Abstract:
A safety system prevents cutting machine operators from being accidentally carried through the infeed chute into the machine's cutting mechanism. An operator wears a safety device on his wrist and/or ankle and a sensor array mounts on opposing sides of the cutting machine's infeed chute. The sensor array elements are wound in opposite directions and connect in series opposing. The magnetic field of the safety device induces a current in the sensor array as it moves in the proximity of the sensor array. The safety system generates a signal which is proportional to the sum of the induced currents. When the signal exceeds a threshold, the safety system shuts off power to the feed mechanism and/or the cutting blades of the cutting machine, preventing injury to the operator.

Claim (Index 1):
A safety system for a machine comprising:\n a sensor array comprising at least two sensor elements having conductive windings, each sensor element comprising a protective plate and a conductive winding, each conductive winding comprising at least one loop of wire, the sensor elements mounted on opposing sides of an infeed chute; a sensor circuit configured to sense a current induced in the conductive windings by a magnetic field of a magnetic safety device, the current induced by moving the magnetic safety device proximate to the sensor array, the sensor circuit further comprising an amplifier that generates an amplified signal proportional to the current; and a comparator to compare the amplified signal to a threshold value, wherein the operation of the machine is interrupted when the amplified signal is greater than the threshold value.
