Publication number: 20150379310Abstract: According to one embodiment, an electronic apparatus includes a first determination controller, a second determination controller and a security controller. The first determination controller determines, at intervals of a first time period, whether or not communication with a management server is executable. The second determination controller determines, when it is determined that the communication with the management server is not executable, whether or not a second time period elapses from a last one of times at each of which it is determined that the communication with the management server is executable. The security controller executes a process for inhibiting use of the apparatus when it is determined that the second time period elapses.Type: ApplicationFiled: December 17, 2014Publication date: December 31, 2015Inventors: Masaaki Ikuta, Hideyuki Umedu, Tadashi Tsuji

Publication number: 20150102979Abstract: According to one embodiment, an image displaying apparatus has a first and a second flat magnification display devices. These devices form a central screen. First and second mirrors are provided on a left side and a right side. First and second polarization filters alternately provided in fragmented positions in the central screen and these are different from each other in polarization direction. An image signal shaping module divides an image signal into a central and left and right regions, supplies a first image signal of the central to pixel circuits in a position of the first polarization filter, and supplies second and third image signals of the left and right to pixel circuits in a position of the second polarization filter.Type: ApplicationFiled: August 21, 2014Publication date: April 16, 2015Inventor: Masaaki Ikuta

Publication number: 20120307022Abstract: According to one embodiment, an information processor includes: a display module; a detector; a first operation receiver; a second operation receiver; a display controller; and an adjuster. The display module displays a video. The detector detects a position of a hand of an operator. The first operation receiver receives an operation from the operator with a first operation reception mode. The second operation receiver receives an operation from the operator based on a detection result of the detector with a second operation reception mode. The display controller controls the display module to display a confirmation screen to confirm that, if the first operation reception mode is to be changed to the second operation reception mode, the change of the mode. The adjuster adjusts a parameter relating to detection of position of the hand based on the detection result of the detector while the confirmation screen is displayed.Type: ApplicationFiled: March 29, 2012Publication date: December 6, 2012Inventor: Masaaki Ikuta

Patent number: 8120643Abstract: According to one embodiment, an image generator converts an input video signal to first and second divided signals to be displayed in first and second areas on one screen. First and second divided signal controllers receive the first and second divided signals, adjust the signals, and output the adjusted signals. The preparation-complete detector includes first and second frame memory groups to sequentially store a divided signal for a plurality of frames. First divided signal controller determines whether preparation to output video signals for the left and right eyes is complete or not. And First divided signal controller changes a memory selection state for reading the video signals for the left and right eyes from the first and second memory groups based on the determination indicating whether the preparation for output is complete or not complete.Type: GrantFiled: April 4, 2011Date of Patent: February 21, 2012Assignee: Kabushiki Kaisha ToshibaInventors: Masaaki Ikuta, Koji Seko

Publication number: 20030224739Abstract: There is disclosed an electronic apparatus comprising a first body including a plurality of operation keys, a second body including a display screen, and a hinge portion disposed to connect the first body to the second body so that the bodies can be pivoted. The first and second bodies can be displaced between a first form in which the bodies are folded so as to dispose the operation keys opposite to the display screen and a second form in which the bodies are opened so as to expose the operation keys and display screen. An other operation key is disposed on the second body. This other operation key is positioned between the display screen and hinge portion.Type: ApplicationFiled: May 27, 2003Publication date: December 4, 2003Applicant: Kabushiki Kaisha ToshibaInventor: Masaaki Ikuta
