Abstract: The disclosure provides an electronic device including a housing, a light-emitting element and a light diffusion structure. The housing includes a first light-transmitting hole and a second light-transmitting hole. The light-emitting element is disposed in the housing, and is aligned with the first light-transmitting hole. The light diffusion structure includes a first light diffusion layer and a second light diffusion layer. The first light diffusion layer is disposed between the housing and the light-emitting element, and comprises a first semi-transparent region and a first light-shielding region. The first semi-transparent region corresponds to the first light-transmitting hole, and the first light-shielding region surrounds the first semi-transparent region. The second light diffusion layer is disposed between the housing and the light-emitting element, and comprises a second semi-transparent region and a second light-shielding region.

Abstract: An electronic device is provided. The electronic device includes a housing, a first light-emitting module, a second light-emitting module, and a control unit. The housing includes a first light-emitting region and a second light-emitting region. The first light-emitting module includes a plurality of first light-emitting units arranged in the first light-emitting region in an array, and the first light-emitting unit includes a light-emitting ink layer. The second light-emitting module is disposed in the second light-emitting region. The control unit is electrically connected to the first light-emitting module and the second light-emitting module, and generates a first light-emitting signal and a second light-emitting signal in response to an instruction, to respectively control the first light-emitting module and the second light-emitting module to emit light.

Abstract: The electronic device provided includes a housing with two first through holes and two second through holes, a light guiding structure, and a light source. A first section is provided between the two first through holes, and a second section is provided between the two second through holes. The length of the first section is less than the length of the second section. The light guiding structure includes a light guiding layer, a diffusion layer, and a light adjusting layer. The light adjusting layer is disposed at the position of the first section. The light source is disposed at a position that corresponds to an intersection of the first section and the second section. Light emitted by the light source passes through the light transmitting portion and the intersection, and is separately emitted through the first through holes and the second through holes along the light transmitting portion.

Abstract: A novel Ultra-trace Automatic Mercury Species Analyzer (AMSA) is a semi-automatic or automatic on-line dual-channel detection device. The principle of the methodology is on-line coupling of analytical stages (or set-ups) with cold vapor atomic detector using flow injection analysis technique. This analyzer can be fully automatic for fast and accurate monitoring Hg species of natural environmental samples in ultra-trace levels. Furthermore, the AMSA is well suitably used in laboratory or other field stations (e.g., shipboard uses etc.) It provides ease of operation, fast analysis, high analytical performance, and excellent data quality. There is no risk of contamination with ambient air and no need of ultra-clean class-100 room to obtain the high quality data on ultra-trace mercury species analyses (e.g., Hg0, Hg2+, monomethyl Hg, dimethyl Hg etc.) in natural environmental samples (e.g., air, water, sediment, soil, vegetation, bio-tissues and other sample types).
