Abstract: The present invention relates to a plant growth identification method and a system therefor. At least one photographing unit transmits a picture captured thereby to a control unit so as to calculate the pixel distance per unit, and then the photographing unit captures a picture of a plant so that features points of the plant such as buds, flowers, or fruits in the captured picture are identified with the control unit, the pixel distance of each feature point and the height thereof are then calculated with the control unit, and the number and area of the multiple feature points are counted so as to calculate the growth rate and yield of the plant. Moreover, data such as growth height, rate and yield of the plant is regularly updated so as to dynamically adjust the light intensity of a lighting unit on the plant.

Abstract: A scroll-rotation prevention assembly of a scroll compressor includes a fixed scroll, an orbiting scroll and an Oldham ring. The fixed scroll is positioned in the compressor and has a body. Two blocks extend from the periphery of the body. The orbiting scroll is disposed to correspond to the fixed scroll and has a main body. Two protrusions extend from the periphery of the main body. The Oldham ring is sandwiched between the body of the fixed scroll and the main body of the orbiting scroll. The Oldham ring has a first surface provided with a pair of first troughs and a second surface opposite to the first surface. The second surface is provided with a pair of second troughs. Each protrusion is slidably connected in the first troughs. Each block is slidably connected in the second troughs. Thus, the wear of the Oldham ring can be reduced.
