Abstract: This invention comprises an improvement to motor vehicle lighting systems which enhances the safe operation of motor vehicles by communicating the operational state of the vehicle to operators of nearby vehicles. The system comprises an array of sensors to detect the operational condition of various components of a motor vehicle, and a computer which analyzes the outputs of the sensors, determines the operational state of the vehicle, and controls various displays which communicate the operational state information.

Abstract: This invention comprises a pedal (18) with engaging mechanisms (41) fixed thereon, and a cleat (10) affixed to a bicyclist's shoe by a clamp (101), thereby allowing the neutral position of the float to be adjusted and controlled and indexed. The cleat (10) is cylindrical, with fractionally cylindrical slots (12) formed thereon. The engaging mechanisms comprise a concave, fractionally cylindrical tongue (20) corresponding to the slots (12) in the cleat (10). Tongue (20) is spring loaded, and cooperates with the slots (12) in the cleat (10) to releasably capture the cleat (10) on the pedal (18). The fractionally cylindrical shape of the tongue (20) and slots (12) allow a predetermined and adjustable amount of float of the cleat (10) and the rider's foot, while remaining securely captured on the pedal (18).

Abstract: An apparatus for aligning bicycle wheel truing stands is disclosed having a gauge bar (10), hub pin (20), and gauge pin (30), which combine together to represent those certain parts, or features, or physical manifestations, or characteristics of a perfectly true, perfectly dished bicycle wheel, and being, by virtue of its construction and manufacture, accurate for use in aligning bicycle wheel truing stands.
