Abstract: A smart patch including multi-component strands integrated into clothing or other textiles where the strands of the smart patch include sensory elements that can simultaneously measure tactile forces, moisture/wetness, and other signals, such as biopotentials. A sensing system comprising: a first set of strands including a plurality of first multi-component strands, each of the first multi-component strands including a conductive portion and a non-conductive portion; and a second set of strands including a plurality of second multi-component strands, each of the second multicomponent strands including a conductive portion and a non-conductive portion, and a plurality of third multi-component strands, each of the third multicomponent strands including a conductive portion and a non-conductive portion, the third multi-component strands being different than the first multi-component strands and the second multi-component strands.

Abstract: A chemical and biological agent sensor includes an electrostatic thin film supported by a substrate. The film includes an electrostatic charged surface to attract predetermined biological and chemical agents of interest. A charge collector associated with said electrostatic thin film collects charge associated with surface defects in the electrostatic film induced by the predetermined biological and chemical agents of interest. A preferred sensing system includes a charge based deep level transient spectroscopy system to read out charges from the film and match responses to data sets regarding the agents of interest. A method for sensing biological and chemical agents includes providing a thin sensing film having a predetermined electrostatic charge. The film is exposed to an environment suspected of containing the biological and chemical agents. Quantum surface effects on the film are measured.

Abstract: Methods and systems for selectively connecting and disconnecting conductors in a fabric are disclosed. First and second conductors are integrated into a fabric such that the conductors intersect at a crossover point. The conductors are bonded to each other at the crossover point to improve AC and DC characteristics. Disconnect areas may be provided near the crossover point to allow selective disconnection of the conductors from the crossover point.

Abstract: Perlite, particularly, perlite in powdered form, is employed to adsorb metals and metal compounds from a fluid flow. In select embodiments, the perlite is treated to expand its surface area and injected into a fluid stream, such as flue gas, held for a specific retention period, and removed for subsequent disposal. In other embodiments the perlite is provided in a fixed adsorption bed and the fluid flow permitted to pass through the bed until the perlite surface is exhausted. The perlite in the fixed bed is then replaced, with the exhausted perlite disposed of as appropriate. Treatment of perlite by boiling with sulfuric acid or suspending in a suspension of sulfur in carbon disulfide has been shown to significantly expand the surface area of perlite.

Abstract: An adsorbent for HC in an exhaust gas is an agglomerate of double-structure particles, each of which includes an HC-adsorbing zeolite core, and a ceramic coat wrapping the zeolite core and having a plurality of through-pores communicating with a plurality of pores in the zeolite core. Each of the double-structure particles is at least one of a double-structure particle including the zeolite core comprising a single zeolite particle, and a double-structure particle including the zeolite core comprising a plurality of zeolite particles. Each of the through-pores in the ceramic coat has such a shape that the HC is easy to flow into the through-pore and difficult to flow out of the through-pore.
