H01J 162

US Classification:

430 25, 313466, 313495

Abstract:

A multi-level matrix structure for frictionally retaining a support structure within a flat panel display device. In one embodiment, the present invention is comprised of a multi-level matrix structure. The multi-level matrix structure of the present embodiment is comprised of a first multi-layered structure disposed on an inner surface of a faceplate of a flat panel display device. The multi-level matrix structure of the present embodiment is further comprised of a plurality of substantially parallel spaced apart ridges. In this embodiment, the plurality of substantially parallel spaced apart ridges overlie the first multi-layered structure. Additionally, in this embodiment, the plurality of substantially parallel spaced apart ridges include contact portions for frictionally retaining a support structure in a first direction at a desired location within the flat panel display device.

Abstract:

A multi-level matrix structure for retaining a support structure within a flat panel display device. In one embodiment, the multi-level matrix structure is comprised of a first parallel ridges. The multi-level matrix structure further includes a second parallel ridges. The second parallel ridges are oriented substantially orthogonally with respect to the first parallel ridges. In this embodiment, the second parallel ridges have a height which is greater than the height of the first parallel ridges. Furthermore, in this embodiment, the second plurality of parallel spaced apart ridges include contact portions for retaining a support structure at a desired location within a flat panel display device. Hence, when a support structure is inserted between at least two of the contact portions of the multi-level support structure, the support structure is retained in place, at a desired location within the flat panel display device, by the contact portions.

Inventors:

David Chang - Albany CA 94706

International Classification:

A61B 1700

US Classification:

600219, 600213

Abstract:

A surgical retractor comprises a pair of arms having a common pivotal connection and a pair of retractor blades, each blade detachably connected to an arm by a rotating knee joint which allows the retractor blade to rotate about an axis parallel to the arm and also about an axis perpendicular to the arm. A detent locking mechanism allows any selected pair of a plurality of pairs of retractor blades to be detachably attached to the arms. The knee joint comprises an open sleeve for easy sanitizing. The arms are opened and closed using handles having a locking ratchet mechanism and pawl allowing the arms to be locked in any open position.

US Classification:

438270, 438212, 438268, 438272, 438589

Abstract:

A trench MOSFET is formed by creating a trench in a semiconductor substrate, then forming a barrier layer over a portion of the side wall of the trench. A thick insulating layer is deposited in the bottom of the trench. The barrier layer is selected such that the thick insulating layer deposits in the bottom of the trench at a faster rate than the thick insulating layer deposits on the barrier layer. Embodiments of the present invention avoid stress and reliability problems associated with thermal growth of insulating layers, and avoid problems with control of the shape and thickness of the thick insulating layer encountered when a thick insulating layer is deposited, then etched to the proper shape and thickness.

US Classification:

707721, 705 1454

Abstract:

A system to provide search query information. The system receives a request for search query information, identifies a set of search queries from a search query log that includes search queries submitted to a search service over a predetermined length of time, and provides the set of search queries. Each of the set of search queries is associated with at least a predetermined number of unique identifiers. Each of the set of search queries is matched to the request for search query information by a combination of exact matches, expanded matches, and broad matches.

Abstract:

A virtual space may be provided to users. In providing the virtual space to users, actions performed in the virtual space responsive to user input may be dynamically assigned a quality of service that is dependent on one or more of user value, past user action requests, past action requests cumulatively for all users, server health, and/or other criteria. This may facilitate an operator of the virtual space increasing overall user engagement and/or value, and/or provide other enhancements.
