摘要： A wipe sampling assembly used for an ion mobility spectrometer is disclosed. The wipe sampling assembly comprises three layers in which the upper layer and the lower layer are protective paper sheets, while the middle layer is a sampling swab. The swab will not be contaminated when not in use as it is covered by the two protective paper sheets. The hand can only contact the protective paper and will not contact the swab while sampling to prevent the swab from being contaminated. The above wipe sampling assembly is used with no need for any additional device, thus making it easy to operate and carry.

摘要： A method and apparatus for creating a bivariate histogram with a plurality of variables using impulse noise data is disclosed. The bivariate histogram describes the joint statistics between at least two of the variables. Also disclosed is an impulse noise monitor (INM) in communication with an impulse noise sensor (INS). The INM receives error data from the INS and creates a bivariate histogram with a plurality of variables using the error data. Included is a method for providing a bivariate histogram with an impulse noise length (IL) and an impulse noise inter-arrival time (IAT) for a plurality of impulse noise events. The IL and the IAT are each measured in integer multiples of discrete multi-tone symbols, and the bivariate histogram is used to determine a minimum impulse noise protection.
