US Patent 11027850 Elevation tracking device

The systems and methods provided herein are directed to a device for tracking a jumper's elevation during a parachute jump. The device includes an active sensor for monitoring a distance to the ground, which is disposed at an angle and transmitted from the jumper's calf to reduce the chance of self-obstruction. The device notifies the jumper in one of several ways when a threshold elevation is reached, and may take additional automated actions at particular elevation thresholds.
