Abstract: A remote control system operates automated equipment, such as a robotic device. The remote control system operates using an RF link and has both a "hard stop" control and a "soft stop" or "cycle hold" control. The system permits the technician or operator to work around a robotic device with the proximity switches deactivated without the necessity of being connected to the main control panel using a pendant device connected by cables.

Abstract: The emergency power shutdown system is especially adapted for use in an educational laboratory containing a plurality of items of potentially dangerous educational equipment. The system includes a portable transmitter unit adapted to be carried by the instructor in the laboratory and a control unit having a receiver fixedly mounted in the laboratory and capable of receiving the RF signal from the transmitter unit to actuate a relay-operated power shutdown unit to stop the flow of power through the system upon receipt of the RF signal from the instructor. The system provides for faster shutdown of the power supply system in an emergency situation, reducing the chance of injuries during operation of the potentially dangerous equipment.
