Abstract: A rotational speed/tip sensor combines a tip sensor and a speed sensor in one compact package for use on a motorcycle. The tip sensor includes a disk and a sensing device that detects the absence or presence of the disk in the apex of a V-groove. If the motorcycle tips over, the disk rolls out of the V-groove apex and actuates the tip sensing device to open a circuit through a speed sensing device and thereby shut down the motorcycle engine. The tip and speed sensors are assembled to a housing that is mounted to the engine. Only three wires are used to connect both the tip sensing device and the speed sensing device to the engine control.

Abstract: An alignment fixture and method including a support base, mounting brackets for supporting a part in a fixed position on the base, first and second laser transmitters mounted on the base and oriented in a fixed position relative to the part for projecting laser beams defining intersecting registration lines on the part.
