Abstract
Operation of a materials handling vehicle is monitored for impacts by generating an electrical impact signal indicative of a force measurement electronically read from a sensor mounted on the materials handling vehicle, generating an electrical impulse signal indicative of a change of momentum of the materials handling vehicle, and outputting an electrical impact alarm signal when the electrical impact signal exceeds a selected force limit threshold and the electrical impulse signal exceeds an impulse signal limit within a predetermined time period.
