Abstract: An in vivo drug concentration distribution measuring device for measuring, when a drug having an imaging function is administered, in vivo concentration distribution of the drug is disclosed.

Abstract: An avian eggshell egg-check/crack detection system was developed to aide official egg graders. It includes an imaging system and a device to produce negative pressure in an egg chamber.

Abstract: A device (1) for inspecting objects with a substantially spherical surface, such as for example eggs or fruit, comprises optical observation means (8) for observing the objects. The device has a supporting surface (10) for supporting the objects. There is a light source for illuminating the objects. The device also comprises a box (2) with reflective walls (3a, 4b and 4a shown) which is positioned above the supporting surface (11). The light source and the observation means (8) are accommodated in the box (2). A plurality of objects can be placed next to one another on the supporting surface (10) and can be illuminated equally well.

Abstract: Shotgun shell testing apparatus positions a loaded shotgun shell in the path of a light source. An observer, generally a shooter, places his or her supposedly properly loaded shotgun shell in a receiving space of this apparatus and turns on the lighting energy source. By observing the resulting internal derived image of the fiber derivative portions of the shell casing, often observable at the exterior of the apparatus, and comparing this image observed with the likeness of an earlier image reflecting a properly loaded shotgun shell of the specified power charge, a shooter is able to determine if the shotgun shell being tested, via this observation, has been correctly loaded in respect to the positioning of the powder, wad, and shot.

Abstract: An improved barricade is composed of two identical, hollow, molded plastic panel units which are bolted together at top hinges. Novel detents lock the barricade in an open position for use. This mechanism allows for folding and storage by pushing the legs together with a substantial force. The panel units incorporate reinforcing ribs on the legs that taper off at their top and cooperate with opposing leg members and a specially shaped hinge section to allow for flat, compact storage. Horizontal panels are flush to the surface of the panel unit for optimum strength and space utilization. Bottom portions of the hollow panel units are filled with sand as a ballast to increase stability. A special mounting bracket is attached next to one of the hinges to support attachments such as flashers.
