[0045] For the sake of brevity, conventional components and techniques and other functional aspects of the systems (and the individual operating components of the systems) may not be described in detail herein. Furthermore, the connecting lines shown in the various figures contained herein are intended to represent example functional relationships and/or physical couplings between the various elements. Many alternative or additional functional relationships or physical connections may be present in an embodiment. [0046] The concepts described herein provide for a breast milk flow monitoring system that includes a milk flow monitoring sensor that is composed of one or a plurality of electrode pairs, or an electrode array, and a controller. The electrode pair(s) may communicate with the controller via a wiring harness that includes one or more cables. In some embodiments, the milk flow monitoring sensor also includes a temperature sensor and/or a movement sensor, e.g., an inertial monitoring unit (IMU) that incorporates one or multiple accelerometers. [0047] The breast milk flow monitoring system employs the controller and the milk flow monitoring sensor to measure the resistance between the electrodes that is due to tissue or subcutaneous fluid under the skin, mammary glands, and milk contained within employing bio-impedance spectroscopic analysis. Bio-impedance relates to a measure of resistance of living tissue in response to an externally applied electric current. [0048] As milk flows, is ejected, sucked or expressed out of the breast, bioimpedance values change in relation to fluid leaving the breast. Bioimpedance values can be calibrated to indicate fluid levels of milk in the breast, and the amount of milk that has left the breast via pumping or feeding by an infant, and also to indicate milk replenishment in the breast between feedings. [0049] Each electrode pair of the milk flow monitoring sensor has a first electrode for sending an excitation signal and a second electrode for receiving a current response signal. Each electrode array of the milk flow monitoring sensor has a first electrode for sending an excitation signal and one or multiple electrodes for receiving a current response signal. Each electrode includes an electrically conductive surface for contact with a skin surface of a breast. The controller is operative to generate the excitation signal, which is communicated via the first electrode to the breast. The excitation signal is calibrated for breast milk flow. The controller receives, via the second electrode, a current response signal in response to the excitation signal, and executes bio-impedance spectroscopic analysis using the excitation signal and the current response signal. The bio-impedance spectroscopic analysis is calibrated for breast milk flow. The controller determines a breast milk flow parameter based upon the bio-impedance spectroscopic analysis. [0050] The process of generating the excitation signal, receiving the current response signal, and executing the bio-impedance spectroscopic analysis may be repeated multiple times during an infant feeding event. [0051] The breast milk flow monitoring system may be activated by some form of triggering mechanism, including but not limited to pressing a button on the controller, or voice activation. [0052] The electrodes of the milk flow monitoring sensor may be embedded, adhered to, or otherwise physically attached to a holder that is formed from a material that has been molded in a shape to be fitted on and capable of direct contact with a portion of a surface of a breast, such as being positioned on a breast, onto a breast, attached to the breast, placed between the breast and a brassiere or bra, a breast shield, breast pump funnel, or otherwise operatively attached to the surface skin of the breast. The base material of the holder may be silicon or another inert, non-reactive material for placement on the skin. [0053] Referring now to the drawings, which are provided for the purpose of illustrating certain embodiments only and not for the purpose of limiting the same, FIG.1 schematically illustrates elements of a breast milk flow monitoring system 100 that includes a milk flow monitoring sensor 10 that is in communication with a controller 50 that is capable of processing signals from the milk flow monitoring sensor 10 and executing a bio-impedance spectroscopic analysis to determine a breast milk flow parameter. The controller 50 includes input/output and signal processing circuitry 52, a memory device 54 storing one or a plurality of executable algorithms, collected data and one or multiple calibrations, and a processor 56. [0054] Alternatively, or in addition, the breast milk flow monitoring system 100 may be calibrated to account for extracellular and intracellular fluid movement in the breast other than milk, which fluids may include water or blood, with such movement being associated with breast milk flow. [0055] The milk flow monitoring sensor 10 includes, in one embodiment, an array of sensors in the form of first and second electrode pairs 20, 30, respectively, which may be arranged on flexible substrates 24, 34, respectively, which may be placed in a conformable holder (not shown in FIG.1). As shown, the milk flow monitoring sensor 10 employs two electrode pairs 20, 30. Alternatively, the milk flow monitoring sensor 10 may employ a single electrode pair. Alternatively, the milk flow monitoring sensor 10 may employ three electrode pairs, four electrode pairs, five electrode pairs, etc., without limitation. Alternatively, the milk flow monitoring sensor 10 may employ three, four, five, six, etc. electrodes that are arranged singly. [0056] The first electrode pair 20 includes a first electrode 21 and a second electrode 22, and the second electrode pair 30 includes a third electrode 31 and a fourth electrode 32. [0057] The first electrode 21, second electrode 22, third electrode 31, and fourth electrode 32 are arranged to have direct contact with a skin surface of a lactating breast to maximize surface contact and maximize signal coupling and conductivity to the skin surface. The direct contact between the respective electrode and the proximal skin surface may be via a dry contact, or via an intervening conductive gel. [0058] The first electrode 21, second electrode 22, third electrode 31, and fourth electrode 32 are arranged to contact with, attach to, or otherwise interface with skin to send and/or receive electrical signals, and may be fabricated from stainless steel, silver, metal alloys, or other material without limitation. The first electrode 21, second electrode 22, third electrode 31, and fourth electrode 32 may be dry electrodes, wet electrodes, semi-dry electrodes, or combinations thereof. [0059] Each of the first electrode 21, second electrode 22, third electrode 31, and fourth electrode 32 is in communication with the controller 50. In one embodiment and as shown, the first electrode 21, second electrode 22, third electrode 31, and fourth electrode 32 communicate with the controller 50 via an electrical cable 15. Alternatively, one or more of the first electrode 21, second electrode 22, third electrode 31, and fourth electrode 32 may communicate wirelessly with the controller 50. [0060] The flexible substrate 24 includes the first electrode 21 and the third electrode 31, and the flexible substrate 34 includes the second electrode 22 and fourth electrode 32 in one embodiment. [0061] In one embodiment, the milk flow monitoring sensor 10 includes a temperature sensor 18 that is arranged on one of the flexible substrates 24, 34 to have direct contact with the skin surface of the lactating breast. [0062] In one embodiment, the milk flow monitoring sensor 10 includes a movement sensor 16. In one embodiment, the movement sensor 16 is an inertial measurement unit (IMU) including one or multiple accelerometers, which is arranged on one of the flexible substrates 24, 34 to have direct contact with the skin surface of the lactating breast. In one embodiment, a single movement sensor 16 may be employed. In one embodiment, a plurality of movement sensors 16 may be employed, wherein the plurality of movement sensors 16 are implemented adjacent to or integral to one of the first electrode 21, second electrode 22, third electrode 31, and fourth electrode 32. The movement sensor 16 may be a piezoelectric accelerometer, a piezoresistive film, or another motion sensing device capable of sensing vibration, movement artifacts, etc., without limitation. [0063] The movement sensor 16 monitors physical movement of the breast, which may be a movement artifact that is indicative of an infant nursing or of breast pumping. When a plurality of movement sensors 16 are employed, they may be arranged, configured, and/or calibrated to measure different movements. By way of a non-limiting example, a first of the plurality of movement sensors 16 may be arranged on the holder to monitor gross body movement of the nursing mother, a second of the plurality of movement sensors 16 may be arranged to monitor movement of the breast as a result of nursing, and other(s) of the plurality of movement sensors 16 may be arranged to monitor other vibrations and/or movements. [0064] The milk flow monitoring sensor 10 has minimal components, may be arranged to be non-intrusive to the nipple area of the breast and thus not interfere with a nursing infant. Positioning of the milk flow monitoring sensor 10 on a breast is flexible, thus being adaptable to a range of breast sizes and configurations. Furthermore, the milk flow monitoring sensor 10 may be used with a nipple shield or other devices. Example locations for positioning the milk flow monitoring sensor 10 are illustrated and described with reference to FIG.9. [0065] As described in more detail herein, the controller 50 includes algorithms, calibrations, and other signal processing capabilities to generate one or multiple excitation signals that are communicated to the first electrode 21 of the first electrode pair 20 and the third electrode 31 of the second electrode pair 30. The controller 50 receives one or multiple current response signal(s) via the second electrode 22 of the first electrode pair 20 and the fourth electrode 32 of the second electrode pair 30. In one embodiment, a first excitation signal that is communicated to the first electrode 21 of the first electrode pair 20 may occur simultaneously with a second excitation signal that is communicated to the third electrode 31 of the second electrode pair 30. Alternatively, the first excitation signal that is communicated to the first electrode 21 of the first electrode pair 20 may alternate with the second excitation signal that is communicated to the third electrode 31 of the second electrode pair 30 in one embodiment. [0066] In one embodiment, the controller 50 is operative to generate a first excitation signal that is communicated via the first electrode 21 to a first location on the breast, wherein the first excitation signal is calibrated for breast milk flow. The controller 50 receives, via one or more of the second electrode 22, the third electrode 31, and the fourth electrode 32, a first current response signal in response to the first excitation signal. [0067] The controller 50 subsequently generates a second excitation signal that is communicated via the first electrode 21 to the first location on the breast, wherein the second excitation signal is also calibrated for breast milk flow. The controller 50 receives, via one or more of the second electrode 22, the third electrode 31, and the fourth electrode 32, a second current response signal in response to the first excitation signal. [0068] In one embodiment, the first excitation signal is a low frequency excitation signal, and the second excitation signal is a high frequency excitation signal. In one embodiment, the low frequency excitation signal is a single frequency sine wave having a frequency of less than 50 kHz, and the high frequency excitation signal is a single frequency sine wave having a frequency between 50 kHz and 1000 kHz. Alternatively, the first excitation signal is a broad spectrum sine wave encompassing a low frequency range, and the second excitation signal is a broad spectrum sine wave encompassing a high frequency range. [0069] The controller 50 executes a bio-impedance spectroscopic analysis of the first excitation signal, the second excitation signal, the first current response signal, and the second current response signal, wherein the bio-impedance spectroscopic analysis is calibrated for breast milk flow to determine a breast milk flow parameter. In one embodiment, this includes the controller 50 determining a ratio of the first current response signal and the second current response signal, and executing a bio-impedance spectroscopic analysis of the ratio of the first current response signal and the second current response signal, wherein the bio-impedance spectroscopic analysis is calibrated for breast milk flow to determine a breast milk flow parameter. [0070] The bio-impedance spectroscopic analysis of the ratio of the first current response signal and the second current response signal may include determining a parameter associated with at least one of an impedance (z), a reactance (Xc), a resistance (R), and a phase (Ph) based upon the bio-impedance spectroscopic analysis of the ratio of the first current response signal and the second current response signal, and determining the breast milk flow parameter based upon the least one of the impedance (z), the reactance (Xc), the resistance (R), and the phase (Ph). [0071] In one embodiment, the first excitation signal that is communicated to the first electrode 21 of the first electrode pair 20 may be in the form of a low frequency sinusoidal wave form that lasts less than 100 ms, wherein the low frequency waveform is less than 50 kHz. In one embodiment, the second excitation signal that is communicated to the second electrode 31 of the second electrode pair 30 may be in the form of a high frequency sinusoidal wave form that lasts less than 100 ms, wherein the high frequency waveform is between 50 kHz and 1000 kHz. [0072] The first and second current response signals that are received via the second electrode 22, third electrode 31 and the fourth electric 32 represent electrical current(s) that has passed through the intervening breast tissue and skin tissue and originates from the first electrode. A temperature input from the temperature sensor 18 and a parameter associated with physical movement of the breast are also monitored, when available. [0073] The controller 50 executes a bio-impedance spectroscopic analysis of the excitation signal(s) and the current response signal(s), wherein the bio-impedance spectroscopic analysis is calibrated for breast milk flow. The bio impedance spectroscopic analysis calibrated for breast milk flow may include measuring the electrical current passing through the breast tissue at various frequencies of the excitation voltage in a form of electrical cell-substrate impedance sensing (ECIS), in one embodiment. The controller 50 then determines a breast milk flow parameter based upon the bio-impedance spectroscopic analysis. This operation may be executed multiple times during a single breastfeeding event. [0074] FIGS.2 and 3 pictorially show elements of an embodiment of the milk flow monitoring sensor 210 including at least one electrode pair 220 and controller 250, and is analogous to the milk flow monitoring sensor 10 that is described with reference to FIG.1. In one embodiment, the milk flow monitoring sensor 210 may include a temperature sensor 218 and/or one or a plurality of movement sensors 216 in one embodiment. Alternatively, or in addition, the milk flow monitoring sensor 210 may include one or a plurality of strain gages. [0075] The milk flow monitoring sensor 210 is affixed to an article of wearable clothing, e.g., a nursing bra 200 in one embodiment. A nursing infant 224 is also illustrated. The nursing bra 200 includes a cradle portion 236 that supports cups 230 that are composed of cup frames 232 and detachable panels 234. The milk flow monitoring sensor 210 is affixed to each of the cup frames 232 at defined locations to facilitate placement of the electrode pair(s) 221, 222 so that they have direct physical contact with skin of a breast 240. The controller 250 is attachable to the cradle portion 236. The milk flow monitoring sensor 210 and controller 250 are detachable to facilitate laundering of the nursing bra 200. As illustrated, the milk flow monitoring sensor 210 is affixed to a right side of the nursing bra 200 for monitoring a right breast. A second milk flow monitoring sensor (not shown) would be affixed to a left side of the nursing bra 200 for monitoring a left breast, and communicate with the controller 250. [0076] The controller 250 communicates information from the milk flow monitoring sensor 210, including a total milk flow mass or volume, body temperature, activity, time, date, duration of the feeding session, and other data. The nursing mother may add other information (Parent Input 252), such as the infant’s weight post-feeding, weight change, condition of the infant (e.g., alert, sleepy, fussy, etc.), diaper status, and other information. There may also be other information communicated from a third party (3 ^rd Party Input 254). Such information may include information from a present feeding session, historical data, diurnal analysis, trend data, comparative analysis, etc. The foregoing information may be subjected to analysis to identify trends, outliers, etc., and communicated via an application on a cell phone, tablet or other device to a parent via a parent-specific application (270). The foregoing information may be subjected to analysis to identify trends, outliers, etc., and communicated via an application on a cell phone, tablet or other device to a medical professional or another advisor via a professional-specific application (280). Analysis of the bio-impedance data may be executed in real-time and/or off-line. The bio-impedance data is captured during the milk expression and is pooled with other data, either in the controller 260 or in a cloud environment. [0077] FIG.4 pictorially illustrates an embodiment of a breast milk flow monitoring system 400 that includes milk flow monitoring sensor 410 that is in communication with controller 450 via wiring cable 415, analogous to the breast milk flow monitoring system 100 that is described with reference to FIG.1. In this embodiment, the milk flow monitoring sensor 410 is arranged on an adjustable band 412 that may be substantially conical in shape and with a fastener 414 to facilitate adjustment of the length and thus adjustment of the diameter of the adjustable band 412. The milk flow monitoring sensor 410 includes first and second electrode pairs 420, 430, respectively, with electrodes 421, 422, 431 and 432.

Alternatively, or in addition, the milk flow monitoring sensor 410 may include one or a plurality of strain gages. [0078] The capability to adjust the length and thus the diameter of the adjustable band 412 allows for adaptation of the milk flow monitoring sensor 410 to different breast sizes. The adjustable band 412 is fabricated from silicone or another material, using extrusion, molding, or other methods. The milk flow monitoring sensor 410 is configured to be placed directly onto the skin of the breast in an arrangement that enables the electrodes of the first and second electrode pairs 420, 430 to have direct contact with the skin of the breast, without interfering with infant feeding.

[0083] FIG.9 schematically illustrates a front view of a female torso including a breast 900 having a nipple 909 and an areola 910, and having a plurality of anatomical landmarks identified on the surface thereof. The anatomical landmarks describe potential target locations for the electrodes of an electrode pair or an electrode array that is employed by one of the embodiments of the milk flow monitoring sensor that is described herein. The anatomical landmarks include a superomedial location distal to an areola 901, an inferomedial location distal to an areola 902, an inferolateral location distal to an areola 903, a superolateral location distal to an areola 904, a superomedial location proximal to an areola 905, an inferomedial location proximal to an areola 906, an inferolateral location proximal to an areola 907, a superolateral location proximal to an areola 908. As used herein, the terms “distal” and “proximal” indicate the relative distance, on the skin surface of the breast, of the exemplary locations relative to the areola 910. For example, the proximal locations 905, 906, 907, 908 on the skin surface of the breast 900 are located closer to the areola 909 than the distal locations 901, 902, 903, 904 on the skin surface of the breast 900. The distal locations 901, 902, 903, 904 on the skin surface of the breast 900 are located further away from the areola 901 than the proximal locations 905, 906, 907, 908 on the skin surface of the breast 900. Furthermore, distances from the areola 901 for the proximal locations 905, 906, 907, 908 may all be the same in one embodiment. Alternatively, distances from the areola 901 may be different for individual ones of the proximal locations 905, 906, 907, 908. In like manner, distances from the areola 901 for the distal locations 901, 902, 903, 904 may all be the same in one embodiment. Alternatively, distances from the areola 901 may be different for individual ones of the distal locations 901, 902, 903, 904. Furthermore, the proximal locations 905, 906, 907, 908 and distal locations 901, 902, 903, 904 are shown as being oriented along lines of 45 degrees, 135 degrees, 225 degrees, and 315 degrees in relation to a common plane that is defined by being parallel to a chest wall, but the concepts for placement of the electrodes is not so limited. The placements may be at other orientations, determined during calibration or another event, to optimize or maximize signal integrity from the electrodes. [0084] In one embodiment, the first electrode of the electrode pair or electrode array is arranged to contact the skin surface of the breast 900 at one of the superomedial location distal to the areola 901, the inferomedial location distal to the areola 902, the inferolateral location distal to the areola 903, the superolateral location distal to the areola 904, the superomedial location proximal to the areola 905, the inferomedial location proximal to the areola 906, the inferolateral location proximal to the areola 907, the superolateral location proximal to the areola 908.

[0085] The electrodes of each electrode pair or electrode array may be placed in a common plane that is defined by being parallel to a chest wall, orthogonal to a chest wall, along a line that is defined by a lateral axis, or along a line that is defined by a longitudinal axis. Alternatively, the electrodes of each electrode pair or electrode array may be placed in an oblique plane relative to the chest wall, or oblique to a lateral axis, or oblique to a longitudinal axis. Examples of common planes include a parallel plane including locations 901, 902, 903, 904; a parallel plane including locations 905, 906, 907, 908; an orthogonal plane including locations 901, 904; an orthogonal plane including locations 903, 904; an orthogonal plane including locations 904, 906; an orthogonal plane including locations 903, 905; an orthogonal plane including locations 905, 906; an oblique plane including locations 901, 904, 905, 908; an oblique plane including locations 901, 904, 906, 907; an oblique plane including locations 903, 904, 905, 906, etc. The examples of common planes definable by the locations provided herein are illustrative and non-limiting, and it would be understood that electrode pairs can be placed in locations on the skin surface of the breast in addition to the exemplary locations shown in the drawings, and within common planes which may be parallel, orthogonal or oblique to the chest wall, in addition to the exemplary common planes described herein. [0086] Positioning of the milk flow monitoring sensor on the breast can be indicated via instructions on a software application that is uploaded onto a handheld device such as a cellular phone or a tablet, or light projected on the breast to indicate correct or incorrect positioning, or a visual indicator on the cellular phone that utilizes an on-board camera to assess electrode positions, along with a still photograph or video of the milk flow monitoring sensor on the breast. A secondary positioning device may be used to position or profile the electrodes in an acceptable position. Computer vision algorithms may be used with the breast motion monitor to indicate correct or incorrect positions as display in real-time on a picture or video of the breast. [0087] In operation, the controller 50 generates an excitation signal that is calibrated for breast milk flow. The controller communicates the excitation signal via the first electrode to the surface of the breast. [0088] The second electrode of the milk flow monitors a current response signal that is responsive to an excitation signal that is transferred to the skin of the breast via the first electrode. The bio-impedance spectroscopic analysis accounts for resistance of tissue or subcutaneous fluid under the skin, mammary glands, and milk contained within. As milk flows, is ejected, sucked or expressed out of the breast, bioimpedance values change in relation to fluid leaving the breast. Bioimpedance values can be calibrated to indicate fluid levels of milk in the breast, amount of milk that has left the breast via pumping or feeding by an infant. [0089] FIG.10 schematically shows a flowchart 950 that is associated with an embodiment of the breast milk flow monitoring system described with reference to FIGS.1-8, which illustrates actions and information flow related to utilizing an embodiment of the breast milk flow monitoring system to determine breast milk flow in-use. [0090] Prior to milk expression by nursing or pumping, breast milk will build up near the nipple area within the breast in response to an oxytocin release and other factors (Step 951). The breast milk flow monitoring system is positioned on the breast, either directly or through a pump interface or shield (Step 952), and milk flow commences as a result of feeding or pumping, with the milk flow monitoring sensor periodically capturing data (Step 953). [0091] The milk flow monitoring system may include an auto-trigger to commence milk flow monitoring upon detection of milk flow. Alternatively, the milk flow monitoring system may have a manually operated trigger that is activated by the nursing mother. The manually operated trigger may be included on the physical controller 50, or as part of a user application that is executed on a hand-held device. [0092] When milk flow commences as a result of pumping (Step 960), milk is captured via a breast pump retainer or bottle (Step 961), and the captured milk volume and/or milk mass is measured and recorded (Step 962). [0093] When milk flow commences as a result of feeding (Step 980), the infant consumes the milk directly (Step 981), and the infant’s mass may be captured post-feeding, along with other data (Step 982). Other data may include, but not be limited to infant weight, weight change, condition of the infant (e.g., alert, sleepy, fussy, etc.), the mother’s interpretation of when the infant was actually feeding, and whether or not the infant consumed breast milk during the feeding session. [0094] Analysis of the bio-impedance data may be executed in real-time and/or off-line (Step 970). The bio-impedance data is captured during the milk expression and is pooled with other data, either in the controller or in a cloud environment (Step 971), along with the data from conditions 960 and 980. The data from Steps 960, 980, and 970 is employed to fine-tune the calibration equation (Step 972). [0095] The analysis of the bio-impedance data that is captured during the milk expression may be pooled with other data for calibration development, and pooled with other data, either in the controller or in a cloud environment [0096] Information captured and/or derived from the feeding session is communicated to the nursing mother and/or others, via one or more user interfaces that are defined by the user application, and may be accessible via a cellular phone, tablet, computer, etc. The outputted information may include information for each breast (left or right), from a present feeding session, historical data, diurnal analysis, trend data, comparative analysis, etc. (Step 983). [0097] The data from Steps 962, 982 and 971 may be transmitted from the controller to the cloud environment for analysis, calibration, etc. (Step 983). Sensor and/or bio-impedance data may be associated in a database with one or more of the subject infant, the nursing mother, time of day, start time, and elapsed time of nursing or pumping, date, duration of the feeding session, and other data such as body temperature, infant weight, weight change, condition of the infant (e.g., alert, sleepy, fussy, etc.). Data may further be associated with a pool of subject infants and/or subject nursing mothers that are defined as having one or more common parameters, and/or otherwise associated into data grouping for analysis and calibration development. [0098] In this description and the following claims, “cloud computing” may be defined as a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned via virtualization and released with minimal management effort or service provider interaction, and then scaled accordingly. A cloud model can be composed of various characteristics (e.g., on-demand self-service, broad network access, resource pooling, rapid elasticity, measured service, etc.), service models (e.g., Software as a Service (SaaS), Platform as a Service (PaaS), Infrastructure as a Service (IaaS), and deployment models (e.g., private cloud, community cloud, public cloud, hybrid cloud, etc.).

The non-transitory memory component is capable of storing machine readable instructions in the form of one or more software or firmware programs or routines, combinational logic circuit(s), input/output circuit(s) and devices, signal conditioning, buffer circuitry and other components, which can be accessed by and executed by one or more processors to provide a described functionality. Input/output circuit(s) and devices include analog/digital converters and related devices that monitor inputs from sensors, with such inputs monitored at a preset sampling frequency or in response to a triggering event. Software, firmware, programs, instructions, control routines, code, algorithms, and similar terms mean controller-executable instruction sets including calibrations and look-up tables. Each controller executes control routine(s) to provide desired functions. Routines may be executed at regular intervals, for example every 100 microseconds during ongoing operation. Alternatively, routines may be executed in response to occurrence of a triggering event. Communication between controllers, actuators and/or sensors may be accomplished using a direct wired point- to-point link, a networked communication bus link, a wireless link, or another communication link. Communication includes exchanging data signals, including, for example, electrical signals via a conductive medium; electromagnetic signals via air; optical signals via optical waveguides; etc. The data signals may include discrete, analog and/or digitized analog signals representing inputs from sensors, actuator commands, and communication between controllers. [00100] The use of ordinals such as first, second and third does not necessarily imply a ranked sense of order, but rather may only distinguish between multiple instances of an act or structure. [00101] The term "signal" refers to a physically discernible indicator that conveys information, and may be a suitable waveform (e.g., electrical, optical, magnetic, mechanical or electromagnetic), such as an analog signal, a digital signal, sinusoidal-wave, triangular-wave, square-wave, vibration, and the like, that is capable of traveling through a medium. [00102] The terms “calibration”, “calibrated”, and related terms refer to a result or a process that correlates a desired parameter and one or multiple perceived or observed parameters for a device or a system. A calibration as described herein may be reduced to a storable parametric table, a plurality of executable equations or another suitable form that may be employed as part of a measurement or control routine. [00103] A parameter is defined as a measurable quantity that represents a physical property of a device or other element that is discernible using one or more sensors and/or a physical model. A parameter may be a discrete value (e.g., either “1” or “0”), a percentage (e.g., 0% to 100%), or an infinitely variable value.
