Title: System for extracting bitumen from diluted pipelined oil sands slurry
Inventor: BJORNSON BRADFORD E
IPC: B03B5/34
Filed: 2007-11-09
Abstract: An extraction system and process for extracting bitumen from a slurry containing bitumen, solids and water. The system comprises a cyclone separation facility for separating the slurry into a solids component stream and a bitumen froth stream with the bitumen froth stream including water and fine solids. The bitumen froth stream is then delivered to a froth concentration facility for separating the bitumen froth stream into a final bitumen enriched froth stream, and a water and fine solids stream. The final bitumen enriched froth stream is suitable for further processing. The system of the present invention is preferably mobile so that the cyclone extraction facility and the froth concentration facility can move with the mine face at an oil sands mining site, however, it is also contemplated that the system can be retrofitted to existing fixed treatment facilities to improve the operational efficiency of such fixed facilities.

Title: Nucleotide sequences mediating plant male fertility and method of using same
Inventor: WU YONGZHONG
IPC: C12N15/82
Filed: 2006-06-22
Abstract: Nucleotide sequences mediating male fertility in plants are described, with DNA molecule and amino acid sequences set forth. Promoter sequences and their essential regions are also identified. The nucleotide sequences are useful in mediating male fertility in plants. In one such method, the homozygous recessive condition of male sterility causing alleles is maintained after crossing with a second plant, where the second plant contains a restoring transgene construct having a nucleotide sequence which reverses the homozygous condition. The restoring sequence is linked with a hemizygous sequence encoding a product inhibiting formation or function of male gametes. The maintainer plant produces only viable male gametes which do not contain the restoring transgene construct. Increase of the maintainer plant is also provided by self-fertilization, and selection for seed or plants which contain the construct.

Abstract: A method is provided for multiple remote units (RU)s to efficiently utilize resources on a shared OFDM high speed data channel without collisions. A collision occurs when two or more RUs transmit on the same frequency at the same time. The method defines two distinct states for accessing the channel. These are the Arbitration state and the Data Transfer state. A base station transmits a flag on the downlink to notify the RUs of which state is in effect. RUs having a data message notify the base station by transmitting a frequency tone, which acts as a request to transmit data, during the arbitration state. The tone frequencies are frequency spaced to be mutually orthogonal, so that the base station can receive all the uplink requests simultaneously. Upon receiving the uplink request signals, the base station establishes the data transfer state and orders the uplink data messages from the remote units is a non-interfering sequence. A system for preventing uplink data message collisions in an OFDM communications system is also provided.

Title: System and method for improving smart card reader reconnections
Inventor: SINGH RAVI
IPC: G06K7/00
Filed: 2008-06-27
Abstract: Communications between a computing device and a smart card reader configured for communication with a smart card are facilitated through the use, by the computing device, of a smart card resource manager and a smart card reader service. The smart card reader service acts as a relay for commands between the smart card resource manager and the smart card reader. Appropriate configuration of the smart card reader service obviates a redundant downloading of certificates from smart card to computing device subsequent to loss of a connection between the computing device and the smart card reader. However, upon re-establishing a previously lost connection to a smart card reader and determining that a communication link between a smart card and the smart card reader has been ended and reestablished during the loss of connection, the smart card reader service may indicate to the smart card resource manager that smart card is absent and, subsequently, that the smart card is present.
