It is important to avoid secondary brain injury after Traumatic brain injury (TBI) in clinical. Cerebral perfusion pressure (CPP) is associated with blood flow into the brain, and indirectly reflects the cerebral ischemia and oxygenation. However, it is invasive and is inconvenient for continuous monitoring. Recently, near infrared spectroscopy (NIRS) has been widely applied for monitoring cerebral...
Firstly, the multi-smart car formation control system is designed by using distributed control architecture. The wireless communications, the magnetic field sensors, motor drives and other hardware modules are designed. The smart car navigation is achieved by magnetic field detection. Then the multi-smart car cooperative control self-organizing wireless communication network is designed by ZigBee...
There is a growing demand for implementing low-power and low-cost wireless sub-soil sensing systems to support precision agriculture. This paper describes an RFID sub-soil system that is capable of hosting a range of sensors and communicating their measurements wirelessly to farming vehicles. In addition to providing an overview of the system, the paper presents the high-level design of the RFID reader...
In this paper aims on adaptive resource allocation in maximize system throughput under total power and target bit error rate (BER) constraints propose the algorithms of adaptive resource allocation on OFDM-based (Orthogonal Frequency Division Multiplexing) cooperative communication systems. For single-source, destination and relay node environment. the optimal power allocation for the sub carriers...
This paper proposes a surface acoustic wave (SAW) passive wireless sensor system for monitoring the temperature of the electric cord connectors. The low-loss sensor consists of a temperature-sensing high-Q SAW resonator, a small antenna and a matching circuit. The resonant frequency of the SAW sensor is varied with the temperature. While the interrogational signal is a sinusoidal burst, the response...
