    Abstract: A video interface linking a base station with a remote display, e.g., a head-mounted display, converts input video signals from NTSC or PAL formats into modulated video signals containing repetitive sequences of frame times with embedded audio and control signals. Each frame time includes equal consecutive color field times. Frame rates are converted by inserting selected repeating color frames into the datastream. Bursts of image information occupy a portion of each field time. During each data burst, the display is loaded with pixel luminance data. Between bursts, the display is illuminated by a color LED. Two video displays can be driven alternately, i.e., the first display loads while the second is illuminated. The modulated video signal can travel through the atmosphere on an infrared (IR) beam with a wavelength between 700 nm and 1100 nm. In one embodiment, the beam is scattered from a diffuse reflecting surface. Alternatively, the beam is shaped by a shaping lens. Designs for shaping lenses and collecting lens assemblies are described. Some embodiments include return audio transmission.

    Abstract: A diagnostics apparatus for detecting fluorescence events related to the presence of an analyte in a sample is disclosed. The apparatus includes a housing, a source of excitation light and a photodetector, and a unitary multi-surface optical module. The optical module is integrally formed and composed of an upstream portion having a focusing optical surface for directing excitation light from the light source to a focal region within an analyte-detection zone in the apparatus, and a downstream portion having a second focusing powered optical surface and at least one reflecting surface for directing fluorescence-emission light produced by fluorescence events within the detection zone, in a direction substantially normal to the path of the excitation light onto the photodetector. The optical module is adaptable to a variety of assay formats, including multiple-sample, sample-array, and disposable-cartridge formats.

    Abstract: Low-cost complex plastic optics allow biocular viewing of video images generated by a single electro-optic display device, such as in a head-mounted display (HMD) for commercial or medical viewing applications. A dual off-axis configuration uses nearly collimated illumination optics and intermediate imaging optics to fill both eyepieces from a single display device without the need for a beamsplitter. Multiple illumination schemes are provided for either monochrome or color, and in either two-dimensional or time-sequential true stereographic presentation. Light from multicolor sources is superimposed, mixed, and homogenized by mixing light cones with diffractive collectors. Offsetting color overcorrection and undercorrection of individual optical elements achieves overall chromatic correction with minimal optical element complexity; A wireless video signal interface eliminates excess cabling. Additional features include lightweight achromatic eyepiece construction and interchangeable lenslets for peripheral vision correction. Multiple optical elements are injection-molded as a unitary plastic structure, thereby reducing cost and complexity.
