Abstract: A length measuring apparatus is provided that combines upper data with lower data and then outputs the composite data. The apparatus monitors taking down or up a digit of upper data or lower data and synchronization of lower data, thus preventing an occurrence of reading error. When an A/D area showing an area of lower data matches with an upper area quadrant showing an area of upper data (R2, R3), the upper count value outputting the upper data is output without any change. When the quadrant (0, 1, 2, 3) of the A/D area does not match with the quadrant (0, 1, 2, 3) of upper area because of an erroneous timing of a digit-taking-up of upper data (R1, R4), +1 or −1 is added to the upper count value. Thus, the continuity of a measured value can be obtained when the scale is being moved.

Abstract: An automatic plumb, level, pointing and distance measuring tool uses a visible laser diode to project a beam in any of several different modes through a beam exit window. The tool, approximately the size and shape of a tape measure, can be placed on one edge to project a tilt-compensated vertical beam. Placed on another edge 90.degree.-rotated, the tool projects through the same exit window a tilt-compensated horizontal beam. When laid on either of its larger flat sides, the tilt compensation becomes inoperative and the tool projects a beam which is fixed relative to the housing. Acoustic distance measurement is facilitated using a second component or target side device which receives both a light beam an acoustic signal simultaneously projected from the laser tool across a space to be measured. A receiver in the target side device first detects arrival of a characteristically modulated or pulsed light beam, received at a photodetector on the target side device, and then receives the acoustic signal.

An anchoring fitting is inserted into the base-forming cavity so that a portion thereof will be encapsulated in the material forming the base. After all the components of the marker are received within the mold, it is heated to fuse the fusible material within the mold into an integral whole.

Abstract: Traction apparatus for driving a vehicle and accurately sensing the distance traveled, in which a drive mechanism is encircled by a separate ring-shaped encoder wheel. The encoder wheel, which is part of a travel-sensing mechanism, nests annularly with the drive mechanism so that the width of the combination is minimized. The travel-sensing mechanism can be assembled to the vehicle without disturbing the drive mechanism. There is enough radial clearance in the toroidal encoder wheel to permit the drive mechanism to move up and down within the encoder wheel. The encoder wheel has approximately the same outside diameter as the drive wheel, so certain common-mode measurement errors cancel. The encoder wheel and the drive wheel are approximately concentric and closely spaced laterally to minimize measurement errors that would otherwise occur upon turning of the vehicle.
