A power-on circuit of a computer includes a heat sink, an SIO chip, a connector, a first electric switch, a second electric switch, and a third electric switch. When the heat sink is installed properly, the heat sink is grounded, and the first electric switch is turned off. After a power-on button is pressed down, a power supply on pin of the SIO chip sends a low level signal to turn off the second electric switch, the third electric switch is turned on, a power supply on pin of the connector is at a low level, and the computer is powered on. When the heat sink is installed improperly, the heat sink is not grounded, the first electric switch is turned on, the third electric switch is turned off, the power supply on pin of the connector is at a high level, and the computer cannot be powered on.

An implementation method and system for accelerating the paging access of a mobile station in broadband wireless system are disclosed, and this system comprises base stations, mobile stations, an anchor access network gateway, an authenticator and a paging controller. The implementation method includes: (a) the anchor access network gateway sends to the base station a Paging Announce message including at least mobile station identifier and the authenticator identifier of the mobile station; (b) the base station keeps the corresponding relationship of the authenticator identifier and the mobile station, and sends a MOS-PAG-ADV message to the mobile station; (c) after the base station receives the RNG-REQ message from the mobile station, it interacts with the authenticator using the authenticator identifier to obtain the authentication key and perform the authentication; and acquire the information of mobile station from the paging controller; (d) before or after the base station requests the anchor access network gateway to establish a data channel, it sends a RNG-RES message to the mobile station; (e) after the anchor access network gateway receives the Data Channel Establishment Acknowledgement message, it informs the paging controller to delete the mobile station information thereon. The present invention can accelerate the process of paging access of the mobile station.

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.

Ferroelectric rare-earth manganese-titanium oxides and methods of their manufacture. The ferroelectric materials can provide nonvolatile data storage in rapid access memory devices.
摘要:
Novel metal oxide compositions are disclosed. These ferromagnetic or ferrimagnetic compositions have resitivities that vary between those of semiconducting and insulating materials, and they further exhibit Curie temperatures greater than room temperature (i.e., greater than 300 K). They are perovskite structures with the general chemical formulas (A1-xMx)BO3, (A1-xMx)(B′B″)O3 or A(B1-xMx)O3, where A can be a 1+, 2+ and 3+ charged ion; B can be a 5+, 4+, 3+ charged ion; B′ and B″ can be 2+, 3+, 4+, 5+ and 6+ charged ion. M is a magnetic ion dopant. X-ray diffraction patterns are presented for exemplary compositions.

An electrical connector comprises an insulating housing (1) defining a receiving cavity opening (101) through a front face thereof for receiving a mating connector, a plurality of conductive terminals (2) comprising an elastic contacting portion (22) slantwise extending into the receiving cavity and a discrete limiting member (4) being inserted into the cavity through a inserting opening (15) and positioned under the contacting portion so as to prevent the contacting portions from over moving when an un-mating connector is inserted into the receiving cavity.

A method and system for Extensible Markup Language (XML) schema validation, includes: loading an XML document into a runtime validation engine, where the runtime validation engine includes an XML schema validation parser; loading an annotated automaton encoding (AAE) for an XML schema definition into the XML schema validation parser; and validating the XML document against the XML schema definition by the XML schema validation parser utilizing the annotated automaton encoding. Each XML schema definition is compiled once into the AAE format, rather than being compiled each time an XML document is validated, and thus significant time is saved. The code for the runtime validation engine is fixed and does not vary depending on the XML schema definition, rather than varying for each XML schema definition, and thus space overhead is minimized. Flexibility in the validation process is provided without compromising performance.
摘要:
An electrical connector (100) for permitting insertion of a full sized plug (200) and for preventing insertion of a smaller sized plug (300) includes an insulative housing (1) defining a receiving cavity (101) through a front face (10) thereof and a plurality of receiving grooves (12) extending in a mating direction of the plug at one inner side (11) of the receiving cavity and a plurality of terminals (2). Each terminal defines a fixing portion (21) received and retained in the receiving groove, a contacting portion (22) extending into the receiving cavity from a front end of the fixing portion and a soldering portion (23) extending from a rear end of the fixing portion. The electrical connector further defines at least one protrusion (121) discrete with the terminal, the at least one protrusion is in front of and aligns with one contacting portion of the outmost terminals.
