  • Mobile device, and image processing method for mobile device
    Patent number: 10733706
    Abstract: An image processing method, suitable for a mobile device including a camera unit and a display unit, includes separating a foreground portion and a background portion of a first image sensed by the camera unit, calculating a dimension of the foreground portion, generating an adjustment level in positively correlated with the dimension, applying an image effect at the adjustment level to the foreground or the background portion of the first image to generate a second image, and displaying the second image on the display unit.

  • Communication circuit for flyback power converter with synchronous rectifier
    Patent number: 10158298
    Abstract: A method for communicating with a power converter comprises initiating a communication sequence by sensing a first distortion of a sensed waveform during a discharge period of a first power transfer cycle of the power converter. The sensed waveform is proportional to a secondary current of the power converter. At a primary side of the power converter, a data bit is received from a secondary side of the power converter, by sensing a second distortion to represent one state of the data bit and sending an absence of the second distortion to represent another state of the data bit. The secondary distortion is applied to the secondary current during the discharge period of a subsequent power transfer cycle.
