ABSTRACT:
A motion-sensing device for sensing tilt and acceleration when either tilt, horizontal acceleration, or tilt and horizontal acceleration acting concurrently, influence the device, including: a substrate, a first tilt sensor fixed to the top of the substrate; a pendulum flexibly coupled to the bottom of the substrate proximate to the first tilt sensor; and a second tilt sensor fixed to the pendulum. The first and/or second tilt sensors are preferably an accelerometer; a spring-mass system; and/or an arcuate resistive element. The first tilt sensor includes a tilt sensor that measures tilt in a first geometric plane, the pendulum is constrained to move in the first geometric plane, and the second tilt sensor is operable to measure tilt in the first geometric plane. The motion-sensing device or devices coupled to a machine, vehicle, and/or a control system. The substrate may include a portion of the first tilt sensor.
