Abstract: A method of indicating extant battery life has the steps of initially determining a first extant battery life value having a first confidence level and generating a perceivable indication of the first battery life value. The method also has the step of determining a second extant battery life value having a second confidence level and generating a perceivable indication of the second battery life value after generating the perceivable indication of the first battery life value. The second confidence level is higher than the first confidence level and the determination of the first extant battery life value is completed before the determination of the second extant battery life value is completed.

Abstract: A radiophone, arranged to assume a plurality of states, that includes a user interface provided with a display, a keypad, and control means. The keypad is arranged to enter the plurality of states, which changes the plurality of states.

The control means is arranged to control the display of an action, from said group of actions, as a default function, and to detect a state change event, which will change the state of the radiophone and redefine the functionality of the two soft keys in response to the preceding state and the nature of the detected state change event.

Abstract: This invention presents a voicing determination algorithm for classification of a speech signal segment as voiced or unvoiced. The algorithm is based on a normalized autocorrelation where the length of the window is proportional to the pitch period. The speech segment to be classified is further divided into a number of sub-segments, and the normalized autocorrelation is calculated for each sub-segment if a certain number of the normalized autocorrelation values is above a predetermined threshold, the speech segment is classified as voiced. To improve the performance of the voicing determination algorithm in unvoiced to voiced transients, the normalized autocorrelations of the last sub-segments are emphasized. The performance of the voicing decision algorithm can be enhanced by utilizing also the possible lookahead information.

Abstract: This invention relates to compression of prediction error in motion compensated video coding schemes. Prediction frame and motion vectors are used to extract useful information about the properties of the prediction error signal, e.g. its location, directionality, etc. This information does not need to be transmitted because the decoder of the proposed system includes means to extract this information. Information extracted by the encoder and decoder is used to adapt prediction error coding scheme which gives substantial bitrate reductions.
