Patents by Inventor Ian K. APPLETON

Ian K. APPLETON has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10411717
    Abstract: A device and method is presented to allow the high frequency clock generators and functional blocks of a wireless communication device to enter a very low power sleep state while the low frequency reference clock generator within the wireless communications device remains in an active state. The timing block provides methods of increasing and maintaining accuracy of the system timer which may have been reduced by temperature variation or manufacturing defects. The timing block also allows for selection of the highest accuracy clock from among multiple high frequency clock references. A device for timing control is presented comprising at least one high frequency reference clock, a low frequency reference clock and a timing controller for generating a system timer, wherein the timing controller selects one of the at least one high frequency reference clock and processes the low frequency reference clock with the selected high frequency reference clock.

  • Publication number: 20150163752
    Abstract: A method and apparatus for mitigating interference in A User Equipment (UE) is provided. The UE includes a Long Term Evolution (LTE) modem including a LTE transmitter and a Wireless Local Area Network (WLAN) station. The WLAN station is in communication with the LTE modem via a Coexistence Interface (CoI) which receives notification signals from the LTE modem indicating when the LTE transmitter is active and inactive. The notification signals and local context information associated with the WLAN station are correlated for generating a power control signal that is transmitted from the WLAN station to the LTE modem for controlling a power level of LTE transmissions.

  • Publication number: 20140313910
    Abstract: A method of, and a wireless transceiver and/or system for, detecting coexistence interference are described. The method includes receiving, by an antenna connected to a first wireless transceiver, a wireless signal including a first signal substantially within a first frequency band from one or more first wireless transmitters; acquiring measurement ? of a wideband signal, the wideband signal being a wired signal corresponding to the wireless signal received by the antenna; acquiring measurement ? of a narrowband signal, the narrowband signal being the result of mixing and filtering the wideband signal; and determining, based on measurements ? and ?, a level of coexistence interference between the first signal and a second signal substantially within a second frequency band substantially contiguous with the first frequency band, the second signal being transmitted by one or more second wireless transmitters collocated with the first wireless transceiver.
