An article is coasted by preparing a coating source having an aluminum halide, a fluoride or an iodide of a modifying element as a source of the modifying element, and a carrier gas. The first switch control circuit controls the multiple stages of shift register units to turn on in a forward sequence; the second switch control circuit controls the multiple stages of shift register units to turn on in a backward sequence. The circuit includes a second row of circuit blocks that are each connected to ground directly and to the supply via a second sleep transistor. The apertures may includes an extended side opening that opens onto an upper surface of the housing to enable a contact beam and shielding bar to be inserted from the top. The method includes surveiling the main cabin of an aircraft, monitoring radio frequencies predesignated for handheld radio devices for signals, recording the generated images and monitored sounds on non-volatile media, and generating an alert in response to a threat perceived while surveiling and monitoring. The PVR extensions and PVR APIs may be configured to provide a seamless integration of functionality associated with the PVR-compliant device and the PVR device.
