A device for grading aquatic organisms is disclosed. The device includes a pump, a grader, two or more receptacles for receiving aquatic organisms from the grader, a counter, and a control system. The grader comprises a rotating barrel with a plurality of chambers, a bottom part of each of the plurality of chambers having an adjustable slit. The control system is designed to adjust at least one of a rotation rate of the grader or a slit setting of the grader based on information from the counter.

A system for count separation of objects comprises a controller, cameras adapted to detect each individual object in a stream of falling objects such that the controller can count the objects, a first receiving location adapted to directly receive the stream of falling objects, a second receiving location adapted to receive objects diverted from the stream of falling objects or to receive the stream of falling objects when the stream of falling objects is diverted from the first receiving location; a mechanical diverter having (a) a first position to not divert the stream of falling objects from the first receiving location and (b) a second position in to divert the stream of falling objects to the second receiving location, and an air blast diverter adapted (a) to divert specific objects or the stream of falling objects to the second location.

Example implementations relate to generating a performance index of an electrical device. An example implementation includes determining an acoustical contour of a soundscape within a computing enclosure for housing the electrical device. A performance response of the electrical device when subjected to the soundscape within the computing enclosure may be determined. Specifically, a soundscape may be generated within a test chamber that replicates the acoustical contour of the soundscape within the computing enclosure. A performance index of the electrical device may be generated upon being subjected to the generated soundscape.

The present invention relates to systems and methods for monitoring poultry house egg production. The system of the present invention is comprised of the following: a. a conveyor for conveying poultry eggs; b. at least one laser sensor directed in direction of said conveyor for measuring distance of said conveyor's surface and poultry eggs conveyed thereupon; c. a computer coupled with said at least one lase sensor; wherein, number of poultry eggs passed through said conveyor at a given moment is determined by identifying and analyzing fluctuations in measured distance from said at least one laser sensor.
