The load cell for measuring a force in both push and pull includes a body assembly having a body element defining a measurement chamber with a closed end and an opposite open end, a protruding member positioned within the measurement chamber and extending from the closed end toward the open end. The load cell also includes a base assembly secured at the open end of the body element, including a base element; and a sense die attached to the base element and aligned with the protruding member, where a top surface of the sense die supports a Wheatstone bridge circuit configured to generate a signal based on a force exerted by the protruding member on the sense die. The body element, the protruding member and the base element are integrally formed from a common material which has a CTE close to the CTE of the sense die.

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.

A multi-link device includes a load tension pin including a sensor configured to measure tension applied to the load tension pin, network interface hardware, one or more processors, and one or more memory modules storing computer readable and executable instructions which, when executed by the one or more processors, cause the multi-link device to: determine whether the tension measured by the load tension pin exceeds a threshold value; and transmit, by the network interface hardware, load event data to a receiver in response to determination that the tension exceeds the threshold value.

Disclosed is a self-powered real-time monitoring system for fluid flushing of an underwater fixed foundation. Said system converts wave energy into electrical energy by means of a wind energy capturing module and a wave energy capturing module, and then uses the electrical energy to supply power to a settlement monitoring module, achieving the reduction of power consumption of the settling monitoring module during the detection of underwater surface settlement at the periphery of a fixed foundation.

The present invention includes a device for determining the force necessary for the separation of a bullet from an ammunition cartridge comprising a chamber housing having central bore extending from a lower housing end to an upper housing end and terminating at a upper aperture, wherein the central bore comprises a chamber diameter adapted to accept an ammunition cartridge and that the bullet partially extends from the upper aperture; a frustaconical shape shoulder in the central bore at the upper housing end to reduce the chamber diameter to mate to an ammunition cartridge shoulder; a neck that connects the upper aperture to the frustaconical shape shoulder adapted to accept an ammunition cartridge neck; a cartridge retention lip within the upper aperture adapted to contact an ammunition cartridge bullet aperture; a chamber mount adapted to connect the chamber housing and a testing device; a bullet securing device comprising a bullet securing end to secure the bullet and a bullet securing device mount adapted to connect to the testing device; a moving mechanism to move the bullet securing device away from the chamber housing; a sensor in communication with the moving mechanism to measure a force exerted by the moving mechanism; and a display in communication with the sensor to display and or record the force.

A wear detection method and system for a linear actuator such as a pneumatic cylinder, a hydraulic cylinder, an electric cylinder or the like. A physical amount detection sensor 9 is mounted on a linear actuator in which a push-pull member connected to a rod 2 pushes and pulls a pressure-receiving object while applying a lateral load in a direction different from the linear movement direction. An external force that is generated between a tube and the mounting member when the pressure-receiving object is pushed and pulled is detected by the physical amount detection sensor 9 and compared with standard external force data, which was detected in a state without abnormalities and stored in a computation/storage/determination processing device 10, to computationally determine whether the linear actuator is in a normal state or an abnormal state.

A hitch force monitoring system includes a hitch ball having a stem downward mountable to a vehicle drawbar. Two or more sensors are attached to the stem to respectively measure longitudinal and lateral forces on the hitch ball. A controller is communicatively coupled to the two or more sensors to receive the measured longitudinal and lateral forces and the user interface. The controller is communicatively coupled to a user interface device to indicate the measured longitudinal and lateral forces on the hitch ball that represent push, pull and sway forces of a trailer load attached to the hitch ball.

A mobile apparatus that is automated to measure controlled and applied forces and moments to sport surfaces allowing for performance and safety assessment of athletic apparel and athletic surfaces, such as natural or artificial turf. The apparatus is capable of using not only shear and compressive forces, but also rotational moments, and all prescribed forces and moments in combination at the same or different times. The apparatus and related system can link these forces and moments together and combine them to more closely mimic behaviors of a human foot during an athletic movement, thereby applying and measuring interactions between all forces and moments at the same or different times.
