Abstract: Apparatus for providing communication between ground-based User Equipment (UE) and at least one core network and a method for providing wireless communication between ground-based User Equipment (UE) and at least one core network are disclosed. The apparatus for providing communication between ground-based User Equipment (UE) and at least one core network comprises a plurality of low earth orbit satellites each comprising at least one satellite-based optical transmitter element and at least one satellite-based optical receiver element for providing at least one optical communication link; and at least one aerial vehicle comprising at least one aerial vehicle based optical transmitter element and at least one aerial vehicle based optical receiver element for providing at least one optical communication link and at least one directional antenna for providing a wireless communication link to a ground-based station and/or mobile UE.

Abstract: An information processing system includes a digital computing system, an analog processing device with an arrangement for converting electrical information to information of analog form, and an arrangement responsive to the analog information energy for producing output electrical information. Output data from the digital computing system is applied to the analog processing system via a D/A converter, and an A/D converter applies the output electrical information to the digital computing system. Data modified by the analog processing system may be employed to supplement data applied thereto in a random manner, or in a manner with a known transfer function, in order to introduce perturbations in the data to aid in subsequent processing thereof in the digital computing system.

Abstract: An audio sound modification system for modifying the output sound signals of a sound synthesizer comprises a microcomputer connected to receive signals from the synthesizer and to output modified sound signals. The microcomputer comprises a display device, and displays an image on the display device that has motion, color and shade characteristics. An operator input is also provided. The microcomputer is responsive to first, second and third different input signals from the operator input for modifying first, second and third different characteristics of the received signals and for modifying the motion, color and shade characteristics of the image, respectively.

Abstract: In a method and apparatus for encoding signals, signals are passed through a body of a material that modifies a characteristic of signals passing therethrough, such as an acousto-electromagnetic. Energy is applied to the body for establishing a standing wave therein, so that the standing wave controls the passage of signals through said body. The energy may be applied by a piezoelectric element. The body or the piezoelectric element may be removable, to form an encoding key.
