Abstract: An image sleep analysis method and system thereof are disclosed. During sleep duration, a plurality of visible-light images of a body are obtained. Positions of image differences are determined by comparing the visible-light images. A plurality of features of the visible-light images are identified and positions of the features are determined. According to the positions of the image differences and features, the motion intensities of the features are determined. Therefore, a variation of the motion intensities is analyzed and recorded to provide accurate sleep quality.

Abstract: An optoelectronic package and a method for producing the optoelectronic package are provided. The optoelectronic package includes a carrier, a photonic device, a first encapsulant and a second encapsulant. The photonic device is disposed on the carrier. The first encapsulant covers the carrier and is disposed around the photonic device. The second encapsulant covers the first encapsulant and the photonic device. The first encapsulant has a topmost position and a bottommost position, and the topmost position is not higher than a surface of the photonic device.

Abstract: The invention discloses a non-server type voice packet communication method, which includes an IP address-inquiring step, an IP address receiving step and a voice packet-transmitting step. According to the method, the IP address-inquiring step firstly transmits an IP address-inquiring signal to a non-server type voice packet communication device using dial tones through a PSTN. Then, the IP address-receiving step receives from PSTN an IP address data transmitted from the non-server type voice packet communication device using dial tones. Finally, the voice packet-transmitting step transmits voice packets to the non-server type voice packet communication device according to the IP address data through digital network.

Abstract: A bicomponent tissue and seedling culture bottle includes an upper cover portion having an opening facing downward, and a lower container portion having a closed base and suitable for fitly but detachably connecting to the downward opening of the upper cover portion, characterized in that, a T-shaped air vent consisting of a vertical air passage centered at a top portion of the upper cover and two horizontal air passages symmetrically located at and extending from two opposite sides of the vertical air passage to be communicable with the outside air, so that air or gas produced in the culture bottle during the culture process can escape from the air vent and germs or viruses can be prevented from entering into the culture bottle when the seedlings are matured and/or are transplanted and the survival percent of the bottle cultured seedlings can be raised.
