Abstract: Systems and methods utilize a display to provide universal remote control functionality. A menu of options appears on a display of a display device. A user can navigate the various options to control devices that are separate from the display device. The menu may be dynamically configured according to the context in which the display device is being used. The menu may be activated using a remote control device or other device and the menu may include options for controlling one or more devices that are absent from the remote control device.

Abstract: Techniques for content navigation utilize proximity sensing so that user interaction with a graphical user interface is based at least in part on both contact with a surface and contactless interaction with the surface. A representation of an object detected as being proximate to and/or in contact with a surface appears on a display, which may be separate from the surface. The representation may appear at a location of the display that is determined according to a mapping of surface locations to display locations. The representation is updated based at least in part on movement of the object relative to the surface and one or more distances of the object from the surface.

Abstract: Systems and methods enhance content from one source with content obtained from another source. Information about content, such as content that is or will be experienced by a user, is used to identify the content from another source. The content from the other source may be content of a different type than the content being enhanced. The content from the two (or more) sources are combined and provided simultaneously. The combined content may be provided using a set of one or more electronic devices.

Abstract: A method and apparatus for constructing an inexpensive camera with vignetting correction in the camera electronic hardware. The hardware is programmable through the use of a register storing a constant value corresponding to the amount of vignetting of a particular lens used in the camera. The register value is provided to a correction circuit which implements an algorithm that corrects for the amount of vignetting of pixels depending upon the pixel position.

Abstract: The disclosure includes a video (including audio) processing system for transmission of a video frame across a network. The system includes a video input mechanism, a motion detection mechanism, and a web cam mechanism. The video input mechanism is configured to receive a first video frame and a second video frame. The motion detection mechanism is configured to compare the first video frame with the second video frame. It is also configured to generate a motion-detected signal if the comparison of the frames deviates from a threshold value. The web cam mechanism is configured to transmit the second video frame if it received the motion detection signal from the motion detection mechanism. The disclosure also includes a method for processing a selected video frame for transmission across a network.

Abstract: A method and apparatus for detecting motion in digitized images involves the use of discrete cosine transforms. Video images are reduced in size to reduce the number of DCT blocks used in the analysis. Similarly, quantization of only portions of the DCT blocks are needed to detect motion between successive video images.

Abstract: An encoder having a movable element with a first polarized filter coupled to the movable element. A second polarized filter is either stationary, or moves differently from the first polarized filter. A photo-emitter and photodetector are arranged on opposite sides of the two polarized filters. Thus, when the polarized filters are aligned in phase, a maximum amount of light will penetrate to the photodetector. However, as they become out of phase due to movement of one of the filters, the amount of light will decrease, as a function of the amount of movement.

Abstract: A cordless mouse with an upper and lower housing. The lower housing includes a hole for receiving a ball which extends through the hole in the bottom of the mouse. The upper housing is uniquely provided with a cavity for receiving a battery, with a portion of the cavity extending over the ball.

Abstract: A method and apparatus for eliminating in at least one light emitter and light detector in a mouse design. This is done by using two conical shaped encoder wheels positioned so that they are almost touching each other. A single light emitter then is used to shine light at the junction, so that it passes through both cones. On the opposite side is a single chip, with two photodetectors integrated on each side. The chip is positioned so that light passing through the first conical encoder impinges on the first photodetector, while light passing through the second conical encoder impinges on the second photodetector. Thus, the two photodetectors can be integrated on a single chip, saving a separate photodetector chip. In addition, only a single LED is required.

Abstract: An optical detection system and method detects movement of an optical pointing device in a data processing environment. The system works with any surface than can diffusely scatter a collimated beam from a coherent light source. Specifically, the system comprises a coherent light source and an optical sensing assembly. The optical sensing assembly comprises a plurality of photosensor arrays and a plurality of optical elements. Each photosensor array includes pixels of a particular size and shape. Each optical element has an artificially limited aperture and is associated, through optical matching, with a respective photosensor array. The coherent light source generates a collimated beam that is diffusely reflected off of the surface. The optical sensing assembly receives the diffusely reflected, or scattered, collimated beam and passes it through the artificially limited apertures of the optical elements to the associated corresponding photosensor array.

On the other side of the circuit board is a flexible metal sheet which is contacted by the pins, and moved away from the coils in a direction in which the micro-stick is tilted. This increased separation of the metal sheet from the coils can then be detected.
