Abstract: A release latch includes a latch mechanism. The latch mechanism has a base, and an arm. The arm has one end attached to the base, and a free end. The latch mechanism further has a catch connected to the free end of the arm. The base is adapted to be attached to a first component, and the catch is adapted to releasably engage a second component to releasably hold the first component against the second component. The release latch further includes a release mechanism adapted to be attached to the first component, and being movable relative to the base. When the release mechanism is moved, the release mechanism engages the arm to move the arm, thereby causing the catch to disengage from the second component and allowing the first component to be moved away from the second component.

Abstract: A compact optical apparatus for use in optical communication is provided which can be manufactured at low costs with ease. A common terminal is mounted to receive diverging light with a long wavelength and to output light with a short wavelength, and an input terminal is mounted to receive light with a short wavelength. An output terminal is mounted to transmit light with the long wavelength to a light receiver. A wavelength selecting filter permits the light with the long wavelength to pass to the light receiver and reflects light transmitted from the input terminal so as to selectively direct it to the common terminal. First and second computer-generated hologram devices guide diverging light from the input terminal to the common terminal via the wavelength selecting filter.

Abstract: A rotating display to present images includes a transmission/support mechanism installed on a column of a building, an annular display unit installed around the column, supported and driven by the transmission/support mechanism, a contact power supply unit installed on the column, a control unit provided inside the display unit, and an angle encoding unit between the column and the display unit. Using the foregoing elements, a rotating display can be formed on a column of a building. Image signals are transmitted wirelessly to the control unit to light up the light-emitting modules on the display unit. Due to the visual persistence in human vision, a 360-degree panoramic image can be produced, thus decorating the building column or playing commercials.
