BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to devices which aid differently abled individuals such as those that are hearing-impaired or visually impaired to receive communications. 
     2. Description of the Art Practices 
     U.S. Pat. No. 6,359,550 to Brisebois, et al. Mar. 19, 2002 discusses an array of stimulators associated with a personal communications device for providing the user with tactile messaging respecting call processing or call network status. The array is positioned on the device so as to be in contact with the user while the terminal is carried or worn, on a wrist, for example. The stimulators of the array are activated independently so as to provide the user with an encoded message of call processes such as alerting, dial tone, busy signal, etc. Preferably each status is associated with one of a set of unique patterns of operation of the stimulators recognizable by the user as tactile image or pattern of operation, rather than necessitating tactile sensation of individual sequences of each stimulator. Advantageously audio and haptic signaling is synchronized to provide a tactile warning to alert user to impending audio signal, and thereby allow a lower level, i.e. quieter, audio signal to be used, because the user is primed by the tactile signal to expect the audio signaling. Thus the audio threshold for effective signaling is reduced and obtrusiveness of audio signaling in public places may be reduced when used in combination with tactile messaging. 
     U.S. Pat. No. 6,236,319 issued May 22, 2001 to Pitzer, et al. describes a body worn transmitter periodically transmits a coded RF signal from a rolling code generator, which is received by a base unit at the location where a person is confined, which base unit has a rolling code generator synchronized to produce the same random code signal for comparison. If proper coded signals are not received, a report is sent via telephone to a remote monitoring station. The body worn transmitter is designed to detect and defeat attempts at removal. The body worn transmitter is also used to detect the presence of a person at a particular location. By programming the time of RF transmissions, a large number of body worn transmitters can be monitored at a given location. 
     Kanor, et al. in U.S. Pat. No. 6,384,728 issued May 7, 2002 relates to a personal care monitoring system having at least one condition detecting sensor and a corresponding condition indicator. The condition detecting sensor may indicate detection of wetness, such as caused by enuresis. Alternatively, or additionally, the condition detecting sensor may indicate that the physical position of the wearer of the device has not been adjusted for over a predetermined amount of time after which the likelihood of the development of bedsores increases. The indicator may be any desired type of indicator, preferably alerting one of the senses that the monitored condition has been detected. For instance, the indicator may be a light, an audible alarm, or a vibrating device. A processing means preferably is provided to control operation of the various components of the monitoring system. Moreover, the processing means may be programmed to store information pertaining to the operation of the components of the monitoring system. For example, the time at which a condition has been detected as well as the time at which a care giver has attended to the condition may be recorded. Such information may be retrieved to determine the frequency of care given to the wearer of the monitoring system as well as the amount of time elapsed between occurrence of the monitored condition and attendance to such condition by the care giver. 
     Powell in U.S. Pat. No. 6,118,979 issued Sep. 12, 2000 suggests a method of communicating an incoming call through a telephone receiver having an incoming call circuit and an audible signal system operatively connected to the circuit. The incoming call is communicated to a person remotely located from the receiver. The method comprises disconnecting the audible signal system, and placing on the person a pager having a receiver circuit capable of sensing the existence of an incoming call destined for the incoming call circuit of the telephone receiver. The pager having a silent announcer thereon operatively connected to the receiver circuit of the pager. Thus, the presence of an incoming call can be transmitted to the receiver circuit of the pager to actuate the vibrator without actuating the audible signal system of the telephone receiver. 
     French-St. George, et al. in U.S. Pat. No. 6,463,131 Oct. 8, 2002 relates to a system and method for providing multisensory signaling capabilities enables a user to manage the receipt of incoming communication events, after an initial notification sequence, using multiple media options. Specifically, a remote device notifies a user of incoming communication events and offers real-time coupling of the notifications with communication management options. The message is delivered or otherwise processed according to the option selected. 
     U.S. Pat. No. 6,424,251 which issued to Byrne Jul. 23, 2002 describes systems and methods for alerting users of personal electronic devices. In a first aspect these systems and methods alert a user to the occurrence of an event in one or more of the devices by receiving a wireless transmission from the device(s) and then by providing an acoustic, optical, electrical, or mechanical stimulus to the user. In a second aspect these systems and methods may also provide a quiet mode control mechanism through which personal electronic devices are automatically put into a low volume or silent alert operation mode so as not to disturb persons in the vicinity of the devices. This control mechanism may use a wireless transmitter to transmit a signal to any personal electronic device within a given area. 
     U.S. Pat. No. 6,377,823 issued to Higuchi, et al. Apr. 23, 2002 suggests a cellular mobile telephone apparatus including a main body, and an alarm device which is provided separately from the main body, the main body including: receiving/transmitting unit for receiving and transmitting radio frequency signals between a base station; modulating/demodulating unit for modulating and demodulating between the radio frequency signals, and a conversation signal and a control signal; telephone receiver unit for reproducing audible conversation voice in response to the demodulated conversation signal from the modulating/demodulating unit; telephone transmitting unit for converting conversation voice into the conversation signal; a controller for controlling operation of the main body of the cellular mobile telephone apparatus in accordance with the control signal; and an alarm device for providing an alarm signal which includes an identification information and is transmitted through the radio frequency, when a call is terminated at the main body; and the alarm device including: receiving unit for receiving the alarm signal of radio frequency; a discriminatory for discriminating the alarm signal assigned to itself from others by the identification information included therein; and an alarm unit for alarming call termination in response to the identification by the discriminator. 
     Adler in U.S. Pat. No. 6,424,252 issued Jul. 23, 2002 relates to a paging system for washers and dryers including a transmitter adapted for coupling with a washer and dryer. The transmitter can detect an end of a cycle of the washer and dryer. The transmitter includes a plurality of function buttons. A receiver is provided that is adapted for being worn by the person. The receiver is in communication with the transmitter whereupon the transmitter detecting the end of the cycle, the receiver will be sent a signal. The receiver includes an alarm that is activated upon receiving the signal. The receiver includes a plurality of function buttons. 
     Burnette in U.S. Pat. No. 6,299,345 Oct. 9, 2001 describes providing a chess player with a pager so that the chess player can leave the chess board and still be notified when it is time for the chess player to make his move. A conventional chess timer has a switch to indicate when an opponent has made a move. The device of Burnette is stated to activate a radio frequency transmitter by the switch to send a signal to a pager tuned to receive the signal sent by the transmitter. When the pager receives the radio frequency signal, the receiver generates a vibration and/or turns on a light, and/or less preferably generates a sound whereby a player can be notified at a remote location that an opponent has made his move. 
     U.S. Pat. No. 6,150,927 issued to Nesbitt Nov. 21, 2000 discusses an anti-vandalism detection and alarm system is disclosed for detecting and reporting the scratching of relatively hard materials such as glass and plastic which generate characteristic sound or vibration frequencies during scratching, and for detecting and reporting the cutting and slashing of relatively soft materials such as fabric, leather and plastic. 
     U.S. Pat. No. 6,064,309 dated May 16, 2000 and issued Sellers, et al. describes a swimming pool drowning prevention safety system.

     DETAILED DESCRIPTION OF THE INVENTION 
     As best seen in  FIG. 1 , is an system  10  for communicating with the hearing impaired, visually impaired, or otherwise physically impaired individual such as in a wheel chair. The first aspect of the present invention is a first transceiver  20 . The first transceiver  20  employs a first transceiver microphone  22  for receiving audible signals. 
     The first transceiver  20  further employs a first computer chip or circuit  24 . The first computer chip or circuit  24  is capable of receiving an audible impulse. The audible impulse is convertible by the first computer chip or circuit  24  into an electrical signal which in turn is convertible to radio frequency (RF) signal.

The power source  32  may also employ a battery having direct current to power the first transceiver microphone  22 , the first computer chip or circuit  24 , the first visual display  28 , and the first speaker  30 . Alternatively, the power source  32  for the first transceiver  20  may be a combination of 110 volts alternating current converted by a power converter to 12 volts direct current to power the first transceiver microphone  22 , the first computer chip or circuit  24 , the first visual display  28 , and the first speaker  30 . 
     The second transceiver  40  further employs a second computer chip or circuit  44 . The second computer chip or circuit  44  is capable of receiving an audible impulse. The audible impulse is convertible by the second computer chip or circuit  44  into an electrical signal which in turn is convertible to radio frequency (RF) signal. 
     As best seen in  FIG. 2  the first transceiver  20  has a learning switch  100 . The learning switch  100  has an on mode  102 , an off mode  104 , and a reset mode  106 . In the on mode  102  the learning switch  100  is capable of transmitting an electrical current. In the off mode  104  the learning switch  100  will not transmit an electrical current. In the reset mode  106  the learning switch  100  is set for reprogramming the system for communicating to the hearing or visually impaired. 
     The second transceiver  40  utilizes a second antenna  46  for the output of the radio frequency (RF) signal. The second transceiver  40  and also employs a second visual display  48 . The second transceiver  40  and further comprises a second speaker  50 . 
     The second transceiver  40  is powered by a power source  52 . The power source  52  is conveniently 110 volts alternating current converted by a power converter (not shown) to 12 volts direct current to power the second transceiver microphone  42 , the second computer chip or circuit  44 , the second visual display  48 , and the second speaker  50 . The power source  52  may also employ a battery having direct current to power the second transceiver microphone  42 , the second computer chip or circuit  44 , the second visual display  48 , and the second speaker  50 . Alternatively, the power source  52  for the second transceiver  50  may be a combination of 110 volts alternating current converted by a power converter to 12 volts direct current to power the second transceiver microphone  42 , the second computer chip or circuit  44 , the second visual display  48 , and the second speaker  50 . 
     As best seen in  FIG. 3  the second transceiver  40  has a second learning switch  200 . The second learning switch  200  has an on mode  202 , an off mode  204 , and a reset mode  206 . In the on mode  202  the second learning switch  200  is capable of transmitting an electrical current. In the off mode  204  the second learning switch  200  will not transmit an electrical current. In the reset mode  206  the second learning switch  200  is set for reprogramming the system for communicating to the hearing or visually impaired. 
     The third transceiver  60  further employs a third computer chip or circuit  64 . The third computer chip or circuit  64  is capable of receiving an audible impulse. The audible impulse is convertible by the third computer chip or circuit  64  into an electrical signal which in turn is convertible to a radio frequency (RF) signal. 
     The third transceiver  60  utilizes a third antenna  66  for the output of the radio frequency (RF) signal. The third transceiver  60  also employs a third visual display  68 . The third transceiver  60  further comprises a third speaker  70 . 
     The third transceiver  60  is powered by a power source  72 . The power source  72  is conveniently 110 volts alternating current converted by a power converter (not shown) to 12 volts direct current to power the third transceiver microphone  62 , the third computer chip or circuit  64 , the third visual display  68 , and the third speaker  70 . The power source  72  may also employ a battery having direct current to power the third transceiver microphone  62 , the third computer chip or circuit  64 , the third visual display  68 , and the third speaker  70 . Alternatively, the power source  72  for the third transceiver  60  may be a combination of 110 volts alternating current converted by a power converter to 12 volts direct current to power the third transceiver microphone  62 , the third computer chip or circuit  64 , the third visual display  68 , and the third speaker  70 . 
     As best seen in  FIG. 4  the third transceiver  60  has an on off switch  300 . The on off switch  300  is employed to operate the third microphone  62  of the third transceiver  60 . A haptic mechanism is shown as  302  in  FIG. 4 . The haptic mechanism is conveniently mounted in a pager or is wrist mounted, as in a wrist watch, to alert the hearing or visually impaired person of a communication from the first transceiver  20  or the second transceiver  40 . 
     In operation, the system for communicating with the hearing or visually impaired permits a differently abled person to receive communications which would otherwise be impossible or difficult to obtain. 
     When it is desired to obtain the operation of the system for communicating with the hearing or visually impaired the first transceiver  20  is placed in close proximity to the source of a sound to be generated. For example, the first transceiver  20  may be placed near a first telephone (not shown). The first transceiver  20  is then activated by turning the learning switch  100  to the on mode  102 . 
     With the learning switch  100  in the on mode  102  the first telephone is activated in proximity to the first transceiver microphone  22  of the first transceiver  20 . It is best that the first transceiver  20  and the first telephone are in a normally quiet area to avoid extraneous sounds. 
     The first transceiver  20 , after receiving the desired sound generated by the first telephone, is thus programmed to recognize the sound (ringing) corresponding to the first telephone. The first transceiver  20  then has the learning switch  100  placed in the off mode  104 . In the off mode  104  the first transceiver  20  is capable as later discussed of transmitting the sound learned in this operation. If the first transceiver  20  does not adequately function then the first transceiver  20  may have the reset mode  106  activated to remove the prior learned sound. The first transceiver  20  may then be reprogrammed for the desired sound as discussed above. 
     The second transceiver  40  is programmed has described above to learn a second sound such as a second telephone. The device which generates the sound may be a doorbell, a washer or dryer, a burglar alarm, a child crying, or the like. In practice, there is no limit to the number of transceivers employed in the present invention. For illustrative purposes only, this application discusses the use of a first transceiver  20  and a second transceiver  40 . 
     The sound received by the first transceiver  20  is converted by the first computer chip or circuit  24  into a radio frequency signal. The radio frequency signal is broadcast by the first antenna  26 . The strength of the radio signal should be sufficient to reach a receiver no more than 100 meters distant. 
     The third transceiver  60  receives the radio frequency signal generated by the first transceiver  20  through the third antenna  66 . A third computer chip or circuit  64  converts the radio frequency signal received by the third receiver  60  as a haptic signal (vibration) which is felt by an individual in close proximity to the third receiver  60 . 
     The third transceiver  60  may generate a variety of haptic signals to permit the individual in close proximity to the third receiver  60  to determine which of the first transceiver  20  or the second transceiver  40  is transmitting the signal indicating that a specific sound corresponding to, for example a telephone ringing, and some action by the individual may be required. The haptic signal may be coded such as by the frequency or number of vibrations. 
     The third transceiver  60  may also visually display on the third visual display  68  a message indicating the source of the transmission from the first transceiver  20 . The mode where a visual message is displayed on the third visual display  68  displayed this is aware the individual is hearing impaired in the situation where the haptic signal is the sole signal given this mode is particularly useful for the visually impaired. 
     The third transceiver  60  may communicate with the first transceiver  20  to the third transceiver microphone  60 , such as when utilized by a visually-impaired person or by a hearing-impaired person with sufficient speaking ability to alert a third party in proximity to the first transceiver  20  that the third transceiver  60  has received a communication from the first transceiver  20 . The first transceiver  20  may provide this communication audibly through the first speaker  30 . It is also possible to utilize the on off switch  300  to deliver a prerecorded message to the first transceiver  20 . In the foregoing manner, a hearing person may receive a message that a hearing-impaired person desires to receive a communication from the hearing person. Similarly, a visually impaired person may require additional time to; for example, answer the door of a home. The visually impaired person thus may from a distance alert the person who initiated contact with the first transceiver that the communication has been received at the third transceiver by the visually impaired person.
