  • Patent number: 9927528
    Abstract: The disclosure describes methods of managing the power consumption of a GNSS receiver by identifying when to activate and deactivate the GNSS receiver, and by managing storage of GNSS location data points. In one embodiment, the GNSS receiver is activated if there is a change in wireless transmissions from stationary sources. In another embodiment, the GNSS receiver is deactivated when the GNSS signal quality is sufficient to calculate a GNSS location. In another embodiment, the GNSS receiver is deactivated for a time period in correlation with a GNSS speed. In yet another embodiment, redundant GNSS location data points are identified and only non-redundant data points are stored. In yet another embodiment, a GNSS device comprises a processor and a GNSS receiver configured to track GNSS signals and calculate a GNSS location. The GNSS receiver deactivates when the average signal quality value meets or exceeds the baseline signal value.

  • Patent number: 9685982
    Abstract: A mobile wireless communications device includes a housing an antenna, and radio frequency (RF) circuitry. A transceiver is connected to the antenna and a processor is operative with the RF circuitry. The transceiver includes an In-phase and Quadrature (I/Q) Modulation and Power Amplification circuit having an In-phase (I) circuit with a modulator mixer and power amplifier circuit. A Quadrature (Q) circuit includes a modulator mixer and power amplifier circuit. A power combiner receives the separately amplified In-phase and Quadrature signals and sums and outputs the signals as a combined I and Q signal. The I and Q circuits are isolated from the combined I and Q signal to enhance antenna matching and transmitted radiated power (TRP) and reduce harmonic emission from the power amplification circuits.
