Context.— Preanalytic errors, including specimen labeling errors and specimen loss, occur frequently during specimen collection, transit, and accessioning. Radio-frequency identification tags can decrease specimen identification and tracking errors through continuous and automated tracking of specimens. Objective.— To implement a specimen tracking infrastructure to reduce preanalytic errors (specimen mislabeling or loss) between specimen collection and laboratory accessioning. Specific goals were to decrease preanalytic errors by at least 70% and to simultaneously decrease employee effort dedicated to resolving preanalytic errors or investigating lost specimens. Design.— A radio-frequency identification specimen-tracking system was developed. Major features included integral radio-frequency identification labels (radio-frequency identification tags and traditional bar codes in a single printed label) printed by point-of-care printers in collection suites; dispersed radio-frequency identification readers at major transit points; and systems integration of the electronic health record, laboratory information system, and radio-frequency identification tracking system to allow for computerized physician order entry driven label generation, specimen transit time tracking, interval-based alarms, and automated accessioning. Results.— In the 6-month postimplementation period, 6 mislabeling events occurred in collection areas using the radio-frequency identification system, compared with 24 events in the 6-month preimplementation period (75% decrease; P = .001). In addition, the system led to the timely recovery of 3 lost specimens. Labeling expenses were decreased substantially in the transition from high-frequency to ultrahigh frequency radio-frequency identification tags. Conclusions.— Radio-frequency identification specimen tracking prevented several potential specimen-loss events, decreased specimen recovery time, and decreased specimen labeling errors. Increases in labeling/tracking expenses for the system were more than offset by time savings and loss avoidance through error mitigation.

ABSTRAK Proses pengangkutan dan pencampuran batubara di PT Adaro Indonesia terbilang cukup unik, menggunakan sistem ‘blending berjalan”, proses pencampuran dilakukan dengan mengatur waktu kedatangan alat pengangkut batubara di terminal fasiltas pemrosesan batubara dan pengisian tongkang agar tiba sesuai dengan waktu yang direncanakan. Untuk menunjang proses optimasi agar menghasilkan kualitas pencampuran yang on spec dan on time dibutuhkan sistem monitoring material, method dan machine yang mumpuni. Teknologi Radio Frequency Identification (RFID) dipilih karena mampu menghasilkan komunikasi data yang cepat. Komponen utama RFID adalah alat pembaca (reader) dan alat penanda (tagger). Alat pembaca dirakit secara elektronik dan beroperasi dengan memanfaatkan sumber energi panas matahari konversi dari solar cell dan ditempatkan di setiap titik strategis di jalur pengangkutan. Alat tagger ditempatkan pada semua alat pengangkut batubara (trailer). Sistem software dan database dibuat secara lokal dan terintegrasi ke pusat database yang terhubung melalui topologi jaringan. Semua transaksi kegiatan pengangkutan mulai dari alat angkut dalam  posisi kosong, pengisian, penimbangan sampai penumpahan atau penumpukan diproses secara online dan real time. Sistem ini juga diintegrasikan dengan aplikasi tracking monitoring yang dibuat dan dikembangkan untuk pemantauan data secara real time oleh semua pihak yang terlibat dalam rantai pasok operasional pengangkutan dan pencampuran batubara.Implementasi integrasi teknologi yang disusun berdasarkan analisa kebutuhan bisnis proses ini memberikan dampak langsung dan tidak langsung. Secara biaya pengadaan dan perawatan, tools ini lebih murah dari produk pasaran yang ditawarkan. Dari segi kualitas menghasilkan peningkatan presisi pencampuran. Sisi operasional juga memberikan penghematan dari proses kerja yang efisien dengan peningkatan produktivitas alat angkut. Tindakan perbaikan yang berkelanjutan dan tepat sasaran dari aktivitas pengangkutan dan pencampuran juga dapat dilakukan karena data evaluasi yang dihasilkan dari integrasi teknologi ini valid dan dapat diandalkan. Kata Kunci : RFID, Coal Hauling, Coal Blending, Hauling Tracking System  ABSTRACT Coal hauling and mixing in PT Adaro Indonesia is fairly unique, using an “on the way mixing” system, the mixing process is operated by setting the arrival time of the coal truck at coal processing and barge loading terminal facility so that truck arrived according to planned time. In order to support the optimization process to produce optimum quality mixing that is on spec and on time, require capable monitoring system of material, method and machine. Radio Frequency Identification (RFID) technology was chosen because it is able to produce fast data communications. The main components of RFID are reader and tagger. The reader is electronically assembled and operated by using thermal energy conversion from solar cell which placed at each strategic point along hauling road. The tagger is placed on every coal truck (trailer). The software and database system is created locally and integrated into central database that connected through network topology. All transaction from hauling activity starting from the trucks at empty position, loading, passing, weighing until dumping are processed online and real time. This system also integrated with tracking monitoring application that is established and developed for real time monitoring by all parties involved in coal supply chain. The implementation of this technology integration that based on business needs analysis has direct and indirect impact. In terms of investment and maintenance costs, these tools are cheaper than commonly product offered in industrial market. From quality aspect results, it gives enhancement of mixing precision. The operational side also provides saving from efficient working process by increasing truck productivity. Continuous and accurate corrective action from coal hauling and blending operation can also be done because data evaluation that generated from this integrated technology are valid and reliable. Keyword: RFID, Coal Hauling, Coal Blending, Hauling Tracking System

Individual data are valuable for assessing the health, welfare and performance of broilers. In particular, data on the first few days of life are needed to study the predictive value of traits recorded early in life for later life performance. However, broilers are generally kept in groups, which hampers individual identification and monitoring of animals. Sensor technologies may aid in identifying and monitoring individual animals. In this study, a passive radio frequency identification (RFID) system was implemented to record broiler activity, in combination with traditional video recordings. The two main objectives were (1) to validate the output of the RFID system by comparing it to the recorded locations on video, and (2) to assess whether the number of antennas visited per unit time could serve as a measure of activity, by comparing it to the distance recorded on video and to the distance moved as recorded using a validated ultra-wideband (UWB) tracking system. The locations recorded by the RFID system exactly matched the video in 62.5% of the cases, and in 99.2% of the cases when allowing for a deviation of one antenna grid cell. There were moderately strong Spearman rank correlations between the distance recorded with the RFID system and the distance recorded from video (rs = 0.82) and between UWB and RFID (rs = 0.70) in approximately one-hour recordings, indicating that the RFID system can adequately track relative individual broiler activity, i.e., the activity level of a broiler in comparison to its group members. As the RFID tags are small and lightweight, the RFID system is well suited for monitoring the individual activity of group-housed broilers throughout life.

Frequency Identification

Radio frequency identification (RFID) in the form of tags or transponders is a means of auto-ID that can be used for tracking and monitoring objects, both living and non-living. One of the first applications of RFID was in the 1940s within the US Defense Force (Hodges & McFarlane, 2004, p. 59). Transponders were used to differentiate between friendly and enemy aircraft (Ollivier, 1995, p. 234; Scharfeld (1998, p. 9). Since that time, transponders continued mainly to be used by the aerospace industry (or in other niche applications) until the late 1980s when the Dutch government voiced their requirement for a livestock tracking system. The commercial direction of RFID changed at this time and the uses for RFID grew manifold as manufacturers realized the enormous potential of the technology.

Proportional Relationship

Radio Frequency Identification (RFID), as the name suggests, is technology that makes use of radio frequency electromagnetic wave to automatically identify objects. In spite of its broad applications, a RFID system might inherently produce some false and duplicate readings. Such reading data would affect the accuracy of the RFID system and might result in an unreliable performance or even complete unavailability of the system. In this paper, a reading rate-based algorithm is proposed to efficiently clean RFID data for a local business in product tracking. The method takes advantage of the proportional relationship between reading rate of a RFID tag and its distance to the reader to filter among raw data sets. Using the proposed reading rate-based algorithm, the reading accuracy of the RFID system in the local business is greatly improved.

Indoor Tracking

Radio frequency identification (RFID) can effectively get the accurate location information for indoor tracking system. The readers cant be placed at any position in the practical system. the reader would be more intensive at some places, where will obtain measurements from several readers, while the reader will be placed less at others place, where less or no measurements may be get when the target gets in this area. Therefore the target trajectory should be estimated by fusion filtering methods with variable sensors. The experiments show that the fusion UKF with variable sensors can overcome RFID nonlinear is smooth without abrupt change, even when the number of sensors has undergone great changes.
