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 |

| 20090177799 | LOW COMPLEXITY COMPRESSION OF SHORT MESSAGES - The present invention relates to a method for data communication, where the data compression and decompression is performed by use of a specific hash table, by which data compression a symbol for each data segment is generated, which symbols are transmitted to the receiver, in which receiver the symbols are decompressed by use of the specific hash table. It is the object of the invention to perform reliably and fast data transmission between communication devices by data compression. A further object of the inventions is to perform a secure communication between computerized devices. The object can be fulfilled by the preamble to claim one if modified in a way where the specific hash table is performed as a hash table array, which hash table array generates symbols comprising at least a hash count and a parity check, in which hash table array the parity check comprises generating of a data string, which data string is compared with a parity stored in the hash table, where if both parities are the same, the data model returns the count in the hash table element for transmission, where a zero count is returned indicating that the data string is not valid in the hash table an no transmission is performed. Hereby it can be achieved that the count in the hash table is controlled in that the count is not accepted until the parity check is accepted. After the symbol has been transmitted to a receiver it is very important that the symbol is correctly received. Therefore the parity check is performed once again after the symbol has been received to ensure that after the symbol has been received. | 07-09-2009 |

| 20090052703 | System and Method Tracking the Position of a Listener and Transmitting Binaural Audio Data to the Listener - A binaural technology method includes: determining positions related to position of both ears of a listener, receiving a wireless RF signal including binaural audio data is received, and presenting the binaural audio data to the listener By determining ear positions of a listener e.g. in 3D, information of the listener's position e.g. in a virtual environment is known, and further by wireless transmitting binaural audio signals to the listener, it becomes possible to transmit 3D audio data matching the listener's position and movements accordingly. Further, since the position of both ears is known, it is possible to individually match the binaural audio data to the listener, since it is possible to derive from the ear positions a distance between the listener's ears, and hereby a valuable parameter is known that can be used to generate binaural signals that individually fits the listener. Thus, the listener can be provided with a better 3D audio experience. Especially, the determined positions may correspond to ear canal reference points for the binaural audio data. The positions in the ears may be derived based on RF signals, e.g. by using earphones, e.g. in-the-ear type earphones, that are also used to wirelessly receive and reproduce the binaural audio data to the listener. The ear phones may be arranged to wirelessly transmit the determined position data to a remote processor that generates the binaural audio data accordingly.
