Research at Auto-ID covers a wide range of topics. This page introduces the abstract for each research. About past researches, please look at this page.
- RFID(Radio Frequency Identification)
- In recent years, RFID became an essential technology that takes the place of the traditional bar code in terms of auto identification. RFID returns a unique ID written to an object via the radio signals of the reader. RFID enables auto identification of individual things by receiving this communication with the reader.
- WiMAX(Worldwide Interoperability for Microwave Access)
- WiMAX is a telecommunication protocol which provides fixed and mobile internet access to the medium-scale areas in cities, rural towns, and mountainous districts, etc. UQ Communications Inc. commercially provides the communication service starting in 2011, with the performance of max 40Mbpx at downlink and min 10 Mbps at uplink.
- ZigBee is one of the short-range radio communication protocols for home network and using low-power and multihop or ad-hoc network. ZigBee is provided the specification by ZigBee Alliance. Zigbee is based on the IEEE 802.15.4 standard on PHY and MAC Layer.
A bidirectional medication support system connecting home care patients and medical staff
In medical fields, there are many patients who wish to be taken care of at their own homes. However, medical care at homes requires self-management of diseases and illnesses by the patients themselves. Thus, patients are encountering many difficulties, and one of the biggest issues among them is the management of medication.
In this research, a system using sensor networks for monitoring the open-close status of a pill box was designed and implemented. The proposed system will take an approach to improve the medication adherence by enabling bidirectional communication between the patient and medical staff, through the monitoring and the feedback.
In order to evaluate the effectiveness of the system, a demonstration experiment was conducted on 3 patients over a 5 month period. As a result of the experiment, the system was successful in providing the medical staff with an accurate medication history, enabling them to visually analyze their patients’ medication. Also, not only did it reduce the frequency of emergency responses by nurses, the feedbacks improved the rate of missed dosages.
According to the evaluations, the proposed system was confirmed effective in assisting patients to manage their medication in home medical care situations. Thus, this research may establish a beachhead in expanding home medical care.(shiori)
RF tag group coding
RFID is an essential technology to uniquely identifying physical objects. In many practical business processes that utilize RFID, we confirm not only individual objects but also if there is any missing objects and no extra objects in a group of objects.
While the identification of individual object is done by using RFID, group verifications are usually done by looking up a shipping list or corresponding EDI data which require a network connection. In this research, we study a novel group verification method which doesn’t require the network connection. This method uses “writable memory”, which is one of RF tag’s features, and “coding theory”, which is used for information communication.
This research includes development/improvement of coding scheme for group verification, implementation of the coding scheme with physical RFID interrogator, and development of equipments required for experimental evaluations of coding scheme.(sat3)
