    摘要： A transparent waveguide, for use in tracking an eye illuminated by infrared light, includes an input-coupler and an output-coupler. The input-coupler includes a stack of electronically switchable diffractive gratings arranged parallel to one another, each of which has a respective lens power that causes each of the gratings in the stack to have a different focal length. Each grating, when turned on, couples received infrared light into the waveguide. A sensor images an eye in dependence on infrared light beams that exit the waveguide at the output-coupler. Images of an eye, obtained using the sensor, are analyzed to determine which one of the electronically switchable diffractive gratings, when turned on, provides a best focused image of the eye or portion thereof. The one of the electronically switchable diffractive gratings, which provides the best focused image of the eye, is used for imaging the eye during eye tracking.

    摘要： A transparent waveguide, which is for use in tracking an eye that is illuminated by infrared light having an infrared wavelength, includes a volume Bragg grating type of input-coupler adapted to receive infrared light having the infrared wavelength and couple the received infrared light into the waveguide. The volume Bragg grating includes a lower boundary and an upper boundary that is closer to the output-coupler than the lower boundary. A k-vector angle of the volume Bragg grating at the lower boundary is greater than a k-vector angle at the upper boundary, with k-vector angles of the volume Bragg grating between the lower and upper boundaries gradually decreasing as distances decrease between grating planes of the volume Bragg grating and the upper boundary. Additionally, the volume Bragg grating preferably has an angular bandwidth that is no greater than 5 degrees.

    摘要： A system for detecting a position of an object such as a surgical tool in an image guidance system includes a camera system with a detection array for detecting visible light a processor arranged to analyze the output from the array. Each object to be detected carries a single marker with a pattern of contrasted areas of light and dark intersecting at a specific single feature point thereon. The pattern includes components arranged in an array around the specific location arranged such that the processor is able to detect an angle of rotation of the pattern around the location and which are different from other markers of the system such that the processor is able to distinguish each marker from the other markers.

    摘要： A classroom response system is disclosed, comprising a classroom response system (CRS) server, at least one instructor console, and at least one student console. The CRS server includes a plurality of software modules, including a runtime server, a master server, a simulator, a query editor, a report generator, a report editor, a seating chart tool, and a simulator. An optional secondary instructor console may be provided, for example for use by a instructor's assistant. In use, the instructor may use the CRS to keep track of attendance, pose questions to students, and receive answers, including open-ended answers. Students may also be allowed to evaluate one another's work. The instructor may display aggregated answers and other anonymous data.

    摘要： An interlocking fence system is disclosed. Two spaced-apart upright posts (8, 10) attached to a grade G support a locking rail 4 with an offset locking aperture 26 and an alignment aperture 32 and further support an alignment rail 6 with an alignment aperture 40. A picket 2 has a locking slot 22 with an edge 28 of the locking aperture 26 in locking rail 4 serving as a tab to restrict axial movement when inserted therein. Alignment aperture 32 in the locking rail 4 and alignment aperture 40 in alignment rail 6 serve to restrict lateral movement of the picket 2. To support the rails (4, 6), retaining slots (24, 24′) in the locking rail 4 and retaining slots (42, 42′) in the alignment rail 6 can be retained by an edge (38, 50, 38′, 50′) in support apertures (12, 14, 16, 18) in the posts (8A, 10A).
