Granted: 2008-02-12
Abstract: A fault interrupter is provided that includes a high-speed disconnect in series with an interrupter wherein the circuit opening is via the interrupter and the circuit making is via the disconnect. A stored energy disconnect operating mechanism operates the disconnect between ground, open and closed positions and also charges the interrupter mechanism during a slow opening of the disconnect without fully charging the disconnect operating mechanism. Thus, the required operating forces to open the disconnect and charge the interrupter mechanism are reduced. During a manual opening, the disconnect operating mechanism trips open the interrupter, then only partially charges to begin opening the disconnect before releasing the stored energy. Continued operation of the disconnect operating mechanism slowly drives the disconnect open while charging the interrupter mechanism and closing the interrupter. The interrupter mechanism remains charged during operation of the disconnect between the open and ground positions by the disconnect operating mechanism.

Abstract: A system and method provide sophisticated analysis of program viewership by executing interactive applications that generate responses describing the viewers' behavior. A broadcast server maintains a database of interactive applications each preferably associated with a program that will be broadcast. The interactive applications preferably include monitoring interactive applications that are configured to selectively monitor viewership, interactive application usage, and reception terminal usage. When the program is broadcast, the monitoring interactive application is inserted into the broadcast feed and delivered to a broadcast receiver such as a television set-top box. The broadcast receiver includes a processor, memory, and other hardware necessary to execute the interactive application. When executed, the interactive application monitors usage of the broadcast receiver, including, for example, the program watched by the subscriber, the entry and exit paths to the program, whether the volume was changed during the program, and the usage of interactive applications. The monitored data is sent in a response packet to a local data center at, for example, the cable headend. The local data center supplements the response with subscriber information from one or more subscriber databases, including marketing information such as the subscriber's age, race, and income. Information about all of the subscribers is aggregated by the local data center and transmitted to a master data center. The master data center aggregates all of the received information, supplements it if possible with additional subscriber information, and provides reports to the broadcaster indicating the geographic, demographic, and psychographic profiles of the program viewers.

Abstract: A multilayer composite tubular structure (10) for use as a scent in surgical procedures has an outer layer of biocompatible material (12), a middle layer of radiopaque material (14), and an inner layer of biocompatible material (16).      The layers are metallurgically bonded, to form a composite stent (10) which is ductile and permits large deformation without delamination between the biocompatible (12, 16) and radiopaque layers (14). The composite structure (10) formed is visible on a fluoroscope, yet does not obstruct the details of the stent (10) itself, or of the anatomical features surrounding the stent (10). A process of forming a multilayer composite tubular structure (10) is also disclosed. A tube formed from radiopaque material (14) is coaxially surrounded by a tube of biocompatible material (12, 16).      The tubes are simultaneously reduced, such as by tube drawing, swaging, or deep drawing, until a composite structure (10) of a desirable diameter and wall thickness is formed. The tubes are then heat treated to cause diffusion bonding of the biocompatible (12, 16) and radiopaque layers (14).

Abstract: The Invention relates to Agriculture in general, and, to the means and devices for pre-sowing seed treatment.      In the mentioned above Invention, not less than 5 % of seed is exposed to rotating polarized incoherent light in the bandwidth of 630.0 to 680.0 nm, and monochromatic polarized coherent light in the wavelength range from 630.0 to 640.0 with an electric vector variability and phase change of 0 to 180 °. The treated seed is then mixed with the non-treated seed.      The treated seed actively absorbs light quanta and becomes highly exited, starting to radiate light quanta in the bandwidth of 210 to 660 nm, with the energy 2 to 4 times exceeding the energy of absorbed quanta. After the mixing of the treated and non-treated seed, the biological luminescence of the treated seed creates a phenomenon of bioenergetic seed interaction, thus forming stable bioenergetic structures, bearing higher volumes of free energy.      Such treatment is characterized by high quality treatment results and lowered costs of the treatment itself.      The treatment device consists of sources of incoherent polarized light, positioned spiral-like as to the seed flow, and a unit combining a source of monochromatic polarized coherent light with a scanning mechanism with mirrors equipped with at least two semilucent reflecting layers, positioned one behind the other.

Title: Semi-interpenetrating or interpenetrating polymer networks for drug delivery and tissue engineering
Inventor: LANGER ROBERT S
IPC: A61L27/50
Filed: 1998-05-22
Granted: 2009-10-20
Abstract: Compositions for tissue engineering and drug delivery have been developed based on solutions of two or more polymers which form semi-interpenetrating or interpenetrating polymer networks upon exposure to active species following injection at a site in a patient in need thereof.  The polymers crosslink to themselves but not to each other; semi-interpenetrating networks are formed when only one of the polymers crosslink. The resulting viscous solutions retain the biologically active molecules or cells at the site of injection until release or tissue formation, respectfully, occurs. As a result of studies conducted with polymer-cell suspensions forming interpenetrating polymer networks, it has been determined that polymer solutions can be formulated wherein the active species is provided by exposure of the polymer solution to an exogenous source of active species, typically electromagnetic radiation, preferably light. Studies demonstrate that light will penetrate through skin, body fluids (such as synovial fluid) and membranes and polymerize the polymer solutions. The polymer solutions can be crosslinked ionically or covalently, to form a hydrogel, semi-interpenetrating polymer network or an interpenetrating polymer network.

Abstract: A drogue assembly (10) for in-flight refuelling includes a circumferential array of triangular support arms which carry a drogue parachute (29) which extends circumferentially around their shorter sides.  Each support arm is pivoted and mounted on a pivot pin (19) at its apex for pivotal movement in a radial direction. At least alternate ones of the support arms carry leaf springs which extend into pockets (51) formed in the drogue parachute (29). The leaf springs act on the drogue parachute (29) in opposition to air pressure loading on it in flight so that it tends to increase the chord angle of the drogue parachute (29) from the leading edge. Hence the effective area of the drogue parachute in flight is varied automatically above a certain predetermined minimum which depends on the dimensions of the trailing edge so it is reduced as air speed is increased and vice versa.
