    摘要： A distance meter circuit includes: a driver for generating a driving pulse according to a measuring control signal to drive a laser diode to emit a light pulse to an object; a photonic sensing device for generating a first light conversion signal in response to the light pulse reflected by the object; a read-out circuit for measuring a TOF of the light pulse reflected by the object; an adjustable delay circuit for providing an adjustable delay time between the measuring control signal and the measuring trigger signal, or between the measuring control signal and the driving pulse; and a DLL controller for generating a delay control signal by comparing a phase difference between the measuring trigger signal and a driving related signal related to the driving pulse such that the phase difference is regulated to a predetermined value.

    摘要： A proximity sensor includes: a transmitter unit for transmitting a light signal; a receiver unit for receiving the light signal reflected by an object to determine a proximity status of the object; and a housing defining a first enclosed accommodation space for accommodating the receiver unit, wherein the portion of the housing which defines the first enclosed accommodation space has a sealed light passage made of a light-transmissible material such that the receiver unit is capable of receiving the light signal reflected by the object through the light passage. The housing can further include a second enclosed accommodation space for accommodating the transmitter unit.

    摘要： The present invention discloses a wearable device with combined sensing capabilities, which includes a wearable assembly and at least one multi-function sensor module. The wearable assembly is suitable to be worn on apart of a user's body. The wearable assembly includes at least one light-transmissible window. The multi-function sensor module is located inside the wearable assembly, for performing an image sensing function and an infrared temperature sensing function. The multi-function sensor module includes an image sensor module for sensing a physical or a biological feature of an object through the light-transmissible window by way of image sensing; and an infrared temperature sensor module for sensing temperature through the light-transmissible window by way of infrared temperature sensing.
