|20140223518||AUTHENTICATION AND AUTHORIZATION METHOD AND SYSTEM - An authentication and authorization method and system are provided. The method includes: receiving an authentication request transmitted from a first device; transmitting the authentication request to an authentication and authorization server subsystem; authenticating the authentication request and generating authentication information; generating an authorization request used to request a second device for authorization according to the authentication information; and authenticating the authorization request, generating an authorization information and transmitting the authorization information to the first device through an authentication and authorization client subsystem so that the first device communicates with the second device directly according to the authorization information.||08-07-2014|
|20140137164||IN-FLIGHT ENTERTAINMENT SYSTEMS AND METHODS FOR PROVIDING DIGITAL CONTENT IN AN AERIAL VEHICLE - An In-Flight Entertainment system is provided with a server unit and a display unit. The server unit is configured to maintain digital content. The display unit is configured to connect to the server unit through a wired network for receiving and presenting the digital content. The display unit further includes a wireless module for wirelessly transmitting the digital content received from the server unit to be presented by a first portable device.||05-15-2014|
|20120315034||Detector And Method Thereof - This invention provides a detecting device and a method for a passive optical network (PON), which includes: a laser device; a detector coupled to the laser device and generating an output signal at one of a first level when the laser device emits light and a second level when the laser device does not emit light; and a processor repeatedly detecting the output signal in a fixed period, and simultaneously counting a total number of changes that the output signal changes from the first level to the second level and the output signal changes from the second level to the first level so as to detect whether a light leakage occurs in the PON.||12-13-2012|
|20090262025||ANTENNA AND ANTENNA SET - An antenna and an antenna set are provided. The antenna is composed of a horseshoe sheet member and two rectangular sheet members. The horseshoe sheet member and the two rectangular sheet members are all made of a metal material. The antenna is made of a metal material, such as tinplate, and the antenna is adapted for receiving or emitting wireless signals of vertical polarization and horizontal polarization. The antenna set includes three antennae as above disposed on a substrate. The antenna set is adapted for polarization diversity, pattern diversity, and space diversity. Comparing with the conventional antenna and antenna set, the antenna and the antenna set according to the present invention have lower costs and lower heights, and can be designed as embedded antennae or hidden antennae.||10-22-2009|
|20090079659||MULTI-MODE RESONANT WIDEBAND ANTENNA - A wireless transmit/receive unit for transmitting and receiving an electromagnetic wave and a method for the same are provided. The wireless transmit/receive unit includes a radiating element and a feeding line. The radiating element is a metal piece having a first edge with a first length, a second edge with a second length, and a plurality of cutouts. The first and second edges are separated from each other and the first length is longer than the second length. Further, the cutouts are formed on the metal piece respectively, which makes the metal piece have a zigzag shape. In addition, the feeding line is electrically connected to the second edge.||03-26-2009|
|20090079657||PRINTED MONOPOLE SMART ANTENNA FOR WLAN AP/ROUTER - A printed monopole smart antenna is provided. The smart antenna includes a monopole antenna having a plane for receiving and transmitting a signal, two conductors for directing and/or reflecting the signal to the monopole antenna respectively, and a circuit device electrically connected between the first and second conductors, for selectively switching the first and second conductors to determine an operation mode of the smart antenna. The smart antenna further has at least a groove in the ground for concentrating the current distribution and solving the influence of the antenna gain to the ground size. The sequence of the antenna pattern of the smart antenna is randomly arranged, depending on user's situation. When a plurality of printed monopole smart antennas are disposed on different directions of the WLAN AP/router, the omnidirectional radiation pattern will be obtained and the antenna gain will be increased.||03-26-2009|
