Abstract: Scene aware video content encoding techniques can determine if video content is a given content type and is one of one or more given titles that include one or more given scenes. The one or more given scenes of the video content of the given type and given one of the titles can be encoded using corresponding scenes specific encoding parameter values, and the non-given scenes can be encoded using one or more general encoding parameter values. The one or more given titles can be selected based on a rate of streaming of various video content titles of the given type.

Abstract: Mechanical fingers for clamping catheters, guild wires, and the like equipment for vascular intervention include a left clamping panel, a right clamping panel, left gathering pieces, right gathering pieces, a linear-propelling mechanism, and a frame. The linear-propelling mechanism is arranged on the frame. The left clamping panel and the right clamping panel are oppositely arranged, and are each arranged on the linear-propelling mechanism. The left gathering pieces and the right gathering pieces are arranged on the left clamping panel and the right clamping panel, respectively. The linear-propelling mechanism drives the left clamping panel and the right clamping panel to move towards or move away from each other. The mechanical fingers can realize adaptive clamping for intervening equipment in a widely varying diameter range. The clamping surfaces of panels in the mechanical fingers are provided with grid-and-stripe microstructures and are made from resilient materials.
