An airbag deployment sensor stores a quantity of tape which is drawn out of a cartridge during airbag deployment by one end of the tape which is attached to the inside surface of an airbag. The controller includes a first comparator comparing a voltage proportional to the power supply voltage with a reference voltage and activating the reset signal when the voltage proportional to the power supply voltage is less than the reference voltage. The glitch detect filter system provides a fixed output signal. The first entity has first policy data corresponding thereto and the second entity has second policy data corresponding thereto. A lower layer pattern contains a surfactant that is lyophilic with respect to droplets that form an upper layer pattern.
