Patent CA-2607606-A1 (CA)
Inventor: ABRAHAM SANTOSH
IPC: H04J99/00
Filed: 2006-05-09
Abstract: Techniques for selecting rates for data transmission on eigenmodes of a MIMO  channel are described. An access point transmits an unsteered MIMO pilot via the downlink. A user terminal estimates the downlink channel quality based on the downlink unsteered MIMO pilot and transmits an unsteered MIMO pilot and feedback information via the uplink. The feedback information is indicative of the downlink channel quality. The access point estimates the uplink channel quality and obtains a channel response matrix based on the uplink unsteered MIMO pilot, decomposes the channel response matrix to obtain eigenvectors and channel gains for the eigenmodes of the downlink, and selects rates for the eigenmodes based on the estimated uplink channel quality, the channel gains for the eigenmodes, and the feedback information. The access point processes data based on the selected rates and transmits steered data and a steered MIMO  pilot on the eigenmodes with the eigenvectors.

Title: Method and system for using contactless payment cards in a transit system
Inventor: WILHELM BURT A
IPC: G06Q20/34
Filed: 2006-05-16
Abstract: An automatic fare collection solution for a transit system exploits the use of smart payment cards (e.g., MasterCard's PayPass cards) by the commercial payment card industry. The smart payment cards that are issued by commercial card issuers and banks to customers conform to a common or open industry standard such as the ISO 14443 standard for contactless payment cards. A  cardholder seeking access to transit services presents his or her smart card to an RFID-enabled card reader at a transit system entrance. The cardholder is granted quick access unless his or her smart card is list of "hot" cards (i.e., lost or stolen, expired or delinquent cards). A card transaction record is prepared and communicated from the card reader to a transit payment platform. The transit payment platform is linked by conventional payment-by-card electronic networks to card issuers and banks for authorization, clearing and settlement of the card transaction.

Inventor: REZNIK ALEXANDER
IPC: H04B1/707
Filed: 2000-02-11
Abstract: A parallel interference cancellation receiver that reduces impulse response interference using a model of the received signal similar to that used in block linear equalizers. Block linear equalizers comprise decorrelating receivers, zero-forcing receivers, minimum mean square error receivers and the like. The invention comprises an interference computation processor feedback loop for correcting the output of a direct interference canceller. The m iterative process removes interferers from the output symbols of a matched-filter. The PIC receiver uses received signal models of the various block linear equalizers that do not assume that each subchannel consists of several distinct paths. The receiver estimates the impulse response characteristic of each subchannel as a whole.

Abstract: A system and method for the percutaneous, autologous transplantation of mesenchymal stem cells and progenitor helper cells (PHC) from bone marrow to degenerated intervertebral discs or joints. This method is designed to be used by operating room staff in a clinical setting to isolate a mesenchymal stem cell population and PHC during the same surgical procedure as transplantation.  The method can be used as a two step procedure where cells are harvested, then isolated, then reimplanted at a later time. In addition, experimental techniques are described to determine which bone marrow cells should be removed via negative selection to generate a PHC population most likely to regenerate certain tissue types in-vitro as well as which combination of fibrinogen and hyaluronic acid and which degree of gel maceration provides the best matrix for in-vitro and in-vivo regeneration of joints and intervertebral discs.

Abstract: First video data is used for outputting a video signal of a main image. Second video data is used for outputting a video signal of an information incorporation mark image (4) reflecting control information contents used for controlling the operation of a controlled object external device (62). Expansion video data including the first video data and second video data is recorded in a video recording medium (61M). An external device controller (60) of the present invention separates the expansion video signal generated by reproducing the expansion video signal into a main image reproduction video signal based on the first video data and information incorporation mark image reproduction video signal based on the second video data. The separated information incorporation mark image reproduction video signal is decoded into operation control data directly readable by the controlled object external device (62) and outputted to the controlled object external device (62). With this, in the field of the video application technology using recording media, information relevant to a video can be outputted to an electronic device outside a video player system, and the function expansion including anticipation of link control of the electronic device can be realized. Thus, such video incorporation controlled object external device controller is provided.
