    Abstract: A non-removable fixed protective cover, of protective covers of a machine tool, is fitted with a light-projecting unit and a light-receiving unit, while a removable fixed protective cover and a movable protective cover are each fitted with a reflector. The light-projecting unit, light-receiving unit, and reflector are disposed so that light emitted from the light-projecting unit reaches the light-receiving unit only when the removable fixed protective cover is mounted in a proper position and the movable protective cover is fully closed.

    Abstract: Embodiments of the present invention provide a device and a method for testing transparency effect of a transparent display substrate. The device comprises a transparency identification module, an optical measurement unit and a reference object including two kinds of regions of different colors. The optical measurement unit is able to directly measure brightness of the two kinds of regions of different colors of the reference object to acquire a first brightness difference, and to measure brightness of the two kinds of regions of different colors of the reference object through the transparent display substrate to acquire a second brightness difference. Based on the first brightness difference and the second brightness difference, the transparency identification module calculates identification degree ID of the transparent display substrate according to the equation: ID = Δ ⁢ ⁢ L 2 Δ ⁢ ⁢ L 1 × 100 ⁢ % , where ΔL1 is the first brightness difference and ΔL2 is the second brightness difference. Embodiments of the present invention may eliminate the influence of ambient light on the test and increase the test accuracy of the transparent display substrate.

    Abstract: Provided are an optical receiver that can realize a reduction in the variation of sensitivity in the ultraviolet light region and a reduction in noise in the visible light region and the infrared light region, a portable electronic device, and a method of producing an optical receiver. The first light-receiving device (PD1) and the second light-receiving device (PD2) of the optical receiver (1) are each constituted by forming a second conductivity-type N-type well layer (N_well) on a first conductivity-type P-type substrate (P_sub), forming a first conductivity-type P-type well layer (P_well) in the N-type well layer (N_well), and forming a second conductivity-type N-type diffusion layer (N) in the P-type well layer (P_well). The P-type substrate P_sub, the N-type well layer (N_well), and the P-type well layer (P_well) are electrically at the same potential or are short-circuited.

    Abstract: An optical wavelength identifying system comprises an optical wavelength detecting device, a memory, a modulator, a comparison module, and an instruction module. The optical wavelength detecting device comprises a polarizer, a detecting element, a measuring device and a data processor. The polarizer is configured to transform an incident light into a polarized light. The detecting element is configured to form a temperature difference or a potential difference, wherein the detecting element comprises a carbon nanotube structure comprising a plurality of carbon nanotubes oriented along the same direction. The measuring device is electrically connected to the detecting element and configured to measure the temperature difference or the potential difference. The data processor is electrically connected to the measuring device and configured to obtain the optical wavelength by calculating and analyzing the temperature difference or the potential difference.
