Abstract: A system and method for surfacing content relevant is described. The system computes a rank score for each item of a plurality of items that are accessible from a user of an enterprise application. The system identifies a set of relevant items from the plurality of items based on the rank score for each item of the plurality of items. The system surfaces the set of relevant items within a context of a communication application of the user without receiving, from the user, a query for any of the items in the set of relevant items.

Abstract: An optical system for a night vision video camera having a pair of mirrors with an optical prescription providing f/2.8 speed and 50 line pairs per line millimeter resolution to an image intensifier located between the two mirrors on the common optic axis of the mirrors. The mirror first receiving the image to be viewed is an f/4 parabolic mirror and the second mirror is an f/10 spherical mirror with an external diameter of about forty percent of the diameter of the parabolic mirror (i.e., the obsuration ratio is about 0.40). The second mirror receives the reflected image of the object viewed by the night vision video camera from the first mirror and reflects the image to the image intensifier. The image may be viewed at a external view finder and can also be recorded.

Abstract: A device and method for detecting fluorescent evidence, including fingerprints. The device and method use a pair of matched filters, a source of noncoherent light, and a light intensifier to detect the wavelength-shifted luminescence from fluorescent substances. The light source and a first filter illuminate the substances with a light of predetermined band width. The second filter and the light intensifier detect and increase the luminance of the reflected light, shifted to a longer wavelength by luminescence from the florescent substances. The device may be hand-held and portable. The intensified light image may be displayed locally and/or may be transmitted to a remote receiver and displayed so that evidence may be detected remotely.
