Disclosed herein is a device for measuring root pulling force (RPF) in a plant. The RPF device can comprise a plant grasping mechanism, as well as a force measurement sensor. The device can be automatic, so that the hand of man is not required to exert force on the plant while the root pulling force of the plant is being measured. Also disclosed is a root pulling force motion mechanism, which brings the RPF device into proximity of a plant to be measured. Further disclosed is a method for measuring root pulling force of a plant.

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.

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.

A grip-strength device with detection function comprises: a grip-strength assembly comprising a first supporting piece, a second supporting piece, a rebounding element, a plurality of detection elements, a circuit element, a pull-force measuring element, and a power-supply element. The user can hold the grip-strength assembly and press the first supporting piece and the second supporting piece; and the force given by the user to the first supporting piece and the second supporting piece is measured by the pull-force measuring element; thereby detecting the user's grip force; or touching the detection elements with both hands, the circuit element will generate the detection current to enter the human body through the detection elements and then returns to the circuit element to detect the muscle mass in the human body; thereby the grip-strength assembly can have the functions of simultaneously detecting the grip strength and the body's muscle mass.

A method for determining a sufficient stent removal force includes providing a balloon fastened to a shaft with a stent securely clamped to the balloon. In order to move or remove the balloon from the stent, a stent removal force has to act on the balloon in the axial direction. The stent, which surrounds the balloon, is clamped between first and second holding jaws with a predefined contact pressure perpendicularly to the axial direction. A predefined, desired stent removal force is then exerted on the balloon via the shaft in the axial direction, at which the balloon should not be removed from the stent. If the balloon moves axially relative to the stent, the force is considered to be too low and the shaft-balloon-stent assembly is discarded as a reject. If the stent position remains constant, the stent removal force is considered to be sufficient.

Systems, methods, and apparatus related to a homing mechanism within a drive mechanism of a lacing engine for an automated footwear platform are described. In an example, the homing apparatus can include an indexing wheel, a plurality of Geneva teeth and a stop tooth. The plurality of Geneva teeth can be distributed around a portion of a perimeter of the indexing wheel. Each Geneva tooth of the plurality of Geneva teeth can include side profiles conforming to a first side profile that generates a first force when engaged by an index tooth on a portion of the drive mechanism. The stop tooth can be located along the perimeter of the indexing wheel between two Geneva teeth. Additionally, the stop tooth can include side profiles conforming to a second side profile that generates a second force when engaged by the index tooth.

A force measuring system for exercise equipment provided for using in an exercise equipment, the system includes a measured body, a force sensor, a circuit board; a Wheatstone bridge, a data transmission module and a power module disposed on the circuit board; and a receiving device. The power module provides a working power supply. The measured body is connected to the exercise equipment. The force sensor is disposed on the measured body, and the resistance value thereof changes along with a deformation amount of the measured body. The Wheatstone bridge is electrically connected to the force sensor to output a measurement signal. The data transmission module transmits a force taken information to the receiving device, wherein the force taken information is obtained according to the measurement signal.

A magneto-elastically-based active force sensor, used with a tow coupling between a towed and a towing vehicle or a coupling between a vehicle body and a suspension of the vehicle, which outputs a signal useful for determining forces acting on the coupling. The outputted force information may be provided by processor-enabled embedded software algorithms that take inputs from the force sensor and other sensors, may be used by one or more vehicle systems during operating of the vehicle, such as engine, braking, stability, safety, and informational systems. The force sensor includes directionally-sensitive magnetic field sensing elements inside the sensor, and shielding may be used around the sensors to reduce the influence of external magnetic fields on the sensing elements. The force sensor may be used with different tow and vehicle weight sensing coupling devices installed on different types of automobile cars and trucks.

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.

A test strip for checking a contact pressure of a seal has a checking element. By means of the checking element, the test strip indicates whether the contact pressure is less than or greater than specified contact pressure. The test strip indicates whether the contact pressure lies within a specified range. There preferably two weakening lines for this purpose, which tear at different contact pressures when tension is applied while the test strip is clamped.
