Patent number: 8026845Abstract: A control module interconnecting a transmitter portion and a signal receiver portion of a mobile device is provided. The control module monitors the transmitter portion of the mobile device and, based on the monitored condition, alters the mobile device to inhibit the ability of a transmission signal from a transmitter to interfere with the signal receiver portion, i.e., intelligent blanking. In other words, the control module may disable or modify the signal receiver portion when power on the transmitter portion exceeds a predetermined power threshold level. Alternatively the control module may force the transmitter portion to transmit at a reduced power level.Type: GrantFiled: April 15, 2008Date of Patent: September 27, 2011Assignee: QUALCOMM IncorporatedInventor: Thomas G.

Patent number: 8018378Abstract: A satellite navigation receiver having a flexible acquisition and tracking engine architecture. The flexible acquisition engine has a reconfigurable delay line that can be used either as a single entity or divided into different sections. Consequently, it can be configured to search different satellite vehicles, a single Doppler frequency, and full CA code in parallel. When configuring the delay line into different sections, each section is used to search a partial CA code. In this configuration, multiple Doppler mode, multiple satellite vehicles, multiple Doppler frequencies, and partial CA code can be searched in parallel. Furthermore, the different sections of the CA code can be time-multiplexed into a correlator, which can then be over clocked to achieve full CA code correlation. The flexible tracking engine includes a number of parallel tracking channels, whereby each individual channel has a number of taps or fingers, which can be used to lock onto different delays.Type: GrantFiled: March 15, 2010Date of Patent: September 13, 2011Assignee: Atheros Communications, Inc.Inventors: Qinfang Sun, Wen-Chang Yeh

Patent number: 8013694Abstract: The invention relates to a small and low-voltage operable dielectric waveguide device. First and second electrode are embedded in a dielectric part and are formed to be thinner than a skin depth for a frequency of electromagnetic wave propagating along a first dielectric part included in the dielectric part. Thereby, even if the first and second electrodes are arranged to be in contact with the first dielectric part, the propagating electromagnetic wave can transmit the first and second electrodes, and therefore the electromagnetic wave can propagate without being cut off and there is no influence on waveguide modes of the electromagnetic wave. Further, in a state where a transmission loss due to the embedded of the electrode is suppressed, an electric field with large electric field strength can be applied to the first dielectric part by the first and second electrodes, and a small and low-voltage operable dielectric waveguide device can be achieved.Type: GrantFiled: March 30, 2007Date of Patent: September 6, 2011Assignee: Kyocera CorporationInventors: Nobuki Hiramatsu, Djuniadi A.
