Portable telephone apparatus having a plurality of selectable functions activated by the use of dedicated and/or soft keys

Abstract: A telephone apparatus having a plurality of dedicated keys, a plurality of changeable keys each having at least one respective dedicated function associated therewith, and a display for displaying a plurality of lines of data. The telephone apparatus is adapted to perform a plurality of main functions including so-called menu, message, pad and book functions. Each of such main functions may be directly accessed by depressing only one of the keys. Further, the telephone apparatus enables messages, including voicemail and text data messages, to be received and stored therein. Messages or responses to received messages may be produced and transmitted from the telephone apparatus.

Recording medium, recording device, reproduction device, recording method, and reproduction method

Abstract: A recording medium capable of improving usefulness of a write once type recording medium. In the write once type recording medium, there are provided a normal recording/reproduction area, an alternate area, a first alternate management information area (DMA), and a second alternate management information area (TDMA), and furthermore, write presence/absence marker information (space pit map) is recorded. The second alternate management information area is an area for realizing rewrite of alternate management information by additionally writing alternate management information associated with alternate processing. Furthermore, according to the write presence/absence marker information, it is possible to judge whether the each data unit (cluster) on the recording medium has been written in or not. Thus, it is possible to appropriately realize defect management and data rewrite in the write once type medium.

Mobile apparatus having tactile feedback function

Abstract: A haptic display includes at least one haptic device that can give tactile feedback instead of visible feedback. Each of the haptic devices converts a signal from a signal producing unit into force or tactile pattern. The haptic device does not require a large mass, so that it can be provided on almost any portion or part within the body of a mobile apparatus. For example, the haptic device can be embedded under a touch panel display that constitutes both input and output device. By providing the haptic devices under respective menu/function button areas displayed on the touch panel display, it is possible to stimulate the specific button in response to the user-input-operation, thereby directly providing the tactile feedback to the user's finger touching the corresponding button.

Electronic apparatus, display controlling method for electronic apparatus and graphical user interface

Abstract: A graphical user interface is disclosed which achieves an easy search for a desired item upon scrolling. A plurality of representation images individually representing different selection object items are displayed in an array along one direction of a display screen. A noticed representation image selected from among the representation images is displayed emphatically at a fixed position on the display screen, and explanation information of the noticed representation image is displayed in the proximity of the noticed representation image. If a scrolling information for the array of representation images is issued, then scrolling is executed such that explanation information also of the representation images other than the noticed representation image is displayed. Further, a bar display including a mark representing the position and the group of the noticed representation image in the array of representation images is displayed together.

On the use of zero-crossing rate for an application of classification of percussive sounds

Abstract: We address the issue of automatically extracting rhythm descriptors from audio signals, to be eventually used in content-based musical applications such as in the context of MPEG7. Our aim is to approach the comprehension of auditory scenes in raw polyphonic audio signals without preliminary source separation. As a first step towards the automatic extraction of rhythmic structures out of signals taken from the popular music repertoire, we propose an approach for automatically extracting time indexes of occurrences of different percussive timbres in an audio signal. Within this framework, we found that a particular issue lies in the classification of percussive sounds. In this paper, we report on the method currently used to deal with this problem.
