Abstract: A door-lock control method adopted by a door-lock device and a computer program is present. The method comprises: broadcasting a connecting message in a WPAN at the door-lock device; controlling a mobile device to establish a connection with the door-lock device via the WPAN when receiving the connecting message at the computer program; sending an unlocking command via the connection at the computer; and unlocking a door-lock thereon when receiving the unlocking command at the door-lock device. This application can omit the operations which the householder needs to do manually on the mobile device or the door-lock device, and effectively improves the convenience of use and reduces the waiting time of completing unlocking the door-lock.

Abstract: A remote access control system comprising a remote host connected to a mobile device, a proximity sensor doorbell, a door lock device and a gateway device is provided. The proximity sensor doorbell triggers a doorbell signal when sensing a finger of a visitor approaches. The gateway device sends a first notification message to the mobile device via the remote host when recognizing that a captured monitoring video comprises image of the visitor, sends a second notification message to the mobile device via the remote host when receiving the doorbell signal, and controls the door lock device to unlock when receiving an unlocking message from the mobile device. This system facilitates the householder to control the entry remotely and effectively reduces the probability of doorbell failing.

Abstract: Systems and methods for obtaining camera parameters from images are provided. First, a sequence of original images associated with a target object under circular motion is obtained. Then, a background image and a foreground image corresponding to the target object within each original image are segmented. Next, shadow detection is performed for the target object within each original image. A first threshold and a second threshold are respectively determined according to the corresponding background and foreground images. Each original image, the corresponding background image, the first and second threshold are used for obtaining silhouette data and feature information associated with the target object within each original image. At least one camera parameter is obtained based on the entire feature information and the geometry of circular motion.

Abstract: Software attributes assigned to graphical objects of a graphical program are automatically reapplied to graphical objects of a modified version of the graphical program to enable concurrent graphical program development and automatic code generation. Changes between original and modified versions of graphical program are ascertained and software attributes from objects of the original version are copied to objects of the modified version where appropriate. Unique static identification codes are assigned to the objects of the original and modified graphical programs, and are used as a basis for determining if the software attributes from the original version can be applied to the objects in the modified version.
