  • Publication number: 20180007697
    Abstract: The disclosure relates to a method for mitigating interference of a first radio signal received by a first transceiver of a first radio access technology (RAT) due to transmission of a second radio signal by a second transceiver of a second RAT, wherein the first transceiver and the second transceiver are physically collocated on a same device. The method includes: pre-setting a power of the second radio signal based on a throughput performance requirement for the first radio signal before transmission of the second radio signal, and tuning the power of the second radio signal during transmission of the second radio signal based on estimating the interference of the first radio signal.

  • Patent number: 9805287
    Abstract: A method of identifying relevant areas in digital images is provided. The method comprises receiving information representative of pixels in a first digital image, and calculating a spatial statistical measure of said information for groups of neighboring pixels in said first image to form a group value for each group of pixels. Further, the method comprises calculating differences between group values, and comparing said differences to a predetermined threshold value. If said difference is equal to or above said threshold value, said group is identified as relevant, and if said difference is below said threshold value, said group is identified as not relevant. A method of encoding digital images based on the identification of relevant and non-relevant areas is also provided, as well as a digital encoder system.

  • Patent number: 9553686
    Abstract: Example embodiments provide a compression method for TDM frames transported over a packet network. The method is based on mapping of allocated TDM slots but not all un-allocated slots into a transport structure, which thereby reduces the needed amount of data transported over packets and hence reduces the required packet rate and packet capacity during transport of the TDM frame. The mapping is further arranged to allow dynamic changes of packet rate and packet capacity, thus the mapping is performed such that a working size of the transport TDM frame is allowed to increase or decrease over time.

  • Patent number: 9552094
    Abstract: An electronic device with a touch screen display that includes capacitive sensing to determine the point of contact between the display and an input device. The device also includes a graphics circuit for rendering images on the touch screen display. The graphics circuit may be inactivated when not in use. The inactive mode provides a variety of advantages, such as a lower power drain on the power source. The device is further configured to sense the approach of an input device in proximity to the display. The device is configured to start activating the graphics circuit upon sensing the approach of the input device prior to contact with the display. The timing of the activation improves responsiveness of the electronic device.
