  • Patent number: 7797018
    Abstract: A method and apparatus for selecting one of a plurality of multi-band access points (APs) to associate with a multi-band wireless transmit/receive unit (WTRU) are disclosed. The multi-band APs broadcast frequency band information regarding multiple frequency bands on which the multi-band AP is configured to operate. The multi-band WTRU selects a particular multi-band AP to associate with and a frequency band to use to communicate with the selected multi-band AP based on the frequency band information. If the multi-band WTRU receives frequency band information from the selected multi-band AP which indicates that a characteristic, (e.g., throughput, path loss, load, capacity, backhaul), of the selected frequency band is unacceptable, the multi-band WTRU determines whether to disassociate with the selected multi-band AP or to continue to associate with the selected multi-band AP via a different frequency band.

  • Patent number: 7792338
    Abstract: A method and apparatus for creating a magnified composite image of a microscope specimen comprises making error corrections for imprecise movements of the specimen relative to an objective lens when capturing data for first and second images. A correction offset is computed based on a comparison of data for overlapped portions of the first and second images and then the specimen is moved through a distance modified by the correction offset for capture of a subsequent tiled image. Image center portions are retained as the data structure tile. The area about the center portion is used to align images and to compensate for stage inaccuracies and to provide a feedback signal for a drive system. Differences in X, Y coordinates for macro and micro view images may be used as navigation offsets to view a selected point for the micro image marked on the macro image.
