Tags based on surface acoustic wave techniques have a great amount of potential for application in radio frequency identification because of their characteristics of wireless sensing and completely passive operation. Since time domain sampling requires high-speed radio frequency switches in the transmitter and fast data acquisition in the receiver, frequency domain sampling (FDS) is used for measurement...
In DAQ systems for modern high energy physics, as a subsystem, the read out system which takes data from and transfers commands to the front-end electronic systems must be capable to meet the need of high-speed and real-time. In the DAQ system of the Beijing Spectrometer III (BES III) project, the read out system is designed to be based on an embedded and real-time computer system. To define and construct...
The authors have developed a portable, microprocessor-based data-acquisition system to measure pressures between the foot and shoe of ambulatory subjects. They attached seven pressure sensors to the surface of each insole of a pair of extra-deep shoes. They were located under the center of the heel, the five metatarsal heads, and the big toe of each foot. This system continuously collects raw pressure...
