Abstract: An electrical assembly comprising a circuit board an electrical device, and a heat dissipation device. The electrical device is capable of emitting thermal energy and electromagnetic interference (EMI). The electrical device is secured to the circuit board. The heat dissipation device is secured to the circuit board and is in thermal communication with the electrical device. The heat dissipation device also includes a continuous EMI fence and a plurality of fins disposed in a matrix orientation. The fins are spaced from one another to allow for efficient heat dissipation and have a substantially square cross-sectional shape.

Abstract: An electronic assembly includes a housing having a first portion and a remaining portion. The first portion includes a surface forming an outer wall of the housing. The electronic assembly also includes a component such as a CD ROM drive, for example, that may be mounted on the first portion of the housing. Further, at least one additional component, such as a motherboard, may be mounted on the remaining portion of the housing. The first portion of the housing is rotatably attached to the remaining portion of the housing. When the first portion of the housing is rotated into a closed position, the component and the additional component are positioned adjacent to each other. However, when the first portion of the housing is rotated into an open position, the component and the additional component are moved away from each other to allow access to the additional component.

Abstract: The disclosed device is directed towards an air inlet bezel. The air inlet bezel comprises a body and a system air inlet grill contiguous with the body. A power supply air inlet grill is contiguous with the body and proximate to the system air inlet grill. A pair of ejector tabs is formed in the body. The ejector tabs are configured to manually couple the air inlet bezel to a power supply assembly.

Abstract: A cable arm for a computer system includes a first leg, a second leg hingedly joined to the first leg, and an enclosure flange hingedly joined to the second leg. The cable arm further includes a rack flange, hingedly joined to the first leg, capable of being attached to a rack for holding the computer system, an enclosure bracket capable of being attached to the computer system and capable of being attached to the enclosure flange, and a hook, extending from the second leg, capable retaining a cable attached to the computer system.

Abstract: A computer housing which includes a chassis that has a first compartment and a second compartment. The first compartment includes a first electronic assembly and a first fan that creates a flow of air through the compartment to create a compartment pressure that is less than an ambient pressure. The second compartment contains a second electronic assembly and a second fan which produces a flow of air that creates pressure within the compartment that is greater than the ambient pressure. The housing also contains an inner wall which separates the first compartment from the second compartment to inhibit air flow between the compartments.

Abstract: The present invention is a computer housing with a low noise cooling system. The computer housing is comprised of two principal members, a cover and a base. Both a left surface and a right surface of the cover are perforated with vents to allowing the passage of air through the housing. The base additionally incorporates two air intake holes with a power source for the computer disposed over these air intake holes. The passage of air through the housing is facilitated through the use of three fans. These three fans are attached directly to the power source, and each of these fans operates at a different fan speed. The fan speeds are additionally adjusted in response to the outside ambient temperature. In operation, air enters the computer housing of the present invention through the vent array on the left surface of the cover, and the air intake holes in the base.

Abstract: A modular circuit board placement system is disclosed that provides for flexible placement of daughterboards, for minimal bus signal path lengths between motherboard and daughterboards, and for ease of installation and removal of daughterboards. The placement system employs dual height bus connectors, a stepped back panel, easy to engage and disengage dual height card retainers, filler panels that also function as module mounts, and multipurpose circuit card handles that facilitate removal of daughterboards. Daughterboards have a two-tier staggered arrangement above the motherboard. Each daughterboard has a signal transfer end that electrically connects to the motherboard through one of the dual height bus connectors, and a back panel connector end that couples to the back panel with an accessory connector or with a filler panel that functions as an electromagnetic interference shield.

Abstract: A quick connect modular unit retainer assembly for easily installing or removing a modular unit such as a disk drive in a computer housing. Threaded inserts having elastomer sleeves are mounted to the modular unit. The insert assemblies are inserted first vertically, and then horizontally, into L-shaped channels on bosses projecting upward from the computer base. Cooperating fingers extending downward from a pivoted computer cover are maneuvered into the L-shaped channels adjacent to the insert assemblies, thereby locking the insert assemblies, and hence modular unit, into place.

Abstract: An electronic unit retention system is shown. With the present invention, electronic modules are kept retained within a system housing so long as power supplied to the module. A bracket is mounted within a module along its back wall. One or more guide pins extend from a back plane of the housing towards the center of the unit. A solenoid is mounded on the bracket and connected to the module's internal power supply. The solenoid is connected to the power supply in such a way that whenever power is supplied to the module, the solenoid is energized. The solenoid is designed such that when power is disconnected from the solenoid, and the solenoid is de-energized, the solenoid pin in the solenoid is withdrawn into the solenoid body. When the solenoid is energized, the solenoid pin extends. The solenoid is mounted on the bracket in such a way that when the pin is extended, it interacts with the guide pin and prevents the module from being moved. The solenoid pin contacts the guide pin tangentially.
