Air quality monitoring is critical for environmental health and public safety. Traditional monitoring methods rely on passive and active air sampling techniques, which, while effective, are cumbersome, expensive and limited with respect to real-time data and comprehensive analyses. In high-risk environments, such as hospital or care settings, and food...

In many production systems like semiconductor manufacturing, food industry, and battery production, the amount of time a part can spend in successive buffers is limited in many production systems because of possible quality concerns. If a part's residence time exceeds these limits, it must be trashed, which results in waste and lost output. To prevent...

Current portable and wearable devices use fingerprint analysis for secure authentication. The fingerprint pattern systems analyze only the surface morphology of the fingerprint, making it easy for hackers to spoof and bypass authentication. RF signals can collect tissue information beyond the surface of the finger and can provide increased security...
