Patent number: 6618247Abstract: A computer may be easily user re-configured between desktop and tower housing orientations, with the computer's front side drive units being horizontally disposed in each orientation, using specially designed drive unit support and a reconfigurable front bezel. A square opening is formed in the front exterior wall of the housing, and the support apparatus includes spaced apart channel structures extending inwardly into the housing from the four sides of the wall opening, with opposing pairs of the channel structures being adapted to slidably receive corresponding projections on opposite side edge portions of the drive units. In this manner, each front side drive unit can be supported at the opening in a first orientation in which the drive unit will be horizontally oriented with the computer in a desktop orientation, or a second orientation in which the drive unit will be horizontally oriented with the computer in a tower orientation.Type: GrantFiled: January 22, 2002Date of Patent: September 9, 2003Assignee: Hewlett-Packard Development Company, LP.Inventors: Francis A.

Patent number: 6307747Abstract: In a computer processor module/heat sink assembly, a spring clip member is used to resiliently hold a heat-generating die portion of the processor against the heat sink. Spaced retaining pins are secured to the processor module and extend through holes in the heat sink, with outer end portions of the retaining pins being captively retained in slots in the spring clip member, and portions of the clip member adjacent the outer pin ends being resiliently deformed toward the outer side of the heat sink to thereby resiliently press the processor die portion against the underside of the heat sink. The clip member may be quickly installed on and removed from the outer pin ends without the use of tools of any sort.Type: GrantFiled: July 8, 1999Date of Patent: October 23, 2001Assignee: Compaq Computer CorporationInventors: Arthur K.

Patent number: 5973918Abstract: A system for automatically electrically connecting electronic components, such as an input/output board and a power supply, with a motherboard includes attaching in a tray with electronic components with a frame. In one embodiment, a tray is pivotably attached to a computer housing frame and a connector extends from the under side of the tray. As the tray is pivoted about its axis, the connector is engaged or disengaged from a connector fixedly mounted on the motherboard. The connector on the motherboard has a flexible funneled opening to facilitate insertion of the pivoting connector. In another embodiment, a tray with electronic components can be quickly disconnected from the motherboard by lifting the tray straight up guided by frame tracks. By lifting the tray, a series of leads mounted on the tray are disengaged from the slot connector mounted on the motherboard. Advantageously, a method for disconnecting electronic components from a motherboard in a computer frame is disclosed.Type: GrantFiled: June 16, 1997Date of Patent: October 26, 1999Assignee: Compaq Computer CorporationInventors: Francis A.

Patent number: 5403208Abstract: A card edge connector for printed circuit boards is disclosed which employs a double-decker design. The connector may have the same length and width as conventional connectors used on Industry Standard Architecture (ISA) personal computers but is deeper. Conventional 8- and 16-bit ISA accessory circuit boards may be plugged into a corresponding socket which is also disclosed herein until they reach a stop upon which they rest, working as they would in an ISA personal computer. 32-bit Extended Industry Standard Architecture accessory circuit boards have a second row of connectors and a notch so they slide farther down into the socket, lining up with a second row of contacts. This design uses less physical space for connectors, allowing more room for logic circuitry on the motherboard.Type: GrantFiled: May 11, 1990Date of Patent: April 4, 1995Assignees: Burndy Corporation, Compaq Computer Corporation, Hewlett-Packard CompanyInventors: Francis A. Felcman, Guy M. Gladden, Robert J. Johnson, Geoffrey G. Moyer, James P. Paschal, Heinz Piorunneck, Douglas M. Thom

Patent number: 5218760Abstract: A supportive ground clip for a computer system board mounted in a computer chassis and a method for installing a grounded printed circuit board in a computer shassis using the supportive ground clip. The supportive ground clip includes a base member for providing a grounding connection with the chassis, flexible support members attached to opposite ends of the base member and ascending vertical members attached to the flexible support members for mounting the supportive ground clip to the computer system board. Each of the flexible support members includes a contact point for providing a grounding connection with the bottom side of the computer system board and each of the ascending vertical members includes a contact point for providing a grounding connection with the top side of the computer system board. The first and second flexible support members are shaped such that compressive forces exerted on the supportive ground clip support the computer system board within the chassis.Type: GrantFiled: May 1, 1992Date of Patent: June 15, 1993Assignee: Compaq Computer CorporationInventors: James H.

Patent number: 5126910Abstract: A memory expansion board capable of holding up to 16 Mbytes of memory devices, using primarily 1 Mbit chips, in 2 Mbyte module increments, on a single IBM PC/AT compatible size board. The circuit board is so designed that when the memory expansion board is populated by modules and placed in a computer system it does not interfere with any of the other expansion slots within the computer system, all of the expansion slots being normally spaced apart. The memory expansion board also includes a means of protecting the memory expansion board and modules from damage due to misalignment when inserting the board and/or modules. When certain of the modules are inserted rotated 180 degrees the circuit board cannot be properly installed in the system board because of physical interference. Lastly, the memory expansion board includes a means for providing reduced length addressing memory lines to memory devices appearing on opposite sides of a circuit board.Type: GrantFiled: May 10, 1990Date of Patent: June 30, 1992Assignee: Compaq Computer CorporationInventors: James A.
