Patent number: 8947209Abstract: A radio frequency identification (RFID) system employs multiple band transmission to prevent signal collision. The system includes a plurality of RFID tag groups and at least one RFID reader. Each RFID tag group includes at least one RFID tag. The RFID tags of the same RFID tag group are operated for radio frequency transmission in the same transmission frequency band, and those of different RFID tag groups are operated for radio frequency transmission in different transmission frequency bands. When the RFID reader simultaneously receives radio frequency signals issued from RFID tags of different RFID tag groups, since they are transmitted in different transmission frequency bands, signal collision among the RFID tags of the RFID tag groups can be avoided.Type: GrantFiled: October 29, 2008Date of Patent: February 3, 2015Assignee: Getac Technology CorporationInventors: Yuan-Ning Hsieh, Ta-Yung Lee, Shin-Yao Perng

Patent number: 8305195Abstract: A radio frequency identification (RFID) communication system and method is provided to resolve the power-consuming problems of an active RFID tag while operating at a receiving mode in a long duration. A designated channel is established between the reader and the RFID tag, and also the reader sends a designated message so that the actuated active RFID tag can receive the designated messages and dynamically enter into a receiving mode. Therefore, normal communications may be conducted between the reader and the RFID and the usage period or technical performance can be improved as well.Type: GrantFiled: September 30, 2008Date of Patent: November 6, 2012Assignee: Getac Technology Corp.Inventors: Shin-Yao Perng, Ta-Yung Lee, Chih-Wen Cheng, Yuan-Ning Hsieh

Patent number: 8275858Abstract: A method is provided to update firmware of a radio frequency identification (RFID) reader through a network system, wherein a management host issues an update message to a gateway through the network system, and then depending upon the location where reader firmware update data is stored, either the management host transmits the reader firmware update data through the gateway to each designated RFID reader, or the gateway directly transmits the reader firmware update data to each of the designated RFID readers. A microprocessor of the RFID reader stores the received reader firmware update data to a firmware data storage section of a memory unit thereof.Type: GrantFiled: September 18, 2008Date of Patent: September 25, 2012Assignee: Mitac Technology Corp.Inventors: Shin-Yao Perng, Chih-Wen Cheng

Patent number: 8135984Abstract: A method for reconstructing a RAID system is disclosed. Plural disks are corresponded to plural pieces of unique recognition data, where each disk corresponds to one of the recognition data. A disk profile is generated according to the recognition data using a RAID system, wherein the disk profile comprises a logic section combined with the disks and the logic section respectively corresponds to the recognition data of different disks based on stored data in different disks. The disks are mounted to a computer device providing the RAID system. The mounted disks are mapped to correct disk mount addresses according to the disk profile to reconstruct the stored data of the disks in the computer device.Type: GrantFiled: November 6, 2008Date of Patent: March 13, 2012Assignee: Mitac Technology Corp.Inventor: Shin-Yao Perng

Publication number: 20100164687Abstract: A method for identifying an RFID (Radio Frequency IDentification) reader is provided. A first transmission path is defined between a first RFID reader and a host apparatus in a RFID system. A second transmission path is defined between the host apparatus and a second RFID reader adjacent to the first RFID reader. When the host apparatus is identifying the first RFID reader, the first RFID reader sends first identification data of the first RFID reader through the first transmission path to the host apparatus. The first RFID reader also sends first-resent identification data of the first RFID reader through the second transmission path to the host apparatus. The host apparatus identifies the first RFID reader by comparing the first identification data and the first-resent identification data transmitted through the first transmission path and the second transmission path respectively, thereby double confirming the identification data of the first RFID reader.Type: ApplicationFiled: December 30, 2008Publication date: July 1, 2010Applicant: MITAC TECHNOLOGY CORP.Inventors: Shin-Yao Perng, Ta-Yung Lee, Yuan-Ning Hsieh
