Patent number: 8290424Abstract: An antenna system and a corresponding method for satellite lock-on applied to vehicles automatically lock on at least one satellite in the space by means of a lock-on signal. The technique features on a scan driving signal that initiates a space scan of the antenna system so as to obtain a scan data. According to peak values of the scan data, coordinates of a plurality of satellites in the space are realized and individually recorded. Then, after receiving a lock-on signal, the satellite coordinate of the satellite to be locked is retrieved so as to drive the antenna to point at the satellite to be locked.Type: GrantFiled: March 11, 2009Date of Patent: October 16, 2012Assignee: Azure Shine International Inc.Inventors: Wen-Chao Shen, Wen-Yen Shen, Shun-Ching Chen

Publication number: 20100111507Abstract: A mobile digital signal transceiving device comprises a multimedia interface, a processing unit and a radio frequency (RF) signal transmitter. The multimedia interface reads at least one multimedia data stored in at least one multimedia memory device. The processing unit transfers the multimedia data into a terrestrial broadcast data in a digital video broadcasting-terrestrial (DVB-T) data format, and modulates the terrestrial broadcast data in order to generate an RF signal. The RF signal transmitter transmits the RF signal so that the RF signal may be received by at least one mobile multimedia device.Type: ApplicationFiled: July 28, 2009Publication date: May 6, 2010Applicant: AZURE SHINE INTERNATIONAL INC.Inventors: WEN-CHAO SHEN, WEN-YEN SHEN, SHUN-CHING CHEN

Publication number: 20100058399Abstract: A method for satellite lock-on in an antenna system by channel selection is initiated by receiving a channel selection signal. The channel selection signal is flagged to retrieve satellite parameters corresponding to the selected channel from a pre-stored satellite channel table which provides a correlation among the channels, the bands and the satellite coordinates. Then, according to the retrieved satellite parameters, an antenna control signal and thus a drive signal are generated orderly to drive the antenna to direct at the satellite responsible to the selected channel.Type: ApplicationFiled: May 21, 2009Publication date: March 4, 2010Applicant: AZURE SHINE INTERNATIONAL INC.Inventors: Wen-Chao Shen, Wen-Yen Shen, Shun-Ching Chen

Publication number: 20040028374Abstract: The present invention relates to a multi-AV control device in an automobile which consists of a multi-AV device and a plurality of displays. The multi-AV device is connected with a plurality of AV-signal input sources and the displays. The multi-AV device is controllable by press buttons or a remote control of every display to choose different AV-signal source while the chosen AV-signal source is shown on corresponding display. The control command is given by the displays to the multi-AV device, whereupon the multi-AV device transmits signals back to the display and which are shown on the corresponding display so that this two-way communication achieves control and display effect. Accordingly, the present invention can achieve a more convenient and accurate operation in choosing desired AV-signals.Type: ApplicationFiled: August 7, 2002Publication date: February 12, 2004Inventors: Wen-yen Shen, Shun-Ching Chen
