Abstract: The present subject matter is directed to a system and method for detecting lifting of a ground brush of a generator of an electrical power system connected to a power grid so as to prevent damage to the electrical power system (e.g. bearing failure). The method includes monitoring, via at least one sensor, a voltage signal of a rotor shaft of the generator. The method also includes determining at least one characteristic (e.g. amplitude and/or frequency) of the voltage signal for a predetermined time period. Further, the method includes determining whether the at least one characteristic of the voltage signal is above a predetermined threshold, wherein the at least one characteristic of the voltage signal being above the predetermined threshold is indicative of the ground brush being lifted.

Abstract: A method of treating wool in the form of a fibre, yarn, sliver, fabric or garment. A polymer coating is applied by plasma polymerisation to prevent shrinkage due to felting due to laundering. The method may include a pre-treatment step, for example application of a continuous plasma of inert gas, application of nano particles to the fibre surface or coating the fibre surface with a polymer.

Abstract: A process for bonding insulated wires is provided wherein a conforming free air ball is formed from an insulated wire to create a ball bond. A tip of the insulated wire is first positioned close to an electronic flame-off device and a first electric discharge is produced from the electronic flame-off device to melt the tip of the insulated wire and produce a pilot ball. The electric discharge is then terminated. A second electric discharge is then generated to produce the conforming free air ball, and thereafter, the conforming free air ball is attached to a bonding surface to create the ball bond.

Abstract: Optical breakdown by predetermined laser pulses in transparent dielectrics produces an ionized region of dense plasma confined within the bulk of the material. Such an ionized region is responsible for broadband radiation that accompanies a desired breakdown process. Spectroscopic monitoring of the accompanying light in real-time is utilized to ascertain the morphology of the radiated interaction volume. Such a method and apparatus as presented herein, provides commercial realization of rapid prototyping of optoelectronic devices, optical three-dimensional data storage devices, and waveguide writing.

Abstract: A system providing methods for indirect access control is described. When an attempt to access a network by a first application is detected, a determination is made as to whether at least one other application is attempting indirect network access through the first application. If at least one other application is determined to be attempting indirect network access, each such other application is evaluated to determine if it is approved for network access. If each such other application is approved for network access, access to the network is permitted. Otherwise, access to the network is denied.

Abstract: An apparatus and method for applying adhesive to the open ends of containers having oppositely disposed front and rear wall panels, oppositely disposed side panels, and a center line parallel to the front and rear wall panels and aligned with the center of the side wall panels. The apparatus includes a conveyor for moving the containers along a line of movement through an adhesive application area. The containers are substantially immovably supported during adhesive application procedures. A pair of rotary adhesive applicators apply adhesive to the edges and portions adjacent such edges of an open end of the containers. These rotary adhesive applicators each have a central axis which is oriented in a non-normal relationship to at least one of the center line and line of movement of such containers, and are arranged relative to the conveyor such that as the containers pass the applicators, such applicators contact the edges of an open end of the container panels.
