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

Publication number: 20060034569Abstract: The invention provides novel “folded” Mach-Zehnder interferometers (“folded” MZI's), methods for making folded MZI's, and systems and devices incorporating them. The novel folded MZI's are elaborated from conventional MZI structures by cutting across the interferometer arms of a conventional MZI structure and creating reflectors on the exposed ends of the interferometer arms to form two “folded” MZI's from a single conventional Mach-Zehnder interferometer structure. The novel folded MZI's show promise as sensors having a reduced size and enhanced sensitivity relative to sensors incorporating conventional Mach-Zehnder Interferometers.Type: ApplicationFiled: August 11, 2004Publication date: February 16, 2006Inventors: Min-Yi Shih, Christopher Kapusta, Todd Tolliver, Renato Guida, Samhita Dasgupta

Patent number: 6883774Abstract: A microvalve and a method of forming a microvalve. The microvalve comprises first and second layers, a diaphragm member and a switching means. The first and second layers are secured together to form a valve body that forms an inlet opening for receiving fluid, an outlet opening for conducting fluid from the valve body, and a flow channel for conducting fluid from the inlet to the outlet. The diaphragm is disposed between the layers, and is movable between open and closed positions. In these position, the diaphragm, respectively, allows and blocks the flow of fluid from the inlet to the flow channel. The diaphragm is biased to the closed position, and moves from the closed position to the open position when the pressure of fluid in the inlet reaches a preset value. The switching means is connected to the valve body for moving the diaphragm to the closed position against the pressure of fluid in the inlet.Type: GrantFiled: October 21, 2002Date of Patent: April 26, 2005Assignee: Lockheed Martin CorporationInventors: Matthew C. Nielsen, Laura J. Meyer, Todd G. Wetzel, Stanton E. Weaver, Jeffrey B. Fortin, Renato Guida

Publication number: 20050053346Abstract: A method of forming a waveguide including a core region, a cladding region, and an index contrast region situated therebetween includes depositing a polymerizable composite on a substrate to form a layer, patterning the layer to define an exposed area and an unexposed area of the layer, irradiating the exposed area of the layer, and volatilizing the uncured monomer to form the waveguide, wherein the polymerizable composite includes a polymer binder and sufficient quantities of an uncured monomer to diffuse into the exposed area of the layer and form the index contrast region. The resulting waveguide includes an index contrast region which has a lower index of refraction than that of the core and cladding regions.Type: ApplicationFiled: September 9, 2003Publication date: March 10, 2005Inventors: Kung-Li Deng, Thomas Gorczyca, Renato Guida, Matthew Nielsen, Min-Yi Shih, Todd Tolliver

Patent number: 6830229Abstract: A two-stage valve for controlling the flow of fluid from a pressurized fluid supply with an upper main body including a cavity with a contoured inner surface; a lower main body with at least one flow exhaust passage forming a primary flow path through the two-stage valve; a pre-stressed diaphragm sandwiched between the upper and lower main bodies, and pressure control capability for controlling the pressure in the cavity. A first valve opens and closes the flow of gas from the pressurized gas supply to the cavity. A second valve allows the pressure in the cavity to exhaust to the environment. Raising and lowering of the pressure in the cavity causes the pre-stressed diaphragm to open and close the flow of gas from the pressurized gas supply through the primary flow path of the two-stage valve. The design is suitable as a microvalve using Micro-Electro-Mechanical Systems (MEMS) concepts.Type: GrantFiled: February 28, 2003Date of Patent: December 14, 2004Assignee: Lockheed Martin CorporationInventors: Todd Garrett Wetzel, Mathew Christian Nielsen, Stanton Earl Weaver, Jr., Renato Guida, James Wilson Rose, Laura Jean Meyer

Patent number: 6774539Abstract: An actuator for applying an actuating force through a total displacement. The actuator includes: an actuator body; n piezo members supported by the body where n is an integer greater than or equal to two, each of the piezo members generating a force and a displacement upon application of a voltage thereon; and n−1 levers rotatably disposed in the body and each having first and second ends corresponding to two of the n piezo members such that the displacements of the n piezo members are accumulated to generate the total displacement at the nth piezo member. Preferably, at least one of the n−1 levers are rotatably disposed in the body such that the displacement from one of the n piezo members acting on the first end of the at least one of the n−1 levers is amplified at the second end of the at least one of the n−1 levers.Type: GrantFiled: September 23, 2002Date of Patent: August 10, 2004Assignee: Lockheed Martin CorporationInventor: Renato Guida
