  • Publication number: 20100195867
    Abstract: A method of tracking a target includes receiving an observed depth image of the target from a source and analyzing the observed depth image with a prior-trained collection of known poses to find an exemplar pose that represents an observed pose of the target. The method further includes rasterizing a model of the target into a synthesized depth image having a rasterized pose and adjusting the rasterized pose of the model into a model-fitting pose based, at least in part, on differences between the observed depth image and the synthesized depth image. Either the exemplar pose or the model-fitting pose is then selected to represent the target.

  • Patent number: 7421111
    Abstract: An interactive display system includes a pixel-based display surface and a light pen. A sequence of patterns is projected onto the display surface. The sequence of patterns has a unique sequence of light intensities for each location of the display surface. Intensities of light at an arbitrary location are sensed by the light pen while projecting the sequence of patterns. The intensifies of light are decoded to determine coordinates of the arbitrary location.

  • Patent number: 7001023
    Abstract: A system determines correspondence between locations on a display surface and pixels in an output image of a projector. The display surface can have an arbitrary shape and pose. Locations of known coordinates are identified on the display surface. Each location is optically coupled to a photo sensor by an optical fiber installed in a throughhole in the surface. Known calibration patterns are projected, while sensing directly an intensity of light at each location for each calibration pattern. The intensities are used to determine correspondences between the locations and pixels in an output image of the projector so that projected images can be warped to conform to the display surface.

  • Patent number: 6662262
    Abstract: A simultaneous operation flash memory capable of providing double protection to An OTP sector. The preferred simultaneous operation flash memory comprises an OTP write-protect CAM, which is in a programmed state if the OTP sector is write-protected. In addition, the preferred simultaneous flash memory further includes an OTP sector lock CAM that is electrically connected with the OTP write-protect CAM. The OTP sector lock CAM is used to lock the OTP write-protect CAM in the programmed state, which, in turn, will designate the OTP sector as read only.

  • Patent number: 6178129
    Abstract: A flash memory device (100) provides for simultaneous read and write operations in two banks (194, 196) of flash memory cells. A plurality of output circuits (182) switch large amounts of current during reading of stored data. To reduce noise in read circuitry (174) and write circuitry (142), a separate power supply bus (204) and ground bus (208) is provided for the output circuits. The power supply bus is independent of the power supply bus which serves the internal circuitry, such as the read circuitry and the write circuitry.
