DIFFERENTIAL MOTION SENSOR

摘要

A differential motion sensor (100) includes a base (102) and a cradle (104). The base (102) includes a first surface that extends along a first axis to define a length and a second axis to define a width. The base (102) further includes at least one hinge (110a) that pivots about a rotational axis extending along the first axis. The cradle (104) is pivotably coupled to the at least one hinge (110a) and is configured to move in the direction of the second axis when pivoting about the hinge (110a). The differential motion sensor is configured to operate in a first mode when the cradle (104) is aligned with the base (102) and a second mode when the cradle (104) is pivotably displaced with respect to the base (102).
