Abstract: Embodiments of the present disclosure provide a solution for visual data processing. A method for visual data processing is proposed. The method comprises: performing a conversion between a bitstream of a current frame of visual data and at least one packet in accordance with a real-time transport protocol (RTP), wherein the at least one packet comprises a first indication indicating a difference between a decoding timestamp of the current frame and a presentation timestamp of the current frame.

Abstract: A non-programming platform consisting of modules (functions) is created for matrix and vector operations in linear algebra. Each module appears to be a typical math function and can carry out a class of distinct matrix and vector operations. By taking a short line of user input at interface, each module can be applied separately or along with other modules and math functions as well as their combinations and compositions for various matrix operations. For an intended operation, users only need to write a short line of self-explaining input, which is required to write in math language, in a logic order, and appear to be human readable math expressions and functions. This platform enables users to have the common functionalities in most matrix calculators and computer algebra systems, so they can focus on learning essential concepts and relations in linear algebra instead of on programming commands and syntax.

Abstract: A non-programming user interface consisting of modules (functions) provides a tool for computing and graphing math expressions. By taking user input at interface, each module can be applied separately or along with other non-graphing modules and math functions for calculations from simple to complicated math operations (e.g., differentiation, integration, or their composition), depending on needs and appropriateness of function combination and composition. For an intended operation, users only needs to write a short line of self-explaining input at interface, which include three-character module names, and some necessary math elements such as expressions of functions or equations, variables, choices of values, and optional two-character keywords and related values. This interface enables users to have functionalities in common computer algebra systems, and meanwhile can focus on essential math elements and concepts instead of programming commands and syntax.

Abstract: A contact system employs a swing link (1) to drive set of movable contacts (5) to engage with a left or right set of contacts (24, 25) respectively on two sides thereof, so as to achieve indication of a separate or closure position. Particularly, a drive shaft (2) along with an operating plate (3) and a snap plate (4) on the drive shaft (2) are driven by the swing link (1) to change a motion trajectory of a roller (10) on a movable contact shaft (12), aided by action of a snap-action claw (11) and a tension spring (9), thereby achieving, quick action of set of movable contacts (5), and realizing a contact with or disconnection from set of fixed contacts (6) to achieve indication of the separation or in closure position. The system has a simple structure and a small size, responds quickly and accurately, and is cheap to manufacture, install, and maintain.
