Material processing machine
First Claim
1. A material processing machine comprising:
- an operating region having at least one processing element in which material is processed by the at least one processing element;
an access region having at least one sensing coil, material passing to said operating region via the access region;
motive means driving the at least one processing element; and
control circuitry responsive to a signal from the at least one sensing coil to control at least one aspect of operation of the machine, wherein the at least one sensing coil generates the signal when at least one passive sensor carried by a user of the machine is in the access region.

Abstract
A material processing machine such as a wood chipping machine, a press, or other machine comprising an operating region having at least one processing element, and an access region through which material passes to the operating region, has at least one passive sensor that may be worn by a user of the machine, for example, around their wrist, and at least one sensing coil mounted in the access region of the machine for detecting the presence of the passive sensor in the access region. Control circuitry responsive to the at least one sensing coil provides control signals for stopping operation of the machine, preventing start-up of the machine and/or otherwise preventing injury to the machine user.
