Abstract: A boarding information reminding system includes a client system applied in an electronic device and a back-end system applied in a back-end host. the client system receives ticket information and reminder information registered by a client. The back-end system queries up-to-date information of a flight according to the ticket information, and transmits the up-to-date information to the client system. When it is departure time, the client system reminds the client to leave for the airport and continuously transmits position information of the client to the back-end system. The back-end system compares the position information of the client with the position information of the boarding gate, compares current time with the boarding time of the flight, to determine if the client can reach the boarding gate in time. If the client cannot reach the boarding gate in time, the back-end system sends alarm information to the client system.

Abstract: A method for monitoring a target area using a video monitor device that controls a video camera located at the target area to capture left images and right images of the target area. The video monitor device analyzes each of the left and right images to form a combined image, compresses all of the combined images to generate compressed images, and stores the compressed images into a storage system. When an event happened in the target area, a compressed image corresponding to the event time is obtained from the storage system. The video monitor device decompresses the compressed image to generate a 3D image of the target area, and displays the 3D image on a display device.
