Abstract: An electrode catheter for cardiac electrophysiology. An elongated body suitable for intravascular insertion surrounds a plurality of electrode lead wires. A composite electrode comprises a plurality of tip electrodes and defines a margin along a proximal edge. Each tip electrode is electrically connected to an associated electrode lead wire and is adjacent to another tip electrode on at least one side along an axis of the elongated body. Each tip electrode is separated from the another tip electrode by insulation. A cup electrode is electrically connected to an associated electrode lead wire and defines a cavity shaped to overlap the margin of the composite electrode. The cup electrode is fixedly secured to the composite electrode and to a distal end of the elongated body and is separated from the composite electrode by insulation.

Abstract: According to the present invention a method and a receiver for high-frequency signals is
provided. The receiver comprises a power divider (4) to divide a modulated RF input
signal in at least two branches. At least one delay line (5, 6) provides for a delay of the
branches relatively to each other by a predetermined delay constant. A calculation circuit
(7, 8) calculates at least three power levels based on combinations (12, 13, 14) of the two
branches of the input signal relatively delayed (5, 6) to each other. A processing means
(10) calculates the phase and the amplitude of a complex signal representing the relation
between the two branches of the input signal relatively delayed to each other, on the basis
of the said at least three power levels (8). 
     The invention therefore provides for a direct 6-port receiver based on non-coherent
detection. The concept of the invention is inherently cheap and features high integration
ability and low-cost processes. Ideally the whole RF front end can be placed on one chip.

Abstract: The method involves first positioning the parts and fixing them together, at least in some regions, using a copper alloy or pure copper weld material. After this, the parts are heated in a protective gas atmosphere until the applied weld material melts. The weld material diffuses partially into the components in the region of the joint. The material then finally hardens.

Abstract: Standard, unfixed electrophotographic images are transferred from a photoconductor drum (5) to paper (7) at a nip location with a transfer roller (3). The paper remains in contact with the transfer roller until it is positioned under a ink jet printhead (9), where a second image, typically color highlights, is printed. This configuration requires no additional registration of the two images. The ink jet printhead may be charged to repel stray toner which might clog its nozzles. The transfer member may be a belt or may be large enough to permit movement of the paper at the higher speeds of electrophotographic at the transfer station and at the lower speeds of ink jet printing when the paper is at the ink jet printing station.

Abstract: An improved titanium nitride barrier layer that prevents spiking between an overlying aluminum layer and a silicon substrate is formed by first sputter depositing a titanium layer onto the substrate, forming an oxygen-containing titanium layer thereover, and sputter depositing a titanium nitride layer over the oxygen-containing layer. The oxygen-containing layer can be formed in an oxygen-containing plasma, or titanium can be sputtered in the presence of oxygen. The titanium nitride layer can also be treated with an oxygen-containing plasma. Robust titanium nitride barrier layers are formed that can prevent spiking by an overlying aluminum contact layer, even after heat treatment up to 550°C.

Abstract: The present invention relates notably to a method for sharing a transmission medium between communication apparatuses having an identifier, each adapted on the one hand to transmit messages by means of the said transmission medium, during so-called "transmission" phases, and/or on the other hand to receive messages by means of the said transmission medium, during so-called "reception" phases. 
     Each communication apparatus stores, in each reception phase, and associated with identifiers, activity states representing the last messages transmitted by the communication apparatuses having these identifiers, in their own transmission phases. 
     In a so-called "transmission preparation" phase preceding each transmission phase, each communication apparatus determines, according to first predetermined rules taking into account at least certain of the said activity states, at what moment it can transmit a message on the transmission medium.

Abstract: A system is provided for providing syringes filled with pharmaceuticals whose components must be stored separately, using an active ingredient in a pharmaceutical vial (2), a diluent in a protosyringe such as a bottomless vial (4) or a cartridge, and a combiner assembly which enables the content of the pharmaceutical vial to be transferred into the protosyringe and converts it into a ready-to-use syringe on activation. The combined assembly included a tubular body (22, 24) having recesses (30, 31) at opposite ends for receiving capped ends of the vial (2) and the protosyringe (4), and a hub (34) and needle (40, 44) assembly between penetrable sheaths or shields (46, 64) which acts on activation of the assembly to enable the transfer and conversion referred to above. Components of the system may also be used to convert protosyringes and pharmaceutical vials containing pharmaceuticals into delivery systems.

The drum has an internally threaded hub at one end that is engagable with a threaded stub shaft of the crank. The hopper has an improved integral support handle and also is associated with an improved press plate with an integral support arm. The arm pivotably extends adjacently to the handle, both the handle and the arm are graspable by one hand. The grater has few components, and the food contacting components thereof can be readily dissembled so that the entire grater is easily cleaned after use.
