Patent CA-2173029-A1 (CA)
Inventor: MADSEN ROBERT C
IPC: B64F5/20
Filed: 1996-03-29
Abstract: An  apparatus  for  deicing  an  aircraft  is  defined by  an insulated shelter being a size capable of enclosing an aircraft.          The shelter is positioned on a deicing surface that absorbs heat from means such as electrical filaments or heated pipes within the deicing surface or through the application of infrared radiation onto the deicing surface.     In turn,  the deicing surface radiates heat into the air within the shelter.  Once an aircraft is enclosed within the shelter, infrared radiation is applied to a portion of the exterior surface of the aircraft.          The combination of the infrared radiation and the heat radiating from the deicing surface rapidly deices and substantially dries the exterior surface of the aircraft.   The exterior of the aircraft  is  subsequently  heated  to  a  sufficiently  high temperature that ice will not reform on the aircraft prior to take off.

Patent CA-2181430-A1 (CA)
Inventor: SHOEMAKER DONALD K
IPC: G01V3/10
Filed: 1996-07-17
Abstract: A system for detecting metal targets located in a background environment such as the ground evaluates metal targets by processing components of signals at two or more different frequencies. A component of the received signal induced by the ground can be eliminated by subtracting signal components measured at two different frequencies. The received signal can be processed to account for changes in the background response with frequency. The type of an unknown target can be identified by processing background excluded components to produce data characterizing the target type.

Inventor: KOTTKE WILLE
IPC: H04W88/02
Filed: 1996-11-18
Abstract: A battery (100) includes a latch (106) for easy attachment to a radio (402). Engagement of the battery (100) to the radio is accomplished via matching a plurality of retaining rails (110) via notches (112) with a plurality of opposing and complementary retaining rails on the radio (402). A simple sliding motion locks the latch (106) to the radio (402). Disengagement requires little force as the latch (106) is depressed in the same direction as the battery (100) is slid down. The battery comes to a stop when an alignment of the notches (112) with the radio retaining rails has taken place. An effortless lift separates the battery (100) from the radio (402).

Title: Mesh simplification and construction of progressive meshes
Inventor: HOPPE HUGHES H
IPC: G06T15/00
Filed: 1997-01-10
Abstract: An efficient, lossless, continuous-resolution representation (the "PM representation") of highly detailed geometric models for. computer graphics specifies a succession of progressively more detailed polygonal meshes (i.e., "progressive meshes") as a base polygonal mesh and a sequence of complete mesh refinement transformations (e. g., the vertex split transformation) that approximate the model at progressively finer levels of detail. Procedures for storing and transmitting geometric models using the PM representation address several practical problems in computer graphics: smooth geomorphing of level-of-detail approximations, progressive transmission, mesh compression, and selective refinement. An optimized mesh simplification procedure constructs the PM representation of a model from an arbitrary polygonal mesh, while preserving the geometry of the original mesh as well as its overall appearance as defined by its discrete and scalar appearance attributes such as material identifiers, color values, normals, and texture coordinates. In particular, the PM representation and these procedures preserve discontinuity curves such as creases and material boundaries of the geometric model.

Title: Polymeres a chaines laterales fluorocarbonees cristallisables, leurs monomeres, et substrats enduits de ces polymeres
Inventor: THOMPSON ROBERT M
IPC: C08F20/22
Filed: 1996-07-19
Abstract: L'invention se rapporte à des polymères présentant des groupes latéraux pendants de formule -(CH¿2?)¿m?-(CF¿2?)¿n?F dans laquelle m vaut 10 et n vaut au moins 10. Dans ces polymères, le monomère contenant la fraction -(CF¿2?)¿10?F constitue environ 50 % ou plus du pourcentage total de tous les monomères. Il a été découvert que, lorsque le nombre de groupes -CH¿2?- est maintenu à 10 et lorsque la distribution dans les groupes -(-CF¿2?)¿m?F est ajustée, la configuration particulière des groupes latéraux entraîne la formation de zones cristallines qui réduisent la mobilité des chaînes latérales et améliore ainsi l'imperméabilité des matériaux enduits des polymères selon l'invention.

Inventor: LEE HENRY J
IPC: D21F1/00
Filed: 1997-07-31
Abstract: A shed formation device with a frame assembly having at least two harnesses mounted for movement in the frame.   Each harness includes a plurality of heddles through which cross machine direction (CMD) yarns are passed.  The existing CMD yarns of the fabric pass over an out-feed bar mounted to the frame assembly as they exit the heddles.  A replacement CMD yarn supply provides replacement CMD yarns to the heddles for reweaving with the machine direction (MD) yarns to form seam loops and finished fabric ends.  The replacement CMD yarns pass over an in-feed bar, mounted to the frame assembly, prior to passing through the heddles.  The harnesses are manipulated to form an unweaving shed in the existing CMD yarns and re-weaving shed in the replacement CMD yarns.  Retractable expansion forks assist the unweaving and reweaving of the MD yarns.  A leasing device captures MD yarns from the unweaving shed and releases them into the reweaving shed to form seam loops and finished ends.
