  • Patent number: 11106081
    Abstract: A light-emitting mechanism comprises at least one LED, an optical unit disposed on the LED, and at least one dimming unit disposed on the optical unit and corresponding to the LED. The dimming unit includes a shading component disposed directly above the corresponding LED, the size of the shading component is greater than or equal to the size of the LED below the shading component, and the adjacent shading components are not contact with each other. The invention also provides a backlight module including the light-emitting mechanism.

  • Patent number: 8634979
    Abstract: A drive device and a drive control method for the electric bicycle are disclosed. The drive device of the electric bicycle is equipped with a power supply/storage unit, a compact motor, an inclination sensor, a brake actuation sensor, a pedal-rotating speed sensor and a drive control module. The drive device performs integrated calculations using the inclination information of the inclination sensor, the brake actuation information of the brake actuation sensor and the pedal-rotating speed information of the pedal-rotating speed sensor, so the drive control modules instructs the compact motor and the power supply/storage unit to quickly enter an auxiliary drive mode for rotating wheels of the electric bicycle, or to enter an energy recovery mode for storing electrical energy generated by the compact motor.

  • Patent number: 8450959
    Abstract: The present disclosure related to a control method for a sensorless motor with energy recovery ability, using which duty cycle of a sensorless motor can be changed by the control of complementary switches so as to enable the sensorless motor to switch between a high efficiency driving operation and an energy recovery operation while being activated. Thereby, the conduction loss and the wear and tear to the switches can be minimized while simultaneously enhancing the energy recovery efficiency and thus improving the battery life.
