    摘要： A method and apparatus for combining video frame sequences with a video display of an interactive program guide (IPG). The apparatus comprises a plurality of compositors that combine background information, video frame sequences and program guide graphics into a single video frame sequence. The sequence is then digitally encoded to form an MPEG-like bitstream. The same background information and informational video is composited with a different program guide graphic to form another video sequence that is also encoded. A plurality of such sequences are produced with each sequence having a different program guide graphic. Each sequence is encoded and then multiplexed into a transport stream such that all the encoded sequences are transmitted to a subscriber's terminal using a single transport stream. As such, the subscriber can transition from one program guide to the next without interruption of the background or video display as the program guide graphic is changed.

    摘要： The quality of ping-based ultrasound imaging is dependent on the accuracy of information describing the precise acoustic position of transmitting and receiving transducer elements. Improving the quality of transducer element position data can substantially improve the quality of ping-based ultrasound images, particularly those obtained using a multiple aperture ultrasound imaging probe, i.e., a probe with a total aperture greater than any anticipated maximum coherent aperture width. Various systems and methods for calibrating element position data for a probe are described.

    摘要： Tape guides of a magnetic tape transport machine are controlled during movement by sensing the position of the member as it moves along a defined path in varying velocity corresponding to the position. The member is initially accelerated at a selected rate to a maximum velocity which is then maintained until a distance close to the end position is reached. Velocity is then reduced at a selected rate until another position closer to the end position is reached. At this position a final velocity is maintained until the end is reached. A determination is made of how closely the second distance from the end coincided with reaching the final velocity. The length of the first distance from the end position is adjusted to reduce the difference between the coincidence of reaching the second distance and the final velocity. Further, the sensed final position of the member is retained as the target final position for the subsequent operation.
