Sensor systems with volumetric coverage of large areas are in high demand for general infrastructure protection. This paper describes a radio frequency communication system that allows for real-time evaluation of changes to established field patterns for the purpose of locating and tracking unwanted intruders. It is based on high confidence probabilistic algorithms and protocols that sample the environment...
This paper introduces a new scheme on multifunction wireless medical surveillance system based on Radio Frequency (RF), General Packet Radio Service(GPRS) wireless communication protocol and the high performance Field Programmable Gate Array(FPGA) chip. This system receives real-time human physiological parameters such as blood pressure, body temperature, electro cardio signal and pulse and so on...
Recently, several papers for reading meters remotely using RFID/USN technologies have been presented. In the case of wireless water meters, there has been neither commercial product nor paper. In this paper, we describe the design and implementation of wireless digital water meter with low power consumption. We use magnetic hole sensors to compute the amount of water consumption. The meter of water...
