  • Publication number: 20130284858
    Abstract: A three-dimensional cellular light structure formed of continuous wire groups. For example, six orientational helical wire groups are intercrossed in a three-dimensional space and form a uniform pattern. In a manufacturing method, a frame assembly of rectangular frames and connection support bars is used. The method includes arranging and fixing first axis wires on the frames, connecting the frames by connection support bars, and assembling second axis wires to make a three-dimensional cellular light structure. The intersection points of the wires may be bonded. It can be a fiber-reinforced composite material by filling at least part of an internal empty space of the structure.

  • Patent number: 8418730
    Abstract: Disclosed herein is a three-dimensional cellular light structure formed of continuous wire groups. In the cellular light structure, six orientational helical wire groups are intercrossed each other at 60 degrees or 120 degrees of angles in a three-dimensional space to thereby form a uniform pattern and having a good mechanical property such as strength, rigidity or the like. A method of mass-producing the structure in a cost-effective manner is also disclosed. The three-dimensional cellular light structure has a similar form to the Kagome truss. According to the manufacturing method of the three-dimensional cellular light structure of the present invention, a frame assembly consisting of rectangular frames and connection support bars is used, when the 1st, 2nd, 3rd, 4th, 5th and 6th-axis helical wires are assembled.

  • Publication number: 20130074607
    Abstract: A novel RFID tag-bending test apparatus and a related method of using the novel RFID tag-bending test apparatus are disclosed. In one embodiment of the invention, the novel RFID tag-bending test apparatus can place a plurality of RFID tags in corresponding tag holding clips on the novel RFID tag-bending test apparatus to execute a bending test sequence along a particular bending axis for each RFID tag. The bending test sequence can assist identifying defective RFID tags which cannot overcome external bending pressures asserted by the novel RFID tag-bending test apparatus. By excluding these defective RFID tags from a commercial shipment of RFID tags to customers, a manufacturer of RFID tags may be able to reduce a rate of premature RFID tag failures due to external bending pressures in real-life applications of RFID tags, thereby achieving a higher quality assurance and reliability of RFID tags.

  • Publication number: 20130043983
    Abstract: An apparatus and a method for translating, transcribing, and/or converting a printed label on a surface of an RFID tag into electronic data, which are writable to a non-volatile storage inside the RFID tag, are disclosed. In one example, the apparatus comprises an image reader for scanning a printed label on the surface of an RFID tag, a UHF antenna module, a UHF tag access module for reading from or writing into the RFID tag, and a computer interface to display various parameters and control the apparatus. A tag-holding plate containing batches of RFID tags can be brought to an access range of the image reader using a conveyor belt or another moving mechanism. Once positioned within the access range, the apparatus can read and translate a printed label on a RFID tag and write the converted electronic data into a non-volatile storage inside the RFID tag.

  • Publication number: 20120326874
    Abstract: An early alert system and a method for livestock disease detection are disclosed. An activity measurement zone (AMZ) is defined near an incentive device (e.g. food or water dispensing system) with an RFID tag reader and/or an RFID antenna. An animal's access into the AMZ is tracked and counted with an RFID tag attached to the animal. If the animals' activity relative to the AMZ drops to an alarmingly low level (e.g. dropping below an alert trigger point) over time, then a user of the alert system is informed of a potential health problem of the animal and may also be encouraged to inspect the animal in person for further determination of its current health and potential medical issues. The early alert system may be powered by hybrid alternative energy sources for rural or remote areas, which may have inconvenient or expensive access to conventional electrical power lines.
