In various representative aspects, an airborne delivery system according to various aspects of the present invention comprises a container and an autorotating rotor system. The container may contain contents, and the rotor system facilitates control of at least a portion of the flight of the airborne system and the descent. Exemplary features may include a guidance system, for example to guide and control the airborne system, and a wing for gliding.

Methods and apparatus for airborne unpowered rotor delivery systems

A communication system () includes a transmitter () with (i) a transmitter photonic crystal () having a waveguide () and multiple cavities (, and) spaced along the waveguide (); (ii) a light source (); and (iii) a controller () that controls the cavities (, and) to translate multiple electronic data bits to optical data bits simultaneously in respective cavities (, and) illuminated by the light source (). A corresponding receiver () includes a receiver photonic crystal () having a data/key waveguide () for receiving a data/key signal and a latch waveguide () for receiving a latch signal. The photonic crystal () also includes data readout cavities (, and) and lock cavities (, and) adapted to compare the key bits to respective lock bits. The data readout cavities (, and) are spaced to read out the data bits simultaneously if (a) the data/key signal and the latch signal are received simultaneously, (b) the data/key signal and the latch signal have the same length, and (c) the key bits in the key/data signal match the lock bits.
