Abstract: A method of particle detection in an aspirated particle detection system having a sampling pipe network and a particle detector. The method includes drawing sample air to the particle detector through the air sampling network; analyzing the sample air with the particle detector; entering an amplification phase, in the event that a concentration of particles in the sample air greater than a predetermined threshold is detected, to create a plurality of sample air packets in the sampling pipe, wherein each sample air packet corresponds to a sampling inlet and includes an amplified concentration of air drawn from the corresponding sampling inlet; transporting the sample air including the plurality of sample air packets through the sampling pipe to the particle detector; and determining through which sampling inlet any particles entered the particle detection system.

Abstract: Polypyrrole/carbon (PPy/C) composite doped with organic anion p-toluenesulfonate (pTS) is utilized as an electrode in supercapacitor for energy storage application. The surface initiated in-situ chemical oxidative polymerization yields a composite material PPy/C in the presence of varying concentrations of pTS. The novelty of the present invention lies in the doping of PPy/C composite with organic anion pTS and consequent enhancement of its electrochemical activity and stability. The conjugation length and electrical conductivity of pTS doped PPy/C composites increase with the increase in dopant concentration. The pTS doped PPy/C composite synthesized using equimolar concentration (0.1 M) of pTS to pyrrole shows the maximum specific capacitance of ˜395 F/g in 0.5 M Na2SO4 aqueous solution with significant stability ˜95% capacitance retention after ˜500 cycles.

Abstract: A sensing system and method for detecting particles in an air volume includes a main airflow path including an inlet from the air volume. Also included is a collection site within the main airflow path. The collection site is for drawing an air sample from the main airflow path. Additionally the system includes a means to induce a localized increase in particle speed at the collection site relative to air speed along the remainder of the main airflow path. The means to induce a localized increase includes an auxiliary airflow path from the main airflow path. The auxiliary airflow path has an exit upstream of the collection site. In an alternative form of the invention, the means to induce the localized increase in particle speed at the collection site comprises a venturi in the main airflow path with the collection site being disposed along the venturi.
