A data display method of a test instrument for a rivet nut setting tool is disclosed. When the rivet nut setting tool is operated, a value of a pull force detected by the pull-force detector is transmitted to the first display area through a circuit module, and a first display area displays variation of the value of the detected pull force in waveform, and the first display area also displays an upper-limit waveform value, a waveform data unit, a current value and a historical maximum value; when the rivet nut setting tool is operated continuously, the first display area displays a continuous waveform, and the second display area displays historical data and average values of maximum pull force values.

A device for testing at least one plug-in element includes a plug-in element receptacle and a test element receptacle, which are adapted to be movable along a test axis for establishing a plug-in connection. A force sensor is configured and disposed to detect a force along the test axis when the plug-in connection is established. A compensating element is configured and disposed for compensating for an offset between the plug-in element and a test element. The compensating element is configured to be at least partially elastic so that the test element is elastically movable to compensate for alignment deviations from the test axis. A method for testing at least one plug-in element is provided along with a method for producing the compensating element.

In an aspect, the present disclosure describes a method comprising using at least one robot to fully autonomously position and assemble at least one solar module and its supporting structure at a sensed geolocation without aid from a user.

The invention relates to a system for protecting a sensor for a force measurement comprising: a force measurement sensor (1), designed to measure at least one tractive force or one compressive force exerted along a longitudinal axis (X) of the sensor, said sensor being designed to be made integral with a moveable part of a fluid reservoir, and a pre-strained elastic element (2) arranged to bias the force sensor (1) in a direction opposite to said exerted force, said elastic element being deformable in the direction of the exerted force so as to protect the sensor from at least one compressive or tractive force greater than a threshold.

The present disclosure provides a method for strength measurement, including: obtaining action information at one or more rounds corresponding to one or more rounds of test actions completed by a user to be tested on a strength-type intelligent fitness device; and updating a measurement parameter of the strength-type intelligent fitness device based on the action information at the one or more rounds. The method further comprises determining a next round of a test action based on the updated measurement parameter; and calculating and obtaining maximum strength information of the user to be tested based on the action information during N rounds of the test actions.

An example smart antenna mount may couple an antenna alignment device with an antenna. The smart antenna mount may include sensors such as strain gauges and accelerometers, and an electronic circuitry to communicate the measurements from the sensors. The measurements are received by the antenna alignment device, which may perform further operations to determine whether the coupling is within desired bounds. If within desired bounds, the antenna alignment device may generate an indication of a normal coupling, e.g., by activating a first colored (e.g., green) LED. If the coupling is outside the desired bounds, the antenna alignment device may indicate an alarm condition, e.g., activating a second colored (e.g., red) LED or generating an audible signal.

Systems and methods of wheelchair systems enabling fine manual motion control are disclosed. In one embodiment, a wheelchair system includes a wheelchair. The wheelchair includes one or more wheels, at least one actuator coupled to the one or more wheels, a processing device, and a non-transitory, processor-readable storage medium in communication with the processing device. The non-transitory, processor-readable storage medium includes one or more programming instructions that, when executed, cause the processing device to determine a wheel torque on the one or more wheels, determine a compensation value, and actuate the at least one actuator applying the compensation value to the one or more wheels to remove at least a portion of the wheel torque such that less external force is required to physically move the powered wheelchair than when the compensation value is not applied.

A tension measuring device for a holding mechanism such as a ratchet or tie down strap. In one embodiment, a tension measuring device comprises a two-part frame, comprising a movable frame part and a stationary frame part. The movable frame part comprises a first connection portion, one or more biasing element rods, a biasing element lock plate with indicator needle, and one or more rod bolt caps. The stationary frame part comprises a second connection portion, a biasing element chamber, and one or more biasing element rod apertures. Further, the tension measuring device comprises one or more biasing elements and a housing.

A method and apparatus for measuring the cutting force on a single fiber. The method includes the steps of: providing a blade having an edge; providing a fiber mount for holding the single fiber; providing at least one sensor connected to the fiber mount; providing a fiber sleeve to contain a fiber within the fiber mount to simulate the location of the hair within the hair follicle; moving the blade toward the fiber and cutting the fiber; and measuring the cutting force on the fiber with the at least one sensor.

The invention relates to a load detection unit having a spring-elastic load carrier assembly for receiving the load (10) and a sensor (3) for the deformation of the load carrier assembly, which occurs under the load (10) that is to be detected, wherein a deformation transmission unit (6) is operatively arranged between the load carrier assembly and the sensor (3). A method, in which additionally a deformation transmission unit is used, is thus provided, which during operation picks up the deformation of the load carrier assembly and transmits it to the sensor as a changed force/path load.
