According to one embodiment, a wireless terminal communicates with a server via wireless base stations. The wireless terminal has devices which transmit a signal in a normal-power transmission mode and the signal in a low-power transmission mode, a power control device which switches the normal-power transmission mode to the low-power transmission mode, or vice versa, and a device which transmits current position data to the server. The server detects the position of the wireless terminal, designates one of the base stations which is close to the wireless terminal, when the wireless terminal is set to the low-power transmission mod, and detects whether the base station designated has a problem or not according to detect the signal from the wireless terminal.

In a parts mounting apparatus, a suction nozzle is caused to perform a cycloid movement. A part such as an electronic part is sucked into the nozzle at one of bottom dead points of the cycloid movement and mounted onto another component such as a circuit substrate at the other or another bottom dead point. In compensation of the position of the nozzle at the bottom dead point, the nozzle is also caused to perform the cycloid movement. The position of the nozzle at the bottom dead point is monitored by a monitoring camera so that an amount of deviation of the position of the nozzle from the bottom dead point is obtained. The phase of the cycloid movement is compensated so that the amount of deviation of the nozzle is rendered zero. Alternatively, the part sucked in the nozzle positioned at the bottom dead point is monitored by the monitoring camera.
