Patent GB-0901089-D0 (GB)
Title: Wireless communications methods and apparatus
Filed: 2009-01-22
Abstract: The invention concerns a multiple input multiple output (MIMO) system employing precoding. Information for transmission is represented by a data vector comprising corresponding data for each of the multi-antennae. A perturbation vector is applied to the data vector in order to generate a perturbed data vector. The perturbation vector is formed by multiplying together a diagonal matrix of positive real numbers and a complex integer vector. Each non-zero element of the diagonal matrix comprises a constellation shift parameter for a respective spatial stream. Conventional methods do not support different modulo shift parameters for different spatial streams — they use a scalar rather than a diagonal matrix. The perturbation vector is selected by solving an integer least squares problem such that a normalisation factor is minimised; this involves applying a scaling factor to the integer least squares problem.

Title: Electrically resistive tracks
IPC: H05B3/26
Filed: 1987-02-25
Abstract: A heating element (2) comprises an electrically resistive track intended to be formed on an electrically insulative substrate (4). A heating unit (10) comprises a heating element (12) and a temperature sensor (14) on a substrate (11), the sensor (14) comprising an electrically resistive track. The track (2,14) consists of a thick film having in the temperature range of from 0 DEG C to 550 DEG C a temperature coefficient of resistance in excess of 0.006 per degree C. The thick film includes a metal and a glass in such proportions as to provide a suitable resistivity and a thermal expansion coefficient to match that of an electrically insulative substrate to which the track is to be applied and to permit adhesion of the track to the substrate. The considerable variation of the resistance of the track with temperature provides advantages in both of the aforementioned applications.

Patent GB-9125616-D0 (GB)
Title: Bias stabilizing circuit
IPC: H03G1/04
Filed: 1991-12-02
Abstract: There is disclosed a circuit for stabilizing the bias of a paging receiver. An oscillation control signal of first period is generated at the time when a voltage source is connected to the RF components. An oscillation means generates a signal of the center frequency of a received modulated signal in response to the oscillation control signal. A demodulation means demodulates the signal of the center frequency so as to generate a signal of second voltage that is received by a waveform reshaping means to stabilize the bias into the level of the second voltage. The RF receiver converts the received RF modulated signal into a signal offset by a frequency deviation from the center frequency during second period after the termination of the first period. The demodulation means generates a demodulated signal of first or third voltage according to the logical state of the received modulated signal. The waveform reshaping means compares the received demodulated signal with the bias so as to generate a digital signal of a constant duty ratio.

Title: Data storage arrangement
IPC: G06F12/0802
Filed: 1993-12-01
Abstract: In a data processing system utilising fast-access cache memory, data words written in to the cache from main memory are immediately read and checked against the original, any discrepancies resulting in the lock-out of that cache location so that next time the processor calls up that data word it is again read from main memory and is written into another location in cache. The system is thereby tolerant of defective cache locations. <IMAGE>

Title: Mixtures of hexahydrotriazines useful as h2s scavengers
IPC: C07D251/04
Filed: 1993-09-30
Abstract: A mixture of amines made by reacting an amine compound with an aldehyde compound has been found to reduce the levels of H2S in liquid or gaseous hydrocarbon streams. At least one of the compounds must have an alkoxyalkylene radical. In one embodiment of the invention, the mixture of amines contains at least one hexahydrotriazine compound of the formula:    <IMAGE>  (i)  where R1, R2, R3, R4, R5 and R6 are independently selected from the group consisting of hydrogen and an alkyl radical, including substituted alkyl radicals, of 1 to 5 carbon atoms; where at least one of the groups is an alkoxyalkylene group. In another embodiment of the invention, the amine mixture may contain other by products, such as the monomers which make up the hexahydrotriazine, with or without the hexahydrotriazine being present. These materials are selective to the reduction of H2S levels in hydrocarbon or aqueous streams in the presence of CO2 which does not compromise their performance.

Date Jun. 26, 1997The present invention relates to a method for enhancing the time of response of an assay for a first bacterium, wherein: a) the first bacterium is exposed to infection by phage particles to which the first bacterium is permissive; b) the infected bacterium is treated to inactivate exogenous phage particles; c) the treated bacterium is cultivated in the presence of a second bacterium which is permissive to infection by the phage or its replicand and which has a doubling rate greater than the effective doubling rate of the first bacterium; and d) assessing the extent of plaque formation and/or of second bacterium growth in the cultivated second bacterium cells. The method can be used to assess the presence of first bacterium in a sample, notably where the first bacterium is a slow growing bacterium, such as Mycobacterium tuberculosis, where the method enables an operator to detect the presence of low amounts of the bacterium in sample within days instead of weeks as required by conventional cultivation techniques. The invention can also be used to assess the effect of a drug or other treatment on a bacterium or on a virus. The invention also provides a diagnostic kit for use in the method of the invention.

Inventor: SUNDHOLM LARS
IPC: B60N2/42
Filed: 2001-01-04
Abstract: The seat part (2) of the chair (1) contains a first cushion (4) in its rear section, which is initially filled with a medium (preferably air), and a second cushion (5) which is initially empty. The two cushions are connected to each other via at least one channel (6) provided with a one-way valve, which is opened when a pre-determined pressure is reached inside the first cushion. In the event of a collision, the bodyweight of the driver increases compression of the first cushion, causing the valve to open and the second cushion to fill with the medium. The second cushion is located symmetrically in the front of the seat part, next to the top side of the seat. As the cushion is filled with medium, it expands upwards and forces the drivers legs apart.  An Independent claim is also included for a method for preventing drivers legs being injured by a steering column, using this system.
