Abstract: A small-scale robotic arm joint and a robot thereof are provided. In the small-scale robotic arm, multiple bearings are arranged at both ends and middle of a motor shaft; a sliding seal member is provided between a harmonic reducer and a motor; seal members are fitted on contact surfaces between a circular spline and a housing, as well as between the circular spline and the output end; a control board and the output end are hollow structures, through which cables pass; a magnetic coder is adopted to reduce a volume of the joint; additionally, a magnetic shielding plate is provided on the housing that separates the motor and the control board. Robotic arms of a robot are connected using said small-scale robotic arm joints, which are compact, smooth-operating, and safe, improve stability of a rotational axis, and prevent lubricating grease from entering the motor interior or the control board.

Abstract: A method for generating massage tracks includes acquiring two-dimensional data of preliminary massage point positions according to a user-selected massage mode; acquiring point cloud data of a region to be massaged of a target object; acquiring the massage point position two-dimensional data of the target by proportion calculation according to the preliminary massage point position two-dimensional data and the point cloud data of the region to be massaged of the target object; acquiring three-dimensional massage point position data of the target according to the two-dimensional data of the massage point position of the target and the point cloud data of the region to be massaged of the target object; and generating a final massage track based on a preset massage track planning algorithm according to the three-dimensional massage point position data of the target. The present application may select a massage mode to improve individual adaptability.

Abstract: Aspects of the present disclosure relate to providing a shoppable video corpus by generating a shoppable URL. A URL is extracted from a video corpus, in which the extracted URL may be a long URL or a short URL. Extracted URLs are then combined and normalized. From the normalized URL, noise is removed and quality control is performed. As a result, shoppable URL may be presented at the user's computing device as personal recommendation. The video and metadata of the cleaned URL is also ingested and stored in a database for future reference.

Abstract: A nonaqueous cell employing an anode such as lithium or lithium alloy, a liquid lithium salt nonaqueous electrolyte, a thermal shutdown separator and a cathode comprising a homogeneous hybrid mixture of carbon fluoride and manganese dioxide, said carbon fluoride or poly-carbon fluoride being represented by the formula (CFx) wherein 0.5?x?1.2 and contained in said mixture in a ratio by weight of about 5 to 99%, preferably about 5 to 50% and said manganese dioxide is heat treated electrolytic manganese dioxide represented by EMD or MnO2. The CFx—MnO2 hybrid cathode cells yield high capacity with high discharge rate and excellent low-temperature performance without voltage delay. The cells are characterized by two significant plateaus in their discharge profiles, the first contributed by MnO2 and the second by CFx.

Abstract: The present invention provides mesostructural metal oxide materials that can be employed in lithium ion rechargeable batteries as intercalation electrodes. The mesostructural metal oxide materials of the present invention maintain their structural integrity during intercalation, are reversible and exhibit increased electrochemical capacity. The use of such mesostructural metal oxides in rechargeable batteries is also described herein.
