摘要： A free space optical bus system and method are provided for connecting two units of circuitry across a free space gap. A first unit of circuitry includes a multiplexer that combines a plurality of bus signals to obtain an electronic combined signal and a laser that is driven by the electronic combined signal to transmit an optical signal. A second unit of circuitry is separated from the first unit of circuitry by a free space gap. The second unit of circuitry includes a photodetector that receives the optical signal and transforms it into an electronic composite signal and a demultiplexer that divides the composite signal into a plurality of constituent signals.

摘要： A transistor according to the invention for simultaneously providing at least two current-voltage characteristics includes a base, a collector, and an emitter. At least one of the base, collector, and emitter includes a first layer grown using molecular beam epitaxy (MBE). The first layer includes a first strip having a first doping characteristic created using focused ion beam processing. A second strip has a second doping characteristic created by focused ion beam processing. A middle section of undoped material is located between the first and second strips. A resonant tunneling junction is grown on the first layer using MBE and includes a plurality of layers.

摘要： A method of making a micro-miniature switch device (10), which has at least one member (68) movable relative to a substrate (12) upon which the device is provided, includes providing a layer of sacrificial non-photolithography material upon a stratum connected to the substrate. A template is provided via photolithographing step that uses a photoresist material upon a stratum connected to the substrate. A layer is provided to include at least a portion of the movable member. The photoresist material and the sacrificial non-photolithography material are removed using photoresist developer. Preferably, at least two photolithography process steps utilize a single photolithographic mask. Also preferably, substrate material is removed to create a recess and at least one channel into the substrate, wherein the channel intersects the recess. At least a portion of the movable member is provided at a location within the recess and at least a portion of the movable member is provided at a location within the channel.

摘要： A micro-miniature switch apparatus (10) includes a substrate (12) having a surface (14) with first and second channels (16, 18) extending from the surface (14) into the substrate (12). The first and second channels (16, 18) are spaced apart from each other, with a channel axis (20) extending longitudinally through the first and second channels (16, 18). A body (68) that is movable relative to the substrate (12) includes two arms (70, 72). Each of the arms (70, 72) extends into one of the first and second channels (16, 18) to support the body (68) for movement relative to the substrate (12) between first and second electrical conditions of the switch apparatus (10).
