Abstract: Disclosed is a playback system including a master device and slave devices. The master device executes the following steps: selecting data for playback; obtaining the position information of the slave devices through a wireless positioning technique; ascertaining a distribution pattern according to the position information; comparing the distribution pattern with at least a part of the patterns of multiple predetermined modes and thereby selecting one from the predetermined modes as a playback mode; and determining the playback parameters of the slave devices according to the position information and the playback mode, or notifying the slave devices of their playback roles based on the playback mode and the position information to let the slave devices determine their own playback parameters. Each slave device includes a wireless communication circuit available to the wireless positioning technique, and the slave devices play synchronously according to the master device's control.

Abstract: Disclosed is a network data playback system including a network circuit, a master device, and a slave device. The network circuit is configured to provide network resources for the master device and slave device and can be included in or independent of the master device. The master device is configured to select a Uniform Resource Locator (URL) and actively/passively inform the slave device of the URL. The slave device is configured to execute the following steps: if an estimated distance between the slave device and the network circuit is shorter than a threshold, obtaining data (e.g., multimedia data) related to the URL through the network circuit and then processing the data; and if the estimated distance is longer than the threshold, searching for and/or choosing another network circuit to try to continue processing the data related to the URL through the another network circuit.

Abstract: A USB device having a circuit board, a control board, an inner housing, a outer housing and a front cover and a rear cover is provided. The circuit board has a first connector and a second connector disposed opposite to the first connector. The control board is disposed on the circuit board. The inner housing is used for receiving the circuit board and the control board. The outer housing has a front side and a rear side, and the outer housing is used for covering the inner housing. The front cover and the rear cover are disposed on the front side of the outer housing and the rear side of the outer housing respectively. By combining the control board and the inner housing, the circuit board is slidably disposed within the inner housing.

Abstract: An audio signal processing method includes the steps of: dividing an audio signal data stream into a plurality of selection segments; determining a target segment in the audio signal data stream, the target segment including a splice point for splicing a splice segment thereto; selecting one of the selection segments as the splice segment according to at least one parameter of the target segment; and processing the target segment and the splice segment to splice the splice segment to the target segment, and outputting a processed segment.

Abstract: A motion estimation method for determining a resultant motion vector. The motion estimation method includes: performing a first searching operation starting from an initial motion vector to determine an intermediate motion vector, wherein the first searching operation is performed according to a first searching principle; and performing a second searching operation starting from the intermediate motion vector, to determine the resultant motion vector, wherein the second searching operation is performed according to a second searching principle. The first searching operation is a rough search, while the second searching operation is a fine search.

Abstract: A device for preventing logging of client input data in a computer system, characterized in that it includes a first transmission interface used to connect the smart electronic device, a second transmission interface used to connect the computer system, and a data encryption chip for encryption of the input data. The data encryption chip is set between the first and second transmission interfaces and is used to encrypt data input from the first transmission interface, and then transmit the encrypted data to the computer system via the second transmission interface. The device allows for the use of a smart electronic device as a real keyboard, and the computer system permits the data encryption chip to encrypt the data input by the smart electronic device, which are then sent to the computer system, helping to prevent logging of keying data with higher efficacy and applicability.

Abstract: A hierarchical database system for on-line Chinese character recognition is disclosed. The hierarchical database system comprises: (1) the database of character description; (b) the database of stroke correspondence rules of components; (3) the database of character structures; (4) the database of standard component patterns; and (5) the database of spatial relationships between strokes of components. The database of character description stores the rule code(s) of the constituent component(s) and the character structure for all the characters included in the vocabulary. The database of stroke correspondence rules of components stores stroke correspondence rules for all the components denoted by the above mentioned rule codes. The database of character structure stores the synthesis rules of character patterns, the decomposition rules of character structures, and the spatial relationships between components, for all the 208 character structures utilized in a preferred embodiment.
