    摘要： A wavelength-portion controllable optoelectronic switch ("Opsistor") capable of rapid switch frequencies fabricated as a monolithic integrated circuit is disclosed. The Opsistor is comprised of two inverse parallel photodiodes in close proximity, preferably on a monolithic silicon substrate, such that the anode of one photodiode is electrically connected via a first conductor to the cathode of the second photodiode, and the cathode of the first photodiode is electrically connected via a second conductor to the anode of the second photodiode. The voltage-phase of the Opsistor is determined by the relative illumination to the Opsistor's two photodiodes and is rapidly switchable. As a receiving device for data signals, the Opsistor receives programming signals from a transmitter light source. By using different wavelength-portion bandwidth pass filters on each of the two Opsistor photodiodes, a OPS-F device is created, and by using a two-wavelength transmitter light source designated as TM2, a TM2/OPS-F system is created capable of high data transmission rates, and high resistance to signal noise. Applications suitable for the Opsistor and TM2/OPS-F system include high speed optocouplers, linear optical position sensors, edge and target detection sensors, image recognition sensors, the basic subunits of optically based state computers, and high resolution optical encoders.

    摘要： A reading apparatus having a photo-detecting element array constituted by a plurality of photo-detecting element blocks each constituted by a plurality of photo-detecting elements, and having switching elements for transferring charges generated in the photo-detecting elements block by block to an output circuit, in which the output circuit has wirings having no crossing portions and the outputs of the photo-detecting elements can be produced as time-series signals without requiring any external memory. In the reading apparatus, the switching elements are selected block by block of the photo-detecting element array, the blocks are commonly connected so that the respective orders of adjacent two of the blocks in the output circuit are opposite to each other, and an output of the output circuit is selected by two selection circuits synchronized with the selection of the switching elements, the two selection circuits respectively having selection orders which are opposite to each other, whereby the selection circuits are switched block by block of the photo-detecting element array to thereby obtain a time-series output.

    摘要： An erasable optical memory array having at each storage location a non-crystalline, semiconductor threshold switching device. The threshold voltage of each switching device is strongly temperature dependent and each switching device has a finite recovery time when switched to its low resistance state. Means are provided for periodically sampling each of the switching devices with voltage pulses repetitive at a first frequency and having a first voltage level sufficient to switch to the low resistance state only those switching devices heated above room temperature by a thermal image. Additional means are provided to sample the switching devices at a second frequency greater than the first frequency and at a voltage level less than that of the first voltage level to maintain the switched devices in the low resistance state upon removal of the thermal image.

An example image sensor may include pixels that each include a photodiode to receive image light and produce image charge in response, a floating diffusion to receive the image charge, a transfer gate to couple the photodiode to the floating diffusion in response to a transfer control signal, a reset gate to couple a reset voltage to the floating diffusion in response to a reset control signal, and a boost capacitor coupled between the floating diffusion and a boost voltage source, wherein, during a precharge operation, the boost voltage is provided to the boost capacitor for a portion of time the transfer gate is enabled and while the reset gate is disabled.
