Abstract: A stably braking system and a method using the same control wheels on a single axle of a ground vehicle. Firstly, at least one of a wheel deceleration and an actual slip of each of the wheels is calculated. Hydraulic control commands are generated when a braking operation is performed in response to a braking indication signal and it is detected that the wheel deceleration or the actual slip is higher. The hydraulic control commands are configured to control a hydraulic braking system to adjust the wheel speed. When the ground vehicle drives in a straight line or turns with a first pose physical quantity, the hydraulic control command with a low priority is replaced by the hydraulic control command with a high priority and the hydraulic braking system is controlled to adjust the wheel speeds based on the identical hydraulic control commands.

Abstract: The present disclosure provides for managing a software function. The system determines that a service instance is to call the software function and, in response, initiates a call request for the software function to a management component The call request includes identification information and an operation parameter of the software function, with the software function shared by a service instance and at least one further service instance deployed and stored in a converged infrastructure architecture independently from the service instance and the at least one further service instance. The system receives a response to the call request from the management component, with the response including a result of execution of the software function based on the operation parameters. The system prevents the need to deploy copies of a common software function of service instances, conserving performance and storage space, and enabling more convenient maintenance, updates, and software function calls.

Abstract: A “virtual video studio”, as described herein, provides a highly portable real-time capability to automatically capture, record, and edit a plurality of video streams of a presentation, such as, for example, a speech, lecture, seminar, classroom instruction, talk-show, teleconference, etc., along with any accompanying exhibits, such as a corresponding slide presentation, using a suite of one or more unmanned cameras controlled by a set of videography rules. The resulting video output may then either be stored for later use, or broadcast in real-time to a remote audience. This real-time capability is achieved by using an abstraction of “virtual cameramen” and physical cameras in combination with a scriptable interface to the aforementioned videography rules for capturing and editing the recorded video to create a composite video of the presentation in real-time under the control of a “virtual director.
