Abstract

An apparatus for providing a temperature based alerting signal to a user to alert the user to the occurrence of a particular or predetermined event. The temperature based alerting device may be incorporated into jewelry, garments, or a releasable strap and includes at least one spot heating element that is maintained in substantial contact with the user'"'"'s skin. Upon detected occurrence of the predetermined event, as for example an incoming telephone call or page, the user is silently alerted by a change in the temperature of the spot heating element in contact with the user'"'"'s skin. Subsequent action by the user, as for example answering of the incoming call or page, causes the temperature based alerting device to reset to an initial, non-alert state.

Claims

1. A method for generating a temperature based alerting signal for alerting a user to an occurrence of a predetermined event, comprising the steps of:

providing a temperature based alerting device having a heating element disposed in substantial contact with the user'"'"'s skin;

initializing, prior to occurrence of the predetermined event, the temperature based alerting device to a predetermined initial temperature;

setting a temperature change limit for the temperature sensitive alerting device;

changing the temperature of said heating element from the initial temperature to a second temperature greater than the initial temperature upon detection by the alerting device of the occurrence of the predetermined event to alert the user to the occurrence of the predetermined event; and

resetting the temperature of said heating element from the second temperature to the initial temperature when the user has responded to the alert of the occurrence of the predetermined event.

2. The method set forth in claim 1, wherein said predetermined event comprises receipt by the alerting device of an incoming communication signal from a remotely-disposed outside source, and wherein the user response comprises answering the incoming communication signal.

3. The method set forth in claim 2, wherein the incoming communication signal is designated for one of a wireless telephone and a paging device.

4. The method set forth in claim 3, further comprising the step of generating a wireless control communication signal for transmission by the one of the telephone and the paging device to the alerting device for activating the heating element to change its temperature from the initial temperature to the second temperature.

5. The method set forth in claim 2, further comprising the step of applying the incoming communication signal directly to the alerting device to cause it to change the temperature of the heating element from the initial temperature to the second temperature.

6. The method set forth in claim 1, further comprising the steps of:

providing a transmitting device remote from the alerting device for transmitting wireless communication signals on a predetermined repetitive basis; and

monitoring at the alerting device receipt of the transmitted wireless communication signals;

said predetermined event comprising determining at the alerting device an absence of receipt of the transmitted wireless communication signals for a predetermined period of time, and wherein said user response comprises relocating the alerting device relative to the transmitting device so that the alerting device is within a transmitting range of the transmitting device for receipt of the communication signals by the alerting device.

7. The method set forth in claim 1, wherein said step of providing comprises incorporating the alerting device with the heating element integrally into a piece of jewelry wearable by the user.

8. The method set forth in claim 1, wherein said step of providing comprises incorporating the alerting device with the heating element integrally into an article of clothing wearable by the user.

9. The method set forth in claim 6, wherein said transmitter is provided for releasable attachment to one of an object, a person, and an animal for enabling the user to monitor a predetermined proximity of the object, person and animal to the user.

10. An apparatus for generating temperature based alerting signals to a user in response to an incoming communication signal designated for a wireless communication device, comprising:

a temperature based alerting device having a power source, a switch element coupled to said power source and a heating element coupled to said switch element, and disposable in contact with the user'"'"'s skin; and

means for applying a control signal to said alerting device in response to receipt by said means of the incoming communication signal to cause said switch element to close and apply an actuating signal to said heating element, said heating element being configured to heat up in response to of the applied actuation signal and thereby alert the user to the presence of incoming communication signal.

11. An apparatus in accordance with claim 10, wherein said alerting device further comprises an antenna for receiving said control signal.

12. An apparatus in accordance with claim 11, wherein said means for applying comprises an inserting device connected with the wireless communication device and operable for generating said control signal in response to said receipt of the incoming communication signal and for disabling an audible alert signal normally produced by the wireless communication device.

13. An apparatus in accordance with claim 12, wherein said alerting device further comprises a microprocessor for controlling operation of the alerting device.

14. An apparatus in accordance with claim 13, wherein the incoming communication signal is received directly by said antenna and defines said control signal, and wherein said microprocessor is operable for controlling said switch to close in response to the receipt of the incoming communication signal.

15. An apparatus in accordance with claim 13, wherein said switch element comprises an operational amplifier having a signal input for receiving said control signal, a reference input, and an output for outputting said control actuation signal to said alerting device.

16. An apparatus in accordance with claim 15, wherein said microprocessor is operable to provide a reference signal representing a reference temperature for application to said reference input.

17. An apparatus in accordance with claim 16, wherein said microprocessor is operable to monitor an ambient temperature of said alerting device and to apply the reference signal representing the monitored ambient temperature to said reference input.

18. An apparatus for generating temperature based alerting signals to alert a user to an occurrence of a predetermined event, comprising:

a temperature based alerting device having a power source, a switch element coupled to said power source and a heating element coupled to said switch element and maintainable in substantial contact with the user'"'"'s skin;

transmitting means remote from said alerting device for transmitting communication signals to said alerting device on a repetitive basis; and

means for controlling said switch element to close and thereby activate the heating element in response to a lack of receipt by the alerting device of the transmitted communication signals for a predetermined period of time.

19. An apparatus in accordance with claim 18, wherein said closing of the switch element applies a current signal to said heating element to cause, said heating element to heat up as a result of the applied current signal and thereby alert the user to the lack of receipt of the transmitted communication signals.
