A universal serial bus (USB) connector includes a case, an insulation tongue, a first row of electric coupling pins mounted to top surface of the installation tongue, and a second row of electric coupling pins mounted to bottom surface of the insulation tongue. Each row of electric coupling pins are spaced in a horizontal direction of the insulation tongue. The electric coupling pins mounted on the top surface of the insulation tongue and the electric coupling pins mounted on the bottom surface of the insulation tongue are reversely and symmetrically arranged by type. The insulation tongue is movable along a vertical direction by deforming the electric coupling pins. The insulation tongue is movable along a vertical direction by deforming the electric coupling pins. An electronic device includes a main body and the USB connector installed to the main body.

The present invention relates to a method and an apparatus for providing internal server. The method comprises: matching relevant information carried by a message exchanged between an internal network and an external network with corresponding relationship information between external characteristic information and internal characteristic information of the internal server configured in a mapping table, wherein the external characteristic information comprises an external address and an external port of the internal server, and the internal characteristic information comprises an internal address and an internal port of the internal server; and processing the message according to a matching result. According to the present invention, WEB server and FTP server in the LAN can be easily provided without occupying too much valid IP addresses, thus, the present invention saves limited public IP addresses resource. Furthermore, the present invention implements port-level support to the internal server, and guarantees the security of network equipments.

摘要:
Wireless personal area network (Zigbee, Bluetooth, UWB) and wireless identification technologies (Near Field Communication (NFC), Radio Frequency Identification (RFID)) are implemented in particular client server functions and communications. Connected with an Authentication Server, a wireless HUB authenticates user identification and provides the user with access to secure data communication with a wireless terminal such as a cellular phone or a PDA. A Location Server provides user locations via methods such as RSSI, TDOA, and GPS and sends location information to a Center Control Server and the Authentication Server. With location information, the Center Control Server initiates and optimizes secure information processes and coordinates the functions of servers and user terminals.

A method and system of multimedia service performance monitoring is provided. The method comprises the following steps: (a) a reference point acquires and stores the association relationship between multimedia packet identification number and the corresponding multimedia information; (b) a sample point orders the received packets according to the multimedia packet identification numbers, detects the integrality of the packets, and feeds the identification numbers of the lost multimedia packets back to the reference point if there are lost packets; (c) the reference point obtains the corresponding multimedia information according to the identification numbers of the lost multimedia packets returned by the sample point and the stored association relationship between the multimedia packet identification number and the corresponding multimedia information, and then evaluates the multimedia service quality of the sample point.
摘要:
Methods for creating a transient nanoscale opening in a cell membrane and methods for transporting a desired species through the nanoscale opening are provided. A nano-sized needle-like tip can be used to mechanically slice the cell membrane to create a transient, localized nanoscale slit. The nanoscale slit may be used for transferring exogenous molecules into a living cell
摘要:
Methods and systems for enhancement of device accessibility are described. In an example, an operating system configured to be executed on a device, may be configured to support a plurality of software applications and to support a plurality of modes of operation of the device. A given software application may include a user-interface comprising a user-interface item having a text in a first language. The operating system may be configured to receive a selection of the user-interface item of the given software application. Based on the operating system being in an accessibility mode common to the plurality of software applications, the operating system may be configured to determine a translation of the text into a second language; and a voice output corresponding to a spoken utterance of the translation of the text. The operating system further may be configured to provide, by the device, the voice output.
摘要:
A method for accelerating network accessing of a terminal in a wireless communication system, comprises: a wireless terminal receiving system parameter information, and after obtaining system information of a base station identifier (BS ID) and a network access provider identifier (NAP ID), immediately judging validity of the NAP ID, or validity of both the NAP ID and the BS ID; if a result of the judgment is “valid”, the terminal proceeding to a subsequent procedure of the network discovery and selection according to information stored in the terminal, otherwise, carrying out a new procedure of network discovery and selection. The method avoids continuing to perform processes such as message receiving and decoding in the case that a NAP ID or a BS ID is invalid according to a procedure in the current protocol, thereby increasing the speed of network accessing of a terminal.
