A cover window covering a display panel of a display device comprises a base member covering a display area and a non-display area of the display panel, and an inorganic layer disposed on the base member. The inorganic layer has substantially uniform thickness on the display area, and has a diffraction grating structure on the non-display area.

An object of the present invention is to provide an I/O device, an I/O program, and an I/O method which enable easy manipulation. Another object of the present invention is to provide an I/O device, an I/O program, and an I/O method which enable easy manipulation on the basis of ergonomics. The I/O device includes a display device that can generate a stereoscopic image, a depth level sensor that measures a distance to an object, and a control unit that performs display on the display device in accordance with the depth level sensor. A detection region of the depth level sensor has a width in the depth level direction of the depth level sensor, and is composed of a curved measurement region, such that the radius of curvature on the far side in the depth level direction of the depth level sensor is different from the radius of curvature on the near side in the depth level direction of the depth level sensor.

Mounting systems can attach electronic devices a wall such as the wall of a television. Electronic devices can general a substantial amount of heat that can be trapped by mounting systems. The mount ventilation systems described herein can allow cool air to flow around electronic devices. A mounting system can include a base configured to hold the electronic device, a first ventilation channel located between a first wall and a second wall of the base, and a second ventilation channel in fluid communication with the first ventilation channel. In some embodiments, the second ventilation channel extends outward from the first ventilation channel such that the second ventilation channel fluidly couples the first ventilation channel with a portion of the mounting system configured to hold the electronic device.

A hinge unit includes a first member, a second member, a coupling member, a protrusion fixed to the first member, and a tilt stopper. When the tilt stopper is fixed at a position (P1) of the second member, the tilt stopper and the protrusion are brought into contact with each other, to thereby limit a movable range within a first angle range. When the tilt stopper is fixed at a position (P2) of the second member, the tilt stopper and the protrusion are held in non-contact with each other irrespective of a pivoting angle.

There is provided a head-mounted display, a notification apparatus, a notification system, a notification method, and a program that allow a person not wearing a head-mounted display to know that a user still continues to wear a head-mounted display after a notification that a wearing time of the head-mounted display of this user has exceeded a predetermined time. A wearing time determination block determines a wearing time of the head-mounted display of the user. A notification block executes a first notification to the user if the wearing time has exceeded a first time and, when the wearing time has exceeded a second time longer than the first time, and executes a second notification to a person not wearing the head-mounted display.

A system and method for digital black level blending is provided. The system comprises: projectors located to project respective projector images overlapping in overlap regions; at least one sensor configured to acquire digital images of at least portions of the plurality of projector images; and a computing device configured to, for each given projector: determine, using the at least one sensor, respective correspondences between projected points of a given projector image and respective points of respective image modulators of other projectors of the projectors, the correspondences representing the respective points of the respective image modulators of the other projectors that correspond to overlap regions; determine respective brightness of the overlap regions; and, control pixels of an image modulator of the projector, and each of the respective image modulators, at least adjacent edge pixels corresponding to overlap region edges, to increase brightness in corresponding projector image regions using the respective brightness.

A projection optical apparatus includes an optical system and a projection optic enclosure that accommodates the optical system. The optical system includes a first optical system on which the image light is incident, and the projection optic enclosure includes a first accommodation section that accommodates the first optical system and includes a flange section (supported section) supported by the image forming apparatus and a first wall section and a second wall section that face each other in a first direction (Y direction) that intersects the direction along a line that connects the flange section to the center of gravity of the projection optical apparatus.
