Abstract: An improved electronic data recorder for use in a vehicle includes a housing having a pair of connectors. The housing encloses a modular converter, a printer module, a continuous roll of paper, a modular paper advance mechanism, conversion electronics, and memory and computation electronics. Also included in the housing are a driver code input keypad, a clock and date display, and keys for selecting a variety of functions. The data recorder connects to a free end of a rotatable odometer-speedometer cable between a rotating part of a vehicle to which the cable is attached and the vehicle odometer-speedometer. The data recorder also connects to the vehicle battery and ignition switch. The rotational motion of the cable is communicated into the housing of the data recorder by one of the connectors and from there into the modular converter. The converter converts the rotational motion into a plurality of unique electrical signals representative of mileage.

Abstract: A device for use in dividing a line into a predetermined number of equal parts. The device consists of a number of identical elongated links whose ends and centers are hingedly connected to form a set of extendable lazy tongs with preferably sixteen identical pointed rods attached to the hinged ends on one side of the set of lazy tongs. A case encloses the set of lazy tongs with the pointed ends of the rods projecting out of an elongated slot along the bottom of the case. One end of the set of lazy tongs is attached to one end of the case while the other end of the set of lazy tongs is attached to a slidable shaft which extends through a second elongated slot along the side of the case. The shaft is attached to a finger operated tab slidable along the second elongated slot for moving the lazy tongs and the pointed rods so that the pointed ends of two predetermined rods lie at the ends of a line to be divided into equal parts.
