Abstract: Deployed equipment modules for satellite architecture improvement (DEMSAI) provide ample thermal radiator for area-limited small satellites that typically deploy large-area solar panels from a relatively small mainbody. Rectangular-box-shaped equipment modules are deployed from a compact stowed assembly to offer each of their six side panel exteriors as potential radiator area. Equipment packages are mounted to the interior of these panels. The resultant increase in radiator area translates to an increase in the power-handling capacity of small, fixed-body satellites without resort to deployed radiators.

Abstract: A mechanical actuating device for moving an aerodynamic or hydrodynamic surface includes at least one flexure member confined in an elastically deformed condition. The flexure member is movable against the force generated by its elastic deformation to move the device into one of a plurality of stable positions, in which the device, and therefore the aerodynamic or hydrodynamic surface, are held by the force generated by elastic deformation of the flexure member. Since the flexure member is always elastically deformed, it “snaps” between discrete, stable positions and is held firmly in each. In another embodiment more flexure members can be used to provide additional stable positions. In one application, the actuating device is used as a trailing edge tab for a helicopter or tiltrotor blade to reduce 1/rev vibrations. The device can be actuated manually or electrically using shape-memory alloy wires to snap the flexure members into their various stable positions.

Abstract: New techniques are presented for detection methods employed in the control, automation and operation of scale Model railroad layouts that permit new types of capabilities to be incorporated into the railroad. The invention allows reliable detection of transponder devices on a model railroad layout using conveniently low values of transponder current pulses. Processing of the detected current pulse timing and direction characteristics and then comparing these with the expected or reference current direction for the layout section allows us to reject echo pulses caused by common impedances in the layout wiring. This method overcomes the pulse echoes that have caused the failure of previous attempts to reduce this technology to practice. Allowing additional acknowledgment pulses synchronized to any transponder address sent can further enhance Transponding technology. This provides extra communication capabilities that are not limited by the rate or timing of addresses sent to any particular transponder device.

Abstract: An electrically controlled proportional valve provides for precise control of fluid flow using an armature which is positioned at the center of a spider. The armature is supported and biased axially by a plurality of springs that radiate outwardly from it. The springs support the armature for elastic movement in the axial direction, and hold it biased against a first port, so that the armature functions as a valve element, which normally closes that port. A magnet coil is positioned so that when energized it applies force to the armature, overcoming the bias of the springs and drawing the armature away from the first port. During armature movement the plurality of springs are deflected at their outer diameter against an angled surface on the valve case. The increased spring surface area that rests against the valve case causes a proportional relationship between the movement of the armature and the magnetic field created by the magnet coil.
