Filed:

Aug 8, 2003

Appl. No.:

10/637333

Inventors:

Phong Hoang Ho - Cary NC, US
Sean P. Ryan - Wake Forest NC, US

Assignee:

Cisco Technologies, Inc. - San Jose CA

International Classification:

H05K 9/00

US Classification:

174354, 174368, 174372

Abstract:

The disclosed device is directed towards an electromagnetic compatibility clip comprising a body having a first side and a second side opposite the first side. The first side is configured to contact a top surface of a chassis separator and a bottom surface of the chassis separator. The second side of the body is configured to contact an upper module mounted on the upper surface of the chassis separator. The second side of the body is configured to contact a lower module mounted on the lower surface of the chassis separator. The body is configured to maintain electrical contact between the chassis separator, the upper module and the lower module. A locking portion is defined in the body. The locking portion is configured to interlock with the chassis separator. A compression force control element is defined in the body. At least one spring contact is defined in the body.

International Classification:

H05K 1/14

US Classification:

361749, 174254

Abstract:

Flexible paddle cards for installation on a motherboard of a computing system are disclosed that are oriented parallel with the motherboard when installed in the computing system and include: a printed circuit board; and three card connectors that correspond to three motherboard connectors mounted on the motherboard, two of the card connectors mounted on a first rigid region of the printed circuit board, the remaining third card connector mounted on a second rigid region of the printed circuit board, and the first rigid region and the second rigid region separated by a flexible region of the printed circuit board, the flexible region having a width that allows the printed circuit board to flex when the card connectors mate with the motherboard connectors.

Appl. No.:

9/062431

Inventors:

Sean P. Ryan - Wake Forest NC

Assignee:

Ericsson, Inc. - Research Triangle Park NC

International Classification:

H01M 1046
H01M 1044

US Classification:

320106

Abstract:

A loose type battery cell detection method and apparatus controls a battery charging circuit so as to disable recharging when loose battery cells are detected. A battery contact is disposed adjacent to a battery power source. If the battery power source is loose battery cells, the battery contact operatively engages the loose battery cells such that an electrical path is created from one loose battery cell to another via the battery contact. If the battery power source is a rechargeable battery pack, no electrical path between the battery power source and the battery contact is created. A battery detection circuit monitors the battery contact for an electrical signal, such as a voltage or current level above zero. While the electrical signal is detected, the battery detection circuit directly or indirectly causes the battery recharge function of the battery charging circuit of the recharging device to be disabled.

Sean Patrick Ryan - Wake Forest NC

Assignee:

Ericsson Inc. - Research Triangle Park NC

International Classification:

G02F 11335

US Classification:

359599

Abstract:

A applied diffusor structure for lightguides fabricated out of a flexible transparent film substrate.

Sean Ryan - Wake Forest NC

Assignee:

Ericsson Inc. - Research Triangle Park NC

International Classification:

H04B1/38

US Classification:

455550

Abstract:

A telephone is provided with a first housing and a second housing slideably secured to the first housing for movement between an open position and a closed position, said second housing projecting out from said first housing in said open position. The telephone also includes an antenna pivotably attached to said second housing. A position control mechanism is provided to pivot said antenna away from said second housing, and a guide is provided to secure said antenna against pivoting when said second housing is in said closed position.
