Calibration device for dynamometric tools, such as for example a torque wrench (C) for tightening, comprising a sliding mechanical structure (2) associated with a frame of a test bench (B), which allows to impart a force and a controlled rotation in such a torque tool, said tool having its clamping tool (T) engaged in a brake (F) placed on the bench (B), which simulates a clamping of a bolt. Said mechanical structure comprises a pair of longitudinal bars (3) which can be connected to said bench, on which at least one guide (4) is mounted transversely, and on this guide there is a support (5) which slides by means of movement means in the transverse direction (Y) and is provided with constraint means for the tool body, so that the tool is pivoted on the brake (F) with its tool head (T) and can rotate to simulate a tightening brake F when the support (5) is moved along this guide (4). Said means for constraining the tool body to the support (5) comprise a slide (7) to which the handle (I) of the tool is fixed, which slides along a slider (8) parallel to the wrench which at one of its ends is pivoted on the brake fulcrum (F) and can rotate around it, said slider (8) being constrained to the support (5), so that the support (5) allows the slider and the tool to rotate together.

A service life testing device for a pressure sensor includes a first and a second plates, the first plate including a stage carrying a to-be-tested pressure sensor; a pair of drivers, two ends thereof respectively connected to the first and the second plates; a pair of linear slide mechanisms, disposed between the first and the second plates, and each including a slide rail and a slider moving there along, where a compression spring is disposed along an axial direction of each slide rail; a jig, disposed between the first and the second plates, and facing the to-be-tested pressure sensor; and a processing unit, electrically connected to the drivers and the to-be-tested pressure sensor, and configured to control a moving direction, a moving speed, and a moving stroke of the drivers, to cause the to-be-tested pressure sensor to press against or move away from a surface of the jig.

A method and system for detecting forces and moments acting on a vehicle wheel, wherein an outer ring of a wheel hub unit has a plurality of strain sensors configured to generate first signals (Ds1) proportional to mechanical stresses on the outer ring and a temperature sensor generating a second signal (Ds2). Further, the detection system comprises a second processing unit configured to process third signals (Dv1,n) corresponding to selected vehicle state parameters; and a third processing unit that receives the third signals and the pseudo-sinusoidal signal and calculates said forces and moments on the vehicle wheel.

An automatic robot control system and methods relating thereto are described. These systems include components such as a touch screen panel (“TSP”) robot controller for controlling a TSP robot, a camera robot controller for controlling a camera robot and an audio robot controller for controlling an audio robot. The TSP robot operates inside a TSP testing subsystem, the camera robot operates inside a camera testing subsystem, and the audio robot operates inside an audio testing subsystem. Inside the audio testing subsystem, an audio signals measurement system, using a bi-directional coupling, controls the operation of the audio robot controller. In this control scheme, a test application controller is designed to control the different types of subsystem robots. Methods relating to TSP, camera, and audio robots, and their controllers, taken individually or in combination, for automatic testing of device functionalities are also described.
