The filtration media includes an effective amount of a germicidal chemically grafted and covalently bonded to a surface of the media. The germicidal grafted filter media is prepared by contacting the media with a grafting solution comprising an anionic monomer, a catalyst, a graft initiator and a germicide and subsequently curing tile media at an elevated temperature to chemically graft a polymerized salt of the polymerizable anionic monomer and the cationic germicide onto a surface of the media. Filter media suitable for use in the present invention include ceramic spheroids, hollow glass spheres, polymeric type media and thermoset coated glass spheres.

Abstract: A method for use with a plasma immersion ion implantations systems wherein a substrate W having a patterned photoresist P thereon is implanted. The method includes ionizing a first gas in a chamber 12 to produce electrically inactive ions and reacting the electrically active ions with the photoresist P to produce outgassing 64. The outgassed material 64 is continuously evacuated until outgassing is substantially completed. The method further includes ionizing a second gas to produce electrically active ions and implanting a positively charged species of the electrically active ions into the substrate. Also disclosed is a method for curing the photoresist prior to ion implantation. A gas is ionized in the chamber 12 to produce positively and electrons. The electrons are first attracted to a substrate in the chamber having patterned photoresist P thereon for hardening the photoresist. The positively charged ions are then implanted into substrate W wherein photoresist outgassing is substantially prevented.

Abstract: Building histograms by using feedback information about the execution of query workload rather than by examining the data helps reduce the cost of building and maintaining histograms. A method of maintaining self-tuning histograms updates histograms based on feedback about the execution of a user query. A histogram may be initialized using an assumption of uniform distribution of data or by combining existing histograms. A histogram tuner accesses and estimated result in response to a user query generated by using the histogram. The histogram tuner calculates an estimation error based on the result of the user query and the estimated result. The frequencies of histogram buckets are refined based on the estimation error. The bucket bounds of the histogram are restructured based on the refined frequencies. The method may be performed on-line after a user query or off-line by accessing a workload log.

Abstract: A Hall effect safety switch assembly for de-activating a motor vehicle if a user is not positioned on a vehicle seat. The assembly includes a switch frame for mounting the assembly, a magnet and a hall effect sensor mounted to the switch frame in a spaced apart relationship, and a vane that moves in response to the presence of a vehicle operator on the seat that causes the Hall effect sensor to provide an inhibit signal that prevents an engine from running.

Abstract: A keyboard supporting member has a generally planar keyboard support surface whose orientation is adjustable. A keyboard engaging member defines aligned incline defining slots on opposite sides of a center section. A second, workstation engaging member allows the user to move the keyboard back and forth with respect to a workstation. This allows the user to move the keyboard between a storage position and an in use position. A linkage interconnects the two members for adjusting a relative position of the keyboard engaging member with respect to the workstation engaging member thereby allowing the keyboard position and orientation to be controlled by the user. The linkage includes a first elongated member having one end rotatably mounted to the workstation engaging member which has an arcuate slot at one end spaced from the end that is connected to the workstation engaging member.

Abstract: In one exemplary embodiment the invention provides a data mining system for use in finding cluster of data items in a database or any other data storage medium. A portion of the data in the database is read from a storage medium and brought into a rapid access memory buffer whose size is determined by the user or operating system depending on available memory resources. Data contained in the data buffer is used to update the original model data distributions in each of the K clusters in a clustering model. Some of the data belonging to a cluster is summarized or compressed and stored as a reduced form of the data representing sufficient statistics of the data. More data is accessed from the database and the models are updated. An updated set of parameters for the clusters is determined from the summarized data (sufficient statistics) and the newly acquired data. Stopping criteria are evaluated to determine if further data should be accessed from the database.

Abstract: A pig for evacuating pipelines is disclosed. The pig includes a body of a deformable material having an outer surface configured to contour to a pipeline to be evacuated. At least a portion of the deformable material is impregnated with a quantity of magnetic or magnetizable metallic particals.

Abstract: An over the highway vehicle having an occupant restraint system is disclosed. An improved harness for retaining an occupant in a bunk is also disclosed. The harness is connected to a bunk by a buckle and hinge arrangement. A frangible connection between an upstanding leaf of the hinge is provided which fails due to forces applied to the harness as a result of a collision. The system includes an occupant restraining strap and a buckle having a component attached to the strap and a mating component attached to the vehicle for releasably connecting the strap to the vehicle at a buckle location. An anchor securer the strap to the vehicle at a location spaced from the buckle location.

Abstract: A filtering apparatus including a fluid monitoring head and a replaceable filter cartridge removably fastened to the head. The fluid monitoring head includes a shut off mechanism for interrupting fluid flow through the cartridge when a predetermined quantity of fluid has been treated by the filter. The filter cartridge is releasably coupled to the shutoff mechanism when the filter is installed. The shut off mechanism includes a valve element carried by a shaft that forms part of a driven member forming part of the monitoring head. A biasing element exerts a force on the valve element carrying shaft tending to move the valve to a flow blocking position. The shaft engages a keeper or hold off element threadly retained in the filter cartridge. As the driven member rotates, the keeper element is gradually unthreaded until it separates from the filter cartridge, allowing the force of the biasing element to move the valve member into a flow interrupting position.

Abstract: A method of making a wire braid shrouded annularly corrugated metal tube. An annularly corrugated metal tube is formed. A braided wire shroud is placed around the annularly corrugated metal tube. The braided wire shroud is deformed into a corrugation valley of the annularly corrugated metal tube so that the shroud conforms to the adjacent peaks and the intervening valley. The annularly corrugated metal tube and the braided wire shroud are severed at a desired location between the corrugation peaks. The shroud is then bonded to the tube adjacent the end of the shrouded tube.

Abstract: A flexible metal conduit is disclosed that comprises a thin metal ribbon arranged in a helix about a longitudinal axis. Convolutions of the helix are disposed adjacent each other with the ribbon defining helical, sinuously corrugated inwardly and outwardly facing conduit surfaces forming radially inner and radially outer apices that are spaced substantially evenly apart and extend parallel to the convolution edges. A first ribbon edge region is defined by a partial corrugation and a flange extending radially from the partial corrugation. A second ribbon edge region is defined by a second partial corrugation and a second flange extending radially from the second partial corrugation. The first and second partial corrugations abut to form a helical seam running along the convolution junctures. The first and second edge flanges abut at the corrugation seam and are interlocked to secure the convolutions together.
