In a body frame structure for an automotive vehicle, the amount of the bending and deforming of a longitudinal frame member in the rear direction can be controlled and the amount of the collision energy absorption during a frontal collision can be increased. Specifically, a fuel tank sight glass in which a sight glass cleaner element travels to remove deposition material from the surface of the surface of a sight glass. Excess second material is then removed from the surface of the first material, leaving the coil of second material in the groove. The vibration sensor senses machine vibration along multiple machine axes when the apparatus is in sensory contact with the machine, and the conditioning circuitry optimizes the frequency response of the vibration sensor by reducing the gain of the sensor output at resonance. In conjunction with this, a disabled state is maintained for the input termination pull-ups of the memory device except when data is being received from the bi-directional single-ended data bus by the memory device. The control system can also adjust the level of illumination based on the signals from a motion detector, where the lights are set at a higher brightness for a predetermined amount of time upon detection of motion.
