20100069767 | SYSTEM AND METHOD FOR ANALYZING COMPLEX CURVATURE OF ECG CURVES - The present invention relates to a system and a method for analysis of ECG curvature, which system involves a mathematical analysis, which analysis comprises the following features where a number of different parameters are isolated and stored in computer means, where a first number of parameters are selected from at least one main group, where the selected parameters are combined in at least a first mathematical analysis. It is the object of the invention to improve mathematical analysis of ECG curvature particular for complex parts of the curvature such as notches or concavities. It is a further object of the invention to improve automatic quantification of symmetry, flatness and durations of ECG curvature. This can be achieved if the parameters are selected from groups of symmetry, flatness, duration and/or complexity, which parameters are used as input to an algorithm, where concavity intervals are evaluated on subsegments of the ECG segment and form the basis of up- and downwards concavity quantification, where the system based on an algorithm detects and quantifies concavity on ECG curvatures. Herby can be achieved that a complex curvature can be analysed and the complex curvature might indicate symptoms of diseases which are very difficult to read on ECG curvature by existing technology. This can lead to a more precise analysis where existing systems might by analysing the curvature give a first indication of a symptom. By then performing an analysis of the complex part of the curvature, further symptoms might be indicated. | 03-18-2010 |
20110184692 | SYSTEM AND A METHOD FOR SPATIAL ESTIMATION AND VISUALIZATION OF MULTI-LEAD ELECTROCARDIOGRAPHIC ST DEVIATIONS - A system and a method for spatially ordered estimation and visualization of multi-lead electrocardiographic ST deviations induced by myocardial ischemia, in which system a plurality of ECG signals are recorded from a ECG source, which signals are stored by a processor in a memory, which processor processes the signals to obtain ST deviation, which processor performs measurement of ST deviation from each lead where the processor performs a multi-dimensional estimation of an vector representing of the spatial direction and magnitude of the underlying cardiac injury-current giving rise to the measured ST deviations, which processor hereby estimates the spatial location and severity of myocardial ischemia. | 07-28-2011 |

20140070885 | POWER SUPPLY ARRANGEMENT FOR SINGLE ENDED CLASS D AMPLIFIER - A power supply arrangement for a single ended class D amplifier, including a first primary winding connected in series with a first switch between the positive supply rail and ground, a second primary winding in phase with said first primary winding and connected in series with a second switch between the negative supply rail and ground, and a controller adapted to apply a control signal to said first and second switches, said control signal (Q) having ON-pulses of a predefined pulse time separated by a dead time. In use, the primary winding connected to the supply rail with the highest numerical voltage will transform the rail voltage difference to the supply rail with the lowest numerical voltage through the opposite primary winding thus reducing any voltage unbalance between the windings. | 03-13-2014 |
20140077885 | TWO MODE POWER CONVERTER FOR AUDIO AMPLIFIERS - A power converter with positive and negative supply rail outputs for feeding a single ended class D amplifier, the converter comprising a transformer arrangement, a supply pump reduction arrangement connected between the secondary windings and the positive and negative supply rail outputs, and a boost drive mode switching arrangement. A controller is adapted to control the power converter in a negate drive mode and a boost drive mode, wherein the output voltage in the boost mode is increased by means of the transformer and the boost drive mode switching arrangement. The output voltages on the positive and negative rails can be generated at two different output voltage levels without changing the duty cycle or dead time of the control signals. | 03-20-2014 |
