Abstract: To provide an optical module that can synchronize a vibration frequency and a swing angle without complicating a system. An optical module including: a double-sided mirror that rotates or undergoes pendulum motion about at least one rotation axis; a plane mirror disposed at an angle of 45 degrees from a horizontal surface on a back surface side of the double-sided mirror; and a uniaxial retroreflective mirror disposed at an angle of 45 degrees from the horizontal surface on a front surface side of the double-sided mirror, in which an axis of retroreflective is perpendicular to the horizontal surface and a normal line of the uniaxial retroreflective mirror.

Abstract: A display device includes a backlight, a display element, a plate for holding at least a portion of an emission surface, from which an image light is emitted, provided on the display element, and a heat dissipation portion that dissipates heat generated from the display element. The display element is connected to the heat dissipation portion via the plate.

Abstract: The information display apparatus has a housing with an opening and a transparent cover formed on the opening, the housing includes image-light generating means configured to generate image light that displays the image information and an optical system configured to allow a driver of the vehicle to recognize image information based on the image light from the image-light generating means as a virtual image in front of the windshield. When S-polarized light on the windshield is assumed to be a first polarized wave while polarized light that orthogonally crosses the S-polarized light in a polarizing direction is assumed to be a second polarized wave, the image-light generating means is configured to generate the image light made of the first polarized wave, and a transmittance/reflectance control means blocks a part of the first polarized wave and the second polarized wave of incident external light entering the housing from the opening.

Abstract: A management information display system includes: a management state detecting unit configured to detect a placement state of an object placed on a predetermined placement area such that the object is able to be taken out; a projecting device configured to be capable of projecting a projection image onto the placement area; and a control device configured to: determine, based on a detection result from the management state detecting unit, whether or not the object has been taken out from the placement area; set projection information including information on the object that has been taken out, when the control device determines that the object has been taken out; and control the projecting device such that the projection image representing the projection information is projected onto a position where the object had been placed on the placement area.

Abstract: A garbage disposal support apparatus capable of reducing the load on a person disposing of garbage is achieved. A garbage disposal support apparatus includes: a position obtaining unit configured to obtain position information about a person having an object; an object image obtaining unit configured to obtain image information about the object that the person has; a garbage determination unit configured to check the image information about the object that the person has against garbage image information stored in a database, and determine whether the object is garbage or not; a route generation unit configured to generate route information to a disposal place of the garbage, based on the position information about the person and on disposal place information stored in the database, if the object is garbage; and a transmitter unit configured to transmit the route information to a display apparatus.
