Patent number: 5793998Abstract: A computer system includes a housing, a motherboard, a first module and a second module. An electrical connector on the motherboard is joined to and in electrical communication with an electrical connector on one of two opposing surfaces of the first module, and an electrical connector on the second module is joined to and in electrical communication with another electrical connector on the other of the opposing surfaces of the first module. An electrically conductive path connects the two electrical connectors on the opposing surfaces of the first module. The motherboard transmits electrical signals corresponding to a module identifier to the first module through the motherboard's joined electrical connector. An electrical device on the first module in the electrically conductive path modifies the electrical signals so that they correspond to a second module identifier.Type: GrantFiled: April 17, 1996Date of Patent: August 11, 1998Assignee: Digital Equipment CorporationInventors: Jeffrey P. Copeland, Jonathan C. Crowell

Patent number: 5783771Abstract: The invention relates to an enclosure for computers that is formed by slidably joining together two chassis portions. A groove formed in a wall of one chassis portion mates with a tongue formed in a wall of the other chassis portion. The tongue enters one end of the groove and slides throughout the groove's length until the two chassis portions become fully joined and form a completed enclosure. The combination of the tongue and groove forms a slidable tongue and groove joint. When both chassis portions are made of electrically conductive material, the tongue and groove joint effectively inhibits the passage of electromagnetic radiation through the seam that forms at the juncture of the two chassis portions.Type: GrantFiled: October 6, 1995Date of Patent: July 21, 1998Assignee: Digital Equipment CorporationInventors: Jeffrey P. Copeland, Dennis C. Robinson

Patent number: 5726864Abstract: This invention packages option devices, such as floppy drives and hard disk drives, within an enclosure, thereby providing EMI/RFI shielding, promoting unimpeded option device electronic signaling, and reducing wasted space within an enclosure, such that small enclosures may encase the components. This invention includes a cage, for holding option devices, that is groundingly mounted in spaced relation to the major surface of a logic board, and an option device bracket that is slideably mounted within the cage. Each of the option device brackets contains one option device.Type: GrantFiled: August 24, 1995Date of Patent: March 10, 1998Assignee: Digital Equipment CorporationInventors: Jeffrey P. Copeland, Dennis Robinson

Patent number: 5717575Abstract: This invention is a system for self guiding interengagement of a securement member within a mating member having a slot for holding and securing two surface areas. The securement member is attached to one surface area and the mating member is attached to the other surface area. The securement member has a shape and the mating member has a tongue with a guiding surface, thereby promoting self guiding interengagement of the securement member within the slot of the mating member. The system is convenient for inserting a board within the obstructed view of a receptacle, such as a computer enclosure.Type: GrantFiled: August 9, 1995Date of Patent: February 10, 1998Assignee: Digital Equipment CorporationInventors: Jeffrey P. Copeland, Dennis Robinson

Patent number: 5294994Abstract: An computer assembly having an integral video display and processor subsystem in a single enclosure is described. The assembly contains an electrically conductive safety wall inside the enclosure which separates the interior of the enclosure into a high-voltage region where the video display components are mounted, and a low-voltage region where the processor subsystem is mounted. The enclosure has a removable rear cover which allows access to the processor subsystem for upgrading memory. An electrically conductive liner is attached to the rear cover for EMI shielding of the low-voltage region.Type: GrantFiled: April 6, 1992Date of Patent: March 15, 1994Assignee: Digital Equipment CorporationInventors: Dennis C. Robinson, Jeffrey P. Copeland, Ricardo L. Fernandez, Steve D. Venditti, Daniel J. J. Velasco

Patent number: 5227582Abstract: The disclosed invention relates to a video display system having a device for shielding electromagnetic radiation emitted from electrical wires which connect a video amplifier to a cathode ray tube. The device uses inexpensive unshielded wires which are recessed within a conductive shielding enclosure. The wires are connected to the cathode ray tube by a socket which is positioned at an access opening in the shielding enclosure. The invention further relates to a device for mounting a shielding enclosure to a base using tabs on the enclosure which are captured in an interference fit between the surface of the base and brackets coupled to the base.Type: GrantFiled: April 6, 1992Date of Patent: July 13, 1993Assignee: Digital Equipment CorporationInventors: Daniel J. J. Velasco, Dennis C. Robinson, Jeffrey P. Copeland, Ricardo L. Fernandez
