Title: Device for treating constriction in a bodily conduit
Inventor: LIPRIE SAMUEL F
IPC: A61F2/958
Filed: 1995-03-31
Abstract: This invention is an apparatus and method for treating an occlusion or constriction, such as a stenosis in a blood vessel  or  other  conduit  in  the  body,  as  well  as  an apparatus and method for treating a tumor or cancerous area occurring around a conduit or duct in the body.   The apparatus  includes  a  catheter  provided with  a  ribbed balloon encircling a portion near its distal end.   When inserted into the body over a guide wire and transported to the site of the stenosis, the balloon is inflated one or more times and, due to the ribbed balloon, blood perfuses around the catheter during the treatment.  A radio active source of material is inserted through the catheter to the site of the stenosis or cancer where it is maintained in position for a period of time to reduce the occurrence of re-stenosis or cancer.   A guide wire provided with a removable core can be utilized to properly maneuver the catheter to the site of the stenosis or cancer.

Abstract: A shipping tray for bottles or other such fragile vessels suitably containing liquids therein employs a two-sided configuration with bottle receiving cradles and top and bottom stop members to prevent the bottle from sliding out of the tray.  Shock absorbing members are provided about the perimeter of the tray, as well as a perimeter groove. Indentations at spaced locations on the tray perimeter function as shock absorbing spring members, and further allow displaced air to escape as the tray is lowered into a close fitting carton.  The indentations further provide grip access to enable easy removal of a tray from within a close fitting carton.  Both sides of a tray are functional, such that a series of trays may be packed with bottles with the trays in top side up or bottom side up configurations.  A stack of trays nest together when not in use, for compact storage.  When configured to receive wine bottles, the tray accepts multiple bottle shapes therein with adequate protection to each bottle style.  The tray includes depressable stop members, which may be removed or depressed out of the plane of the bottle, to provide a longer bottle receiving portion.  Multiple bottle configurations are thereby accommodated.

Patent CA-2218939-A1 (CA)
Inventor: VLADYMIR BARCHUK
IPC: G07D7/026
Filed: 1997-10-22
Abstract: A device for validating the authenticity of a document uses changes in capacitance due to the presence of an electrically conductive security thread extending across the document. The device uses a drive arrangement for moving of a document such as a bank note, past a sensing arrangement which senses changes in capacitance due to movement of a security thread therepast. A frequency generator produces a high frequency time varying oscillator signal and provides this signal to an elongate oscillator electrode extending across the path of movement. A lead elongate measuring electrode is electrically conductive and positioned in front of the oscillator electrode and extends across said path and a trailing elongate measuring electrode is positioned behind the oscillator electrode and extends across the path. The signals from the measuring and the oscillator electrode are provided to a signal processing arrangement. The signal processing arrangement processes the signals relative to detect a phase shift between the signals caused by a conductive security thread passing by the electrodes. Sensing of the phase shift reduces sensitivity to variations caused by wobble of the bank note and changes in separation distance of the bank note from the sensor.

Title: Improved location based paging for mobile telephone units
Inventor: HANSON ROBERT JOSEPH
IPC: H04W68/04
Filed: 1997-10-29
Abstract: An arrangement for paging mobile telephone units (MTU) in a cellular mobile system that conserves paging resources.  If the identity of the most recent cell in which the MTU was located matches the identity of the cell wherein the MTU was location on the previous registration, then an initial page covering only the cell of the most recent call location for the target MTU, and the neighboring cells for that cell, is used.  Advantageously, since the likelihood that the MTU is still within that cell or its neighbors is high, so that paging resources are conserved by paging in only a small number of cells.
