Title: Apparatus and method for calibrating an acoustic detection system
Inventor: SMITH RICHARD A
IPC: G08B29/20
Filed: 2008-08-29
Abstract: A system and method for calibrating an acoustic detector. The method includes the steps of simultaneously transmitting an acoustic signal and an electromagnetic signal to an acoustic detector, receiving both signals, calculating a timing difference between the reception of the acoustic signal and electromagnetic signal, and setting a first time threshold used to determine if a glass panel is broken using the calculated difference and storing the first time threshold. A sensitivity level is also set based upon the determined timing difference. A unique key signature in the acoustic signal and electromagnetic signal is detected and matched with a stored signature to determine whether the signals are from a calibration signal. The timing difference is only calculated if both signals are calibration signals.

Abstract: Polyamidoamine (PAE) resins are prepared from polyamidoamine made with excess amine, which are reacted with a specifically defined amount of difunctional crosslinker. The amount of difunctional crosslinker used is based on the polyamidoamine amine number and reduced specific viscosity (RSV). The PAE resin is prepared by first synthesizing a polyamidoamine from a polyamine and a polycarboxylic acid or polycarboxylic acid derivative, wherein the polyamine is present in a molar excess, said molar excess being from about 1.02 to 2.00, then reacting the polyamidoamine with difunctional crosslinker, wherein the weight % of difunctional crosslinker to polyamidoamine solids is no more than about 0.308(amine number/RSV) - 9.18 or 0,385(amine number/RSV) - 5.20, wherein the amine number is expressed as the milliequivalents of amine per gram of polyamidoamine solids and the RSV is the reduced specific viscosity measured at 2 % concentration in IM NH4Cl expressed in deciliters per gram. PAE resins prepared according to this process can by used in creping adhesives, which are used to manufacture a variety of paper articles, such as facial tissue, bath tissue, wipes, paper towels, paper napkins, filter papers, and coffee filters.
