  • Patent number: 8952712
    Abstract: Methods and apparatus are disclosed to simultaneously, wirelessly test semiconductor components formed on a semiconductor wafer. The semiconductor components transmit respective outcomes of a self-contained testing operation to wireless automatic test equipment via a common communication channel. Multiple receiving antennas observe the outcomes from multiple directions in three dimensional space. The wireless automatic test equipment determines whether one or more of the semiconductor components operate as expected and, optionally, may use properties of the three dimensional space to determine a location of one or more of the semiconductor components. The wireless testing equipment may additionally determine performance of the semiconductor components by detecting infrared energy emitted, transmitted, and/or reflected by the semiconductor wafer before, during, and/or after a self-contained testing operation.

  • Patent number: 8954017
    Abstract: A communications device is disclosed that implements a phase-locked-loop to multiply a clock signal provided to a power management unit (PMU) by a variable integer value. Multiplying the PMU clock signal provides a second clock signal where the second clock signal is characterized by a fundamental component with one or more harmonics of the fundamental component that differ from the fundamental component and the one or more harmonics of the PMU clock signal. The fundamental component with one or more harmonics of the second clock signal does not occupy the same communication channel as the transmission communication signal of the communications device. Thus, minimizing the degradation of the transmission communication signal.

  • Patent number: 8954111
    Abstract: A wireless device has at least a first radio system for a first SIM channel and a second radio system for a second SIM channel. A processing system is arranged to determine whether a first of the first and second radio systems is capable of providing service for both of the first and second SIM channels currently being serviced by the first and second radio systems respectively. Servicing of the second SIM channel is transferred from the second radio system to the first radio system if it is determined that the first radio system is capable of providing service for both of first and second SIM channels. At least a part of the second radio system is shut down to reduce the power consumed by the second radio system after servicing of the second SIM channel has been transferred.

  • Patent number: 8954011
    Abstract: Aspects of a method and system for a wireless integrated power test and measurement are provided. In this regard, concurrently with receiving a first signal via a first antenna, a second signal that indicates received signal strength of the first signal may be generated and transmitted via a second antenna. The second signal may be utilized to determine performance of the first antenna. A frequency of the generated second signal may be controlled so as to mitigate interference between the transmitted second signal and the received first signal. The first signal may be formatted in accordance with one or more first wireless standards and the second signal may be formatted in accordance with one or more second wireless standards. The received signal strength of the first signal may be determined via an analog-to-digital converter and the second signal may be updated at the sample rate of the analog-to-digital converter.

  • Patent number: 8954538
    Abstract: A method and/or system are described in which a server communicatively coupled with a set-top-box (STB) may predict a location of a pointer on a web browser running on the STB. The server may render the pointer based on the predicted pointer location. The server may send the rendered pointer to the STB, wherein the STB may composite a web page on the web browser based on the rendered pointer. The server may be synchronized with the STB based on event information received by the server from the STB such as, for example, keystroke events, click event, or other like event. The prediction of the pointer location may be based on actual pointer location information provided by the STB. A predetermined number of pointer locations may be predicted based on an actual pointer location and/or on a latency of a connection between the server and the STB.

  • Patent number: 8953659
    Abstract: Response frame modulation coding set (MCS) selection within single user, multiple user, multiple access, and/or MIMO wireless communications. With respect to any exchange between communication devices in which there is a response frame, a first frame (e.g., an eliciting frame) is a first transmitted from the eliciting communication device to the responding communication device, and a second frame (e.g., a response frame) is transmitted from the responding communication device to the eliciting communities device. Appropriate selection of MCS to be used within the response frame may be determined explicitly or implicitly. One or more parameters (e.g., a limit parameter, a reduction parameter, etc.) may be used to determine the MCS of the response frame. The MCS employed for a response frame may be selected from a basic MCS set that ensures all response frames from any responding communication device may be properly received by the eliciting communication device.

  • Patent number: 8953930
    Abstract: A system and method for personal video recording (PVR) is provided for recording digitally encoded streams, and for playing back and decoding the recorded streams. The PVR system may receive the digitally encoded streams from a digital cable box or a network server. The system enables trick modes including fast forward and reverse mode displays at various speeds. The system an method for PVR may also be applied to digitally encoded streams without I-pictures, such as, for example, progressive refresh streams or HITS streams. Reverse decode and display may be implemented by starting at a suitable entry point, decoding quickly up to the point of the desired picture, and displaying the result, and repeating the process. Index tables of entry points may be used for proper operation in some modes where the entry points are entry pictures (E-pictures) which start a pattern of progressively refreshing I-slices.
