  • Patent number: 11874166
    Abstract: The present application discloses a light sensor circuit, which comprises a photodiode and a capacitor unit. The cathode of the photodiode is controlled by a capacitive unit to maintain the same or close voltage level as the anode of the photodiode, which significantly reduces the effect of the dark current of the photodiode. Thus, the light sensor circuit can effectively maintain the performance and accuracy of an analog-to-digital converter applying the light sensor circuit. The circuit design difficulty and manufacturing cost are also significantly reduced.

  • Publication number: 20140134011
    Abstract: An exemplary cooling fan includes a housing having an air inlet and an air outlet opposite to the air inlet, a rotor received in the housing, and a stator received in the housing and rotatably supporting the rotor. The rotor includes a hub, blades extending outwardly from an outer periphery of the hub, and flanges slantwise extending from top edges of end portions of the blades. In operation of the cooling fan, air located at an outside of the cooling fan enters the air inlet and flows towards the blades and along the flanges thereby pressing the rotor towards a bottom of the stator along an axial direction of the cooling fan, and the air subsequently flows out of the cooling fan via the air outlet.
