Publication number: 20080158568Abstract: An interferometer includes a resonant cavity having a movable mirror and at least one fiber optic component acting as a fixed mirror. A surface of the fiber optic component is coated with a reflective film. An actuator is coupled to the movable mirror, such that when a scattered optical beam is coupled to the cavity, interference occurs between the surface of the fiber optic component coated with reflective film and a surface of the movable mirror facing the surface of the fiber optic component coated with reflective film. The reflective film on the surface of the fiber optic component causes closely spaced spectral lines within the scattered optical beam to be suitably resolved.Type: ApplicationFiled: March 7, 2008Publication date: July 3, 2008Applicant: GENERAL ELECTRIC COMPANYInventors: Glenn Scott Claydon, Ayan Banerjee, Shivappa Ningappa Goravar, Renato Guida, David Cecil Hays, Dirk Lange, Boon Kwee Lee, Sandip Maity, Long Que, Anis Zribi

Patent number: 6668627Abstract: A magnetically excited, resonant cantilever sensor apparatus has a cantilever as the transducer element. A static magnetic field is directed in the plane of the cantilever(s) cooperating with a current loop in/on the latter. Orienting the magnetic field along or perpendicular to the cantilever axis and controlling the current apprpriately allows for selective excitation of resonance or non-resonance modes and/or in a self-oscillation mode. The deflection of the cantilever is detected using piezoresistive or magnetic readout. The apparatus may be used as gas sensor, scanning force microscope, mechanical filter, temperature sensor or the like.Type: GrantFiled: October 1, 2001Date of Patent: December 30, 2003Assignee: Swiss Federal Institute of Technology ZurichInventors: Dirk Lange, Christoph Hagleitner, Oliver Brand

Patent number: 6520300Abstract: The invention relates to a method for regulating the brake(s) of an escalator or moving walkway, independently of the load. According to the invention, actual values are supplied to at least one regulator which contains at least one nominal value, the regulator intermittently performs a comparison between the nominal and actual values and controls at least one brake magnet using these values. The brake magnet or magnets in turn regulate(s) the brake(s) in such a way that a predeterminable linear braking deceleration can be achieved, whereby nominal values, in particular, in the form of several temporary deceleration values, are stored in the regulator in nominal value fields or nominal zones.Type: GrantFiled: January 28, 2002Date of Patent: February 18, 2003Assignee: Kone CorporationInventors: Ludwig Balzer-Apke, Dirk Lange, Sascha Neumann, Alexander Pietz

Patent number: 6273234Abstract: The invention relates to a method for load-independently braking the step or pallet belt of an escalator or a moving walkway. According to said method, the activation of at least one safety element triggers at least one frequency converter in such a way as to activate a time-dependent braking ramp, said frequency converter interacting with the drive motor. The braking ramp then slows down the step or pallet belt to 0 m/s with essentially constant deceleration.Type: GrantFiled: July 28, 2000Date of Patent: August 14, 2001Assignee: Kone CorporationInventors: Ludwig Balzer-Apke, Dirk Lange
