Abstract:
1. A method for remotely determining a status of a door lock, said method comprising: a receiver device receiving a broadcast signal from a broadcast device built into a door, said door lock configured to lock and unlock the door, said receiver device located remotely from the door, said broadcast signal comprising a door lock status of the door lock, said door lock status comprising a first input bit of 0 or 1 and a second input bit of 0 or 1; a main receiver circuit within the receiver device using a first AND gate and a second AND gate within the main receiver circuit to process the first input bit and the second input bit to generate a first output bit and a second output bit, respectively; and said main receiver circuit storing the first and second output bits in a memory location within the receiver device, wherein the receiver device comprises a display circuit comprising a third AND gate, a fourth AND gate, a first pass transistor, a second pass transistor, a first light and a second light, wherein the third AND gate comprises a first input having a fixed value of 1, a second input, and an output coupled to an input of the first pass transistor, wherein the fourth AND gate comprises a first input having the fixed value of 1, a second input, and an output coupled to an input of the second pass transistor, wherein an output of the first pass transistor is coupled to an input of the first light, wherein an output of the second pass transistor is coupled to an input of the second light, wherein the receiver device is a key fob device comprising a display button which if pressed causes the door lock status in the memory location to be displayed, and wherein the method further comprises:
