  • ILLUMINATION DEVICES INCLUDING MULTIPLE LIGHT EMITTING ELEMENTS
    Publication number: 20240151895
    Abstract: A variety of illumination devices are disclosed that are configured to manipulate light provided by one or more light-emitting elements (LEEs). In general, embodiments of the illumination devices feature one or more optical couplers that redirect illumination from the LEEs to a reflector which then directs the light into a range of angles. In some embodiments, the illumination device includes a second reflector that reflects at least some of the light from the first reflector. In certain embodiments, the illumination device includes a light guide that guides light from the collector to the first reflector. The components of the illumination device can be configured to provide illumination devices that can provide a variety of intensity distributions. Such illumination devices can be configured to provide light for particular lighting applications, including office lighting, task lighting, cabinet lighting, garage lighting, wall wash, stack lighting, and downlighting.

  • Immunoassays for prostate specific antigen
    Patent number: 5672480
    Abstract: The present invention relates to the field of cancer immunoassay. Specifically, a new immunoassay method for prostate specific antigen (PSA) is presented. Also presented is a complex which resembles a complex of PSA and .alpha.-antichymotrypsin (ACT) that can be used as a calibrator or control in an immunoassay for PSA. Further presented is a method for fractionating polyclonal antibodies, to PSA, into those which bind epitopes that are masked by the binding of PSA to ACT and those which do not bind such epitopes.
