A system, apparatus and method of improved measurement of the SPF factor of sunscreen compositions. In one embodiment, a method of measuring the protection of a sunscreen composition includes exposing skin to a known intensity of light, measuring the amount of remitted light from the skin, applying sunscreen to the skin, exposing the skin to which the sunscreen has been applied the known intensity of emitted light of the spectrum of light from which the sunscreen is intended to protect the skin, measuring the amount of light remitted from the skin, and calculating a UltraViolet-A Protection Factor (UVA-PF) of the sunscreen by comparing the amount of light remitted from the skin with the sunscreen to the amount of light remitted from the skin without the sunscreen.

A sensor cover for a rearview assembly includes a body configured for secure engagement with the rearview assembly. At least one engagement feature extends rearward and is configured for removably coupling the body with a first housing having a first predefined configuration and a second housing having a second predefined configuration.

Embodiments of this application disclose a terminal, The terminal includes a bezel, a screen, a lampshade, and a proximity light assembly. A periphery of the screen is fixedly connected to the bezel. The bezel is provided with a through hole. The lampshade is located on an inner side of the bezel and partially accommodated in the through hole. The proximity light assembly is located on the inner side of the bezel. The proximity light assembly is configured to emit emitted light into the lampshade and receive induced light passing through the lampshade. The emitted light passes through the lampshade to form emergent light. The emergent light intersects with a plane on which the screen is located. The terminal has a relatively high screen-to-body ratio.

An embodiment of this application discloses a terminal. The terminal includes a side frame, a front cover, a back cover, a display panel, and an ambient light sensor. The front cover and the back cover respectively cover two opposite sides of the side frame. The display panel is fastened to one side of the front cover facing the back cover. An outer peripheral side of the display panel and an inner peripheral side of the side frame are disposed opposite to each other and form a light-transmitting gap therebetween. The light-transmitting gap forms a first projection on the front cover. Alight sensing surface of the ambient light sensor forms a second projection on the front cover. The terminal has a relatively high screen-to-body ratio.

The disclosure provides a small photoelectric sensor that can secure a capacity for accommodating optical components and secure sealing properties. The small photoelectric sensor includes a holder in which an opening, an edge that defines the opening, and four fixing parts that are independently provided at four corners of a front surface are formed on the front surface; a cover lens that is provided at a position interposed between the four fixing parts, and is connected to the edge in a region overlapping the edge; and an optical component that is held by the holder and projects or receives light through the opening.

A system and a method for irradiating an object and potentially for controlling the irradiation or other conditions relating to an effect of the irradiation. A sensor is translated along a longitudinal direction of the radiation emitter and in a space between the radiation emitter and the objects irradiated to arrive at information relating to a parameter relating to the effect of the irradiation, such as the radiation, and derived in the space between the radiation emitter and the objects irradiated. Calibrating the sensor readings and adjusting the radiating emitter output, thereby controlling the irradiation.

The proposed concept relates to an optical sensor arrangement comprising an optical sensor with an integrated circuit arranged in or on a substrate. The substrate comprises at least a first surface area and a second surface area. At least one optically active sensor component is arranged on or in the substrate of the first surface area. The optically active sensor component is arranged for emitting and/or detecting light of a desired wavelength range. Optically inactive sensor circuitry is arranged on or in the substrate of the second surface area. A display panel comprises an active display area and a non-active display area, wherein the non-active display area comprises a material which is optically transparent in the desired wavelength range and wherein the non-active display area at least partly frames the active display layer. The optical sensor and the display panel are stacked such that, with respect to a main direction of display emission, the first surface area is arranged below the non-active display area and the second surface area is arranged below the active display area.

A sensor assembly, comprising a housing having a receiving window covered by an optically transparent cover. The housing accommodates electric components, at least comprising a motion sensor and an ambient light sensor. The motion sensor and the ambient light sensor are positioned such that light entering the cover impinges on the motion sensor and the ambient light sensor. Between the cover and the ambient light sensor is an optical diffuser positioned, such that light entering the cover traverses the optical diffuser before impinging on the ambient light sensor. The sensor assembly may be used separately or incorporated in an electric or electronic device.
