An impact torque generator for a hydraulic torque wrench includes a liner, a main shaft, a first drivable blade and a second drivable blade. The liner has two sealing surfaces defined at a position of 180 degree rotational symmetry. For each of the first drivable blade and the second drivable blade, a first sealing surface of the drivable blade is configured to be in contact with one of the sealing surfaces of the liner while a second sealing surface of the drivable blade slides in contact with an inner peripheral surface of the liner so as to create a seal such that a portion of an interior of the liner is divided into a high-pressure chamber and a low-pressure chamber so as to generate impact torque on the main shaft.

A fifth wheel system includes a fifth wheel configured to couple to a kingpin of a towed trailer such that vibrations are generated when the fifth wheel couples to the kingpin. A sensor in operative association with the fifth wheel and configured to sense the vibrations and generates vibration data. A controller receives the vibration data and processes the vibration data to detect a presence or an absence of a predetermined vibration component that occurs when the fifth wheel properly couples to the kingpin. An indicator indicates proper coupling of the fifth wheel to the kingpin when the predetermined vibration component is present.

An improved impact structure comprising a transmission shaft, an impact disc, a driving disc, an output shaft and an impact spring, wherein the driving disc is cylindrical, a lower surface of the driving disc is provided with two V-shaped first inclined surfaces arranged symmetrically. Two V-shaped second inclined surfaces matched with the first inclined surfaces are symmetrically arranged in the middle hole of the impact disc. An output end of the transmission shaft penetrates through the impact disc and is movably connected to the output shaft. One end of the output shaft and an upper end surface of the impact disc are circumferentially provided with a first and a second impact block. One end of the impact spring extends into the inner cavity of the impact disc. Through adopting the present disclosure, the transmission shaft without V-shaped grooves has a higher strength, and qualification rate is significantly improved.

A method for operating an input device. An input element of the input device is manually operated to perform an input into a computer device operatively connected to the input device. Mobility of the input element can be selectively delayed, blocked, and enabled by a controllable magneto-rheological braking device. The mobility of the input element is selectively adjusted by the computer device at least as a function of at least one input condition stored in the computer device. The input device may be a computer mouse.
