Abstract: The present invention is an information processing system. The information system comprises a housing, a card insulator, and a card insulator guide. The card insulator comprises a planar portion, a handle portion coupled to the planar portion, the handle portion including a securing element for securing the card insulator to the housing. The card insulator guide is coupled to the housing wherein the card insulator guide comprises at least one slot for receiving the card insulator and a retainer lid hingedly coupled to the at least one slot for securing the card insulator to the card insulator guide. Through the use of the system in accordance with the present invention, the card insulator is coupled to the information processing system in a more secure fashion thereby preventing the card insulator from popping out of position as a result a shock or vibration to the information processing system.

Abstract: A computer chassis in accordance with the present invention is disclosed. The chassis includes a first body, a second body, and an electromagnetic shield coupled between the first body and the second body. The shield includes a plurality of dimples and a plurality of valleys for providing an electromechanical seal when the shield is placed in an interference condition. The chassis shielding system utilizes a shield with a design that is inexpensive to manufacture, is structurally sturdy, and simple to implement in an interference environment. In a preferred embodiment, the shield is provided for inserting between a circuit card mounting bracket and a computer chassis. The improved shield design incorporates special features including a plurality of dimples and a plurality of valleys, strategically located for providing improved adjacent surface contact and enhanced shielding from unwanted radiation.

Abstract: A component assembly in accordance with the present invention is disclosed. In a first aspect, the assembly includes at least one component and a bracket for holding at least one component. The bracket has a first side, a second side, and formed features for holding at least one component to the first side of the bracket. The assembly includes a wire spring assembly for securing at least one component to the second side of the bracket. In a second aspect, the component assembly comprises a first component and a second component. The component assembly further includes a bracket for holding the first and second components on the first and second sides of the bracket. The first and second sides of the bracket are oppositely disposed to each other. The bracket includes formed features on the first and second sides for retaining the first and second components.

Abstract: A slot-type processor and one or more cache modules are incorporated into a vertically oriented, multiple chip module (CM) that is mounted to a printed circuit board. The MCM operates at ultra high frequencies and very high temperatures. Each component of the MCM has a heatsink, a thermal plate, and a series of mounting clips and screws which combine to dissipate heat. The heatsinks and thermal plates generate most of the electromagnetic interference (EMI) since they are not attached or grounded to the board. A series of alignment posts extend from the board and are used to individually and slidably mount each of the components to the board. Each thermal plate is grounded to the posts with grounding clips. The clips maintain contact with the thermal plate through wiping elements. Additional pressure is applied to the wiping elements through a post retaining bracket. The components are fully seated and retained in position with retaining cams.

Abstract: A ribbon loading system for a printer of the kind having a moveable printhead carrier establishes a ribbon loading position for the carrier at one end of the carrier travel axis. In response to an operator initiation, the printhead carrier is driven to the loading position where the ribbon cartridge is operator mounted at a fixture adjacent the printhead. The cartridge includes a path defining section that extends to arrange a loop of ribbon around the distal side of the printhead, effectively threading the ribbon. Subsequent carrier movement is selectively coupled to the ribbon to provide ribbon drive motion.For a preferred cartridge implementation, the path defining section is detachable to travel with the printhead carrier and includes ribbon guides for defining at least a portion of the ribbon path around the printhead during printing. The preferred detachable section is held to a bulk ribbon supply section of the cartridge by a catch which is automatically released by mounting the cartridge.
