Abstract: A one-piece molded plastic flashing precisely fits outside corners of chimneys, dormers and roof offsets on pitched roofs ranging from 3/12 to 12/12 consisting of a horizontal roof plane, and a pair of vertical planes, angled with respect to one another to match with the pitch of the roof.

Abstract: An amplifier redundancy system includes an amplifier receiving signals from a first input switch when the switch is in a side port position. The system further includes a first output switch, in a side port position, receiving signals from the amplifier. A second amplifier receives signals from the first input switch through a second input switch and generates amplified signals therefrom. The second input switch also receives signals from the first input switch when the first input switch is in the side port position. The first input switch is initially in the side port position but switches to a through port position in response to a failure in the second amplifier. A second output switch is in a through port position and switches to a side port position and receives signals through the first output switch in response to the failure in the second amplifier.

Abstract: A lightweight self-contained vibro-acoustic device is disclosed for dissipating low frequency vibration and acoustic energy within the payload fairing of launch vehicles. The device can be mounted on the interior surfaces of a fairing and adaptively tuned to match targeted structural and acoustic dynamics using electronic feedback loops.

Abstract: This invention presents a novel means to passively achieve a compact moving-coil actuator with a very low natural frequency. The diaphragm and voice coil are mounted in a sealed enclosure from which the air is partially or completely evacuated. This reduces the air spring effect. The diaphragm is supported by a non-linear, buckling, or collapsible support apparatus. By taking advantage of the non-linear stiffness properties of such structures, the stiffness of the actuator can be designed to be small at the operating point, which when combined with the moving mass, yields a low natural frequency.

Abstract: A printer is provided which has a special Emulation Manager function as well as a “code sniffer” function, in which print data received is sent to a code sniffer buffer. A code sniffer function automatically determines the type of emulator that should be called to perform the interpretation or rendering of this print job, and if the code sniffer determines that the correct emulator is PostScript, then the code sniffer scans the data for any “special tokens.” If a special token is found, the PostScript emulator determines if the special token string data is part of a PostScript comment. If it is in the correct format, then the PostScript emulator sets the “mode flag” to the “MacBinary” state, and the code sniffer ceases any further filtering of control characters and disables any change of emulator command that may be received during this print job.

Abstract: A virtual sky hook vibration isolation system provides reduction of transmissibility at resonance without significantly increasing high frequency transmissibility. Isolation is achieved passively and without the need for an inertial reference frame. Design of the primary and secondary suspension systems is performed concurrently to achieve the desired performance. The primary suspension affords the necessary static deflection properties and high frequency isolation. The secondary system couples to the system at resonance and provides damping to the dynamic response. This combination yields the isolation benefits of the skyhook damper concept. The penalty for this performance is the necessity of a secondary spring-mass-damper device. However, results indicated that good performance can be achieved using a relatively small secondary mass (5% of the primary mass).

Abstract: This invention presents a passive vibroacoustic device that serves the dual function of attenuating the vibration of a flexible structure, and providing acoustic dissipation to the volume or cavity enclosed by the structure. This reduces the transmission of sound from external sources into the enclosure, and reduces vibration of the structure. By design of the shunting resistor and the mass and suspension properties, the device can be optimized to achieve high levels of both structural vibration attenuation and acoustic attenuation. Incorporating a feedback loop or adaptation mechanism will permit the device to maintain optimum attenuation in the case of time varying systems.

Abstract: The vacuum floor brush cleaner is generally in the form of a rectangular three sided tray into which a vacuum cleaner brush attachment or floor cleaning unit may be placed or rolled. The bottom inside surface of the tray may have protrusions extending therefrom which engage the brush attachment bristles to remove dirt, hair, thread and other such accumulated debris. The tray may have an adjustable wire bar with protruding wire elements which can be raised and lowered depending on the vacuum cleaner brush attachment. In the case of rotating roller brush units used in floor cleaning units, the wire elements are of a length such that when the wire bar is at the appropriate height the wire elements engage the hard surface of the roller to remove entangled thread and other such debris. Rotating handles and gears as well as levers and gears or cams may be used to raise and lower the wire bar.
