Abstract: An electronic camera having an image sensor responsive to a preliminary exposure for producing an output signal, a computing circuit for computing a proper exposure condition on the basis of the signal, and a compensating circuit for compensating the exposure value in accordance with the proper exposure condition is provided with a compensation prohibiting circuit for prohibiting the exposure compensation by the preliminary exposure by taking into account the object condition and the exposure mode.

Abstract: A video player module (16) is detachably mounted in a housing (12a) of an airline passenger seat console (12), and has a cavity (16c) which opens in the forwardly facing direction (14) of the seat (10). A video monitor (22) is pivotally attached to the end of an arm (26) which extends from the console (12), and is movable between a viewing position above the console (12) and a stowed position inside the cavity (16c). The monitor (22) is positively prevented for moving rearwardly past the viewing position and possibly striking a passenger sitting in the seat (10) in response to inertial forces resulting from abrupt motion of the aircraft. The arm (26) is pivotally attached to the console (12) by a durable disc clutch (34) which is capable of securely holding the arm (26) and monitor (22) in the viewing position, and allowing the arm (26) and monitor (22) to be moved between the viewing and stowed positions against a constant and optimal value of resisting torque.

Abstract: An image pickup device is capable of picking up images while electrically enlarging the same. In enlarging image pickup, horizontal transfer pulses H.sub.1, H.sub.2, a reset pulse R, a clock signal CLK, sampling pulses SP.sub.1, SP.sub.2 and so on having the periods twice as long as those in the normal image pickup are generated from a horizontal transferring circuit in a timing pulse generating circuit. Thereby, charges stored in a CCD image sensor (6) are horizontally transferred by these signals. A vertical transfer circuit sets vertical transfer pulses V.sub.1 to V.sub.4 at arbitrary timings during 1H of a video period to output the same once in every 2H and outputs high speed vertical transfer pulses in two periods in a vertical blanking period and outputs a reading pulse TG between the first high speed vertical transfer period and the next high speed vertical transfer period. The charges stored in the CCD image sensor are then transferred in the vertical direction in response to these signals.

Abstract: An voltage monitoring system including means for providing a voltage from a current and for reducing the voltage. The system also includes means for integrating the current. The integrating means provides an output which increases from an initial condition at a rate proportional to the voltage. The system further includes means for sensing when the output of the integrating means is above a predetermined level and for resetting the integrating means to the initial condition. Additionally, the system includes means for indicating when the output of the integrating means exceeds the predetermined level.

Abstract: A photovoltaic device is provided that is adapted to monitor an "on-line" light source and respond to on/off changes of the source while at the same time being adapted for visual inspection of the light. The device is adapted for incorporation into a remote warning system which may also be able to activate remedial measures to correct deviations signalled by a change in the "on-line" light status.

Abstract: A composite core transformer has a high permeability segment and a low permeability segment such that a saturable portion of the core is used to control RF energy coupled from a receiving antenna to a radio receiver. Transformer input and output windings are wound on the low permeability segment of the composite core. A control winding is wound on the high permeability segment of the core and receives an automatic gain control signal from a radio receiver. The resulting radio receiver has high resistance to overload and an extended dynamic range of automatic gain control.

Abstract: A silicon integrated circuit includes a centrally located Hall element having an annular moat region surrounding the Hall element to isolate it from built in stresses in adjacent parts of the integrated circuit. The moat comprises at least one annular isolation wall, but preferably two concentric isolation walls. This moat construction also leads to a reduction in dependency of Hall element symmetry upon process variables.

Abstract: A disc-type semiconductor mounting arrangement is provided with force distribution spacers. One side of each spacer contains a counterbore which prevents contact between the center of the spacer and other elements of a stack of semiconductors and associated heat sinks and bus bars. Compressive force applied to the assembly is thereby distributed across the semiconductor pole area.
