Abstract of the Disclosure When the emergency stop button on the teaching pendant is pressed, the packet generating circuits 1 and 2 each prepare packet data relating to emergency stopping, and transmit this data to the robot control part by wireless communications via the transmission data switching circuit. Besides data indicating the need or lack of need for emergency stopping, a header or the like designating the packet receiving circuit to which the transmission is addressed is added to the packet data. The respective packet receiving circuits of the robot control part receive the respective sets of packet data in accordance with the designations of the headers. When the emergency stop button is pressed, emergency stop signals are output to a plurality of emergency stop control circuits from the respective packet receiving circuits immediately afterward, and a plurality of contacts connected in series are placed in a non-conductive state, so that the supply of motive force to the servo amplifiers is cut off, thus causing the robot to make an emergency stop.

An information terminal device (terminal) has a first radio communication unit capable of performing radio communication with low power consumption and a second radio communication unit performing data communication using a wireless LAN. In an ad-hoc mode in which data communication is performed between the terminals, as a rule, the second radio communication unit is set in a sleep mode. However, when actual data communication is necessary, an activation signal is transmitted to a terminal as a communication party by using the first radio communication unit to activate the second radio communication unit. After completion of data communication, a stop signal is transmitted to the terminal as the communication party by using the first radio communication unit to stop the second radio communication unit on the transmission side. In such a manner, transmission of a beacon signal from the second radio communication unit is suppressed, and proper power saving is realized.

A method and apparatus is provided for starting and stopping a high pressure spray washer having a combustion engine driving a pump to provide high pressure fluid to a spray gun activated by a trigger. Pulling the trigger causes water to flow through the nozzle and pump and a sensor by the pump sends a flow start signal to a control module that activates an electric starter when an engine switch is turned on, thus starting the engine when it wasn't running. When the trigger is released flow to the pump stops and the sensor sends a flow stop signal to the control module. If a predetermined time passes before the sensor detects fluid flow to the pump as occurs when the trigger is pulled, then the engine is shut off. The time can be varied to adjust the time between releasing the trigger and shutting off the engine.
