An apparatus and method of processing signals from a passive infrared sensor evaluates energy of received signals. A center housing is connected to the turbine housing, and a compressor housing is attached to the center housing. Furthermore, a circuit 170 is created which prevents the program code being carelessly rewritten due to thermal runaway, a bug, and the like of a processor 211, and the protection setting by the protection logic 71 in the circuit 170 is released only in case the processor 211 accesses each of a plurality of registers from 65 to 67 in specified order. A priority for each item in the news corpus is determined based on the media type of the item, the corresponding statistical parameters for the media type of the item, and the profile of a user. The interactive map may be configured to help end users discover and share information associated with a plurality of venues. The transmitter apparatus may employ an FET-driven capacitive tuning circuit and a coil design that achieves high precision, high-quality transmission signals, and which may be equipped with a high-voltage booster for facilitating fault-localization applications.
