A mobile communication system which consists of a plurality of MANETs and nodes, which comprises a transceiver at each node. Each transceiver is a combination of a hopping transmitter operating according to a predetermined hopping sequence and rate and a wideband reference receiver, that can simultaneously receive at once, the whole operating band assigned to the system. Each transceiver further includes a circuitry for reallocating simultaneously receiving channels, dynamically spread over a wideband frequency range and circuitry for determining transmission hopping patterns to use the least possible number of frequencies according to the active population status of nodes that belong to the plurality of MANETs. This circuitry is also used for adapting the transmission scheme of the alien transceivers by finding time slots, in which a counterpart receiver at each remaining active node is not transmitting and a frequency channel, in which no other active node, neighboring the counterpart receiver transmits, while determining proper transmission frequency for each transmitting node.

A constraint problem may be represented as a digital circuit comprising at least one gate and at least one constrained input or at least one constrained output, or a combination of at least one constrained input and at least one constrained output. A matrix may be generated for each of the at least one gates. A constraint matrix may be generated for the at least one constrained input, the at least one constrained output, or the combination of at least one constrained input and at least one constrained output. A final matrix comprising a combination of each matrix for each of the at least one gates and the constraint matrix may be generated. The final matrix may be translated into an energy representation useable by a quantum computer. The energy of the energy representation may be minimized to generate a q-bit output, and a result of the constraint problem may be determined based on the q-bit output.

A shutter mechanism for covering a wings spreading opening formed in an airborne body and a method for covering such opening while implementing the shutter mechanism, wherein the shutter comprises at least one flap assembly, and wherein from the instant that a deployed wing of the airborne body passed and moved over it, it is biased by traction of at least one springy element to an angular motion around an axis, unto a condition where the flap component of the assembly is positioned so that it is substantially conformal to the outline of the outer surface of the fuselage of the airborne body and while it covers the opening through which the wing passed in its motion; and from an instant that the wing returned and connected to the flap component of the assembly, the flap is biased to an angular motion counter the spring, to the state that the wing returns and is relocated on its top surface.
