  • Publication number: 20090326935
    Abstract: A method for compressing digital sound data in which method a sound signal is divided for encoding into temporal segments and the sound samples of a segment, which are originally presented by N0 number of bits, are requantized by one or more number of bits which are smaller than N0, is characterized in that an upper limit is set for the quantization error, and one of the greatest absolute sound samples of the segment is selected as a fixed point (xp) on the basis of which said smaller number of bits and the value of the quantization step are defined and such an amount of the sound samples of the segment are quantized by means of them that the upper limit of the quantization error is not exceeded, whereby the samples quantized in this way form a group of values associated to the fixed point (xp) concerned and quantized by said smaller number of bits and the value of the quantization step.

  • Publication number: 20090010554
    Abstract: In the method for compressing image data, a main block and it's sub-blocks are selected for processing and all sub-block groups and, finally, the main block to be compressed are processed in a fixed order starting from the lowest level blocks, i.e. blocks of level 1, whereby at the same time the status function is formed which is a series of numerical or status values depending in a certain way on the content of all sub-blocks of the main block. The original information of the blocks indicated by the status function is compressed into a small amount of values arranged in a certain way, and when decoding the image data, the original information of said blocks may be recovered at least approximately. In the encoding of each block of level 1, a threshold value and a quantization step may be defined and adapted in relation to each other or independently so that the relationship between the size and quality of the compressed image is optimal.

  • Publication number: 20070294640
    Abstract: The invention relates to a user interface of a player of a mobile device (10). The user interface comprises graphical icons (16) representing the functions of the player, of which icons only the ones that can be performed in the current mode of operation of the player are shown on the display (11) of the device. Each of the graphical icons shown on the display is associated with one of the keys (12, 13, 14) of the device. In addition, the user interface comprises, in at least two languages, operating instructions, which are saved in the memory of the device as a text file. The invention also relates to a method and computer program product for implementing the user interface of a player.

  • Patent number: 4999584
    Abstract: The invention relates to a signal-shaping network comprising a differential amplifier (G) having an output and an inverting (A) and a non-inverting (B) input between which a signal source (S) is connected. When a differential amplifier is used particularly for the measuring of very weak biosignals, interference signals may easily make the measuring completely impossible. In the signal-shaping network according to the invention, interferences have been eliminated in such a way that an integrating feedback circuit (1a; 1b) is connected between the output and one input of the differential amplifier (G) and/or a derivative feedback circuit (2a) is connected between the output and the other input of the differential amplifier. In this way an adaptive differential amplifier is achieved which attenuates slow interference signals and/or rapid interference signals.
