An inner end of the lower tie rod is connected to the frame and an outer end of the upper tie rod is mounted at the rear end of the trailing arm. The lower tie rod is located below the upper tie rod. An included angle between the upper tie rod and the lower tie rod being a, and a satisfies a relationship: 0°<a<5°.

Abstract: An electrode plate extension device includes a first roller and a second roller. The first roller includes a first body and a protrusion. The protrusion is provided on an outer peripheral surface of the first body and extends in a circumferential direction of the first body. The second roller includes a second body and a groove. The groove is provided in an outer peripheral surface of the second body and extends in a circumferential direction of the second body. The first roller and the second roller are arranged in parallel, a gap for allowing an electrode plate to pass is formed between the first roller and the second roller, the protrusion is positioned corresponding to the groove, and the protrusion is configured to press against an uncoated region of the electrode plate to cause a plastic deformation of the uncoated region.

Abstract: A lane detection method integratedly using image enhancement and a deep convolutional neural network. On the assumption that lanes have similar widths in a local region of an image and a lane can be segmented into several image blocks, each of which contains lane marking in the center, a method based on a deep convolutional neural network is provided to detect lane marking blocks in the image. Input to the model includes road images captured by a camera as well as a set of enhanced images generated by the contrast limited adaptive histogram equalization (CLAHE) algorithm. The method according to the present disclosure can effectively overcome difficulties of lane detection under complex imaging conditions, such as poor image quality, and small lane marking targets, so as to achieve better robustness.

Abstract: A method relating to image compression includes acquiring image data of an image, wherein the image includes a matrix of pixels, and the image data include pixel values of the matrix of pixels. The method also includes generating, based on the image data, a first-level data set including pixel values of a portion of the matrix of pixels. The method further includes determining at least one coding mode for the first-level data set, encoding the first-level data set into a code stream based on the at least one coding mode, and packaging the code stream into a modified code stream.

Abstract: A sled carriage is configured to move in a direction of an axis. A platform is attached with the sled carriage and a sled buck is attached with the platform. Upon acceleration of the sled carriage, the sled buck and platform move relative to the sled carriage.

Abstract: A side airbag for an automotive vehicle includes an outboard panel having a perimeter edge and a first vertical length, and an inboard panel having a perimeter edge and a second vertical length shorter than the first vertical length, the inboard and outboard panels joined to one another around their respective perimeter edges to form an enclosed volume such that when the airbag is inflated a mid-thickness line is concave toward the inboard panel. When the inflated airbag is positioned between an occupant seat and a side wall of the vehicle, the inboard-curved shape provides early engagement between an occupant of the seat and the airbag to offer improved protection for the head and neck.
