Patent number: 9709594Abstract: A laser Doppler velocimeter uses self-mixing amplification of backreflections from scatterers below the surface of a flow. A time domain signal is divided into segments that are roughly equal to a transit time of particles through a focus of a laser beam. The segments are connected to a frequency domain through the use of an FFT algorithm to produce frequency domain data segments. Signal-to-noise ratio is enhanced through signal processing techniques using the segments to produce a final enhanced signal spectrum.Type: GrantFiled: April 10, 2014Date of Patent: July 18, 2017Assignee: Teledyne Technologies IncorporatedInventors: William R. Christian, Ray C. Delcher, Tong Chen, Mohsen Khoshnevisan, Phillip B. Liescheski, Michael A. Metcalf

Patent number: 8046588Abstract: System(s) and method(s) that facilitate utilizing biometric sensors (e.g., fingerprint, hand scan, voice recognition . . . ) in manufacturing systems in order to maintain accurate safety audit trails. A safety audit system, utilizing a biometric sensing device, facilitates determining if a user is allowed to access and change the configuration of the manufacturing system. Once a user is allowed to change the configuration (e.g., programmable electronics, tooling changes, software updates, etc.) the changes are automatically recorded in a safety audit database. Automatic storage of configuration changes mitigates manual recording of changes thereby enhancing the safety audit data often necessary to meet safety standards for manufacturing systems.Type: GrantFiled: February 23, 2006Date of Patent: October 25, 2011Assignee: Rockwell Automation Technologies, Inc.Inventors: Anthony G. Gibart, James E. Dogul, Richard Galera, George E. Rollins, Derek W. Jones, George K. Schuster, Suresh R. Nair, Ray C. Delcher

Patent number: 7356209Abstract: An optical power converting apparatus is provided that may be used with remote sensors. A plurality of remote sensors may be coupled to a backbone optical fiber with each sensor having an optical power converter that receives an optical signal from a head end of that fiber. The optical power converters may store electrical energy derived from that optical signal and use that energy to power the remote sensors. The head end's optical signal may also include a clock signal, and each remote sensor may be set to sense a measurable parameter after a given number of clock cycles have been counted. In a further example, each of the optical sensors may be synchronized before counting these clock signals via a synchronization signal from the optical power converter. The remote sensors may individually and separately uplink their sensed data to the head end on the optical fiber. The apparatus may be implemented in a vehicle health management system, for example.Type: GrantFiled: July 19, 2007Date of Patent: April 8, 2008Assignee: Boeing CompanyInventors: Ray C.

Patent number: 4772789Abstract: A method for detecting, locating and measuring leaks in a test object is described using a differential absorption technique. In a preferred embodiment the test object is first pressurized with a light absorbing fluid. The test object is then illuminated with a light source at a wavelength which is capable of being absorbed by the absorbing fluid. An image of the test object and any fluid in the vicinity of the test object is created by means of a video camera directed toward the test object and that image is electronically stored. A second image is then created in such a manner that any absorbing fluid in the vicinity of the test object does not appear in that second image. The second image is also electronically stored. The electronically stored information regarding the first and second images are then compared and analyzed for detecting, locating and measuring any leaking fluid from the test object.Type: GrantFiled: December 28, 1987Date of Patent: September 20, 1988Assignee: Rockwell International CorporationInventors: Jonathan M.
