<p>MULTI-AXIS POSITION DETERMINING SYSTEM of the Invention A position determining device having a distributed sensing element, such as a delay element, positioned at a selected angle greater than 0.degree. with respect to at least one selected direction along which a position is to be measured. Means for determining the position along the distributed element are provided, e.g., a driver transducer and a receiver transducer relatively movable along the delay element by which the delay of a signal travelling along the delay element and, hence, the position therealong is determined. Means responsive to such position determination are further included for calculating from such position determination the position along the at least one selected direction. The invention is especially useful for multi-axis position determination wherein, for example, a single delay element can be positioned at a selected angle with respect to each of two axes, so that linear or angular position determination can be made with respect to each axis.</p> |
