Abstract: An image depth calculating device, which can calculate depth information of a binocular video with reduced computation, includes multiple modules. Modules receives a first frame information set that corresponds to a first frame time of the binocular video and establishes a first rhombic area that centers on a first pixel in a first viewing angle frame, to calculate a total pixel value of the first rhombic area. Modules further establishes a plurality of second rhombic areas that center on a plurality of second pixels of a pixel area in a second viewing angle frame to calculate a second total pixel value of each of the plurality of second rhombic areas. A depth calculating module compares the first total pixel value with each second total pixel value and calculates first frame depth information according to the result. An image depth calculating method is also provided.

Abstract: A device for recognizing control gestures and determining which one device out of a plurality is the target of control acquires images of a gesture from each electronic device. A three dimensional coordinate system for each image is established, and coordinate of a central point of each electronic device determined. Extent of gesture to the left and to the right at different depths is determined and a regression plane equation is calculated. A distance between the regression plane and center points of each electronic device is determined and the electronic device with the closest (the shortest distance) center point is determined as the target device of the control gesture. A gesture control method is also provided.

Abstract: A magnetic scanning method includes acquiring an image from a storage device of a magnetic scanning device, controlling a magnetic read-write head of the magnetic scanning device to touch a reference point on a plane, generating an electric signal which reflects relevant information of the acquired image, inputting the electric signal reflecting the relevant information of the acquired image to the magnetic read-write head, when the electric signal reflecting the relevant information of the acquired image flows through the magnetic read-write head, controlling the magnetic read-write head to generate a magnetic field corresponding to the electric signal, controlling the magnetic read-write head to move and scan the plane from the reference point, to magnetize the magnetic powder on the plane by the magnetic field, and driving the magnetic powder to move relatively to generate an image similar to the acquired image.

Abstract: A remote encryption method is executed by at least one processor of a cryptographic center. The cryptographic center connects to a sending end and to at least one receiving end. Data and a list listing at least one receiving end to which the data is to be sent are received from the sending end. A public key corresponding to the at least one receiving end listed in the received list is obtained. The received data is asymmetrically encrypted using the obtained public key corresponding to the at least one receiving end. The encrypted data is sent to the corresponding receiving end.

Abstract: The stick container includes a cup, a sleeve and a base. The cup includes a placement portion for disposing thereon a lipstick, and a spiral shell pillar extended downward from the cup. The sleeve made of a hollow tube includes a locking portion formed on the bottom portion thereof. The base includes a threaded cylinder formed in the central portion thereof. The threaded cylinder includes a threaded portion corresponding to the spiral shell pillar. A locking portion is formed in the base corresponding to the locking portion of the sleeve. The stick container is structurally simple and easy to assemble, which will largely reduce its fabrication cost.
