Abstract

An object-oriented programmable dedicated dialer device includes a hollow disc-shaped body having a front cover and a rear base facing and attached with one another and defining an interior cavity, a telephone number dialing mechanism disposed in the interior cavity and mounted on the rear base, and a touch sensor mounted to the hollow body and connected to the telephone number dialing mechanism. The telephone number dialing mechanism includes a microcontroller, a battery, and a sound-generating transducer. The microcontroller stores a telephone number in its memory. The touch sensor is operable in response to a user touching the touch sensor to convert the microcontroller from a deactivated to activated to cause the dialing mechanism to dial the stored telephone number. Thus, when the touch sensor is touched activating the microcontroller, the dialing mechanism begins operation to generate the plurality of DTMF tones necessary to dial the stored telephone number. The touch sensor and a graphic or logo of the organization whose telephone number is stored in the microcontroller are mounted on the exterior of the front cover of the hollow body.

Claims

1. A dedicated dialer device, comprising:

(a) a hollow body defining an interior cavity therein;

(b) control means disposed in said interior cavity for storing a predetermined telephone number and for producing a plurality of tones necessary to dial the stored predetermined telephone number, said control means being an automatic telephone number dialing mechanism disposed in said interior cavity, said dialing mechanism including a microcontroller, a power supply and a sound-generating transducer being electrically connected together, said microcontroller storing the predetermined telephone number; and

(c) a touch sensor connected to said control means and being operable in response to a user touching said touch sensor for converting said control means in a non-switching manner from a deactivated state to an activated state to cause said control means to dial the stored predetermined telephone number, said touch sensor including an electrically-conductive touch plate mounted to the exterior of said hollow body, drive circuitry disposed in said internal cavity and electrically coupled to said microcontroller and conductor means extending from said touch plate to said drive circuitry and electrically connecting said touch plate to said drive circuitry, said drive circuitry being set at an electrical potential sufficiently different from that of a human user such that said drive circuitry is adapted to receive an injection of electrical current sufficient to cause actuation of said microcontroller in response to a human user physically touching said touch plate.

2. The device of claim 1 wherein said hollow body has a front cover and a rear base facing one another and being attached with one another and together defining said interior cavity in said hollow body.

3. The device of claim 2 wherein each of said front cover and rear base has a flat main panel and an annular rim surrounding and attached to a periphery of said main panel.

4. The device of claim 3 wherein said front cover has an object-oriented graphic imprinted on said flat main panel thereof.

5. The device of claim 3 wherein said front cover and rear base having interfitting elements defined on said annular rims thereof for attaching said front cover and rear base together.

6. The device of claim 3 wherein said annular rim extends outwardly from one side of said main panel.

7. The device of claim 2 wherein said control means is an automatic telephone number dialing mechanism disposed in said interior cavity and between said front cover and rear base of said hollow body.

8. The device of claim 1 wherein said hollow disc-shaped body is circular in configuration.

9. The device of claim 10 wherein said sound-generating transducer is centered one of a pair of opposite sides of said hollow body.

10. The device of claim 2 wherein said rear base has a magnet mounted on an exterior side thereof.

11. The device of claim 10 wherein said rear base further has a plurality of holes surrounding said magnet which permit passage of the tones generated by said sound-generating transducer from said interior cavity of said hollow body.

12. The device of claim 2 wherein said front cover has an object-oriented graphic imprinted on an exterior side thereof.

13. The device of claim 2 wherein said rear base has a plurality of holes defined therethrough which permits passage of the tones generated by said sound-generating transducer from said interior cavity of said hollow body.

14. A method of programming a telephone number into a dedicated dialer device and of calibrating tone signal frequencies of the programmed telephone number, said method comprising the steps of:

(a) programming a plurality of digits in an automatic telephone number dialing mechanism;

(b) programming a speed calibration byte in the automatic telephone number dialing mechanism;

(c) generating a plurality of dual tone multi-frequency (DTMF) tones;

(d) reading the DTMF tones to determine whether their frequencies are too high or too low relative to a reference level or are the same as the reference level;

(e) changing the value of the speed calibration byte in response to the frequencies of the DTMF tones being too high or too low; and

(f) repeating the method starting at step (a) until the frequency sequence of the DTMF tones are verified as being the same as the reference level.

15. The method of claims 14 wherein said changing of the value of the speed calibration byte includes decreasing the value of the speed calibration byte in response to the frequencies of the DTMF tones being too high.

16. The method of claim 15 wherein said changing of the value of the speed calibration byte includes increasing the value of the speed calibration byte in response to the frequencies of the DTMF tones being too low.

17. The method of claim 14 wherein said changing of the value of the speed calibration byte includes increasing the value of the speed calibration byte in response to the frequencies of the DTMF tones being too low.

18. The method of claim 14 wherein said programming includes digitally downloading the plurality of digits and the speed calibration byte in the automatic telephone number dialing mechanism.
