    Abstract: A method and apparatus for calibrating or adjusting an accelerometer, wherein the accelerometer is held stationary to obtain the signal outputs from the accelerometer, representing component vectors making up the composite vector of 1 g. Thus, gain or sensitivity, and the zero-g signal offset along for each axis of the accelerometer is determined and adjustable.

    Abstract: A person's exercise monitored by using an accelerometer to detect and count the steps of the person. Furthermore, acceleration profiling distinguishes walking from running and total distance covered in the exercise is estimated using different stride lengths for walking and running. The person's pace may be maintained using a music playback unit capable of adjusting the rate of the playback so as to influence the person by the music tempo.

    Abstract translation: 通过使用加速度计来监测人的运动，以检测和计数人的步骤。 此外，加速度分析将步行与跑步区分开，运动中覆盖的总距离估计使用不同的步幅和行驶长度。 可以使用能够调节播放速率的音乐播放单元来维持该人的步速，以便通过音乐节奏来影响该人。

    Abstract: A musical jukebox is disclosed which provides for: fast archiving of songs; a flexible user interface; easy and convenient entry of, access to and/or display of data relating to songs archived by the jukebox; easy and convenient search and locate capabilities for locating, reviewing, retrieving and/or playing songs stored in the jukebox; and low cost relative to the functionality, features, conveniences and user-friendliness provided by the jukebox. Fast of flush archiving of songs (as well as other data and signals) is accomplished by first saving sets of data without compression, which allows the data to be entered quickly, and then, compressing later at an appropriate time. A unique MP3 bit allocation encoding scheme is used to compress data. A unique memory allocation supports fast data archiving. The user interface employs two-way communication between a remote control and the jukebox. A searchable song database is structured to enable very fast searching by music category, and also by title and artist. The jukebox is provided with an on-board song track database to automatically identify new songs input to the jukebox.

    Abstract: A personal audio player has a housing, an audio output device in the housing and an audio player in the housing and coupled with the output device for storing and playing audio files. Multiple display panels are located on the housing. Each display panel is controlled to have a unique presentation format for presenting different information to a user. A user interface on the housing has different illumination colors respectively corresponding to different operation modes of the audio player. A lyrics processor outputs lyric text to one of the display panels in synchronisation with playing of a corresponding audio file.
