Abstract: An electronic hub odometer employs a permanent magnet and a magnetic reed switch for recording the number of revolutions of a vehicle wheel to which the odometer is mounted. A programmable integrated circuit electrically communicates with a clock crystal and the magnetic reed switch to automatically produce data relative to the time, distance and rate of travel of the associated vehicle. The data is stored in a random access memory integrated circuit. An infrared light emitting diode is employed for transmitting the data from the odometer to a remote unit. Information is also transmitted to the odometer from a remote unit via a photo-optical detector.

Abstract: The disclosed method features an automatic high production process of forming a socket wrench and other elongated hollow parts such as a nutdriver from a tubular metal workpiece. The method of making a nutdriver includes extruding a workpiece through a tapered female die to reduce both the inside and outside diameters at one end of the workpiece and along a predetermined portion of its length from that one end of the workpiece. A recess of non-circular cross section is formed at the other end of the workpiece. In the method of making a socket wrench, an additional step is included in forming another recess of non-circular cross section at the reduced end of the workpiece.
