Abstract: An optical fiber transmission device includes a substrate, a photonic integrated circuit, and an optical fiber assembly. The photonic integrated circuit is disposed on an area of the substrate. The substrate has a protruding structure at an interface with an edge of the photonic integrated circuit. The optical fiber assembly includes an optical fiber and a ferrule that sleeves the optical fiber. The protruding structure of the substrate is configured to abut against the ferrule to limit the position of the optical fiber assembly in a vertical direction of the substrate, such that the protruding structure is a stopper for the optical fiber assembly in the vertical direction.

Photonic integrated circuit includes a laser chip, a photodetector, a wavelength division multiplexing coupler, a first optical modulation element and a second optical modulation element. Laser chip is disposed on photonic integrated circuit, and is configured to generate first optical signal. Photodetector detects second optical signal. Wavelength division multiplexing coupler is configured to couple first optical signal to fiber, and receives second optical signal. First optical modulation element is coupled to wavelength division multiplexing coupler and laser chip, and is configured to modulate first optical signal.

Abstract: An automatic target image acquisition and calibration system for application in a defect inspection system is disclosed. During the defect inspection system working normally, the automatic target image acquisition and calibration system is configured to find a recognition structure from an article under inspection, and then determines a relative position and a relative 3D coordinate if the article. Therefore, a robotic arm is controlled to carry a camera to precisely face each of a plurality of inspected surfaces of the article, such that a plurality of article images are acquired by the camera. It is worth explaining that, during the defect inspection of the article, there is no need to modulate an image acquiring height and an image acquiring angle of the camera and an illumination of a light source.

Abstract: The invention relates to a method of manufacturing conjugated diene-based polymers. The conjugated diene-based polymers are obtained by polymerizing conjugated diene monomers or conjugated diene monomers and vinyl aromatic monomers using an initiator, wherein the initiator is obtained by reacting a divinylarene-like compound represented by the formula (1) with an organic alkali metal; A and B are CnH2n+1 or an aromatic ring, n is 0~5, A and B can be the same or different, and Q is an aromatic ring; wherein the molar ratio of the divinylarene-like compound to the effective active organic alkali metal is 1.3-5.0. The present invention further relates to a rubber comprising the conjugated diene-based polymers, and a tire comprising the rubber.

Abstract: A system for acquiring multi-angle images of a product includes a workstation having a working surface for placing a product, a camera supporting member having a vertical axis, and an image capturing device movably attached to the camera supporting member so that it may move along the vertical axis of the camera supporting member.

Abstract: Method and apparatus of video coding using decoder derived motion information based on bilateral matching or template matching are disclosed. According to one method, an initial motion vector (MV) index is signalled in a video bitstream at an encoder side or determined from the video bitstream at a decoder side. A selected MV is then derived using bilateral matching, template matching or both to refine an initial MV associated with the initial MV index. In another method, when both MVs for list 0 and list 1 exist in template matching, the smallest-cost MV between the two MVs may be used for uni-prediction template matching if the cost is lower than the bi-prediction template matching. According to yet another method, the refinement of the MV search is dependent on the block size. According to yet another method, merge candidate MV pair is always used for bilateral matching or template matching.
