Abstract: A force transfer device 30 includes an inner race 40 and an outer race 38 and a plurality of reversible wedging elements 34 located between the inner and outer races. This device 30 allows for continuous force transfer between the inner and outer race. This device 30 further allows for locking the inner race 40 relative to the outer race 38 in infinitely varying positions. The device 30 includes scallops on at least one race which scallops are of complex shape in order to manage wedging of the wedging elements and surface stresses between the wedging elements and the race contact surfaces. The device 30 is also reversible.

Abstract: A plumb bob includes an asymmetrical device 22 and the bob weight 20. The asymmetrical device 22 includes a plug 20 which can be received in a cavity 24 of the bob weight 20. Appropriate material such as solder or an adhesive is selected for securing the asymmetric device 22 and the bob weight 20 in a manner that causes the center of gravity of the asymmetric device 22 to be aligned with that of the bob weight 20.

Abstract: A laser scanner 50 includes a laser 76 affixed to a pendulum 66 with a damper 80 for damping the movement of the pendulum 66. The laser scanner 50 is controllable through a remote control 62 for positioning the laser beam as desired. Both horizontal and vertical laser beams can be projected in order to orient the laser scanner 50 with respect to gravity and simultaneously elevation.
