An apparatus, a system and a method indirectly detect the operational state of a machine among a plurality of operational states and track the movement of a material through a plurality of machines.

A method of calibrating a yield sensor of a harvesting machine. The yield sensor generates a grain force signal as clean grain piles are thrown by the elevator flights against the sensor surface of the yield sensor. A grain height sensor is disposed to detect a height of the clean grain pile on each passing elevator flight. Each grain height signal is associated with a corresponding grain force signal by applying a time shift to account for a time delay between the time the grain height signal is generated and the time at which the impact signal is generated. The grain force signal is corrected by multiplying the grain force signal by a correction factor. The correction factor is the sum of the grain height signals divided by the sum of the grain force signals over a predetermined period.

A weighing apparatus includes a conveyance unit configured to convey an article, a weighing unit configured to weigh weight of the article conveyed by the conveyance unit, a processing unit configured to process an original signal related to weighing, by a plurality of digital filters set in advance, the original signal being output from the weighing unit, and a display unit configured to display information output from processing unit, in which the processing unit is configured to generate evaluation information for each digital filter to be applied, based on a result of sequentially applying the plurality of digital filters to the original signal that is output when the conveyance unit is in operation and the article is not conveyed by the conveyance unit, and the display unit is configured to display at least one of the evaluation information.

An assembly line grow pod includes a seeding region, a harvesting region, a track that extends between the seeding region and the harvesting region, a cart including a tray for holding plant matter, and a wheel coupled to the tray, where the wheel is engaged with the track, and a weight sensor positioned on the cart or the track, where the weight sensor is positioned to detect a weight of the plant matter positioned within the cart.

Aspects involve controlling application of a coolant, such as liquid nitrogen, to an aggregate on a conveyance system based on detecting the presence of the aggregate on the conveyance system. A sensor, such as a load sensor, may be located on or near the conveyance system upstream from a dispensing system of the coolant. The load sensor may detect the presence of aggregate on the conveyance device and provide an indication of the presence to a controller. The controller may, in turn, control a dispensing system to either apply or prevent application of the coolant onto the aggregate in response to the output of the load sensor. Through controlling of the dispensing system based on detection of the presence of aggregate on the conveyance device, damage to the conveyance device may be avoided or prevented, prolonging the life of the conveyance device.

A conveyor system comprising a conveyor and a conveyor weighing apparatus. The conveyor weighing apparatus has a load determination device for determining the load exerted the conveyor on a conveyor support. The conveyor weighing apparatus may have measurement devices for measuring the angle and speed of the conveyor. The load determination device determines the load exerted by the at least section of conveyor in both laden and unladen states, and the results are combined with the speed and angle measurements, and with known system constants, to calculate the weight of material being conveyed.

A crop elevator for a combine harvester includes an ascending section and a descending section and a housing enclosing the ascending section and the descending section. The elevator further comprises an elevator loop arranged inside the housing which includes a plurality of paddles for elevating a harvested crop. The elevator also includes a weighing system configured to determine a weight of harvested crop that is present on at least one of the paddles during an ascending movement of the at least one of the paddles in the ascending section. The weighing system includes a weight sensor configured to output a weight signal representative of the weight of the harvested crop. The ascending section of the elevator comprises a measurement section, wherein the weighing system is configured to retrieve the weight signal when the at least one of the paddles is in the measurement section of the elevator.
