Abstract: A headlight of motorcycle includes a dashboard, a connection member, a headlight, a bracket, and front support racks. The dashboard is coupled to the headlight by the connection member in a modularized manner. The headlight forms coupling holes for mounting to the front support racks. The bracket carries signal lights thereon. By coupling the headlight and the dashboard together in a modularized manner and mounting the bracket that carries the signal lights to the opposite sides of the headlight, and further fixing the front support racks to the opposite sides of the headlight, a headlight module is formed. The headlight module can be easily attached between upper and lower beams of a steering handlebar by using the front support racks so as to simplify the assembling operation and to conceal the front support racks between the bracket and the steering handlebar for improving the outside appearance of the headlight.

Abstract: A direction and speed control device for an electronic wheelchair includes: a base member mounted on the electronic wheelchair; a manually operable pointing unit mounted on the base member and including a control stick pivotable relative to the base member; first and second three-axis g acceleration sensors, each generating a voltage output indicative of tilt of a respective one of the control stick and the base member in three orthogonal axes; and a control unit operable so as to process the voltage outputs of the first and second three-axis g acceleration sensors to generate corresponding control signals for controlling rotation direction and speed of a wheel unit of the electronic wheelchair.
