Abstract: An image display system includes a body, a first correction unit, and a second correction unit. The body houses a display unit to display an image and projects a virtual image, corresponding to the image, onto a target space using outgoing light of the display unit. The first correction unit corrects for distortion of the image. The second correction unit corrects a display location of the image on the display unit in accordance with an orientation signal representing a change in orientation of the body. Each of divisional areas of a display screen of the display unit is assigned with a distortion correction parameter for correcting for the distortion of the virtual image. The first correction unit applies distortion correction to each of the image regions of the image on the display screen based on a distortion correction parameter assigned to a divisional area where the image region is displayed.

Abstract: 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.

Abstract: According to one embodiment, an information processing apparatus includes a wireless communication module including an event notifier, an embedded controller and a setting module. The embedded controller registers event information configured to indicate that supply of electrical power to the wireless communication module was cut in a register and turns on the apparatus, when the embedded controller is started or reset. The setting module sets the wireless communication module to enable the event notifier, if the event information is registered in the register of the embedded controller when the apparatus is turned on.

Abstract: According to one embodiment, an electronic device includes a port, an acquisition controller and a controller. The port is connectable to an extension unit with a keyboard. The acquisition controller is configured to acquire first information from the extension unit connected to the port. The controller is configured to control an operation of the device based on the first information acquired by the acquisition controller.

Abstract: An electronic apparatus includes a display module, a touch panel, a password input receiving module and a password display module. The touch panel is provided overlaying on the display module. The password input receiving module receives a password input through the touch panel. The password display module moves and displays keys while inputting a password on a password entry screen on which a group of the keys for identifying a password to be input is displayed.

Abstract: According to one embodiment, an information processing apparatus includes a main body, a display portion configured to freely open and close with respect to the main body, and a notification module. The notification module is configured to generate a notification when an opening angle of the display portion respect to the main body exceeds a threshold value.

Abstract: According to one embodiment, a storage stores secret data, first identification data, and a first random key. A generation module generates first authentication data from the secret data, first identification data, and second identification data of a removable medium. A first verification module determines whether the first authentication data and second authentication in the removable medium are identical. A second verification module determines whether the first random key and a second random key in the removable medium are identical, if the first and second authentication data are identical. An activation module activates the data processing apparatus if the first and second random keys are identical.

Abstract: Part of compressed air discharged from a compressor is cooled by a cooler, and merged with a working fluid for a turbine to cool rotor blades of the turbine. Further, air from the compressor is bled through introduction passages, and the bled air is cooled by coolers and introduced to stationary blades of the turbine. The stationary blades of the turbine are cooled with air cooled by the coolers. A sufficient cooling effect is obtained by a small amount of air, and the amount of compressed air bled through the introduction passages is decreased. Compression power is converted into turbine output effectively.

Abstract: Using fuel and air introduced for working a power generation portion 20, cooling of the power generation portion 20 is performed in a reaction gas heat exchanger 24. This obviates the necessity for separately introducing air for cooling, and only compressed air necessary for working is introduced. Thus, the power of an air pressure feed source for a fuel cell apparatus is cut down, and a power generation output relative to the amount of air is increased. Consequently, the electric output/efficiency of the fuel cell apparatus and the output/efficiency of power generation equipment are increased.
