摘要： An image sensor is disclosed which is capable of handling large amounts of signal charge with small shift registers. The image sensor includes photoelements 10 in which charge is accumulated in response to sensed conditions; electrically-controllable transfer gates 20 adjacent the photoelements 10 for controllably releasing the charge from the photoelements; vertical shift registers 30, separated from the photoelements 10 by the transfer gates 20, for receiving the charge from the photoelements, and a scan generator connected to the barrier 20 for supplying a series of pulses thereto, a group of pulses being required to release all of the charge accumulated in the photoelements 10.

摘要： On-the-fly video processing to implement two-dimensional algorithms is performed without a frame buffer or ran dom-access memory, by using CCD delay elements (100, 102) whose clock rate is controlled by a phase synchronizing loop (118, 120, 122, 124), to achieve precise vertical alignment of pixels where the chosen alogrithm requires.

摘要： A liquid filled differential pressure detector comprises two pressure sensors. Each sensor is constructed of one or more capsules, which are pairs of diaphragms sealed at their periphries. The innermost diaphragms are interconnected by a tube which contains a rod assembly. The interior of the sensors and interconnection tube form a sealed volume filled with a incompressible liquid. The rod assembly contacts the outermost diaphragm of the sensors and is displaced by expansion and contraction of the capsules caused by a differential pressure change against the outer surface of the sensors. The motion of the rod assembly is transformed into an electrical signal to indicate the pressure measurement. The apparatus is symmetrical about the center point of the tube to reduce error caused by the fluid's thermal expansion by causing equal and opposite forces to cancel, thereby preventing motion of the rod assembly. An overpressure condition results with one sensor completely collapsing with one diaphragm bottoming out against the other, but causes no damage to the capsules due to complementary facing of the diaphragm pairs. The compliance of the diaphragms is chosen to be small enough to cause any gaseous bubbles to be driven into solution during the initial prepressurization of the fluid, ensuring its incompressibility. In a second embodiment, the rod assembly is replaced with a core assembly located at the midpoint of the tube, suspended in a magnetic fluid which separates the incompressible fluid into two identical volumes. The motion of the core assembly, which is due purely to the displacement of the incompressible fluid, is transformed into an electrical signal to indicate a pressure measurement.

摘要： A jam resistant, low-cost data link, wherein short burst messages are frequency-hopped on a message-by-message basis. The data link includes a transmitter and a receiver which initially are set at a common, predetermined frequen cy. The message transmitted during each burst includes encrypted data identifying the frequency at which the next message will be transmitted to enable the receiver to tune to that frequency. If the initial transmission is jammed, the transmitter and receiver are preprogrammed to change to a preset back-up frequency. The receiver will request retrans mission before the next transmission frequency is changed if a received message is garbled.

摘要： An improved AGC circuit utilizes a two-stage amplifier/ attenuator wherein each stage of the circuit comprises at least one JFET having its gate biased by a buffered feedback voltage derived from both the signal and control voltages. The dynamic range of each stage can be increased by paralleling additional JFETs in each stage. The buffers in the feedback loop are broadband to allow control down to DC, provide isolation between each stage and the signal output and help to minimize the amount of signal offset introduced into the signal by the control voltage.

摘要： A frequency-hopping datalink for providing communication between a base station, relay unit and multiple remote units utilizes time-division multiplexing and transmits information signals containing information relevant to the next frequencies of transmission. Signals from the base station are transmitted on a first frequency to a relay unit which retransmits the signals on a second frequency to a group of remote units. The information signal from the base station contains information concerning the frequencies of the next transmission and the time slot allotted for the remote units to respond. The remote units respond back at the first frequency which is received by the relay unit and rebroadcast to the base station at the second frequency. The first and second frequencies are changed after each message in accordance with a pseudo-random sequence generated either at the base station (and transmitted in encrypted form) or by means of a pseudo-random sequence generated at each remote unit and the relay unit, whose initial state is reset by an internal or externally derived time reference and whose pattern is determined by an internal key.

摘要： A high speed asynchronous data multiplexer/demultiplexer system which multiplexes a quantity of independent and asynchronous data streams into a single packetized data stream and then demultiplexes and presents the original input signals at a remote site in their original form is described. The output bit rate of the demultiplexer is generated responsive to the packet arrival frequency of data from each particular channel and the output buffer fullness of that channel. This process reduces the amount of processing required, such that the effective bandwidth of the system can be greatly expanded.

摘要： A brake apparatus is provided for tape recorders, particularly of the coaxial reel type, in which a single brake pad, mounted on a brake arm, engages a pair of adjacent coaxially disposed drive wheels for coaxial tape resls. The brake arm is biased by a spring into braking engagement with the drive wheels. A solenoid is operable to withdraw the brake arm, thereby disengaging the brake, when energized. The solenoid is controlled to be energized whenever a drive motor for the tape reels is powered, and to be deenergized when the drive motor is not powered. The disclosed structure provides automatic braking for the tape reels whenever the drive motor loses power or is shut off, thus providing positive mechanical braking both in a power loss condition and in a parking condition for the tape reels.
