Abstract: A sensor-display device comprises an array of transmit-receive modules, each of which comprises a light transmitter, a light receiver, and a memory bank. A modulation driver connected to the light transmitter drives the light transmitter to transmit light. The light receiver creates electric charges from light received by the light receiver. A memory interface connects the light receiver to the memory bank for shifting the electric charges as data from the light receiver into the memory bank, and the memory interface shifts the data as electric charges from the memory bank to the modulation driver to drive the light emitter to transmit light based on the electric charges.

Abstract: A data processing array comprises a plurality of modules, each with a memory, positioned in an array of rows and columns interconnected by a pooling chain that carries data to and receives data from selected ones or groups of the modules. Each modules can also have light modulator elements for transmitting data as light signals and a light sensor for receiving data in the form of modulated light. Pooling switches in the pooling chain between modules open and close the pooling chain lines for selecting and grouping modules. Analog data lines separate from the pooling chain can also carry data to and from the modules. Pooling control lines connected to the switches turn the switches on and off for the selecting and grouping of modules. Module control lines, also separate from the pooling chain, connected to the modules enable various data input, output, and processing by the memory or other components in the module.

Abstract: A system (10) for convolving and adding frames of data comprises a first sensor-display device (14) and a second sensor display device (26). Each sensor display device (14, 26) comprises an array (80) of transmit-receive modules (82). Each transmit-receive module (82) comprises a light sensor element (86), a light transmitter element (84), and a memory bank (90). A radial modulator device (20) is positioned where transmission of light fields comprising frames of data are Fourier transformed. Filters implemented by modulator elements of the radial modulator device (20) convolve the fields of light comprising the frames of data, which are then sensed on a pixel-by-pixel basis by the light sensor elements (86), which accumulate charges, thus sum pixel values of sequential convolved frames of data.

Abstract: An electrical system for measuring humidity which is capable of measurements accurate to +/−6 percent from board to board. The accuracy provided by this electrical system makes it possible to correlate errors in data on backup magnetic tapes to variations in humidity. The electrical system consists of an oscillator whose frequency is dependent on the capacitance of a capacitor used in the circuit. The capacitance value of the capacitor is dependent on the relative humidity. The frequency of the oscillator is translated to a humidity value by an electronic counter and a microprocessor.

Abstract: A small portable power supply is connected to a circuit board comprising a volatile memory unit. The main circuit board power supply is then disconnected from the circuit board, and the board may now be physically moved to another location without the loss of the data contained within the volatile memory. At the new location, another main circuit board power supply may be connected to the circuit board, and the small portable power supply may be disconnected, completing the transfer of the circuit board without any loss of data.
