Abstract: A COB-typed LED light board for providing mixing light includes a substrate and a plurality of COB light bodies. The COB light bodies, which are provided on a mounting surface of the substrate, emit light with two or more different spectrums. A space distance between the adjacent two LED chips is smaller than 20 mm and is larger than a width of a single LED chip, the outer surface of a glue body which does not contact the mounting surface is provided to contact external atmosphere, and a middle portion of the glue body, formed by cohesion, is higher than a periphery portion thereof, to thus have the COB light bodies with excellent heat dissipation and an even mixing light.

Abstract: A plant growing system for growing plants. The system includes a control module, an atmospheric condition sensor module, an atmospheric condition response module, a nutrient concentration sensor probe module, and a nutrient pump module. The atmospheric condition sensor module may include: a photo sensor, a humidity sensor, and an air temperature sensor. The atmospheric condition response module may include: a lighting module, a humidifying module, a dehumidifying module, a heating module, and a cooling module. A nutrient level sensor module and a communication module are configured to communicate a detected level of water. The communication module comprises an audio communication module and a graphical user interface module. The nutrient pump module comprises: a first nutrient reservoir, a nutrient pump, a first nutrient dispersion member, a second nutrient reservoir, and a second nutrient dispersion member. There is a power module comprising a solar panel which is configured to provide energy.

Abstract: A built-in computer power-on memory test method, wherein a memory test program is built into the BIOS unit of the motherboard, immediately displays a menu on the screen at computer power-on, with the menu showing at least the commands of “Press DEL to enter SETUP” and “Press CTRL to Memory Test.” When users press the “CTRL” key, the aforementioned memory test program will be invoked, and automatically perform test to the DRAM on the motherboard, whereby quickly and accurately providing the high quality DRAM usage that is compatible with the motherboard, and thus promoting the stable operation of that computer system.
