In certain embodiments, a packaged terminal device for killing pests in an affected area includes a housing configured to be positioned at least partially within an affected area, a fan positioned within the housing, and one or more heating elements positioned within the housing. The present method uses both content and connectivity analysis. An annular gap is defined between the nozzle and the socket when the nozzle is received in the socket. The barrel is driven by a stepper motor to rotate a specific distance about a central axis. The micro-wire extends continuously from the first micro-channel side, over the micro-channel bottom, the rib side and rib top, to the second micro-channel side forming a continuous electrical conductor from the first micro-channel side to the second micro-channel side. The method includes the step of coating the solution of the dye compound on a substrate: where R1 and R2 may be identical or different from each other and each represents, respectively, a linear alkyl group or a branched alkyl group, the dye thin film having high thermal stability, having intense absorption at approximately 1.
