  • Publication number: 20190246910
    Abstract: The present invention provides an imaging-type heart rate monitoring device and method thereof. It acquires the human image information tracks the target area in the human image information, and extracts the target image in the target area. It transforms the human image information through the first frequency domain transform. It filters the residual noise of the continuous wavelet transform information. It rebuilds the residual noise filtered information by the continuous wavelet transform. It transforms the continuous wavelet transform rebuilt information by the Fourier transform. It obtains a heart rate value through the second frequency domain transformed information.

  • Patent number: 10289141
    Abstract: A method for generating a power distribution network (PDN) is provided. A heterogeneous circuit data is input. A plurality of horizontal power lines and a plurality of vertical power lines are determined according to the heterogeneous circuit data. A PDN model of the heterogeneous circuit is determined according to the horizontal power lines and the vertical power lines. Power consumption value is assigned to a plurality of internal nodes of the PDN model of the heterogeneous circuit. The PDN model of the heterogeneous circuit is adjusted to meet a target voltage drop limitation of the heterogeneous circuit data.
