Abstract: A headphone control system for use within a headphone includes a temperature sensor for detecting whether the circumference temperature of the headphone is relatively far from the human temperature implying the headphone is no longer worn by the user, and a gravity sensor for detecting whether the headphone is stationary implying that the headphone is not used for enabling a power saving mode, or is moving implying that the headphone is not yet unused for maintaining operation. The detection constantly is applied to the headphone disregarding whether the headphone is in an operation mode or a power saving mode so as to efficiently have the headphone operated in response to currently using or power-saved in response to non-using.

Abstract: The present invention relates to a luminous electric wire comprising at least one conductor component and an outer sheath for surrounding the conductor component. The outer sheath has at least one recess. The recess is filled with luminous materials. Under the natural light, the fluorescent light and ultraviolet, the luminous electric wire of the present invention stores energy.

Abstract: A bicycle fender allowing different color selection includes a frame and a panel. The frame has a body at the periphery formed in a shape of the fender, and at least one carved out zone and at least one fastening element to be coupled with the panel to form changeable color and pattern combinations that can be selected and installed according to users' requirements and preferences.

Abstract: A fender fastenable to a bicycle bracing post includes at least a fender body and a fastening assembly. The fender body has a front section on which a concave portion, a slit and a holding space are formed. The slit can be opened elastically to allow a bicycle rear fork to be held in the holding space. The fastening means and the fender body can be coupled and adjusted to quickly install the fender on the bicycle bracing post. As a result more space is available to hold other bicycle accessories.

Abstract: The object of this invention is to provide a safety pneumatic tire for the bicyclist. The new safety pneumatic tire comprises an improved outer cover (or tire) and an improved inner tube. The improved inner tube is incorporated inside the improved tire and both are mounted on a tubeless rim (rather than a traditional rim). A) The improved tire consists of an elastomeric material coating that is applied to the beads of the tire to obtain an elastic property. The elastomeric-covered beads and the tubeless rim naturely join closely to form a completely sealed chamber between the tire and the tubeless rim. B) The improved inner tube consists of an elastic rubber part that is added to the outer base of the air valve body or is added to the entire outer body of the air valve to form an air tight seal with the rim valve opening.

Abstract: A fan control system. The fan motor is operated normally at not greater than a preset maximum rotation speed. The fan control system has a programmable microcontroller to receive an input voltage and a rotation speed signal corresponding to the actual rotation speed of the fan motor, determining an output signal according to the input voltage and the rotation speed signal, and outputting the output signal; and a fan-driving unit to receive the output signal and adjusting the rotation speed for driving the fan motor according to the output signal. When the rotation speed is lower than a predetermined rotation speed, the rotation speed is in a relation of a first function to the input voltage; when the rotation speed is greater than the predetermined rotation speed, the rotation speed is in a relation of a second function to the input voltage.

Abstract: A threaded screw with cutting notch structures thereon comprising a screw body and a plurality of screw threads provided along the screw body, characterized in that at least two notches, corresponding to each other are provided at the front end of the screw body, the interior space of the notch is tapered upward from the bottom forming into a slanting cut face and a cut wall, and the slanting cut face is corresponding to the cut wall and forming an inclination angle of 91 to 119 degree, thereby when the end portion of the first screw thread is screwed into a locking element, the screw threads are easily screwed in the locking element with the cut wall cuts the locking element and the debris of the locking element can be expelled by the space of the cutting notch and a lower resistance allowing a faster screwing process into the locking element.

Abstract: The invention relates to a light detecting system for detecting light projected from a projector. When the projector is initiated, it will project a picture image forward. The light detecting system comprises a frame positioned at a predetermined position in front of the projector, a detecting device movably installed on the frame for detecting the picture image, a driving device installed on the frame for moving the detecting device, and a control device connected with the driving device and the detecting device for controlling the driving device to move the detecting device to various sampling positions on the frame and to control the detecting device to detect the picture image at each of the sampling positions.

Abstract: A fixing device for use on a bicycle to removably secure a universal mudguard to the rear wheel of the same. The mudguard is provided with a ball-shaped supporting member at one end thereof. A pair of symmetric clamping pieces are removably secured to the seat pillar of a bicycle by a fastening bolt and nut. Each clamping piece has a semi-spherical cavity on the inner wall thereof, having radially extended protrusions in correspondence to the ball-shaped supporting member, so as to permit the supporting member to be adjustably retained therein.
