  • Publication number: 20110283171
    Abstract: A method of encoding a bit sequence over a Physical Downlink Control Channel (PDCCH) having Downlink Control Information (DCI) including: determining DCI bits to provide a DCI bit sequence; performing a CRC calculation on the DCI bit sequence to provide a CRC parity bit sequence; scrambling the CRC parity bit sequence to provide a scrambled CRC bit sequence; if the DCI format is LTE-A, further scrambling the DCI together with the attached scrambled CRC bit sequence to provide a LTE-A scrambled bit sequence; channel coding either the DCI attached scrambled CRC bit sequence or LTE-A scrambled bit sequence to provide a channel coded bit sequence; modulating the channel coded bit sequence to provide a modulated symbol sequence; layer mapping the modulated symbol sequence to one or more antennas associated with a transmitter to provide one or more layers having a symbol sequence; and precoding the layered symbol sequences.

  • Publication number: 20110216881
    Abstract: A method and system for using Threat Imaging Projection (TIP) technology, and the operator testing data that it generates, in order to certify x-ray inspection system operators and thereby assure an acceptable and uniform level of operator performance. In a preferred configuration, the operator views x-ray images of objects on a screening system equipped with TIP technology. When the operator believes that a threat item image appears on the screening system, the operator indicates such via an indicating means. The system is capable of recording, storing and transmitting individual operator performance data relating to proper detections, missed detections, and false alarms, i.e., when an operator indicates that a threat item image appears when no such image actually appears on the screening system. The system preferably contains a library of various threat item images, e.g., guns, bombs, knives, etc., which are classified according to type of threat and difficulty of detection.

  • Patent number: 7569584
    Abstract: The compound of the formula wherein the * indicates an asymmetric carbon, is specific to alpha2B adrenergic receptors in preference over alpha2A and alpha2C adrenergic receptors, and as such has no or only minimal cardivascular and/or sedatory activity. The compound is useful as medicament in mammals, including humans, for treatment of diseases and or alleviations of conditions which are responsive to treatment by agonists of alpha2B adrenergic receptors.

  • Patent number: 7362741
    Abstract: There is provided a method for use by a user equipment of a Universal Mobile Telecommunication System (UMTS) that supports HSDPA, and a network node in communication with such a user equipment. In an embodiment the method includes, identifying a transmission gap in a downlink transmission from a base station on a first channel. Next the transmission gap is mapped onto a first channel to define a first suspension period encompassing the subframes of the first channel that overlap the transmission gap. The method further includes expanding the first suspension period to define a further period encompassing the subframes of at least one further channel that overlap the first suspension period, and defining a reception suspension period encompassing the further period, and subframes associated with the subframes falling within the further period.

  • Patent number: 7313858
    Abstract: A Damascene process is provided for manufacturing a coil structure for a magnetic head. During the manufacturing process, an insulating layer is initially deposited after which a photoresist layer is deposited. A silicon dielectric layer is then deposited on the photoresist layer. After masking the silicon dielectric layer, at least one channel is etched in the photoresist layer and the silicon dielectric layer. Then, a conductive seed layer is deposited in the at least one channel. The at least one channel is then ready to be filled with a conductive material and chemically/mechanically polished to define a coil structure.
