  • Sorting system with multi-plexer
    Patent number: 6497324
    Abstract: A system for sorting articles includes a feed conveyor for launching the articles across an airspace toward a first destination. A light source shines light energy on the articles in the airspace. A collector collects light energy reflected from the articles. A deflector is provided for deflecting selected articles toward an alternative destination as the articles fly across the airspace. A control system is operably connected to the collector and the deflector for actuating the deflector in response to a sensed parameter, such as an electromagnetic radiation frequency spectrum, of the light energy collected in the collector. Preferably, this system is utilized with a retro-reflector located on an opposite side of the airspace from the light source and the collector. This system also preferably includes the use of a multi-plexer which allows a single analyzer unit to be utilized to analyze light signals from each of a large plurality of collector units of the collector.

  • Electromagnetic radiation absorbers and modulators comprising polyaniline
    Patent number: 5563182
    Abstract: A method of providing electronic shielding comprising providing a layer of a polyaniline composition on the object to be shielded, whereby the entrance and egress of electromagnetic radiation is prevented. Also presented herein is a method of changing the absorption by a polyaniline composition of electromagnetic radiation by modifying the chemical structure and crystallinographic order of the polyaniline composition, wherein said composition comprises a composition of the formula ##STR1## where y can be equal to or greater than zero, and R.sup.1 and R.sup.2 are independently selected from the group consisting of --H, --OCH.sub.3, --F, --Cl, --Br, --I, --NR.sup.3.sub.2, --NHCOR.sup.3, --OH, --O, --SR.sup.3, --OR.sup.3, --OCOR.sup.3, --NO.sub.2, --COOH, --COOR.sup.3, --R.sup.3 SO.sub.3 H, --COR.sup.3, --CHO, and --CN, where R.sup.3 is a C.sub.1 to C.sub.8 alkyl, aryl, or aralkyl group.

  • Electromagnetic radiation absorbers and modulators comprising polyaniline
    Patent number: 5294694
    Abstract: A method is provided for absorbing electromagnetic radiation using a polyaniline composition, wherein the radiation is infrared, visible light, ultraviolet, radar, or microwave radiation. Also provided is a method for reducing the detectability by radar of an object by increasing the absorption of radar waves and thereby decrease the reflection of the radar waves by applying to the object a polyaniline composition or a partially protonated salt thereof.
