Title: Data transmission with spatial spreading in a mimo communication system
Inventor: WALLACE MARK S
IPC: H04L1/06
Filed: 2005-01-11
Abstract: For data transmission with spatial spreading, a transmitting entity (1) encodes and modulates each data packet to obtain a corresponding data symbol block, (2) multiplexes data symbol blocks onto Ns data symbol streams for transmission on Ns transmission channels of a MIMO channel, (3) spatially spreads the Ns data symbol streams with steering matrices, and (4) spatially processes Ns spread symbol streams for full-CSI transmission on Ns eigenmodes or partial-CSI transmission on Ns spatial channels of the MIMO channel. A  receiving entity (1) obtains NR received symbol streams via NR receive antennas, (2) performs receiver spatial processing for full-CSI or partial-CSI  transmission to obtain Ns detected symbol streams, (3) spatially despreads the Ns detected symbol streams with the same steering matrices used by the transmitting entity to obtain Ns recovered symbol streams, and (4) demodulates and decodes each recovered symbol block to obtain a corresponding decoded data packet.

Title: Load interrupter upon lowering of frequency
Inventor: YASUDA TADAAKI
IPC: H02J3/24
Filed: 2004-04-09
Abstract: A load interrupter for operating a power system stably by returning the system frequency of a power system to a specified range upon lowering thereof. A  frequency lowering level judging section judges the lowering level of system frequency when it lowers due to deficiency of generated power in the power system.

Abstract: In one aspect, the present invention provides a genetically modified cell or non-human organism comprising such cells comprising modified genetic material which when expressed produces a polypeptide co-expressed with a reporter molecule and wherein the polypeptide is associated with terminal differentiation of a haematopoietic cell. Preferably, the genetic material gene is a Blimp allele or a part, fragment or functional form thereof.  Furthermore, the identification of the reporter molecule in B-cell lineage cells indicates that such cells are committed to differentiate or have differentiated into ASC. Alternatively, reporter molecule activity in cells of a T cell lineage indicates that these cells are activated. Thus, as described herein, the presence of Blimp in a lymphocyte indicates that the cell is terminally differentiated or is committed to terminal differentiation.  Exemplary T-cells include CD4+ T-cells and CD8+ T-cells and exemplary B-cells are ASC.
