Title: Method for creating a digital data stream
Inventor: PORTER MARK A
IPC: H04N19/61
Filed: 1996-07-12
Abstract: A method and apparatus for use in a digital video delivery system is provided. A digital representation of an audio-visual work, such as an MPEG file, is parsed to produce a tag file. The tag file includes information about each of the frames in the audio-visual work. During the performance of the audio-visual work, data from the digital representation is sent from a video pump to a decoder. Seek operations are performed by causing the video pump to stop transmitting data from the current position in the digital representation, and to start transmitting data from a new position in the digital representation. The information in the tag file is inspected to determine the new position from which to start transmitting data. To ensure that the data stream transmitted by the video pump maintains compliance with the applicable video format, prefix data that includes appropriate header information is transmitted by said video pump prior to transmitting data from the new position. Fast and slow forward and rewind operations are performed by selecting video frames based on the information contained in the tag file and the desired presentation rate, and generating a data stream containing data that represents the selected video frames. A video editor is provided for generating a new video file from pre-existing video files. The video editor selects frames from the pre-existing video files based on editing commands and the information contained in the tag files of the pre-existing video files. A presentation rate, start position, end position, and source file may be separately specified for each sequence to be created by the video editor.

Title: Correction of amplitude and phase imbalance in psk receivers
Inventor: OZLUTURK FATIH M
IPC: H04L27/18
Filed: 1999-12-07
Abstract: The present invention balances the amplitude and phase of a received QPSK  signal that may have been corrupted during transmission. The system determines the amplitude of the I and Q symbols of a received signal, compares them, and applies a correction to one or both channels to correct for amplitude imbalance. For phase imbalance, the system calculates the cross-correlation of the I and Q symbols which should average to zero. A correction factor is derived from the cross-correlation and applied to both channels, returning the phase cross-correlation to zero. The output from the system is a signal corrected in both amplitude and phase.

Patent CA-2354800-A1 (CA)
Inventor: SAKUMA YOICHI
IPC: E05F15/16
Filed: 1999-11-30
Abstract: An apparatus for driving a motor that opens and closes the window of vehicle, for example, is so adapted that when the vehicle becomes submersed in the sea, a lake or a river, etc., the window is prevented from being closed owing to malfunctioning of a relay caused when a leakage current flows into an operating switch for opening and closing the window. When submersion is sensed and it is sensed that the motor is being rotated by a malfunction in a direction that closes the window, a relay for rotating the motor in the forward direction is actuated. This prevents the occurrence of a situation in which the motor is caused to rotate (especially in the direction that closes the window) regardless of the fact that the operating switch has not been operated.
