Abstract: An increased precision position sensor includes a first magnetic field sensing device; a second magnetic field sensing device; and a processor, the processor further includes a calibrator; a mathematical model to predict the magnetic field at a given position relative to the object; and an estimator algorithm to compare the measured magnetic field within the predicted magnetic field, thereby calculating the most likely position of the position sensor relative to the magnetic object. A position sensor in accordance with the invention is capable of locating the axis of a cylindrical magnetic object to within ±0.5 mm through 70 mm thick aluminium, and is expected to find application, in the aerospace industry, or other industries where high precision during manufacture is required. The invention may be conveniently embodied in a portable, handheld device.

Abstract: A movable vehicle headlight system for automatically aiming the headlights in the direction of travel regarless of the terrain of the road. The movable vehicle headlight system includes base assemblies each including a base member; and also includes headlight assemblies each including a headlight frame being securely mounted upon the base assembly and each including a headlight being pivotally mounted to the headlight frame; and further includes headlight drive assemblies for pivoting the headlight according to a terrain of a road being driven upon; and also includes a control unit assembly for controlling the headlight drive assemblies.
