This proposal is for the development of precision transducers for use in an electronic stethoscope and an accelerometer for measurement of vascular sounds generated by stenoses and aneurysms, fetal heart rates and tissue motion. the instrument will include an infrared data transmission link for… More

The primary objective is to make and to clinically test a computer-aided, portable myotatic reflex measurement system for use in clinical neurology and clinical research on humans and for laboratory research on large animals. it will consist of a hand-held, instrumented reflex gun containing a… More

Combining the stability of quartz and the process micromachining, it may be possible to develop cost effective inertial navigation sensors (INS). Linear position can be determined from passive or active vibrating beam type accelerometers while rotation can be determined from resonating tuning fork… More

Conventional structural evaluation methods often fail to provide accurate defect measurement of large civil engineering structures. innovative slope mode and modal energy transfer sensors and measuring systems that would make structural evaluation more feasible and accurate are being developed. … More

In Phase I, the feasibility of adaptive-passive devices to control noise and vibration is studied. In many applications, adaptive- passive devices may be as effective as fully active control but without the attendant drawbacks. Compared to fully active systems, the adaptive-passive system consumes… More

Researchers are creating innovative findings to passive damping and active vibration control technologies which play a major role in the success of designs of dynamic structures. unique opportunities exist with the use of modules or patches incorporating piezoelectric material and microelectronic… More
