Patent number: 7440172Abstract: An doped fiber optical amplifier featuring an optical component having first wavelength division multiplexer, an isolator and a second wavelength division multiplexer is described. The isolator supports the propagation of optical signals within a predetermined signal wavelength range in one direction. Pump signals having a wavelength within a pump wavelength range are diverted by the wavelength division multiplexers to inhibit coupling of the pump signals with the isolator. The optical amplifier supports the use of relatively high-powered optical pump lasers. The optical component is optically disposed between different lengths of doped fiber and serves to reduce optical noise within the amplifier.Type: GrantFiled: June 23, 2006Date of Patent: October 21, 2008Assignee: Viscore Technologies Inc.Inventor: Yunqu Liu

Patent number: 7428765Abstract: Passenger boarding bridges have adjustable walkways that are elevated high above the ground when servicing aircraft doorways. Passenger safety is improved by automatically stabilizing the passenger boarding bridge when it is in an aligned condition. A method for automatically stabilizing the passenger boarding bridge includes moving the aircraft-engaging end of the passenger boarding bridge into an aligned relationship relative to the doorway of an aircraft. The aligned relationship between the aircraft-engaging end of the passenger boarding bridge and the doorway of the aircraft is detected automatically. Adjustable jacks, which are fixedly mounted to the passenger boarding bridge wheel carriage, are actuated between a retracted condition and an extended condition. In the extended condition, the adjustable jacks engage a ground surface below the passenger boarding bridge, thereby increasing the stability of the passenger boarding bridge.Type: GrantFiled: November 4, 2005Date of Patent: September 30, 2008Assignee: DEW Engineering and Development LimitedInventor: Neil Hutton

Patent number: 7319788Abstract: The present invention relates to a method for visualizing ST data based on principal component analysis. ST data indicative of a plurality of local S spectra, each local S spectrum corresponding to an image point of an image of an object are received. In a first step principal component axes of each local S spectrum are determined. This step is followed by the determination of a collapsed local S spectrum by projecting a magnitude of the local S spectrum onto at least one of its principal component axes, thus reducing the dimensionality of the S spectrum. After determining a weight function capable of distinguishing frequency components within a frequency band a texture map for display is generated by calculating a scalar value from each principal component of the collapsed S spectrum using the weight function and assigning the scalar value to a corresponding position with respect to the image.Type: GrantFiled: May 7, 2003Date of Patent: January 15, 2008Assignee: Calgary Scientific Inc.Inventors: J.
