Embodiments of the invention relate generally to power management and the like, and more particularly, to an apparatus, a system, a method, and a computer-readable medium for providing power controlling functionality to generate configurable power signals and to deliver power during fault conditions. The mobile terminal is portable and typically includes a central control unit, a gas detection unit, a warning unit and a user interface unit. The abstract syntax tree is indexed using a search structure defining all source code features for which searching is enabled. Typically, the obfuscation results in a different instance of the obfuscated code for each intended installation but each instance being semantically equivalent to the others. The handset is equipped with a space designed to hold a hand-held cordless telephone that can be removed from the handset, and for electrical coupling of the cordless telephone. The shoulder section is disposed between the body section and the neck section.
