Patent number: 8390429Abstract: A mobile RFID (Radio Frequency Identification) system and method are provided to monitor multiple control zones of the system simultaneously through a mobile outpost monitor. The control zones included in the system are connected with each other through a data exchange interface. Each of the control zones includes a link interface connecting with a gateway of at least one RFID tracking module. The gateway connects with at least one RFID reader and a signal transmitter to receive tag information of RFID tags within the control zone, and transmits the tag information through the signal transmitter. When the mobile outpost monitor moves from one control zone to another, the mobile outpost monitor may switch to link with the signal transmitter of the gateway in the current control zone. Through the data exchange interface, the mobile outpost monitor is able to obtain the monitoring information of another control zones.Type: GrantFiled: January 23, 2009Date of Patent: March 5, 2013Assignee: Getac Technology CorporationInventors: Jun-Ting Shiau, Ta-Yung Lee, Jen-Hao Hsu, Chia-Chin Yu

Patent number: 8339243Abstract: A positioning system and method are provided to use multiple RFID readers to position a target object with an active RFID tag equipped thereon. The system and method defines a geometric center of the locations of the RFID readers as a first coordinate. When the RFID readers continuously receive RF signals of the active RFID tag, a corresponding signal intensity of each of the RF signals is calculated and compared to obtain an approaching vector corresponding to the location of the RFID reader with the greatest signal intensity of the RF signal. A positioned location of the target object is then approached from the first coordinate to a second coordinate according to the approaching vector. The first coordinate and the positioned location of the target object will be reset as the second coordinate. The reset first coordinate is output as the latest positioned location of the target object.Type: GrantFiled: December 31, 2008Date of Patent: December 25, 2012Assignee: Mitac Technology Corp.Inventors: Jun-Ting Shiau, Jen-Hao Hsu, Chia-Chin Yu

Patent number: 8174385Abstract: A radio frequency identification (RFID) reader includes a plurality of signal antennas, which are respectively arranged in directions that are not parallel to and co-linear with each other. Each of the signal antennas has a predetermined antenna field pattern and operates with a predetermined carrier wave frequency. A wireless receiver is connected to the signal antennas. A signal conversion unit is connected to the wireless receiver. A frequency generator generates the carrier wave frequency to the signal antenna. A microprocessor is connected to the signal conversion unit and the frequency generator.Type: GrantFiled: September 29, 2008Date of Patent: May 8, 2012Assignee: Mitac Technology Corp.Inventors: Shin-Yao Perng, Ta-Yung Lee, Chia-Chin Yu, Jun-Ting Shiau

Publication number: 20100141385Abstract: A handheld electronic device and mobile RFID (Radio Frequency Identification) reader equipped thereon allow a user to move to wherever necessary and sense RFID tag data of a target object. The mobile RFID reader includes a microprocessor, a memory unit connected to the microprocessor, a reader positioning unit, a RFID transceiver, a temporary data storage and a network interface. The reader positioning unit positions the location of the RFID reader to obtain reader location information of the RFID reader, and then the RFID transceiver receives a tag signal with tag ID (Identification) data from RFID tag. The reader location information and the tag ID data of the RFID tag are able to be stored optionally in the temporary data storage, and will be uploaded to a backend network sever whenever the RFID reader is connected to the backend network sever through its network interface.Type: ApplicationFiled: December 9, 2008Publication date: June 10, 2010Applicant: MITAC TECHNOLOGY CORP.Inventors: JUN-TING SHIAU, TA-YUNG LEE, JEN-HAO HSU, CHIA-CHIN YU

Publication number: 20100079337Abstract: A system and method is provided to track positions of a portable electronic device. Different communication modules capable of retrieving position signals are enabled selectively according to the status/type of position signals of the portable electronic device. All of the different communication modules are enabled when the portable electronic device locates around a boundary between different regions that require different communication modules to obtain geography information. Therefore, by means of seamless transferring operation between different communication modules, a remote manager may be able to continuously monitor the positions of the portable electronic device.Type: ApplicationFiled: September 30, 2008Publication date: April 1, 2010Applicant: MITAC TECHNOLOGY CORP.Inventors: Jun-Ting Shiau, Ta-Yung Lee, Jen-Hao Hsu, Chia-Chin Yu
