Abstract: A switch, especially for heavy duty vehicle applications, utilizes solid state circuitry and a low voltage, low current touch pad switch, where the switching occurs directly on a printed circuit board and bulky wire terminations are eliminated. The switch includes a rocker, which pivots at its center point fulcrum causing the switch lever, housed inside the switch and attached to the rocker, to move in a particular direction. The configuration of the lever is such that the extending ears on opposite sides press against the elastomer seal and move a carbon contact against the integrated circuit traces on a printed circuit board, completing an electrical circuit. This condition occurs for either directional movement of the rocker. Housed within the lever is a spring-loaded plunger fitted with a roller (wheel) at its end. The roller rests on a predesigned detented ramp located as an integral part of the switch insulator.

Abstract: An EMI-efficient system for mounting internal peripheral devices such as disk or tape drives inside a computer enclosure so that the drives may be removed and replaced easily. A drive bracket guide is mounted to a computer enclosure chassis, a peripheral device is mounted to a drive bracket, and the drive bracket is inserted into an opening of the drive bracket guide. A socket support disposed at the end of the bracket guide opposite the opening fixedly supports a socket in position for receiving a mating socket on the drive. A locking insertion/ejection mechanism is coupled to the bracket and facilitates engagement/disengagement of the two sockets in the rear of the assembly. The bracket guide may be integrally formed on side walls of a drive cage to reduce potential for leaks of electromagnetic energy from the enclosure and to facilitate the creation of numerous bracket guides in a stack arrangement for housing multiple drives.

Abstract: A switch, especially for heavy duty vehicle applications, utilizes solid state circuitry and a low voltage, low current touch pad switch, where the switching occurs directly on a printed circuit board and bulky wire terminations are eliminated. The switch can be directly coupled to one or more microprocessors without the need to step down the voltage or current. The switch includes a rocker, which when one end of the rocker is pressed, the rocker pivots at its center point fulcrum causing the switch lever, which is housed inside the switch and attached to the rocker, to move in a particular direction. The configuration of the lever is such that the extending ears on opposite sides press against the elastomer seal and move a carbon contact against the integrated circuit traces on a printed circuit board, completing an electrical circuit.

Abstract: A printed circuit board and bulkhead assembly with I/O connectors that may be slidingly mated with a rear panel bulkhead frame of a computer chassis without removing the rear panel and without having to remove any mounting hardware. The I/O connectors are attached to the bulkhead assembly in such a manner that the I/O connectors clear the rear panel bulkhead frame when the bulkhead assembly is being slidingly mated with the rear panel bulkhead frame. The I/O connectors extend through the rear panel bulkhead frame once the bulkhead assembly is mated with the rear panel bulkhead frame. When fully installed, the bulkhead assembly and the rear panel bulkhead frame create a barrier against EMI/RFI radiation emissions escaping the computer chassis.

Abstract: An EMI gasket formed from a conductive sheet having a hole therein. A first set of conductive fingers is disposed along the periphery of the hole protruding away from the conductive sheet on the front side. A second set of conductive fingers is disposed along the periphery of the hole protruding away from the conductive sheet on the back side. The first conductive fingers are alternately interleaved with the second conductive fingers. Each of the first conductive fingers includes a first and a second portion defined by a bend. The first portion is disposed in the plane of the sheet. The second portion is disposed in a plane orthogonal to the plane of the sheet. The first conductive fingers operate to engage a conductive portion of a panel. The second conductive fingers operate to engage a conductive portion of a component. The conductive sheet and the first and second sets of conductive fingers are made of spring steel.

Abstract: An electronic device having a printed circuit board that must align with and connect to various devices on more than one edge of the printed circuit board. The printed circuit board having an isolation slot that creates a peninsula connection region near one edge of the printed circuit board to enable the printed circuit board to be readily aligned inside the electronic device with the various devices that the printed circuit board mates with. The present invention may also include a travel limit bracket attached to the printed circuit board on either side of the isolation slot in order to limit the amount of travel and twisting of the peninsula connection region. The printed circuit board may also include insertion guide that guide the printed circuit board as it is being mated with a front panel of the electronic device.

Abstract: In an apparatus for preparing flavored frozen comestibles, the improvement comprising means for directing a stream of cold air at the surroundings of the equipment in which the product is being prepared, said air being sufficiently cold to reduce the temperature of the surroundings to about 45.degree. F.

Abstract: The present invention is a method and apparatus for cooling a frozen comestible plasticizer apparatus with a heat exchanger pan over a freezer, protecting the freezer from extraneous matter filling in, while providing a cool circulatable environment to cool the auger and cup of the apparatus to help avoid bacterial growth and minimize the need for cleaning of the apparatus.

Abstract: An apparatus for processing frozen comestibles has a cup for receiving a frozen comestible and a rotatable auger mounted for movement relative to the cup. The cup is moved to the auger to create a pocket in the frozen material in a first relative movement and mixes the frozen material with an added flavoring and extrudes the mixture from the cup in a second operation. A counter is provided which counts only the number of second operations of the apparatus.
