Appl. No.:

09/474361

Inventors:

Mark E. Holzbach - Austin TX
David T. Chen - West Somerville MA

Assignee:

Zebra Imaging, Inc. - Pflugerville TX

International Classification:

G03H 126

US Classification:

359 23, 345427, 345619, 345620, 345621, 345622, 345623, 345624, 348 40, 348 42

Abstract:

A method of rendering image data for full parallax autostereoscopic displays. The method is based on a double frustrum camera technique, where two cameras provide image data from opposing sides of an image plane. The near clipping plane is located on the image plane. The distance between the near clipping plane and the eyepoint of the camera frustra is adjusted to minimize or avoid clipping.

International Classification:

H03K 17/16
G06F 17/50

US Classification:

326 30, 36518911

Abstract:

A memory interface device, system, method, and design structure for controlling for variable impedance and voltage in a memory system are provided. The memory interface device includes a calibration cell configurable to adjust an output impedance relative to an external reference resistor, and driver circuitry including multiple positive drive circuits and multiple negative drive circuits coupled to a driver output in a memory system. The memory interface device further includes impedance control logic to adjust the output impedance of the calibration cell and selectively enable the positive and negative drive circuits as a function of a drive voltage and a target impedance.

Stephen Dusse - Woodside CA, US

International Classification:

H04M003/00

US Classification:

455/419000, 455/466000, 455/426000

Abstract:

A method and apparatus for provisioning a mobile station over a wireless network are described. The mobile station contains a browser to allow navigation of hypermedia content. The browser sends a request for provisioning content to a remote provisioning server via the wireless network. The request includes a network resource locator. In response, the provisioning server sends a markup language document via a wireless network to the mobile station, containing a reference to provisioning content. The browser retrieves the provisioning content based on the reference and stores the provisioning content in the mobile station. The provisioning content is used in the mobile station to enhance a capability of the mobile station.

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G06F 17/28

US Classification:

704 2

Abstract:

The subject disclosure generally describes a technology by which text and/or speech descriptions are collected by showing a stimulus such as video clips to contributors (e.g., of a crowd-sourcing service). The descriptions, which are in the language of each contributor's choice, are of the same stimulus and thus associated with one another. While each contributor may be monolingual, the technique allows for the collection of approximately bilingual data, since more than one language may be represented among the different contributors. The descriptions may be used as translation data for training a machine translation engine, and as paraphrase data (grouped by the same language) for training a machine paraphrasing system. Also described is evaluating the quality of a machine paraphrasing system via a distinctiveness metric.
