  • Patent number: 6060995
    Abstract: A novel paging technology allows a group of subscribers to share and take advantage of nightlife information. A service provider collects and stores such information. The information is then compared to a profile for each subscriber detailing what type of information that subscriber is interested in receiving. Information may further be screened for that relevant to an particular area where the subscriber's pager is determined to be. Information matching the interest profile and/or location of each subscriber is then transmitted to that subscriber's pager. Each subscriber's pager may include an input device, such as a virtual keyboard, so that each subscriber can submit information to the system to be shared with other subscribers.

  • Patent number: 6058142
    Abstract: An image processing apparatus, wherein image data is stored in a current block memory and image data of a search range of a reference picture is stored in a search window memory. Using a gray code, the register file of the search window memory is read, candidate blocks are successively extracted, and the image data is successively input to processor elements. The data stored in the current block memory is input to a register and input through a barrel shifter to the processor elements. The processor elements find the differences of the current block and candidate blocks, find the cumulative values, compare the cumulative values of differences at a comparison unit, extract the candidate block giving the smallest value, and detect the motion vector based on the candidate block.
