A system for monitoring loading of equipment includes a transmitter assembly mounted to the equipment and a central server. The transmitter assembly has a strain gauge secured to the equipment, an on-board controller and a battery. The central server is in communication with the on-board controller. The central server is configured to receive collected loading data from the transmitter assembly. The on-board controller is configured to operate the transmitter assembly in a load monitoring power mode and a deep sleep mode. The on-board controller is configured to operate at a sleep interval when a load measured by the strain gauge is less than ten percent of a rated working load of the equipment and at an active interval when the load measured by the strain gauge is greater than ten percent of the rated working load. The sleep interval is less than the active interval.

A weighing device includes a weighing module, a processor, and an output device. The weighing module includes a suspension component, a deformation component, and a sensor. The deformation component includes an elastic piece, a connecting portion, and a fixing portion. The elastic piece is coupled between the connecting portion and the fixing portion. The suspension component includes a hook and a lanyard. One end of the lanyard is fixed to the connecting portion, and a second end of the lanyard is passed through the fixing portion and coupled to the hook. When the hook suspends an object to be weighed, the hook moves the connecting portion toward the fixing portion and deforms the elastic piece. The sensor detects a deformation amount of the elastic piece. The processor calculates a weight of the object according to the deformation amount and an elastic coefficient of the elastic piece.

An assistance system uses cameras and sensors to identify a set of vehicle wheels within a lift area, then virtualizes the position and orientation of the vehicle relative to one or more lift posts. The system also determines a center of gravity for the vehicle and uses that center of gravity and other information associated with the vehicle to determine a position within the lift area at which the vehicle should be positioned. The system may also provide guidance to aid in positioning the vehicle at or near that position. Such guidance may be provided as one or more visual or audio indicators or via a software interface. The system may be integrated with lift arms allowing for automated rotation, extension, and elevation of lift adapters once the vehicle is positioned, and it may use distributed processing to locate relevant objects in captured images used in this calculation.

A load cell that is detachable from a suspension belt cable that is subjected to tension resulting from a suspended load; comprising a cell body with a rectangular parallelepiped configuration wherein the length is greater than the width of the cell body; at least one first, second and third protruding tabs projecting from a long longitudinal edge of the cell body and configured to mechanically couple with the suspension belt cable; and at least one strain gauge configured to be positioned above an intermediate zone of a long side of the cell body; such that the first, second and third protruding tabs are evenly distributed along the long longitudinal edge of the cell body and the first and third protruding tabs are positioned in on a distal plane parallel to the long longitudinal edge of the cell body; with the first and third tabs having protrusions that prevent the cell from shifting or coming off of the belt cable.

Methods and systems for estimating an axle load of a vehicle are described. In one example, a method is disclosed wherein axle load is estimated in response to an angle between two components of an axle. The angle may change as weight is added to or removed from the axle such that axle load may be determined as a function of the angle.

Disclosed is an apparatus for emptying bottles containing frozen blood product. The apparatus comprises an automatic unit for checking the weight of emptied bottles. The automatic unit comprises a load detection system for measuring the weight of emptied bottles, an air pressure measuring unit for measuring the pressure in the room in which the emptying apparatus is located, and a measurement compensation unit for correcting the load value on the basis of the room pressure measurement. The weight-checking unit generates a not empty signal if the value of the corrected load is greater than or equal to a predetermined value.
