An apparatus and method for controlling equipment in response to a proximity signal from one or more chips and sensors for detecting proximity of an individual with respect to a manufacturing device. A chip (12a,12b) can be retained by an individual and a sensor (14a,14b) can be mounted on the manufacturing device (22a,22b). When the individual retaining the chip (12a,12b) comes into a predetermined proximity with the sensor (14a,14b), the sensor can emit a signal. The signal can be received by an electric control device (20a,2b) for disengaging operation of the machine or for placing the machine in a safe mode in response to the signal. The chip (12b) and the signal can interact in a first manner where the chip (12b) emits a signal receivable by the sensor. Alternatively, the chip (12a) and sensor (14a) can interact where the sensor (14a) emits a signal creating a field for identifying when a chip (12a) enters the signal generated field. <IMAGE> <IMAGE> |
