Abstract: A laser engraving structure with three-dimensional effect formed on a plane, includes a substrate and at least one stacking sheets having a color different from a color of the substrate and attached on a processing surface of the substrate in order to form a multi-layered composite wooden material. In addition, the laser engraving technique can be utilized to the stacking surface of the composite wooden board in order to engrave out a desired pattern. Accordingly, a three-dimensional visual effect with great colors at different engraving depths can be achieved along with a gradient effect of different gray scale can be generated among layers of colors such that the texture is of rich colors and vividness.

Abstract: A wheel-locking suspension fork assembly for a bicycle includes first and second cylinder members coupled by a crosspiece disposed above a wheel, and a coupling joint turnably mounted on the first cylinder member and connected to a latch rod that is moved to be retained to a first catch unit on the first cylinder member so as to permit the wheel to freely rotate, or to a second catch unit on the second cylinder member so as to position between spokes of the wheel to lock the wheel. A key-operated lock is disposed in the coupling joint to be displaceable to a locking position where the latch rod is retained in the second catch unit.

Abstract: An apparatus for improving fuel efficiency of a vehicle is provided, including an engine, a generator system and an air-conditioning system. The generator system and the air-conditioning system are connected respectively through transmission elements and a moveable first active transmission wheel and a second active transmission wheel on the engine core axis. A first clutch is placed between the crank shaft of the engine and the first active transmission wheel, and a second clutch is placed between the first active transmission wheel and the second active transmission wheel. Also, a control circuit is provided to control the operation of the first clutch and the second clutch, in order to control the driving and rotation of the first active transmission wheel and/or the second active transmission wheel. The control circuit further determines according to the signal whether power is provided directly to the generator system and further drives the air-conditioning system.

Abstract: A vehicle-used composite braking/accelerating system is provided. In accordance with the composite braking/accelerating system, a movable motor is provided adjacent to a wheel of the vehicle. The movable motor is electrically connected to a control circuit and a battery. When the vehicle is moving and the moving vehicle is braked to decelerate, in which the driver of the vehicle slightly steps on the braking device, the control circuit instructs the movable motor to execute a generator function and drives the actuator to operate. The movable motor includes a coil member and a magnetic member. When the coil member and the magnetic member are correspondingly positioned and relatively rotated, the movable motor generates electrical energy, and saves the generated electrical energy into the battery. In such a way, the kinetic energy of the moving vehicle is transformed into electrical energy for saving the fuel consumption.

Abstract: A smart ETC system is provided. The smart ETC system includes a control circuit electrically connected to a battery, an ignition system, a vehicle speedometer, an ETC device, an automatic transmission, and a brake device. When a vehicle speed detector detects a vehicle speed lower than a predetermined value, the control circuit ignores a present gear, and outputs a neutral gear (N-gear) signal to an automatic transmission to shift the automatic transmission to an N-gear, and then instructs an ignition system of an engine to execute a switch-off instruction. Meanwhile, electric power consumed by all electric appliances is supplied by a battery. When the control circuit detects a signal indicating a battery level lower than a predetermined value, the control circuit outputs an instruction to the ignition system of the engine to restart the engine to charge the battery via a generator.
