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.

US Patent:

Filed:

May 25, 2007

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.

Filed:

Jun 26, 2006

Appl. No.:

11/476305

Inventors:

Bernardo Huberman - Palo Alto CA, US
Li Zhang - Sunnyvale CA, US
Fang Wu - Palo Alto CA, US

Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

G06F 17/00
G06G 7/00
G06Q 30/00
G06Q 10/00

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.

US Patent:

7754433, Jul 13, 2010

Filed:

Dec 2, 2002

Appl. No.:

10/309421

Inventors:

John Babcook - Vancouver, CA
Xiao-Chi Jia - San Mateo CA, US
Jaspal Singh Kang - Surrey, CA
Li Zhang - Fremont CA, US

Assignee:

Amgen Fremont Inc. - Fremont CA

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.

Appl. No.:

11/831841

Yong Zhao - Beijing, CN

Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

G06F 7/04
G06F 17/21

US Classification:

707729, 707730, 707750, 707803, 707804

Abstract:

The relevance of documents is automatically determined based upon a weighted tree. Terms considered to be relevant are assigned to the leaf nodes of a tree data structure. A location can also be specified in a leaf node, indicating where in a document the term must appear to be considered relevant. Internal nodes of the tree are assigned operators (e. g. , add, maximum or minimum). The connections between nodes are assigned weights. A relevance value for a given document is calculated as a function of occurrence in the document of terms assigned to leaves, operators assigned to internal nodes, and weights assigned to the associated node connections. Weighted trees can be used to process search queries. Documents with high relevance scores calculated against the tree can be returned to a user as the results to a query.

G06F 9/40

US Classification:

705 5, 340 46, 712217

Abstract:

Provided are techniques for allowing consumers to reserve a resource, in which potential consumers have a choice among a number of different reservation contracts for reserving a resource to be provided at a future time. Each reservation contract allows a corresponding contracting customer to elect whether to receive the resource and requires the contracting customer to make a first payment in aggregate if the resource ultimately is elected and to make a second payment in aggregate if the resource ultimately is not elected, with the first payment being higher than the second payment, and with both being nonzero.

Appl. No.:

12/263414

Inventors:

Li Zhang - Sunnyvale CA, US

Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

G06F 7/00

US Classification:

707705, 707748, 707715, 709204, 715789

Abstract:

Described are various embodiments which enable organizations to track and use knowledge and expertise of their associated individuals. An organization can use exemplary embodiments to automatically summarize the expertise of each individual from documents available from internal or external web sites. For example, a web crawler crawls a computer network to identify documents that name an individual. Summaries of the documents are generated based on articles in an encyclopedia, and a profile is built of the individual using the summaries. These summaries are used for automatically searching and automatically discovering individuals having particular knowledge or expertise on certain topics and subjects.
