    Abstract: There is produced for each location of an image sensor, such as an X, Y addressed photodiode array or a self-scanned charge transfer array, a signal indicative of the dark current amplitude at that location. During operation of the sensor, when a location producing excessive dark current is read out, rather than using the signal stored at that location, there is instead substituted a signal level which is the average of that stored in adjacent locations of the sensor.

    Abstract: Overlaid alignment and mounting of a series of grid electrodes in spaced apart relation to a plurality of corresponding indicia electrodes on a substrate member of a display device is provided. A grid retaining member includes a series of grids retained by common opposing sides of a flex removable frame. Depression channels are provided at the retained ends of the grids whereby mounting pads are provided for accurately spacing grid and indicia surface portions, and whereby the various ones of the series of grids may be secured to corresponding ones of a series of terminal pads on the substrate. Protrusions from a base carrier member engage the peripheral walls of the various other members to provide alignment of grid surface portions with corresponding ones of the indicia electrodes. A method is described in which the members are internested in overlaid sequence above the base carrier member whereby fixed spaced-apart alignment of the grid and indicia surfaces is accomplished and whereby contact between various corresponding ones of the mounting and terminal pads is achieved. The respective grid mounting pads are then secured to corresponding ones of the terminal pads along the substrate member. The opposing side portions of the frame are thereafter flexibly broken away to provide electrical isolation of the grid electrodes.

    Abstract: The filter is of a bridged-T construction, and includes a pair of semiconductor rectifiers in back-to-back relationship. An oscillation voltage is applied to the junction of the rectifiers to vary their reverse biases and the junction capacities they exhibit. The variations in notch frequency which result are selected to overlap possible drift in filter tuning and provide continued signal rejection in the presence of such changes.

    Abstract: A metal solvent is melted and a semiconductor material is added to the molten metal solvent when the metal solvent is at approximately the temperature at which the deposition is to start. When the semiconductor material is in the metal solvent long enough to allow enough of the semiconductor material to dissolve in the metal solvent to exactly saturate the metal solvent with the semiconductor material the substrate is brought into the solution. Other materials, such as conductivity modifiers and composition modifiers, may be added to each of the solutions either with the semiconductor material or during the deposition process. Apparatus comprises a boat having a plurality of spaced wells in its upper surface. A first slide for bringing a substrate into contact with molten material in the boat forms the floor of the boat wells. A second slide for adding materials (e.g. semiconductors and dopants) to molten material is spaced from the floor adjacent to but slightly below the top surface of the boat.

    Abstract: A system for comparing with a preset constant a ratio of the average value of a variable to the average value of its time derivative over a specified time interval. The system is embodied in a digital circuit, consisting of counters and logic gates, performing both an averaging function and a ratio comparison function without requiring division by a variable. One embodiment of the system finds particular utility in the field of collision avoidance of airborne vehicles wherein it can be used to give early warning of a potential collision by comparing the time to impact, Tau, (range over range rate) to a preset critical time.

    Abstract: A boost voltage delay circuit for deflection circuit utilizing trace and commutating switches to generate deflection current in a deflection winding. A supply voltage boost circuit derives voltage from an inductor coupled between the direct current voltage supply and the commutating switch, boosts and regulates it, and supplies this regulated boost voltage to the commutating switch. The boost voltage delay circuit monitors the commutation switching action by rectifying voltage variations appearing across the inductor to charge an R-C circuit for several cycles of commutation switching action before the voltage across the R-C circuit rises sufficiently to turn on a transistor which enables the boost voltage circuit to supply boost voltage to the commutating switch. Commutation loss due to failure of the commutating switch to become reverse biased under applied boost voltage is thereby prevented.
