Abstract: A low-cost airliner defense system utilizing self powered, retrievable, towed decoys against man portable heat-seeking missile (MANPAD) systems provides both high power and a large IR radiating surface area. An efficient and lightweight integrated turbine-alternator extracts sufficient electric power from an air stream directed through a small decoy deployed and towed behind an aircraft during the vulnerable phases of a flight to power a large and intense IR emitter. Unfurled IR radiator “petals” present large area arrays of rear-facing IR emitters. During the high-altitude cruise phase the radiating petals furl down folding around the retrieved decoy body as it is stowed in a streamlined housing for minimizing fuel consumption and maneuverability penalties.

Abstract: A method and an apparatus for measuring the pressure or other physical quantities of a gas or a liquid in a sealed container without penetrating the container. Two permanent magnets, one located on a sensing unit inside the container and one located on a readout unit located outside the container are used to communicate the magnitude of the pressure sensed inside the container to the readout unit. No power supply is required to implement this system.

Abstract: A method of marketing products and collecting polling information is disclosed. The method comprises putting an entire product on the Internet and rewarding users for using and/or interacting with the actual product and providing a rating for that product.

Abstract: A hybrid control system executes tasks within a transaction which is executed in a given order. The order in which the tasks are executed is inversely proportional to their deadlines. The deadlines are assigned an initial deadline D, an initial maximum end-to-end delay of the transaction is calculated using the initial deadlines D and the given order of the tasks.The deadline of the task with the largest deadline is reduced by an increment to give a new deadline and if the task following it has an increment to give a new deadline. A new end-to-end delay is calculated using the new deadlines and the given order of the tasks. These steps are repeated until the new end-to-end delay does not exceed the desired maximum end-to-end delay.

Abstract: An acoustic method and apparatus for measuring the horizontal surface location and depth of any type of underground pipe or conduit, including nonmetallic or nonconductive pipe, such as sewer, gas, and water pipes, which cannot be detected with electromagnetic locators. A continuous-wave (CW) acoustic signal is injected into and transmitted through the fluid (liquid or gas) in the pipe. The horizontal surface location and depth of the pipe are determined from an analysis of the phase measurements derived from an array of acoustic measurements, which are made at the surface and approximately perpendicular to the direction of the underground pipe.

Abstract: An apparatus for measuring liquid level in a container, the apparatus having a flexible measurement scale attached at one end to a weight for retainment at the bottom of the container and at the opposite end to a receiver at the top of the container. A float moves along the flexible scale, and has a configuration and density designed to place a portion of the float below the level of the liquid to be measured and a portion above the liquid level. The portion above the liquid level contains transmitter apparatus for applying energy to one side of the scale, and detection apparatus on the other side for detecting energy transmitted through the scale and converting it to a liquid level in the container.

Abstract: A hockey puck with an electromagnetic transmitter. The electromagnetic transmitter could include an infrared transmitter, ultraviolet transmitter, radar repeater, RF transmitter or other device for transmitting electromagnetic waves outside of the visible spectrum. The electromagnetic transmitter is turned on using a shock sensor and is turned off using a timer.
