Patent number: 8200973Abstract: A sink device including a first data processing unit and a second data processing unit authenticates the processing units, when turned on, to generate first authentication keys having the same data. When a data request is issued from the sink device to the source device, device authentication is made between the source device and the first data processing unit to generate second authentication keys having the same data. The source device encrypts an exchange key using the second authentication key, and sends the encrypted exchange key to the first data processing unit. The first data processing unit decrypts the encrypted exchange key using the second authentication key, encrypts the decrypted exchange key using the first authentication key, and sends the encrypted exchange key to the second data processing unit. The second data processing unit decrypts the encrypted exchange key using the first authentication key to obtain an exchange key.Type: GrantFiled: November 13, 2008Date of Patent: June 12, 2012Assignee: Alpine Electronics Inc.Inventors: Akihiro Kubota, Hideyuki Hatakeyama

Patent number: 6674415Abstract: Three lines' worth of an image are displayed on a columnar display unit 11 comprising a plurality (for example, three) of one-dimensional display devices; this image light beam is made incident on perpendicular deflection means 14, and using the perpendicular deflection means 14, this image light beam is deflected and scanned at high speed in directions perpendicular to the longitudinal direction of the columnar display unit 11 to obtain a two-dimensional image. A plurality of one-dimensional display devices is used, so that compared with conventional devices in which only a single one-dimensional display device is used, even if the rewrite speed (scanning speed) per one-dimensional display device is slow, good image quality free of flicker can be obtained. By further extending this in a configuration using a plurality of columnar display units, a single image can be divided into a plurality of images and displayed in a row on a screen.Type: GrantFiled: March 15, 2001Date of Patent: January 6, 2004Assignee: Olympus Optical Co., Ltd.Inventors: Tomoyuki Nakamura, Susumu Kobayashi, Akihiro Kubota, Hiroyoshi Kobayashi
