Abstract: The invention pertains to a weighing device for determining the weight of discrete weighing products in a speed-independent manner, wherein a weighing chute comprising a sliding surface that is inclined with respect to the horizontal is fed detached weighing products, and the load introduction direction of a weighing cell supporting the weighing chute is aligned perpendicularly to the sliding surface.

Abstract: A storage system for material containers provides a readable ID distinguishing each container, and includes a scale that weighs containers, so that the system can distinguish between containers that are sufficiently loaded to be effective and containers that are insufficiently loaded. The system preferably includes storage for containers held in contact with readers of the container IDs. This allows a controller to keep track of containers checked out for use and returned for storage, and to identify containers that have been discharged.

Abstract: A patient support apparatus includes load cells and a controller operable to automatically update a weight offset for use in determining a true patient weight. The controller is configured to receive signals produced by the load cells, determine whether a patient is being supported by a patient support surface of the patient support apparatus, detect movement on the patient support surface, determine a weight of the patient being supported on the patient support surface, determine whether a patient is no longer being supported by the patient support surface, and update a weight offset.

Abstract: A system and method of calculating chemical usage during a refilling of a supply tank, which includes the steps of providing a chemical system having a first supply tank of known capacity, wherein the tank is mounted upon an electronic scale. The scale is capable of generating a series of signals related to the weight of the tank when empty and at various levels of fill. A system controller receives a series of signals from the scale relating to the weight of the tank when empty and at various levels of fill. The first supply tank is filled from a source of chemical feed and the fill time for the filling of the first supply tank is obtained. The system controller inputs the series of signals from the scale relating to the weight of the tank when empty and at various levels of fill and calculates a usage during refilling based on a feed rate times the fill time.

Abstract: An electronic coupled-in-motion railroad track scale is disclosed and comprises four track logic switches for detecting forward or backward train axle movement, a programmable digital voltmeter connected to load cells for effecting the weighing of the train cars, and a computer (CPU) for controlling the voltmeter as well as the track logic switches, and for correlating the axle numbers to the weight determined for each particular car. The four track switches are situated such that two switches are located in close proximity on either end of the weighbridge and the train track interface. Together with the logic circuits, the switches indicate when an axle comes on or goes off the weighbridge, and in which direction the axle is moving. In this manner, if reweighing is desired, the train may be backed up or forwarded to the particular car in question without reweighing the entire train.

Abstract: The supply of cryogenic fluid used for controlled storage environment of biological materials is monitored so as to insure an adequate level. The monitoring is effected by employing a beam balance mechanism. Counterweights associated with the beam balance are adjusted for providing a balance arm transition around a horizontal axis when the total weight of the container including the biological materials and the cryogenic refrigerant has dropped below a predetermined threshold. A sensing switch associated with the arm of the beam balance actuates an alarm circuit when the weight threshold has been passed.
