, 104 as part of the single medication dosing unit. When the lEM device is ingested and activated, the lEM device 130 may communicate with the external node 106 to confirm that the single- or multi-dose package 102, 104 was opened and that the lEM device 130 was ingested by the patient. Examples of an lEM are described in U.S. Patent Application Ser. No. 12/564,017, supra. In one example of the lEM. It will be appreciated that the lEM device130 is presumably ingested along with the other medication(s) 1 12, 122 provided inside the respective single- or multi-dose package 102, 104. Accordingly, the communication indicating that the lEM device 130 was ingested may be employed to confirm at least that the lEM device 130 was ingested and to infer that the other medication(s) 1 12, 122 also were consumed (e.g., ingested, inhaled, injected, absorbed) by the patient.

[046] In one aspect, an ingestible device, e.g., the lEM device 130, may communicate with the circuit module 1 15 before being ingested by the patient. This may be triggered by a timer mechanism or by a latching or locking mechanism provided on or in the single- or multi-dose packages 102, 104. In various aspects, this communication technique may be useful to confirm that the patient takes the ingestible device within a predetermined time period after opening the package or triggering an alarm. By way of example and not limitation, in one aspect, the ingestible device, e.g., the IEM device 130, may communicate to the circuit module 1 15, or the local node 106 directly, that the single- or multi-dose package 102, 104 has been opened. Once the "package open" signal is transmitted, a timer may be initiated. When the patient ingests the ingestible device, the ingestible device communicates to the local node 106 the ingestion event and the timer is reset. If the timer expires, an alarm indication is set. Accordingly, by monitoring the timer status, the local node 106 may provide a confirmation that the patient actually ingested the ingestible device after the single- or multi-dose package 102, 104 was opened. Other suitable techniques may be employed other then timers such as direct communication with the local node after the single- or multi-dose package 102, 104 is opened and after the ingestion event occurs to confirm the ingestion event.

[047] Turning now briefly to FIG. 8, in one aspect, the circuit module 1 15 may include a radio subsystem 800, a processing subsystem 802, a memory subsystem 804, and/or a power subsystem 806. In one aspect, the circuit module 1 15 comprises an optional power storage unit 808 (shown in phantom) to receive power from an external source and store the power in the power storage unit 808. The power storage unit 808 may comprise any suitable energy storage element such as a capacitor, supercapacitor, rechargeable battery cell (or multiple rechargeable battery cells), among other energy storage elements. In various aspects, the energy storage element of the power storage unit 808 may be charged via direct coupling, inductive coupling, electromagnetic coupling, eddy current, solar power, among other suitable energy coupling techniques. In one aspect, an inductive charging device, such as an inductive charging pad, may provide a wireless charging technique similar to that used for mid-sized items such as cell phones, MP3 players, personal; digital assistants (PDAs), tablet computers, and the like. In inductive charging, an adapter equipped with contact points may be attached to a back plate coupled to the power storage unit. When the power storage unit 808 requires a charge, it may be placed on a conductive charging pad. Once the contact points come in contact with the conductive surface of the charging pad, a small current moves through coils located in the charging pad, creating a small magnetic field which is gathered by the contact points of the adapter and converted into energy. The energy gathered is transferred to the rechargeable battery (capacitor or supercapacitor) of the power storage unit 808, as efficiently as if the device were connected to a wall socket with its regular wired adapter, for example.

[048] Turning back now to FIG. 1 , in one aspect, the electronic circuit module 1 15 integrated with the single- or multi-dose package 102, 104 may include a basic radio circuit including a transmitter, receiver, and/or transceiver to communicate information associated with the single- or multi-dose package 102, 104, such as opening the packages, purchasing, storing, and/or ingesting the IEM device 130. In certain aspects, the circuit module 1 15 may include other elements such as digital memory and a processor coupled thereto. The radio portion of the circuit module 1 15 is configured to communicate with the local node 106 and/or other nearby single- or multi-dose packages located in proximity to the single- or multi-dose package 102, 104 over the wireless media 144, 146. In various aspects, the circuit module 1 15 may be powered by an on-board battery or may be powered by a passive electromagnetic field in a manner similar to the way radio frequency identification (RFID) tags are powered using an external interrogation electromagnetic field without employing an on-board battery. In one aspect, any of the systems such as the patch 214, the mobile device 216, and/or the access point 208 may generate an external interrogation signal to power the circuit module 1 15.

[049] In various aspects, upon opening the closure element 1 14, 1 18, the radio of the circuit module 1 15 is activated and begins transmitting information to the local node 106 and/or to other single- or multi-dose package(s) 102, 104 over the wireless media 144, 146. The communication capabilities of the single-or multi-dose package 102, 104 provide integrity of supply chain, an interface for physicians such that the physician can select which medication doses (e.g., pills) go into the package, an interface for end users (e.g., patients or personal caregivers) to configure the types of medication doses or co-ingested IEM devices 130 to include in the single- or multi-dose package 102, 104. The information includes any information suitable for identifying the single- or multi-dose package 102, 104, the contents thereof, the source (e.g., physician, pharmacy, drug manufacturer, nutrition center), the end user or consumer (e.g., patient), and the like. The information may be transmitted using any suitable analog and/or digital technique. In various aspects, for example, the single- or multi-dose package 102, 104 may transmit information in the form of a packet, e.g., a formatted unit of data consisting of control information and user data (also known as payload). The control information provides data that the local node 106 needs to deliver the user data to the external node 108 such as source and destination addresses, error detection codes like checksums, and sequencing information. Typically, control information is found in packet headers and trailers, with user data in between. In other aspects, the information may be transmitted in a traditional point-to-point communication link to the local node 106 and may simply transmit data as a series of bytes, characters, or bits alone. In other aspects, the information may be transmitted using analog modulation and transmission techniques.

[050] The information transmitted by the circuit module 1 15 may comprise a series of digits representing a suitable identification number such as a serial number, for example, of the single- or multi-dose package 102, 104. In addition, the packet may include information associated with the type of package (single, multiple, morning, afternoon, evening, daily, weekly, monthly dosing event, and so on) the individual patient identification, the date of pre-packaging, the source, and the contents of the package, for example. In some aspects, the expiration date or shelf life of one or all of the medication(s) 1 12, 122 contained in the respective single- or multi-dose packages 102, 104 also may be transmitted by the single- or multi-dose packages 102, 104. The information may be communicated with encryption where a secret key may be provided by an entity associated with a remote node 108 such as a physician, pharmacy, drug manufacturer, nutrition center, for example. The IEM device130, as discussed in more detail hereinbelow, may be configured to be activated either upon opening the single- or multi-dose package 102, 104 or by ingestion by the patient, for example.

The servers also may be configured to provide responses directly to the subject, e.g., in the form of subject alerts, subject incentives, which are relayed to the subject via the communication device. The servers also may interact with a health care professional, e.g., RN, physician, which can use data processing algorithms to obtain measures of health and compliance of the subject, e.g., wellness index summaries, alerts, cross-patient benchmarks, and provide informed clinical communication and support back to the patient. The servers also may interact with pharmacies, nutrition centers, and drug manufactures.

[075] In one aspect, the remote node 108 may store in the database 142 the time and date stamp when the single- or double-dose 102, 104 packages are opened. In addition, when an IEM device 130 is provided in the dosing unit, the time and date stamp of when the IEM device 130 was ingested by the patient also may be stored in the database 142. In addition, an identification number such as a serial number, for example, identifying the single- or multi-dose packages 102, 104, the type of package (single, multiple, morning, afternoon, evening, daily, weekly, monthly dosing event, and so on) the individual patient identification, the date of pre-packaging, the source, and the contents of the package, for example, may be stored in the database 142. In some aspects, the expiration date or shelf life of one or all of the medication(s) 1 12, 122 contained in the respective single- or multi-dose packages 102, 104 also may be stored in the database 142. A specific implementation of the system 100 for tracking a polypharmacy custom medication dosing unit is described hereinbelow in connection with FIG. 2.

[076] FIG. 2 illustrates one aspect of a system 200 for tracking a polypharmacy custom medication dosing unit and recording a medication event associated therewith. For illustrative purposes, the system shows cross-sectional views of a single-dose package 102 in an open configuration 102-1 and a closed configuration 102-2. The single-dose package 102 comprises one or more medications 1 12 and in some aspects one or more IEM devices 206. The single-dose package 102 comprises a shell element 103 and a closure element 1 14. A circuit element 202 comprising an antenna 204 is associated (e.g., embedded) in the closure element 1 14. When the closure element 1 14 is in a closed configuration, the circuit element 202 is not activated. Although only the single- dose package 102 is disclosed in FIG. 2 for clarity of disclosure, the same principles apply to the multi-dose package 104 described with reference to FIG. 1 . Accordingly, the particular aspects of the polypharmacy custom medication dosing unit packages are not limited in the context of the aspects described with reference to FIG. 2.

[077] When the closure element 1 14 is peeled off, as shown by the single-dose package 102-1 , the circuit element 202 is activated and initiates a wireless transmission using the antenna 204 of the information associated with the single-dose package 102-1 . As previously discussed in connection with the description associated with FIG. 1 , the information comprises the single-dose package 102-1 identification number, patient identification information (e.g., name, address, phone number, email, social network web address), dosing unit 1 12 identification, IEM device 206 identification, time and date stamp when the single-dose package 102-1 was opened, time and date stamp when the IEM device was ingested by the patient and activated, among other information.

[078] In one aspect, the opened single-dose package 102-1 communicates with a local wireless access point 208 (e.g., Wi-Fi), which is coupled to a local area network 210 (LAN). The LAN 210 is coupled to a wide area network such as Internet 224, which is coupled to the remote node 108. Accordingly, upon opening the closure element 1 14 the single-dose package 102-1 is able to communicate information to the remote node 108 via the access point 208, the LAN 210 to hop on the Internet 224, and to the processing system 140 at the remote node 108 receives the information and stores it for processing by the database 142. The remote node 108 can access other networks 225 for processing the information received from the single-dose package 102-2.

[079] In another aspect, the opened single-dose package 102-1 communicates with a one or more mobile devices 216. The mobile devices 216 may be a handheld portable device, mobile telephone, smartphone, tablet personal computer (PC), or any combination thereof, configured to communicate over a wireless cellular network. The mobile device 216 receives the transmission from the opened single-dose package 102- 1 . The mobile device 216 communicates with a cell tower 218 and base station 220 and can access the Internet 224 via the cellular network 222. Accordingly, information received from the opened single-dose package 102-2 can be communicated to the remote node 108 via the Internet 224. The processing system 140 at the remote node 108 receives the information and stores it for processing by the database 142. [080] In another aspect, when the patient 212 opens the single-dose package 102-1 and ingests an IEM device 206, the IEM device 206 communicates with a patch 214 which includes various electronic modules for receiving a unique signature from the ingested IEM device 206 and communicating with local nodes. It will be appreciated, that in various aspects, the patch 214 may be configured to communicate with the access point 208 as well as the mobile device(s) 216. It will also be appreciated that the IEM device 206 can communicate with any system, such as the access point 208 or the mobile device 216 prior to ingestion as well as while in the package. Thus the patch 214 can effectively communicate with the remote node 108 via the Internet 224 through the LAN 210 or the cellular network 222. Substantially concurrently with the ingestion of the IEM device 206, the opened single-dose package 102-1 also initiates communications with either the access point 208 or the mobile device(s) 216 to communicate the information associated with the single-dose package 102-1 to the remote node 108. Software application algorithms resident at any node along the communication path, e.g., another single- or multi-dose package 102-1 , the access point 208, the patch 214, the mobile device(s) 216, a server at the base station 220, a server at the cellular network 222, the processing system 140, can correlate the event of ingestion of the IEM device 206 with the patient consuming the other medication(s) 1 12 contained in the single-dose package 102-1 .

[081 ] In other aspects, the opened single-dose package 102-1 communicates with a one or more nearby opened or unopened single- or multi-dose packages 102-2. Thus each package can essentially function as a wireless node or relay station. In one aspect, when one package 102-1 is opened to take a first dose of medication(s) 1 12-1 , a signal may be transmitted to another package 102-2 which contains a second dose of medication(s) 1 12-2 to be consumed by the patient a predetermined later time of the day. For example, when the patient opens the morning (am) single-dose package 102-1 to take the morning dose of medication(s) 1 12-1 , a signal may be transmitted to the an afternoon single-dose package 102-2 to send a reminder in case the patient 212 to take the afternoon medication(s) 1 12-2. The signal may be detected by any local nodes such as the access point 208, the patch 214, or the mobile device(s) 216.

[082] FIG. 3 illustrates one aspect of a system 300 for packaging and tracking a polypharmacy custom medication dosing unit. The system 300 shown in FIG. 3 comprises a pharmacy 302 (or physician's office, drug manufacturer, or nutrition center), a consumer 322, such as a patient for which the polypharmacy custom medication dosing unit package 304 is produced for, and a remote server computer 324 located at a remote node as described in connection with FIGS. 1 and 2. With reference back to FIG. 3, the consumer 322 places a request for custom packaged dosing unit package 304 to the remote server computer 324. The remote server computer 324 receives the request from the consumer 322 and transmits a request to the pharmacy 302 to place an order for the polypharmacy custom medication dosing unit package 304 in accordance with the consumer's 322 instructions. The pharmacy 302 fills the order and delivers the custom packaged dosing event package 304 to the consumer 322. Upon receiving the package 304 the consumer 322 takes the medication(s) 1 12 an/or the IEM device 206 contained in the package 304 in accordance with specific instructions from the physician or pharmacy. When the consumer opens the closure element 1 14, the circuit element 202 initiates a wireless transmission via the antenna 204 to a local node, as discussed in connection with FIGS. 1 and 2. The dosing event is communicated to the remote server computer 324 via one or more wired and/or wireless networks where the information associated with the consumer, the package 304, and the date and time stamp of the dosing event, among others, are received by the processing system 326 and stored in a database 328. The processing system 326 monitors all such dosing events from one or more consumers 322. The processing system 326 may automatically determine when to place an order for a new supply of polypharmacy custom medication dosing unit package 304 with the pharmacy 302.

[083] It will be appreciated that the remote server computer 324 may be located at a physician's office, pharmacy, drug manufacturer, nutrition center, or other entity associated with the treatment and prescription of medication(s) 1 12 and IEM devices 206 to the consumer 322. In other aspects, the remote server computer 324 may be located in any location worldwide to serve the function of tracking the polypharmacy custom medication dosing unit package 304 consumed by the consumer 322, placing orders with the pharmacy 302, among other functions.

[084] The polypharmacy custom medication dosing unit package 304 may be produced by the pharmacy 302 or drug manufacturer, physician, nutrition center, or other entity that is qualified to dispense the medication(s) 1 12 and/or the IEM device 206 contained in the package 304. Once the pharmacy 302 receives the order for the polypharmacy custom medication dosing unit package 304, the process of producing such a package 304 may proceed manually, automatically, or a combination of both. As shown, the shell element 103 of the package102 moves along a computerized conveyer system 320 where the medications that comprise the polypharmacy custom medication dosing unit are dispensed into the shell element 103 from dispensers 306, 308, 310, 312, 314. Each of the dispensers 306, 308, 310, 312, 314 releasing a medication into the shell element 103 according to the order received from the remote server 324. Upon fulfilling the order for the polypharmacy custom medication dosing unit, a closure element comprising a circuit element 202 and antenna 204 is applied to the shell element 103 at station 316. A printer 318, or other marking mechanism, applies a custom marking on the exterior portion of the closure element to indicate, among other elements, the name of consumer 322, the medication(s) 1 12 content of the package 304, the IEM device 206 identification, a package 304 identification, date and time that package 304 was filled. Also, the circuit element 202 may be programmed with the information to transmit upon opening the closure element 1 14. Such information comprises information associated with the individual consumer (e.g., patient) and/or the medication(s) 1 12, the name of the consumer (e.g., patient), packaging date and time, dosing event (e.g., morning, evening, daily), contents of the package, expiration date, shelf life, type of IEM device 206 contained inside the package 304, for example.

[085] FIG. 4A illustrates one aspect of a single dosing unit customized package 102 for an individual patient where the single dosing unit comprising multiple medications 1 12. In the illustrated example, an IEM device 206 also is included in the package 1 14. The closure element 1 14 is shown partially removed from the shell element 103 for the purpose of showing the contents of the package 102. The exterior portion of the closure element 1 14 includes the custom printed markings include, without limitation, the name, address, and telephone number of the patient, the contents, the packaging date, and the expiration date.

[086] FIG. 4B is a partial cutaway view of the multiple medication single dosing unit package 102 shown in FIG. 4A illustrating a circuit element 202 embedded in the closure element 1 14 portion of the housing of the multiple medication single dosing unit package 102. In one aspect, the circuit element 202 comprises a radio circuit and wirelessly transmits information via the antenna 204 when the closure element 1 14 is peeled off the shell element 103 of the housing. In one aspect, the information transmitted by the circuit element 202 is preprogrammed and may be the same or analogous to the information marked on the exterior portion of the closure element 1 14. Although not shown for clarity of disclosure, the multi-dose package 104 shown in FIG. 1 , also comprises a similar circuit module 1 15 embedded in the individual closure element 1 18.

[087] FIG. 5A is a diagram illustrating a typical packet 500 of information communicated from an individual patient customized single-dose package. In one aspect, the packet 500 includes the patient's name, address and telephone number, the package identification, the contents of the package including IEM device identification is applicable, the dosing event (e.g., AM/PM), the date and time when the package was sealed, the date and time when the package was opened, and the expiration date of the contents of the package.

[088] FIG. 5B is a diagram illustrating a typical packet 550 of information communicated from an individual patient customized multi-dose package. In one aspect, the packet 550 includes the information included in the packet 500 shown in FIG. 5A and in addition includes the day of the week corresponding to the opened compartment from which the medication was taken.

[089] FIG. 6 is a block functional diagram of one aspect of an integrated circuit component of the patch 214 shown in FIG. 2. In FIG. 6, a patch 600 comprises an electrode input 610. Electrically coupled to the electrode input 610 are a transbody conductive communication module 620 and a physiological sensing module 630. In one aspect, the transbody conductive communication module 620 is implemented as a first, e.g., high, frequency (HF) signal chain and the physiological sensing module 630 is implemented as a second, e.g., low, frequency (LF) signal chain. Also shown are CMOS temperature sensing module 640 (for detecting ambient temperature) and a 3-axis accelerometer 650. The patch 600 also comprises a processing engine 660 (for example, a microcontroller and digital signal processor), a non-volatile memory 670 (for data storage), and a wireless communication module 680 (to receive data from and/or transmit data to another device, for example in a data download/upload action, respectively). In various aspects, the communication modules 620, 680 may comprise one or more transmitters/receivers ("transceiver") modules. As used herein, the term "transceiver" may be used in a very general sense to include a transmitter, a receiver, or a combination of both, without limitation. In one aspect, the transbody conductive communication module 620 is configured to communicate with the IEM device 206-1 (FIG. 2). In one aspect, the wireless communication module 680 may be configured to communicate with the wireless access point 208 (FIG. 2). In another aspect, the wireless communication module 680 may be configured to communicate with the opened single-dose package 102-1 (FIG. 2), or multi-dose package, for example. In yet another aspect, the wireless communication module 680 may be configured to communicate with the mobile devices 216 (FIG. 2).

[090] The sensors 616 typically contact the patient 212 (FIG. 2), e.g., are removably attached to the torso. In various aspects, the sensors 616 may be removably or permanently attached to the patch 600. For example, the sensors 616 may be removably connected to the patch 600 by snapping metal studs. The sensors 616 may comprise, for example, various devices capable of sensing or receiving the physiologic data. The types of sensors 616 include, for example, electrodes such as biocompatible electrodes. The sensors 616 may be configured, for example, as a pressure sensor, a motion sensor, an accelerometer, an electromyography (EMG) sensor, an IEM device 206 (FIG. 2), a biopotential sensor, an electrocardiogram sensor, a temperature sensor, a tactile event marker sensor, and an impedance sensor.

[091 ] The feedback module 618 may be implemented with software, hardware, circuitry, various devices, and combinations thereof. The function of the feedback module 618 is to provide communication with the patient 212 (FIG. 2) in a discreet, tactful, circumspect manner as described above. In various aspects the feedback module 618 may be implemented to communicate with the patient 212 using techniques that employ visual, audio, vibratory/tactile, olfactory, and taste.

[092] FIG. 7 shows one aspect of an ingestible event marker. In various aspects the IEM devices 130, 206 shown in FIGS. 1 and 2-4 may be implemented in accordance with the system 720 shown in Fig. 7. The system 720 can be used in association with any medication product, as mentioned above, to determine the origin of the medication and to confirm that at least one of the right type and the right dosage of medication was delivered to the patient and in some aspects to determine when a patient takes the medication product. The scope of the present disclosure, however, is not limited by the environment and the medication product that may be used with the system 720. For example, the system 720 may be activated either in wireless mode, in galvanic mode by placing the system 720 within a capsule and then placing the capsule within a conducting fluid, or a combination thereof, or exposing the system 720 to air. Once placed in a conducting fluid, for example, the capsule would dissolve over a period of time and release the system 720 into the conducting fluid. Thus, in one aspect, the capsule would contain the system 720 and no product. Such a capsule may then be used in any environment where a conducting fluid is present and with any product. For example, the capsule may be dropped into a container filled with jet fuel, salt water, tomato sauce, motor oil, or any similar product. Additionally, the capsule containing the system 720 may be ingested at the same time that any pharmaceutical product is ingested in order to record the occurrence of the event, such as when the product was taken.

[093] In the specific example of the system 720 combined with a medication or pharmaceutical product, as the product or pill is ingested, or exposed to air, the system 720 is activated in galvanic mode. This may be particularly useful when a caregiver or user wants to know if the seal of the ingestible device has been broken on the single- or multi-dose packages 102, 104 (FIGS. 1 -4), or if the ingestible device was exposed to air in certain climates, e.g., high humidity that may potentially degrade an ingestible device such as an IEM device 130 (FIG. 1 ), 206 (FIGS. 2-4). The system 720 controls conductance to produce a unique current signature that is detected by the patch 214 (FIG. 2), for example, thereby signifying that the pharmaceutical product has been taken. When activated in wireless mode, the system controls modulation of capacitive plates to produce a unique voltage signature associated with the system 720 that is detected.

[094] In one aspect, the system 720 includes a framework 722. The framework 722 is a chassis for the system 720 and multiple components are attached to, deposited upon, or secured to the framework 722. In this aspect of the system 720, a digestible material 724 is physically associated with the framework 722. The material 724 may be chemically deposited on, evaporated onto, secured to, or built-up on the framework all of which may be referred to herein as "deposit" with respect to the framework 722. The material 724 is deposited on one side of the framework 722. The materials of interest that can be used as material 724 include, but are not limited to: Cu, CuCI, or Cul. The material 724 is deposited by physical vapor deposition, electrodeposition, or plasma deposition, among other protocols. The material 724 may be from about 0.05 to about 500 μηι thick, such as from about 5 to about 100 μηι thick. The shape is controlled by shadow mask deposition, or photolithography and etching. Additionally, even though only one region is shown for depositing the material, each system 720 may contain two or more electrically unique regions where the material 724 may be deposited, as desired.

[095] At a different side, which is the opposite side as shown in Fig. 7, another digestible material 726 is deposited, such that the materials 724, 726 are dissimilar and insulated from each other. Although not shown, the different side selected may be the side next to the side selected for the material 724. The scope of the present disclosure is not limited by the side selected and the term "different side" can mean any of the multiple sides that are different from the first selected side. In various aspects, the dissimilar material may be located at different positions on a same side. Furthermore, although the shape of the system is shown as a square, the shape may be any geometrically suitable shape. The materials 724, 726 are selected such that they produce a voltage potential difference when the system 720 is in contact with conducting liquid, such as body fluids. The materials of interest for material 726 include, but are not limited to: Mg, Zn, or other electronegative metals. As indicated above with respect to the material 724, the material 726 may be chemically deposited on, evaporated onto, secured to, or built-up on the framework. Also, an adhesion layer may be necessary to help the material 726 (as well as material 724 when needed) to adhere to the framework 722. Typical adhesion layers for the material 726 are Ti, TiW, Cr or similar material. Anode material and the adhesion layer may be deposited by physical vapor deposition, electrodeposition or plasma deposition. The material 726 may be from about 0.05 to about 500 μηι thick, such as from about 5 to about 100 μηι thick. However, the scope of the present disclosure is not limited by the thickness of any of the materials nor by the type of process used to deposit or secure the materials to the framework 722.

[096] According to the disclosure set forth, the materials 724, 726 can be any pair of materials with different electrochemical potentials. Additionally, in the embodiments wherein the system 720 is used in-vivo, the materials 724, 726 may be vitamins that can be absorbed. More specifically, the materials 724, 726 can be made of any two materials appropriate for the environment in which the system 720 will be operating. For example, when used with an ingestible product, the materials 724, 726 are any pair of materials with different electrochemical potentials that are ingestible. An illustrative example includes the instance when the system 720 is in contact with an ionic solution, such as stomach acids. Suitable materials are not restricted to metals, and in certain embodiments the paired materials are chosen from metals and non-metals, e.g., a pair made up of a metal (such as Mg) and a salt (such as CuCI or Cul). With respect to the active electrode materials, any pairing of substances-metals, salts, or intercalation compounds-with suitably different electrochemical potentials (voltage) and low interfacial resistance are suitable.

[097] Materials and pairings of interest include, but are not limited to, those reported in TABLE 1 below. In one embodiment, one or both of the metals may be doped with a non-metal, e.g., to enhance the voltage potential created between the materials as they come into contact with a conducting liquid. Non-metals that may be used as doping agents in certain embodiments include, but are not limited to: sulfur, iodine, and the like. In another embodiment, the materials are copper iodine (Cul) as the anode and magnesium (Mg) as the cathode. Aspects of the present disclosure use electrode materials that are not harmful to the human body.

[098] Thus, when the system 720 is in contact with the conducting fluid, a current path is formed through the conducting fluid between the dissimilar materials 724, 726. A control device 728 is secured to the framework 722 and electrically coupled to the materials 724, 726. The control device 728 includes electronic circuitry, for example control logic that is capable of controlling and altering the conductance between the materials 724, 726.

[099] The voltage potential created between the dissimilar materials 724, 726 provides the power for operating the system as well as produces the current flow through the conducting fluid and the system 720. In one aspect, the system 720 operates in direct current mode. In an alternative aspect, the system 720 controls the direction of the current so that the direction of current is reversed in a cyclic manner, similar to alternating current. As the system reaches the conducting fluid or the electrolyte, where the fluid or electrolyte component is provided by a physiological fluid, e.g., stomach acid, the path for current flow between the dissimilar materials 724, 726 is completed external to the system 720; the current path through the system 720 is controlled by the control device 728. Completion of the current path allows for the current to flow and in turn a receiver, not shown, can detect the presence of the current and recognize that the system 720 has been activated and the desired event is occurring or has occurred. Illustrative examples of receivers are shown in Figs. 12 through 17, as described hereinafter. Further examples of ingestible devices, including IEM devices, are shown in FIGS. 9 through 1 1 , as described hereinafter.

[0100] In one aspect, the two materials 724, 726 are similar in function to the two electrodes needed for a direct current power source, such as a battery. The conducting liquid acts as the electrolyte needed to complete the power source. The completed power source described is defined by the electrochemical reaction between the materials 724, 726 of the system 720 and enabled by the fluids of the body. The completed power source may be viewed as a power source that exploits electrochemical conduction in an ionic or a conducting solution such as gastric fluid, blood, or other bodily fluids and some tissues.

[0101 ] Additionally, the environment may be something other than a body and the liquid may be any conducting liquid. For example, the conducting fluid may be salt water or a metallic based paint.

[0102] In certain aspects, the two dissimilar materials 724, 726 are shielded from the surrounding environment by an additional layer of material. Accordingly, when the shield is dissolved and the two dissimilar materials 724, 726 are exposed to the target site, a voltage potential is generated.

[0103] In certain aspects, the complete power source or supply is one that is made up of active electrode materials, electrolytes, and inactive materials, such as current collectors, packaging. The active materials are any pair of materials with different electrochemical potentials. Suitable materials are not restricted to metals, and in certain embodiments the paired materials are chosen from metals and non-metals, e.g., a pair made up of a metal (such as Mg) and a salt (such as Cul). With respect to the active electrode materials, any pairing of substances-metals, salts, or intercalation compounds ~ with suitably different electrochemical potentials (voltage) and low interfacial resistance are suitable.

[0104] A variety of different materials may be employed as the materials that form the electrodes. In certain embodiments, electrode materials are chosen to provide for a voltage upon contact with the target physiological site, e.g., the stomach, sufficient to drive the system of the identifier. In certain embodiments, the voltage provided by the electrode materials upon contact of the metals of the power source with the target physiological site is 0.001 V or higher, including 0.01 V or higher, such as 0.1 V or higher, e.g., 0.3 V or higher, including 0.5 volts or higher, and including 1 .0 volts or higher, where in certain embodiments, the voltage ranges from about 0.001 to about 10 volts, such as from about 0.01 to about 10 V.

[0105] Referring still to Fig. 7, the dissimilar materials 724, 726 provide the voltage potential to activate the control device 728. Once the control device 728 is activated or powered up, the control device 728 can alter conductance between the first and second materials 724, 726 in a unique manner. By altering the conductance between the first and second materials 724, 726, the control device 728 is capable of controlling the magnitude of the current through the conducting liquid that surrounds the system 720. This produces a unique current signature that can be detected and measured by a receiver (not shown), which can be positioned internal or external to the body. Illustrative examples of receivers are shown in Figs. 12 through 17, as described hereinafter. Further, the receiver is disclosed in greater detail in US Patent Application Serial No. 12/673,326 entitled "BODY-ASSOCIATED RECEIVER AND METHOD" filed on December 15, 2009, and published as 2010-0312188 A1 dated December 09, 2010, which is incorporated herein by reference in its entirety. In addition to controlling the magnitude of the current path between the materials, non-conducting materials, membrane, or "skirt" are used to increase the "length" of the current path and, hence, act to boost the conductance path, as disclosed in the U.S. patent application Ser. No. 12/238,345 entitled, "IN-BODY DEVICE WITH VIRTUAL DIPOLE SIGNAL AMPLIFICATION" filed Sep. 25, 2008, and published as 2009-0082645 A1 dated March 26, 2009 the entire content of which is incorporated herein by reference. Alternatively, throughout the disclosure herein, the terms "non-conducting material," "membrane," and "skirt" are interchangeably used with the term "current path extender" without impacting the scope or the present embodiments and the claims herein. The skirt, shown in portion at 725, 727, respectively, may be associated with, e.g., secured to, the framework 722. Various shapes and configurations for the skirt are contemplated as within the scope of the various aspects of the present invention. For example, the system 720 may be surrounded entirely or partially by the skirt and the skirt maybe positioned along a central axis of the system 120 or off-center relative to a central axis. Thus, the scope of the present invention as claimed herein is not limited by the shape or size of the skirt. Furthermore, in other embodiments, the dissimilar materials 724, 726 may be separated by one skirt that is positioned in any defined region between the dissimilar materials 724, 726.

[0106] The system 720 may be grounded through a ground contact. The system 720 also may include a sensor module. In operation, ion or current paths are established between the first material 724 to the second material 726 and through a conducting fluid in contact with the system 720. The voltage potential created between the first and second materials 724, 726 is created through chemical reactions between the first and second materials 724, 726 and the conducting fluid. In one aspect, the surface of the first material 724 is not planar, but rather an irregular surface. The irregular surface increases the surface area of the material and, hence, the area that comes in contact with the conducting fluid.

[0107] In one aspect, at the surface of the first material 724, there is chemical reaction between the material 724 and the surrounding conducting fluid such that mass is released into the conducting fluid. The term mass as used herein refers to protons and neutrons that form a substance. One example includes the instant where the material is CuCI and when in contact with the conducting fluid, CuCI becomes Cu (solid) and CI- in solution. The flow of ions into the conduction fluid is via ion paths. In a similar manner, there is a chemical reaction between the second material 726 and the surrounding conducting fluid and ions are captured by the second material 726. The release of ions at the first material 724 and capture of ion by the second material 726 is collectively referred to as the ionic exchange. The rate of ionic exchange and, hence the ionic emission rate or flow, is controlled by the control device 728. The control device 728 can increase or decrease the rate of ion flow by altering the conductance, which alters the impedance, between the first and second materials 724, 726. Through controlling the ion exchange, the system 720 can encode information in the ionic exchange process. Thus, the system 720 uses ionic emission to encode information in the ionic exchange.

[0108] The control device 728 can vary the duration of a fixed ionic exchange rate or current flow magnitude while keeping the rate or magnitude near constant, similar to when the frequency is modulated and the amplitude is constant. Also, the control device 728 can vary the level of the ionic exchange rate or the magnitude of the current flow while keeping the duration near constant. Thus, using various combinations of changes in duration and altering the rate or magnitude, the control device 728 encodes information in the current flow or the ionic exchange. For example, the control device 728 may use, but is not limited to any of the following techniques namely, Binary Phase- Shift Keying (PSK), Frequency Modulation (FM), Amplitude Modulation (AM), On-Off Keying, and PSK with On-Off Keying.

[0109] Various aspects of the system 720 may comprise electronic components as part of the control device 728. Components that may be present include but are not limited to: logic and/or memory elements, an integrated circuit, an inductor, a resistor, and sensors for measuring various parameters. Each component may be secured to the framework and/or to another component. The components on the surface of the support may be laid out in any convenient configuration. Where two or more components are present on the surface of the solid support, interconnects may be provided.

[0110] The system 720 controls the conductance between the dissimilar materials and, hence, the rate of ionic exchange or the current flow. Through altering the conductance in a specific manner the system is capable of encoding information in the ionic exchange and the current signature. The ionic exchange or the current signature is used to uniquely identify the specific system. Additionally, the system 720 is capable of producing various different unique exchanges or signatures and, thus, provides additional information. For example, a second current signature based on a second conductance alteration pattern may be used to provide additional information, which information may be related to the physical environment. To further illustrate, a first current signature may be a very low current state that maintains an oscillator on the chip and a second current signature may be a current state at least a factor of ten higher than the current state associated with the first current signature.

[0111] Referring now to FIG. 9, in another aspect of an ingestible device is shown in more detail as system 2040. The system 2040 includes a framework 2042. In this aspect of the system 2040, a digestible or dissolvable material 2044 is deposited on a portion of one side of the framework 2042. At a different portion of the same side of the framework 2042, another digestible material 2046 is deposited, such that materials 2044 and 2046 are dissimilar. More specifically, material 2044 and 2046 are selected such that they form a voltage potential difference when in contact with a conducting liquid, such as body fluids. Thus, when the system 2040 is in contact with and/or partially in contact with the conducting liquid, then a current path, an example is shown in FIG. 10, is formed through the conducting liquid between material 2044 and 2046. A control device 2048 is secured to the framework 2042 and electrically coupled to the materials 2044 and 2046. The control device 2048 includes electronic circuitry that is capable of controlling part of the conductance path between the materials 2044 and 2046. The materials 2044 and 2046 are separated by a non-conducting skirt 2049. Various examples of the skirt 2049 are disclosed in U.S. Provisional Application No. 61/173,51 1 filed on Apr. 28, 2009 and entitled "HIGHLY RELIABLE INGESTIBLE EVENT MARKERS AND METHODS OF USING SAME" and U.S. Provisional Application No. 61 /173,564 filed on Apr. 28, 2009 and entitled "INGESTIBLE EVENT MARKERS HAVING SIGNAL AMPLIFIERS THAT COMPRISE AN ACTIVE AGENT"; as well as U.S. application Ser. No. 12/238,345 filed Sep. 25, 2008 and published as 2009-0082645, entitled "IN-BODY DEVICE WITH VIRTUAL DIPOLE SIGNAL AMPLIFICATION"; the entire disclosure of each is incorporated herein by reference.

[0112] Once the control device 2048 is activated or powered up, the control device 2048 can alter conductance between the materials 2044 and 2046. Thus, the control device 2048 is capable of controlling the magnitude of the current through the conducting liquid that surrounds the system 2040. As indicated above with respect to system 2030, a unique current signature that is associated with the system 2040 can be detected by a receiver (not shown) to mark the activation of the system 2040. In order to increase the "length" of the current path the size of the skirt 2049 is altered. The longer the current path, the easier it may be for the receiver to detect the current.

[0113] Referring now to FIG. 10, the system 2030 of FIG. 7 is shown in an activated state and in contact with conducting liquid. The system 2030 is grounded through ground contact 2052. The system 2030 also includes a sensor module 2074, which is described in greater detail with respect to FIG. 1 1 . Ion or current paths 2050 form between material 2034 to material 2036 through the conducting fluid in contact with the system 2030. The voltage potential created between the material 2034 and 2036 is created through chemical reactions between materials 2034/2036 and the conducting fluid.

[0114] FIG. 10A shows an exploded view of the surface of the material 2034. The surface of the material 2034 is not planar, but rather an irregular surface 2054 as shown. The irregular surface 2054 increases the surface area of the material and, hence, the area that comes in contact with the conducting fluid.

[0115] In one aspect, at the surface of the material 2034, there is chemical reaction between the material 2034 and the surrounding conducting fluid such that mass is released into the conducting fluid. The term "mass" as used herein refers to protons and neutrons that form a substance. One example includes the instant where the material is CuCI and when in contact with the conducting fluid, CuCI becomes Cu (solid) and CI. sup.- in solution. The flow of ions into the conduction fluid is depicted by the ion paths 2050. In a similar manner, there is a chemical reaction between the material 2036 and the surrounding conducting fluid and ions are captured by the material 2036. The release of ions at the material 2034 and capture of ion by the material 2036 is collectively referred to as the ionic exchange. The rate of ionic exchange and, hence the ionic emission rate or flow, is controlled by the control device 2038. The control device 2038 can increase or decrease the rate of ion flow by altering the conductance, which alters the impedance, between the materials 2034 and 2036. Through controlling the ion exchange, the system 2030 can encode information in the ionic exchange process. Thus, the system 2030 uses ionic emission to encode information in the ionic exchange.

[0116] The control device 2038 can vary the duration of a fixed ionic exchange rate or current flow magnitude while keeping the rate or magnitude near constant, similar to when the frequency is modulated and the amplitude is constant. Also, the control device 2038 can vary the level of the ionic exchange rate or the magnitude of the current flow while keeping the duration near constant. Thus, using various combinations of changes in duration and altering the rate or magnitude, the control device 2038 encodes information in the current flow or the ionic exchange. For example, the control device 2038 may use, but is not limited to any of the following techniques namely, Binary Phase-Shift Keying (PSK), Frequency modulation, Amplitude modulation, on-off keying, and PSK with on-off keying.

[0117] As indicated above, the various aspects disclosed herein, such as systems 720 and 2040 of FIGS. 7 and 9, respectively, include electronic components as part of the control device 2038 or the control device 2048. Components that may be present include but are not limited to: logic and/or memory elements, an integrated circuit, an inductor, a resistor, and sensors for measuring various parameters. Each component may be secured to the framework and/or to another component. The components on the surface of the support may be laid out in any convenient configuration. Where two or more components are present on the surface of the solid support, interconnects may be provided.

[0118] As indicated above, the system, such as system 2030 and 2040, control the conductance between the dissimilar materials and, hence, the rate of ionic exchange or the current flow. Through altering the conductance in a specific manner the system is capable of encoding information in the ionic exchange and the current signature. The ionic exchange or the current signature is used to uniquely identify the specific system. Additionally, the systems 2030 and 2040 are capable of producing various different unique exchanges or signatures and, thus, provide additional information. For example, a second current signature based on a second conductance alteration pattern may be used to provide additional information, which information may be related to the physical environment. To further illustrate, a first current signature may be a very low current state that maintains an oscillator on the chip and a second current signature may be a current state at least a factor of ten higher than the current state associated with the first current signature.

[0119] Referring now to FIG.1 1 , a block diagram representation of the control device 2038 is shown. The device 2030 includes a control module 2062, a counter or clock 2064, and a memory 2066. Additionally, the device 2038 is shown to include a sensor module 2072 as well as the sensor module 2074, which was referenced in FIG. 10. The control module 2062 has an input 2068 electrically coupled to the material 2034 and an output 2070 electrically coupled to the material 2036. The control module 2062, the clock 2064, the memory 2066, and the sensor modules 2072/2074 also have power inputs (some not shown). The power for each of these components is supplied by the voltage potential produced by the chemical reaction between materials 2034 and 2036 and the conducting fluid, when the system 2030 is in contact with the conducting fluid. The control module 2062 controls the conductance through logic that alters the overall impedance of the system 2030. The control module 2062 is electrically coupled to the clock 2064. The clock 2064 provides a clock cycle to the control module 2062. Based upon the programmed characteristics of the control module 2062, when a set number of clock cycles have passed, the control module 2062 alters the conductance characteristics between materials 2034 and 2036. This cycle is repeated and thereby the control device 2038 produces a unique current signature characteristic. The control module 2062 is also electrically coupled to the memory 2066. Both the clock 2064 and the memory 2066 are powered by the voltage potential created between the materials 2034 and 2036.

[0120] The control module 2062 is also electrically coupled to and in communication with the sensor modules 2072 and 2074. In the aspect shown, the sensor module 2072 is part of the control device 2038 and the sensor module 2074 is a separate component. In alternative aspects, either one of the sensor modules 2072 and 2074 can be used without the other and the scope of the present invention is not limited by the structural or functional location of the sensor modules 2072 or 2074. Additionally, any component of the system 2030 may be functionally or structurally moved, combined, or repositioned without limiting the scope of the present invention as claimed. Thus, it is possible to have one single structure, for example a processor, which is designed to perform the functions of all of the following modules: the control module 2062, the clock 2064, the memory 2066, and the sensor module 2072 or 2074. On the other hand, it is also within the scope of the present invention to have each of these functional components located in independent structures that are linked electrically and able to communicate.

[0121] Referring again to FIG. 1 1 , the sensor modules 2072 or 2074 can include any of the following sensors: temperature, pressure, pH level, and conductivity. In one aspect, the sensor modules 2072 or 2074 gather information from the environment and communicate the analog information to the control module 2062. The control module then converts the analog information to digital information and the digital information is encoded in the current flow or the rate of the transfer of mass that produces the ionic flow. In another aspect, the sensor modules 2072 or 2074 gather information from the environment and convert the analog information to digital information and then communicate the digital information to control module 2062. In the aspect shown in FIG.10, the sensor modules 2074 is shown as being electrically coupled to the material 2034 and 2036 as well as the control device 2038. In another aspect, as shown in FIG. 1 1 , the sensor module 2074 is electrically coupled to the control device 2038 at connection 2078. The connection 2078 acts as both a source for power supply to the sensor module 2074 and a communication channel between the sensor module 2074 and the control device 2038.

[0122] Referring now to FIG. 10B, the system 2030 includes a pH sensor module 2076 connected to a material 2039, which is selected in accordance with the specific type of sensing function being performed. The pH sensor module 2076 is also connected to the control device 2038. The material 2039 is electrically isolated from the material 2034 by a non-conductive barrier 2055. In one aspect, the material 2039 is platinum. In operation, the pH sensor module 2076 uses the voltage potential difference between the materials 2034/2036. The pH sensor module 2076 measures the voltage potential difference between the material 2034 and the material 2039 and records that value for later comparison. The pH sensor module 2076 also measures the voltage potential difference between the material 2039 and the material 2036 and records that value for later comparison. The pH sensor module 2076 calculates the pH level of the surrounding environment using the voltage potential values. The pH sensor module 2076 provides that information to the control device 2038. The control device 2038 varies the rate of the transfer of mass that produces the ionic transfer and the current flow to encode the information relevant to the pH level in the ionic transfer, which can be detected by a receiver (not shown). Thus, the system 2030 can determine and provide the information related to the pH level to a source external to the environment.

[0123] As indicated above, the control device 2038 can be programmed in advance to output a pre-defined current signature. In another aspect, the system can include a receiver system that can receive programming information when the system is activated. In another aspect, not shown, the switch 2064 and the memory 2066 can be combined into one device. [0124] In addition to the above components, the system 2030 may also include one or other electronic components. Electrical components of interest include, but are not limited to: additional logic and/or memory elements, e.g., in the form of an integrated circuit; a power regulation device, e.g., battery, fuel cell or capacitor; a sensor, a stimulator, etc.; a signal transmission element, e.g., in the form of an antenna, electrode, coil, etc.; a passive element, e.g., an inductor, resistor, etc.

[0125] For purposes of illustration, various receivers may be used with various aspects of the present invention. In one example of a receiver, sometimes referred to herein as a "signal receiver", two or more different demodulation protocols may be employed to decode a given received signal. In some instances, both a coherent demodulation protocol and a differential coherent demodulation protocol may be employed. FIG. 12 provides a functional block diagram of how a receiver may implement a coherent demodulation protocol, according to one aspect of the invention. It should be noted that only a portion of the receiver is shown in FIG. 12. FIG. 12 illustrates the process of mixing the signal down to baseband once the carrier frequency (and carrier signal mixed down to carrier offset) is determined. A carrier signal 2221 is mixed with a second carrier signal 2222 at mixer 2223. A narrow low-pass filter 2220 is applied of appropriate bandwidth to reduce the effect of out-of-bound noise. Demodulation occurs at functional blocks 2225 in accordance with the coherent demodulation scheme of the present invention. The unwrapped phase 2230 of the complex signal is determined. An optional third mixer stage, in which the phase evolution is used to estimate the frequency differential between the calculated and real carrier frequency can be applied. The structure of the packet is then leveraged to determine the beginning of the coding region of the BPSK signal at block 2240. Mainly, the presence of the sync header, which appears as an FM porch in the amplitude signal of the complex demodulated signal is used to determine the starting bounds of the packet. Once the starting point of the packet is determined the signal is rotated at block 2250 on the IQ plane and standard bit identification and eventually decoded at block 2260.

[0126] In addition to demodulation, the transbody communication module may include a forward error correction module, which module provides additional gain to combat interference from other unwanted signals and noise. Forward error correction functional modules of interest include those described in PCT Application Serial No. PCT/US2007/024225 and published as WO 2008/063626, the disclosure of which is herein incorporated by reference. In some instances, the forward error correction module may employ any convenient protocol, such as Reed-Solomon, Golay, Hamming, BCH, and Turbo protocols to identify and correct (within bounds) decoding errors.

[0127] In another example, the receiver includes a beacon module as shown in the functional block diagram of FIG. 13. The scheme outlined in FIG. 13 outlines one technique for identifying a valid beacon. The incoming signal 2360 represents the signals received by electrodes, bandpass filtered (such as from 10 KHz to 34 KHz) by a high frequency signaling chain (which encompasses the carrier frequency), and converted from analog to digital. The signal 2360 is then decimated at block 2361 and mixed at the nominal drive frequency (such as, 12.5 KHz, 20 KHz, etc.) at mixer 2362. The resulting signal is decimated at block 2364 and low-pass filtered (such as 5 KHz BW) at block 2365 to produce the carrier signal mixed down to carrier offset-signal 2369. Signal 2369 is further processed by blocks 2367 (fast Fourier transform and then detection of two strongest peaks) to provide the true carrier frequency signal 2368. This protocol allows for accurate determination of the carrier frequency of the transmitted beacon.

[0128] FIG. 14 provides a block functional diagram of an integrated circuit component of a signal receiver according to an aspect of the invention. In FIG. 14, receiver 2700 includes electrode input 2710. Electrically coupled to the electrode input 2710 are transbody conductive communication module 2720 and physiological sensing module 2730. In one aspect, transbody conductive communication module 2720 is implemented as a high frequency (HF) signal chain and physiological sensing module 2730 is implemented as a low frequency (LF) signal chain. Also shown are CMOS temperature sensing module 2740 (for detecting ambient temperature) and a 3-axis accelerometer 2750. Receiver 2700 also includes a processing engine 2760 (for example, a microcontroller and digital signal processor), non-volatile memory 2770 (for data storage) and wireless communication module 2780 (for data transmission to another device, for example in a data upload action).

[0129] FIG. 15 provides a more detailed block diagram of a circuit configured to implement the block functional diagram of the receiver depicted in FIG. 14, according to one aspect of the invention. In FIG. 15, receiver 2800 includes electrodes e1 , e2 and e3 (281 1 , 2812 and 2813) which, for example, receive the conductively transmitted signals by an IEM and/or sense physiological parameters or biomarkers of interest. The signals received by the electrodes 281 1 , 2812, and 2813 are multiplexed by multiplexer 2820 which is electrically coupled to the electrodes.

[0130] Multiplexer 2820 is electrically coupled to both high band pass filter 2830 and low band pass filter 2840. The high and low frequency signal chains provide for programmable gain to cover the desired level or range. In this specific aspect, high band pass filter 2830 passes frequencies in the 10 KHz to 34 KHz band while filtering out noise from out-of-band frequencies. This high frequency band may vary, and may include, for example, a range of 3 KHz to 300 KHz. The passing frequencies are then amplified by amplifier 2832 before being converted into a digital signal by converter 2834 for input into high power processor 2880 (shown as a DSP) which is electrically coupled to the high frequency signal chain.

[0131] Low band pass filter 2840 is shown passing lower frequencies in the range of 0.5 Hz to 150 Hz while filtering out out-of-band frequencies. The frequency band may vary, and may include, for example, frequencies less than 300 Hz, such as less than 200 Hz, including less than 150 Hz. The passing frequency signals are amplified by amplifier 2842. Also shown is accelerometer 2850 electrically coupled to second multiplexer 2860. Multiplexer 2860 multiplexes the signals from the accelerometer with the amplified signals from amplifier 2842. The multiplexed signals are then converted to digital signals by converter 2864 which is also electrically coupled to low power processor 2870.

[0132] In one aspect, a digital accelerometer (such as one manufactured by Analog Devices), may be implemented in place of accelerometer 2850. Various advantages may be achieved by using a digital accelerometer. For example, because the signals the digital accelerometer would produce signals already in digital format, the digital accelerometer could bypass converter 2864 and electrically couple to the low power microcontroller 2870-in which case multiplexer 2860 would no longer be required. Also, the digital signal may be configured to turn itself on when detecting motion, further conserving power. In addition, continuous step counting may be implemented. The digital accelerometer may include a FIFO buffer to help control the flow of data sent to the low power processor 2870. For instance, data may be buffered in the FIFO until full, at which time the processor may be triggered to turn awaken from an idle state and receive the data.

[0133] Low power processor 2870 may be, for example, an MSP430 microcontroller from Texas Instruments. Low power processor 2870 of receiver 2800 maintains the idle state, which as stated earlier, requires minimal current draw-e.g., 10 .mu.A or less, or 1 .mu.A or less.

[0134] High power processor 2880 may be, for example, a VC5509 digital signal process from Texas Instruments. The high power processor 2880 performs the signal processing actions during the active state. These actions, as stated earlier, require larger amounts of current than the idle state~e.g., currents of 30 .mu.A or more, such as 50 .mu.A or more-and may include, for example, actions such as scanning for conductively transmitted signals, processing conductively transmitted signals when received, obtaining and/or processing physiological data, etc.

[0135] Also shown in FIG. 15 is flash memory 2890 electrically coupled to high power processor 2880. In one aspect, flash memory 2890 may be electrically coupled to low power processor 2870, which may provide for better power efficiency.

[0136] Wireless communication element 2895 is shown electrically coupled to high power processor 2880 and may include, for example, a BLUETOOTH. TM. wireless communication transceiver. In one aspect, wireless communication element 2895 is electrically coupled to high power processor 2880. In another aspect, wireless communication element 2895 is electrically coupled to high power processor 2880 and low power processor 2870. Furthermore, wireless communication element 2895 may be implemented to have its own power supply so that it may be turned on and off independently from other components of the receiver~e.g., by a microprocessor.

[0137] With an idle state in mind, the following paragraphs provide example configurations of receiver components shown in FIG. 15 during various states of the receiver, according to one aspect of the invention. It should be understood that alternative configurations may be implemented depending on the desired application.

[0138] In an idle state, for example, the receiver draws minimal current. Receiver 2800 is configured such that low power processor 2870 is in an inactive state (such as idle state) and high power processor 2880 is in an inactive state (such as idle state), and circuit blocks related to peripheral circuitry and their power supplies required during various active states remain off (for example, wireless communication module 2895 and the analog front end). For example, the low power processor may have a 32 KHz oscillator active and may consume a few .mu.A current or less, including 0.5 .mu.A or less. In the idle state, the low power processor 2870 may, for example, wait for a signal to transfer to an active state. The signal might be external such as an interrupt or internally generated by one of the device's peripherals, such as a timer. During the high power processor's idle state, the high power processor may, for example, be running off a 32 KHz watch crystal. The high power processor may, for example, wait for a signal to transfer to active state.

[0139] When the receiver is in the sniff state, low power processor 2870 is in an idle state and high power processor 2880 is in an idle state. In addition, the circuit blocks relating to the analog front end including A/D converter that is needed for the sniff function are on (in other words, the high frequency signal chain). As stated earlier, the beacon signal module may implement various types of sniff signals to achieve low power efficiency.

[0140] Upon detection of a transmitted signal, a higher power demodulate and decode state may be entered. When the receiver is in the demodulate and decode state, low power processor 2870 is in an active state and high power processor 2880 is in an active state. High power processor 2880 may, for example, be running from a 12 MHz or near crystal oscillator with a PLL-based clock multiplier giving the device a 108 MHz clock speed. The low power processor 2870 may, for example, run off an internal R-C oscillator in the range of 1 MHz to 20 MHz and consume power in the range of 250 to 300 uA per MHz clock speed during active states. The active state allows for processing and any transmissions that may follow. Required transmissions may trigger the wireless communication module to cycle from off to on.

[0141] When the receiver is in collect ECG and accelerometer state, the circuit blocks relating to the accelerometer and/or ECG signal conditioning chain are on. The high power processor 2880 is in an in idle state during collection, and in an active state (for example, running from a 12 MHz or near crystal oscillator with a PLL-based clock multiplier giving the device a 1 08 MHz clock speed) during processing and transmission. The low power processor 2870 is in an active state during this state and may run off an internal R-C oscillator in the range of 1 MHz to 20 MHz and consume power in the range of 250 to 300 uA per MHz clock speed.

[0142] The low power processor (e.g., MSP shown in FIG. 15) and high power processor (e.g., DSP shown in FIG. 15) may communicate with each other using any convenient communication protocol. In some instances, these two elements, when present, communicate with each via a serial peripheral interface bus (hereinafter "SPI bus"). The following description describes the signaling and messaging scheme implemented to allow the high power processor and low power processor to communicate and send messages back and forth along the SPI bus. For the following description of the communication between the processors, "LPP" and "HPP" are used in place of "low power processor" and "high power processor", respectively, to stay consistent with FIG. 15. The discussion, however, may apply to other processors than those shown in FIG. 15.

[0143] FIG. 16 provides a view of a block diagram of hardware in a receiver according to an aspect of the invention related to the high frequency signal chain. In FIG. 16, receiver 2900 includes receiver probes (for example in the form of electrodes 291 1 , 2912 and 2913) electrically coupled to multiplexer 2920. Also shown are high pass filter 2930 and low pass filter 2940 to provide for a band pass filter which eliminates any out-of-band frequencies. In the aspect shown, a band pass of 10 KHz to 34 KHz is provided to pass carrier signals falling within the frequency band. Example carrier frequencies may include, but are not limited to, 12.5 KHz and 20 KHz. One or more carriers may be present. In addition, receiver 2900 includes analog to digital converter 2950-for example, sampling at 500 KHz. The digital signal can thereafter be processed by the DSP. Shown in this aspect is DMA to DSP unit 2960 which sends the digital signal to dedicated memory for the DSP. The direct memory access provides the benefit of allowing the rest of the DSP to remain in a low power mode.

[0144] An example of a system that includes a receiver is shown in FIG. 17. In FIG. 17, system 3500 includes a pharmaceutical composition 3510 that comprises an ingestible device such as an ingestible event marker, " IEM." Also present in system 3500 is signal receiver 3520 Signal receiver 3520 is configured to detect a signal emitted from the identifier of the IEM 3510. Signal receiver 3520 also includes physiologic sensing capability, such as ECG and movement sensing capability. Signal receiver 3520 is configured to transmit data to a patient's an external device or PDA 3530 (such as a smart phone or other wireless communication enabled device), which in turn transmits the data to a server 3540. Server 3540 may be configured as desired, e.g., to provide for patient directed permissions. For example, server 3540 may be configured to allow a family caregiver 3550 to participate in the patient's therapeutic regimen, e.g., via an interface (such as a web interface) that allows the family caregiver 3550 to monitor alerts and trends generated by the server 3540, and provide support back to the patient, as indicated by arrow 3560. The server 3540 may also be configured to provide responses directly to the patient, e.g., in the form of patient alerts, patient incentives, etc., as indicated by arrow 3565 which are relayed to the patient via PDA 3530. Server 3540 may also interact with a health care professional (e.g., RN, physician) 3555, which can use data processing algorithms to obtain measures of patient health and compliance, e.g., wellness index summaries, alerts, cross-patient benchmarks, etc., and provide informed clinical communication and support back to the patient, as indicated by arrow 3580.

[0145] It is worthy to note that any reference to "one aspect" or "an aspect" means that a particular feature, structure, or characteristic described in connection with the aspect is included in at least one aspect. Thus, appearances of the phrases "in one aspect" or "in an aspect" in various places throughout the specification are not necessarily all referring to the same aspect. Furthermore, the particular features, structures or characteristics may be combined in any suitable manner in one or more aspects.

[0146] Some aspects may be described using the expression "coupled" and "connected" along with their derivatives. It should be understood that these terms are not intended as synonyms for each other. For example, some aspects may be described using the term "connected" to indicate that two or more elements are in direct physical or electrical contact with each other. In another example, some aspects may be described using the term "coupled" to indicate that two or more elements are in direct physical or electrical contact. The term "coupled," however, also may mean that two or more elements are not in direct contact with each other, but yet still co-operate or interact with each other.
