Abstract: A cross elastomer mount comprising a body composed of an elastomer and having a plurality of legs, a first platform for supporting a first member and a second platform for supporting a second member, a plurality of rigid platform arms pivotally attached to the platforms, and a plurality of hinges pivotally attaching the rigid platform arms to the legs of the cross elastomer mount whereby the plurality of legs bow or arc under a shock and vibration force to allow the cross elastomer mount to attenuated the forces while providing a tension and shearing resistance to the shocks and vibrations.

Abstract: A dual hemisphere elastomer mount having a first hemisphere composed of an elastomer and having a polar region and a base region with the polar region of the first hemisphere having a circumference smaller than a circumference of the base region of the first hemisphere; and a second hemisphere composed of an elastomer having a polar region and a base region with the polar region of the second hemisphere having a circumference smaller than a circumference of the base region of the second hemisphere, the first hemisphere securely attached to the second hemisphere at the polar region of the first hemisphere and at the polar region of the second hemisphere creating a hour-glass shaped body whereby the elastomer mount can support a housing while attenuate shocks and vibrations.

Abstract: A shock isolator for use in a compressive mode comprising a pyramid-shaped elastomer having a cavity therein with the pyramid-shaped elastomer having a base supporting a set of triangular shaped sidewalls that each terminate in a apex with the triangular shaped sidewalls cantilevered from the base to jointly terminate at a pyramid-shaped apex to create a one-piece elastomer mount so that a force applied to the pyramid apex is transmitted to the base through an offset axis while shock and vibration forces are attenuated by the shear resistance of the shock isolator.

Abstract: A modular shock isolator and method of isolation of components of a system with multiple modular shock isolators arranged to provide different damping and vibration characteristics than an individual modular shock isolator. In one mode, a modular shock isolator having a base with legs extending from each side of the base with each of the legs having a foot that extends outward from the legs with the modular shock isolator either individually mounted to isolate a component or a plurality of modular shock isolators are be ganged, or stacked together to change the shock isolation characteristics of the shock mount formed from the multiple modular shock isolators. A layer of damping material can be sandwiched between layers of elastomers to dampen the natural spring-back of the materials.

Abstract: A molded or non-molded elastomeric shock cell having a base with legs extending from each side of the base with each of the legs having a foot that extends laterally outward from the legs to provide a unitary elastomeric shock cell that can be individually mounted to support plates or a plurality of elastomeric shock cells can be ganged, or stacked together to produce a composite isolator with different shock isolation characteristics. The elastomeric shock cell if mountable in one axis provide tension resistance and if mounted in a bias axis or right angle axis provide tension and compression resistance to shocks to the system.

Abstract: A baffle and screen arrangement for use in a rear projection display system with multiple imagers with the baffle being positionable with respect to the display screen of the console unit so that the baffle can interfere with at least one of the images produced by the imagers to allow the images to visually merge into a single, contiguous image with no halo effect, overlap, or excessive brightness and gaps. In one embodiment the baffle has an irregular, non-reflective light-absorbing surface to further reduce excessive unwanted image light from hitting the display screen and causing unwanted distortion.

Abstract: A shock isolator having a spring members such as a belleville washer for supporting a static weight with the belleville washer toggleable between a support condition and a nonsupport condition with the belleville washer having a collapse force that is sufficiently high so that the belleville washer can support a static load without collapsing in order to normally maintain an elastomer damping material in a condition free or substantially free of static forces. When a dynamic force exceeds the collapse force of the belleville washer the belleville washer toggles to a collapsed condition leaving the elastomer to tensionally respond to both the static and the dynamic forces by expansion and contraction of the elastomer.

Abstract: A compact projector system utilizing a rear projection console with at least one projector and a set of mirrors with each mirror being positionally placed with respect to the rear of the display screen and operating together by bouncing an image carrying light beam which originates from a projector from one mirror to the next within the console and across itself before the image-carrying light impinges upon the rear of the display screen to produce a relatively large, contiguous image thereupon with the at least one projector and set of mirrors being confined in a relatively small console area.

Abstract: A shock isolator having a housing securable to a support structure with the housing containing a bell shaped elastomer having a base secured to the housing and an axially offset apex surface secured to a connector to cantileverly support equipment to be isolated from shock with the cantileverly support of apex surface from the base insuring that any displacement of the connector produces a substantial shearing action in the elastomer to effectively damp the effect of a shock on the shock isolator.

Abstract: A shock isolator comprising a first plate having a set of ridges and grooves extending there along and a second plate having a complementary set of ridges and grooves with an elastomeric sheet sandwiched between the two plates so that when a compressive force is applied to the two plates the elastomeric sheet resist the forces through compression resistance, tension resistance and shear resistance to provide both static support and shock isolation to an object supported by the shock isolator.

Abstract: A rear projection system having a display screen and a Fresnel lens wherein each of the incident faces of the viewing segments old the Fresnel lens are angularly positioned so that incoming light rays, which enter each old the viewing segments at different angles, are reflected by each of the segments so that the light rays emerging from each of the viewing segments emerge in a direction parallel to a v viewing axis to thereby limit luminosity differences in images viewable on the display screen.

Abstract: A process is provided for near real-time or real-time software based scan conversion in a general purpose computer. The general purpose computer receives data via a digital network comprising range scaled and window detected radar video and antenna azimuth data in polar coordinate format according to the Andrusiak et. al. U.S. Pat. No. 5,923,285. The general purpose computer integrates the polar data into a polar buffer prior to conversion to Cartesian coordinates for display. This process de-couples the polar buffer from the coordinate conversion process so that the polar buffer process keeps up with incoming real-time data. The coordinate conversion process is given some portion of the remaining processor bandwidth such that even if it does not keep up with the real-time rate of the radar, it will display all target information. The polar buffer processing involves integration of the new data with old data in the polar buffer in order to preserve target information until it has been displayed.
