FIELD OF THE INVENTION

This invention relates to communicating with equipment operating underwater and more particularly, although not necessarily exclusively, to concepts and methods for communicating underwater with autonomous vehicles such as automatic pool cleaners (“APCsfo configured to operate in swimming pools or spas.

BACKGROUND

U. S, Patent No. 9,250.626 to Michelon describes an exemplary apparatus (often called a "robot" or a ‘'robotic ARC ) for cleaning a swimming pool. The apparatus includes wheels or other motive elements and is configured to travel autonomously within the pool. It further may be connected via cable to an intermediate relay" or control box, positioned near the pool. The external control box may receive signals from a wireless transmitter of a remote control device and forward control information to the cleaning apparatus through the cable. In particular, because of known difficulties m transmitting wireless radio frequency (RF) signals substantial distances through water, the control box is not positioned within the pool, nor does the wireless transmitter of the remote control device communicate directly with the underwater ARC. The control box thus indeed functions as tat “intermediate relay in that it receives control information wirelessly externally of the pool and relays it via wire to the submerged cleaner within the pool

U.S. Patent Application Publication No. 2020616)63454 of Attar, et a!., discusses another robotic APC to which a control cable is connected. Consistent with conventional devices, the cleaner of the Attar application receives signals via wire from an external source. As noted in the Attar application, the cable is subject to being pulled for various reasons; although such pulling is disadvantageous in some eases, the cleaner of the Attar application describes using sensed directional pulling information to control certain movements of the cleaner:

FIGS. 1 and 2 illustrate an example of a pool system 100 according to various embodiments. The pool system 100 includes a body of water 101 and a communication system 103 for controlling at 1 east one piece of equipment 104 submerged in the body of water 101 . Optionally, the communication system 103 includes a sound generator 122.

In the embodiment of FIGS. 1 and 2, the piece of equipment 104 is a battery-powered, robotic APC 106 that may be submerged within the water 101. The APC 106 includes a body 108, a communication sensor 118, and a controller 120 communicatively coupled to the communication sensor 118. Tire communication sensor 118 may be various suitable devices or combinations of devices for receiving transmitted sounds 124 and/or other signals, such as from the sound generator 122 In the embodiment of FIG. 1 , the communication sensor 118 is a microphone 126 on the APC 106 that may receive the sounds 124 and convert them, in conventional manner, into electrical signals that may be transmitted to the controller 120. in some embodiments, the communication sensor 118 optionally may be positioned on a. printed circuit board (PCB) within a motor block of the body 108 of the APC 106. in these examples, the communication sensor 118 may be in a sealed compartment or area of the APC 106 and/or otherwise isolated from die water 101 , thereby minimizing possible detrimental effects of pool water on the communication sensor 118. in other embodiments, the communication sensor 118 may be located elsewhere on or in the APC 106. in certain embodiments, the communication sensor 118 may optionally be remote from (e.g., not physically attached to) the APC 106, including, tint not limited to, a remote location within the body of water 101 and/or a remote location 128 outside the body of water 101.

While a single communication sensor 118 is illustrated in FIG. 1, in other embodiments, the APC .106 may include more than one communication sensor 118, such as two communi cation sensors 118, three communication sensors 118, or more than three communication sensors 118 in such embodiments, the plurality of communication sensors 118 may be the same ty pe of communication sensor ie.g., they are all microphones 126) or may be different types of communication sensors (e.g., one is a microphone and another is an ultrasonic transducer or other receiver as desired), in one non-limiting embodiment, an APC 106 may include at least at least two microphones, ultrasonic transducers, and/or other receivers as communication sensor 118 spaced about the APC 106, or at least three microphones, ultrasonic transducers, and/or other receivers as communication sensor 118 spaced about the APC 106. Including at least two microphones, ultrasonic transducers., and/or other receivers as communication sensor 118 spaced about the APC 106 optionally may facilitate a determination of the location and/or orientation of the piece of equipment 104 within the water 101, as discussed below.

The controller 120 may be various statable computing devices as desired with a processor and/or a memory, in certain embodiments, the memory may be coupled to the processor, and the memory may include instructions that may be executed by the processor, in various embodiments, the controller 120 receives the electrical signals from the communication sensor 118 and processes them to control the APC 106. In some embodiments, the controller 120 optionally may be operably coupled to various sub-components of the APC 106 ie.g., motor. pump, debris filter, etc.) and may selectively control those sub-components, optionally based on the electrical signals from the communication sensor 118. As some non-limiting examples, and as discussed in detail below, based on the electrical signals from the communication sensor 118, the controller 120 may control a position and/or orientation of the APC 106 within the water 101, a direction of travel of the APC 106 within the water 101, an activation of a pump or motor, combinations thereof, or other suitable controls as desired. Optionally, the APC 106 may travel within the water 101 of the pool system 100 and may be programmed to come to rest on the bottom surface of the pool when a cleaning cycle is completed and/or when its battery is low.

As mentioned, in addition to the communication sensor(s) 118 and the controller 120, the APC 106 may include other optional features as desired. Optionally, the APC may include one or more motive elements 110 for moving the APC 106 within the body of water 101. Suitable motive elements 110 include, but are not limited to, wheels, tracks, rollers, feet, combinations thereof, and/or other suitable devices or mechanisms as desired. Additionally or alternatively, the APC 106 may also include one or more of an electric motor 112, a pump 114, and a debris filter 116. In certain embodiments, the components of the APC 106 optionally may be communicatively coupled to the controller 120 and/or selectively controlled by the controller

120. The particular features illustrated with the APC 106 should not be considered limiting. and in other embodiments, the APC 106 may include fewer and/or additional features as desired. As two non-limiting examples, in other embodiments, the APC 106 may be similar to that described in U.S. Patent No. 9,250,626 to Michelon or in U.S Patent Application

Publication No. 2020/0063454 of Attar, et al., both of which are hereby incorporated by reference m their entireties. In other embodiments, the piece of equipment 104 may be other pieces of equipment tor a pool as desired.

In addition to the piece of equipment 104, the communication system 103 optionally includes the sound generator 122, which may be used to control the piece of equipment 104 using sound 124. In various embodiments, the sound generator(s) 122 optionally may be various suitable devices or components lor generating the sound 124, including, but not limited to, vanous mechanical and/or electrical devices as desired. In other embodiments, the sound generator 122 may be a human eliminating the need for electrical or mechanical sound maker and providing an easy, hands tree technique for communicating with the APC. In the embodiment of FIG. 1, the sound generator 122 is a mechanical sound generator 130 with a sound maker 132 that selectively generates the sound 124. The sound 124 generated by the sound generator 122 may be various types of sounds as desired, and the sound 124 need not be a. sound audible to a human As some non-limiting examples, the sound 124 generated by the sound generator 122 may include, but is not limited to, audible pulses made by stomping feet or clapping hands, spoken words, ultrasonic signals, low frequency sounds below normal audible ranges, combinations thereof and/or other sounds 124 as desired for communicating with the piece of equipment 104. in some embodiments, and as illustrated in FIG. 1, the sound generator 122 may be provided at a location 128 that is outside of the body of water 101 such that the sound 124 travels both through air and the water 101 , In other embodiments, and as illustrated in FIG. 2, the sound generator 122 may be provided in the body of water 101 such that the sound generator 122 is underwater and sound 124 travels only underwater.

While a single sound generator 122 is illustrated in FIGS. 1 and 2, in other embodiments, the pool system 100 may nave any desired number of sound generators 122 as desired, in certain embodiments, the pool system 100 may include at least two sound generators 122 spaced about the body of water 101. In some embodiments, and as discussed in detail below, employing at least two sound generators 122 spaced about the water 101 may optionally facilitate a determination of the location of the piece of equipment 104 within the water 101.

FIG. 3 illustrates another example of a pool system 300 according to various embodiments. The pool system 300 is substantially similar to the pool system 100 except that the piece of equipment 104 is an APC 306 that is substantially similar to the APC 106 but further includes an onboard sound generator 334. In tins embodiment, the sound generator 334 may selectively generate a sound or other signal 336. Optionally, the signal 336 is generated by the sound generator 334 responsive to a sound 124 from the sound generator 122, although it need not. In certain embodiments, the sound generator 334 may allow for the APC 306 to “talk back” to a microphone or other communication sensor located within or outside the pool, including, but not limited to, a microphone or other communication sensor on or associated with the sound generator 122. In other embodiments, other forms of communication from the APC to external devices could be used instead. lit some embodiments, the APC 106 or 306 is configured to enter a quiet mode, whereby the electric motor 112 and/or the pump 114 and/or other subcomponents of the APC 106 or 306 are de-energized so the communication sensor(s) 118 are able to receive the signal from the source without interference from noise generated by the electric motor 112 or other subcomponents. In some cases, the APC 106 is configured to enter the quiet mode (e.g., the motor and/or other components are turned off so the APC 106 is in a listening mode) when the APC 106 ends a. cleaning cycle. In other embodiments, the APC 106 may be preprogrammed to enter a quiet mode at predetermined intervals In yet other embodiments, the APC 106 may be switched to quiet mode as desired via the controller 120.

As mentioned, the communication systems 103 described herein may be used to control the piece of equipment 104 and/or determine other characteristics of the pool system 100. As one non-limiting example, the communication system 103 may be used to facilitate determination of the orientation of the APC 106 within the water 101 and/or the direction of the sound from the source using the communication sensoris) 118. For example, two or more microphones, ultrasonic transducers, and/or other receivers as communication sensor 118 spaced about the APC 106 (optionally on the same APC 104) and receiving the same signal from the source at different tunes may be used to calculate the relative distances of the communication sensor(s) 118 from tire source (e.g., a single sound generator 122), thereby providing information about the orientation of the APC 106 within the body of water 101 and/or about the direction of the source of the sound. More specifically , the ACF 106 can determine the direction from where the sound emanates and/or orientation of the APC 106 through triangulati on/the difference in time of arrival to each microphone or other communication sensor 118 of the sound. With three or more communications sensors 118, an absolute direction for the sound source can be determined and acted upon through triangulation using the difference of arrival time of the sound signal to the three or more communication sensors 118.

In other embodiments, the communication seasons ) 118 may be utilized to provide additional information about the APC 106 as desired. In an alternative embodiment, one or more microphones, ultrasonic transducers, and/or other receivers as communication sensor 118 may be positioned on a charging/base station, in which case the base station determines the direction of the sound and/or an orientation of the APC 106 through the same means.

As another non -limiting example, in embodiments with a plurality of sound generators 122, when the one or more communication sensors 118 receive two separate signals, the difference in receipt times may allow calculation ofrelative distances of the APC 106 from each of the sources, hence supplying information as to the location of the APC 106 within the water 101. As another non-- limiting embodiment, two spaced microphones 126 (optionally on the same APC 104) receiving the same signal at different times may be used to calculate the relative distances of the microphones 126 from the source (e.g., a single sound generator 122), thereby providing information about the location of the APC 106 relative to the source, in other embodiments, the communication sensor) s) 118 may be utilized to provide additional information about the APC 106 as desired. in certain embodiments, information or data may be communicated with the APC 106 based on at least one characteristic of the sound (or other) signals. The at least one characteristic of the sound 124 may include, but is not limited to, a pattern of the sound 124, a volume of the sound 124, a frequency of the sound 124, a duration of the sound 124, a location that the sound 124 originates from, a pitch of the sound 124. voice recognition parameter data of the sound 124 (e.g., a parameter of a person's voice when speaking), combinations thereof, or other suitable characteristics as desired. In these embodiments, the controller 120 may receive the at least one characteristic of the sound 124, determine a corresponding control action based on the at least one characteristic of the sound 124, and control the APC 106 based on the determined control action. In certain examples, the controller 120 may optionally perform voice recognition on the at least one characteristic and may control the APC 106 based on such voice recognition. Additional non-limiting examples of such control by the controller 120 are provided below, but other types of control are possible, and the examples are merely provided for illustrative purposes.

In one non-limiting example, the robotic APC 106 within a swimming pool may be signaled when a homeowner or oilier pool user or technician desires to remove the APC 106 from the pool by generating a sound 124 having a pattern of taps (e.g., six taps ) of short duration, in this example, the signals may instruct the APC 106 to begin movement along the bottom surface of the pool until n readies any upstanding wall and then climb the wail for presentation to the user at the waterline of the pool. In another non-limiting example, the APC 106 may be instructed to turn toward the user and move within the pool until it reaches the wall closest to the user, following which it climbs the wall for presentation at the waterline. In this embodiment, the human or sound generator may generate a sound 124 having another pattern of taps (e.g., three taps) of long duration. In the first example, the user must walk along the pool deck to retrieve the APC 106 at the waterline, whereas in the second circumstance, the APC 106 presents itself for retrieval in the immediate vicinity of the user.

As a further non-limiting example, the controller 120 may be configured to recognize signals from the communication sensor 118 corresponding to numbers of audible pulses of sound 124 made by foot stomps For example, sound 124 created by two (or other number of) foot stomps in succession on the pool deck may be received by the communication sensor 118 and converted into signals recognized by the controller 120 as an instruction to ‘ ' wake up’ " and energize components to prepare to receive further instructions. In this example, the controller 120 may optionally activate the motive elements 110 briefly to cause the APC 106 to move slightly within dm water 101 of the pooh effectively providing a visual acknowledgment that the ‘ " wake up " ’ instruction was received and processed. Should the communication sensor 118 of the APC 106 of tins example then receive sounds corresponding to four (or other number of) foot stomps in succession, the controller 120 may interpret dm information as an instruction to commence generally-linear movement until an upstanding wall is sensed and then to climb tire wail for presentation of the APC 106 at the waterline. By contrast, if upon waking the APC 106 is not oriented in a preferred manner, the human may supply three (or other number of ) foot stomps in succession to cause the APC 106 to rotate approximately 45°. Additional iterations of three for other number of) foot stomps each may cause a further rotation of approximately 45° (in tire same clockwise or counter-clockwise manner) until the APC 106 is oriented as desired, following which four (or other number of) foot stonrps may commence linear movement of the device.

As another non-limiting example, the robotic APC 106 within a swimming pool may be signaled by a person ' s voice. For example, when a homeowner or other poo! user or technician desires to remove the APC 106 from the pool, they may speak to the APC 106 as a sound 124 with the instructions that the user wants the APC 106 to perform. The controller 120 may recognize such instructions and may cause the APC 106 to perform the action accordingly. Recognizing the instructions may be any voice recognition technique as desired, including, but not limited to. comparing the received instructions to predefined or preprogrammed instructions. Optionally, the APC 106 with the voice recognition may allow for a layer of security and/or safety using voice verification such that only authorized users may control the APC 106. For example, an unauthorized user and an authorized user may sneak the same command to the APC 106, but the controller may only control the APC 106 pursuant to the authorized user s command based on voice recognition of the authorized user. As another non- limiting example, a child (e.g., an unauthorized user) may tell the APC 106 to surface Mule a. parent (e.g., an authorized user) may tell the APC 106 to stay submerged, and the APC 106 will stay submerged pursuant to the parentis voice instructions (or stay submerged even in the absence of the parent ' s voice instructions since tire surface instructions were given by an unauthorized user).

Although the foregoing examples are useful m describing aspects of tire invention, persons skilled m the art will recognize that the invention is not limited to use of any particular ones of the disclosed actions. As noted above, sounds need not necessarily be audible, nor need they necessarily be created by foot stomping outside the pool.
