US Patent:

Filed:

Dec 12, 2003

Appl. No.:

10/734713

Inventors:

Raymond G. Beausoleil - Redmond WA, US
Tad Hogg - Mountain View CA, US

International Classification:

G06E 1/00

US Classification:

706 15, 257 9, 977755, 977762

Abstract:

A quantum approach to the economically significant n-player public goods or similar n-player game requires only two-particle entanglement and is thus much easier to implement than games requiring n-particle entanglements. Two-particle entanglements are sufficient to give near optimal expected payoff when players use a simple mixed strategy for which no player can benefit by making different choices. This mechanism can also address some heterogeneous preferences among the players. Quantum games in accordance with the invention can be simulated on classical computers without requiring impractical amounts of processing power for large numbers of players.

International Classification:

F21V 29/00

US Classification:

362294, 36224902, 362373

Abstract:

A light emitting diode (LED) apparatus for mounting to a heat sink having a front surface with an opening therein is disclosed. The apparatus includes a sub-mount, at least one LED die mounted on the sub-mount, and a thermally conductive slug having first and second areas. The first area is thermally coupled to the sub-mount and the second area has a post protruding outwardly therefrom. The post is operably configured to be received in the opening in the heat sink and to secure the LED apparatus to the heat sink such that the second area is thermally coupled to the front surface of the heat sink. Other embodiments for mounting an LED apparatus utilizing adhesive thermally conductive material, spring clips, insertion snaps, or welding are also disclosed.

Appl. No.:

11/754210

Inventors:

Li Zhang - San Jose CA, US
Richard S. Kern - Los Altos CA, US
Jeffrey D. Kmetec - Palo Alto CA, US

Assignee:

Philips Lumileds Lighting Company LLC - San Jose CA

International Classification:

H01L 33/00

US Classification:

257 99

Abstract:

An illumination device includes a light source, such as one or more light emitting diodes and a wavelength converting element that is mounted on an opaque support structure. The support structure includes an aperture with which the wavelength converting element is aligned so that the converted light is emitted through the aperture. The wavelength converting element may be a rigid structure, such as a luminescent ceramic and the aperture may be a hole through the support structure. The support structure may hold the wavelength converting element so that it is physically separated from the light source, or alternatively, the support structure may place the wavelength converting element in physical contact with the light source.

US Classification:

705400, 705 11, 705 5, 705 6

Abstract:

Provided are systems, methods and techniques for establishing a pricing structure for reserving a resource. An option is selected from among a plurality of available options with respect to delivery of a resource at a specified future time, and then the selected option is presented to a customer. Each of the plurality of options includes: (i) a reservation price at which the customer may reserve the resource, and (ii) a compensation amount that must be paid if the resource is not delivered at the specified future time. The specified future time may be either a point in time or an interval of time.

International Classification:

G06K 9/34

US Classification:

382173

Abstract:

Method and apparatus for face alignment by building a hierarchical classifier network. The hierarchical classifier network connects the tasks of face detection and face alignment into a smooth coarse-to-fine procedure. Texture classifiers are trained to recognize feature texture at different scales for different resolution layers. A multi-layer structure is employed to organize the texture classifiers, which begins with one classifier at the first layer and gradually refines the localization of feature points using additional texture classifiers in subsequent layers.

US Classification:

382128, 378 21

Abstract:

A method for detecting solid components in ground glass nodules (GGNs) in medical images, includes: performing an intensity-based segmentation on a segmented GGN to identify a high intensity region; and performing a shape analysis to determine whether the high intensity region is a solid component or a vessel, wherein the shape analysis comprises: computing a compactness of the high intensity region; and determining whether the high intensity region is a solid component or a vessel by using an area, a maximum distance on a distance transform map and the compactness of the region; or determining whether the high intensity region is a solid component or a vessel by scaling and normalizing the region and computing a compactness for the scaled and normalized region.

International Classification:

G01N 33/53

US Classification:

435 71, 435 6, 435 72

Abstract:

Methods are disclosed for determining the relative binding affinities of molecules for their binding partner. One type of molecule is an antibody, which has an antigen binding partner. Antibodies are tested for binding against limited dilutions of antigen. Antibodies that bind to the most dilute antigen concentrations are determined to have a higher relative binding affinity for the antigen than antibodies that only bind to more concentrated antigen preparations.
