Patent number: 10992274Abstract: This application relates to methods and apparatus for audio signal processing, for example by a codec. An audio signal processing module has at least one input for receiving first and second input signals and an output path for outputting an output audio signal. The first and second input signals may be supplied by a first audio component and may correspond to the same source audio data. A controller is configured to compare the first and second input signals and to select one of the first or second input signals as the basis for a signal to be supplied to said output path based on the comparison. The controller may determine a measure of similarity in content between the first and second input signals.Type: GrantFiled: October 31, 2019Date of Patent: April 27, 2021Assignee: Cirrus Logic, Inc.Inventors: Morgan Timothy Prior, Robert Rand

Patent number: 10511277Abstract: This application relates to methods and apparatus for audio signal processing, for example by a codec. An audio signal processing module (301) has at least one input (303, 304) for receiving first and second input signals (Din1, Din2) and an output path for outputting an output audio signal (Vout). The first and second input signals may be supplied by a first audio component (100) and may correspond to the same source audio data. A controller (305) is configured to compare the first and second input signals and to select one of the first or second input signals as the basis for a signal to be supplied to said output path based on the comparison. The controller may determine a measure of similarity (Sim) in content between the first and second input signals.Type: GrantFiled: June 30, 2016Date of Patent: December 17, 2019Assignee: Cirrus Logic, Inc.Inventors: Morgan Timothy Prior, Robert Rand

Publication number: 20160331759Abstract: A medicinal composition is administered orally twice a day to a patient to ameliorate the symptoms related to Parkinson's disease. The medicinal composition includes mixing a quantity of ibogaine, a quantity of vitamin supplements and a quantity of manufacturing additives into a heterogeneous medicinal mixture. The quantity of ibogaine, formulated as ibogaine HCl, other non-toxic salts of ibogaine (an alkaloid of the family apocynaceae), or noribogaine, its active metabolite, is an active ingredient to regulate endogenous glial cell line-derived neurotrophic factor (GDNF). The quantity of vitamin supplements promotes the general health and neurological functions. The quantity of manufacturing additives bonds the quantity of ibogaine and the quantity of vitamin supplements together, as well as, provides anti-adherent properties to prevent the medicinal mixture from adhering to manufacturing equipment.Type: ApplicationFiled: July 29, 2016Publication date: November 17, 2016Inventor: Robert Rand

Patent number: 8811563Abstract: A system and method for assessing failure of fuel rods are disclosed. The method may include monitoring fuel rod operational conditions, comparing the fuel rod parameters to parameters limits, calculating the fuel rod performance parameters to determine the likelihood of failure of individual fuel rods, and updating plant operating parameters based on the calculated fuel rod parameters. The system may input the calculated fuel rod parameters into a fuel failure model to assess the probability of failure, and predict the probability of failure of individual fuel rods based on fuel rod parameters in the fuel failure model.Type: GrantFiled: December 30, 2004Date of Patent: August 19, 2014Assignee: General Electric CompanyInventors: Harold Yeager, Russell Stachowski, Charles McNeely, Gerald Potts, Anthony Reese, Robert Rand, Robert Schneider, Angelo Chopelas

Publication number: 20070177710Abstract: In a method of determining a cell friction metric for a control cell of a nuclear reactor, a channel face fast fluence and/or a channel face controlled operation parameter is determined for all channels. A total bow value is calculated for each channel based on the channel face fast fluence and/or channel face control parameters. For each channel, a channel wall pressure drop parameter is determined, and a total bulge value is calculated for each channel using the channel face fast fluence and channel wall pressure drop parameters. Total deformation at specified channel axial elevations for the cell is determined based on the total bow and bulge values. A control blade axial friction force value is calculated at each axial elevation based on the total deformation, along with channel stiffness and channel-control blade friction coefficient values. A maximum friction value is selected as the cell friction metric for the cell.Type: ApplicationFiled: January 27, 2006Publication date: August 2, 2007Inventors: Atul Karve, Gerald Potts, Mark Dubecky, Robert Rand, Gerald Latter, Brian Moore

Publication number: 20070031042Abstract: A wavelet-based band difference-sum ratio method reduces the computation cost of classification and feature extraction (identification) tasks. A Generalized Difference Feature Index (GDFI), computed using wavelets such as Daubechies wavelets, is employed in a method to automatically generate a large sequence of generalized band ratio images. In select embodiments of the present invention, judicious data mining of the large set of GDFI bands produces a small subset of GDFI bands suitable to identify specific Terrain Category/Classification (TERCAT) features. Other wavelets, such as Vaidyanathan, Coiflet, Beylkin, and Symmlet and the like may be employed in select embodiments. The classification and feature extraction (identification) performance of the band ratio method of the present invention is comparable to that obtained with the same or similar data sets using much more sophisticated methods such as discriminants, neural net classification, endmember Gibbs-based partitioning, and genetic algorithms.Type: ApplicationFiled: July 12, 2006Publication date: February 8, 2007Inventors: Edmundo Simental, Edward Bosch, Robert Rand

Publication number: 20050047663Abstract: A method that facilitates identification of features in a scene enables enhanced detail to be displayed. One embodiment incorporates a multi-grid Gibbs-based algorithm to partition sets of endmembers of an image into smaller sets upon which spatial consistency is imposed. At each site within an imaged scene, not necessarily a site entirely within one of the small sets, the parameters of a linear mixture model are estimated based on the small set of endmembers in the partition associated with that site. An, enhanced spectral mixing process (SMP) is then computed. One embodiment employs a simulated annealing method of partitioning hyperspectral imagery, initialized by a supervised classification method to provide spatially smooth class labeling for terrain mapping applications. One estimate of the model is a Gibbs distribution defined over a symmetric spatial neighborhood system that is based on an energy function characterizing spectral disparities in both Euclidean distance and spectral angle.Type: ApplicationFiled: June 26, 2003Publication date: March 3, 2005Inventors: Daniel Keenan, Robert Rand
