  • Patent number: 8948063
    Abstract: The subject matter disclosed herein relates to a system and method for estimating transmit chain and receive chain processing delays by a first wireless device. In a particular implementation, a first signal may be wirelessly transmitted from a first wireless device and at least a portion of the first signal may be received by a receiver of the first wireless device during transmission of the first signal. A first transmit processing delay and a first receive processing delay associated with the first signal may be measured or determined based at least in part on the receipt of the at least a portion of the first signal during the transmission of the first signal.

  • Patent number: 8655400
    Abstract: In user equipments (UEs) with multiple radios, interference between those radios may be reduced by monitoring radio performance and adjusting aggressor transmit power levels to ensure victim and aggressor performance stay within desired operational levels. Various factors may determine when a reduced power approach is desired. Such factors may include aggressor transmit power, received signal strength indicator, victim error rate, throughput loss, coverage impact, etc. Various methods of reducing transmit power may be used. For example, for Long Term Evolution communications, a power headroom report may be altered to adjust a modulation coding scheme and bandwidth allocated for a particular UE. For Bluetooth communications a power control mechanism may be overridden to ensure a device stays within a desired transmit power. A power reduction loop may be employed to monitor a device's transmit power.

  • Patent number: 8582478
    Abstract: A frequency division (FD) multiplexing device includes a multiplexer including a band-pass and a band-stop filter, the multiplexer is communicatively coupled to an antenna, the band-pass filter is configured to allow pass band frequencies to pass un-attenuated and to attenuate signals outside of the pass band. The band-stop filter is configured to attenuate signals at frequencies in at least a portion of the pass-band and allow frequencies outside the pass-band to pass un-attenuated.

  • Publication number: 20130244285
    Abstract: Methods and systems for acoustically treating material using a continuous process in which material may be caused to flow in a continuous or intermittent fashion into/out of an acoustic treatment chamber where the material is exposed to focused acoustic energy. The methods and systems may be arranged to permit continuous processing for extended periods while an acoustic energy source operates at a relatively high power output. Treatment chambers may include features such as an acoustic window, a heat exchanger, inlet/outlet flow arrangements, an inspection window, insert elements that define a treatment volume size or shape, etc. Treatment system configurations relating to arrangements of a treatment chamber relative to an acoustic source and coupling medium, material flow paths, and others are provided.

  • Publication number: 20130230080
    Abstract: A wireless communication device configured for receiving a wireless multiple-input and multiple-output signal. The wireless communication device includes a first multiple-input and multiple-output carrier aggregation receiver reuse architecture. The first multiple-input and multiple-output carrier aggregation receiver reuse architecture includes a first antenna, a second antenna and a transceiver chip. The first multiple-input and multiple-output carrier aggregation receiver reuse architecture reuses a first carrier aggregation receiver path. The wireless communication device also includes a second multiple-input and multiple-output carrier aggregation receiver reuse architecture. The second multiple-input and multiple-output carrier aggregation receiver reuse architecture includes a third antenna, a fourth antenna and a receiver chip. The second multiple-input and multiple-output carrier aggregation receiver reuse architecture reuses a second carrier aggregation receiver path.
