Computer Memory Socket Particulate Management System And Method

View page
US Patent:
7835155, Nov 16, 2010
Filed:
Nov 29, 2007
Appl. No.:
11/946992
Inventors:
Yefim Gelfond - Danville CA, US
Gurpreet S. Dayal - Fremont CA, US
Assignee:
Oracle America, Inc. - Redwood City CA
International Classification:
H05K 5/00
US Classification:
361759, 361801, 361802
Abstract:
A cover for memory sockets of a computer memory module includes a face panel spaced away from the memory sockets. The cover is held in place via latches associated with the memory sockets. Tabs are spaced along opposite sides of the cover to define openings for the memory sockets. Members span between opposite pairs of tabs to define air passageways underneath the cover. Each member resides between an adjacent pair of memory sockets.

Fiber Optic Radiation Transmisson System Connector For An Optical Fiber And Methods Of Usine Same

View page
US Patent:
58022295, Sep 1, 1998
Filed:
Aug 13, 1997
Appl. No.:
8/915546
Inventors:
William James Evans - San Francisco CA
Thomas Henning - San Francisco CA
Kelly Cox - Ithaca NY
Victor C. Esch - Sunnyvale CA
Yefim Gelfond - San Ramon CA
Stephanos Papademetriou - Sunnyvale CA
Daren L. Stewart - Redwood City CA
Assignee:
Indigo, Medical, Inc. - Palo Alto CA
International Classification:
G02B 600
G02B 636
US Classification:
385 88
Abstract:
A fiber optic radiation transmission system is provided in which an optical fiber and a radiation source are connected to establish optical communication therebetween. Additionally, a connecting system is provided for connecting an optical fiber and a radiation source such that optical communication is established therebetween. The systems include a connector which carries the optical fiber therein. The connector is extendable within the system toward the radiation source to bring the optical fiber into optical communication with the radiation source. More particularly, the systems are configured in such a way that when the connector is extended sufficiently within the system, it seats the optical fiber relative to the radiation source under bias, thereby establishing a reliable optical connection. Once the optical connection is thus established, the connector engages a connection port associated with the radiation source to secure the system in a fully connected configuration appropriate for use. Thus, in a method of using such a system, the user simply extends the connector until the connector engages the connection port.

Adjustable Snap-In Rail Assembly For Storage Rack

View page
US Patent:
20170181313, Jun 22, 2017
Filed:
Mar 6, 2017
Appl. No.:
15/450097
Inventors:
- Redwood City CA, US
Tina Vazirizad - Santa Clara CA, US
Yefim Gelfond - Danville CA, US
International Classification:
H05K 7/14
H05K 7/18
A47B 96/14
Abstract:
A rail assembly for a storage rack that includes, in one aspect, a first rail member, a second rail member, and a nut assembly slidably mounted to the second rail member. The first rail member may include a first mounting aperture extending through a body of the first rail member and the second rail member may include a first mounting slot extending through a body of the second rail member for a predefined dimension along a longitudinal axis. The sliding nut assembly may be slidably mounted adjacent the first mounting slot to a longitudinal position aligned with the first mounting aperture such that a fastener may be received through the first mounting aperture and first mounting slot and threaded into the first nut assembly to lock the first and second rack members against relative movement and fix the rail assembly to the front and rear pillars.
