ABSTRACT:
A substantially stationary sensor for providing an input signal to an electrical device based on the mechanical force applied to a sensor includes first and second laminar springs. The deflection of the laminar springs caused by the force placed on the sensor is measured by opto-electronic systems associated with each laminar spring. The output of the opto-electrical systems on each of two orthogonal axes is an electrical signal which is transformed into a signal usable by the electrical device. One specific application of the system is for a mouse used to control the position of a cursor on a computer screen.
