Abstract:
A circuit for providing a wakeup function to a quiescent system of networked accessories, said circuit comprising:a ground reference; a voltage source; a logic control device having a plurality of terminals, said logic control device being adapted to selectively communicate current from one or more of said terminals to one or more of said terminals; a user-controllable actuator having a user-controllable actuator first status and a user-controllable actuator second status, said user-controllable actuator causing a closed-circuit to be formed between said ground reference and said voltage source when said user-controllable actuator is in said user-controllable actuator second status; a first electrically controlled switch being disposed in series with the user controllable actuator between the ground reference and the voltage source, said first electrically controlled switch causing a closed circuit to be formed between said voltage source and said logic control device when said user-controllable actuator is disposed in said user-controllable actuator second position; a second electrically controlled switch being disposed in series with the ground reference and the logic control device, said second electrically controlled switch causing a closed circuit to be formed between said voltage source and said logic control device when said logic control device allows current to pass through said second electrically controlled switch; a third electrically controlled switch being disposed in series between said logic control device and said ground reference, said third electrically controlled switch causing a closed circuit to be formed between said voltage source and a system power line when said logic control device allows current to pass through said third electrically controlled switch.
