Abstract: 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.

Abstract: A communication system (20) includes a transmitter (22) with (i) a transmitter photonic crystal (30) having a waveguide (40) and multiple cavities (42, 44, and 46) spaced along the waveguide (40); (ii) a light source (32); and (iii) a controller (34) that controls the cavities (42, 44, and 46) to translate multiple electronic data bits to optical data bits simultaneously in respective cavities (42, 44, and 46) illuminated by the light source (32). A corresponding receiver (24) includes a receiver photonic crystal (92) having a data/key waveguide (104) for receiving a data/key signal and a latch waveguide (106) for receiving a latch signal. The photonic crystal (92) also includes data readout cavities (110, 112, 114, and 116) and lock cavities (160, 162, and 164) adapted to compare the key bits to respective lock bits.
