This paper proposes and demonstrates a dual-band Wireless Communication and Power Transmission (WiCoPT) system for a wireless health monitoring sensor network in Reusable Vehicle Test (RVT). The proposed dual-band WiCoPT system employs 25 GHz-band for uplink and data transfer and 5 GHz-band for downlink and power transfer, resulting in an efficient wireless sensor system. The paper also analyzed the...
It is often difficult for visually impaired persons to walk outside to his or her destination. In this paper, we develop a cane with a built-in haptic interface for use by visually impaired persons. The cane is paired with IC tags buried underground (e.g., under street pavement). The haptic interface is controlled with a position and velocity control system that accurately indicates four directions...
This paper offers a significant evaluation of reader's placement for two wheeled robots to estimate their posture from a lattice of RFID tags. RFID systems where IC tags are installed under/on floors have widely been utilized in recent years as the next positioning infrastructure. The readers' antennas should be properly configured on a robot so that such an environment can give full play to its potential...
In this paper, we propose a novel method using read-time of IC tags to reduce the localization error of an RFID navigation system. In order to reduce localization error, many approaches have been introduced. However, they do not deal with the problems that arise when the antenna can read at most one tag at any given moment. Using this, our passive RFID system is able to estimate the robot's location...
Government has to hurry up to build accessible facilities for elderly people and people who has disabilities. Because our country is experiencing an aging society, for example, pedestrian space should be safe and give a relief. One of the methods to ensure this society is to obtain absolute position with high accuracy. Therefore, we suggested here to make Universal Map (UM) with a large scale (1/500...
There are about 300,000 visually impaired persons in Japan. Most of them are old persons and, cannot become skillful in using a white cane, even if they make effort to learn how to use a white cane. Therefore, some guiding system that supports the independent activities of the visually impaired are required. In this paper, we will describe about a developed white cane system that supports the independent...

An increasing number of companies want to improve product traceability for several reasons: to meet stricter government regulations about food and medical safety, to cope with ever-stronger consumer demands to know exactly what they are buying, and to improve and protect the company's brand value through more transparent business operations. Two aspects of traceability are technically important: (1)...
