Portable Radar for Noncontact Heart Rate Monitoring and Estrus Detection in Dairy Cows
This study introduces a portable radar system for real‐time monitoring of respiratory and heart rates in dairy cows. It uses millimeter‐wave Frequency Modulated Continuous Wave (FMCW) radar to perform noncontact physiological sensing, reducing behavioral disturbance. The radar system's design prioritizes portability, cost‐effectiveness, and robustness,

A System for Retrofitting Conventional MRI Systems for Simultaneous Multinuclear MRI/MRS
We present a low‐cost system for retrofitting conventional narrow‐band MRI spectrometers with simultaneous multinuclear capability using heterodyne frequency translation. The system supports up to four nuclei and 16 receive channels, with reconfigurable transmit modes and inherent phase stability through a shared local oscillator architecture ...
