Abstract: The present invention is a radio-controlled (RC) model aircraft system with laser tag capabilities. A transmitter and receiver are each installed in at least two separate RC aircrafts. The transmitter on one aircraft emits an infrared light beam to the receiver on the other aircraft(s) that changes the infrared signal to a first servo to move an arm, which releases a model aircraft door behind which there are ribbons. The ribbons escape from the aircraft wings to show a hit. An optional second servo operate a smoke screen and eject a pilot to simulate actual combat. The system may also include audio and lighting effects to simulate firing and hit sequences with accompanying theatrical, physical effects including release of smoke and ribbons, and ejection of the pilot that realistically simulates air combat.
Abstract: A method for fabricating field emission arrays employs a single mask to define emitter tips, their corresponding resistors, and, optionally, conductive lines. One or more material layers from which the emitter tips and resistors will be defined are formed over and laterally adjacent substantially parallel conductive lines. The exposed surface of the layer or layers of emitter tip and resistor material or materials may be planarized. The emitter tips and underlying resistors are then defined. Substantially longitudinal center portions of the conductive lines may be exposed between adjacent lines of emitter tips, with at least a lateral edge portion of each conductive line being shielded by material that remains following the formation of the emitter tips and resistors. The exposed portions of the conductive lines may be removed in order to define conductive traces. Field emission arrays and display devices fabricated by such methods are also disclosed.
Abstract: A rocket (100) is disclosed having a body (101) with a bay (102) therein and a latchable hatch (109) which is movable between a bay opened position and a bay closed position by a spring biased hinge (110). A parachute (117) is mounted to the hatch. Upon unlatching the hatch, the drag upon the hatch causes it to move reward thereby pulling the parachute from the bay for deployment.

Abstract: A rocket (100) is disclosed having a body (101) with a bay (102) therein and a hatch (109) which is movable between a bay opened position and a bay closed position by a spring biased hinge (110). The hatch is pivotally coupled to a nose section (104) by a spring biased hinge (11). The hatch is configured to be engaged and disengaged with a catch (118) mounted to the rocket body. With the initial forward movement of the launched rocket the inertia and/or the force of the wind upon the nose section causes the disengagement of the catch whereby the continued movement of the rocket creates a wind upon the nose section which maintains the hatch in its bay closed position.

Abstract: A toy aircraft glider for launching by a slingshot, having two-axis wing retraction for improved launch height and wing stability, internally-mounted wing deployment springs for improved toy life, the ability to eject smaller toys while airborne to enhance toy enjoyment, sound effects and remote control steering.
Abstract: A parachute for a powered model airplane in which the parachute is ejected downwardly by an ejection cartridge which may be installed for ejection of the parachute after the parachute is packed into its container in the airplane, and just prior to the take off of the airplane.
