Title: Balloon dissectors
Inventor: JERVIS JAMES E
IPC: A61B19/00
Filed: 1996-12-11
Abstract: A balloon (1000) formed from first and second sheets of a material has one or more outwardly extending horns (1001) formed in a distal region of the balloon. The material used to fabricate the balloon is preferably substantially inelastic over the range of inflation pressures used to inflate the balloon. When the balloon is in a deflated condition, the horns may be folded inwardly, into the interior space of the balloon, to provide a balloon which may easily be rolled, folded, or otherwise gathered into a compact package. Upon inflation, the horns evert and extend outwardly beyond the distal end of the balloon. Another embodiment is an economical balloon dissection apparatus having a balloon (952) with an elongated neck (960). The neck may be inverted to provide a space in the closed neck to receive a rod (951) or other tunneling member. A tubular member (990) having a bore sized to receive a laparoscope may be inserted into the balloon neck in place of the rod if visualization is desired. A variation includes a reusable handle (954) and tunneling rod (990). The rod (990) may be inserted into the tubular member (991) disposed within the inwardly folded elongate neck and releasably latched within the tubular member.

Title: Optic device for detection of characteristics of particles in movement
Inventor: SCHANEN ISABELLE
IPC: G01N15/02
Filed: 1996-01-11
Abstract: The device uses the Doppler effect principle of laser velocity measurement. It comprises optical emission and reception guides formed by optical integration techniques on a single substrate (12), preferably glass. The emission guides, connected to a light source (3) produce two mutually coherent beams (1, 2) whose inclination from one another (A) is such as to constitute interference fringes in a measurement region (P) external to the substrate. The reception guides transmit to a detection and processing circuit (11, 9) the light refracted by the passage of particles across the measurement region. The substrate (12) is mounted on a support (15) installed in the orifice of a wall (16) along which flows the fluid transporting the particles to be examined. The substrate (12) comprises a plane (17) that is in contact with the fluid. This device facilitates determining the speed, size and/or number of moving particles in a fluid being displaced along a wall (16).

Title: Method and system for addressing lcd including mim diodes
Inventor: BOER WILLEM DEN
IPC: G02F1/1365
Filed: 1998-09-08
Abstract: A system and method for driving a thin film diode (TFD) inclusive AMLCD or imaging device (e.g. x-ray imager) includes providing each pixel with a pair of select lines and a single data line. Drive schemes are provided which increase the circuits tolerance for spatial and temporal variations in diode (e.g. MIM diode) characteristics, improve response time, increase the circuit's tolerance for RC delays on data lines, and reduces the potential for crosstalk or image retention. In certain embodiments, where each pixel includes a pair of select lines, and a single data line, the select voltage on the first select line alternates between V s + V offset and V s - V offset for subsequent frames, while the select voltage on the other select line alternates between -V s + V offset and -V s - V offset for subsequent frames, thereby allowing voltage at the common node to be added to the data voltage. Drive schemes herein are used in conjunction with row inversion driving of pixel arrays, and some embodiments are also compatible with column inversion, frame inversion, and/or pixel inversion.

Abstract: L'invention porte sur un procédé par échange d'ions permettant de charger et de répartir uniformément des métaux nobles dans un substrat catalyseur comprenant une zéolite pour produire un catalyseur de reformage non acide, monofonctionnel. Le substrat catalyseur est mis en contact avec une solution de charge aqueuse comprenant des cations de métaux nobles et non nobles. La solution de charge est formulée de sorte que les équivalents des cations de métaux non nobles restant dans le catalyseur, non liés ioniquement avec la zéolite lorsque la charge est complète, représentent 1,2 à 6 fois les équivalents des cations de métaux non nobles déplacés de la zéolite lors de l'échange ionique des cations de métaux nobles dans la zéolite, et simultanément le pH résultant de la solution de charge est compris entre 10,0 et 11,5. Le rapport requis 1,2 à 6,0 est obtenu lorsque le rapport des moles des cations des métaux non nobles ajoutés à la solution de charge aux moles des métaux nobles ajoutés à la solution de charge est compris entre 1 et 10. L'utilisation d'un procédé par échange d'ions permet d'obtenir des catalyseurs de zéolite renfermant moins de matières restant dans les micropores de la zéolite.
