Abstract: A display apparatus (HMD) is used by being worn by a user and includes: two lens barrels each including a closed bottom; eye cups in a barrel shape and disposed along open ends of the lens barrels; bendable temple parts that support the lens barrels by being worn by the user in an extended state; a detector that detects whether the display apparatus is worn by the user; and a drive mechanism that changes an orientation of the eye cups from a first orientation to a second orientation when the detector detects removal of the display apparatus from the user. The first orientation is an orientation which allows the user to wear the display apparatus and in which the eye cups interfere with the temple parts when bent. In the second orientation, the eye cups do not interfere with the temple parts when bent.

Abstract: An image display device for causing an optical image to be visible including: a display to emit image light; and a light guide to guide the image light from the display to an outside. The light guide has principal surfaces, including: an incident region to diffract the image to propagate inside the light guide by reflection between principal surfaces, in response to incidence of the image light from the display; and an expansion region to diffract the propagated image light to emit the diffracted image light as beams of image light from positions. The image light propagated to the expansion region has a first polarization state polarized along a direction parallel or perpendicular to a plane including a normal direction in the expansion region and a propagation direction by setting the image light incident on the incident region to have a second polarization state different from the first polarization state.

Abstract: A position estimation system includes: an obtainer that obtains image information of an image showing an indoor space in which a person is located; an estimator that estimates the coordinates of the person in the indoor space, on the basis of the image information obtained; and a position information obtainer that obtains position information of a first communication device from a positioning system. The estimator estimates the coordinates of a target first communication device held by the person, based on the coordinates of the person estimated and the position information obtained, and estimates the coordinates of an object other than the person in the indoor space, on the basis of a state of communication between a third communication device held by the object and the target first communication device, and the coordinates of the target first communication device estimated.

Abstract: A first flying capacitor circuit and a second flying capacitor circuit are connected in series so as to be in parallel to a high voltage side DC part. A reactor is connected to a positive side terminal of a low voltage side DC part and a midpoint of the first flying capacitor circuit. A midpoint of the second flying capacitor circuit is connected to a negative side terminal of the low voltage side DC part. A node between the first flying capacitor circuit and the second flying capacitor circuit is connected to an intermediate potential node of the high voltage side DC part.

Abstract: A light emitting device includes a light source and a waveguide structure. The light source emits light having a directionality. The waveguide structure includes an optical waveguide and an exterior part. The optical waveguide has an incident end surface and an emission end surface, converts a wavelength of the light incident from the incident end surface, and emits the light from the emission end surface. The exterior part is optically transparent and covers the optical waveguide such that the incident end surface and the emission end surface are exposed from the exterior part. The optical waveguide is elongated in a length direction. The length direction of the optical waveguide is inclined at a predetermined angle with respect to an optical axis of the light in a predetermined plane including the length direction of the optical waveguide and the optical axis of the light. The predetermined angle is set to allow the light to propagate in the optical waveguide with total internal reflection at a boundary surface between the optical waveguide and the exterior part.

Abstract: A light control system includes an optical reflection element and a controller. The optical reflection element includes: a reflector; and a first swing portion and a second swing portion disposed at respective one of positions sandwiching the reflector. Each of the first swing portion and the second swing portion includes: a first connection portion coupled to the reflector; a first vibration portion; a second vibration portion; a first drive portion; a second drive portion; and a second connection portion that connects the first and second vibration portions to a base. The controller causes the first and second drive portions of the first swing portion to vibrate in the same phase, and causes the first and second drive portions of the second swing portion to vibrate in the same phase but in the opposite phase to the first swing portion.
