Study of epilepsy in free moving animals provides the accurate information of this disease. While it has been proved that hemodynamic changes are greatly involved in epileptic seizures, methods for hemodynamic detection on free moving animals is limited. In this work, we integrated a photoacsoutic sensor and an EEG system into a small device that can be attached on the rat head, and for the first...
The battery module (BM), which integrates battery string with peak current charging, constant voltage charging and balancing control together, presents in this paper. In order to obtain smoothly transitive over each charging phase, the small signal model of the peak current charging control was investigated and designed. Furthermore, a low cost 8 bits microcontroller PIC16F877A controls and monitors...
Autonomous landing for Unmanned Aerial Vehicle is an important direction in the field of UAV research. Currently, relative GNC methods for aerial vehicle landing including GPS (Global Position System), INS (Inertial Navigation System) and ILS (instrument landing system) can't fully satisfy the requirements for UAV autonomous landing on the runway or un-cooperation environment. With the gradual progress...
Detecting and monitoring emissions from flaring gamma-ray sources in the very-high-energy (VHE, > 100GeV) band is a very important topic in gamma-ray astronomy. The ARGO-YBJ detector is characterized by a high duty cycle and a wide field of view. Therefore, it is particularly capable of detecting flares from extragalactic objects. Based on fast reconstruction and analysis, real-time monitoring...
The effectiveness of an imaging technique is often based on the ability to image quantitatively both morphological and physiological functions of the tissue. Here we present several ultrasound-based imaging techniques capable of visualizing both structural and functional properties of living tissue. Each imaging system utilizes custom-made, targeted nanoparticles developed to probe specific molecular...
Technology advantages of wireless sensor networks have shown great deal of promises in various biomedical applications. In this paper we introduced a specially-designed body sensor networks (BSN) development platform for on-body physiological measurements and body-proximal wireless data communications. The BSN platform we have developed insofar include BSN node boards, a photoplethysmograph sensor...
A technique for monitoring electrostatic charge accumulation inside a hard disk drive (HDD) is described: a miniature charged plate is built into the top cover of the HDD, connected to a charged plate monitor. Experiments show that the miniature plate technique can be used for detection and measurement of the voltage induced by the charge generated inside the grounded enclosure of a hard drive.
