Abstract: A method for primary-backup server switching. A control server monitors whether a primary server fails. The control server is in communication connection with the primary server and a backup server. The primary server is provided with a primary memory database. The primary memory database is configured to save in real time state information of the primary server each time after an operation is executed, and the state information is read and saved in real time by a backup memory database in a backup server. In response to a failure of the primary server, the control server sends a primary-backup switching command to the backup server. The primary-backup switching command is configured to instruct the backup server to upgrade itself to become a new primary server according to the state information saved in the backup memory database.

Abstract: Various embodiments of a vision-based privacy-preserving embedded fall-detection system are disclosed. This embedded fall-detection system can include one or more cameras for capturing video images of one or more persons. Moreover, this embedded fall-detection system can include various fall-detection modules for processing the captured video images including: a pose-estimation module, an action-recognition module, and a fall-detection module, all of which can perform the intended fall-detection functionalities within the embedded system environment in real-time in order to detect falls of the one or more persons. When a fall is detected, instead of sending the original captured images, the embedded fall-detection system can transmit sanitized video images to the server, wherein each detected person is represented by a skeleton figure in place of the actual person images, thereby preserving the privacy of the detected person.
