Abstract: This letter introduces a micro-electromechanical system (MEMS) resonant pressure gauge based on aluminum nitride piezoelectric resonators that can operate in an atmospheric environment. The ...

Your car’s performance depends on precise control of air, fuel, and spark, and vacuum leaks quietly disrupt that balance.

Abstract: A novel and highly sensitive vacuum gauge based on a micromachined AT-cut quartz bulk acoustic wave (BAW) resonator diaphragm is presented. Pressure is sensed by monitoring frequency shifts ...

Timing is crucial for investment success; static buy-and-hold strategies often underperform due to market cycles and prolonged downturns. Three proprietary portfolio models—Active Premium, ...
