Abstract: A bulk modulus elastomeric element is employed in the present invention. The material from which the invention is fabricated is formed as a sheet, which has a plurality of channels that run through, or partially through it. The holes in the sheet are angled such that the remaining material may be of a parallelogram shape. The top and bottom surfaces of the particular element may be rectangular, circular, hexagonal, or other shapes, since the shape of the end surface is not important to the invention. An edge of an upper end surface is displaced from a remote edge of the lower surface so that a vertical line from one edge normal to the upper surface, is displaced from the remote edge of the lower surface, so that it preferably does not intersect any part of the lower surface when no forces are applied to the surfaces. However, in some instances, under load, a small overlap at the cross-sectional areas of the upper surface and lower surfaces, may be desirable.

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 circular cylindrical container having sealed ends provides a device for dissipating mechanical forces. The container is filled with particulate material and has circular wheel-like structures having rims and spokes located in the interior of the container in which the rim circumferences of the wheel-like structures increase as they are located further and further away from the centroid of the container along the elongated axis of the container toward one of the sealed ends.

Abstract: A cable management slide system that flexibly follows the displacement of a module into and out of a cabinet housing to allow the rear access ports of the module to be connected to adjacent modules through connectors that are laterally and forwardly positioned with respect to the module. Use of cable management slides on opposite sides of the modules allows one to physically isolate the power cable for the module from the data line of the module thereby inhibiting or preventing electrical interference therebetween.

Abstract: An image alignment system for rear projection in which a portion of the normally changing pixel pattern contains a pixel reference mark, which appears in each of the side-by-side pixel images projected onto a screen. A camera having a field of view large enough to encompass the pixel reference mark of each of the images on the screen captures the location of the pixel reference marks to enable a computer to determine the coordinates of the each of the pixel reference marks and generate a deviation signal represented of the visual misalignment of the side-by-side images. A drive member controllable by the deviation signal from the computer repositions one of the side-by-side images with respect to the other to thereby align the images to produce a single visually seamless image. The camera and computer can continually monitor both of the pixel reference marks to continually generate a deviation signal so that the side-by-side images can automatically be brought into a single visually seamless image.

Abstract: An energy dissipation system for limiting forces applied to object; includes a piston rod that extends out of a pneumatic cylinder which contacts the object, the piston rod is forced from its initial position against a return spring and air is forced into an air line. The force transmitted to the object is consumed by an energy transformation device that responds to the air in the air line. [One such energy transformation device as an air accumulator, which is coupled to the air line trough a check valve. An orifice or release valve, releases air up a predetermined flow rate so that the linear motion of the protected object is transformed into work, which is dissipated.] [Another] The energy transformation device consists of an air-driven motor coupled to a heavy flywheel [through] that is driven by the motor.

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.
