A first fluid is disposed be-tween the cooled surface (30) and the adapter (40) for conducting thermal energy from the cooled surface to the adapter. A second fluid is disposed between the cooling surface (20) and the adapter (40) for conducting ther-mal energy from the adapter to the cooling surface whereby the cooling surface remains free to move axi-ally relative to the adapter (40) at a temperature of the cooling surface at which the first fluid is susceptible to freezing. This allows for movement of the cold finger relative to the dewar and adapter, due to differential thermal coefficients of expansion or support structure motion, without adversely affecting the communication of thermal energy from the load. In the illustrative embodiment, the cooler is a Stirling cycle cooler, the first fluid is thermal grease and the second fluid is nitrogen. The cooling surface (20) is a cylindrical cold finger of the Stirling cycle cooler and the cooled surface (30) is an inner wall of a dewar assembly. The dewar is in thermal contact with a load. The adapter is disposed between the inner wall (29) of the dewar and the cold finger. The adapter (40) has an end cap (42) and a cylindrical housing (44) extending therefrom. The housing (44) extends at least partially along a longitudinal axis of the cold finger (20). An insulator is disposed about the cold finger and the adapter housing. A spring (52) is disposed between a proximal end of the insulator (50) and a base of the cold finger (20) to maintain a distal end of the insulator (50) in contact with the adapter and the adapter (40) in contact with the dewar.

Filed: 1998-11-09
Granted: 2004-08-03
Abstract: An embolic protection device has a collapsible filter element (105) mounted on a carrier such as a guidewire (101). The filter element (105) collapses into the outer end of a catheter (118) for deployment and retrieval through a vascular system of a patient. The filter element (105) has a collapsible filter body with a proximal inlet end and a distal outlet end. The proximal inlet end has inlet openings sized to allow blood and embolic material enter the filter body. The outlet end has outlet openings which allow through passage of blood but retain embolic material within the filter body. After use, the catheter (118) is movable along the guidewire (101) to engage the proximal end of the filter element and close the inlet openings before sliding over the filt er element from the proximal end to the distal end to progressively collapse the filter body on the guidewire (101) for retrieval. The filter element (105) may conveniently be mounted on a tubular sleeve (104) which is slidable and rotatable on the guidewire (101) between spaced- apart stops (106, 120) on the guidewire (101) which allows some manipulation of the guidewire independently of the filter when the filt er is in use.

Title: A support plate having depressions for receiving a hardening compound
Inventor: SCHLUTER WERNER
IPC: E04D11/00
Filed: 1999-04-15
Granted: 2005-07-26
Abstract: The invention relates to a support plate made of a foil-like plastic material, for use with a plate-lined floor structure or a wall so as to create a space between the ground and the surface lining to be applied onto the foil-like plate. The structure of the plate is such that cavities are created by means of, on the one side, projections extending substantially in one direction and, on the other side, raised areas at the same level between which chambers are embodied for receiving a hardening contact medium, such as mortar or adhesive, which forms a contact layer with the surface lining to be applied. According to the invention the structure consists of projections (N1, N2) or (S1, S2) which extend in at least two directions and intersect. The resulting chambers (M1) are delimited in their circumference by the projections (S1, S2), which are open towards the other side of the plate.

Granted: 2010-06-08
Abstract: In a method for determining the flow rate of a fluid flowing in a channel (2), the fluid being constituted by a liquid or a gas, two pulse shaped, oscillating signals are sent through the medium with one signal directed against (14) and the other signal directed with (12) the flow direction (4) of the fluid. The transmitted signals are received and the flow rate is determined by means of the phase shift between the received, pulse shaped signals caused by the flow of the fluid. The phase shift (20) between the signals is determined while compensating for the dwell time of the pulse shaped oscillating signals in the fluid.

Abstract: L'invention concerne un dispositif (10) de détection optique permettant de détecter la présence ou la concentration d'un analyte au moyen de canaux indicateurs et de canaux de référence. Ledit dispositif de détection est constitué d'un corps (12) renfermant une source (18) de rayonnements. Les rayonnements émis par cette source interagissent avec les molécules (16) indicatrices sur membrane (3) indicatrice à proximité de la surface du corps. Une caractéristique optique au moins de ces molécules indicatrices varie en fonction de la concentration de l'analyte. Par exemple, le niveau de fluorescence des molécules indicatrices fluorescentes ou la quantité de lumière absorbée par les molécules indicatrices photo-absorbantes peut varier en fonction de la concentration de l'analyte. En outre, les rayonnements émis par la source interagissent avec les molécules indicatrices situées sur la membrane de référence à proximité de la surface du corps. Les rayonnements (notamment, la lumière) émis ou réfléchis par ces molécules indicatrices pénètrent dans le corps du détecteur, où ils sont réfléchis intérieurement. Des éléments photosensibles situés à l'intérieur du corps du détecteur génèrent des signaux de canal indicateur et des signaux de canal de référence afin de donner une indication précise de la concentration de l'analyte. Selon ses modes de réalisation préférés, le dispositif de détection de l'invention est totalement autonome, et de par sa taille et sa forme, il est destiné à être utilisé in vivo dans le corps d'un être humain. Dans de tels modes de réalisation, il comprend, de préférence, une source d'alimentation, telle qu'un inducteur, qui alimente la source de rayonnements au moyen de dispositifs externes, ainsi qu'un émetteur, notamment un inducteur, servant à transmettre à des capteurs externes le signal représentant la concentration de l'analyte.

Title: Method and device for heating gas from a thin layer of nuclear fuel, and space engine using such method
Inventor: RUBBIA CARLO
IPC: G21D5/02
Filed: 2001-03-15
Granted: 2011-05-17
Abstract: A gas, e.g. hydrogen, at relatively low pressure is directly heated by the fission fragments (FF) emitted by a thin layer of fissile material, e.g. 242mAm, deposited on the inner wall of a chamber which is kept cooled at a typical temperature of about 1,000/1,500 K. The gas is preferably emitted as capillary flow from the walls of cylindrical tubes. Its temperature progressively increases until it reaches an equilibrium value of the order of 9,500 K, at which point FF heating and radiative cooling balance. With a relatively modest surface power density at the foil of 200 W/cm2, the specific, volume-averaged power given to the H gas may be as large as 0.66 MWatt/g. Heating powers up to megawatts for each gram of gas are therefore feasible with acceptable foil surface heating. The gas heating method can be used in rocket engines for deep space propulsion.

IPC: H04M3/00
Filed: 2001-04-11
Granted: 2005-06-07
Abstract: Traffic demands are routed between network elements so as to provide improved protection against network failures. A given tragic demand is routed from a first network element to a second network element, where the second network element is preferably either one of a set of dual-homed elements, or coupled to a dual-homed element, and may also be an element of a ring-type transport or a mesh-type transport. The second network element processes the traffic demand such that a copy of a signal associated with the demand is (i) retained at the second network element, while the signal is routed to at least one additional network element, or (ii) routed to at least one additional network element, while the signal is routed to at least one network element other than the additional network element. For example, in a multidrop connection implemented in accordance with the invention, a copy of the signal is "dropped" at the second network element and one or more additional network elements. In a multicast connection implemented in accordance with the invention, one or more copies of the signal are multicast from the second network element to multiple additional network elements.

Abstract: A dilated N × N optical cross-connect switch suitable for large N  exhibits good efficiency (element count) without a significant increase in and reduced small depth (low loss) and crosstalk. The present arrangement consists of six levels of binary trees of 1 × 2 and 2 × 1 elements. The first two levels form the input stage, the third and fourth levels form the center stage, and the fifth and sixth levels form the output stage. In each of the input, center, and output stages, the odd number level is formed as a binary tree of 1 × 2 elements and the even numbered level is formed as a binary tree of 2 × 1 elements. Each stage is formed by directly joining together the 1 × 2 element binary tree with the 2 × 1 element binary tree. In one embodiment, depth is substantially reduced by using a symmetric arrangement of one or more 2×2 elements located in the vicinity of each junction between adjacent stages. The arrangement also features reduced depth obtained by a Clos type construction.

Abstract: A method is described for temporally aligning a received symbol that is transmitted via orthogonal channels, e.g., OFDM channels, with a reference symbol and/or an earlier received symbol. The method includes computing phases (154) of the first symbol for the orthogonal transmission channels and comparing (157) the computed phases of the first symbol with phases of the reference. The phases of the first symbol are successively displaced by a predetermined phase shift which depends on the channel frequency to obtain a correlation result. The temporal alignment is determined by detecting a correlation maximum based on the correlation result and used to synchronize the first symbol with the reference. The reference can also be an earlier received symbol to provide autocorrelation. The received symbols can be processed by applying a window function, e.g. a Hamming, Hamming or Blackman window.
