[0001]     This application claims the benefit of Provisional Application U.S. Ser. No. 60/681,614, filed May 17, 2005. 
     
    
     BACKGROUND OF THE INVENTION  
       [0002]     A common occurrence in many homes is the situation where a teenage person of the family is located on a second-floor or on a basement floor of a multi-floor dwelling listening to loud music either through loudspeakers or through headphones. If this teenage person of the family needs to be summoned for dinner or to answer the telephone, since the teenage person cannot be reached through an audible shout from the teenage person&#39;s parent, the parent must either climb the stairs to knock loudly on the teenage person&#39;s door or descend the stairs to confront the teenage on the level below. In either case the physical exertion of ascending or descending the stairs to summon the teenage person is an aggravation to the parent.  
         [0003]     The present inventor has recognized that it would be beneficial to provide a system for contacting the otherwise audibly inaccessible teenage person and alleviating the burden of the parent ascending or descending stairs to reach and contact the teenage person.  
       SUMMARY OF THE INVENTION  
       [0004]     The invention provides a wireless system for alerting a teenager or other hearing deprived person within a dwelling who cannot be reached by an audible call or shout. The invention provides a wireless system for alerting a teenager who cannot be reached by an audible call or shout that is inexpensively manufactured, easily installed in the dwelling, and effective for its purpose.  
         [0005]     Although the present invention is particularly advantageous to summon a teenager listening to loud music, it is also effective to summon any other hearing deprived person, whether that person is listening to loud music or is hearing-impaired.  
         [0006]     The preferred embodiment of the present invention includes a sending unit that would typically be located on the ground floor of a dwelling, such as in the kitchen. The sending unit would include a call button, a sending unit power supply, and a transmitter. The transmitter would include an antenna to wireless transmit a call signal for a relatively short distance, such as from between the kitchen and an upstairs bedroom. A receiving unit would be mounted in the receiving location such as in the upstairs bedroom. The receiving unit would include a receiving antenna that is operatively connected to a control. The control is powered by a receiving unit power supply. The control controls a annunciator lamp. The annunciator lamp can be an LED type lamp that is easily sensed when turned on. The controller can also control an audible annunciator such as a buzzer, siren, or speaker that emits an audible signal, supplementary to the annunciator lamp.  
         [0007]     The sending unit and receiving unit can be provided with hook and loop (VELCRO) attachments for temporarily attaching the sending unit to a downstairs wall and the receiving unit to a wall in the upstairs bedroom.  
         [0008]     As an enhancement to the invention, the sending unit can include multiple call buttons, each call button coded by its purpose. For example, a first call button could be for announcing to the teenager that he or she is wanted on the telephone, the second call button could be for announcing to the teenager that he or she is instructed to come downstairs for dinner, etc. A corresponding annunciator lamp for each purpose could be provided on the receiving unit. The sending unit would issue a corresponding wireless call signal for each call button and the sending unit would illuminate the corresponding annunciator lamp.  
         [0009]     As another enhancement of the invention two or more call buttons can be configured with the transmitter unit of the sending unit to issue different wireless signals to different receiving units to cause the respective annunciators of those units to operate. Thus, a single sending unit can be selectively used to summon persons in different rooms of the dwelling. This is particularly advantageous when more than one teenager lives in the dwelling.  
         [0010]     The invention is particularly advantageous in that it is compact, inexpensively manufactured, easily removed when no longer desired and effectively utilized.  
         [0011]     Numerous other advantages and features of the present invention will be become readily apparent from the following detailed description of the invention and the embodiments thereof, from the claims and from the accompanying drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0015]     While this invention is susceptible of embodiment in many different forms, there are shown in the drawings, and will be described herein in detail, specific embodiments thereof with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the specific embodiments illustrated.  
         [0016]      FIG. 1  illustrates in schematic form a typical household. The system  10  according to the invention is mounted within a dwelling  12 . In the dwelling  12 , a parent  14  is located on a ground floor. A teenager  16  is located some distance away in a bedroom  17  on an elevated second-floor. The teenager  16  is wearing headphones  18  which are supplied with loud music from a stereo or other type music player  19 . It was heretofore known that if the teenager  16  received a telephone call, was needed to come downstairs for dinner, or received a visitor at the door, that the parent  14 , despite repeated shouts, would be required to climb the stairs to the second-floor and bang loudly on the door to summon the teenager, who could then to receive instructions once the headphones were removed.  
         [0017]     According to the system of the invention, a sending unit  22  is conveniently mounted on the ground floor of the dwelling, such as in a front hallway, or in the kitchen, or other easily accessible place. A receiving unit  26  is mounted within the teenager&#39;s bedroom  17 , preferably on the wall in a visually attention-getting location.  
         [0018]      FIG. 2  illustrates in schematic form the system  10 . The sending unit  22  is mounted onto a wall  30  by a strip of hook and loop (VELCRO) tape  32  that is adhesively secured to the wall and a strip of mating hook and loop (VELCRO) tape  34  that is adhesively secured to a body  35  of the sending unit  22 . The receiving unit  26  is mounted in similar fashion to an upstairs wall  40  using similar hook and loop (VELCRO) strips  42 ,  44 . The hook and loop (VELCRO) strip  42  is adhesively secured to the wall  40 . The mating hook and loop (VELCRO) strip  44  is adhesively secured to the receiving unit  26 .  
         [0019]     The sending unit  22  includes a sending unit power supply, such as provided by a battery  52 , one or more call buttons  54 ,  55  and an electronic transmitter  56  connected to a transmitting antenna  58 . The transmitter  56  preferably issues a RF signal.  
         [0020]     The receiving unit includes a wireless signal receiver  65 , optionally one or more audible annunciators  68  (one shown), one or more annunciator lamps  70 ,  71 , and a power supply such as a battery  72 . The receiver  65  can include a control unit  66  that is connected to a receiving antenna  62 .  
         [0021]     In operation, when the parent needs to summon the otherwise audibly-inaccessible teenager  18 , a call button  54  or  55  is pushed by the parent, which causes thy transmitter  56  to issue a wireless signal from the antenna  58 . The receiving antenna  62  receives the signal and the control unit  66 , having a switching function therein, causes one or more annunciator lamps  70 ,  71  to illuminate, either in a flashing manner or a steady manner to alert the teenager. Preferably, the annunciator lamps  70 ,  71  are LED lights which radiator bright light and are more likely to get the teenager&#39;s attention.  
         [0022]     The call buttons  54 ,  55  can be labeled for the category of communication from the parent, such as “answer the phone” or “come to dinner”, etc. Although two call buttons and two lamps are shown, it is encompassed by the invention that only one general call button and one annunciator lamp be used, or that more than two call buttons and lamps be used.  
         [0023]     The receiving unit  26  can also include one or more audible annunciators  68  which could be buzzers, sirens, speakers, etc. that issue an audible signal to alert the teenager. It is possible that the audible annunciators  68  could issue a different audible tone depending on the nature of the parental message.  
         [0024]     It is also possible that the one or more lamps  70 ,  71  could differentiate the category of message from the parent by a flashing code, different color lights or other difference in appearance.  
         [0025]     A further enhancement of the invention could be that the call buttons  54 ,  50  could be allocated to annunciator lamps  71 ,  72 , and optionally audible annunciators (not shown) located on two different receiving units  26   a ,  26   b  as illustrated in  FIG. 3 . The transmitter  56  within the sending unit  22  could be configured to transmit a different signal upon activation of the respective buttons  54 ,  55 , wherein the corresponding signal would be received by the corresponding receiving unit  26   a ,  26   b . Two or more call buttons corresponding to two or more receiving units could be employed. Thus, the invention is particularly advantageous for families having two or more teenagers, wherein the selected teenager could be summoned by a parent pushing the corresponding call button.  
         [0026]     The wireless signal issued by the sending unit and received by the receiver unit could be selected from a number of known systems, such as those used for wireless computer networks (LAN) or the systems used for garage door openers. Preferably, the signal is a selected RF signal frequency, such as used in garage door openers. Other wireless signals, of any frequency including infrared, microwave, ultrasonic, sound waves, are also encompassed by the invention.  
         [0027]     A description of transmitters and receivers for garage door openers, which description can be modified for use in the practice of the present invention, can be found in U.S. Pat. No. 5,990,828, herein incorporated by reference. The security features, such as special codes, rolling codes and encryption, and those features particular to operation of the garage door, would probably not be needed to practice the present invention.  
         [0028]     According to the invention the sending unit  22  and the receiving unit  26  are small, lightweight units having plastic surrounding casings. Although the units are shown as battery powered, other power supplies, such as wiring from the dwelling electric supply are also encompassed by the invention.  
         [0029]     From the foregoing, it will be observed that numerous variations and modifications may be effected without departing from the spirit and scope of the invention. It is to be understood that no limitation with respect to the specific apparatus illustrated herein is intended or should be inferred
