Abstract: A system including a motorized base unit with a smart device mount for automatically orienting the smart device camera toward a moving target to track the moving target and take pictures or video. The target (e.g., a child playing soccer) wears a tracking tag comprising a GPS chip and transmitter packaged inside an athletic pad. The base unit includes a motorized mast for mounting a smart device. The base unit receives the transmitted GPS data, calculates updated pointing angle and angular velocity for the smart phone based on update location information from the remote tag sensor, calculates the correct angle that the smart phone should be pointed at, translates the new pointing directions to a control signal that turns the mast, which in turn causes the smart device camera to “follow” or track the target.

Abstract: A tool for installing and/or removing covers for light bulbs within a fixture is described. The tool may have a tube-shaped body with an installation end, a removal end, and a central axis along the tube-shaped body. A platform may be located within the tube-shaped body near the installation end. One or more frictional elements on an interior surface of the removal end may engage the cover. A handle attachment may be selectably and rotatably coupled to an exterior of the tube-shaped body between the installation end and the removal end.

Abstract: An aircraft includes an airframe, an extending tail, a counter rotating, coaxial main rotor assembly including an upper rotor assembly and a lower rotor assembly, and a translational thrust system positioned at the extending tail. The translational thrust system provides translational thrust to the airframe. An upper hub fairing is positioned at the upper rotor assembly. A lower hub fairing is positioned at the lower rotor assembly. A shaft fairing is disposed between the upper hub fairing and the lower hub fairing. The upper hub fairing is substantially sealed to the shaft fairing and the lower hub fairing is substantially sealed to the shaft fairing.

Abstract: A radiator bracket connects a radiator to a support surface, such as a wall, and includes at least one vertically extending channel having a width that decreases from an open end to a narrow end with the narrow end being located closer to either the radiator or the support surface. The vertically extending channel can be a single channel or two channels. Where the bracket has a single channel, two brackets can be used with one of the brackets having its narrow end closest to the radiator and the other having its narrow end closest to the wall.

Abstract: An aircraft includes an airframe; an extending tail; a counter rotating, coaxial main rotor assembly including an upper rotor assembly and a lower rotor assembly; a translational thrust system positioned at the extending tail, the translational thrust system providing translational thrust to the airframe; an upper hub fairing positioned at the upper rotor assembly; a lower hub fairing positioned at the lower rotor assembly; and a shaft fairing disposed between the upper hub fairing and the lower hub fairing; wherein a geometry of at least one of the upper hub fairing and the lower hub fairing progressively blends from a circle to a series of curved elliptical surfaces in an inboard direction.

Abstract: A lined conduit formed by decorrugating a corrugated liner conduit inside a first conduit is described. A method and apparatus for forming the lined conduit are also described. The corrugated liner conduit may be positioned inside the first conduit. Each end portion of the corrugated liner conduit may be coupled to a hydraulic expander. Each hydraulic expander may include a hydraulic cylinder. Each hydraulic cylinder may include a piston rod with an opening along the length of the piston rod. The corrugated liner conduit may be evacuated through a valve assembly coupled to the passageway in one of the piston rods. The evacuated corrugated liner conduit may be pressurized with fluid from a fluid source coupled to the valve assembly. Pressurizing the corrugated liner conduit may expand corrugations in the corrugated liner conduit to form a decorrugated liner in the first conduit.

Abstract: A utility conservation system and method uses a system controller to detect an access device entering or leaving a building area. A wireless transmission corresponding to the detection is received by one or more interruption devices that connect or remove an electrical load from an electrical supply for conservation when the building area is unoccupied.

Abstract: A conduit modifier may be used to corrugate at least a portion of a conduit. The conduit modifier may include at least a first plurality of rollers arranged in a first pattern around a passageway. The first plurality of rollers may form ridges and grooves lengthwise along a conduit passing through the passageway. A second plurality of rollers arranged in a second pattern around the passageway may compress ridges formed by the first set of rollers. The ridges may be formed such that a distance from a central axis of the conduit to a highest portion of an outer surface of a ridge is substantially equal to a distance from the central axis of the conduit to an outer surface of the un-corrugated portion of the conduit. The corrugated portion of the modified conduit may be expandable.

Abstract: A pressure sensor is arranged to sense the pressure of a pressurized welding gas and produce a variable control output dependent upon the pressure level sensed. A control signal is initiated in response to pressure of a predetermined level being sensed, the control signal being passed to the welding apparatus driver circuitry to inhibit the welding operation.

Abstract: An interactive light display includes multiple LED's selectively arranged to provide a light display, each of the LED's being capable of a plurality of activation states. Multiple fiber optic strands are also included, each strand having one end near one of the LED's and extending away from the LED to carry light outward from the LED. A computer is used for controlling the activation state of each of the LED's, allowing a wide variety of routines to be run with the display. Standard computer cable is used for connecting each of the LED's to the controlling computer, such that the activations states of all the LED's may be controlled to form selected light patterns. At least one one-way hinge may be positioned on each branch of the tree such that the distal portion of the branch is capable of hinging only upwards relative to the branch.

Abstract: A detector system for providing a plurality of output beams for monitoring the output beam of a laser system. The detector system includes a refractive element having a pair of opposing spaced-apart faces. The laser beam enters the refractive element where it undergoes multiple internal reflections off of the faces. A portion of the beam is transmitted out of the refractive element at each of the reflections to form a plurality of increasingly attenuated output beams having different power intensities from each other. A plurality of detectors are positioned for measuring the different beam characteristics of the plurality of attenuated output beams, which correspond to the beam characteristics of the laser output beam.
