Systems and methods for offline content provisioning
A global architecture (GLP), as disclosed herein, is based on the thin server architectural pattern; it delivers all its services in the form of web services and there are no user interface components executed on the GLP. Each web service exposed by the GLP is stateless, which allows the GLP to be highly scalable. The GLP is further decomposed into components. Each component is a microservice, making the overall architecture fully decoupled. Each microservice has fail-over nodes and can scale up on demand. This means the GLP has no single point of failure, making the platform both highly scalable and available. The GLP architecture provides the capability to build and deploy a microservice instance for each course-recipient-user combination. Because each student interacts with their own microservice, this makes the GLP scale up to the limit of cloud resources available—i.e. near infinity. |

Icosahedral LED display screen
An icosahedral LED display screen belongs to the field of display screens and includes multiple cabinet main frames. Each cabinet main frame is formed with an accommodating cavity. A side of each cabinet main frame is provided with a flexible PCB, an outer side of the flexible PCB is disposed with LEDs, and an inner side of the flexible PCB is provided with a magnet fixedly therewith. The multiple e.g., twenty cabinet main frames are mutually connected to form an icosahedral sphere which has no end point similar to a football, and polygons that make up the sphere are the same, and therefore the cabinet main frames can be completely covered by the flexible PCBs to eliminate a missing of display at an endpoint and reduce design numbers and complexities of the cabinet main frames and the flexible PCBs. An installation of the LED display screen becomes more convenient. |
