The RFID reader module is connected to a first antenna. The mobile vehicle includes a second antenna and a third antenna. The second antenna is connected to the third antenna via a coaxial cable, and the mobile vehicle carries multiple objects that are equipped with RFID tags. As the mobile vehicle moves pass the RFID reader module, a first radio frequency signal is transmitted to the mobile vehicle from the RFID reader module via the first antenna. The mobile vehicle then receives the first radio frequency signal with the second antenna and transmits the first radio frequency signal to the third antenna via the coaxial cable. The first radio frequency signal is transmitted to the RFID tags on the objects from the mobile vehicle via the third antenna.Type: ApplicationFiled: March 28, 2016Publication date: September 28, 2017Inventors: Tai-Hwa LIU, Yi-Chun SUNG

Patent number: 9010637Abstract: A wireless radio frequency identification receiving facility having antenna net includes a receiving apparatus with receiving spaces for receiving objects, a leaking-waved antenna net unit, and a first antenna. The leaking-waved antenna net unit includes an inner main antenna and extension antennas extended to the regions adjacent to the receiving spaces. The first antenna receives the detecting signal from a reader unit and generates a current. The EM wave is generated while the current flows through the leaking-waved antenna net unit, and is transmitted along extension antennas. The radio frequency identification electronic tags on the objects are triggered by the electromagnetic field built up by the EM wave, and information of all objects in the receiving apparatus is read at one time, so that the checking time is greatly reduced and the possibility of lost and position mistake of object can be excluded.Type: GrantFiled: February 21, 2013Date of Patent: April 21, 2015Inventors: Tai-Hwa Liu, Yi-Chun Sung

Publication number: 20150097655Abstract: A radio frequency identification (RFID) display device includes a microprocessor, a first RFID, a second RFID, a sensing module and a passive display unit. The first RFID stores a first RFID data and receives electromagnetic wave emitted from a reader for supply power. The second RFID stores a second RFID data. The first RFID data and the second RFID data are transferred to the microprocessor when the electromagnetic wave is received. The sensing module senses an external environment and generates an environmental sensing signal transferred to the microprocessor. The microprocessor generates a display driving signal to drive the passive display unit based on the received data so as to display the RFID data onto the passive display unit. The microprocessor further adjusts the brightness and the contrast of the passive display unit to achieve better display effect, thereby effectively saving the time of stock take.Type: ApplicationFiled: October 9, 2013Publication date: April 9, 2015Inventors: Tai-Hwa Liu, Yi-Chun Sung

Patent number: 8844814Abstract: A radio frequency identification automatic detecting system with an antenna net includes a radio frequency identification module, an enhancing surface wave-guide coaxial cable structure including a coaxial cable having at least one aperture region without an outer conducting layer, a receiving apparatus having a plurality of receiving spaces and a plurality of extension wires disposed adjacent to the receiving spaces and coupled or connected to the outer conducting layer of the coaxial cable. The electromagnetic field is formed in nearby regions adjacent to the receiving spaces because the electromagnetic wave caused by the current generated from the radio frequency identification module is transmitted by the outer conducting layer and extension wires. The radio frequency identification electronic tag on the object is triggered automatically when the object is moved toward or moved out from the respective receiving space such that the automatic detecting effect is achieved.Type: GrantFiled: December 10, 2012Date of Patent: September 30, 2014Inventors: Tai-Hwa Liu, Yi-Chun Sung

Patent number: 8289168Abstract: An RFID anti-theft tag structure is disclosed. The RFID anti-theft tag structure includes a first protective layer, a paper sheltering layer, a permanent-magnetic alloy film, an RFIC, a sticky film, at least one alloy sheet, and a second protective layer sequentially disposed one on another from bottom to upper side. The alloy sheet can be repetitively magnetized and demagnetized. The permanent-magnetic alloy film and the alloy sheet are thus combined for cooperatively achieving the anti-theft function. The permanent-magnetic alloy film is divided into two independent portions, which are electrically coupled to the RFIC for serving as an antenna of the RFIC so as to achieve the RFID function. In such a way, the RFID anti-theft tag structure of the present invention integrally attains the anti-theft tag function and the RFID function, saves production cost and improves the convenience of use.Type: GrantFiled: December 18, 2009Date of Patent: October 16, 2012Inventors: Tai-Hua Liu, Yi-Chun Sung
