Patent ID: 8234227

Claim:
An apparatus comprising at least one sensor element, at least one internal element, and a useful output; each said at least one sensor element comprising a first timestamp, a first output coupled to said first timestamp, a first input coupled to the real world, and a sensor threshold, said first timestamp updating responsively to said first input relative to said sensor threshold; said at least one internal element comprising, a second timestamp, a second output coupled to said second timestamp, and a plurality of timestamp inputs, said second timestamp updating responsive to said plurality of timestamp inputs; further coupling each said plurality of timestamp inputs to one of either said first output of said at least one sensor element or to said second output of another said at least one internal element; and generating said useful output signal responsive to at least one said first output or said second output; whereby real world signals enter said apparatus, sensor elements couple to internal elements, and internal elements couple to sensor elements or to other internal elements.
