| 20120199123 | INTERMITTENT DOSING OF NITRIC OXIDE GAS - A method and corresponding device are described for combating microbes and infections by delivering intermittent high doses of nitric oxide to a mammal for a period of time and which cycles between high and low concentration of nitric oxide gas. The high concentration of nitric oxide is preferably delivered intermittently for brief periods of time that are interspersed with periods of time with either no nitric oxide delivery or lower concentrations of nitric oxide. The method is advantageous because at higher concentration, nitric oxide gas overwhelms the defense mechanism of pathogens that use the mammalian body to replenish their thiol defense system. A lower dose or concentration of nitric oxide gas delivered in between the bursts of high concentration nitric oxide maintains nitrosative stress pressure on the pathogens and also reduces the risk of toxicity of nitric oxide gas. | 08-09-2012 |

| 20140130801 | ELECTRONIC FLUID FLOW CONTROLS WITH INTEGRATED MANUAL FLUID FLOW CONTROLS - In various embodiments, a flow selector of a fluid flow control system may be used to select a flow rate of a fluid. When the system is in an electronic mode, an encoder may electronically encode the fluid flow selection. A controller may receive the electronically encoded flow selection and transmit a corresponding control signal to an electronic valve to allow the fluid to flow at the selected flow rate. An engagement device, such as a clutch, may disengage the flow selector from a mechanical valve when the fluid flow control system enters a manual mode. When the system is in a manual mode, the engagement device may engage the flow selector with the mechanical valve, allowing the flow selector to directly control the flow rate of the fluid through the mechanical valve.
