Abstract: A threaded, dual needle system is securely attached to a modified subcutaneous venous access port having an internal reservoir, used for intravenous drug therapy particularly in human cancer treatment. A hollow outer needle is paired with a removable, male-threaded solid inner point and inserted through the patient's tissue and through the port's protective, self-sealing silicon septum, and the solid inner needle is then removed, while the outer needle is left in place. Next, a hollow inner needle is threaded through the outer needle to a depth sufficient to interlock with a female-threaded port receptacle at the base of the port's fluid reservoir and rotated to install. Optional additional threading can permit securing the outer needle to the two inner needles. A breakaway system prevents displacement from unintended pulling of the flow-line. The system thus provides additional protection against needle displacement from venous access ports, the resulting leakage, and the problems caused thereby.

Abstract: Assemblies and methods for interconnecting integrated circuits, particularly prepackaged ones, are disclosed. A multi-level electrical assembly--composed of a pin carrier, a set of pads, such as for receiving a surface-mounted integrated circuit, and a set of conductive pathways coupling the pads and the pins--can connect one or more integrated circuits to the socket or other attachment area of a circuit board. The pathways pass through a multi-layered interconnect board, which can be configured to permit any translation of pads to pins for different purposes, or to permit the coupling of additional circuit elements, such as a coprocessor or passive circuits, to the pathways. Inventive methods for forming the assemblies, and inventive systems in which the embodiment of the assembly can be used to increase circuit board density, are also disclosed.

Abstract: The invention is in the field of three-dimensional hollow novelty items and their manufacture, particularly items such as artificial pumpkins that the consumer desires to carve or alter after purchase. Disclosed is a carvable novelty article, such as an artificial Halloween pumpkin, comprising a polyurethane shell substantially surrounding an interior volume and having a thin, elastomeric coating, such as an acrylic, on the exterior surface of the shell. The carvable article can be formed by an inventive process in which polyurethane foam material, such as material having a nominal density of about 2.5-3.0 pounds per cubic foot, is sprayed from a nozzle rotating with respect to the inside of a mold. After the polyurethane foam article and the mold are separated, the article is coated with an elastomeric coating, such as an acrylic material that is applied as a liquid.

Abstract: An MPEG-2 decoder circuit achieves smaller circuit area, and hence lower cost, by using circuitry, including ROMs, designed to implement residue arithmetic to calculate discrete cosine transforms in a pipelined or iterative fashion. A variable-length decoder based on ROM-like PLAs parses the stream of data to separate audio from video data and to direct the necessary operations on the data elements. The decoder and data flow through the system are controlled by a conditional MOVE processor, which is implemented as a data memory.

Abstract: In connection with downhole placement of proppant materials for the purpose of enhancing oil recovery through a subsurface fracture-stimulation treatment, phenolic resin activator is injected after resin-coated proppant is pumped. The results are a reduced probability of problems attendant to premature screenout, savings in the quantity of activator needed, more concentrated placement of the activator close to the wellbore, and the ability to continue the fracturing treatment longer. Injection of activator is accomplished through tubing extending at least as deep as the perforations, while injection of proppant is done through the tubing-casing annulus.

Abstract: An automatic, controlled manipulator includes a moveable tool head on an arm and a tool supported at the end of the arm. The manipulator may be moveable in multiple or all directions. A storage for remotely generated control signals can be accessed to control motors causing 3D motion of the tool head, attachment of the tool, and (if applicable) motion of the manipulator, and also to control power to operate the tool. Video signals generated at the manipulator are used to identify the workpiece, to select one of a plurality of stored control programs, and to select the tool operations applied.

Abstract: An omni-directional taxiway light uses an axially symmetric conjugate lens pair to distribute lamp light, particularly substantially parallel to the taxiway surface, while protruding minimally above the surface. An associated fixture contains a housing holding the optical elements in fixed relative positions and a weather-proof seal arrangement.

Abstract: A system and method are provided for enabling machine operations. In particular, the invention includes an electronic device that senses or scans one or more physical characteristic of a person about to operate a machine and generates signals indicative of such physical characteristic(s), which signals are automatically analyzed and compared with signals stored in a memory to generate control signals for enabling the operation of the machine. In a particular form of the invention, both the presence of a person at a machine and an identifying characteristic of such person are sensed and used to enable the operation of the machine.

Abstract: A carrier delivered dressing is disclosed which has a conformable backing with a pressure sensitive adhesive coated on a bottom face and a low adhesion coating on a top face. The backing is supported during shipping and handling by a liner attached to the adhesive and a removable heat sealed carrier attached to the top face of the backing. The method according to the present invention discloses the steps of forming and optionally removing windows in a carrier material and nonpermanently heat sealing the carrier to the backing to form the dressings of the present invention.

Abstract: To suppress electromagnetic interference across a wide range of frequencies, in both magnetic and electrical fields, an emissive wire is surrounded by a ferrite core having an outer surface covered with a metal foil. The metal foil on the core or cores is grounded. If multiple cores are used in proximity, the foils of the several cores are electrically coupled together. In one embodiment, an omni-directional strobe light like the one shown in U.S. Pat. No. 5,155,666 is shielded by placing pairs of foil-covered ferrite cores around the wires at each apex of the polygon formed by the interconnected flash tubes, grounding the cores to the nearest lamp reflector, and grounding the reflectors together.

Abstract: Assemblies and methods for interconnecting integrated circuits, particularly prepackaged ones, are disclosed. A multi-level electrical assembly--composed of a pin carrier, a set of pads, such as for receiving a surface-mounted integrated circuit, and a set of conductive pathways coupling the pads and the pins--can connect one or more integrated circuits to the socket or other attachment area of a circuit board.

Abstract: Video apparatus and methods include systems used for generating animated pictures and displaying them on an electronic display screen. Sets of discrete image signals corresponding to still images, such as parts of a specific animated display, are received and stored at a selected location in a storage member, which location is identified by corresponding location codes assigned to the image signals. The assigned location codes may also be used to reproduce from storage those image signals corresponding to a selected animation phenomenon. Discrete video display signals corresponding to the selectively reproduced discrete image signals are generated, and the display signals are transferred to a video storage device, from which the signals can be reproduced. When it is desired to display a specific animated sequence, a series of still images is reproduced and displayed on a video display screen.
