An illustrative device capable of detecting a bearing force includes a support rigid by tension and at least one plate that is elastically deformable by the bearing force from a bent conformation in which the plate exhibits a convex bearing face on which the bearing force to be detected is directly exerted and to a more flattened conformation in which the convex bearing face is more flattened. The illustrative device further includes a spring capable of permanently straining the plate to its bent conformation, a guiding mechanism mounted on the support and capable of guiding the free distal end of the plate in translation along a translation axis at right angles to the direction of indentation, and a sensor capable of detecting a displacement of the free distal end along the translation axis to detect the bearing force.

A variety of applications can include apparatus and/or methods that provide an axial force transducer. Two coils wound coaxially with respect to each other can be used with a magnet to determine a distance traveled based on application of an axial force to an instrument component. The two coils and magnet can be configured in a number of ways with respect to the instrument component. In various embodiments, the difference between an inductance associated with one of the two coils along with its relation to the magnet and an inductance associated with the other one of the two coils along with its relation to the magnet can be used to determine the axial force on the component of the instrument associated with the distance travelled. Additional apparatus, systems, and methods are disclosed.

A pressure sensing device comprises a first diaphragm which is deformable and a second diaphragm which is non-deformable. One of the diaphragms comprises a pressure sensitive material arranged on its surface. The other diaphragm comprises a detection electrode arranged its surface. The first diaphragm forms part of a force transmission device comprising a cavity having a force transmission fluid therein. The force transmission device is configured to receive an external force and transmit the external force to the first diaphragm, such that the first and second diaphragms are mutually deformed in response to the external force.

An apparatus (20) for monitoring flotation performance apparatus comprises an arm (21) having a paddle (22) attached at one end. The apparatus (20) forms a sensor to monitor real-time flotation performance by measuring the drag exerted by the overflowing froth onto a cantilever beam arm. The strain exerted on the beam or arm can be directly correlated to the efficiency of the froth flotation process. Methods for monitoring and controlling a froth flotation process and a method to determine ash content in coal undergoing flotation are also described

A method of controlling a force sensor system to define at least one button implemented by at least one force sensor, the method comprising: receiving a force sensor input; determining a gradient of the force sensor input; and controlling the force sensor system based on the determined gradient.

An active stylus including a pen housing, a pen core module disposed in the pen housing, a control module disposed in the pen housing, and an elastic member assembled to the control module and the pen core module is provided. The pen core module has a first end and a second end opposite to each other. The first end is protruded out of the pen housing. The control module has a force sensing element, and an elastic force of the elastic member drives the second end of the pen core module to be abutted to the force sensing element seamlessly.

The invention relates to a method for monitoring operating parameters of an actuator (10), wherein the method comprises: providing the actuator (10), providing at least two detection units (26, 28, 30, 32, 34, 36) which are designed to detect different operating parameters of the actuator (10), detecting operating parameters of the actuator (10) via the detection units (26, 28, 30, 32, 34, 36), outputting data relating to the measured operating parameters to an evaluation unit, combining the measured operating parameters into a state information, which indicates whether or not the technical state of the actuator (10) is in a predetermined standard state.

Systems for force measurement upon orthodontic appliances are described. Generally, a system for measuring a force or moment imparted by an orthodontic appliance may comprise a dentition mold having one or more target teeth each formed upon a fixture and which is movable independently of the dentition mold, a measurement sensor coupled to the fixture, and a processor in communication with the measurement sensor. An orthodontic appliance may be configured for placement upon the dentition mold where the orthodontic appliance imparts a force or moment upon the one or more target teeth such that the force or moment is transmitted to the measurement sensor via the fixture for measurement of the force or moment.

A method checks a plug connection, in which a first plug part is connected to a second plug part. The method determines a force-time curve of a force applied by an assembler during an assembly process of a plug connection. In addition, the method determines characteristic values of a plurality of characteristics of the force-time curve. The method also classifies the plug connection by use of a machine-learned classifier on the basis of the characteristic values of the plurality of characteristics.
