Abstract: Orthogonal sequences can be developed and used for use training and synchronizing in CDMA and TDMA systems. In particular, once a sequence is developed that has the length of the product of the channel length and the number of transmit antennas, the sequence is offset by a different amount for each transmit antenna. For example, each sequence could be offset by a multiple of the channel length for each transmit antenna, where the multiple ranges from 0 to N-1, where N is the number of transmit antennas. Furthermore, by not using exactly the same amount of offset shifting for each transmit antenna, e.g., not having each signal offset by the channel length, but keeping the overall total shifting the same, e.g., the average of each shift is the channel length, it is possible to determine at a receiver from which transmit antenna a particular signal originated.

Title: Method and apparatus for transmitting data packets
Inventor: HAKENBERG ROLF
IPC: H04L1/00
Filed: 2001-07-17
Granted: 2007-01-23
Abstract: The invention relates to a method and apparatus for transmitting data packets over a channel wherein the data packets have compressed headers. After compressing a header using a context, a number of consecutive update packets are transmitted, each containing data indicating said context. According to the invention, the channel quality is determined and the number of update packets is set accordingly. The channel quality may be determined by measuring the block error rate or the signal-to- noise ratio. Alternatively, the channel quality may be estimated by evaluating whether a NACK message has been received. The total number of update and non- update packets transmitted during a context update phase may be set according to the Round Trip Time. The number of non-update packets may further be determined based on codec properties. The invention may advantageously be used over unreliable, e.g. wireless, channels.

Title: Motor drive apparatus
Inventor: KAWANO ATSUSHI
IPC: E05F15/16
Filed: 1999-11-30
Granted: 2004-04-13
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.
