Abstract: A method for showing objects in an augmented reality environment includes the steps of an Augmented Reality (AR) device obtaining spatial information and object identification (ID) from an anchor device. The AR device obtains parameters of the objects from a cloud system. The parameters of an object include the image of the object, the audio of the object, and a first spatial relationship between the object and an anchor device. The AR device obtains a second spatial relationship between the AR device and the anchor device. A third spatial relationship between the object and the AR device can be obtained according to the first spatial relationship and the second spatial relationship. The image of the object and the audio of the object is displayed or projected in the AR device according to the third spatial relationship.

Abstract: In a method for image transmitting executed in a transmitting device, three data transmitting channels are established, the three data transmitting channels are a first channel, a second channel and a third channel. An image of a video is obtained, and the image is divided into a region of interest and a background region. A first data of the region of interest and a second data of the background region are obtained, and the first data is encoded through fountain coding to obtain a third data. The first data, the second data, and the third data are respectively transmitted through the first channel, the second channel, and the third channel to a receiving device. A network condition is received, and whether the network condition matches a preset condition is determined. When the network condition matches the preset condition, the first data is compensated according to a first preset algorithm.

Abstract: A rotating controlling method for an antenna, the steps includes collecting parameters for indicating signal strength of the antenna; and determining an optimal radiation position of the antenna and setting the corresponding value of a repulsive force or an attractive force so that the antenna is rotated to the optimal radiation position.

Abstract: A method for adjusting packet length is disclosed. A first reference point currently closest to the mobile device is calculated. It is determined whether the mobile device has been updated a reference point from a server after activated. It is determined whether the cycle of updating position information has been expired if the mobile device has been updated a first reference point from the server after activated. If the cycle of updating position information has not been expired, a position as the mobile device initially enter a range of the previous reference point at an initial time and then moves to a range of the current reference point at the current time is calculated to estimate a future position of the mobile device. A future reference point of the mobile device is calculated according to the estimated future position and is updated to the mobile device and the server.

Abstract: A method for asymmetric encryption based on a gene chip includes the steps of (a) obtaining original information in text or image or other form and converting the same into a binary code, and (b) preprocessing the binary code to obtain a binary matrix. In (c), an encryption key is obtained, the encryption key comprising a gene expression solution. In (d), the gene expression solution is placed on a gene chip according to an arrangement and correspondence of the binary matrix.

Abstract: A method for adjusting packet length is disclosed. A first reference point currently closest to the mobile device is calculated. A current position of a mobile device is compared with GPS data of the first reference point to calculate brief GPS data. It is determined whether a second reference point has been uploaded to the server. It is determined whether the first reference point is identical to the second reference point if the second reference point has been uploaded to the server. The first reference point is uploaded to the server if the first reference point is not identical to the second reference point. The first reference point is uploaded to the server if the second reference point has not been uploaded to the server, and the brief GPS data is uploaded to the server.

Abstract: A charging path switching circuit includes a first port, a second port, a path switch unit, and a conversion unit. The first port is connected to an external electronic device to obtain a first electrical signal. The second port is connected to an external power source to obtain a second electrical signal. The conversion unit is connected the path switch unit and converts the first electrical signal or the second electrical signal to a predetermined voltage. The path switch unit is connected to the first port and the second port. The path switch unit selects to connect to the first port or the second port, to obtain the first electrical signal or the second electrical signal according to the connection of the first and the second port. The path switch unit preferentially selects to obtain the second electrical signal from the second port.

Abstract: A client terminal sends a signal to a wireless access device. The wireless access device receives the signal, determines channel state information corresponding to the client terminal according to identity information of the client terminal in the signal, and calculates data sent by the client terminal according to the channel state information and the signal. The client terminal sends a request signal for acquiring channel state information, wherein the request signal includes identity information of the client terminal. The wireless access device receives the request signal, obtains the channel state information corresponding to the client terminal according to the identity information of the client terminal in the request signal, and sends the obtained channel state information to the client terminal. The client terminal receives the channel state information and the signal and calculates the data sent to the client terminal according to the channel state information and the signal.

Abstract: A method for analyzing and revealing physical links in a mixed wireless and wired network applied in an access device causes the access device to generate an address resolution protocol (ARP) request packet in which a unique identifier in a target hardware address field is inserted. The ARP request packet is broadcast. The access device further receives and determines ARP reply packet transmitted by the one or more client devices. For ARP reply packets which are received from client devices, the access device generates a list of client devices which are linked with the access device.
