Abstract:
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.
