An inventory management system includes a floor-based weighing subsystem and a load status subsystem. The floor-based weighing subsystem includes a sensor arrangement that includes at least one weight sensor functionally associated with a load carrying unit that supports a load having an associated weight. The load carrying unit is deployed at the floor of a retail display area, and the weight sensor determines the weight of the load. A load status determination engine of the load status subsystem receives, from the floor-based weighing subsystem, the weight of the load determined by the weight sensor, and determines a loading status of the load carrying unit based on the received weight of the load.

A testing apparatus includes a base structure and a supporting structure rotatably coupled to the base structure. The supporting structure includes an engaging portion configured to engage a liquid-retaining article. A load cell assembly connects the base structure to the supporting structure. The load cell assembly includes a load cell configured to measure a reaction force present between the base structure and the supporting structure resulting from an imbalance of the supporting structure about an axis of rotation thereof. The reaction force corresponds to a weight of liquid that has accumulated on the liquid-retaining article following a balancing of the supporting structure about the axis of rotation thereof.

Several embodiments include a method of computing a phase composition ratio of a two-phase mixture in a pipe. For example, the phase composition ratio is a void fraction or a dryness fraction. The two-phase mixture can have one or more material substances that do not travel as a whole (e.g., at least two of solid phase, liquid phase, and gaseous phase or two liquid materials of different densities that do not mix). A load cell can measure, continuously, weight of the pipe and content of the pipe. Then, a computing system or a circuit can compute, continuously, a moving average of the continuously measured weight. The computing system or the circuit can compute a change in the phase composition ratio of the two-phase mixture based on the computed moving average.

An automatic method for thermogravimetric analysis of multiple samples of coal or coke for volatile matter in a thermogravimetric analyzer of the type including an auto-loading delivery system, a furnace, a movable platform within said furnace, an external balance and an internal balance for measuring the weights of sample holders, lids and samples before and after treatment in the furnace. Coal or coke samples are placed in the sample holders and weighed in the external balance and are auto-loaded into the furnace at 950 C. All sample holders are weighed sequentially on the internal balance at exactly 7 minutes from introduction time with space time 14-20 seconds in between them and the weight of the sample holder prior to being placed in the furnace is compared with the weight of the sample holder after it has been treated in the furnace to determine the amount of volatile material.

Provided are non-exposure supplied fuel quantity testing device and method of a vehicle-mounted type, and more particularly, a device formed in a trunk of a vehicle without being exposed to test whether or not the ordered fuel quantity is supplied at the time of supplying fuel. Since the device is formed so as not to be exposed, it is disable to perform an artificial tampering of a lubricator, and since the device is mounted in the trunk, it is enable to measure whether or not the ordered fuel is supplied accurately at the same time as supplying fuel. The present invention relates to a testing method using the testing device.
