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.

A trailer coupling for a motor vehicle for attaching a trailer or for supporting a load carrier, including a coupling arm provided for coupling a coupling piece of the trailer or load carrier, and at least one sensor arranged on the coupling arm for detecting a deformation of the coupling arm caused by a load on the coupling arm.

Systems and methods are presented for cancelling noise from sensed magnetostriction-based strain measurements. A drive signal corresponds to a drive coil, and a sensed signal corresponds to a sensed coil. The drive signal is used to at least partially eliminate noise similar to the drive signal from the sensed signal to generate an output signal.

Apparatuses, systems, and associated methods of manufacturing are described that provide for improved sensor devices. An example sensor device includes a magnet mounting tube and a magnet supported within the magnet mounting tube. The sensor device includes a sensor mounting tube that receives at least a portion of the magnet mounting tube and supported magnet therein. The sensor device includes a magnetic sensor affixed to the sensor mounting tube. The sensor device includes a spring positioned around the magnet mounting tube and the sensor mounting tube such that the magnet and the magnetic sensor are surrounded by the spring. In an instance in which a load is applied to either a first end or second end of the spring, the magnet mounting tube translates relative the sensor mounting tube so as to induce a change in magnetic flux identified by the magnetic sensor indicative of a weight of the load.

A load sensor includes a core having a hollow part provided therein and containing magnetic material and a coil attached to the core. A magnetic path along which a magnetic flux generated by a current flowing in the coil is formed along a circumference direction of the hollow part. The core has a load-receiving portion that receives a load at a surface of the core located in a crossing direction crossing a plane along which the magnetic path is formed.

An electromechanical sensor and a method of sensing an object or a tactile input using the sensor. The sensor includes: a base provided with a magnetic sensor arranged to detect a change in magnetic flux at the position of the magnetic sensor; a flexible film adjacent to the magnetic sensor; and a magnetic element provided on the flexible film; wherein the magnetic element is arranged to move relative to the magnetic sensor when the flexible film is reversibly deformed by an external force applied to the flexible film.
