Abstract: An implant may be used for implantation into tissue of a body. The implant includes an elongated conduit and a loop. The elongated conduit has an interior passageway for conducting fluid. The loop has an interior circumference with a fluid conducting channel formed therein. The channel is interconnected with the interior passageway for delivery of fluid between the channel and the interior passageway.

Abstract: An apparatus and method for providing image primitives, such as edge polarity, edge magnitude, edge orientation, and edge displacement, and derivatives thereof, for an object are described. The data are obtained substantially simultaneously and processed in parallel such that multiple objects can be distinguished from one another in real time.

Abstract: A tube for implantation into the eye for replacement conduction of aqueous humor from the chambers of the eyeball to the subconjunctival tissue and ultimately to the venous system is comprised of an elongated fluid conducting conduit having distal and proximate ends, a sidewall and an interior passageway and at least one longitudinally extending opening in the sidewall that exposes the interior passageway and at least one nidi-forming structure carried by the conduit and extending laterally therefrom to implement the formation of at least one aqueous filtration bleb in the tissue of the eyeball. In one embodiment, the tube also contains at least one releasable ligature circumscribing the conduit. In another embodiment, the tube also contains an anchor appended to the conduit to prevent it from migrating from its placement site.

Abstract: The present invention provides a device and a process for detecting an analyte in a biological fluid. The device comprises a separating matrix for separating analyte from the fluid and means for detecting the analyte, where the separating matrix contains HEPES buffer, preferably in an amount between 70 and 150 millimolar. The process comprises applying the sample to the device having a separating matrix and then detecting analyte in the sample using the detection means. The presence of HEPES in the separation layer shortened the detection time.

Abstract: The present invention provides a device and a process for detecting an analyte in a biological fluid. That device comprises a cover portion with a restricted area for sample application, a separation matrix for separation of the analyte from substances in the sample that can interfere with detection of the analyte and means for detecting the analyte. The restricted area of sample application is less than 90 percent of the cross-sectional area of the separation matrix and the separation matrix and the means for detecting analyte are under compression of between 14 to 43 percent. A process comprises applying a sample of fluid to such a device and detecting a signal generated from an interaction between the analyte and the detection means in the device.

Abstract: An artist's palette of any suitable configuration having at least three pairs of designated areas (A,B,C) in an adjacent relationship. Each pair of areas provided to receive a first color. Each designated area (11, 12, 13, 14, 15, 16) of each pair having a directional indica towards the adjacent pair of designated areas. Each designated area of each pair being provided to receive a first color with a second color bias wherein adjacent designated areas of adjacent pairs having directional indica towards each other and receive a first color having a common second color bias. The palette having at least three areas (17, 18, 19) positioned between adjacent pairs of designated areas to receive a second color. The second color created by combining the first colors having a common second color bias in adjacent designated areas.
