Patent number: 8736440Abstract: 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.Type: GrantFiled: October 31, 2011Date of Patent: May 27, 2014Assignee: Hana Micron America, Inc.Inventors: Sung Bok Kwak, Yong Hyun Lee, Toan Tran, Sungryol Jin, Songtao Jin

Patent number: 8671772Abstract: 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.Type: GrantFiled: September 22, 2011Date of Patent: March 18, 2014Assignee: Hana Micron America, Inc.Inventors: Sung Ryol Jin, Yong Hyun Lee
