    摘要: In an array of charge injection device (CID) detectors, integer amplification is incorporated into each respective detector of the array. The amplifier for each CID detector in the array performs multiple nondestructive readouts. This provides a gain of N amplification of the signal charge in that detector wherein the signal charge is accurately replicated in a separate charge storage well defined by a magnitude capacitor coupled to the detector. Thus, at the end of the readout process, this separate well contains charge equal to N times the signal charge, N being the number of nondestructive readout cycles in the readout process.

    摘要: Coherent light is projected through a scattering medium. The light emerging from the medium is a superposition of a multitude of scattered wavelets, each of which represents a specific scattering path. These wavelets are projected onto a diffuse reflecting surface (the viewing plane of a two-dimensional photodetector array) where they interfere with each other, giving rise to a speckle pattern. By introducing a focused ultrasound pulse into the medium, the position of the scatterers are changed at a known location (probe region) in the medium, and this causes a change in the speckle pattern. By comparing speckle images before and after the scatterers are moved, the light absorption properties of the probe region can be measured even though multiple scattering interferes with direct imaging of the region.

    摘要: A mobile tracking unit capable of operating in a power-starved environment for a vehicle tracking system includes a navigation set for generating data corresponding to a respective vehicle position. The navigation set is periodically energized at a selected activation rate F.sub.G while the vehicle is moving to generate the vehicle position data. The tracking unit includes an electromagnetic emitter which is capable of transmitting the vehicle position data and which is periodically energized at a selected activation rate F.sub.EM while the vehicle is moving to transmit at least the vehicle position data. A motion sensor is employed for generating data indicative of vehicle motion. A tracking unit controller receives the vehicle motion data and controls the navigation set and the emitter based upon the vehicle motion data so that when the vehicle is stationary each of activation rates F.sub.G and F.sub.EM can be respectively decreased by a predetermined factor, thus reducing the overall power consumption of the tracking unit. The tracking unit controller is further designed to return to activation rates F.sub.G and F.sub.EM upon the motion sensor sensing renewed vehicle motion, thus avoiding loss of vehicle position data during times of renewed vehicle motion.

    摘要: An apparatus for convening vibratory motion along a predetermined vibration axis to electrical energy comprises an enclosure having first and second opposite walls substantially parallel to one another. A magnet carrier structure in the enclosure also has first and second opposite walls substantially parallel to one another. A pair of springs suspend the carrier structure in the enclosure so that corresponding first walls and corresponding second walls, respectively, face one another with a predetermined spacing therebetween. The springs allow reciprocating movement of the carrier structure relative to the enclosure only along the vibration axis in response to the vibratory motion. Separate magnet sets, each comprising a row of permanent magnets, are attached to a respective outer surface of the first and second walls of the carrier structure for producing a respective magnet flux. Separate coil assembly sets, substantially configured and dimensioned like the magnet rows, are attached to a respective inner surface of the first and second walls of the enclosure and are situated to be magnetically coupled to a corresponding one of the separate magnet sets in order to produce electrical current due to magnetic flux changes whenever the carrier structure and the enclosure move reciprocally with respect to one another along the vibration axis.

    摘要: A coherent light phase detecting focal plane array uses a bulk substrate of a first conductivity-type semiconductor, with a layer of the opposite conductivity-type of that semiconductor formed into an array of CTD cells each storing charge converted from optical photons impingent upon the layer, when positioned in the focal plane of apparatus in which the array is used. Surrounding each cell are four FET structures which separately and individually collect the charge samples during an associated different one of four sampling periods, corresponding to the four quadrants of a two-dimension phase space (+I, +Q, -I and -Q samples). Each FET has five gate electrodes, so as to provide five individual regions for storage and manipulation of the photo-induced change during acquisition, readout and disposal. A correlated-double-sampling form of readout provides separate in-phase I axis video information and quadrature-phase Q axis video information, from which a determination of the amplitude and phase of the light impingent upon each pixel can be made.
