Abstract: A flip placard includes a base, a hinge, a plurality of placards and two securing clips. The placards each have an aperture therein to be mountable about and movable relative to the hinge. Each placards has a first edge mountable to the hinge and a second edge having a variably located cutout portion defining a tab with indicia thereon. The securing clips have a first position engaging the second edge of the placards and a second position not engaging the second edge of the placards wherein each of the tabs are not viewable in the first position and are viewable in the second position.

Abstract: An optical and radio frequency (RF) antenna includes a substrate and a spiral pattern formed on and/or in the substrate from a metallic material. The spiral pattern has a central region and peripheral region surrounding the central region. The central region is configured to transmit and receive an optical signal at optical and/or infrared wavelengths and the peripheral region is configured to transmit and receive an RF signal at RF wavelengths. The central region and the peripheral region are configured such that an optical gain pattern of the central region and an RF gain pattern of the peripheral region are co-boresighted.

Abstract: A folded optical system includes a powered optical element, at least one folding mirror and an aperture and defines an optical path through the optical system. The powered optical element, the at least one folding mirror and the aperture are configured to fold the optical path at the aperture, thereby providing a compact optical system. The optical system may include an optical block that totally internally reflects the optical signal at the aperture. Optionally or alternatively, discrete optical components may be used, such as an aperture made of a conventional material or a metamaterial, an off-axis parabolic mirror or lens and one or more folding mirrors. Some embodiments include a wavelength dispersive element, so as to implement a spectrometer.

Abstract: A method and system for removing hydrocarbon deposits from a heat exchanger tube bundle using an organic solvent. After contact with a heat exchanger tube bundle, the contaminated organic solvent may be treated to remove solids, base waters, and/or suspended hydrocarbons, and then again contacted with a heat exchanger tube bundle for the removal of hydrocarbon deposits. This allows for the removal of hydrocarbon deposits from a heat exchanger tube bundle in an efficient and environmentally friendly manner. The treatment of the heat exchanger tube bundle is also preferably performed using a method and system by which, through contact of the heat exchanger tube bundle with an organic solvent, a large percentage of hydrocarbon deposits are removed from the heat exchanger tube bundle in a short period of time.

Abstract: The electronic communication system for a vehicle includes a processor, a memory, an audio output device, a power supply, and a controller. The electronic communication system for a vehicle is useful for storing and accessing sound files, which may include the brand name of an automobile, and emitting audible communications to the environment external to a vehicle.

Abstract: A dental handpiece may comprise a detachable light source assembly comprising a light source, a power source, and at least one switch, and the detachable light source assembly may be configured to be selectively removable from the handpiece.

Abstract: The present invention comprises a method and system for the in-situ cleaning of a heat exchanger tube bundle of carbonaceous deposits. Using the method and system, an organic solvent is brought into fluid communication with one or more heat exchanger tube bundles in a closed system. The closed system is formed at the site of operation of the heat exchanger tube bundles and without having to remove the heat exchanger tube bundles from their shells or other associated equipment. Once the closed system is formed, the organic solvent is brought to a temperature at which it is effective to remove carbonaceous deposits from the heat exchanger tube bundle and flowed through the equipment associated with the heat exchanger tube bundles so as to contact the heat exchanger tube bundles and remove carbonaceous deposits that have formed therein.

Abstract: A device and method for selectively illuminating and designating multiple targets in the air or on the ground simultaneously. The device comprises a light source, a switching array and a ball lens. Light from the light source is routed through the switching array, which can addressably output multiple light beams simultaneously. The light beams from the switching array illuminate the backside of a low F-number ball lens. The ball lens creates highly collimated output beams independently (and simultaneously) from any of the output source points of the switching array. These output beams can be used to simultaneously designate multiple targets. When the target illuminating device includes an optional detector array, light scattered from targets can be refracted by the balls lens to impinge on the detector array. Signals from the detector array representing the received light beams can be used for target imaging.
