Abstract: A method for investigating structural integrity utilizes a carrier member having a flexible surface and a plurality of electromechanical transducer elements attached to the carrier member, the transducer elements being spaced from each other along at least two spatial dimensions. The method includes conforming the flexible surface to a solid structural member, so that a substantial portion of the flexible member is in effective wave-transmitting engagement with the structural member, thereafter transmitting pressure waves from at least one of the transducer elements into the structural member, receiving pressure waves reflected from an internal structural defect in the structural member in response to the pressure waves transmitted from the one of the transducer elements, and analyzing the received pressure waves so as to detect the structural defect.

Abstract: A fingerprint capture or processing apparatus incorporates a casing defining a sealable chamber, a first support in the chamber for holding a source of a chemical fingerprint fixative agent, a second support in the chamber for holding an article to be tested for fingerprints, a filtration system connected to the chamber for removing contaminants from air in the chamber, and an air circulation assembly operatively connected to the casing for circulating air from the chamber and through the filtration system. Preferably, the air circulation assembly is a closed system, ensuring that no contaminants will be spilled to the ambient atmosphere prior to complete cleansing of the air inside the casing. A humidity control device may be connected to the air circulation assembly for modifying a humidity level in the chamber to a predetermined relative humidity, thus optimizing effectiveness of the chemical fingerprint fixation agent.

Abstract: The present invention relates to pyrimidine nucleoside compounds and their use to treat viral infections of Varicella Zoster virus and Epstein Barr Virus, as well as cancers which are complications of Epstein Barr virus.

Abstract: A portable computing device is equipped with multiple display panels. The display panels and hinged, jointed or otherwise disposed to rotate or slide with respect to one another in a transition from a compact configuration to an expanded configuration. In a basic embodiment three output screens take a form of a triptych for which an input panel forms a base. The output panels are deployed with a bend when opened and images angled in towards an observer. The display panels comprise a main panel and two auxiliary panels. In a variation a forth display panel is rotatably or foldably joined to the central display panel so that a total of four display panels may be deployed in a hub and petal configuration. The side panels may be eliminated from the four panel embodiment so that the input panel and two remaining display panels form a vertically orientable triptych with the input panel serving as base.

Abstract: In order to produce pellets or agglomerates in an economically feasible manner from clarified sludge which contains disease-causing bacteria and which is dewatered in a solid mantle worm-gear centrifuge (11) and is subsequently thermally dried in the centrifuge housing (14), and which satisfy the conditions of being hygienically unremarkable and also storage-stable, according to the invention it is proposed that the clarified sludge pellets (25), still hot or warm due to thermal clarified sludge drying, are held at their temperature in a sanitizing apparatus (26) for a dwell time of at least 10 min and thus sanitized and additionally dried.

Abstract: An apparatus for interfacing between a mobile switching center (MSC) and an inter working function unit (IWF), comprising an inter-system link protocol (ISLP) processing part for processing a plurality of subhighway (SHW) data inputted respectively through SHWs in the unit of subscribers according to an ISLP. The ISLP processing part further separates data transferred over a given channel of an E1 trunk from the IWF according to the SHWs and their time slots and transfers the separated data respectively to the subscribers. A dual port random access memory (RAM) stores the subscriber-unit data processed by the ISLP processing part in the unit of channels or the data transferred over the given E1 trunk channel from the IWF in the unit of the subscribers.

Abstract: The present invention relates to a universal joint shaft which includes a driving shaft and driven shaft engaged to a driving yoke and driven yoke which are arranged in an installation position and have opposite both front ends which are distanced and a rectangular cross section in a radius direction, and a three-divided joint formed of connection shafts and having a cross section in a radius direction to correspond to the driving shaft and driven shaft for implementing a radius direction slip and rotational force transfer between the driving shaft and the driven shaft, wherein the universal joint shaft includes a driving yoke and a driven yoke for transferring a rotational force in an inclined state at a certain angle.

Abstract: A rotatable coupling structure for a shield and visor of a helmet includes a rotation shaft unit installed at both sides of the helmet body. The shield includes a rotary shaft inserted into a shaft hole in a circular rotation plate member through insertion guide portions at both ends. The visor includes a respective rotary shaft inserted into a shaft hole in the circular rotation plate member. The shield is coupled to the shaft hole of the respective rotary shaft and is rotatable upward and downward at multiple stage stop points, and the visor is assembled to the shaft of the rotary shaft and is fixed at a fixed position without an upward and downward rotation.

Abstract: A self-actuating firearm comprising a frame, a breechblock, a barrel provided with a bore, a cylinder which is associated with the barrel and forms an internal chamber which is connected to the bore of the barrel, by means of a gas tap, and a piston which is at least partially accommodated in the chamber and can be actuated by the gases that arrive from the bore upon firing. The piston floats with respect to the cylinder and the frame and comprises a portion which is external to the cylinder and is adapted to act with an impulsive action on the breechblock in order to recock the firearm upon firing.

Abstract: The present invention relates to a repelling force apparatus of a power steering system for a vehicle which is capable of obtaining various type linear and/or non-linear characteristics in a state that the characteristic of a valve is varied based on a running speed of a vehicle. There is provided a repelling force apparatus of a power steering system for a vehicle in which the teeth formed in a pair of the rotational ferromagnetic members are formed in a trapezoid shape, and the sizes of the opposite surfaces of the same are different in the repelling force apparatus of a power steering system for a vehicle having a plurality of teeth which are opposite each other based on 1:1 in a pair of rotational ferromagnetic members wherein there are provided an exciting coil, a permanent magnet and a pair of rotational ferromagnetic members.

Abstract: The present invention is directed to monomeric and polymeric compositions based upon polymeric urethane surfactants which are derived from linear, branched, or aromatic compounds of synthetic or natural origin, preferably from tertiary amines and diisocyanate compounds. The urethane polymers of the present invention may be in the form of betaines, quaternium salts, tertiary amine salts or N-oxides. The compounds of the present invention may be incorporated into personal care formulations such as cosmetics, dental care products and toiletries to improve at least one and preferably two or more characteristics of such formulations.

Abstract: An antenna for a mobile communication terminal in which part of an antenna rod is slidably mounted into an assist antenna rod such that the antenna may be selectively extended in one or two stages. A connecting portion between the antenna rod and the assist antenna rod is rolled so that the antenna rod is prevented from being easily escaped from the assist antenna rod when the antenna is extended in two-stage. Thus, an enhanced communication quality may be obtained by extending the antenna length even when the mobile communication device is slimmed and an optimized length of the antenna is not secured.
