Publication number: 20220208189Abstract: The risk of mishearing by users in an environment where important information is transmitted is reduced. A voice segment detection unit detects a voice segment from an environmental sound. A user relevance determination unit determines whether voice in the voice segment is related to a user. For example, the user relevance determination unit extracts keywords related to actions from the voice in the voice segment, and determines whether the voice in the voice segment is related to the user on the basis of the relevance of the extracted keyword to the user's actions. A presentation control unit controls presentation of the voice related to the user. For example, the presentation control unit controls the presentation of the voice related to the user when the user is in a mishearing mode.Type: ApplicationFiled: March 30, 2020Publication date: June 30, 2022Inventor: YASUNARI HASHIMOTO

Patent number: 8014998Abstract: A storing unit stores therein a plurality of different display language data that is switchable according to a use environment of a user. A selecting unit selects a display language data from the storing unit in response to display language specification information supplied from a main unit at a time of starting the electronic device. A displaying unit displays an operation screen with selected display language data. When there is no display language specification information from the main unit, the selecting unit selects a predetermined display language data according to a difference between stored display language data and display language data set in a factory setting.Type: GrantFiled: March 15, 2007Date of Patent: September 6, 2011Assignee: Ricoh Company, LimitedInventor: Yasunari Hashimoto

Patent number: 5907319Abstract: In an image forming apparatus, picture display control means causes display means to selectively display a simple picture which allows a limited number of basic functions to be selected, or a standard picture which allows all the functions, inclusive of the functions available with the simple picture, to be selected. The simple picture and standard picture are switched over by software. The operation of the apparatus may be permitted only when a user code matching any one of user codes registered beforehand is input; either the simple picture or the standard picture may be set for each user code and displayed as the initial picture. The apparatus allows the operator to set up functions matching the contents of image formation and operator's skill without resorting to an openable cover for concealing a part of function setting keys.Type: GrantFiled: March 7, 1996Date of Patent: May 25, 1999Assignee: Ricoh Company, Ltd.Inventors: Yasunari Hashimoto, Yoshimine Horiuchi, Masao Moriya, Shunsuke Watanabe

Patent number: 5784663Abstract: A control system for collectively supervising a plurality of copiers or similar image forming apparatuses connected to a control device by communication lines with or without the intermediary of communication control units. To down-load data relating to image formation, the control device determines whether or not a copier of interest is in an inoperative state and, if it is in an inoperative state, automatically sends the data to the copier via a telephone line, an exchange, and a communication control unit. This data is written to storing means built in the copier. To up-load data relating to image formation, the control device causes each copier to automatically send the data stored in the storing means and stores the data in memory means. Up-loading is effected at an optimal time other than the time when the copier is performing an automatic adjustment, is in use, or is quite likely to be used.Type: GrantFiled: March 7, 1997Date of Patent: July 21, 1998Assignee: Ricoh Company, Ltd.Inventors: Masayuki Hayashi, Yoshihiro Mitekura, Koichi Kanaya, Masato Terao, Toshiya Tagawa, Nobuaki Tomidokoro, Masahiro Kitayama, Osamu Kizaki, Yasuo Kawada, Kazuyuki Nakahara, Tomofumi Harada, Yasunari Hashimoto
