Title: Electronic article surveillance system with cancellation of interference signals
Inventor: FREDERICK THOMAS J
IPC: G08B13/24
Filed: 1997-05-09
Abstract: An electronic article surveillance system (100) includes a signal generator (22, 24, 26) for generating an interrogation signal (28) in an interrogation zone (30), an antenna (36) which receives a signal (34) present in the interrogation zone (30), and circuitry for cancelling interference. A hybrid interference component cancelling loop forms a digital interference estimate signal (108) which is converted (106) into an analog estimate signal, which is subtracted (102) from an input analog signal (40). The difference signal is digitized and subjected to additional digital interference cancellation processes (108). Each of the signal processing operations (108) entails performing a polyphase decomposition of a digital input signal, estimating a mean value of each of the resulting subsequences, and combining the estimated mean values to form an interference component estimate signal. An input sample window for a comb-filtering stage is phase adjusted relative to the interrogation signal to compensate for changes in phase of the marker signal (34).

Abstract: A switching mechanism interfaces a flexible shaft to the handle of a circuit interrupter which handle is rotated in a arcuate path between an on position and an off position. The switching mechanism includes a handle attachment for rotating between the on position and off position. The switching mechanism includes a base plate which is attached to the circuit interrupter and secures a flexible shaft thereto. The other end of the flexible shaft is connected to a remote, exteriorly mounted operating handle. The base plate has a perpendicularly extended tab with ears thereon which feeds through an opening in a portion of the linearly moving part of the handle mechanism actuator. Since the present apparatus is to be disposed on the side of the circuit breaker, there is a likelihood for sideways twisting or torsional rotation of the yoke in the direction perpendicular to the plane in which the arc of the handle of the circuit breaker is to move during opening and closing operations. The presence of the tab which captures the actuating mechanism between the ears thereof and the flat surface of the base prevents or greatly minimizes sideways twisting, torsion or rotation during the operation of the handle mechanism.

Patent CA-2268659-A1 (CA)
Title: Rectangular cathodic arc source and method of steering an arc spot
Inventor: GOROKHOVSKY VLADIMIR I
IPC: C23C14/24
Filed: 1999-04-12
Abstract: The invention provides an arc coating apparatus having a steering magnetic field source comprising a plurality of electrically independent closed-loop steering conductors disposed in the vicinity of the target surface, each steering conductor being controlled independently of the other steering conductors. Increasing the current through one steering conductor increases the strength of the magnetic field generated by that conductor relative to the steering conductor along the opposite side of the cathode plate, shifting the magnetic field on the opposite side of the cathode plate transversely. Selective unbalancing of the steering conductor currents thus increases the effective breadth of the erosion zone to provide more uniform erosion of the target surface. The steering conductors may be disposed in front of or behind the target surface of the cathode plate. In a further embodiment, groups of steering conductors are disposed along opposite sides of the cathode plate. By selectively applying a current through one conductor in each group, the path of the arc spot shifts to an erosion corridor defined by the active steering conductor. The invention also provides a plurality of internal anodes disposed within the plasma duct, for deflecting the plasma flow and preserving a high ionization level of the plasma. The invention also provides a magnetic focusing system which confines the flow of plasma between magnetic fields generated on opposite sides of the coating chamber. The plasma focusing system can be used to deflect the plasma flow off of the working axis of the cathode, to remove the neutral component of the plasma which otherwise constitutes a contaminant, by disposing the plasma focusing coils in progressively asymmetric relation to the working axis of the cathode, to deflect the flow of plasma along a curvate path toward a substrate holder. The invention also provides a shield at floating potential, restricting the cathode spot from migrating into selected regions of the target evaporation surface outside of the desired erosion zone. The shield may be positioned immediately above the region of the target surface in the vicinity of the anode, protecting the anode from deposition of cathodic evaporate and providing better distribution of cathodic evaporate over the substrates to be coated.
