Abstract: An insulin-dosage detection device is arranged on a rotation member of an insulin injection pen having an injection button. The rotation variation of the rotation member corresponds to the injection dosage of the insulin injection pen. The insulin-dosage detection device has a circuit, a detection button, and a processor. The circuit, arranged on the rotation member of the insulin injection pen, outputs electronic signals in response to rotation of the rotation member. The detection button is connected to the injection button. The rotation member of the insulin injection pen rotates in response to the detection button and the injection button being pressed. The circuit rotates along with the rotation member. The processor, coupled to the circuit, calculates the rotation variation of the rotation member according to a first electronic signal and a second electronic signal respectively output from the circuit before and after the rotation of the circuit.

Abstract: A brightness control device for controlling light-emitting diodes (LEDs) during a video recording performed by an image sensor. The brightness control device includes a pulse width modulation (PWM) signal output unit and a brightness control signal generation unit. The signal output unit is configured to provide at least one PWM signal. The brightness control signal generation unit is configured to generate a brightness control signal according to an exposure signal of the image sensor and the at least one PWM signal.

Abstract: A method for distinguishing plaque and calculus is provided. The method is used in a device and includes the following steps: emitting, by a blue light-emitting diode, blue light to illuminate teeth in an oral cavity, wherein the blue light is used to generate autofluorescence of plaque and calculus on the teeth; sensing, by an image sensor, the autofluorescence of plaque and calculus; and distinguishing, by a processor, a plaque area and a calculus area on the teeth based on the autofluorescence.
