Bank angle sensor
First Claim
1. A tilt angle sensor for a motor vehicle, including:
- a body, a cavity formed in said body and having a pair of inclined surfaces which intersect to define a lower end of said cavity;
roller means formed of a magnetic material disposed in said cavity;
a Hall effect sensor for sensing the presence of said roller means in the lower end of said cavity and being operative for changing a first signal when said roller means is displaced from the lower end of the cavity;
a timing circuit coupled to the sensor for commencing a timing cycle upon the occurrence of said first signal and for providing a second signal after a predetermined time delay; and
a latching circuit coupled to the timing circuit for latching an output device upon the occurrence of the second signal.

Abstract
A tilt angle sensor has a body which includes a V-shaped cavity defined by a pair of inclined surfaces which intersect to define a lower end. A roller is disposed in said cavity. A sensing circuit is associated with the cavity to sense the presence of the roller in the lower end of the cavity. The sensing circuit initiates a first signal when the roller is displaced from the lower end of the cavity. A timing circuit is coupled to the sensing circuit for commencing a timing cycle upon the occurrence of the first signal and for providing a second signal after a predetermined time delay. A latch mechanism coupled to the timing circuit latches an output device upon the occurrence of the second signal.
