Abstract

A signal transmitting and receiving bracelet system for notifying a user wearing a receiving bracelet that a user wearing a transmitting bracelet is in danger. The signal transmitting and receiving bracelet system includes a transmitting bracelet that has sensing and transmitting circuitry having a pressure transducer adapted for contacting a pulse point of a wrist of a user for sensing a pulse of a user. The sensing and transmitting circuitry also has a transmitter that is electrically connected to the pressure transducer to emit a first signal when a user'"'"'s pulse rate is higher than a predetermined rate. A receiving bracelet has receiving circuitry with a receiver adapted for receiving signals emitted from the transmitting bracelet. The receiving circuitry has a sound emitting device that is electrically connected to the receiver for emitting a sound when a signal is received from the transmitting bracelet.

Claims

1. A bracelet system for notifying a user wearing a receiving bracelet that a user wearing a transmitting bracelet is in danger, comprising, in combination:

a transmitting bracelet, comprising;

a strap adapted for wrapping around a wrist of a user;

said strap having sensing and transmitting circuitry having a pressure transducer adapted for contacting a pulse point of a wrist of a user for sensing a pulse of a user, said pressure transducer emitting electrical signals corresponding to the pulse rate of the wearer; and

said sensing and transmitting circuitry having a transmitter being electrically connected to said pressure transducer for emitting a first signal when a user'"'"'s pulse rate is higher than a predetermined rate; and

a receiving bracelet, comprising;

a strap adapted for wrapping around a wrist of a second user;

said strap having receiving circuitry having a receiver adapted for receiving signals emitted from said transmitting bracelet; and

said receiving circuitry having a sound emitting device being electrically connected to said receiver for emitting a sound when a signal is received from said transmitting bracelet.

2. The bracelet system of claim 1, wherein said transmitter of said transmitting bracelet emits a second signal when a user'"'"'s pulse rate is lower than a predetermined rate.

3. The bracelet system of claim 2, wherein said sound emitting device of said receiving bracelet emits a distinct second sound when said second signal is received from said transmitting bracelet.

4. The bracelet system of claim 1, wherein said transmitter of said transmitting bracelet includes an antenna.

5. The bracelet system of claim 1, wherein said sensing and transmitting circuitry of said transmitting bracelet has a controller for taking an average of voltage levels coming from said pressure transducer and corresponding to a pulse rate, said controller sending a primary signal to said transmitter when the voltage levels are higher than a predetermined level for a predetermined amount of time, said controller sending a secondary signal to said transmitter when the voltage levels are lower than a predetermined level for a predetermined amount of time.

6. The bracelet system of claim 5, wherein said controller ignores a predetermined number of maximum and minimum values for a predetermined amount of time.

7. The bracelet system of claim 5, wherein said sensing and transmitting circuitry has a memory module being in communication with said controller, said memory module containing instructions.

8. The bracelet system of claim 7, wherein said memory module is removable.

9. The bracelet system of claim 1, wherein said sound emitting device of said receiving bracelet emits a distinct first sound when said first signal is received from said transmitting bracelet.

10. The bracelet system of claim 1, wherein said receiver of said receiving bracelet includes an antenna.

11. The bracelet system of claim 1, wherein said receiving circuitry of said receiving bracelet has a controller for monitoring said receiver for signals, said controller activating said speaker when said receiver receives a signal from said transmitting bracelet.

12. A bracelet system for notifying a user wearing a receiving bracelet that a user wearing a transmitting bracelet is in danger, comprising, in combination:

a transmitting bracelet, comprising;

a strap adapted for wrapping around a wrist of a user and having spaced apart first, second, and third portions and a pair of elastic bands coupling said portions together;

said first portion of said strap having one portion of a hooks and loops fastener coupled thereto towards a free end thereof;

said first portion of said strap having a complementary portion of a hooks and loops fastener coupled thereto and positioned between said one portion and said second portion of said strap such that folding of the free end of the first portion back on itself permits coupling of said portions of said hooks and loops fastener together;
