A distributed wireless sensor network includes two or more wireless nodes adapted for sensing a condition at any first node, first programming located within each node for transmitting a signal representing the sensed condition from the first node to another node, second programming located within each node for receiving the signal transmitted from any other node and for retransmitting a received signal representing the sensed condition along with additional data indicating the number of retransmissions of the signal between nodes.

An embodiment includes an oscillator comprising an amplifier formed on a substrate; a multiple gate resonant channel array, formed on the substrate, including: (a) transistors including fins, each of the fins having a channel between source and drain nodes, coupled to common source and drain contacts; and (b) common first and second tri-gates coupled to each of the fins and located between the source and drain contacts; wherein the fins mechanically resonate at a first frequency when one of the first and second tri-gates is periodically activated to produce periodic downward forces on the fins. Other embodiments include a non planar transistor with a channel between the source and drain nodes and a tri-gate on the fin; wherein the fin mechanically resonates when the first tri-gate is periodically activated to produce periodic downward forces on the fin. Other embodiments are described herein.

Multigate resonant channel transistor

A thermally stabilized, high speed, micrometer-scale silicon electro-optic modulator is provided. Methods for maintaining desired temperatures in electro-optic modulators are also provided. The methods can be used to maintain high quality modulation in the presence of thermal variations from the surroundings. Direct current injection into the thermally stabilized electro-optic modulator is used to maintain the modulation performance of the modulator. The direct injected current changes the local temperature of the thermally stabilized electro-optic modulator to maintain its operation over a wide temperature range.
