This paper proposes a cooperative real-time positioning system to solve both indoor and outdoor location tracking problem for disaster aid, we conduct a detailed overview of pre-existing indoor positioning systems, give architecture of cooperative positioning system, and introduce the least square method to improve accuracy of time difference of arrival(More)
With recent advances in wireless communication and low-power miniaturized biomedical sensor and semiconductor technologies, wireless body area networks (WBAN) has become an integral part of the disaster aid system. Wearable vital sign sensors can track patients'status and location, thus enhancing disaster rescue efficiency. In the past few years, most of(More)
We investigate the implementation of field-weakening control for interior permanent magnet synchronous motor (IPMSM), and analyze the algorithm of field-weakening control in d-q axes. To deal with the problem that the dc-link voltage is not fully utilized when the voltage regulation is employed, we propose a new field-weakening scheme based on the(More)
