A PC-based ECG software program that in real time, acquires, analyzes and displays QTV and PQ interval variability in each of the independent channels that constitute the 12-lead conventional andor Frank X, Y, Z lead ECG. Interior and exterior antennas are respectively driven using first driving currents, the interior antenna being separated from the transponder by a portion of a vehicle in which the vehicle base station resides. The negative ion supplying unit is configured to discharge negatively ionized air toward the skin surface and includes a negative ion generator which is configured to generate the negatively ionized air. Sending the notification regarding the event includes sending the notification to the second party. Instructions from the instruction sequencer direct the integer ALU to perform integer operations according to logic states stored in the 1-bit ALU and data stored in the decision unit.
