Title: Spatial spreading in a multi-antenna communication system
Inventor: ZHENG LIZHONG
IPC: H04L1/06
Filed: 2004-12-15
Abstract: Spatial spreading is performed in a multi-antenna system to randomize an "effective" channel observed by a receiving entity for each transmitted data symbol block. For a MIMO system, at a transmitting entity, data is processed (e.g., encoded, interleaved, and modulated) to obtain ND data symbol blocks to be transmitted in NM transmission spans, where ND >= 1 and NM> 1. The ND  blocks are partitioned into NM data symbol subblocks, one subblock for each transmission span. A steering matrix is selected (e.g., in a deterministic or pseudo-random manner from among a set of L steering matrices, where L > 1) for each subblock. Each data symbol subblock is spatially processed with the steering matrix selected for that subblock to obtain transmit symbols, which are further processed and transmitted via NT transmit antennas in one transmission span. The ND data symbol blocks are thus spatially processed with NM steering matrices and observe an ensemble of channels.

Patent CA-2573095-A1 (CA)
Inventor: COSTLOW KIMBERLY
IPC: G05B23/02
Filed: 2007-01-08
Abstract: The present invention relates generally to process control systems and devices and, more particularly, to an apparatus for and a method of implementing redundant controller synchronization for bump-less failover during normal and mismatch conditions at the redundant controllers. The redundant controllers are configured to transmit state information of the process control areas of the primary controller to the backup controller that is necessary for synchronizing the redundant controllers but is not typicall y transmitted to other devices during the performance of process control functions. Synchronization messages are transmitted from the primary controller to the backup controlle r each time one of the control areas executes to perform process control functions. In other aspects, the redundant controllers are configured to determine state information at the backup controller from other process control network information during a failover of the primary controller where a mismatch condition exists between the control areas of the two controllers during the downloading of reconfigurations, and to initialize the backup controller at startup when the mismatch condition exists.

Inventor: MORTEN JOHN EDWARD
IPC: B60P1/58
Filed: 2005-09-02
Abstract: A vehicle or trailer for transporting a load of, for example, fluent bulk material. The vehicle or trailer comprising a chassis (28) and a container mounted on said chassis (28). Said container comprises a base, a plurality of load retaining walls defining a volume for receipt of said load and a discharge opening. The container is mounted to the chassis by at least one connector (34, 35) that permits reciprocal translational movement of the container relative to the chassis (28) whilst mounted thereon between first and second positions so as to agitate the load and encourage it to flow out of the discharge opening. The at least one connector is arranged to permit translational movement of the container from the first position to the second position more slowly than from the second position to the first position.  Provision of such an arrangement in which the load is discharged by reciprocal translational movement of the container relative to the chassis obviates or at least reduces the need to tip the container to discharge the load. Thus the risk of the container rolling over whilst the load is discharged is greatly reduced.
