Abstract
An adaptable tip sensor is useful for detecting the angular tipping of an object relative to a selected frame of reference. The sensor comprises a case that defines a two dimensional straight sided V-groove in which a disk can roll. A sensing device detects the presence or absence of the disk within the apex of the V-groove. As long as the object does not tip to a predetermined angle, the disk remains in the V-groove apex, and the sensing device produces a first signal. If the object tips to the predetermined angle, the disk rolls out of the V-groove apex, and the sensing device produces a different signal. Fluid in the case damps spurious vibrations. A labyrinth and air bubble in the case enhance desired rolling of the disk when the predetermined tipping has occurred.
