Title: Polynucleotide analysis using combinatorial pcr
Inventor: HAMILL BRENDAN
IPC: C12Q1/6837
Filed: 2002-03-28
Abstract: The invention comprises a two-step process for analysis of polynucleotides b y chain extension of multiple oligonucleotide primers attached by 5'-linkages to solid supports by first performing PCR of the sample to be analysed in the presence of multiple oligonucleotides in solution, the nucleotide sequences of both sets of oligonucleotides being similar or identical. This produces immobilised single-stranded polynucleotides containing genetic sequence data derived from sample molecules. In a second step, support-bound polynucleotid es are interrogated by hybridisation with a single labelled oligonucleotide pro be or by second-strand synthesis with a primer-dependent polymerase using an oligonucleotide primer and nucleotide monomers, in which either or both of t he primer and nucleotide monomers are labelled. Incorporation of label demonstrates the presence of two separate defined-sequence primers within th e sample polynucleotide. The presence or absence within the sample of multiple combinations of primers are demonstrable in a single experiment by use of suitable apparatus, which may take the form of an oligonucleotide array. Multiple arrays may be accommodated in a 96-well format, allowing all possib le combinations of 96 different primers to be generated simultaneously. If sequence data forthe sample DNA is available in advance of the analysis, the results may be predicted by computer modelling, allowing design of highly- specific automated DNA-based assay procedures.
Patent CA-2445707-A1 (CA)
Inventor: OSHIMA MITSUAKI
IPC: H04N19/89
Filed: 1994-03-25
Abstract: At the transmitter side, carrier waves are modulated according to an input signal for producing relevant signal points in a signal space diagram. The input signal is divided into, two, first and second, data streams. The signal points are divided into signal point groups to which data of the first data stream are assigned. Also, data of the second data stream are assigned to the signal points of each signal point group. A difference in the transmission error rate between first and second data streams is developed, by shifting the signal points to other positions in the space diagram expressed at least in the polar coordinate system. At the receiver side, the first and/or second data streams can be reconstructed from a received signal. In TV broadcast service, a TV signal is divided by a transmitter into, low and high, frequency band components which are designated as a first and a second data streams respectively. Upon receiving the TV signal, a receiver can reproduce only the low frequency band component or both the low and high frequency band components, depending on its capability. Furthermore, a communication system based on an OFDM system is utilized for data transmission of a plurality of subchannels, wherein the subchannels are differentiated by changing the length, of a guard time slot or a carrier wave interval of a symbol transmission time slot, or changing the transmission electric power of the carrier.

Patent CA-2473639-A1 (CA)
Title: Fuel injection valve
Inventor: OVERSBY KEVIN
IPC: F02M61/18
Filed: 2004-07-09
Abstract: A fuel injection valve is provided for introducing a fuel into an engine and controlling fuel flow to reduce variability between injection events. The fuel injection valve employs an arrangement for a valve nozzle that cooperates with a valve needle. The valve needle and the valve body are shaped to cooperatively provide a constant flow area between the valve needle and the valve body. The constant flow area restricts flow through the nozzle so that mass flow rate is substantially constant for a range of valve needle movement within a predetermined range of needle movement. The method comprises commanding a valve needle to a position within the predetermined range of needle movement to reduce variability in the fuel mass flow rate, particularly when the engine is idling or operating under low load conditions. This improves injection consistency, thereby stabilizing engine operation, decreasing emissions, and increasing efficiency.

Inventor: HE GUANGMING
IPC: G01S13/74
Filed: 2004-08-09
Abstract: The distance measurement unit is used on a wireless personal security system to locate users who have initiated the help alarm or the attendance sequence. The distance measurement unit consists of a microcontroller, mobile transceiver key(s), a high speed counter, and base stations with transceivers.      The microcontroller controls the transceiver key(s) and the counter. The microcontroller will start the counter and cause the transceiver to transmit.  When the mobile transceiver key receives the data from the base station and answers it, the microcontroller will stop the counter. The distance between the mobile transceiver key and the base station is obtained by subtracting the time it has taken the transceiver and controller to process and transmit the data from the time that appears on the counter. The base station will also trigger nearby base stations to calculate the distance. The distances measured by the stations are used to locate the key(s) in question for security and/or attendance purposes. The distance measuring sequence is controlled by the master base station(s) to avoid any possible data collision.      Every base station has a map of nearby stations. So the point-to-point communication can be used, which will help to route the signal to control center faster and more reliably.

Title: Methods for storing data in non-volatile memories
Inventor: TORJUSSEN LARS SUNDELL
IPC: G11C29/00
Filed: 2003-04-10
Abstract: In methods for storing data in a non-volatile ferroelectric random access memory wherein destructive readout operations are followed by rewrite operations, identical copies of the data are stored in different memory locations that do not have any common word lines or alternative neither common word lines nor common bit lines. A first word line or a segment of a first word line is read in its entirety, said word line or said segment comprising at least a first copy of the identical copies of data. The data thus read are rewritten to the memory location and in addition transferred from the memory location in question to an appropriate cache location, whereafter subsequent memory locations either in the form of word lines or segments thereof are read, and data rewritten to the cache location. The operation is repeated until all identical copies of the data have been transferred to the cache storage. Subsequently bit errors are detected by comparing the identical copies in a memory control logic circuit, which also may be used for caching readout data copies or alternatively be connected with a separate cache memory. Corrected data are written back to the appropriate memory locations holding bit errors when the latter have been detected.
