Abstract: A meter receives a new communication frame from a power line, and determines whether the new communication frame is used to read power consumption of the meter. If the new communication frame is used to read power consumption of the meter, the meter generates a response frame of the new communication frame, and broadcasts the response frame to the concentrator via the power line to report the power consumption of the meter. If the new communication frame is not used to read power consumption of the meter, the meter broadcasts the new communication frame to the at least one other meter and the concentrator via the power line.

Abstract: In a method for establishing a dial up connection between a terminal device and a server, an inquiry packet is sent from the terminal device to a router to request parameters for establishing the dial-up connection when the terminal device dials the server. The terminal device monitors a response packet sent by the router and obtains the request parameters from the response packet, then the terminal device dials the server and sends a dial-up request packet to the server. The server assigns network connection information for the router when the dial-up request packet is received. After monitoring a feedback packet sent by the server, the terminal obtains the network connection information from the feedback packet, and updates configuration parameters of the router to establish the dial-up connection according to the network connection information.

Abstract: A method and system for providing conditional access (CA) between a headend and a receiver include scrambling media data of broadcast programs and encrypting control words according to a CA system used on the headend. The receiver includes a CA virtual machine. The receiver receives the broadcast program and encrypted control words, and determines whether the media data is scrambled. If the media data is scrambled, the CA virtual machine runs a CA instance matched with the CA system, gets entitled manage message (EMM), and determines whether CA algorithm identifier in the EMM matches with CA algorithm identifier of the CA instance. If the CA algorithm identifiers match, the encrypted control words are decrypted and the scrambled media data is descrambled. If the CA algorithm identifiers do not match, updated CA algorithm is downloaded and the CA instance which has updated its CA algorithm is run.

Abstract: In a router and a method of passing IPv6 data packets through the router, the router receives a data packet from a local area network or the wide area network. The router determines if the data packet is a IPv6 data packet or a non-IPv6 data packet . The router routes the data packet to a destination address via the network layer of the open system interconnect, upon the condition that the data packet is a non-IPv6 data packet; or bridges the data packet to the destination address via the data link layer, upon the condition the data packet is a IPv6 data packet.

Abstract: A wireless terminal roams from a first access point to a second access point. The wireless terminal can set a predetermined time period to determine whether to roam between different access points. Upon receiving signals from the second access point, the wireless terminal decodes signals received from the first access point and the second access point to get a correct probability of each bit of the signals. The wireless terminal then calculates mean values, a variance value and a difference in the mean values of the first access point and the second access point. If the difference in the mean value exceeds a product of the variance value and a roaming weight, the wireless terminal switches the wireless terminal from the first access point to the second access point to access the network.

Feature data v of the image B are extracted in the similar way. A similarity of a grayscale density Vak selected from the feature data u and the grayscale density Vbk selected from the feature data V, is computed. Thus, n similarities are computed. A similarity ? (n, u, v) of the image A and the image B according to the n similarities.

Abstract: A set top box transmits a connection request to a TV to request a number of response signals therefrom. The response signals are read when the TV is in a working state, and an idle signal is output if the response signals are not read in a predetermined time. State of the TV is determined according to the response signals or the idle signal, and the set top box is controlled to be in the working state according to the starting signal, or placed a sleeping/standby state according to the standby signal.

Abstract: In a voice-controlled navigation device and method, a voice command is received, and divided into voice segments Vi (i=1˜n) by comparing with one or more keywords. A voice segment Vi (i=1˜n) is obtained in sequence to be compared with tree nodes in a search tree of place names. A weight value of each tree node is computed according to a comparison, to select one or more tree nodes whose weight values are greater than a predetermined value. Routes formed by all the selected tree nodes are obtained to select a route whose total weight value is the greatest. A navigation to a destination is given by indicating the selected route on an electronic map according to place names represented by the tree nodes of the selected route.

Abstract: A network device transmits and receives data packets between the network device and a network. The data packets includes information about a procedure needed in order to process the data packets. According to the information, the network device executes the procedure to process the data packets. If the time of the procedure has not been executed to process the data packets is more than a predetermined time and no other data packets are needed to be processed, the network device turns off the procedure automatically.

Abstract: In a voice recording equipment and method, voice data from a speaker is received using a microphone. Threshold values T1 and T2 of surrounding environment of the voice recording equipment are determined. If an intensity of the voice data is less than or equal to the threshold value T2, the voice recording is stopped and the speaker is informed that the voice data is not useful. If the intensity of the voice data is greater than the threshold values, the voice data is stored into a storage unit.
