Abstract: A method for realizing network access authentication, wherein a network access authentication device pre-storing a system integrity value of a device waiting to access and a correspondence between each device waiting to access and its system integrity value. When the device waiting to access needs to access the network, it acquires its current system integrity value, and sends the current system integrity value to the network access authentication device; the network access authentication device judges whether the received current system integrity value of the device waiting to access and its stored integrity value of the device waiting to access are identical or not, and in a case where the received current system integrity value of the device waiting to access and its stored integrity value of the device waiting to access are identical, it determines that the network access is authenticated.

Abstract: An oxygen concentrator comprises an oxygen reservoir and adsorbent columns that each have an inlet, an outlet, and a bed of adsorbent material. The concentrator also comprises an air inlet, an exhaust outlet, and a vacuum pump for pumping nitrogen rich gas from one of the column inlets to the exhaust outlet. A product control pump pumps oxygen rich gas from one of the column outlets to the oxygen reservoir. A control valve controls flow in and out of the columns by selectively connecting the air inlet to one column inlet, connecting the vacuum pump to another column inlet, and connecting the product control pump to a column outlet. A motor drives the vacuum pump and control valve to produce vacuum swing adsorption (VSA) cycles in which oxygen-rich product gas is separated and accumulated in the reservoir.

Abstract: A two-step, self-regulating valve (16) controls gas flow from a gas cylinder (12) in a high pressure system. The valve (16) includes a valve body (24), a piston (26), a plug (28), a valve actuator (34), and a piston actuator (32). The piston (26) is movable within the valve body (24) along an axis between a first and a second position. The plug (28) is movable within the valve body (24) along the axis between a valve closed position, a partially open position, and a fully open position. The valve actuator (34) allows the plug (28) to move from the valve closed position to the partially open position. The piston actuator (32) causes the piston (26) to move from the first position to the second position when a gas pressure in the gas cylinder (12) is less than a setpoint. When the piston (26) moves to the second position, the piston (26) allows the plug (28) to move from the partially open position to the fully open position.
