Title: A bar code reader
Inventor: ISHII KAZUO
IPC: G06K7/14
Filed: 1997-10-31
Granted: 2001-04-03
Abstract: A fragmentary pulse width data train extractor 3 scans a bar code label on a moving article with a scan beam projected onto the bar code label, receives the reflection of the scan beam, converts the reflected beam into an electric signal, and extracts only pulse width data trains corresponding to black and white bars constituting a bar code on the basis of the pulse width of the electric signal as fragmentary pulse width data trains.  A synthesizing unit 4 synthesizes a complete bar code pulse width data train from the extracted fragmentary pulse width data trains on the basis of position data of data pieces in the data trains, and outputs the complete bar code pulse width data train.  A decoding unit 5 converts the complete bar code pulse width data train from the synthesizing unit into numerals, characters, etc.  An outputting unit 6 outputs the result of the conversion to an external apparatus.

Title: Refrigerator door seal assembly
Inventor: JEZIOROWSKI LES
IPC: F25D23/08
Filed: 1998-03-05
Granted: 2004-07-06
Abstract: A refrigerator has French doors with vertically extending confronting side walls. At least one of the confronting side walls has a movable sealing gasketing member adapted to sealingly engage the other confronting side wall when the doors are in a closed position. The doors move between an open position and into the closed position through a temporary intermediate partially closed position. In the partially closed position the doors extend over the refrigerator compartment with temporary non-sealing vertically extending portions of the confronting side walls of the doors spaced apart from one another a predetermined gap distance. A first set of magnets are positioned in the doors at least along the temporary non-sealing vertically extending portions of the confronting side walls. The first magnets have a magnetic field attraction strength insufficient to move the gasketing member across the predetermined gap distance and sufficient to seal the gasketing member to the other confronting side wall when the predetermined gap distance is reduced. A second set of magnets have a magnetic field strength greater than the first magnets. The second magnets are positioned in at least one location along each of the confronting side walls to trigger local movement of the gasketing member towards the other confronting side wall locally reducing the predetermined gap. This triggers the first magnets to move the gasket along the vertically extending portions into sealing engagement with the other side wall. In the preferred embodiment the second magnets are located as a continuation of and in alignment with the first magnets. Swiping of the confronting side walls of the doors is limited at the second magnets.

Abstract: An electrosurgical instrument primarily intended for so-called "underwater"  electrosurgery has a radio frequency generator, a handpiece, and an electrode assembly detachably mounted to the handpiece.  Different electrode assemblies may be selected according to the surgical procedure to be performed. To adapt the generator characteristics for improved electrosurgical performance, each electrode assembly contains an identification element such as a capacitor of unique value which is sensed by the generator. Inside the generator, the sensed capacitor value causes the selection of operating parameters, preferably a nominal generator output power and a peak voltage limit, to suit the selected electrode assembly.

Abstract: A water-immiscible marker is dissolved in polyethylene glycol or other suitable carrier, and the marker so dissolved is added to a waterborne composition which is used as an additive to a waterborne or water processable composition. Subsequently, the marker is either extracted with a non-polar solvent or detected by means of a surface spot test. From the non-polar solvent, the marker is extracted with an acidic aqueous solution or an alkaline aqueous solution, depending upon the marker, and color-developed. Likewise, a surface spot test can detect the presence of the marker by, if necessary, first softening the marked surface to be tested either chemically or by thermal means, and developing a color with a color-developing reagent placed on the exposed surface. Applications can include the marking of paint, coatings, wax emulsions and water soluble/dispersable additives commonly used in water based applications, e.g., cement additives.

Abstract: A communication plug that generates crosstalk that complements the compensating crosstalk in a legacy jack or connector. The communication plug includes a dielectric carrier on which a plurality of electrical conductors are disposed. Each conductor is configured to wrap around a first end of the carrier thereby forming a series of adjacent inductive loops. Complementary crosstalk is generated between the conductors as a result of the fields created from current flow through the inductive loops and can be fixed to a desired level by modifying certain engineerable parameters. The inductive loops are positioned in the nose or front region of the plug where the conductors engage the jack spring wires or terminals thus minimizing the propagation delay between the crosstalk signals generated in the plug and the crosstalk signals generated in the jack or connector.
