Abstract: A laser control apparatus that controls a laser device acquires state data from the laser device indicating the state of the laser device every time a specific preset event occurs, such as the generation of a fixed number of discharge pulses, for example, and transmits this data to a monitor terminal. The monitor terminal transfers the received state data to a server device via a communication channel. In the server device, a database is updated and output data is generated based on the transferred state data. This output data is input to a display terminal via a communication channel, and is displayed on the display terminal.

Abstract: There is provided a vehicle interference prevention device that, by computing a range of possible locations of a vehicle taking into consideration the time at which the location of the vehicle is measured, can safely predict the location of the vehicle, even with minimal frequency of radio contact, and prevent interference among unmanned vehicles or manned vehicles over the entirety of large work site. An unmanned vehicle uses the latest position data for a manned vehicle acquired (received) via an inter-vehicle communication device to determine a position (position at a certain point in time) as the basis for computing a circle having this position as its center and having a radius equal to the distance traveled at maximum speed from this point to a predetermined future point in time, and designates the area within this circle on a prearranged travel route as a range of possible locations for the manned vehicle. The unmanned vehicle then decides whether its own vehicle position interferes with this circle.

Abstract: An engine enclosure for a construction vehicle which is simply constructed and small-sized, while improving the cooling efficiency and lowering the noise. The engine enclosure including: an engine hood 15 having an ambient air inlet port 24; and engine side covers 16 having ambient air inlet ports 38. The engine enclosure is constructed to include an ambient air screening wall around a muffler 5 so that the cooling ambient air taken from the ambient air inlet ports 24 and 38 may flow to a fan without contacting with the muffler 5. With this construction, the air around the muffler and especially at a high temperature in the engine room and the cooling ambient air taken from the engine hood and the engine side covers can be screened from each other so that the temperature rise in the cooling ambient air to be fed to a heat exchanger such as a radiator can be reduced to improve the cooling efficiency.
