Optimal Head-mounted IMU Placement for Heart Rate Detection Using Ballistography.

Continuous and accurate heart rate monitoring is pivotal for the early detection of cardiovascular conditions. Traditional heart rate sensing methods, such as the use of adhesive electrocardiogram (ECG) electrodes, often fall short in terms of comfort and convenience for everyday wear and continuous monitoring. Ballistocardiography (BCG), a non-invasive alternative, offers a promising solution by measuring the body's mechanical reactions to the ejected blood by the heart during cardiac cycles.

Impairment Screening Utilizing Biophysical Measurements and Machine Learning Algorithms.

Drug recognition expert (DRE) officers employ a set of tests to investigate drivers who are under impairment and to determine the type of drug that they have used. Horizontal Gaze Nystagmus (HGN), Walk and Turn (WAT), and One Leg Stand (OLS) are the main three tests included in the Standardized Field Sobriety Tests (SFSTs), which lead the officers to evaluate the sobriety of drivers. Performing these tests requires trained officers, but the final decision may still be subjective.
