Publication number: 20230107060Abstract: A vehicle display control device includes a hardware processor functioning as a regulation recognition unit, a regulation validity determination unit, and a display controller. The regulation recognition unit serves to recognize a traffic regulation mark indicating a traffic regulation provided on a traveling route of a host vehicle. The regulation validity determination unit serves to determine whether or not regulation content information is valid. The regulation content information is content of the regulation indicated by the traffic regulation mark recognized by the regulation recognition unit. The display controller serves to control a display device mounted on the host vehicle to display the regulation content information in a display region. The display controller changes a display mode of the regulation content information in response to determining by the regulation validity determination unit that the regulation content information is not valid.Type: ApplicationFiled: August 29, 2022Publication date: April 6, 2023Applicant: Panasonic Intellectual Property Management Co., Ltd.Inventors: Taiki TAKAAZE, Asuka EGASHIRA, Seigo TAKADA, Hirokazu TOKUDA, Hiroshi TAKEKAWA, Masato NOGUCHI, Kyouji TANAKA

Publication number: 20220135050Abstract: An eye-gaze input apparatus includes a hardware processor functioning as an eye-gaze determination unit, an input/output processing unit, and a careless-state determination unit. The eye-gaze determination unit determines a first input by an eye gaze of a user with respect to first images of input elements displayed in a display region set in front of a windshield and a driver seat of a vehicle. The careless-state determination unit determines whether the user is in a careless state. The input/output processing unit confirms the first input in a case where the eye-gaze determination unit determines that there is the first input on any of the one or more first images and the careless-state determination unit determines that the user is not in the careless state, and does not confirm the first input in a case where the careless-state determination unit determines that the user is in the careless state.Type: ApplicationFiled: October 27, 2021Publication date: May 5, 2022Applicant: Panasonic Intellectual Property Management Co., Ltd.Inventors: Asuka EGASHIRA, Seigo TAKADA, Taiki TAKAAZE, Kenya MATSUSHITA, Hiroshi TAKEKAWA

Patent number: 8572386Abstract: The present invention is designed to enable a secure device to authenticate a terminal application that operates on an information processing terminal and that accesses the secure device. An application issue request transmitter (301) of the information processing terminal (30) sends a request for issue of a terminal application to an application issuer (101). The application issuer (101) of an secure device (10) reads a terminal application (31) from an application storage (105) and embeds authentication information in the terminal application (31), associates an ID and the authentication information of the terminal application (31) and save them in an issue information storage (106), and sends the terminal application (31) to an application receiver (302) of the information processing terminal through an application transmitter (102). The application receiver (302) starts the terminal application (31).Type: GrantFiled: August 4, 2004Date of Patent: October 29, 2013Assignee: Panasonic CorporationInventors: Hiroshi Takekawa, Hisashi Takayama, Ken Naka

Publication number: 20100107034Abstract: The present invention intends to hold safely string information such as secret information, or the like, and also to lessen user's burden of storing the information in connection to the string information. In registering the secret information, a coding section 16 synthesizes input correct secret information SD and individual characteristic information under a predetermined rule, and produces a code word S16. A check symbol for error correction is produced in the course of the coding of the coding section 16, and this check symbol is stored in a storing section 20. In reproducing the secret information, an error correcting section 22 applies an error correcting process using the check symbol stored in the storing section 20 to a code word, which is produced by the coding section 16 based on the input secret information SD and the individual characteristic information, as the object. Accordingly, the correct secret information is reproduced.Type: ApplicationFiled: March 7, 2008Publication date: April 29, 2010Applicant: PANASONIC CORPORATIONInventors: Emi Tsurukiri, Hiroshi Takekawa, Hayashi Ito

Patent number: 7701670Abstract: A medium-opposed surface of a slider body is hemisected into first and second areas by the centerline extending in the longitudinal direction of the slider body. The second area is designed to generate a positive pressure larger than that generated at the first area when a load acting on the slider body in a direction toward a recording medium decreases. The head slider of the type is allowed to enjoy the imbalance of the lift on the slider body. This imbalance can be utilized to intentionally induce increases in the roll angle and the pitch angle of the slider body. The increase in the roll and pitch angles causes disappearance of the lift and the negative pressure generated at the medium-opposed surface. The head slider can reliably be distanced from the moving surface of the recording medium solely with the assistance of the airflow acting on the medium-opposed surface.Type: GrantFiled: February 19, 2008Date of Patent: April 20, 2010Assignee: Toshiba Storage Device CorporationInventors: Takeshi Ohwe, Atsushi Suzuki, Hiroshi Takekawa, Kazuhiro Watanabe

Publication number: 20090287939Abstract: A secure device can make contents of terminal application authentication information calculation a different complicated calculation process at each time while suppressing the processing load in the secure device and a card application code size to low values. When issuing of a terminal application (302) is requested from an application loader (301) to an application management unit (1011), an instruction content execution unit (1012) embeds authentication information used for calculation of an authentication key required for authentication with an application causing an information processing terminal (30) to perform a process, into the terminal application (302). A calculation complicating unit (1013) creates a calculation problem having a calculation result as an answer and embeds it as a part of the authentication information calculation into the terminal application (302).Type: ApplicationFiled: December 7, 2006Publication date: November 19, 2009Applicant: MATSUSHITA ELECTRIC INDUSTRIAL CO., LTD.Inventors: Hiroshi Takekawa, Hisashi Takayama

Patent number: 7600228Abstract: With respect to a secure device 10 for executing a data storing operation and a data calculating operation under secrecy condition, a first application program 15 and a second application program 11 are retained. The program 15 causes an information processing terminal 30 mounted thereon this secure device 10 to execute a process operation by utilizing a resource of this information processing terminal 30. The program 11 causes the secure device 10 to execute such a process operation under secrecy condition in conjunction with the process operation of this information processing terminal 30. When this secure device 10 is mounted on the information processing terminal 30, this secure device 10 loads the program 15 to the information processing terminal 30 so as to install this loaded first application program therein. Then, a terminal application program required to execute a service is automatically installed to the information processing terminal 30.Type: GrantFiled: July 14, 2004Date of Patent: October 6, 2009Assignee: Panasonic CorporationInventors: Hiroshi Takekawa, Hisashi Takayama, Hayashi Ito, Tsuyoshi Sakata, Hiroshi Nishikawa
