A system and method for determining the load in a material handling system is disclosed. The load weight detection system measures torque at four operating conditions both at constant speed and during acceleration. The level of torque generated by the motor under each of these operating conditions is stored in the motor drive. The motor drive also receives a signal corresponding to the speed of the hoist motor. Based on the measured torque, as well as the expected torque at no load and at rated load for the measured speed, the motor drive then determines the load present on the hoist. In some systems, two or more hoists are required to operate in tandem to lift a load. Each motor drive determines the weight of the load supported by its respective hoist motor and determines a total weight of the load based on the weights determined by each motor drive.

The disclosure provides a weighing structure and adsorbed gas measuring equipment, and belongs to the field of gas detection. The weighing structure comprises a mounting plate connected with a balance, a plurality of mounting rings and lifting devices, a plurality of mounting holes are formed in the mounting plate, and the upper portions of the mounting rings pass through the mounting holes; the lower portions of the mounting rings are provided with suspension wires for hoisting mounted objects, the mounting holes are in clearance fit with the mounting rings, and the lifting devices provide upward supporting force for the mounting rings. The measuring equipment further comprises a kettle body, and a cavity for accommodating the weighing structure and a support for supporting the balance are arranged in the kettle body, wherein weights or a sample cylinder are/is arranged at the lower ends of the suspension wires, and a heating layer and a gas injection nozzle are arranged outside the kettle body. According to the disclosure, the problem of inaccurate weighing caused by a weighing structure in the prior art is solved.

A non-transitory computer-readable medium includes instructions that when executed by a processor cause the processor to perform a method for providing visual navigation assistance in retail stores, which may include receiving a first indoor location of a user within a retail store; receiving a target destination; and providing first navigation data to the user through a first visual interface. The method may also include, after providing the first navigation data, receiving a second indoor location of the user within the retail store; determining that the second indoor location is within a selected area around the target destination, with the selected area not including the first indoor location; and, in response to the determination that the second indoor location is within the selected area around the target destination, providing second navigation data to the user through a second visual interface, where the second visual interface differs from the first visual interface.

A fluid container measurement system is disclosed. The fluid container measurement system is configured to suspend a load measurement assembly a distance above a support surface. The load measurement assembly houses a load cell and a measurement control circuit. The measurement control circuit is coupled to the load cell and configured to receive electrical signals indicative of a force imposed on the load cell. Electrical signals generated by the load cell indicative of the force exerted on the load cell can be used to measure the fluid container attached to the load cell linkage member.

A system for making gradual adjustments to planograms may include at least one processor. The processor may be programmed to receive a first image of a shelf; analyze the first image to determine a first placement of products on the shelf; determine a planned first adjustment to the first placement of products; and provide first information configured to cause the planned first adjustment. The processor may then receive a second image of the shelf captured after the first information was provided; analyze the second image to determine a second placement of products on the shelf; determine a planned second adjustment to the second placement of products; and provide second information configured to cause the planned second adjustment to the determined second placement of products.

Extracorporeal blood treatment apparatus with reservoir status lights and methods of monitoring reservoir status using the same are described. The extracorporeal blood treatment apparatus include a plurality of reservoir scales (30), each of which is configured to weigh a reservoir (32) used in connection with the extracorporeal blood treatment apparatus.
