A measurement method includes: a step of acquiring first observation point information including a time point when each part of a moving object passes a first observation point and a physical quantity which is a response to an action; a step of acquiring second observation point information including a time point when the each part passes a second observation point and a physical quantity which is a response to an action; a step of calculating a deflection waveform of a structure generated by the each part; a step of adding the deflection waveforms to calculate a moving object deflection waveform, and calculating a path deflection waveform based on the moving object deflection waveform; a step of calculating a displacement waveform by twice integrating an acceleration of a third observation point; and a step of calculating, based on the path deflection waveform, a value of each coefficient of a polynomial approximating an integration error, and correcting the displacement waveform based on the value of each coefficient.

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.

A robot scheduling method. A robot comprises a cleaning robot for performing cleaning operations in a cleaning area, and a conveying robot for transporting the cleaning robot in an aisle area. The robot scheduling method comprises a task generating step, a task issuing step, a route planning step, a travel controlling step, and a conveying controlling step.

An electronic measurement device or electronic scale including an arrangement of multiple low-cost sensors to measure a physical property of an object is disclosed. The electronic measurement device or electronic scale utilizes an accurate and effective calibration method that compensates for the idiosyncrasies of using individual sensors. The electronic measurement device positions a plurality of sensors at predetermined observational locations to provide sensor output signals in response to sensing physical characteristics of the physical property of the object to be measured and combines the different sensor output signals by applying a combined calibration transfer function that represents a calibration function for each of the plurality of sensors to provide a cumulative measurement signal that represents the measurement of the physical property of the object.

The application discloses a method, system and related device of implementing vehicle automatically weighing, so as to achieve the automatically weighing of the unmanned vehicle. The method includes: controlling, by a vehicle controller, a vehicle to drive automatically and stop at a weighing position; weighing, by a weighbridge sensor, the vehicle when sensing the vehicle stopping at the weighing position, and sending weighing end information to the vehicle controller; and controlling, by the vehicle controller, the vehicle to start and leave the weighing position when receiving the weighing end information.

A system includes one or more processors located remote from a plurality of containers configured to store recyclable material. The one or more processors are configured to receive image data generated by an imaging device positioned to have a field of view of an interior of a first container of the containers. The image data depicts the recyclable material within the first container. The one or more processors receive one or more weight measurements of the first container with the recyclable material therein and determine one or more characteristics of the recyclable material within the first container based on at least one of the image data or the one or more weight measurements. The one or more processors schedule a pickup date for the first container based on the one or more characteristics of the recyclable material that are determined.

Embodiments of the present invention are directed to a new and improved system and method for determining a weight rating for a surface road transporter by using a computing system and digital camera to identify various attributes of the transporter and then, based on those attributes, to determine a maximum allowable load limit for that transporter in a given jurisdiction. In addition, embodiments of the present invention may include a digital optical device and related software configured to scan and decipher a QR code printed on an “overweight” permit issued by a local jurisdiction, where the overweight permit authorizes a specific transporter to carry a load that exceeds its normal gross allowable weight by a specified amount or percentage. Embodiments of the present invention may incorporate the specified overage amount or percentage in its determination of the gross allowable weight rating for that transporter.

A cast load cell comprising a load sensing portion integrally cast with a first mounting portion. The load sensing portion has a flexure portion spaced apart from the first mounting portion by a flexure gap. The load sensing portion has at least one sensor cavity above at least a portion of the flexure gap. A second mounting portion is integrally cast with the load sensing portion above the flexure gap. A load sensor is connected to the load sensor portion and positioned within the sensor cavity above a portion of the flexure gap. The first mounting portion, the load sensing portion, and the second mounting portion define an integral, low-profile, weld-free, substantially homogenous unitary cast member.

Provided is a jack stand that includes a base and a post for extending from the base. A top is provided for topping the post and engaging with a load. The top includes a load spreader for spreading the weight of the load to the post. Advantageously, the spreader spreads the weight of the load to the post thereby resulting in a more heavy duty jack-stand, rated for significantly higher loads, than prior jack stands which instead can fracture under heavy unbalanced loads locally travelling along one side when the loading is not evenly spread.
