Abstract: A UAV tethering system provides an environment in which to fly an unmanned aerial vehicle (UAV) where the tether is selected to prevent the UAV from unintentional contact with the ground or other objects within the flight area. A tether may connect the UAV to a shuttle that slides along a track. The tether may be used to provide efficient, robust and accurate positioning information. The system can be configured to detect the angle at which the tethering line extends from the shuttle, the length of the extended tethering line, and then compute the position of the UAV relative to the shuttle. Furthermore, by knowing the position of the shuttle, the absolute position of the UAV can be determined.

Abstract: A wheel alignment angle measuring apparatus according to the present invention computes variation energy sums EA? and EB? and a reference wheel referencing alignment angle (a toe angle TBR) based on an anteroposterior force variation rate dFx and a lateral force variation rate dFy generated in a reference wheel (RL). Furthermore, the alignment angle measuring apparatus computes a non-reference wheel referencing alignment angle (a toe angle TNBR) of a non-reference wheel (FL), and then computes a toe angle TNBA to be specified for the non-reference wheel, based on the toe angle TNBR and a difference between a toe angle TBR and the toe angle TI.

Abstract: The invention makes it possible to measure a lateral displacement amount of a vehicle accurately in a short time on a bench testing machine without damaging a vehicle body and tires. Respective rollers 1F, 1R on which respective wheels WF, WR of the vehicle A are placed respectively are made movable in a lateral direction. In a state in which the respective wheels WF, WR are rotating at a predetermined speed, lateral forces (cornering forces) acting on the respective rollers 1F, 1R are detected by respective detectors 3. Then, a yaw angle speed when the vehicle A is brought into a state of steady circular turning is calculated based on the lateral forces acting on the respective rollers 1F, 1R and the lateral displacement amount is calculated from the yaw angle speed.

Abstract: A method for measuring side run-out of a wheel by turning the wheel mounted on a roller supported rotatably. It is judged whether or not the difference between the side run-out of a wheel at the start point onf one turn and the end point of one turn falls within a specified range or not. If it falls within the specified range, the difference between the maximum and minimum values of the side run-out during rotation is defined as the side run-out of the wheel. Even if the wheel is displaced during measurement to cause variation in the measurement value of the side run-out, the varied measurement value can be removed and highly accurate side run-out and side run-out width can be obtained.

Abstract: A system for measuring caster trail of a wheel. The system comprises position sensing devices for sensing positional signals of the wheel and a data processing system configured to couple to the position sensing devices. The data processing system receives signals from the position sensing devices and determines spatial characteristics of a steering axis of the wheel, a reference plane and the center of a wheel. The system then determines the caster trail based on the spatial characteristics.

Abstract: A wheel alignment adjusting device is provided in which loading portions, on which wheels of a vehicle are loaded, can be positioned with high accuracy. Front and rear tire driving devices 118 at a vehicle transverse direction left side are fixed to a loading stand 18. Front and rear tire driving devices 118 at a vehicle transverse direction right side are mounted to a first sliding base 34R. The first sliding base 34R is movable in a vehicle transverse direction with respect to the loading stand 18. When a vehicle transverse direction distance between the tire driving devices 118 is to be changed in accordance with a tread base of the vehicle, the first sliding base 34R is moved. Only the tire driving devices 118 at one vehicle transverse direction side are moved, rather than the tire driving devices 118 at both vehicle transverse direction sides. Thus, a structure of the wheel alignment adjusting device is simplified because a number of driving devices for moving the tire driving devices 118 is reduced.
