6604 results about "Load cell" patented technology

A load cell is a type of transducer, specifically a force transducer. It converts a force such as tension, compression, pressure, or torque into an electrical signal that can be measured and standardized. As the force applied to the load cell increases, the electrical signal changes proportionally. The most common types of load cell used are hydraulic, pneumatic, and strain gauge.

System load testing coordination over a network

A method and system using one or more load cells coordinates load testing of one or more sites under test over a network such as the Internet in accordance with one or more load test requests. In one embodiment, such method and system facilitates an economic, efficient, and accurate evaluation of the capacity of the SUTs to support concurrent users of the SUTs. A load test request is received from a User and provides information concerning a load test to be performed on a site under test (SUT). A load test is generated, and the load test is allocated to one or more load cells. The load cells perform the load test by sending load test data to the SUT and receiving responses from the SUT. Portions of a load test may be allocated to different load cells, which may be geographically remote from the SUT and / or geographically diverse. Multiple concurrent pending load tests may be processed for the same SUT. A load cell may concurrently perform all or a portion of multiple different load tests for multiple different SUT's simultaneously. A reporting function generates a report based on the responses received from the SUT. The reporting function may in addition or alternatively allow the User to view real-time results during load test execution.

An apparatus for preventing occupant injury during accident has various features to ensure safety. A sensor 70, detecting seat belt engagement is provided. In addition, there is a means for varying the tension of a seatbelt 17, depending upon the weight of the occupant 110 and the speed of the vehicle carrying the occupant 110. When the occupant 110 seats on any of the seats 17, the load cell switch 18 will close, allowing the load cell output energy to energize the control module 25. The control module 25 will then enables the counter 50 to count the number of closed load cell switches 18. The control module 25 further enables an optoisolator switch configured with the sensor 70 to then energize a latching relay 80 operatively configured to check the seat belt latching of all occupied seats 10 with closed load cell switches 18, to assure occupants safety. The load cells are configured with strain gauges and temperature sensors to ensure human occupants. Such that, when the switch 18 for the occupied seat 10 is closed, the latching relay 80 circuit is energized so that the seat belt 17 for the occupied seat location is checked for buckling. The latching relay 80 circuit and the counter 50 circuit are operatively configured and closed only when an occupant 110 takes any of the seats 10. The latching relay switch 85 is only energized when the counter circuit 50 is closed.

Down Pressure Adjustment Device And Method For Use With A Disc Opener Assembly Of An Agricultural Implement

A disc opener unit for an agricultural implement has a down pressure adjustment device that automatically adjusts the amount of down pressure applied on a furrowing disc based on strain measurements taken by a strain gauge or load cell. The strain gauge, which may be mounted to an arm that is used to set the position of a depth setting gauge wheel, provides feedback to a processor that in turn controls the amount of hydraulic fluid in a hydraulic cylinder to adjust the down force applied on the disc. The amount of down pressure is therefore adjusted in substantially real-time in response to changes in field conditions, which improves furrow depth consistency and reduces wear on the gauge wheel and its components.

Weight sensors having centralized loose tolerance universal force and Mx/My moments overload stops

Automotive load cells having centralized, multi-axis, loose tolerance overload / limit stops provide improved strain gauge response. The modular, integrated stop assemblies magnify sensor substrate deflection by use of opposed concave (Belleville) springs are used in direct contact with the substrate to accommodate ±Z axis deflection and Mx / My moment angular rotation. A flanged guide member on the load stud permits a wide range of geometries. The substrate is thickened around the load stud hole and the outboard support bolt holes. Hollow rivets assist in design modularity. Strain gauges are placed at the yield zones symmetrically with respect to the X axis. The substrate hole Mx / My gap is larger than the stop bracket hole to insure a positive stop for Mx / My moments prior to yield. The inventive multi-axis stop assembly is used in any type load cell, including rectangular, thinned, notched, necked / dogbone, or cantilever substrates with any strain gauge layout configuration.

Electronic trigger pull gauge

A gauge for measuring the force required to discharge a firearm by pulling its trigger includes a housing and a rod including a trigger hook portion at a distal end thereof for engaging the trigger. A load cell is connected to the housing and to a proximal end of the rod such that the load cell generates an electrical signal in response to forces on the rod as the housing is pulled while the trigger hook portion is engaged with the trigger. The magnitude of the electrical signal is proportional to the forces on the rod. A microcontroller receives the electrical signal and calculates a force value based thereon. The microcontroller also continuously monitors the forces on the rod and identifies a trigger pull value of the firearm as being the maximum force on the rod until pulling on the housing is ceased once the trigger of firearm has released.

Axle weight distribution system

The present invention relates to a system for adjusting weight distribution throughout all axle groups of the truck and trailer. The trailer has at least one axle group mounted on a pair of rails attached to the frame of the trailer. These axle groups are locked in position on the rails by locking pins. The system for adjusting weight distribution according to the present invention measures the weight on every axle group on the truck and trailer. The measurement may be of weight directly by load cells etc. or indirectly, by taking measurements from the air suspension system to calculate weight. The measurements are delivered as an electrical signal to one or more microprocessors capable of receiving the electrical signals and calculating the optimum position of the axle group on the trailer. The position of the trailer axle groups relative to the rails is also determined and the position delivered to the microprocessor(s). The microprocessor(s) is programmed to calculate the weight on each axle group and determine any change in position of the trailer axle group(s) on the rails to optimize the weight distribution. The information is presented to the driver on a display located in the cab of the truck. The system further includes apparatus to lock and unlock the locking pins that lock the trailer axle group(s) in position on the rails. The system also includes a communication interface between the truck and the trailer.
