Cardiac Scan: Continuous Computer User Authentication
Continuous computer user authentication is achieved using DC-coupled continuous-wave radar images of the user's unique cardiac motion signature. Background: Continuous authentication improves upon one-pass validation by continuously verifying over the lifetime of a session that the system is operated by the same user as at initial login....

Radar Doppler Detecting Good Codes for Improved Signal Accuracy
A method improving the handling of Doppler shifts allowing radar systems to accurately detect and track objects. Background: The world does not stand still for us to measure it. It’s a dynamic place and radar needs to measure objects in motion. Good radar codes maintain strong mainlobe signals and small sidelobes in the presence of...

Graphene-based Plasmonic Nano-transceiver for Terahertz Band Communication
Current wireless systems operate at frequencies around or below 5 GHz. As the frequency increases, as does the bandwidth, and ultimately, as do the achievable data transfer rates. However, as frequency increases, so does propagation loss, or the loss of power density, from the expansion of the radio wave in free space, ultimately hindering the ability...

Predictive Indicator System for CO2 Scrubber Endurance
For scuba diving, a microcontroller and sensors to monitor non-hygroscopic soda lime usage in closed circuit breathing apparatus and calculate the available remaining dive time. Non-hygroscopic soda lime is used to remove exhaled carbon dioxide (CO2) in closed circuit breathing apparatus. As a diver exerts him/herself while swimming, the soda lime...
