Patent number: 9521769Abstract: A latch apparatus is provided with a dual action mechanism that can either pivot a cam hook from a first side of the apparatus for securing a sub-chassis into a chassis of laterally extend a component lock from a second side of the apparatus for securing a component within the sub-chassis. A single rotary actuator may be rotated in a first rotational direction to pivot the cam hook to an extended position and move the component lock to a retracted position, and rotated in a second rotational direction to pivot the cam hook to a retracted position and move the component lock to an extended position. The latch apparatus may include one or more of the dual action mechanisms actuated by the single actuator.Type: GrantFiled: August 14, 2014Date of Patent: December 13, 2016Assignee: Lenovo Enterprise Solutions (Singapore) Pte. Ltd.Inventors: Steven E. Howell, Michael I. McGregor, Camillo Sassano, Jared E. Schott

Patent number: 9063705Abstract: An apparatus includes a frame forming a bay for receiving an electronic module having a blind mate connector for coupling with a chassis connector. An actuator is slidably secured to the frame and forms a push button, an intermediate actuation member, and a distal actuation member. A spring latch is biased to latch the module in place. An ejection lever is pivotally secured to one side of the bay, and has a first end aligned with the distal actuation member and a second end disposed to engage the module. Pushing the push button causes the intermediate actuation member to withdraw the spring latch from the bay and then causes the distal actuation member to pivot the ejection lever to unseat and eject the module.Type: GrantFiled: November 11, 2013Date of Patent: June 23, 2015Assignee: Lenovo Enterprise Solutions (Singapore) Pte.

Patent number: 7257043Abstract: A memory device includes isolation devices located between-memory cells. A plurality of isolation lines connects the isolation devices to a positive voltage during normal operations but still keeps the isolation devices in the off state to provide isolation between the memory cells. A current control circuit is placed between the isolation lines and a power node for reducing a current flowing between the isolation lines and the power node in case a deflect occurs at any one of isolation devices.Type: GrantFiled: February 21, 2006Date of Patent: August 14, 2007Assignee: Micron Technology, Inc.Inventors: Luan C. Tran, Stephen R. Porter, Scot M. Graham, Steven E. Howell

Patent number: 6182173Abstract: A computer has at least one adapter card slot for receiving an optional adapter card. A cover plate is rotatable hinged and has open and closed positions. In the closed position, the cover plate covers the adapter card slot and inhibits the insertion or removal of an adapter card. When the cover plate is raised into the open position, a tab on the back of the cover plate is rotated out of the slot of an optical switch, and the optical switch then signals circuitry to remove power and bus signals from the adapter card slot; thereby permitting the adapter card to be removed from or inserted into the slot without removing power to the entire computer. When the cover plate is returned to the closed position, the tab is reinserted into the slot of the optical switch, which in turn signals the circuitry to return power and bus signals to the adapter card slot.Type: GrantFiled: November 14, 1997Date of Patent: January 30, 2001Assignee: International Business Machines CorporationInventors: Cynthia M. Grosser, Susan P. Wise, Michael Sven Miller, Brian Alan Trumbo, Michael J. Huck, Steven E. Howell, Courtney Long, Andrew Stern Heinzmann, Richard P. Southers

Patent number: 5420760Abstract: This invention relates to enclosures for microcomputers, and more particularly to such an enclosure which facilitates access to and shielding of the operative components of a personal computer. The enclosure includes a chassis, a cover for cooperating with the chassis for enclosing a volume to contain operating components of the microcomputer, and interrupted wedge members for coupling the chassis and cover upon relative movement therebetween in a predetermined direction. The interrupted wedge members include a plurality of hooks on one of the chassis and cover and a plurality of pockets on the other, with the hooks and pockets being disposed along two sides of the chassis and cover for entry of hooks into cooperating pockets on movement of the cover into position for cooperation with the chassis in enclosing a volume.Type: GrantFiled: May 11, 1994Date of Patent: May 30, 1995Assignee: International Business Machines Corp.Inventors: Daniel F. Ansell, Jeffrey W. Benck, James C. Harris, Steven E. Howell, Brian A. Trumbo, Robert D. Wysong

Patent number: 4862327Abstract: In a low profile microcomputer, adapter cards are mounted horizontally in order to be able to use adapter cards designed for earlier, higher, machines. The cards are coupled to the microcomputer planar board by an extender card which extends vertically from the planar and has sockets extending horizontally when the card is in position. The adapter cards have edge connections which couple to these sockets. A removable bridge device is coupled between the top of the extender card and a vertical wall of the microcomputer to minimize horizontal movement of the extender card. For adapter cards which do not extend fully between the front and rear walls of the microcomputer, a channelled support arm, which fits over an end of a card, and is removably mounted on a vertical wall of the computer for slidable engagement with the card.Type: GrantFiled: June 9, 1988Date of Patent: August 29, 1989Assignee: International Business Machines CorporationInventors: Daniel F.

Patent number: 4561620Abstract: In a CRT display device system, an upper assembly, including the display device, is tiltable on a supporting base assembly. A gear segment at each end of the upper assembly rests on a pair of pinions on the base assembly. The radius of curvature of each gear segment is centered on a horizontal line passing across the display device and through or near the center of gravity of the upper assembly. As the upper assembly is tilted, it pivots about this line and therefore remains substantially in balance for all angles of tilt. To provide static rest pressure to prevent unwanted tilting movement and also to minimize backlash, the pinions in each pair are coupled together through an idler pinion.Type: GrantFiled: May 3, 1984Date of Patent: December 31, 1985Assignee: International Business Machines Corp.Inventors: Fred E. Goetz, Jim C. Harris, Steven E. Howell
