| Number | Title | Issue Date |
| 7096888 | Fluidic pulse generator system A fluidic pulse generator system includes two fluidic diverter valves that are both controlled by a single fluidic pilot valve. The fluidic pilot valve and the two fluidic diverter valves are each adapted to receive a flow of pressurized fluid. The flow of pressuriz... | 08/29/2006 |
| 7055541 | Method and mechanism for producing suction and periodic excitation flow A method and mechanism of producing a suction and periodic excitation flow. The method includes providing fluid flow from jet port with diameter dl at a controlled input pressure (Pin), directing the flow to a conduit with diameter d2, >d1, allowing additional fluid... | 06/06/2006 |
| 7034700 | Solid state electronic pressure switch An electronic single pole double throw switch has two states. In each state, one of the lamps is on and the other lamp is off. In the electronic switch, the voltage, which is at the output terminal of the lamp that is off is utilized to drive a low voltage regulator... | 04/25/2006 |
| 6779559 | Non-mechanical valves for fluidic systems Methods devices and systems that employ non-mechanical valve modules for controlling directing fluid and other material movement through integrated microscale channel network. These non-mechanical valve modules apply forces that counter the driving forces existing t... | 08/24/2004 |
| 6695009 | Microfluidic methods, devices and systems for in situ material concentration Methods of concentrating materials within microfluidic channel networks by moving materials into regions in which overall velocities of the material are reduced, resulting in stacking of the material within those reduced velocity regions. These methods, d... | 02/24/2004 |
| 6681788 | Non-mechanical valves for fluidic systems Methods devices and systems that employ non-mechanical valve modules for controllably directing fluid and other material movement through integrated microscale channel networks. These non-mechanical valve modules apply forces that counter the driving forc... | 01/27/2004 |
| 4678009 | Fluidic complementary gain changing circuit A fluidic complementary gain changing circuit has three laminar proportio amplifiers, one of which supplies fluid pressure streams to the other two. The latter amplifiers have substantially identical geometries and complementary gain curves at any given ... | 07/07/1987 |
| 4501293 | Gas flow responsive signal output means Signal output means (11) responsive to gas flow and particularly suited for use in gas flow indicator apparatus (10), has first and second pressure-datum valves (24, 25) arranged in downstream order in a gas conduit (16), the second pressure-datum valve (... | 02/26/1985 |
| 4258753 | Fluidic switch A fluidic amplifier or switch for supplying pulses of a power gas to be controlled which is insensitive to load impedance or back pressure. One arm of the fluidic switch comprising part of the gas injection path is coupled to a working outlet and the othe... | 03/31/1981 |
| 3958412 | Fluidic gas turbine fuel control A pure fluidic fuel control system for a gas turbine engine in which engine speed and compressor discharge pressure are sensed and utilized to control the flow of fuel to the engine. In the system an analog fluid signal proportional to engine speed is app... | 05/25/1976 |
