    摘要： A single one time use valve, based on a Shape Memory Alloy (hereinafter—SMA) actuating component, wherein the valve comprises a nipple component given to shearing and shoving from the instant of its being severed off, in a manner that enables passage of the gas or the liquid from the valve's inlet flow opening to the valve's outlet flow opening wherein the valve is a valve of the normally closed type, or enables stopping of said gas or liquid passage from the inlet flow opening to the outlet flow opening, wherein the valve is a valve of the normally open type, and wherein the valve is characterized by that the inlet flow opening and outlet flow opening are formed substantially on at least one plain, that extends in its direction wherein it is substantially orthogonal to the valve's house assembly lengthwise axis and wherein a physical demarcation exists all the time between the gas or liquid to the valve's SMA made actuating component.

    摘要： 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.
