Abstract

An automatic telephone number dialing circuit powered from a standard telephone network wire for storing telephone numbers using non-volatile memory including a one-touch dialing device that enables a user to automatically dial a plurality of telephone numbers that are pre-programmed in non-volatile read only memory of an integrated circuit.

Claims

1. A non-volatile memory circuit for automatically dialing a telephone number comprising:

a) at least one connection to a telephone network wire, said telephone network wire having an electrical input and an electrical output,

b) a telephone dialer circuit, said telephone dialer circuit having the capability to dial a telephone number using a tone or a pulse dialing mode,

c) a micro controller circuit having a non-volatile memory storage, said non-volatile memory storage being capable of storing at least one telephone number,

d) a plurality of jumper switches having an on and an off state,

i) said plurality of jumper switches being capable of;

a) selecting the tone dialing mode in the telephone dialer circuit when a first jumper is in the on state, and,

b) selecting the pulse dialing mode in the telephone dialer circuit when the first jumper is in the off state, and,

c) choosing one of at least one telephone number stored in said non-volatile memory when a second jumper is in the on state,

e) a latch circuit having an on and an off state,

f) an electrical switch capable of being in an on or an off state,

i) when said electrical switch is placed in the on state, the electrical switch receives a current from said first telephone network wire to flow throughout the non-volatile memory circuit for automatically dialing a telephone number, thereby initiating the latch circuit to change to the on state and remain in the on state until the telephone dialer circuit completes a dialing sequence,

ii) said dialing sequence comprises;

a) the micro controller providing one of the plurality of stored telephone numbers in said non-volatile memory to the dialing circuit,

b) the dialing circuit dialing one of the plurality of stored telephone numbers,

iii) when said dialing sequence has completed, said latch circuit returns to the off state,

iv) when said latch circuit is in the off state, no current will flow in the non-volatile circuit, said latch circuit is electrically coupled to said micro controller circuit,

said latch circuit is electrically coupled to said electrical switch, said telephone dialer circuit is electrically coupled to said micro controller circuit, said plurality of jumper switches are electrically coupled to the micro controller circuit.

2. The non-volatile circuit of claim 1 wherein a second telephone connection having an electrical input and an electrical output, is electrically coupled to a telephone handset,

a) said second telephone connection is electrically coupled to the at least one connection to a telephone network wire,

b) said input of said second telephone wire being capable of receiving a second standard telephone wire that is electrically coupled to a second telephone network wire that is capable of conducting electrical current to provide power to the telephone handset,

c) said output of said second telephone wire being capable of conducting pulse or tone dialing signals.

3. The non-volatile circuit in claim 1, wherein said micro controller is a Microchip PIC16C5X integrated circuit, having a programmable read only memory capable of storing a plurality of telephone numbers.

4. The non volatile circuit in claim 1, wherein said dialer circuit is a National Semiconductor TP5008 integrated circuit.

5. The non volatile circuit in claim 1, wherein said electrical switch is capable of being momentarily placed in the on state by a resilient button, said resilient button being mechanically coupled to said electrical switch.

6. The electrical switch in claim 5, wherein when said resilient button is depressed, the dialer circuit receives the telephone numbers stored in said non-volatile memory in said micro controller in electronic form and the micro controller initiates said dialer circuit to begin a dialing sequence to dial said stored number.

7. The non volatile circuit in claim 1, wherein the input and output of the connection of the non-volatile memory circuit to the telephone network wire is protected via a surge protecting circuit.

8. A method of manufacturing a device for automatically dialing a telephone number using a non-volatile memory circuit by:

a) providing at least one connection to a telephone network wire, said telephone network wire having an input and an output,

b) providing a telephone dialer circuit, said telephone dialer circuit having the capability to dial a telephone number using a tone or a pulse dialing mode,

c) providing a micro controller circuit having a non-volatile memory storage, said non-volatile memory storage being capable of storing at least one telephone number,

d) providing a plurality of jumper switches having an on and an off state,

i) said plurality of jumper switches being capable of;

a) selecting the tone dialing mode in the telephone dialer circuit when a first jumper is in the on state, and,

b) selecting the pulse dialing mode in the telephone dialer circuit when the first jumper is in the off state, and,
