  • Publication number: 20120145785
    Abstract: A scope assembly for use with, a projectile firing device including an erect image telescope mounted upon the device. The telescope includes a housing with a series of spaced apart lenses, a reticle display field being disposed along an optical path established within the telescope and which is viewable by a user. A laser range-finding scope is housed within a component in parallel disposed fashion relative to the erect image telescope, the range-finding scope incorporating a microprocessor and timer in operative communication with a pulse generator and an infrared projector. The distance to the target is measured by the laser, pulse detector, and timer. The data is transmitted to the microprocessor which determines the vertical position required to hit the target. The compensated target aimpoint is then illuminated in the reticle display field as a horizontal line.

  • Patent number: 5446661
    Abstract: A method and system for discriminating motor vehicle crashes to actuate a safety restraint (10) utilizes an optical vehicle occupant position detector (12) to generate data (22) representative of the position of an occupant relative to fixed structure within the vehicle. The data (22) is subsequently used by a signal processor/discrimination unit (26) as criteria for a parameter based crash discrimination analysis, and for adjusting parameters of the discrimination analysis, such as changing the discrimination threshold values. The occupant position data optimizes the discrimination analysis used in the system (10) due to the system's ability to customize the discrimination analysis in real time to match actual conditions of a vehicle occupant. Occupant position is determined by detecting the relative intensity, or average of scattering angles of a light beam (34) reflectively scattered by the occupant (24).

  • Patent number: 4731610
    Abstract: An electronic matrix system and method for rapidly storing and efficiently retaining electric charge in selected ones of a plurality of storage elements are disclosed. Each storage element is addressable through a pair of parallel row select address lines and a column address line. A pair of threshold devices are coupled in nonopposing relation between the row select address lines and the storage element is coupled between the common node of the threshold devices and the column address line to which charging potential is applied. During the charging of the storage element, operating potentials which are substantially equal and opposite in polarity are applied to the row select line pair to forward bias both threshold devices and thereafter operating potentials which are also substantially equal and opposite in polarity are applied to the row select line pair to back bias both threshold devices to provide retention of the charge in the storage element.

  • Patent number: 4715685
    Abstract: A dynamic memory array includes plural sets of spaced apart address lines and storage locations defined by cross-overs of members of the plural sets of address lines. At each storage location a charge storage means is coupled to a threshold means. The charge storage means are addressable through the threshold means by the application of selected potentials to the plural sets of address lines. The charge storage means and the threshold means can be formed as vertically arrayed, deposited, layers of semiconductor materials, and preferably from amorphous semiconductor alloys. Also disclosed is a light influencing display having an improved bidirectional threshold isolation means.

  • Patent number: 4678282
    Abstract: A light influencing display is provided which has a plurality of pixel group, each pixel of which includes a first electrode formed on a first surface and an opposing, second electrode formed on a second surface. A separate three terminal control device of deposited semiconductor material is formed on the first surface in association with each pixel. Each control device has a control terminal and two current path terminals, a first of which is connected to the first electrode of the control device's associated pixel. A voltage supply lead is formed on the first surface in association with each pixel group, and is connected to the second current path terminals associated with its pixel group. Similarly, a control lead is formed on the first surface in association with each pixel group, and is connected to the control terminals associated with its pixel group.

  • Patent number: 4679085
    Abstract: An apparatus for displaying in real-time a previously recorded video sequence includes a main memory wherein digitized video gray-scale information is stored for selected non-interlaced fields of video images to be displayed. The memory unit is formed of interconnected substrates. Each substrate is a ROM which includes storage elements and a layer of amorphous silicon alloy which forms an array of diode isolation elements. Column select and read-out circuitry as well as row select circuitry for each of the substrates are formed, on each corresponding substrate, utilizing the same amorphous silicon alloy. Digitized fields of presorted information are read out and stored in pairs in an interpolator circuit which is used to form interlaced fields to be displayed timewise between the digitally stored fields. The digitized fields are converted by a digital-to-analog converter and added to sync signals to form a composite analog video signal adapted to drive a raster scan display unit.
