摘要:
A system (100) for directing incident sun light to a receiver (150) based on an integral imager (116) is disclosed. The system includes an imager (116) mounted to a reflector (112); a tracking controller (226) coupled to the imager; and one or more actuators (114) connected to the reflector and tracking controller. The tracking controller (226) is configured to receive and process image data from the imager (116); determine angular positions of a radiation source and target relative to the mirror normal vector (N) based on the image data; and orient the reflector with the axis bisecting the angular positions of the sun and receiver (150). When the optical axis of the imager is precisely aligned with the vector normal to the reflector, the source and target will be detected as antipodal spots (320, 330) with respect to the center of the imager's field of view, which may be used to effectively track the sun or like object.

A method of determining whether a product is within a useable shelf life includes obtaining a first set of data associated with the product, wherein the first set of data includes a first timestamp and a first assessed quality, obtaining a second set of data associated with the product, wherein the second set of data includes a second timestamp and environmental history data, computing a second assessed quality using the first and second timestamps and the environmental history data, and determining whether the product is within the useable shelf life using the second assessed quality.
摘要:
An article merge unit (14) includes a first conveyor for conveying articles (24, 26) in a first stream having a first speed, a second conveyor (32, 34) having a plurality of lateral pushers (46), and a third conveyor (36). The first conveyor conveys the articles in the first stream to the second conveyors where the lateral pushers selectively diverting the articles across the second conveyor to the third conveyor. A control controls the conveying speed of the third conveyor and selectively actuates the lateral pushers to push a selected article from the first and second streams to the third conveyor wherein articles conveyed on the third conveyor are conveyed in a take-away stream having no side-by-side articles and the take-away stream has a greater speed than the first speed.

A solar power plant includes central receiver modules arranged in a regular pattern. Each central receiver module includes a tower, a central receiver mounted on the tower, and a heliostat array bounded by a polygon. The heliostat array includes heliostats with mirrors for reflecting sunlight to the central receiver. The heliostats are grouped in linear rows and each of the rows is parallel to another row. The locations of the heliostats are staggered between adjacent rows. The power plant also includes a power block for aggregating power from the central receivers and power conduits for transferring power from the central receivers to the power block.
