A single element infrared detector consisting of multiple layers of succeve epilayers of lead chalcogenides or their alloys with tin or cadmium to form two or more adjacent contiguous surfaces whereupon each surface is deposited with an ohmic contact. The multiple adjacent semiconductor surfaces are also each fitted or equipped with an non-ohmic contact that yields novel applications in terms of broad band and narrow scanning, particular when the epilayers are geometrically arranged to selectively allow the transmission of radiation to yield both broad band and narrow band responses concurrently so as to obtain a separate electrical signal from each adjacent contiguous semiconducting epilayer surface.
An infrared detector device for at least two wavelengths, i.e. 3 to 5 microns and 8 to 14 microns, comprises detector elements (10 and 20) formed in two or more infrared-sensitive materials with different badgaps, e.g. in cadmium mercury telluride. These materials may be provided side-by-side in a single level on a substrate (3) or preferably as different levels (1 and 2) on the substrate (3). Each detector element (10 and 20) comprises a p-n junction (11 and 21) between opposite conductivity type regions (12,13 and 22,23). Electrical connections (15,25,24) extend from these regions to the substrate (3). Freedom in design and fabrication is obtained by a connection structure in which one connection (25) of the longer-wavelength response element (20) contacts both the semiconductor material (2) of that element (20) and the larger-bandgap material (1) of the shorter-wavelength response element (10), at a side-wall (42) of both materials. The larger-bandgap material (1) comprises a further region (18) which adjoins the side-wall (42) and which forms a further p-n junction (19) electrically in parallel with the p-n junction (21) of the longer-wavelength detector element (20).
An image pickup apparatus comprises color separation means for separating light from a subject into a plurality of colors, and a plurality of image pickup means provided for each of the plurality of colors, each image pickup means having a plurality of pixels, and each pixel having a gate conductor at a light receiving surface. The thickness of the gate conductor of each image pickup means is different for each image pickup means.
The present invention provides a method of connecting a reconstitution device to a drug container having a top and a closure. The method includes the steps of: providing a reconstitution device having first and second ends, the second end having a receiving chamber dimensioned to receive the top of the container for fixedly attaching the device to the container, the device having a central channel housing a piercing member, the device further having first and second sleeve members capable of sliding axially with respect to one another from an inactivated position where the piercing member is outside the receiving chamber to an activated position where a portion of the piercing member is positioned inside the receiving chamber; and inserting the top of the container into the receiving chamber of the device and fixedly attaching the container therein when the device is in the inactivated position.
The present invention provides a connector device for establishing fluid communication between a first container and a second container. The device has a first sleeve member having a first end and a second end and a sidewall defining a chamber, the first sleeve member having at the first end a first attaching member adapted to attach to the first container. The device further has a second sleeve member having a first end and a second end, the second sleeve member being associated with the first sleeve member and is movable axially with respect thereto from an inactivated position to an activated position. A second attaching member is positioned on the second end of the second sleeve and adapted to attach the second sleeve member to the second container. A piercing member positioned in the chamber and projecting from one of the first and second sleeve members is provided for establishing a fluid flow path from the first container to the second container. The piercing member is hermetically sealed.
The present invention provides a reconstitution device (10) for placing a first container (12), such as a liquid container (e.g. flexible container or syringe), in fluid communication with a second container (14), such as a drug vial. To this end, there is provided a connector device (10) for establishing fluid communication between the diluent container (12) and the drug vial (14). The connector device (10) has a first sleeve member (32) having a first end (36) and a second end (38). The first sleeve member (32) has at the first end (36), a first attaching member (30) adapted to attach to the liquid container (12). The connector device (10) also has a second sleeve member (34) having a first end (48) and a second end (50). The second sleeve member (34) is movable axially with respect to the first sleeve member (32) from an inactivated position to an activated position. The second sleeve member (34) has a protuberance (66) on an inner surface of the second sleeve member (34). A second attaching member (28) is attached on the second end (50) of the second sleeve member (34) and is adapted to attach to the second container (14). The second attaching member (28) has a sealing member (84). A piercing member (76) is positioned in the chamber and projects within the sleeve members (32,34) for providing a fluid flow path from the first container (12) to the second container (14). The piercing member (76) is moveable from a first position in the inactivated position to a second position in the activated position wherein the piercing member (76) moves past the protuberance (66), the protuberance (66) preventing movement of the piercing member (76) back to the first position. The device (10) is movable from the inactivated position to the activated position by a force generally applied to the device outside the liquid container (12).
