Abstract: An object is to provide a mobile electronic device with high operability and high safety. The mobile electronic device includes an image projector that projects an image, a control unit that controls a projection operation by the image projector, and a cabinet that supports the image projector and the control unit. The control unit can select a first mode and a second mode, and controls an operation of the image projector, when the first mode is selected, in a condition different from that when the second mode is selected.

Abstract: A method is provided. A command to correspond to a target speed of a motor is received. A rotational speed of the motor is measured, and a brake-to-off ratio for a braking interval is calculated based at least in part on the rotation speed, the target speed, a braking parameter. An off state for an inverter that is coupled to motor is induced during an off portion of the braking interval, and a brake signal is applied to the inverter during a braking portion of the braking interval.

Abstract: According to an aspect, an electronic device includes a first touch sensor, a second touch sensor, and control unit. The first touch sensor detects a contact in an active state. The second touch sensor detects a contact in a sleep state with a power consumption lower than that of the first touch sensor. The control unit switches from the sleep state to the active state when a contact is detected by the second touch sensor.

Abstract: According to an aspect, a portable photographing device includes: an image capturing unit; a projecting unit for projecting an image; and a storing unit for storing an image captured by the image capturing unit. The projecting unit projects any of a first image captured by the image capturing unit, a second image related to the first image, and a third image obtained by synthesizing the first image with the second image as a projection image into a region which is different from an image capturing region of the photographing unit. The storing unit stores the first image in the projection of the projection image or the first image after the projection of the projection image.

Abstract: According to an aspect, a projector device includes an image projecting unit and a control unit. The image projecting unit projects an image. The control unit acquires brightness information of regions included in a projection surface on which the image projecting unit can project the image, and causes the image projecting unit to project, based on the brightness information of the regions, the image on a low-brightness region, among the regions, whose brightness is lower than that of another region.

Abstract: According to an aspect, an image projecting apparatus that projects an image includes a light source, a light emitting port, an emitting unit, and a control unit. The emitting unit causes the light emitted from the light source to be emitted from the light emitting port in such a manner that an emission direction of the light emitted from the light source can be varied. The control unit controls the light source and the emitting unit to switch between a first projection mode and a second projection mode. When the image projecting apparatus is placed on a horizontal plane, the emission direction is a front direction of the light emitting port or obliquely upward with respect to the horizontal plane in the first projection mode, and the emission direction is obliquely downward with respect to the horizontal plane in the second projection mode.

Abstract: A mobile electronic device 10 includes a projector 34, a camera 36, and a processing unit 22. The projector 34 projects an image, and the camera 36 captures the image projected by the projector 34. Based on first image information for causing the projector 34 to project a predetermined image and second image information obtained by capturing the image projected by the projector 34 based on the first image information by the camera 36, the processing unit 22 determines whether the projector 34 projects the predetermined image. When determining that the projector 34 fails to project the predetermined image, the processing unit 22 suppresses output of the projector 34 for projecting the image.

The mobile electronic device includes an image projector that projects an image, a control unit that controls the operation of the image projector, a cabinet that holds the image projector and the control unit, and an acceleration sensor that detects an acceleration acting on the cabinet. The object is achieved in such a manner that when an acceleration of a given value or more is detected by the acceleration sensor, the control unit stops emission of light from the image projector or reduces an amount of light emitted from the image projector.

Abstract: It is a task to provide a mobile electronic device with high operability and high safety. The mobile electronic device includes an image projector that projects an image, a detector that detects a specific change in an irradiation area of light irradiated from the image projector or in a predetermined area including the irradiation area, and a control unit that controls the operation of the image projector. The task is solved in such a manner that when the detector detects the specific change, the control unit causes the image projector to stop emission of light therefrom, or to reduce an amount of light emitted therefrom.

Abstract: A roll used for tensioning a canvas belt used to hold paper against a dryer. The roll includes a main cylindrical body formed of steel. A layer formed of a metal harder than steel is disposed over the outer surface of the main body. The metal layer is formed with a channel around its center so as to define two spaced roll end sections of a common diameter. A fluororesin layer is disposed in the metal layer channel and is shaped so as to have an outer surface of a diameter equal to that of the metal layer end sections.
