Title: Aiguille pour administration intradermique de substances a moyens limitant la penetration
Inventor: HARVEY NOEL G
IPC: A61M37/00
Filed: 2001-06-29
Granted: 2009-10-27
Abstract: L'invention concerne des procédés perfectionnés pour l'administration intradermique de médicaments et d'autres substances à des humains et à des animaux. Ces procédés font appel à des aiguilles indicatrices, notamment des microaiguilles, placées dans la zone intradermique pour y administrer une substance sous forme de bolus ou de perfusion. On a découvert que le positionnement de l'orifice de sortie de l'aiguille à l'intérieur de la peau et la hauteur à découvert de cet orifice sont critiques pour une administration efficace de substances actives avec de petites aiguilles indicatrices, si l'on veut éviter les fuites de substances hors de la peau et améliorer l'absorption dans la zone intradermique. La pharmacocinétique de médicaments hormonaux administrés conformément aux procédés de la présente invention s'est avérée très similaire à la pharmacocinétique de l'administration sous-cutanée classique, montrant que l'administration intradermique conformément aux procédés de la présente invention produit vraisemblablement un résultat clinique similaire (donc une efficacité similaire), avec l'avantage de réduire ou d'éliminer la douleur pour le patient. Des dispositifs d'administration qui placent l'orifice de sortie de l'aiguille à une profondeur adéquate dans la zone intradermique et qui régulent le volume et le débit du fluide administré assurent l'administration correcte d'une substance dans la zone souhaitée et sans fuite.

Title: Infrared thermographic screening technique for semiconductor-based chemical sensors
Inventor: MCCARRON EUGENE MICHAEL
IPC: G01N27/00
Filed: 2001-10-15
Granted: 2010-07-20
Abstract: An infrared thermographic technique for rapid parallel screening of compositional arrays of potential chemical sensor materials has been developed. The technique involves applying a voltage bias and the associated current to the sample array during screening. The thermographic response is amplified by the resistance change that occurs with gas adsorption, and is directly monitored as the temperature change associated with I2R heating. This technique can also be used to determine n- or p-type character for the semiconductor in question.

Title: Shutter drive mechanism for outdoor floodlight
Inventor: BAROZZINI CLAUDE
IPC: F21S8/00
Filed: 2003-09-03
Granted: 2009-11-24
Abstract: A shutter drive mechanism for an outdoor floodlight is described herein. The shutter drive mechanism and outdoor floodlight has an outer housing which surrounds the light fixture and also which protects the light fixture and a drive mechanism from the elements. Extending outward from the housing is a drive vale which supports the drive mechanism for raising and lowering a rigid shutter which covers the lens of the light fixture so that the light may be doused readily without turning off the lamp. The planar shutter moves horizontally or vertically within rails through a first and second slide, the shutter moveable by a drive arm which is affixed to a runner retained within a runner guide and driven by a screw drive. The shutter is actuatable between an opened and closed position such that the light fixture is adequately doused while the lamp remains on.

Title: Method and apparatus for the detection and ligation of uterine arteries
Inventor: BURBANK FRED H
IPC: A61B17/128
Filed: 2002-03-27
Granted: 2009-08-11
Abstract: The invention provides devices, systems and methods for occluding arteries without puncturing skin or vessel walls. The devices, systems and methods for occluding arteries are configured to be applied to arteries externally of the arteries. Occlusion may be temporary or permanent, and may be partial or complete. Clamping a device to tissue near to an artery is effective to compress tissue around the artery and to indirectly compress the artery. The methods, devices and systems of the invention find use in, for example, treatment of uterine disorders and conditions which may be treated by occlusion of the uterine arteries. A uterine artery may be access via a patient's vagina by compressing a portion of the vaginal wall around a portion of a uterine artery to occlude a uterine artery. Clamping of an artery may also be performed by clamping a device directly onto an artery.

Title: Orbital pallet wrapping machine and method
Inventor: WILEY ROBERT B
IPC: B65B11/02
Filed: 2002-06-13
Granted: 2008-11-18
Abstract: A stretch-wrapping machine (20) consists of a revolving ring (140) with a packaging material dispenser (120) mounted to it. The ring (140) revolves about a horizontal axis to dispense the stretch wrap material around a load (40) that is supported by a forklift (30). The revolving ring (140) is mounted on a track (70) to allow the ring to travel back and forth in a direction perpendicular to the ring. This allows the machine to wrap any load (40) that fits within the ring. Thus the length and the weight of the load do not limit the wrapping capability of the machine.

Granted: 2017-02-14
Abstract: A method of producing a mainly carbonate bonded article comprises a step of providing an alkaline granular material comprising one or more alkaline earth metal silicate phases. The method comprises a step of compacting the granular material to obtain a compact of the granular material. The porosity of the compact is smaller than or equal to 37% by volume. The intrinsic permeability of the compact is at least 1.10-12cm2.  The method also comprises a reacting step arranged to form at least 5% by weight of carbonates (CO-23), by reacting the granular material with carbon dioxide in the presence of water, thus transforming the compact into the article. In the reacting step, the compact, being unsaturated with moisture at the beginning of the reacting step, is brought in an atmosphere comprising said carbon dioxide.  The atmosphere is at a temperature of at least 70°C and at a pressure of at least 0.5 MPa.  The pressure is also higher than the saturated vapour pressure of water at said temperature.  As a result, at least a portion of said carbonates are formed by reaction of the one or more alkaline earth metal silicate phases. The invention is also related to an article obtained by the method.

Title: Suture anchor and approximating device
Inventor: YEUNG JEFFREY E
IPC: A61B17/00
Filed: 2002-12-24
Granted: 2007-11-06
Abstract: An elastically curved suture anchor is resiliently straightened and delivered into tissue by a needle. When the needle is withdrawn, resumption of the curvature provides leverage for anchor rotation as the attached suture is pulled to fasten the anchor within the tissue. A fin at the proximal end of the anchor further increases the rotational leverage and expedites anchor fastening. When two or more anchors with connecting suture are delivered in series on a needle, the tension of the suture helps to draw the anchors together and approximates the pierced tissue.

Title: Audio coding system using spectral hole filling
Inventor: TRUMAN MICHAEL MEAD
IPC: H03M7/30
Filed: 2003-05-30
Granted: 2012-04-10
Abstract: Audio coding processes like quantization can cause spectral components of an encoded audio signal to be set to zero, creating spectral holes in the signal. These spectral holes can degrade the perceived quality of audio signals that are reproduced by audio coding systems. An improved decoder avoids or reduces the degradation by filling the spectral holes with synthesized spectral components. An improved encoder may also be used to realize further improvements in the decoder.

Abstract: Techniques are disclosed to limit short-term correlations associated with outputs of stream cipher keystream generators. Output values of a generator are paired such that the paired outputs are sufficiently far apart to be considered independent. In one described implementation, a method includes sequentially storing a plurality of results provided by a stream cipher output rule in a first, second, and third storage units. A pairing function pairs individual values from the first and third storage units that are at least a threshold value apart. Upon reaching the threshold value of the output rule results, the contents of the first, second, and third storage units are rotated serially.
