Abstract:
The present invention is directed to systems and methods for providing exercise devices with motivational programming. The programming includes motivational content and control signals, synchronized with the motivational content, for controlling operation of the exercise device. The motivational content preferably includes audio and/or video designed to simulate a group exercise setting and optionally instructional and educational content for the benefit of the user. The control signals can be carried in a carrier signals and can include bytes of data that define changes to the value of one or more operating parameters of an exercise device. The control signals can be audible to a listener and therefore act as an audible warning of upcoming changes in the one or more operating parameters of the exercise device.

Description:
RELATED APPLICATION  
       [0001]    This is a continuation application of U.S. patent application Ser. No. 09/349,608, filed Jul. 8, 1999, entitled “Systems and Methods for Providing an Improved Exercise Device with Motivational Programming,” the disclosure of which is incorporated herein by this reference. 
     
    
     
       BACKGROUND OF THE INVENTION  
         [0002]    This invention relates to exercise equipment and, more specifically, to systems and methods for providing improved exercise devices in combination with motivational programming.  
           [0003]    In an attempt to improve their health and physical conditioning, consumers are purchasing home exercise devices in record quantities. One common problem with home exercise equipment is motivating the purchaser to use the device on a consistent and ongoing basis. In addition, many exercise devices involve repetitive actions, which can quickly become tedious and boring to a person exercising alone.  
           [0004]    In recent years, health clubs have organized various exercise classes and routines involving a group setting. In the proper setting, a group approach to exercise creates a synergy, whereby individual members of the class derive encouragement and motivation from other members of the group. In addition, group settings promote a healthy sense of competition among group members. Initially, such group fitness and exercise classes typically involved aerobics, traditionally performed without the use of any ancillary exercise equipment or devices. In recent years, however, the group work out approach has been extended to classes that utilize various exercise devices. Take, for example, the recent rise in popularity of “Spinning Classes,” in which each participant operates his or her own stationery exercise cycle in a group setting, with a coach or instructor leading the group through a prescribed program or routine. Similarly, with recent advances in the design of treadmills, it is possible to have “Treadmill Classes” wherein an instructor not only leads and motivates the group, but the instructor is also able to control the operation of the treadmills of all of the class participants from a single control panel.  
           [0005]    One of the primary disadvantages with group training, however, is that it is typically available only at health clubs and, therefore, is not as convenient as exercising in the privacy and comfort of one&#39;s own home. It would, therefore, be a definite advancement in the art of home exercise equipment to provide the desirable benefits of group exercise by providing motivational, interactive programming that simulates a group exercise setting in the home.  
           [0006]    Some efforts have been made in the prior art to introduce a level of “interactivity” into exercise machines. For example, U.S. Pat. No. 5,489,249 discloses a video exercise control system in which a video cassette recorder or similar device is coupled, via a hard wired connection, to an exercise machine, such as a treadmill, and wherein the speed and inclination of the treadmill are controlled by the VCR in synchronization with prerecorded audiovideo presentations. U.S. Pat. No. 5,645,509 discloses a remote exercise control system in which an exercise machine, such as a treadmill, which includes a control console that communicates via a communications module with an evaluation module located at a remote location. Signals indicative of the operating parameters of the treadmill are transmitted from the treadmill to the evaluation module, and control signals are transmitted from the remote evaluation module for controlling the operating parameters of the treadmill. U.S. Pat. No. 5,888,172 is representative of another approach found in the prior art, wherein an exercise device is coupled, via hard wired connection, to a video game device, such that the operating parameters of the exercise device are used as inputs to the video game controller, which then produces a motivational video display based on the inputs received. These approaches, however, do not facilitate live, interactive communications between a treadmill user at home and a trainer or coach in a remote location, which allow the trainer or coach to control the operating parameters of the user&#39;s treadmill on a real time basis.  
         BRIEF SUMMARY OF THE INVENTION  
         [0007]    The present invention is directed to systems and methods for providing exercise devices with motivational programming. The present invention is particularly well suited to exercise devices that utilize one or more motors and/or other electrically driven actuators that control one or more operating parameters of the exercise device. The present invention contemplates the use of programming that includes motivational content and one or more control signals, synchronized with the motivational content, for controlling operation of the exercise device. The motivational content preferably includes audio and/or video designed to simulate a group exercise setting. In addition, the motivational content can include instructional and educational content for the benefit of the user. The programming can be live or prerecorded and can be broadcast over conventional broadcast channels, cable, satellite, the internet or any other means suitable for transmitting audio and/or video signals. Alternatively, the programming can be prerecorded and stored on a storage medium, such as audio cassette tapes, compact discs, mini-discs, videotapes, laser discs, digital video discs, computer diskettes or any other storage medium suitable for the storage and reproduction of audio and/or video signals. The present invention also includes means for reproducing the programming, including the motivational content along with the synchronized control signals. Finally, the present invention includes means for decoding the control signals and for controlling the operation of the exercise device in synchronization with the motivational content.  
           [0008]    Accordingly, an object of the invention is to provide exercise devices that incorporate a standardized interface for receiving and decoding control signals embedded in multimedia (i.e., audio and/or video) programming for controlling various operating parameters of the exercise device in synchronization with the multimedia programming.  
           [0009]    Another object of the present invention is to improve home exercise equipment by providing home exercise devices that are capable of simulating a group or class workout environment and synchronizing operation of the exercises devices with motivational programming.  
           [0010]    Another object of the invention is to provide improved exercise devices, wherein programming containing motivational content and control signals can be reproduced using audio and/or video playback devices commonly found in the home, such as televisions, VCRs, home stereo equipment and the like, and the exercise device can decode and utilize the control signals to synchronize operation of the exercise device with the motivational content.  
           [0011]    It is another object of the invention to provide exercise devices that are responsive to control signals that are encoded in programming external to the exercise device and containing audio and/or video and that can be transmitted and received by conventional broadcasting technologies.  
           [0012]    Yet another object of the invention is to provide enhanced exercise devices, the operation of which can be controlled using interchangeable, multimedia programming containing motivational content and control signals that are synchronized with the motivational content.  
           [0013]    Yet another object of the invention is to provide an improved exercise machine that facilitates live, interactive communications between a treadmill user at home and a trainer or coach in a remote location, and which allows the trainer or coach to control the operating parameters of the user&#39;s treadmill on a live, real time basis.  
           [0014]    These advantages in addition to other objects and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by the practice of the invention. The objects and advantages of the invention may be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0023]    The present invention is directed to exercise devices that include one or more motors or other electrically driven actuators used to control one or more operating parameters of the exercise device. While the invention will be described in the context of a motorized treadmill, it should be understood that the invention is not limited to any particular type of exercise device. To the contrary, the present invention can be readily adapted to any motorized exercise device or any other exercise device that utilizes stepper motors, solenoids or any other electrically driven actuator to control any operating parameter of the device, such as speed, resistance, inclination or other similar operating parameters. As used herein, the term “exercise devices” shall refer broadly to any type of exercise machine, including, but not limited to, treadmills, exercise cycles, nordic style ski exercise devices, rowers, steppers, and elliptical or striding exercise devices.  
         [0024]    Referring now to FIGS. 1 through 4 generally, which depict a typical motorized, reorienting treadmill  10 . Treadmill  10  includes a control panel  12  supported on a generally upright support structure  14  and a tread base  16 . The tread base  16  typically consists of a pair of side rails  18  and  20 , a front pulley  22  and a rear pulley  24  disposed between and supported by the side rails  18  and  20 , and a continuous belt  26  extending between and around front and rear pulleys  22  and  24 . A wooden deck  28  typically supports the upper run of belt  26 . As best seen in FIG. 3, front pulley  22  is mechanically coupled to an electric tread drive motor  30  by means of pulleys  32  and  34  and a drive belt  36 . Motor  30  also incorporates an inertial flywheel  38  and is electrically coupled to a treadmill controller  40 . The operation of motor  30 , and thus the speed of belt  26 , is controlled by treadmill controller  40 , either in response to direct input by the user through various input devices  42  (e.g., switches, rheostats, etc.) located on control panel  12  or in response to programming stored in nonvolatile memory incorporated into treadmill controller  40 . Visual indicators relating to the operational status of treadmill  10 , such as speed, inclination, duration of the work out, etc., are provided to the user through one or more output devices  44  located on control panel  12 . Typical output devices  44  include LED displays and/or LCD displays.  
         [0025]    In addition to the ability to control and vary the speed of belt  26 , treadmill  10  also permits the degree of inclination of tread base  16  relative to the floor to be varied. Typically, this is accomplished through the use of an inclination drive motor that raises or lowers one end of tread base  16  relative to the other end. In the embodiment illustrated in FIGS. 1 through 4, a pair of rear feet  46  and  48  are rotatably attached to the rear of portion of side rails  18  and  20 . As best seen in FIGS. 3 and 4, feet  46  and  48  are also mechanically coupled through a shaft  50  to an inclination drive motor  52 , which causes feet  46  and  48  to pivot about their points of pivotal attachment to side rails  18  and  20 , thereby selectively raising or lowering the rear end of tread base  16  relative to the front end thereof. Motor  52  is also electrically coupled to, and controlled by the treadmill controller  40 , either in response to direct user input through the input devices  42  located on control panel  12  or to programming stored in nonvolatile memory incorporated into treadmill controller  40 .  
         [0026]    Again, neither the particular exercise device nor the particular design of a given exercise device is intended to limit the scope of the present invention. Rather, the present invention has broad application for any number of exercise devices.  
         [0027]    In the present invention, programming is used that contains both motivational content and one or more control signals. The control signals are synchronized with the motivational content and are designed to control one or more operating parameters of the exercise device, such as treadmill  10 , in synchronization with the motivational content of the programming. As used herein, the term “motivational content” is used to broadly refer to any audio material, including dialog, narration, sound effects and/or music, either alone or in combination with video material. In one presently preferred embodiment of the present invention, the motivational content consists of an audio/video presentation of a personal trainer and others engaged in a series of exercises of varying difficulty using treadmills. The motivational content includes voice-overs by the trainer, consisting of dialog designed to instruct and encourage the user of treadmill  10 , and accompanying background music. The tone and tempo of both the dialog and the background music is selected to match the intensity of the workout. While the foregoing selections are provided by way of example, it should be understood that the selection of the particular audio and video used to motivate and inspire the user of treadmill  10  is virtually limitless and is left to the imagination of the producer of the motivational content.  
         [0028]    As mentioned above, the programming also contains control signals for controlling one or more operational parameters of the exercise device. In the case of treadmill  10 , the programming includes control signals that control the speed of belt  28 , as well as signals that control the degree of inclination of tread base  16 . Furthermore, the control signals are synchronized with the motivational programming such that the intensity of the operation of treadmill  10  coincides with the intensity of the motivational content of the programming, and vice versa.  
         [0029]    The programming may be either performed live or prerecorded. Whether live or prerecorded, programming incorporating audio and video can be transmitted via existing broadcast technology, including television broadcast over the airwaves, via cable, via satellite, via telephone lines, via the internet or any other suitable transmission technology or medium. Similarly, programming containing only audio can be transmitted via existing radio broadcast technology, including over the airwaves, via cable, via satellite, via telephone lines, via the internet or any other suitable transmission technology or medium. In this way, the present invention is compatible with existing conventional broadcast technologies and can interface with existing audio and/or video components commonly found in homes, thereby reducing the overall cost of the exercise device.  
         [0030]    The programming may also be prerecorded and stored on a suitable storage medium. Any form of storage medium that is suitable for storing audio and/or video signals or data can be used and is within the scope of the present invention. For example, programming that contains only audio can be stored on audio cassette tapes, compact discs (CDs), mini-discs (MDs), computer diskettes or any other storage media suitable for storing audio programming. Similarly, programming that contains both audio and video can be stored on videotapes, laser discs (LDs), digital video discs (DVDs), computer diskettes or any other storage media suitable for storing audiovideo programming.  
         [0031]    The present invention also includes means for reproducing the programming. The particular reproducing means is selected based on either the manner in which the programming is transmitted (e.g., television or radio signals) or the storage media on which the programming is stored (e.g., tape player for audio tape, CD player for CDs, MD player for MDs, VCR for videotapes, LD player for LDs, DVD player for DVDs, personal computer for computer diskettes, etc.). In addition, the reproducing means can either be separate and distinct from treadmill  10  (as reflected in FIGS. 5 and 6) or, alternatively, the reproducing means can be integrated into treadmill  10  itself (as reflected in FIG. 7). The advantage with the former is that it enables treadmill  10  to interface and operate with existing audio and/or video components (e.g., televisions, home stereos, computers, etc.) that may already be found in the home and does not significantly increase the cost of treadmill  10 .  
         [0032]    The present invention also includes means, responsive to the control signals, for controlling the operation of treadmill  10 . Where the reproducing means is separate and distinct from treadmill  10  (FIGS. 5 and 6), the control means comprises sensor means for sensing and converting the audio portion of the reproduced programming to an electrical signal, means for decoding said control signals, and means for driving said one or more motors or other electrically driven actuators in response to the decoded control signal. In one presently preferred embodiment, the sensor means is preferably a condenser microphone incorporated into the control panel  12  of treadmill  10 . As the programming is reproduced by the reproducing means, the condenser microphone picks up the audio portion of the programming and converts or transforms the audio portion of the programming back into an electric signal. The output of the microphone is electrically coupled to decoder circuitry, which detects, separates out the control signals from the rest of the programming and interprets or decodes the control signals. The driving means, which is electrically coupled to the output of the decoder circuitry, drives the appropriate motors or actuators of treadmill  10  in response to the control signals received through the microphone as part of the programming. For example, when the tempo of the motivational content increases, the programming will contain a control signal to increase the speed of main motor  26  which, in turn, increases the speed of belt  36 . As discussed in more detail below, the control signals are superimposed on the audio signal of the motivational content and are picked up by the microphone. The decoder circuitry then distinguishes between the control signal and the audio portion of the motivational content (i.e., dialog, sound effects, music), interprets the control signals and then provides the appropriate control signals to the appropriate motor or actuator of treadmill  10 . Where the reproducing means is integrated into treadmill  10  (FIG. 7), a sensor means or microphone is not required. Instead, the output of the reproducing means is directly, electrically coupled to the decoder circuitry.  
         [0033]    The presently preferred format for encoding the control signals will now be discussed. It should again be understood that the method of encoding set forth below is representative only and is not intended to limit the scope of this invention. Any number of encoding schemes, which are known to those skilled in the art, could be used to carry out, and are encompassed within, the scope of the present invention. In one presently preferred embodiment, the control signals are carried on a  2  kHz carrier signal, with each control signal consisting of two transmission bursts, each burst having three bytes of data. The second burst is intended to exactly duplicate the first burst for error checking purposes. The first byte of data of each burst indicates the desired speed of the treadmill, the second byte of data indicates the desired inclination of the tread base  16 , and the third byte is a checksum of the first and second bytes. The control signals also preferably use standard RS232 protocol. Each control signal, including both bursts, is typically less than one-quarter second in duration. Each byte consists of 8 bits of data, giving a high degree of resolution for controlling treadmill speed and the degree of inclination. In one presently preferred embodiment, each time a control signal is inserted into the programming, the control signal entirely suppresses the audio portion of the motivational content for the duration of the control signal. As a result, the control signals are audible to the user, which also provides an audible cue or warning to the user that one or more operating parameters of treadmill  10  is about to change.  
         [0034]    As alluded to above, the control signals are detected and decoded by a control signal decoder, which verifies that the control signal has the proper 2 kHz carrier frequency, checks to make sure that the control signal is otherwise properly formatted, and checks for errors. The decoder then passes the appropriate control signals to the processor, which in turn controls the appropriate operating parameters of the treadmill.  
         [0035]    Reference is now made to FIG. 5, which is a functional block diagram of one presently preferred embodiment of the invention, wherein the programming is transmitted from a location remote from the treadmill  10 . As alluded to above, the invention comprises means for reproducing the programming and means responsive to control signals encoded in the programming for controlling one or more operating parameters of treadmill  10  in synchronization with the motivational content of the programming. In the embodiment illustrated in FIG. 5, the structure corresponding to the reproducing means consists of conventional broadcast transmission equipment  54  in combination with a conventional audio and/or video receiver and playback device  56 . Where, for example, the programming is transmitted via a television signal, receiver and playback device  56  may comprise a conventional television. Where the programming is transmitted via a radio signal, receiver and playback device  56  may comprise a conventional radio or home stereo receiver. In any event, the audio portion of the programming is reproduced by receiver and playback device  56  through a speaker  58 . The video portion, if any, of the programming is displayed by receiver and playback device  56  through a suitable video display  60 , such as a CRT, LCD or other similar device suitable for displaying video.  
         [0036]    The invention also comprises means, responsive to control signals encoded in the programming, for controlling one or more operating parameters of treadmill  10  in synchronization with the motivational content of the programming, which comprises (i) sensor means for sensing and converting the audio portion of the reproduced programming into an electrical signal, (ii) means for decoding the control signals, and (iii) means for driving one or more operating parameters of the exercise device in response to the decoded control signals. In the embodiment illustrated in FIG. 5, the structure corresponding the sensor means comprises a microphone  62 , which is integrated into the treadmills  10 , preferably as part of the control panel  12 . Microphone  62  receives the reproduced programming in the form of acoustic sound waves produced by speaker  58  and converts the received acoustic signals into an electric signal. The output of microphone  62  is received by control signal decoder circuit  64 , which comprises the means for decoding the control signals. As discussed previously, decoder circuit  64  detects and identifies properly formatted control signals by checking for the proper  2  kHz carrier frequency and checking for errors by comparing the values of the first two bytes against the checksum contained in the third byte. Once decoder circuit confirms that a properly formatted control signal has been received, it then breaks down the control signal and separates out the speed control portion contained in the first byte from the inclination control portion contained in the second byte and passes the appropriate control signals to processor  66 , which in turn adjusts the speed of tread motor  30  and/or the position of inclination motor  48  as dictated by the received control signal.  
         [0037]    Reference is now made to FIG. 6, which is a functional block diagram illustrating another presently preferred embodiment of the invention. The embodiment of FIG. 6 differs from that illustrated in FIG. 5 only in that it is intended to be used with programming that is stored on a player-readable storage medium, as opposed to be transmitted from a remote location via conventional broadcast channels. In this embodiment, the playback device  56  is selected based on the type of storage media on which the programming is recorded or otherwise stored. In all other material respects, the embodiment illustrated in FIG. 6 functions essentially the same as the embodiment illustrated in FIG. 5.  
         [0038]    While the embodiments illustrated in FIGS. 5 and 6 both contemplate the use of a speaker and microphone as the presently preferred means of transferring the audio portion of the programming between receiver and playback device  56  and treadmill  10 , it should be understood that other devices could readily be used to perform the same function. For example, an RF transmitter connected to receiver and playback device  56  and a compatible RF receiver connected to treadmill  10  could be used in place of speaker  58  and microphone  62 . Similarly, an infrared transmitter and compatible infrared receiver could also be used to accomplish the same function.  
         [0039]    Referring now to FIG. 7, which is a functional block diagram of yet another presently preferred embodiment of the invention. In this embodiment, playback device  56  is incorporated into treadmill  10 , thereby eliminating the need for separate audio and/or video equipment. Where in the programming comprises only audio, playback device  56  preferably comprises an audio cassette player, a CD player, a MD player or other suitable audio playback device that is compatible with the format on which the programming is recorded or otherwise stored. Similarly, if the programming includes both audio and video, playback device  56  preferably comprises a display suitable for displaying video images in combination with either a video cassette player, a DVD player or a LD player. Preferably, the speakers  58  and/or video display  60  of the playback device  56  are incorporated into control panel  12  of treadmill  10 .  
         [0040]    The embodiment illustrated in FIG. 7 differs from the embodiments illustrated in FIGS. 5 and 6 in that it does not require the use of a separate sensor for sensing and converting the reproduced audio portion of the programming. Rather, the output of playback device is coupled not only to speaker  58  and/or video display  60 , but is also electrically coupled to the input of control signal decoder circuit  64 . In all other material respects, the embodiment illustrated in FIG. 7 functions essentially the same as the embodiment illustrated in FIG. 5.  
         [0041]    Yet another embodiment of the present invention facilitates true interactive communications between a user, operating an exercise device in his or her own home, and a trainer or coach located at a remote location, wherein the trainer or coach can observe the user and control the user&#39;s exercise device remotely. In this embodiment, the exercise device incorporates a microphone, a video camera, a processor means, and a communications module, such as a modem. At the user&#39;s location, audio data is captured by the microphone and video data is captured by the video camera, which is then processed by the processor means by known methods. The exercise device is also preferably equipped with various sensors that detect the operating parameters of the exercise device, such as belt speed, degree of inclination, etc., and from which outputs are derived that are indicative of the present operating state of the exercise device at any given point in time. The audio, video and operating parameter data is then transmitted to the remote location for reproduction, viewing and monitoring by the trainer/coach at the remote location with minimal delays. In this embodiment, the preferred data transmission medium is a telephone line and a global computer network, such as the Internet. The invention is, however, not limited to the specific transmission medium, but may easily be adapted to other transmission media.  
         [0042]    Similarly, audio and video data of the trainer/coach is captured and processed at the remote location and transmitted to the user for reproduction and viewing by the user with minimal delays. In addition, the trainer/coach is able to transmit control signals, encoded in the manner discussed above, to control, in real time, various operating parameters of the user&#39;s exercise device. In this manner, the exercise device of the present invention facilitates true interactive communications between a user exercising in his or her own home and a trainer/coach located in a remote location and control of the exercise device by the trainer/coach from the remote location.  
         [0043]    The present invention is also directed to improved methods of operating an exercise device consistent with the teachings set forth above. In accordance with the present invention, the method includes the steps of (i) producing programming having motivational content and one or more control signals for controlling one or more parameters of an exercise device, (ii) transmitting the programming from a location remote from the exercise device; (iii) receiving and reproducing the transmitted programming; (iv) decoding the control signals, and (v) adjusting operating parameters of the exercise device in response to the decoded control signals such that the operation of the exercise device is synchronized with said motivation content. The actions corresponding to each of the foregoing steps are the same as and consistent with the teachings directed to apparatus discussed in detail above.  
         [0044]    From the foregoing description, it will be apparent that the present invention provides advantages and features not previously found in the prior art. For example, the present invention provides exercise devices that incorporate a standardized interface for receiving and decoding control signals embedded in multimedia programming for controlling various operating parameters of the exercise device in synchronization with the multimedia programming. In addition, the present invention provides home exercise devices that are capable of simulating a group or class workout environment and synchronizing operation of the exercises devices with motivational programming. The present invention also provides improved exercise devices, wherein programming containing motivational content and control signals can be reproduced using audio and/or video playback devices commonly found in the home, such as televisions, VCRs, home stereo equipment and the like, and the exercise device can decode and utilize the control signals to synchronize operation of the exercise device with the motivational content. The present invention facilitates the use of interchangeable, multimedia programming that is external to the exercise device itself, making it possible to quickly and easily “program” the exercise device to perform an endless variety of exercise routines, accompanied by motivational content which is limited only be the imagination of producers of multimedia programming. The present invention also provides flexibility, in that the multimedia programming may be broadcast, either live or at a later time, from a location remote from the location of the exercise device or, alternatively, the multimedia programming can be recorded and/or stored on a suitable storage medium and reproduced at the convenience of the user. The present invention also facilitates live, interactive communications between a treadmill user at home and a trainer or coach in a remote location, which allows the trainer or coach to control the operating parameters of the user&#39;s treadmill on a live, real time basis.  
         [0045]    Although preferred embodiments of the invention are described herein in detail, it will be understood by those skilled in the art that variations may be made thereto without departing from the spirit of the invention or the scope of the claims.
