Abstract: A virtual window configuration method includes the following steps. A processor generates a virtual window. A depth detection sensor generates depth information based on an image. The processor analyzes the depth information to generate a depth matrix. The processor finds a depth configuration block in the image using the depth matrix. A feature point detection sensor generates feature point information for the image. The processor analyzes the feature point information to generate a feature point matrix. The processor finds a feature point configuration block in the image using the feature point matrix. The processor moves the virtual window to the depth configuration block or the feature point configuration block.

Abstract: The invention introduces a method for establishing a direct connection, executed by a processing unit of a first electronic apparatus, which contains at least the following steps. A first location of the first electronic apparatus and an angle of the first electronic apparatus are obtained. Second locations are collected via a communications interface of the first electronic apparatus, where each second location is of a second electronic apparatus. It is determined which of the second electronic apparatuses the first electronic apparatus is aimed at, according to the first location, the second locations, and the angle of the first electronic apparatus. A direct connection is established with the determined second electronic apparatus via the first communications interface.

Abstract: A protocol delay measuring device prevents an increase of the processing overhead of a communication terminal attributed to a protocol delay measurement. The measuring device determines the protocol delay by using first and second timestamps created respectively before and after a processed packet is obtained from an unprocessed packet by IPsec processing by the communication terminal. An acknowledges creates an identifier of the unprocessed packet. A timestamp database stores the created identifier along with the first timestamp and writes the identifier in a storage where the identifier is kept the same before and after the IPsec processing by the communication terminal. A correlator reads the identifier from the storage and extracts the first timestamp stored along with the same identifier as the read identifier in the timestamp database. A calculator calculates the difference between the extracted first timestamp and the second timestamp as the protocol delay.

Abstract: A method of displaying a picture for an electronic device with picture display function includes determining whether a resolution of a picture inputted into the electronic device is greater than a resolution of a display device of the electronic device, displaying the picture in the display device when the resolution of the picture is smaller or equivalent to the resolution of the display device, and reducing the resolution of the picture and then displaying the reduced picture in the display device when the resolution of the picture is greater than the resolution of the display device.

Abstract: A method for intercepting signals so as to change the ring mode of a mobile device includes the following steps. Initially, a signal about to enter a predetermined area is intercepted. Then, a specific ring mode is added to the signal according to contents of the signal. Next, the signal having the specific ring mode is sent to a mobile device located in the predetermined area. Subsequently, the mobile device uses the specific ring mode as the ring mode of the mobile device upon receipt of the signal. A device applying the method is also disclosed.

Abstract: A protocol delay measuring device (100) for preventing an increase of the processing overhead of a communication terminal attributed to a protocol delay measurement. The protocol delay measuring device (100) determines the protocol delay by using first and second timestamps created respectively before and after a processed packet is obtained from an unprocessed packet by IPsec processing by the communication terminal. An acknowledging section (104) creates an identifier of the unprocessed packet. A timestamp database (106) stores the created identifier along with the first timestamp and writes the identifier in a storage area where the identifier is kept the same before and after the IPsec processing by the communication terminal. A correlating section (108) reads the identifier from the storage area and extracts the first timestamp stored along with the same identifier as the read identifier in the timestamp database (106).

Abstract: In an authentication method for integrating ticket-granting service into session initiation protocol, a server provides session initiation protocol and ticket-granting services between a calling facility and a called facility, and the method includes enabling the calling facility to obtain a first ticket from the server, and subsequently issue an INVITE message containing the first ticket attached thereto to the server. If the server verifies that the first ticket be issued by the server itself, the server examines the registration status of the called facility in the server. If the status of the called facility is registered, identity authentication of the calling facility and called facility proceeds according to a predetermined ticket authentication procedure. If the authentication is successful, the called facility can establish a communication session with the calling facility.

Abstract: The present invention provides a data encryption method and apparatus, in which an encryption algorithm module combination is selected from among a plurality of encryption algorithm module combinations predetermined by the user in cooperation with data attribute matching and a dynamic selection mechanism to perform encryption processing of data. The encryption of data through such alternate use of different encryption algorithm module combinations not only enhances the complexity in decryption of the data, the processing speed is not sacrificed due to use of relatively complicated encryption algorithms to ensure security. Furthermore, in the data decryption method and apparatus according to the present invention, data is decrypted using decryption algorithm module combinations that are dynamically switched according to decryption information appended to the ciphertext.
