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.

The present invention relates to a method and an arrangement for measuring a force and/or moment on a machine element extending along an axis, using the inverse magnetostrictive effect. The machine element has a magnetization region for magnetization, this region fully encompassing the axis. The arrangement includes at least one first magnetic sensor and one second magnetic sensor, each being designed to measure individually a first and a second direction component of a magnetic field that is caused by the magnetization and by the force and/or the moment. The direction components that can be measured using the first magnetic sensor have differing orientations. Likewise, the direction components that can be measured using the second magnetic sensor have differing orientations. The first magnetic sensor and the second magnetic sensor are arranged around the axis at different peripheral positions.

A manual manipulation apparatus including a frame assembly, at least one handle associated with frame assembly, a mounting structure configured for mounting of a computer device relative to the frame assembly and an optional glide base connected to the frame assembly, the glide base defining an area of reduced friction. The handle can be configured as a grip handle which allows a gripping force to be applied and indicated.

The present invention provides a sensor having an improved sensitivity and precision, which is lighter and more flexible than conventional sensors, and a method of making the sensor. The present invention relates to a sensor comprising a resin foam containing a magnetic filler, and a magnetic sensor that detects a magnetic change caused by a deformation of the resin foam, wherein the resin foam is a polyurethane resin foam that comprises a polyisocyanate component, an active hydrogen component, a catalyst and a foam stabilizer, and wherein the resin foam has a hardness change (H.sub.1-H.sub.60) of 0 to 10 between a JIS-C hardness (H.sub.1) in one second after contact with a pressure surface of a hardness tester and a JIS-C hardness (H.sub.60) in 60 seconds after the contact.

The invention relates to the field of measurement technology using computational technology and can be used in the industrial field that deals with pipelines (e.g., in the oil and gas industry, the construction industry, the energy industry, the nuclear industry, the utilities industry, the diagnostics of metallic structures, and the environmental protection industry). The technical result is an increase in the accuracy of determining mechanical stresses, while simultaneously providing the proper accuracy of detecting an anomaly source in a pipeline.

A strain sensor having an active area that includes a magnetoelastic resonator and spring configured so that the spring undergoes a greater amount of strain than the resonator when the sensor is under load. The sensor is anchored at opposite ends of the active area to a substrate for which strain is to be measured. An interrogating coil is used for wireless sensor readout. A biasing magnet may be included to provide a desired sensor response for the particular application of the sensor. The strain sensor may be implemented as a differential strain sensor that includes a second, strain-independent reference resonator.
