  • Patent number: 4801799
    Abstract: A fiber optic vibration sensor for detecting vibrations of a reflecting surface located externally of the sensor is disclosed which includes a transparent body, source and return optic fibers fastened to the body, a light collimating lens which forms light emanating from the source fiber into a column which extends in a predetermined viewing direction relative to the body. The sensor is positioned relative to the reflecting surface so that the column strikes the reflecting surface and is reflected back through the lens to a focal point in the vicinity of the end of the return optic fiber.

  • Patent number: 4665440
    Abstract: A system is provided for increasing the operation speed of monolithic sensor arrays by segmenting the output circuitry to provide parallel outputs. Two approaches are described. One is an "on-chip" configuration, and the other, an "off-chip" configuration. In the first case, the transfer shift register (14) is divided into two or more segments, each segment serving a corresponding segment of the sensor array (10). By segmenting the transfer shift register, the transfer rate to parallel processors can be improved. In the off-chip approach, a system of gates (18) are provided to shift the contents of the on-chip transfer shift register (14) into a plurality of smaller shift registers (20), the contents of which are then transferred to multiple data processors.

  • Patent number: 4464756
    Abstract: An improved binary signal discrimination system for demodulating FSK transmitted signals is disclosed which requires that both the mark or binary "1" signal frequency and the complementary of the space or binary "0" frequency be present for a mark signal to be recognized; and, conversely requires that both the space signal frequency and the complement of the mark signal frequency be present for a space signal to be recognized.

  • Patent number: 4201913
    Abstract: An apparatus for introducing a gaseous sample into a mass spectrometer is disclosed which includes a hollow antechamber or cavity disposed between the sample stream and the high vacuum enclosure. Orifice openings are provided in the antechamber which allow the antechamber to communicate both with the high vacuum enclosure and the sample stream. An electrically operated pulsed valve is used to admit a series of small volumes of sample by pulses of controlled duration and frequency such that the sample flow from the antechamber into the high vacuum enclosure can be made to resemble one of essentially constant flow.
