A Technology Aid to Help People with Blindness and Moderate Intellectual Disability Retrieve Common Objects from Storage Units: A Proof-of-Concept Study.

People with blindness and intellectual disability can have problems locating, identifying, and retrieving objects needed for daily activities (e.g., clothes and food items) from familiar storage contexts, such as cupboards and cabinets. This preliminary study assessed a technological system designed to help three people with those problems improve their performance. The technological system, which involved the use of tags with radio frequency identification codes, a smartphone, and a tag reader, aimed to guide the participants in searching and retrieving objects from three different storage units. In practice, the system provided different feedbacks depending on whether the participants were searching (a) in a wrong storage unit, (b) in a wrong shelf/drawer of the right storage unit, or (c) in the right shelf/drawer of the right storage unit. All participants were successful in retrieving objects correctly with the technological system. The results also showed that (a) the participants preferred using the system over a control strategy, (b) were able to switch on and off the system independently, and (b) staff rated the system positively. These preliminary findings suggest that the system might be a useful support tool for people with blindness and intellectual disability.

A Simulation for Managing Retail Inventory Flow Using RFID and Bar Code Technology

ABSTRACTThe increasingly complex retail environment faces many inventory management challenges. Automatic identification and data capture (AIDC) technologies have been applied by retailers to address these challenges, with mixed levels of success. This article presents a classroom simulation of a retail environment in which students utilize a bar code scanner and a radio frequency identification (RFID) reader to manage inventory for the simulated retailer. From the simulation, students gain hands‐on experience with these technologies, learn about the advantages and disadvantages of the technologies, and discuss additional cutting‐edge AIDC technology.

Sensor-based filament fabrication with embedded RFID microchips for 3D printing

Composite filament materials with embedded sensors are increasing in demand to create 3D printed hierarchical sensor structures in a cost-effective and scalable way for the development of wearable and geometry-conforming sensing devices. Traditional methods of encapsulating sensors with polymers are implemented through techniques such as adhesive bonding and potting. For microelectronic device encapsulation, the plastic moulding technologies are employed. However, final products from these methods have geometry constraints and are not easily customizable. This paper presents a methodology of fabrication of polymer filaments embedded with 550-µm radio-frequency identification (RFID) chip using extrusion process for 3D Printing applications. The fabricated filament (3 mm diameter) is manufactured with a 1.5 mm extrusion nozzle specifically designed for this process and controlled by an RFID reader. The RFID sensor filaments produced by this extrusion encapsulation technique were successfully used to produce objects on an existing Fused Deposition Modelling (FDM) 3D printing machine. Such filaments and printed devices are wireless, battery-less, flexible, customizable, and repairable, and hence are advantageous in new sensor applications including the internet of things (IoT). The 3D printed objects produced via this process will have the ability to sense the environment and communicate with reader devices due to their unique embedded RFID codes. This development will subsequently open new avenues for meeting the growth in IoT demands forecast as a pillar of industry 4.0.

18 Wireless Cloud-Based Data Acquisition and Management Tool for Use with Inteli-Straws and Assisted Reproductive Techniques

Inteli-Straw (I-S) devices equipped with radiofrequency identification (RFID) technology were developed for gamete and embryo packaging, storage, and information retrieval to benefit the assisted reproduction industry. The aim of this study was to develop and test software for use with I-S technology. Two types of I-S were used, those with 125 and 134 kHz RFID chips, in conjunction with corresponding wireless RFID readers. Two different RFID chip designs were tested: (1) Mini: 0.25-mL straw, RFID tag dimensions = 1.25 × 7 mm and 1.4 × 8 mm; Standard: 0.5-mL straw, RFID tag dimensions = 2 × 12 mm; and (2) µ-chip (Hitachi Ltd., Tokyo, Japan) of 0.4 mm square and 0.06 mm thick. Inteli-Straw RFID chips can be written or have codes that can be associated with information in a database. The present RFID chips were used with the idChamp DX1 Veterinary & Livestock RFID Reader that uses Bluetooth to connect to an iOS platform for cloud computing. The iScanBrowser (Serialio, TX, USA) LED, an app for an iOS platform for use with a wireless RFID reader, was utilised, as well as a proprietary gamete and embryo database software. The present system allows for quickly accessing the RFID codes from the various I-S gamete and embryo packaging (before or after I-S filling) and entering the data into a computer or cloud-based database that can track their status, movement, metadata, and so on. The ability to acquire I-S information with wireless entry into the cloud-based database was achieved. When the RFID wireless reader detects an I-S, the RFID code is displayed almost immediately (~1 s) in a cell in the software system. The I-S (n = 194) were scanned for automatic database entry. For the wireless-enabled proof of concept, 17 scans of I-S [i.e. RFID chip design 1 (n = 15) and design 2 (n = 2)] were made with wireless scanner detection (< 2.5 cm from RFID reader to I-S) and online database entry with a 100% success rate. By using this I-S method, the present invention provides a wireless, cloud-based system for local or remote access, potentially benefiting both laboratory and field logistics. For AI and embryo transfer, the user can scan an I-S and the information is automatically detected; wireless cloud computing and RFID data crosschecking can occur; and the information can be uploaded to a database for later retrieval or analysis. Further, one can use an iphone or ipad to enter other information such as cow number into the cloud-based database during AI or embryo transfer. The present system can allow for near real-time viewing of the data, locally and remotely, or cross-checking of materials and associated information to reduce errors and improve assisted reproductive technology efficiency.

Multilevel Package Identification Scheme Based on RFID Code and Related Package Message

Radio Frequency Identification (RFID) is one of the key areas of the internet of things (IoT) and widely used in the fields of target identification, security, tracking, anticounterfeiting, and so forth. In some IoT scenario, multilevel package is used to pack the products. The RFID codes of different-level packages imply the subordinate relation. Based on this relation, we can directly obtain the sublevel package code by a package code. It will greatly improve the efficiency of logistics management, especially assisting the tracking and tracing of merchandise. In this paper, a RFID code scheme is introduced to identify different-level packages. With research on the relation of multilevel packages, the subordinate relation of different-level RFID codes is established by recording and storing the inclusion relation between codes in the database. Moreover, the code scheme is applied in Fast Moving Consumer Goods (FMCG) management, which is an example of three-level packages, to verify its feasibility.

수리시설물의 실시간 정보관리를 위한 RFID 및 QR 코드 기반의 모바일 기술 운용성 평가

This study aims to assess the mobile information technology as an alternative means for managing information of irrigation facilities. Traditional irrigation facility management which is operated manually has faced to critical limitations, such as delayed and loss in data handling and facilities misidentification. Real time download, collection, and update the information about the irrigation structure conditions in terms of operation and maintenance can provide a better support of the management efforts. Thus this study suggested mobile information technology using RFID (Radio Frequency IDentification) and QR (Quick Response) code for real time information management of irrigation facilities. This paper describes the applications and implementation results of real-time mobile technology for the field information communication of the irrigation facilities. The system was tested in I-dong irrigation districts in Gyounggi-province, Korea and the assessment of operability demonstrated beneficial usability for inspection of agricultural irrigation facilities in the irrigation district. The tests showed that RFID was preferred method expected to improve operability although these had some limitation. The mobile technologies are expected to increase efficiency and effectiveness of irrigation facilities management.

Effective and Efficient Event Dissemination for RFID Applications

The adoption of radio frequency identification (RFID) tags and devices facilitates the observation and monitoring of event patterns, while highly temporal restrained RFID data further make events complicated. Although the existing Pub/Sub systems can help distributed applications monitor and disseminate interesting events, they are unable to express RFID-related events directly. Extending a system for new RFID requirements not only needs a lot of work, but also provides no performance guarantees. It is, therefore, necessary to design and implement an effective and efficient Pub/Sub system in order to capture and disseminate RFID-related events. This paper presents a composite subscription specification for RFID-related application scenarios. It enables the subscription of predicates for RFID code as well as various complex events. Moreover, this paper proposes the algorithms for RFID-code subscription matching and complex events detection which have been implemented in our Pub/Sub system, OncePubSub. Also, experiments were conducted to quantify the performance and overhead of the above algorithms. Performance evaluation results indicate that OncePubSub is more efficient than SIENA-and JESS-based systems.

Engineering Management-Focused Radio Frequency Identification (RFID) Model Solutions

In comparison to the well known and widely used UPC bar codes, that offer generic object-level visibility, RFID tags, also referred to as the ePCs: electronic product codes with a 96-bit identification method, offer unique, item level visibility throughout the entire local and global supply chain. This is because UPC codes are typically product and manufacturer specific, whereas RFID codes are generic, truly unique IDs. This is why RFID technologies with the appropriate information systems and information technology (IS/IT) infrastructure help both major distributors and manufacturers, as well as other logistics operations, such as the electronic manufacturing industries, defense industries, automotive, pharmaceutical industries, and others, dealing with complex, global supply chains in which products and product manufacture, assembly and shipments must be traced and identified in a non-contact, wireless fashion. Engineering management is collaborating with IS/IT professionals to model and integrate RFID-related information systems engineering requirements into computer networks, because of reducing cost, increasing security, or safety, or because parts are subject to corrosion, or food/medicine is subject to quality degradation, or other reasons. All of these requirements point to an automated, wireless-readable sensory-based identification method, and network, that offers more functionalities and is significantly 'smarter' than the well known bar code or the unified product code (UPC). RFIDs are available as passive and/or active radio read/write sensor-packages with active read (and often write) capabilities in relatively large areas (like a large distribution center warehouse, or a containership), all performed automatically, supervised by computers and communicated in a wireless fashion over secure intranets. The attraction to an engineering management-focused supply chain manager is that when the RFID network is integrated with the factories' material resource IT management systems, accurate information can be obtained on all tagged parts in close to real-time, throughout the entire supply-chain. This can include the globally distributed factories, as well as information about parts and assemblies during shipment, including in-transit. This is why RFID represents great research, technology, as well as huge business opportunities. In this paper we introduce some of the most important engineering management information system modeling principles, challenges and solutions, that RFID researchers, implementers and users should keep in mind when developing such systems, and/or planning for such applications.
