ultra low power uwb rfid system for Precise Location aware applications
Wireless Communications and Networking Conference, 2012Co-Authors: Yuan Zhou, Choi Look Law, Jingjing XiaAbstract:Ultra low-power radio-frequency identification (RFID) tag with precision localization is often the enabling technology for Location-aware sensor applications. Impulse-Radio Ultra-Wideband (IR-UWB) is a promising technology to fulfill the usage requirements in indoor cluttered environment. An ultra low-power Precise UWB-RFID localization system is proposed in this paper. The RFID tag is a transmitter comprising of a micro-controller board and a UWB impulse radio board. Power saving and precision localization is achieved by optimization of the circuit design for ultra short pulses as well as system architecture and operation. When 1 s sleep mode is incorporated with 0.72 ms active mode, the tag consumes on average 6.8 uA when pulsing at 3.3 MHz rate with 15.5 dBm peak transmit power. The transmitted pulse is captured by low-cost energy-detection receivers at the locator. Measurement in a 6m×6m typical indoor environment demonstrates that the proposed system is able to achieve positioning accuracy of 10 cm. Due to the high sensitivity of the receiver (−71 dBm), the proposed system can reach a potential reading range of over 100 meters. The ultra low-power consumption, accurate ranging and positioning result, and long reading distance makes the proposed system suitable for a variety of intelligent sensor applications.

Journal of Medical Systems, 2005Co-Authors: Kenta Hori, Yasuhiko Ozaki, Tomohiro Kuroda, Hiroshi Oyama, Takehiko Nakamura, Takashi TakahashiAbstract:For faultless collaboration among the surgeon, surgical staffs, and surgical robots in telesurgery, communication must include environmental information of the remote operating room, such as behavior of robots and staffs, vital information of a patient, named supporting information, in addition to view of surgical field. "Surgical Cockpit System, " which is a telesurgery support system that has been developed by the authors, is mainly focused on supporting information exchange between remote sites. Live video presentation is important technology for Surgical Cockpit System. Visualization method to give Precise Location/posture of surgical instruments is indispensable for accurate control and faultless operation.

humancentric applications of Precise Location based services
International Conference on e-Business Engineering, 2005Co-Authors: L Perusco, Katina MichaelAbstract:This paper focuses on the growing need to consider the implications of humancentric applications of Precise Location based services (LBS). As newer positioning technologies are introduced into the market with a greater level of Location accuracy, and existing technologies are utilized in an integrated fashion to overcome limitations, issues pertaining to the use and potential misuse of Location information rise to the fore. The scenario planning methodology provides a robust approach within which to consider future possibilities based on current market developments. To this end, document and content analysis play an important role in the collection of facts used to illustrate a given set of scenarios. The contribution of this paper is in providing adequate evidence toward Precise LBS and in identifying those attributes that will guide the formation of the narrative descriptions in future research. The preliminary results of the study indicate that societal, ethical and legal implications need to be given greater attention as Precise LBS applications will be increasingly used in the tagging, tracking and tracing of humans
