International Classification:

B64C 39/02
G05D 1/10

Abstract:

An unmanned aerial vehicle (UAV) launch system includes a launch container including a housing defining an internal chamber. A UAV includes a main body defining an inflatable envelope. The UAV is configured to be contained within the internal chamber. The main body is in a deflated state when the UAV is contained within the internal chamber. A reactant is configured to react with water to produce a lifting gas. The inflatable envelope is configured to be inflated by the lifting gas in response to the reactant reacting with the water to deploy the UAV from the launch container.

International Classification:

G01S 11/10
G01S 19/29

Abstract:

Systems, methods, and devices are disclosed herein for Doppler based position estimation. Systems may include an antenna configured to receive a radio frequency (RF) signal from an emitter, and configured to generate an output signal based on the received RF signal. Systems may also include a receiver configured to receive the output signal from the antenna. The receiver may include one or more processors configured to identify a plurality of initial conditions for a plurality of state variables associated with the emitter, obtain a measurement of the RF signal from the emitter and an estimate of an uncertainty associated with the measurement, and generate an output based, at least in part, on an updated estimate of the plurality of state variables, the output identifying a position, velocity, and carrier frequency of the emitter. Systems may also include a communications interface configured to communicatively couple the antenna with the receiver.

Inventors:

Michael Greenfield - Boca Raton FL, US

International Classification:

B63C 11/26
B63B 22/00

Abstract:

A multi-directional signal assembly includes a signal display assembly having one or more display surface, and at least one signal indicia affixed to each display surface. The multi-directional display assembly comprises a buoyant construction such that the signal indicia affixed to the display surface(s) are readily visible above the surface of a body of water in which the assembly is deployed. A counterweight assembly is mounted to the signal display assembly to maintain the signal display assembly in a substantially upright, operative orientation when deployed. An illumination assembly comprising one or more illumination member is mounted to the signal display assembly, and is actuated to increase visibility of the signal display assembly while it is deployed on the surface of a body of water.
