Publication number: 20090041380Abstract: In order to prevent interception of the information through the leakage electromagnetic waves when transmitting the information using an image display unit, an image converter generates plural converted images, stores the generated converted images in an image storage, an image output unit reads out the converted images from the image storage and transmits the converted images to a screen control unit successively. The screen control unit displays a reception image on an image display unit. The image output unit outputs the converted image group at a high speed, thereby performing a switching display on the image display unit, and to show an image visually equivalent to the input image.Type: ApplicationFiled: July 10, 2008Publication date: February 12, 2009Inventors: Takashi Watanabe, Hiroshi Sako, Hiroto Nagayoshi, Toshiro Uemura

Patent number: 7231601Abstract: A digital pen-based application form filling system with a modification prevention function, which eliminates a possibility that digital information initially written in digital paper using a digital pen may be modified deliberately or accidentally. The system prints a new fine pattern over areas in already written digital paper whose contents one wishes to protect against being modified. This printing adds a fine pattern to an original dot pattern already present on the digital paper to make it theoretically impossible to enter information into these areas using the digital pen.Type: GrantFiled: February 4, 2004Date of Patent: June 12, 2007Assignee: Hitachi, Ltd.Inventors: Hiroshi Sako, Naohiro Furukawa, Hisashi Ikeda, Yosuke Kato

Patent number: 7199714Abstract: In goods genuineness/counterfeit discrimination using IC tags, contradictory problems of the reliability and lifetime of the IC tags and the accuracy of goods genuineness/counterfeit discrimination are solved and circulation of goods mounted with defective IC tags is prevented. A ratio of a number of IC tags having sent information indicative of the fact that the IC tags are mounted on the same object member to a number of IC tags from which the information is to be sent originally is determined and the genuineness/counterfeit discrimination is performed with the ratio. With regard to adopting a combination of genuineness/counterfeit discrimination, information necessary for detection is added to goods and information of the inspection area is stored in the IC tags. When the number of defective IC tags is large, goods mounted with the IC tags is collected.Type: GrantFiled: January 11, 2005Date of Patent: April 3, 2007Assignee: Hitachi, Ltd.Inventors: Hiroshi Sako, Tatsuhiko Kagehiro, Hiroto Nagayoshi, Satomi Baba

Patent number: 7100110Abstract: When a filling person fills in a document using an electronic pen, a system refers to a document information file forming a history information file and an electronic pen information file. A judging part of the system judges the presence or absence of an entry authority over the document on the basis of the pen ID of the electronic pen and the electronic pen information file. The judging part judges an entry sequence to the document on the basis of the pen ID, a document ID applied to the document, and the document information file. A judged result is transmitted from a creating part via a communication controller to the electronic pen.Type: GrantFiled: May 22, 2003Date of Patent: August 29, 2006Assignee: Hitachi, Ltd.Inventors: Yoko Shiraishi, Naoko Tazawa, Hisashi Ikeda, Hiroshi Sako

Patent number: 6981637Abstract: An automatic teller machine capable of verifying the authenticity of bank notes while maintaining high-speed execution of transactions. The machine comprises a bill validator outputs a result of verification of whether a received note could be classified or not, and a cash box for notes unclassified by verification results, and a cash box for notes other than unclassified notes. After transaction hours, re-verification is carried out, in which notes are retrieved one sheet at a time from the unclassified note box and sensed again by a sensor, and the bill validator receives a signal from the sensor and re-verifies the note by using an algorithm with higher accuracy than in verification at the time of a receiving transaction.Type: GrantFiled: February 21, 2003Date of Patent: January 3, 2006Assignee: Hitachi, Ltd.Inventors: Hiroto Nagayoshi, Noriaki Fujimura, Hiroshi Sako, Tatsuhiko Kagehiro

Publication number: 20050093832Abstract: A mail system for executing a mail service has a user management part for managing the information that the user previously registered, and a unit for utilizing the registered information as the destination of mails, so that the addresses of recipients can be efficiently managed. The sender acquires an address card that has printed with a pattern linking with the information of recipients. This address card is used when the sender writes a mail, and thus it serves to reduce the load on the sending operation. If a pattern linking with usage history information is printed on the mail, it also reduces the burden on the reply operation in which the recipient sends a reply back to the sender. The use of this usage history information for grasping the usage serves to efficiently adjust and calculate the cost for the service.Type: ApplicationFiled: January 29, 2004Publication date: May 5, 2005Inventors: Naohiro Furukawa, Hisashi Ikeda, Hiroshi Sako, Yosuke Kato

Publication number: 20040260650Abstract: An object of the present invention is to trace a user who has deposited bills as counterfeit bank notes into an ATM. The ATM having a bill deposit function judges a denomination and genuineness of bills deposited by the user by a validator, extracts bill information and stores in a search DB its bill information to be matched with an account number of the user (first data). It stores, in a trace DB, bill information of bills judged as counterfeit bank notes by the validator (second data). The search DB is searched with the second data as a key to extract similar bill data for specifying, from a result, the user who has used the bills as counterfeit bank notes.Type: ApplicationFiled: June 10, 2004Publication date: December 23, 2004Inventors: Yuji Nagaya, Toshiro Uemura, Tatsuhiko Kagehiro, Hiroshi Sako

Publication number: 20020065847Abstract: When a form processing terminal fails to identify a form, image information of the identification-failed form is transmitted to a work center. A manager of form identification dictionary of the work center analyzes the cause(s) of the identification failure, and updates the form identification dictionary while allowing the form processing system to operate. Update information is transmitted to the form processing terminal. The form processing terminal can also transmit to the work center information, which characterizes the form type, together with the image of the identification-failed form. The use of the updated information of the form by the form processing terminal is recorded in a user action log for fee charging purpose.Type: ApplicationFiled: March 15, 2001Publication date: May 30, 2002Applicant: Hitachi, Ltd.Inventors: Naohiro Furukawa, Hiroshi Sako, Hiromichi Fujisawa

Patent number: 6246794Abstract: A character reading method has enhanced character segmentation accuracy and character string recognition accuracy for reading correctly hand-written addresses on postal matters. The method extracts provisional character patterns from image information of the address character string (step 206), creates a table 219 of tentative character patterns and implements the character classification for the tentative character patterns (step 207), extracts, specifically for characters of the street number portion of the address character string, periphery information (vertical and horizontal lengths, vertical/horizontal length ratio, pattern spacings, etc.) of tentative character patterns (step 212), and segments the character string into characters accurately based on the information (step 215).Type: GrantFiled: December 11, 1996Date of Patent: June 12, 2001Assignee: Hitachi, Ltd.Inventors: Tatsuhiko Kagehiro, Masashi Koga, Hiroshi Sako, Hiromichi Fujisawa, Hisao Ogata, Yoshihiro Shima, Shigeru Watanabe, Masato Teramoto
