A resistance sensing mechanism including a resistance adjusting unit including a holder frame, a locating sleeve disposed above the holder frame, an adjustment screw rod rotatably inserted through the locating sleeve and a screw nut threaded onto the adjustment screw rod and pivotally connected to the holder frame, and a sensor unit including a first linkage pivotally connected with one end to the screw nut, a second linkage having one end pivotally connected to an opposite end of the first linkage and an opposite end pivotally connected to the locating sleeve, a sensor mounted at one of the first and second linkages and a sensible member mounted at the other of the first and second linkages to face toward the sensor. Subject to the linkage relationship between the first and second linkages, the distance between the sensor and the sensible member can be changed, thereby generating a relative sensing signal.

The invention relates to a device and to a method for controlling a test stand arrangement having a specimen and having a loading machine, which is connected to the specimen by a connecting shaft. An estimated value (T.sub.E,est) for for the internal torque (T.sub.E) of the specimen is determined and, from the estimated value (T.sub.E,est), while taking into account a natural frequency (f.sub.0) and a delay, a damping signal (T.sub.Damp) is determined and fed back into the control loop.

A superconducting gravitational wave senser includes a toroid-like torque body having first and second diametrically opposed mass objects to provide a bi-pole mass distribution about its Z-axis for torque perturbations by gravitational waves. The torque body includes superconducting material that produces a magnetic field when perturbed; the field indicative a gravitation wave.

A resistance apparatus for exercise equipment includes a resistance adjusting unit and a sensor unit. The resistance adjusting unit includes an adjusting member, a tubular sleeve located above the adjusting member, an adjusting shaft disposed in the tubular sleeve. A first threaded nut is pivotally mounted to the adjusting member and threadedly connected to the adjusting shaft. The sensor unit has a moveable member, a second threaded nut, a first sensing member and a second sending member. One end of the moveable member is pivotally mounted to the adjusting Member. The second threaded nut is threadedly connected to the adjusting shaft and moveable member. The sensing members are disposed on the other end of the adjusting member and the moveable member, respectively. Thereby, a distance between the sensor and the sensing member is changed with respect to the corresponding movements of the first and second threaded nuts on the adjusting member and the moveable member for generating corresponding sensing signals.
