...that Robert Adler has the dubious distinction of being the Father of the Couch Potato? Back in 1955 Adler was employed by what was then Zenith Radio Corp., where he was charged to invent something that would allow viewers to turn down the TV volume without leaving their chairs. After a series of flops (such as a wired contraption that people tripped over), Adler hit on the idea of using sound waves. Thus the Remote Control was born...

| 7424360 | Overspeed control system for gas turbine electric powerplant A turbine overspeed control system for use with a gas turbine engine of a gas turbine electrical powerplant. The overspeed control system preferably comprises a first and second overspeed control subsystem. When an overspeed condition of the gas turbine engine is de... | 09/09/2008 |
| 6487847 | Gas turbine engine fuel control system A fuel control system for an aircraft gas turbine engine that includes a thrust augmentation system. An augmentor fuel pump is arranged to provide pressurized fuel to an exhaust nozzle throat area actuation system to eliminate the need for a separate hydr... | 12/03/2002 |
| 6270037 | Rapid response attitude control logic for shaft-driven lift fan STOVL engine A short take-off and vertical landing ("STOVL") aircraft has a conventional gas turbine engine that is selectively mechanically connected to a vertically-oriented lift fan by a drive shaft when the aircraft operates in a vertical flight mode. An engine co... | 08/07/2001 |
| 6269627 | Rapid thrust response control logic for shaft-driven lift fan STOVL engine A short take-off and vertical landing ("STOVL") aircraft has a conventional gas turbine engine that is selectively mechanically connected to a vertically-oriented lift fan by a drive shaft when the aircraft operates in a vertical flight mode. An engine co... | 08/07/2001 |
| 6000215 | Method of operating a gas turbine engine The present invention provides a method of maintaining fan airflow at 100% for throttle transients from 100% military power to 30% thereof by increasing exhaust nozzle area as the fuel flow the engine decreases until the exhaust nozzle reaches its fully o... | 12/14/1999 |
| 5687564 | Low rotor vibration avoidance in aircraft gas turbine engines Corrected fan speed (N1C2) and engine pressure ratio (EPR) are controlled, by controlling exhaust nozzle area (EA) according to a schedule or map so that as altitude increases (P2 decreases) the axial forces on the low rotor are sufficient to minimize low... | 11/18/1997 |
| 5579635 | Distributed erosion region rocket motor nozzle A rocket motor nozzle has a nozzle core that defines a nozzle passage through which combustion products travel during flight. The erosive forces created by the combustion products are longitudinally distributed over the nozzle core so that the nozzle's sm... | 12/03/1996 |
| 4813226 | Demand control of variable geometry gas turbine power plant In a gas turbine power plant system having an engine of the variable geometry type, the variable geometry is controlled in response to an input demand speed signal rather than a signal representing actual engine speed. The geometry which may be varied may... | 03/21/1989 |
| 4809500 | Transient control system for gas turbine engine A secondary control for a gas turbine engine powering fighter class of aircraft serves to modify the primary control solely during transient engine operation primarily in the combat box of between approximately 0.4 to 1.2 Mach number at an altitude betwee... | 03/07/1989 |
| 4501117 | Device for controlling and regulating the cross section of a variable area propulsive nozzle Disclosed is an improved device to control and regulate the opening and closing of a cross section of a turbojet propulsive nozzle having at least one hydraulic cylinder acting on at least one movable flap element. The invention includes a first system to... | 02/26/1985 |
| 4397148 | Control system for an augmented turbofan engine The engine includes a main engine fuel flow, an augmentation fuel flow, and a variable area exhaust nozzle. Primary speed control means is powered by first electrical power supply means. Fan speed is controlled by modulation of main engine fuel flow. Loss... | 08/09/1983 |
