Abstract:
A radio frequency (“RF”) remote control device for use to control the speed of a motor is disclosed. In one preferred embodiment, the device may be used by a swimmer in a swim spa. The RF device can be preferably formed in shape of a glove to be worn by the athlete/swimmer, such that he or she can readily change the speed of the swim spa current motor, and in turn the speed of the current he or she is swimming against simply by activating respective increase or decrease motor speed signals. In further embodiments, the RF device can also include a stop watch to record duration of exercise, and/or an automatic stroke counter to record the number of strokes during the exercise.

Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to wireless remote control devices and systems. More particularly this invention relates to devices, systems and methods using radio frequency technology to remotely control a motor, which in turn may be used as part of exercise equipment to control the speed or exertion level of the exercise. Still more particularly, the device and system may be used to control the drive or current motor in a swim spa to control current speed. The device may be formed as a complete or partial glove to be worn by a user, and is used as part of a system including radio frequency (“RF”) circuits such that the user can activate and wirelessly send RF signals to a motor controller to increase or decrease the motor speed, or alternatively to stop the motor. As used in a swim spa setting, the device allows the user to control water current without interrupting his or her exercise and swim stroke. In the form of a glove, the user has an intuitive and easy means of precisely controlling the motor driving the speed of the swim current. 
         [0002]    In further embodiments, the device can be augmented to include a stop watch to monitor duration of the exercise, and/or the device can include a built in stroke counter to automatically record the number of swim strokes during the exercise. A further enhanced embodiment would include a heart rate monitor position within the glove device, with such sensed data being wirelessly transmitted to a local display device. Still further embodiments of the system may include a computer processor with associated data memory such that the time history of the motor speed may be recorded and stored in the computer processor data memory, which can then be available for recall to drive the current motor and allow the user to repeat the recorded motor speed time history. 
       BACKGROUND OF THE INVENTION 
       [0003]    Motors, including electric and hydraulic motors, are used to drive or move many different items or media, include air (e.g., fans) or water (e.g., pumps or fans). The ability to precisely control the speed of the motor is often a critical aspect of proper and/or efficient use of the motor. For example, in various exercise embodiments, including treadmills or swim spas, the control of the motor speed equates to the control of the speed of the treadmill or swim current, and thus, the speed at which the exercise is accomplished and the user&#39;s or athlete&#39;s exertion level. 
         [0004]    Various means of controlling a motor&#39;s speed, both directly and remotely have been used for decades. Several examples of such remote control devices are described herein. 
         [0005]    A remote control system for use with a boat trolling motor is disclosed in U.S. Pat. No. 6,054,831, issued to Moore et al., specifically for a Radio Frequency Remote Control For Trolling Motors. As described in the &#39;831 patent, the remote control is through a foot actuated switching device that can either control the motor through radio frequency signals or infrared signals. Nothing in the &#39;831 patent teaches use of a hand worn device to control the trolling motor speed. 
         [0006]    A casement window opening and closing mechanism is taught in U.S. patent application Ser. No. 12/798,038, by Thorne, entitled RF-Remote Control, Retrofitted Self-Contained, Automatic Window Opener For Casement Windows Or The Like. More specifically, the &#39;038 application discloses a remote control system, including a battery powered DC electric motor to open and close casement windows using remote control through radio frequency (“RF”) signals. As with the &#39;831 patent, there is no disclosure of any hand-worn control mechanism to actuate the motor control. 
         [0007]    European Patent Application No. 0923060, for a Wireless Remote Control System For Electrical Devices, by Depauw, discloses a system using a plurality of RF transmitters and RF receivers to remotely control pumps, motors, heaters, and lights. The RF receivers are electrically connected to the particular device to be controlled and the RF transmitters are remote from the RF receiver or devices to be controlled. Upon activation by a user, the RF transmitter sends an RF signal to the RF receiver to turn on or turn off the device to be controlled. The &#39;060 application does not disclose use of a hand worn control device in association with the RF transmitter. 
         [0008]    U.S. patent application Ser. No. 13/303,090, for a Ruggedized Control Glove Allowing Dynamic Balance And Undivided Visual Attention, by Rott et al., more particularly discloses a wireless control glove for use with powered rideable boards, mobility devices, or remote-controlled (“RC”) models. As described in the &#39;090 application, the glove may be configured with an input transducer, a transceiver, and an output transducer to permit the user to enter acceleration and steering commands. While the &#39;090 application device does use a glove to provide wireless remote control signals for controlling powered boards, mobility devices and RC models, the device also requires a power supply and electrical circuitry that is integral as part of the glove. Also, although the glove is described as being “ruggedized,” there is no disclosure that the glove may be immersed in water or a water environment. Accordingly, even if“ruggedized,” having electricity in a water environment, or where the glove may be immersed in water, is not the safest usage. Moreover, there is no suggestion in the &#39;090 application of any means to record and playback the control inputs from the glove. 
         [0009]    Similarly, U.S. Pat. No. 7,109,970, for an Apparatus For Remotely Controlling Computers And Other Electronic Appliances/Devices Using A Combination Of Voice Commands And Finger Movements, by Miller, teaches a three-finger apparatus to be worn on the user&#39;s hand that comprises a plurality of touch-sensitive touchpads and/or motion sensitive elements, and a microphone, all used to operate a computer or the on-screen cursor. Although the &#39;970 patent discloses a device to worn on a user&#39;s hand, the control mechanism is directed solely to enter commands into a computer, thereby replacing the need for an associated computer mouse. There is no suggestion or motivation to use the &#39;970 patent apparatus to remotely control exercise equipment or electric or hydraulic motors. Moreover, the &#39;970 patent device, similar to the &#39;090 application device requires that electrical power be incorporated into the hand worn element. As such, like the &#39;090 application device, including electrical power supplies within a hand worn device that is to be used in a water environment or where the device may be fully immersed in water, is simply not recommended or safe. Further, similar to the &#39;090 application device, there is no suggestion in the &#39;970 patent of any means to record and playback the control inputs from the hand worn device. 
         [0010]    While certain of these devices appear to address the problem of controlling a motor through remote means, or to provide a device worn on a user&#39;s hand to control a computer or recreational equipment, none is directed to solving the problem of controlling the speed of a motor used on exercise equipment, including a treadmill or swim spa, and permitting recording and playback of a time history of the exercise equipment motor speed. As such, these problems, as well as other deficiencies are intended to be overcome and solved by the present invention. 
         [0011]    Accordingly, it would be desirable to have a wireless remote control for a motor that is used, for example, with various exercise machines, where the remote control includes a device that is worn on the athlete&#39;s hand, including such as a glove or partial glove, and the exercise machine motor speed control is intuitively and easily controlled by finger activation or touching of various parts of the glove to either increase or decrease the motor speed, or stop the motor altogether. It would be further desirable to have incorporated with the remote control device a stop watch and/or an automatic stroke counter to count swim strokes. It would also be desirable to have a computer processor in communication with the remote control system to record a time history of the motor speed, such that the recorded and stored time history can be later recalled from the computer processor memory and used to drive the exercise equipment motor at a future time, thereby reproducing the motor speed and exercise routine for the athlete. Such improvements and results have not been seen or achieved in the relevant art.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
       [0028]    The present invention is a hand worn device and associated system to allow a user to remotely control the speed of an electric motor using wireless technology, such as radio frequency or infrared signals. A key element of the device and system is worn on the user&#39;s hand and is designed to provide an intuitive means for the user to increase or decrease the speed of the motor, or to stop the motor completely. In certain preferred embodiments, the inventive device and system may be used by an athlete to control the speed of a treadmill (for a walker or runner), or the current speed of a swim spa (for a swimmer). Another element of the system, in an enhanced embodiment, is a computer processor with associated memory to record one or more time histories of the speed of the exercise equipment motor. As recorded, the motor speed time histories may be later recalled and “replayed” to control the equipment motor speed thereby allowing the athlete or user to repeat the exercise exertion level previously recorded. 
         [0029]    In an exemplary embodiment, as illustrated in  FIGS. 1A ,  1 B, and  2 , the control device  10  may be a glove or partial glove to be worn on the user&#39;s hand. The control device  10  may be, as shown, configured to be a glove that may be worn on a user&#39;s left or right hand. In terms of operation, in one preferred embodiment, the glove has incorporated into the glove material, in particular locations, a plurality of radio frequency identification (“RFID”) passive tags  30  that are intermittently or continuously polled by a remote RFID receiver or reader  50 . The RIFD receiver or reader  50  should be located within close proximity of the user or athlete  90  and the glove  10 . Because the environment in which the glove  10  is intended to be used may be in or near water, or in a sweat prevalent area, it is desired that the glove  10  not have any electrical power source, including any battery, incorporated into the glove  10 . Such power sources, or electricity connected to the glove  10  could cause an undesired electrical pulse or charge being felt by the user  90 . 
         [0030]    While various wireless technology signals, other than radio frequency (“RF”) or RFID, could be used for the inventive control system, several of these signal technologies require a power source to operate. For example, while infrared (“IR”) signals could also be used to provide control signals from the glove  10  to a receiving unit  50 , such signals generally require a power source. Moreover, IR transmissions typically require an approximately clear line-of-sight between the transmitting and receiving elements to be fully effective. By contrast RF or RFID signals, and in particular low frequency (“LF”), high frequency (“HF”), and ultra-high frequency (“UHF”) passive RFID tags do not need or have electrical power sources, and are not limited to having a clear line-of-sight between the sending and receiving units. Such RFID devices are accordingly more likely to be useful for certain of the exemplary embodiments. 
         [0031]    Still further alternative technology, being Near Field Communication or “NFC” offers another variant of wireless technology (similar to RFID) that is currently being incorporated for use with smartphones. While NFC wireless technology may be, in the future, useful for wireless remote motor control, current NFC technology is likely not acceptable with respect to proximity limitations. More particularly, NFC require a very close proximity between a reader and the tag to be workable. More specifically, while the theoretical working distance for NFC tags with compact standard antennas is indicated to be up to 20 cm, the acknowledged practical working distance of such tags is more in range of 4 cm. As such NFC technology may provide an alternative communication means in the future with improved antenna technology, but is not likely to be reasonable feasible or workable for the exemplary embodiments at the time of the filing of this application. 
         [0032]    In further operational detail, using RFID technology for an exemplary embodiment,  FIG. 2  illustrates the inventive system used for a swim spa. More specifically, the proximity of the reader or receiver  50  must be close enough to the passive tags  30  such that when the reader  50  interrogates (by emitting radio waves  51 ) the passive tags  30 , the tag or tags  30  are within the reader&#39;s range  60  to be energized, and then provide a return signal back to the reader  50 . The way passive RFID tags  30  operate is that when radio waves  51  from an RFID interrogator/reader  50  reach the passive tag&#39;s antenna, the RF energy is converted into electricity to power the passive tag&#39;s microchip. The passive tag  30  can then transmit the chip&#39;s stored data back to the reader/interrogator  50 . While the read range of passive RFID tags  30  depends on several factors, including the frequency of radio waves used for the tag-reader communication, the size of the tag antenna, the power of the reader, and interference from metal objects or other RF devices, it is acknowledged that certain passive tags, which have no power source, can be read by a reader or receiver  50  at up to approximately 15 to 20 feet. 
         [0033]    Active RFID tags, as compared to passive RFID tags  30 , require an installed power source, but can be read at significantly larger distances, up to, by way of example, 300 feet or more. Such active tags are often used for roadway toll collection systems. Given the desire to not have an electrical power source incorporated into the glove element  10 , it is not anticipated that active RFID tags would or should be used in certain exemplary embodiments. 
         [0034]    With respect to the frequency of operation, RFID readers and tags generally have four ranges of radio frequency for operation, being low, high, ultrahigh and microwave. Low-frequency (“LF”) tags operate between 125 kHz to 134 kHz, are less subject to interference, and are generally better suited for environments with metal or high moisture or water. However, LF tags have a read range of about one foot. High-frequency (“HF”) tags operate at between 13 to 14 MHz and have a read range of approximately 3 feet. Moreover, HF tags transmit data faster than LF tags, and are often used in smart cards. 
         [0035]    Ultra-High Frequency (“UHF”) tags operate between 860 MHz to 960 MHz, and can transmit data faster and farther—15 to 30 feet—than either HF or LF tags. UHF tag signals may however be absorbed or dissipated in high moisture or water environments. Finally, microwave tags operate at about 5.8 GHz, have high transfer rates, and can be read from as far as 30 feet. However, such tags require substantial power sources and are costly. Accordingly, in preferred exemplary embodiments, HF to UHF RFID readers and tags should provide sufficient range to interrogate and receive a return signal as operated in the anticipated environments. Finally, those skilled in the art realize that the size of the tag antenna may impact read range, such that if the antenna is reduced in size, the read range similarly will be reduced. As such, as antenna technology evolves and improves, LF or HF RFID readers and tags may provide ample read range for the anticipated control applications. 
         [0036]    As further shown in  FIGS. 1A and 1B , the control device/glove  10  would have a plurality of intuitive control or activation points with passive RFID tags  30  embedded at some of those locations or points, to control the motor  100 . More particularly, as illustrated in  FIGS. 1A and 1B , a passive tag  31  would be located at the tip of the glove&#39;s  10  index finger (shown with an encircled “+” sign at the end of the index finger), and would be used to increase motor speed. Similarly, a passive tag  32  would be located at the tip of the glove&#39;s  10  little finger (shown with an encircled “−” sign at the end of the little finger), and would be used to decrease motor speed. Further, a passive tag  33  would be located in the palm area of the glove  10  (shown with a “STOP” sign on the palm area of the glove), and would be used to stop the motor. 
         [0037]    In operation, in an exemplary embodiment, to increase the speed of the motor, the user/athlete  90  would simply touch the tip of his or her thumb  40  to the tip of his or her index finger to activate the increase speed passive tag  31 . To decrease the motor speed, the user/athlete would touch the tip of his or her thumb  40  to the tip of his or her little finger to activate the decrease speed passive tag  32 . Finally, to signal a motor stop, the user  90  need only touch the tip of his or her ring or middle finger against the palm section of his or her hand to activate the stop motor passive tag  33 . 
         [0038]    More specifically, the passive RFID tags  31 ,  32 , and  33  are located in distinct areas or sections of the device or glove, such that touching the thumb and index finger activates the increase speed RFID tag  31  so that as reader  50  polls the passive tag, the tag responds and provides an ID signal to increase the motor speed. Similarly touching the thumb and little finger activates a different RFID tag (to decrease motor speed) so that as the reader  50  polls the passive tag  32 , the tag responds and provides an ID signal to decrease the motor speed. In the same manner, touching the ring or middle finger of the user&#39;s hand to the palm of the glove activates a different RFID passive tag (to stop the motor) so that as the reader  50  polls the passive tag  33 , the tag generates and provides an ID signal to stop the motor. While  FIGS. 1A and 1B  show a left and right glove  10 , it is expected that the user or athlete  90  would only wear one glove  10 . 
         [0039]    In an exemplary embodiment, using the described passive RFID tags  30 , the control inputs operate as follows. An RFID reader or receiver  50  is located in close proximity to the user  90 . For a treadmill, the reader  50  could be near or in the front display panel. Alternatively, the reader  50  could be positioned in the front of the treadmill proximate to the motor  100 . For a swim spa, as specifically illustrated in  FIG. 2 , the RFID reader  50  could be located near the front of the spa/pool and within 2 to 6 feet of head of the swimmer. In either of these embodiments, the location of the RFID reader  50  is such that the user&#39;s hand with the glove  10  is at some points during the exercise motion, within the range or zone  60  through which the RFID reader signals  51  are projected from the reader  50  so that the reader  50  is able to interrogate the passive tags  31 ,  32 , and  33  during the athlete&#39;s exercise routine swimming against the current  103 . 
         [0040]    More particularly, as the athlete&#39;s hand and glove  10  enters the RFID reader read zone  60 , if the user/athlete has not activated either the increase speed  31 , decrease speed  32 , or motor stop  33  passive tags, then the reader interrogation of the passive tags results in no signal being generated by any of the passive tags  30 , and no signal is sent back to the receiver  50 . Accordingly, no signal would be sent by the receiver  50  to the motor  100  or motor controller  120 . 
         [0041]    If however, the swimmer/athlete  90  has activated either the increase speed  31 , decrease speed  32 , or motor stop  33  tag signal, by either touching his or her thumb to his or her index finger (to increase speed), or touching his or her thumb to his or her little finger (to decrease speed), or touching his or her ring and/or middle fingers to the palm of the gloved hand (to signal a motor stop), then the reader  50  interrogation of the passive tags  30  results in the activated passive tag generating a return identification signal that is sent back to the reader  50 . The RFID reader  50  accordingly receives the respective passive tag signal (increase speed, decrease speed, or motor stop), and, as shown in the  FIG. 3  block diagram, transmits that respective signal in turn to a decoder  330 , the motor controller  350 , the motor driver  360 , and finally to the motor  100  to either increase or decrease speed, or stop the motor  100 . 
         [0042]    An example of the above described controllable passive RFID tags are described in further detail in  A Capacitive Touch Interface for Passive RFID Tags  as presented at the 2009 IEEE International Conference on RFID, and published in the conference proceedings as pages  103  to  109 , which such pages are incorporated herein by reference. 
         [0043]    In other embodiments, as suggested above, instead of passive RFID tags  30 , active RFID tags having a power source could alternatively be used in the glove  10 . Similarly, other RF or IR circuits and signal generators, again with an appropriate power source in the glove, could likewise be used as an alternative to the passive tags. Finally, other wireless signal generators could be used to create the motor control signals, however, such signal generators would probably need to have a power source in the glove  10 . While such systems could be manufactured, they may not be suitable for certain water immersed embodiments of the invention, because of the need for a power source within the glove  10 . 
         [0044]    Because in the above disclosed exemplary embodiment, only the thumb, index finger, little finger, and palm area of the user&#39;s hand are used for control inputs, a partial or cutaway glove  10 , such as illustrated in  FIG. 1B , may be used, and thereby provide the user with substantial sections of his or her hand that are open to the air or water. With such sections of the glove  10  removed, the user is able to sense the outside environment, be it air or water or a solid object (such as a touch screen), through the parts of the user&#39;s hand that are not covered by the glove  10 . Other different variants of cut-away gloves can be used and are equally effective as a control device  10 , including having a cut-away for the thumb of the user (not shown), and still provide the user with the ability to have direct sensation of the outside environment with the part of his or her hand that is not covered by the glove  10 . 
         [0045]    In further detail, the method and operation of the device and system, in an exemplary embodiment, is illustrated in the  FIG. 3  block diagram. As shown, when the user activates one of the passive RFID tags  31 ,  32 , and  33  incorporated into the glove  10 , the respective passive tag signal  39 , to either increase speed, decrease speed, or stop the motor, each as described above with reference to  FIGS. 1A ,  1 B, and  2 , is able to be activated and read by the RFID reader/receiver  50 . When that passive tag  30  signal  39  is read by the reader  50 , the signal is wirelessly transmitted  320  to the RF receiver  50 . The respective signal is then decoded  330  after receipt by the RF receiver  50 , and is then transmitted  340  to the motor controller  350 . The motor controller  350  then passes  360  the respective control signal to the motor driver  370 , which in turn controls the motor speed based upon the RF signal input  39 . Specifically, an increase speed signal increases the motor speed; a decrease speed signal decreases the motor speed; and a stop motor signal stops the motor  100 . 
         [0046]    In one exemplary embodiment of the operation of the remote control system, so long as the user&#39;s thumb and index finger are touching, the RFID passive tag  31  is activated and an increase speed signal (transmitted to the motor controller  350 ) will remain, thereby instructing the controller  350  to continue to increase the speed of the motor  100 . Similarly, as long as the user&#39;s thumb and little finger are touching and the RFID decrease speed passive tag  32  is activated, the signal to the motor controller  350  to decrease the motor speed will continuously decrease the motor speed. 
         [0047]    In an alternative embodiment, providing for discrete step control, upon the user touching his or her thumb tip with his or her index finger tip, a single increase motor speed signal is generated by the passive tag  31  and sensed by the reader  50 . To increase the motor speed further would require the user to release his or her thumb and index finger, and then retouch his or her thumb and index finger. Accordingly, in this manner and embodiment, the user has the ability to increase or decrease the motor speed in discrete increments. With appropriate calibration of the single signal sent from the RFID passive tags  30  as applied to the motor controller  350 , the glove control device  10  can be used to increase or decrease the exercise exertion by a specific amount, for example, by 0.1 miles per hour. With differing calibration, the incremental increase or decrease could be a larger or smaller amount. Such calibration could be set when the glove  10  and motor controller  350  are manufactured, or in an alternative embodiment, the calibration, or amount of speed increase or decrease with each activation of an RFID signal could be set and varied by the end-user. 
         [0048]    While the microchip within the passive tag typically carries a limited amount of data, usually a maximum of 2 KB of data, such amount of data is more than adequate to store basic information required about the tag, including in the exemplary embodiments, whether the RFID tag  30  is to increase motor speed, decrease motor speed, or provide for a full motor stop. Moreover, some RFID tags have chips with read-only capabilities, with information stored on the tag during manufacturing that cannot be revised or updated. Still other tags have chips that have read-write functionality, thereby allowing data to be modified or updated from time to time. Such latter tags and chips could be used for calibration of the discrete increase/decrease motor speed increments. 
         [0049]    In a further exemplary embodiment of the inventive system, as shown in  FIG. 4 , a computer processor  500  with associated data memory  510  is communicatively connected to the motor controller  350 . The computer processor  500  records and saves to the data memory  550  a time history of the motor controller signals as a function of time, illustrated in  FIG. 4  next to the memory  510 . In other words, the computer processor  500  records and saves a time history record of the controller speed input to the motor driver  360 . The data memory  510  of the computer processor  500  can be sized to record multiple time histories of the motor speed. Where multiple time histories are stored, the computer processor  50  automatically saves each time history file under a unique file identifier. In a preferred embodiment, the user is able to recall and rename any of the recorded and saved time histories, thereby making it easier to recall any particular desired recorded motor speed time history. 
         [0050]    By saving or recording a time history of the motor speed control, the user can later recall the recorded time history, and select to drive the motor using the recorded time history. This allows the athlete/user  90  to repeat the same exertion level as a function of time, and thereby monitor his or her performance at different times, or on different days. 
         [0051]    As shown in the  FIG. 5  block diagram, for the embodiment allowing the motor to be controlled by a recorded and saved time history, a switch  400  is implemented to take input from either the RF decoder  330  or the output from the computer processor  500  depending upon whether the user  90  desires to directly control the motor speed, or have a prior recorded time history control the motor speed. Based upon the user&#39;s decision, the switch  400  is either set to transmit direct control input from the user  90  (through the RF reader  50  and decoder  330 ), or to transmit the previously recorded time history to the motor controller  350  from the computer processor  500 . In this fashion, as described above, the user or athlete  90  can “replay” a previously recorded motor speed profile to repeat exercise against, and thereby monitor his or her fitness level at different times. 
         [0052]    In a further exemplary embodiment, as illustrated in  FIG. 5 , the recorded time history could be transmitted by the computer processor  500  to a remote electronic device  570 , such as a smartphone that can undertake various analytics, such as comparison to prior exercise routines, or simply provide information that can be transmitted through social media. 
         [0053]    By way of example, the above described embodiment having a computer processor  500  and associated memory  510 , could be used for physical rehabilitation to allow the user and/or physical therapist to monitor and measure improvement or degradation of rehabilitation or an injury based upon the patient&#39;s repeat of a recorded exertion time history. Alternatively, the described embodiment could be used by swim instructors or swim teams, such as swim clubs, colleges, or Olympic training facilities, to monitor an athlete&#39;s training as a function of time. 
         [0054]    In a further enhancement and preferred embodiment to the inventive system, the glove device  10  could also comprise a stopwatch activated by touching a start/stop (shown with a “s/s” label) location  61  on the glove  10 , as shown in  FIG. 6A , being near the wrist of the user&#39;s glove  10  so as not to be confused with the motor increase or decrease signals at the finger tips. The stopwatch would allow the user to record the duration or length of time of the exercise. A lap function  62  could also be included on the glove  10 , as shown in  FIG. 6A , to allow the athlete to record the time for particular laps or segments of the exercise. The lap activation tag  62  is shown in an exemplary embodiment near the middle section of the user&#39;s middle finger to ensure it is not inadvertently activated or confused with the increase or decrease motor speed tags. Other locations for the lap tag could be used on the glove  10 . The stopwatch output would be readable by the athlete  90 , or displayed to the athlete, from a separate device, as described below. In an alternative embodiment, the stopwatch readout could be included as a digital readout  67 , as shown in  FIG. 6B , located on the back section of the glove  10  near the wrist area of the glove. 
         [0055]    Additional features that may be included with the glove control system are a swim stroke counter, and/or a heartrate monitor. The stroke counter would work through at least one accelerometer  70  embedded in the glove  10 . The accelerometer  70  in the glove  10  senses the rotation of the swimmer&#39;s arm and hand as the swimmer lifts his or her arm over his head to start the swim stroke and then pulls his or her arm back through the water to the starting position. The accelerometer/stroke count data can be transmitted to the computer processor  500 , for later read out, or can be displayed to the swimmer through various means as described below. Such display means could also be a digital readout located in the wrist region of the glove, or on the back of the glove, similar to the stopwatch display, as illustrated in  FIG. 6B . 
         [0056]    The swimmer&#39;s heartrate could also be sensed by measuring the blood flow and a pulse from the wearer&#39;s thumb or wrist area. In alternative embodiments, the swimmer&#39;s heart rate can be determined by sensing blood flow and pulse from one or more of the wearer&#39;s fingers, using, in one embodiment, optical sensors. Similar to the swim stroke data, the heartrate data can be transmitted to the computer processor  500  for recording and later readout. Alternatively, the heartrate data can be displayed directly to the swimmer through various display means such as, similar to as described above, a digital readout located in the wrist region of the glove  10 , or on the back of the glove. With the potential for multiple data readouts, such as elapsed time, swim stroke, and/or heartrate, in an exemplary embodiment, a single display  67  could be incorporated in the glove  10 , such as shown in  FIG. 6B , and the data to be displayed could be cycled through as a function of time. In such an embodiment, the display for each data output could be shown for approximately 2 to 3 seconds, before the next data output is shown. The athlete  90  could then see the respective data output for elapsed time, swim stroke, and/or heartrate by viewing the same display on the back of the glove  10 . 
         [0057]    In still a further enhancement and providing an additional element and feature to the glove control system where used in a swim spa setting, the data measured at the glove, along with separately measured data, such as current speed, can be displayed on a mirror  710  positioned at the front of the pool, such that it can be easily observed and read by the swimmer  90  during the swim exercise. In an exemplary embodiment of the mirror display,  FIG. 7  shows how the data can be shown without impairing the swimmer&#39;s view of his or her image in the mirror  710 . The mirror  710  essentially becomes the equivalent of a heads-up display allowing the swimmer  90  to monitor various sensed data, in real-time, including without limitation, current/swim speed, duration of exercise, total distance or laps completed, average stroke rate per lap, average stroke rate per minute, total strokes, and heartrate where such data is being monitored or sensed. 
         [0058]    In still a further preferred embodiment, the information transmitted to the mirror  710 , as described above, could also or alternatively be displayed on the swimmer&#39;s goggles  810  as a heads-up-display (“HUD”). An exemplary illustration of such display in a pair of swimmer&#39;s goggles is shown in  FIG. 8 . Wireless methods and systems for displaying information on swimmer&#39;s goggles have been described in U.S. Pat. No. 4,796,987 for a Digital Display For Head Mounted Protection, and U.S. Pat. No. 7,185,983 for a System and Method For Displaying Information On Athletic Eyewear which are both incorporated by reference herein. 
         [0059]    While various preferred embodiments have been disclosed herein showing use of a glove to remotely control a swim spa current motor, in another preferred embodiments, the remote control device could be used to control other types of motors, including for example, for treadmills, a crane or other types of lift or movement motors. As disclosed, while the various exemplary embodiments show use of passive RFID technology and signals to control the motor, in other embodiments of the inventive system and method, other wireless technologies could be used, such as active RFID, RF, IR, NFC, or other wireless signals. 
         [0060]    The above detailed description teaches certain preferred embodiments for the present inventive remote control device, system and method to control motor speed. While preferred embodiments have been described and disclosed, it will be recognized by those skilled in the art that modifications and/or substitutions are possible and such modifications and substitutions are within the true scope and spirit of the present invention. It is likewise understood that the attached claims are intended to cover all such modifications and/or substitutions.
