Abstract: A light source inside a back light module comprising a red light-emitting diode, a green light-emitting diode, a blue light-emitting diode, a diffusion device, some supporting elements and reflectors is provided. The red, green and blue light-emitting diodes mount on a holder. The diffusion device is set up over the holder. The diffusion device comprises a transparent body and a plurality of fine particles distributed within the transparent body. The supporting elements are positioned between the diffusion device and the holder. The reflectors are attached to the surface on each side of the holder and the diffusion device. Red, green and blue lights from various light-emitting diodes are thoroughly mixed inside the diffusion device to form a uniform white light.

Abstract: A power driving device is incorporated in a cart for assisting in moving the cart. The power driving device includes a motor mechanically coupled to at least a wheel of the cart for driving the wheel. A torque detector is mounted in the cart to detect a torque resulting from a force applied by a user to move the cart and to generate an electrical signal corresponding to the torque detected. The signal is applied to a controller that is electrically connected to the motor. The controller controls the operation of the motor based on the signal received thereby ensuring a proper operation of the motor. A power supply is electrically connected to the controller for powering the power driving device and the motor. The controller controls the power supplied to the motor and thus protects the power supply from over-discharge.

Abstract: A dual motor driving control system is incorporated in an electrical vehicle having a front wheel and a rear wheel. The control system includes first and second motors respectively and mechanically coupled to the front and rear wheels of the vehicle for separately driving the wheels. A central control device includes a single chip microprocessor executing control software to selectively perform at least one predetermined motor control model. The central control device has output control units electrically coupled to the motors to control operations of the motors based on the motor control model performed in the mircroprocessor.
