  • Patent number: 12092758
    Abstract: Method and apparatus for detecting a movement, such as two or more periodic vibrations, of a target, by sending a radar signal, e.g., near 60 GHz, at the target and processing the signal reflected by the target. One or more components of the movement can have a predominant frequency, such as a frequency of vibration, and two or more components can have different frequencies and, optionally, different magnitudes. A quadrature receiver processes the received signal to produce a base band output signal having in-phase (I) and quadrature-phase (Q) outputs. The in-phase (I) and quadrature-phase (Q) outputs are cross-referenced and real target movement frequency recovered directly in the time domain. System nonlinearity, which does not occur simultaneously on the I and Q channels, is identified and removed. Radar signals having wavelengths near one or more of the target movement magnitudes can be used.

  • Patent number: 7774031
    Abstract: A portable electronic device with an operation mode determined in accordance with power consumption and an operation mode switching method thereof are proposed. The method examines the voltage required by different systems to control every power system independently. By examining the capacity of a battery cell unit and comparing the capacity result with a first reference capacity and a second reference capacity, whether to offer operation power in order to operate a mobile communication module or a digital camera module is determined. Therefore, when a digital camera module, which has high power consumption requirements, is off, the mobile communication module can still operate to effectively use energy provided by the power supply unit.
