A boom assembly for a hoist may include a flat surface configured to elastically deform in response to a load on the hoist, and a strain sensor coupled to the flat surface and configured to generate an electronic signal.

A methods and system to operate hydraulic fracturing units may include utilizing hydraulic fracturing unit profiles. The system may include hydraulic fracturing units may include various components. The components may include an engine and associated local controller and sensors, a transmission connected to the engine, transmission sensors, and a pump connected to the transmission and powered by the engine via the transmission and associated local controller and sensors. A supervisory controller may control the hydraulic fracturing units. The supervisory controller may be in communication with components of each hydraulic fracturing unit. The supervisory controller may include instructions to, for each hydraulic fracturing units, obtain hydraulic fracturing unit parameters, determine a hydraulic fracturing unit health assessment, and build a hydraulic unit profile including the health assessment and parameters. The supervisory controller may, based on the health assessment, determine the hydraulic fracturing unit's capability to be operated at a maximum power output.

The invention relates to a safety link for use in lifting, winching, towing or securing apparatus or similar. The safety link including, a first connection point, a second connection point, and an indicator means positioned substantially between and associated with the first connection point and the second connection point. If an overload force is applied, the forces between the first connection point and the second connection point cause a change in the indicator means, whereby the change indicates the overload to the user so safety checks may be conducted. The invention also relates to a method of use.

A method, apparatus and system for transportation monitoring are provided. The method includes: obtaining force change information of a transportation device detected by a detector; and monitoring, based on the force change information, a quantity of times of transportation that the transportation device loads a transportation object at an initial position, transports the transportation object to a target position, and unloads the transportation object at the target position.

A system that includes a driving component, such as a motor, and a driven component. The system also includes a torque limiter positioned between the driving component and the driven component. The driving component is coupled to a driving end of the torque limiter and the driven component is coupled to a driven end of the torque limiter. The torque limiter is configured to assume a normal operating state with no slippage between the driving and driven ends of the torque limiter and an over-torque operating state with slippage occurring between the driving and driven ends of the torque limiter. The torque limiter includes a metal moving part that assumes a first position when the torque limiter is in the normal operating state and a second position different than the first position when the torque limiter assumes the over-torque operating state. An inductive proximity sensor monitors the position of the metal moving part.

There are disclosed a measuring apparatus and method for measuring the pull-off force of a frangible arrangement connecting a capsule with a tamper evident band of closed annular shape, with an annular ridge that axially retains the tamper evident band, a pusher device that pushes the capsule so as to cause the breakage of the frangible arrangement, a sensor arrangement to detect the tensile force applied by the pusher device, and a lifting and abutting device arranged for supply the capsule to the annular ridge.

There are further disclosed a band disengagement arrangement for disengaging the tamper evident band from the annular ridge after the breakage of the frangible arrangement, yet maintaining intact the closed annular shape of the tamper evident band.

A foot presence sensor system for an active article of footwear can include a sensor housing configured to be disposed at or in an insole of the article, and a controller circuit, disposed within the sensor housing, configured to trigger one or more automated functions of the footwear based on a foot presence indication. In an example, the sensor system includes a capacitive sensor configured to sense changes in a capacitance signal in response to proximity of a body. A dielectric member can be provided between the capacitive sensor and the body to enhance an output signal from the sensor.

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.
