Patent number: 9400560Abstract: Disclosed is an image display device capable of recognizing a hand of a user and predefining an operating region. Image recognition means recognizes the position of a hand of the user. Operating region setup means predefines the operating region, on an imaging region plane of imaging means and around a position on which the user's hand is projected, for the purpose of enabling the user to issue instructions to the image display device. When the position on which the user's hand is projected moves and comes close to the periphery of the operating region, the operating region setup means moves the operating region in the direction of the movement of the position on which the user's hand is projected. Further, the image recognition means recognizes a hand-waving motion of the user, whereas the operating region setup means sets the size of the operating region in accordance with the magnitude of the user's hand-waving motion.Type: GrantFiled: September 24, 2010Date of Patent: July 26, 2016Assignee: HITACHI MAXELL, LTD.Inventors: Takashi Matsubara, Masumi Moritani

Patent number: 7873767Abstract: A wireless IC memory, for improving the security thereof, for achieving protection of business information and privacy, comprises an RFID tag 100, wherein it is possible to setup “readout disenabling (ReadLock)” condition to the UII code bank for storing ID data of the RFID tag 100, with a predetermined protocol from an external communication apparatus, within the RFID tag 100. Setup of “readout disenabling (ReadLock)” condition is stored on a readout enabling/disenabling condition memory portion 105 within the RFID tag 100. In case where the “readout disenabling (ReadLock)” condition is set up in the UII code bank, a protocol process controller portion 103 of the RFID tag 100, not responding the UII code, normally, but answers a fake UII code or an error code, or gives no answer, to a request or command of readout of the UII data from the external communication apparatus.Type: GrantFiled: August 29, 2007Date of Patent: January 18, 2011Assignee: Hitachi, Ltd.Inventors: Masumi Moritani, Shinichiro Fukushima, Hiroyuki Higaki, Yuichi Kobayashi, Atsushi Honzawa

Patent number: 7737824Abstract: A hierarchical structure is established among a plurality of RFID tags, such that ID numbers can be read only from RFID tags which belong to a particular layer. RFID tag can control whether permission should be given to read its ID number therefrom to protect the ID number. Data held in the RFID tag can be read from the outside. RFID tag comprises a memory circuit having a function of holding data, and a logic circuit having a function of processing a control command received from outside. Memory circuit stores an own ID number for identifying the RFID tag itself, and a parent ID number for identifying a second RFID tag. When RFID tag receives an ID number read command which contains first data as a parameter from outside, the logic circuit outputs the own ID number to outside only when the first data matches the parent ID number.Type: GrantFiled: December 28, 2005Date of Patent: June 15, 2010Assignee: Hitachi, Ltd.Inventors: Makoto Aikawa, Yutaka Takami, Shinichiro Fukushima, Masumi Moritani, Hashimoto Kazunori

Publication number: 20080224833Abstract: An information management system comprises information processing unit 51 which reads out self ID number data and reference ID number data from each RFID tag, and additionally writes all the self ID number data and reference ID number data into an ID table. The data in each row of the ID table is the self ID number data and reference ID number data that are stored in each RFID tag. “0” is set to all rows of a link flag setting region, and it is checked whether a value in the M-th row of the reference ID number data is equal to a value in the N-th row of the self ID number data. If both are equal, then “1” is set to the N-th row in the link flag setting region. These processing operations are repeated for all rows of the ID table.Type: ApplicationFiled: February 15, 2008Publication date: September 18, 2008Inventors: Makoto Aikawa, Shinichiro Fukushima, Masumi Moritani, Hiroyuki Higaki, Yuichi Kobayashi, Atsushi Honzawa, Akira Kishida

Publication number: 20080094183Abstract: For making difficult to copy data of a RFID tag, while enabling to detect it when copying the data, easily, but without exerting ill influences upon the existing specification thereof, within the RFID tag 100 is provided a readout exclusive bank, other than banks provided in accordance with the existing specification. RFID identification information is stored into the readout exclusive bank of the RFID tag 100, when the RFID tag 100 is shipped out of a maker. A user who wishes to guarantee properness of UII data produces cryptograph calculation result data through encrypting the RFID identification information and the UII data, when writing the UII data into the RFID tag 100, and stores the cryptograph calculation result data into a USER bank within the RFID tag 100.Type: ApplicationFiled: July 31, 2007Publication date: April 24, 2008Inventors: Shinichiro Fukushima, Masumi Moritani, Hiroyuki Higaki, Yuichi Kobayashi, Atsushi Honzawa

Publication number: 20040027312Abstract: Hands-free operation is a prerequisite in wearable PCs; a problem in such PCs is that intuitive input or direct input such as pen input or touch panel input is impossible, so that a comfortable input operation cannot be performed. In order to solve this problem, the portable information device of the present invention comprises a portable main body part, and an HMD which is connected to this main body part, and which is mounted on the head. Furthermore, the abovementioned main body part comprises an input display part which displays to the outside image information consisting of a smaller amount of data than the image information displayed on the abovementioned HMD, and which inputs operating information from the outside on a displayed screen, an output part which outputs information to the abovementioned HMD, and a control part which controls the image information that is displayed on the abovementioned HMD on the basis of the operating information that is input in the abovementioned input display part.Type: ApplicationFiled: March 21, 2003Publication date: February 12, 2004Inventors: Norio Owada, Osamu Ebina, Akinori Maeda, Masumi Moritani, Ichiro Ote, Yoshinobu Ohinata, Akihiro Yoshida, Taichi Koriyama, Kimihiko Adachi
