  • LANDING ZONE DESIGNATORS
    Publication number: 20230227177
    Abstract: A landing zone designator system includes two sets of antennas; the first set of antennas defines a first vertical lobe at a first known orientation to the landing pad and the second set of antennas defines a second vertical lobe at a second known orientation to the landing pad. A VTOL aircraft including two antennas tracks the vertical lobes to align the aircraft to the center of the landing pad. The aircraft antennas can be rotated or repositioned dynamically to accommodate the orientation of the aircraft.

  • Temperature swing humidity collector using powerplant waste heat
    Patent number: 6863711
    Abstract: A system for recovering water from the atmosphere includes water sorbent assembly composed of a water adsorbent material and a heat exchanger. The water adsorbent material traps water present within the air drawn through the sorbent assembly. Once the sorbent assembly is fully saturated, exhaust gases generated from a power plant are routed through a heat exchanger in thermal contact with the water adsorbent material to remove water within the sorbent assembly into a condenser, and from the condenser to a water storage container.
