摘要： Systems and methods for positioning and navigating an autonomous vehicle (102,310) allow the vehicle (102,310) to travel between locations. A first position estimate (112) of the vehicle (102,310) is derived from satellites (132-170,200-206) of a global positioning system (100A) and/or a pseudolite(s) (105). The pseudolite(s) (105) may be used exclusively when the satellites (132-170,200-206) are not in view of the vehicle (102,310). A second position estimate (114) is derived from an inertial reference unit (904) and/or a vehicle odometer (902). The first and second position estimates are combined and filtered to derive a third position estimate (118). Navigation of the vehicle (102,310) is obtained using the position information (414), obstacle detection and avoidance data (416), and on board vehicle data (908,910).

摘要： PROBLEM TO BE SOLVED: To provide a snow cover meter permitting high-accuracy measurement and improved in safety. SOLUTION: This snow cover meter is provided with a laser light radiating means 20 for radiating laser light L1 to the surface of fallen snow S, a laser light receiving means for receiving laser light L2 radiated by the laser light radiating means 20 and reflected on the fallen snow, and an operating means for calculating the amount of snow cover d from data on the laser light L1 radiated by the laser light radiating means 20 and data on the laser light L2 received by the laser light receiving means 21. The snow cover meter is further provided with an object detecting sensor 3 for detecting the existence of designated objects 5, 6 in a designated range E, and an emergency stop means for stopping the radiation of laser light L2 by the laser light radiating means 20 when the object sensor 3 detects the objects 5, 6.

摘要： PROBLEM TO BE SOLVED: To provide a photoconductive switch capable of detecting only a specified object for a moving body, without providing a separate synchronizing unit or without having to stop the body. SOLUTION: The level S of the quantity of received light varying in time with approach of a body 3 moving on a transport line 10 goes within a judging range via a lower limit level stored in a lower limit level memory 30c. As the body 3 moves away in this condition, a level S of the quantity of received light re-travels out of the judging range via the lower limit level. Based on this, a control circuit 21 judges whether the body 3 is a desired object to be detected.
