Latest Patents

One of Sakamoto's latest patents is a digital signal reproducing apparatus. This innovative device is capable of reproducing video and audio information from a compact disk without losing the beginning of the content, even when the information is recorded simultaneously from the first block of any specified selection. The apparatus includes a reproduction position detector that outputs the current reproduction position based on subcode information. Additionally, an offset reproducer offsets the disk track being reproduced to a position before the current reproduction position after accessing the specified reproduction position, allowing for seamless playback. The device also features first and second shift controllers that output position information by adjusting the access position information. Furthermore, a digital muting canceler and a video muting canceler ensure that audio and video muting are canceled at the appropriate reproduction positions.

Another significant patent is a liquid crystal display (LCD) circuit. This circuit comprises a duty changing device that alters the driving duty cycle of the LCD based on a power supply switching command signal. It also includes a bias changing device that adjusts the display bias voltage to maintain display quality, even when the power supply is switched. This innovation helps suppress changes in display contrast, ensuring a consistent viewing experience.
