A system for performing the inspection of a concrete block includes a conveyor, a weighing module and a scanning module. The conveyor extends along a conveying axis and conveys a support plate with the concrete block supported thereon. The weighing module weighs the support plate with the concrete block supported thereon. The scanning module includes a scanner scanning the upper surface of the concrete block and the upper surface of the support plate. The scanner is displaceable along a scanning axis and has a scanning range covering an entirety of an upper surface of the concrete block supported on the support plate and a section of the upper surface of the support plate extending from at least two consecutive lower edges of the concrete block supported on the support plate. A method performs the inspection of a concrete block.

A load verification system and method may be used to assess the loading of material from a loading work vehicle having a load bucket to a haulage work vehicle having a load bin. The system includes at least one volume sensor coupled to the loading work vehicle that observes a volume of material in at least one of the load bucket and the load bin and generates a corresponding volume data signal. The system also includes a first controller onboard the loading work vehicle and a second controller onboard the haulage work vehicle. At least one of the first and second controllers: receives the volume data signal from the at least one volume sensor; receives a unique haulage work vehicle identifier; associates volume data of the corresponding volume data signal with the unique haulage work vehicle identifier; and stores in memory the associated volume data and haulage work vehicle identifier.

A method of estimating an electrode density in secondary batteries according to one or more embodiments of the present disclosure includes: preparing an electrode comprising a current collector and first and second coating layers coated on the current collector; measuring first characteristic values of the electrode; removing the first coating layer of the electrode; measuring second characteristic values of the electrode from which the first coating layer has been removed; removing the second coating layer of the electrode from which the first coating layer has been removed; measuring third characteristic values of the electrode from which the first and second coating layer have been removed; and estimating at least one of a density of the first or second coating layer, a thickness of the current collector, or a weight of the current collector, based on the first characteristic values, the second characteristic values, and the third characteristic values.
