20100008039 | PORTABLE ELECTRONIC DEVICE - The invention discloses a portable electronic device comprising a casing, a first support and a second support. The casing comprises a bottom and a recess formed on the bottom. The recess comprises a first side-portion and a second side-portion opposite to the first side-portion. The first support thereon has a first end and a second end, and the second support thereon has a third end and a fourth end. The first end of the first support is slidably connected between the first and second side-portions. The third end of the second support is pivotally connected to the second end of the first support. The fourth end of the second support is pivotally connected between the first and second side-portions. When the first end of the first support slides along the first and second side-portions, the first support will drive the second support to rotate with respect to the casing. | 01-14-2010 |

20120175631 | ENHANCEMENT MODE GaN HEMT DEVICE WITH GATE SPACER AND METHOD FOR FABRICATING THE SAME - Enhancement-mode GaN devices having a gate spacer, a gate metal material and a gate compound that are self-aligned, and a methods of forming the same. The materials are patterned and etched using a single photo mask, which reduces manufacturing costs. An interface of the gate spacer and the gate compound has lower leakage than the interface of a dielectric film and the gate compound, thereby reducing gate leakage. In addition, an ohmic contact metal layer is used as a field plate to relieve the electric field at a doped III-V gate compound corner towards the drain contact, which leads to lower gate leakage current and improved gate reliability. | 07-12-2012 |

20090327697 | NETWORK SECURITY PROCESSING METHOD AND SYSTEM FOR SELECTING ONE OF SOFTWARE AND HARDWARE CRYPTOGRAPHIC MODULES BY MEANS OF MULTIMEDIA SESSION INFORMATION - In a network security processing method and system for selecting one of software and hardware cryptographic modules by means of multimedia session information, the method includes the following steps: subjecting a plurality of packets of a multimedia session to signaling processing so as to obtain multimedia session information contained in the multimedia session, subjecting the multimedia session to a key authentication negotiation and according to the multimedia session information, making a determination to activate one of the software cryptographic module and the hardware cryptographic module. If the hardware cryptographic module is activated, the hardware cryptographic module performs network security processing of the packets of the multimedia session. If the software cryptographic module is activated, the software cryptographic module performs the network security processing of the packets of the multimedia session. | 12-31-2009 |
20100153726 | AUTHENTICATION METHOD, SYSTEM, AND APPARATUS THEREOF FOR INTER-DOMAIN INFORMATION COMMUNICATION - The present invention provides an authentication method for inter-domain information communication applied to first and second domains. The method instructs a first electronic device belonging to the first domain to request, through an intermediary node device simultaneously registered in the first and second domains, to obtain a first key from a second key distribution center in the second domain for transmission to a second electronic device in the second domain, and instructs the second electronic device to request, through the intermediary node device, to obtain a second key from a first key distribution center in the first domain for transmission to the first electronic device. Therefore, the first and second electronic devices are instructed to generate a shared third key using the first and second keys to perform secure information communication authentication. | 06-17-2010 |
