Abstract: An anti computer virus program uses a library of virus drivers that includes an indication of whether a particular virus can cause irreparable damage and data indicating enhanced user warnings and actions that might be associated with such viruses. If a detected computer virus is one that can cause irreparable damage, then an enhanced user warning (16) is issued indicating this to the user and a notification (28) of the possibility of such corruption is added into the repaired computer file. The notification may take the form of an electronically signed (30) banner message or the like.

Abstract: A massage apparatus comprises a support structure, a plurality of massaging arms operatively connected to the support structure, and an actuating mechanism. Each massaging arm has at least one massaging finger adapted to impart a massaging force to a user. Each massaging arm is moveable relative to the support structure in a manner to move its corresponding massaging finger relative to the support structure between a rearward position and a forward position. The actuating mechanism is adapted to engage the massaging arms in a manner to sequentially move the massaging fingers between their rearward and forward positions.

Abstract: A partially submergible, covered trailer for launching and landing watercraft from the sides or the rear of the covered trailer. The covered trailer includes a lower shell and an upper shell formed to mate with one another. The lower and upper shells define an interior for receiving and retaining personal watercraft. The upper shell is permitted to move between an elevated position and a lowered position relative to the lower shell. While the upper shell is in the elevated position, access is provided to the interior of the covered trailer from the rear and sides of the covered trailer.

Abstract: Disclosed is a process for producing polyolefins wherein the solids are conveyed by a gas throughout the polymerization process, thereby resulting in improved operability.

Abstract: A novel process for producing homopolymers and interpolymers of olefins which involves contacting an olefin and/or an olefin and at least one or more other olefin(s) under polymerization conditions with a metallocene catalyst and dinitrogen monoxide in amounts sufficient to reduce the electrostatic charge in the polymerization medium. Also provided is a process for reducing electrostatic charge in the production of polyolefins by introducing dinitrogen monoxide into the polymerization medium.

Abstract: An endoluminal prosthetic device comprising axially repeating rings made up in turn of unit cells. The unit cells themselves are made up of circumferentially repeating patterns of multilayered strut members to form the ring. The rings may be axially connected to form a stent or an expandable housing for housing other medical device inserts. The multilayered struts, created by recessed slots cut from various regions in the strut members, permit improved radiopacity, increased flexibility during insertion stage into a lumen and better post-expansion conformability to the longitudinal shape of the body lumen, while providing increased rigidity and strain tolerance once the device has been expanded, as well as improved expansion ratio and fatigue characteristics. Variations on slot placement, length, orientation and shape with respect to the centerline of the strut members permit the optimization of a stent's strength, rigidity, strain and related mechanical properties.

Abstract: A novel process for producing homopolymers and interpolymers of olefins which involves contacting an olefin and/or an olefin and at least one or more other olefin(s) under polymerization conditions with a Ziegler-Natta catalyst and dinitrogen monoxide in an amount sufficient to reduce the electrostatic charge in the polymerization medium. Also provided is a process for reducing electrostatic charge in the polymerization of an olefin by adding dinitrogen monoxide.

Abstract: A method, apparatus, and article of manufacture for using a relational database management system to support on-line analytical processing (OLAP) systems. A multi-dimensional database is defined having a set of multi-dimensional data blocks and a set of identifiers comprising selected dimensions of multi-dimensional data for identifying particular ones of the multi-dimensional data blocks. The set of identifiers provides an ordering of the multi-dimensional data blocks using multi-dimensional member identifiers and holds usage information and age information about the multi-dimensional data blocks. The data in the set of multi-dimensional data blocks is stored in a relational database that represents the multi-dimensional database. Then, a set of rows representing a multi-dimensional data block is accessed from the relational database.

Abstract: Disclosed is a method for controlling or reducing the amount of powder fines present in a polyethylene fluidized bed reactor. The method uses hydrocarbons that are inert with respect to the polymerization reaction, as well as using reactive olefins. The reduction of powder fines provides significant operating benefits in the fluid bed process, including reduced formation of powder agglomerates in the reactor and reduced fouling of equipment in the recycle gas stream.

Abstract: An apparatus for detecting an invisible, near infrared fluorescing mark disposed on a background comprises: includes an excitation source for exciting the mark, having sufficient power to excite the mark and provide a fluorescent signal the mark from a; a signal detector for detecting the fluorescent signal from the mark; a and power modulator means for varying the power if the excitation source between zero and the maximum power level to produce a decodable fluorescent signal from the mark disposed on the background. A process for decoding an invisible mark having a near infrared fluorescing material includes the steps of: providing at least one invisible, near infrared fluorescing mark disposed on at least one portion of a background; exciting the mark with a laser having a maximum power level sufficient to provide a fluorescent signal from the mark; detecting the fluorescent signal and concurrently varying the power of the laser between zero and its maximum power, to obtain a decodable fluorescent signal.

Abstract: This invention provides an accessory for an automatic pool cleaner, to increase the randomness of movement of a suction head of the pool cleaner, and a method therefor. The method comprises looping a section of the cleaner hose and allowing the hose sections leading up to the loop to vary in length. Particularly, the hose section leading from the pump to the loop is varied. The accessory comprises two connection parts, one for connection to each respective section of hose to form the necessary hose loop. Preferably one of the parts is slidable along the hose length to enable the hose to vary its length. The sliding action of the hose occurs between two stops in the length of the hose, and a pawl mechanism is provided to enable the slide to occur in one direction towards a stop. Contact with the stop causes the pawl mechanism to switch over and slide the hose in the opposite direction.

Abstract: A method and apparatus for monitoring the behavior over time of a distributed system. Time-stamped data descriptive of events at one subsystem are placed into a local buffer. The subsystem is notified of the time when a trap condition occurs at another subsystem. Data having a time-stamp within a certain interval of the occurrence of the trap condition are archived to provide a history of the system for later analysis. Time is determined by a local clock in each subsystem. These clocks are synchronized to ensure accurate correlation between events at different subsystems. Trap conditions are categorized and data descriptive of subsystem states are classified to facilitate selective notification of one or more other subsystems, and selective retention of the data, depending on which category of trap condition has occurred and which class of data has been collected.
