Appl. No.:

11/294750

Inventors:

Maciek Kozyrczak - Bothell WA, US
Cheng C. Chen - Bellevue WA, US
Basem Nayfeh - Mercer Island WA, US

Assignee:

AudienceScience Inc. - Bellevue WA

International Classification:

G06F 17/30

US Classification:

707 6, 707102

Abstract:

A facility for identifying users that have an interest in a selected subject is described. For each of a number of actual users, the facility establishes a user behavior record describing the behavior of the actual user. The facility also establishes a user behavior record describing behavior of a virtual user. The behavior described by the user behavior record for the virtual user is made up of actions each tending to indicate an interest in the selected subject. The facility identifies a proper subset of the actual users whose user behavior records are most similar to the user behavior record of the virtual user as interested in the selected subject.

International Classification:

G02F 1/1335

US Classification:

349 98, 349 96

Abstract:

One embodiment of the present invention provides a display that emits circularly-polarized light. This display includes a display mechanism that emits linearly-polarized light and a layer placed in the path of the linearly-polarized light. The layer receives the linearly-polarized light on one surface, converts the linearly-polarized light to circularly-polarized light, and then emits the circularly-polarized light from another surface. By emitting circularly-polarized light, the display reduces the perceived distortion found at some angles when the display is viewed through a linearly-polarizing filter.

US Classification:

707790

Abstract:

A facility for analyzing user behavior information is described. The facility receives a stream of user behavior information. The facility augments a representation of user behavior in accordance with the received stream of user behavior information. The representation augmented by the facility is a sparse matrix of user behavior facts. The facility analyzes the sparse matrix to obtain an analysis result for the received stream of user behavior.

International Classification:

G09G 3/36

US Classification:

345 98, 345 87

Abstract:

Systems, devices, and methods for reducing direct current bias and/or enabling a simplified manner of polarity inversion in liquid crystal display (LCD) devices are provided. In accordance with one embodiment, a device may include a processor, a memory device, and a liquid crystal display having a pixel array including rows and columns of pixels. Each pixel of the pixel array may include a pixel electrode separated from a common electrode by a dielectric passivation layer, and may include a transistor to provide a data signal when the transistor is activated. The pixel array is configured such that a neutral amount of direct current bias is generated on the passivation layer when each row of pixels is activated. The common electrodes of certain pixels may be disposed above their respective pixel electrodes, while the common electrodes of certain other pixels may be disposed below their respective pixel electrodes.

Abstract:

One embodiment may take the form of a system for reducing the appearance of optical effects in a display. The system may include an enclosure with a first surface and a second surface. Furthermore, the system may include spacers that may be deposited on the bottom face of the first surface and/or the top face of the second surface, where the first surface may be a touch panel and/or cover lens and the second surface may be a display module. The spacers may be deposited in one layer with an anti-reflection coating. The thickness of the coating may be less than the diameter of the spacers.
