| 20100058242 | MENU DISPLAY DEVICE AND MENU DISPLAY METHOD - A menu display device includes a display unit that displays a plurality of menu options side by side on a display screen, a storage unit that stores the menu options and operational commands for specifying operations corresponding to the menu options, and a control unit that displays the menu options and displays the operational commands adjacent to the menu options, the operational commands controlling display of the menu options. The control unit moves a mark that indicates a selectable state between the menu options or the operational commands in response to an amount of operation of an operation unit, and when the mark moves to the operational commands, the control unit displays new menu options on the display screen in response to the operational commands. | 03-04-2010 |
| 20090320054 | DISK DEVICE - To provide a “disk device” that does not waste a power during waiting for disk insertion and thus can save power consumption. The disk device includes: a casing equipped with an insertion port to which a disk is inserted; a conveying mechanism for conveying a disk, which is provided inside the insertion port; a switching type detecting switch that is switched to a detection state in accordance with a movement force of a disk inserted from the insertion port in an insertion direction; and an optical detecting member that is switched to a detection state when a disk inserted from the insertion port blocks an optical path, wherein when the detecting switch is switched to a detection state, power supply to the optical detecting member is started. | 12-24-2009 |
| 20090313647 | DISC APPARATUS - A shutter member is provided so as to be capable of moving in association with a roller bracket. The shutter member rotates by a predetermined range in association with the rotation of the roller bracket, and then a projection of the shutter member is pressed in a Y1 direction by a shutter pressing portion provided on the right side slider. Accordingly, the shutter member is rotated clockwise, and an opening and closing panel portion of the shutter member closes an insertion port from the inside thereof. Therefore, the insertion port is closed reliably by the shutter member, so that insertion of another disc from the insertion port into the interior of the apparatus while the disc is rotating is prevented. | 12-17-2009 |
| 20090299627 | RADAR MONITORING DEVICE - When a vehicle moves into a radar prohibited area preset for the neighborhood of a facility that suffers adverse effects from radar waves, emission of radar waves is stopped, and a voice guidance such as “Radar monitoring is stopped” is sent to a speaker via a voice output unit. Moreover, during a period in which a vehicle is located in a radar prohibited area, an icon that indicates that a radar is being stopped, a mark that indicates an institution for which the radar prohibited area is set, and the scope of the radar prohibited area are displayed on a map image. | 12-03-2009 |
| 20090279706 | SURROUND GENERATION APPARATUS - A surround system includes a decoder that decodes an encoded audio data stream, a decorrelation unit that receives and decorrelates stereo signals decoded by the decoder so as to generate surround signals having a low-correlation component, an addition unit that adds high-correlation-component signals extracted from the stereo signals to the surround signals generated by the decorrelation unit, and a controller that controls addition of the high-correlation-component signals performed by the addition unit on the basis of the bit rate of the audio data stream. | 11-12-2009 |
| 20090240508 | SAMPLING RATE CONVERSION APPARATUS AND METHOD THEREOF - A sampling rate conversion apparatus and a method thereof are provided which increase the sampling rate of a discrete audio signal sampled at a predetermined sampling rate by using a fractal interpolation function (FIF). An audio signal portion formed by a predetermined number of sampling data items is divided into a plurality of interpolation intervals. On the audio signal portion, mapping points are determined. The number of the mapping points is in accordance with the degree of increase in the sampling rate. For the respective interpolation intervals, mapping parameters for performing mapping using the FIF on the mapping points are calculated. In all of the interpolation intervals, the mapping using the FIF is performed on the mapping points with the use of the mapping parameters according to the respective interpolation intervals. Thereby, new sampling data items are generated. | 09-24-2009 |
