Title: Method for temperature compensation in an image sensor
Inventor: DUCOURANT THIERRY
IPC: H04N5/359
Filed: 2000-12-28
Granted: 2008-11-18
Abstract: The invention concerns a method for temperature compensation in an image sensor comprising photosensitive points (O1 to O6, R1 to R9) sensitive to room temperature, each connected to a line conductor (Y1 to Y3) and a column conductor (W1, W2, Z1 to Z3). Each of the photosensitive points is connected by one of its conductors to a reading circuit (30a, 30b). The photosensitive points are divided into sensing photosensitive points (R1 to R9) designed to be exposed to a light information translating the image to be detected, the reading circuits (30b) associated with said photosensitive points delivering each a measurement voltage representing the image to be detected and into blind photosensitive points (O1 to O6) protected from the light information, the reading circuits (30a) associated with said blind sensitive points delivering each a darkness voltage enabling temperature compensation. When an image is detected, the method consists in collecting darkness voltages derived from one or several detected images and in using the average correction value to generate a correction voltage (VDR) to be applied, when a subsequent image is detected, to the reading circuits (30b) associated with the sensing photosensitive points (R1 to R9) so that they deliver a substantially temperature-independent measurement voltage. The invention is particularly applicable to radiological image detectors.

Abstract: An EAS marker has a paintable or printable bias magnet material (56), which is either directly painted onto the EAS marker (55,65) or first placed onto a substrate material (58), which is then placed into the EAS marker. The material includes a magnetic powder mixed with resin and solvent. This "bias paint" is then applied onto the EAS marker. The magnetic powder, resin, and solvent provide a very dense layer after drying, which has a magnetic material density that is usually lower than a rolled product, but is higher than that of the injection-molded magnet material. Printing the bias magnet allows nondeactivatable magnetomechanical EAS markers to be made using web-based mass production methods.

Title: Downhole actuation system utilizing electroactive fluids
Inventor: GOODSON JAMES E JR
IPC: E21B33/1295
Filed: 2002-07-19
Granted: 2007-06-12
Abstract: Downhole wellbore tolls (14) are actuated by electrically controllable fluid s energized by a magnetic field for example. When energized, the viscosity sta te of the fluid may be increased by a degree depending on the fluid formulation . Reduction of the controllable fluid viscosity by terminating a magnetic fiel d acting upon the fluid may permit in situ wellbore pressure to display a tool actuating piston (16). Displacement of the tool actuating piston (16) is prevented by the controllable fluid in a viscous state. The viscous sate of the fluid is energized by a magnetic field environment. When the field is de - energized, the controllable fluid viscosity quickly falls thereby permitting the fluid to flow through an open orifice (40) into a low pressure receiving volume (36). In an alternative embodiment of the invention, an expandable volume fluid may be used against a slip actuating element in the same manner as a fluid pressure motor. A magnetic field, aligned to act upon the controllable fluid, causes the fluid to volumetrically expand and thereby display a slip actuating piston.

Title: Anvil bridge stent design
Inventor: BONSIGNORE CRAIG
IPC: A61F2/84
Filed: 2004-03-04
Granted: 2011-09-20
Abstract: A stent or other intraluminal medical device may be constructed utilizing a series of anvil bridges interposed between a series of fixed bridges to reduce the likelihood of deformation during stent loading and stent deployment without sacrificing overall stent flexibility. The stent comprises a plurality of hoops interconnected by a plurality of fixed bridges. The stent also comprises a plurality of anvil bridges, which transmit forces only when the stent is subjected to compressive axial loading. The stent may also comprise markers formed from housings integral with the stent and marker inserts having a higher radiopacity than the stent. This design provides for more precise placement and post-procedural visualization in a vessel, by increasing the radiopacity of the stent under X-ray fluoroscopy. The housings are formed integral to the stent and the marker inserts are made from a material close in the galvanic series to the stent material and sized to substantially minimize the effect of galvanic corrosion. The housings are also shaped to minimize their impact on the overall profile of the stent.

Abstract: A thrust absorber (130) is interposed between a thrusting means (80) and an anchoring means (60) that cooperate to axially displace another member (30). The thrust absorber (130) includes an enclosure (64) fixed to the anchor mea ns (60) and a retainer (62) connected to the thrusting means (80). A biasing member (136) is operably associated with the retainer (62).
