    摘要： A rapid diagnostic test system or process uses a single-use module that includes a photodetector. The photodetector generates an electrical signal representing a measurement of light from a test region on a medium such as a lateral-flow strip for a binding assay. For light measurement, the test medium can contain a labeling substance that attaches a persistent fluorescent structure such as a quantum dot to a target analyte, so that the photodetector measures fluorescent light. Multiple photodetectors and an optical system that separates or filters light of wavelengths corresponding to different fluorescent labeling substances allow simultaneous testing for multiple analytes. The single-use module can include a display or LED for visual indication of test results, or the electrical signal can be output for processing in a reusable module.

    摘要： A laser level includes a pair of level units arranged side by side and disposed in different oriented directions. Each laser level includes a laser light source adapted to emit a laser beam, a beam splitter adapted to simultaneously split the beam into first and second light beams along perpendicular first and second directions, and a first and a second aspheric-cylindrical lenses respectively arranged in the first and the second directions. The first and the second aspheric-cylindrical lenses have two optical axes respectively extending along the first and second directions.

    摘要： A clustering and recommendation machine determines that an item is included in a cluster of items. The machine accesses item data descriptive of the item. The machine accesses a vector that represents the cluster and calculates the likelihood that the item is included in the cluster, based on the item variable and the probability parameter. The machine determines that the item is included in the cluster, based on the likelihood. The machine also recommends an item to a potential buyer. The machine accesses behavior data that represents a first event type pertinent to a first cluster of items. The machine calculates a probability that a second event type pertaining to a second cluster of items will co-occur with the first event type. The machine identifies an item from the second cluster to be recommended and presents a recommendation of the item to the potential buyer.

    摘要： An optics system is provided that is made up of a single diffractive optical element that performs beam collimating, beam splitting, and light blocking functions. The diffractive optical element is made up of a substrate having a first surface comprising an entrance facet and a second surface comprising an exit facet. The first surface comprising the entrance facet performs at least the functions of collimating the beam of light produced by the light source and of tilting the collimated beam in a particular direction. The second surface comprising the exit facet performs at least the functions of splitting the tilted collimated beam into at least two collimated light beams and of blocking unintended light (i.e., one or more mode order groups that are not intended to be used for imaging purposes). By performing all of these functions on different surfaces of a single substrate, an extremely compact optics system having very high optical efficiency and a very high signal-to-noise ratio is realized.

    摘要： An optical backplane is provided that has at least first and second side walls that are generally parallel to one another and at least one optical relay element disposed on at least one of the parallel side walls. An optical signal is coupled into the optical backplane through an entrance facet of the backplane. The optical signal is maintained within the optical backplane by internal reflection at the parallel side walls of the backplane. The optical relay element receives the optical signal reflected off of one of the side walls and reflects and refocuses the optical signal to guide the optical signal and prevent it from diverging as it propagates through the backplane from the entrance facet to the exit facet.
