20120085973 | METHOD FOR PRODUCING PROCESS GAS FOR THE CLAUS PROCESS - With a method configured to generate process gas that contains hydrogen sulfide and sulfur dioxide for the Claus process, hydrogen-sulfide containing feed gas is burnt with pure oxygen by means of several burners opening out into a combustion chamber wherein the pure oxygen is fed into the combustion chamber through a central tube each, the feed gas through a tube arranged coaxially around the central tube and inert gas as purge gas via an annular duct coaxially surrounding the feed gas tube. A favorable option of the method consists in the use of CO | 04-12-2012 |

20140275809 | Automated Diagnosis-Assisting Medical Devices Utilizing Pattern Localization Of Quasi-Periodic Signals - A method for localizing a pattern in a quasi-periodic signal includes estimating, using a controller, a rate or a frequency of a quasi-periodic signal, and defining a search window based on the estimated rate or frequency of the quasi-periodic signal. A starting position is defined in the received quasi-periodic signal, the starting position corresponding to a first maximum. A portion of the quasi-periodic signal in the search window is cross-correlated with a template signal pattern to be matched to produce a second maximum. The second maximum is defined by the controller as a new starting position. The new starting position is stored. | 09-18-2014 |
20140276132 | Automated Diagnosis-Assisting Medical Devices Utilizing Rate/Frequency Estimation - A method for processing a quasi-periodic signal includes receiving a representation of a quasi-periodic signal and removing a DC component from the received signal to produce a purely time-varying signal. The time-varying signal is filtered to produce a pre-processed signal and at least a portion of a representation of the pre-processed signal is auto-correlated with itself. A corresponding auto-correlation output is stored in a memory device for the at least portion of the representation of the pre-processed signal. A biphasic tapering function is applied to the auto-correlation output, the tapering function including a time constant parameter that is a function of the quasi-periodic signal and producing a first maximum. A representation, based on the first maximum, is stored in the memory device as an indication of a rate or a frequency of the quasi-periodic signal. | 09-18-2014 |

20140276133 | Automated Diagnosis-Assisting Medical Devices - A system includes an electronic stethoscope producing a quasi-periodic signal, a processor, and a memory device with stored instructions that, when executed by the processor, cause the system to receive a representation of the quasi-periodic signal, to remove a DC component from the received representation of the quasi-periodic signal to produce a purely time-varying signal, and to filter, the time-varying signal to produce a pre-processed signal. A portion of the pre-processed signal is auto-correlated with itself, and a corresponding auto-correlation output is stored. A biphasic tapering function is applied to the auto-correlation output and produces a first maximum, the function including a time constant parameter that is a function of the quasi-periodic signal. A representation is stored, based on the first maximum, as an indication of a rate or frequency of the quasi-periodic signal. | 09-18-2014 |
