    摘要： A sensor (320) and method are provided for sensing gas absorbed in hydraulic fluid (370) in an aircraft shock absorber (350) where the hydraulic fluid (370) and a gas (360) are fluid communication with each other. The sensor may be incorporated in the shock absorber (350) or in servicing apparatus (300) such as a servicing cart. The amount of gas absorbed in the hydraulic fluid (370) is provided as a parameter which in combination with other parameters allows a user an improved means to determine the maintenance state of the shock absorber (350) and to derive servicing actions.

    摘要： A vehicle wheel assembly position measurement apparatus (1) measures, at each of at least three measurement positions in a circumferential direction, a distance in a vehicle width direction between each of plural measurement points located on a specified line that crosses a lateral surface of a tire section (23a) from an inner circumferential end to an outer circumferential end and respective one of distance measuring instruments (2) to (4), calculates an approximate curve indicating a relationship between a position in an extending direction of the specified line and the distance of each of the measurement points at the respective measurement position, calculates a rotation center position (O) of a wheel assembly (23) from a specific position of the approximate curve at the measurement position, and calculates a height position of the wheel assembly (23) relative to a vehicle body (22) from the rotation center position (O) and a height position of a specified portion of the vehicle body (22).

    摘要： A diagnosis system for the automatic diagnosis of the condition of predetermined components of a land vehicle has a diagnosis station (2) comprising a support base (5), which is fixed to the ground and is configured to support, approximately at ground level, at least two wheels (R) of the land vehicle (VT); and an image acquisition assembly (3), which is coupled to said support base (5) so as to be at least partly arranged, in use, under the land vehicle (VT) and is configured to acquire images, from below, of the predetermined components of the land vehicle (VT); and a control unit (4), which is configured to determine the condition, preferably the condition of wear, of the predetermined components of the land vehicle (VT) as a function of the acquired images.

    摘要： Systems and methods are provided for controlling the simulation of a coupled hybrid dynamic system comprising modeled components in a virtual model (70'; 70") and physical components (80'; 80"; 80' "), the virtual model (70'; 70") being a complementary system to the physical structural components (80'; 80"; 80' "), the virtual model (70') comprising model(s) of one or more disembodied assemblies, or the virtual model (70") being complementary to a plurality of disembodied physical assemblies. A physical test rig (72';72";72"') is configured to drive the physical structural components (80'; 80"; 80" ') and generate a test rig response comprising a first component (82'; 82"; 82' ") or coupling response (324) corresponding to an input to the virtual model (70'; 70"), and a second component (84'; 84"; 84" ') or convergence response (326) that is compared to an output of the virtual model (70'; 70"). A system dynamic response model (76') is obtained from the (82'; 82"; 82" ') or coupling response (324), the second component (84'; 84"; 84' ") or convergence response (326) and the virtual model (70') comprising model(s) of one or more disembodied assemblies, or the virtual model (70") being complementary to a plurality of disembodied physical assemblies.
