Subcategory(s):

The invention is a lightweight device that remains tethered in place to a base unit on the ground by cables, can be equipped with various types of surveillance equipment, and can quickly elevate vertically into the air by simple controls.

Category(s):
Subcategory(s):
The invention describes a small, light-weight, low-power, multichannel radio that receives signals from ground based commercially-licensed broadcast transmitters and analyzes these signals to estimate the receiver's position, groundspeed and heading. Other technologies providing navigation data from ground-based RF broadcasters require a local ground based reference station.
 
Development status: completed system-level simulation; awaiting experimental proof-of-concept
Category(s):

The invention is a composite system useful for indicating and preventing fatigue on essentially any metallic structure.

Category(s):
Subcategory(s):

A novel sensor design allows capture of angular fluid flow with greater accuracy than the conventional Pitot-type probe currently in use in commercial and military aircraft

Category(s):
Subcategory(s):
A lightweight, laser-based sensor system that augments an onboard autopilot with accurate altitude and attitude measurements, enabling automated landing of uncrewed aerial vehicles (UAVs).
 
Development status: completed system-level simulation; exp. proof-of-concept in lab (1-Hz meas rate)
