A multi-function sensor is disclosed which provides a reliable and simple device for accurately measuring andor monitoring the ambient conditions within a container or the like, such as the level of a fluid, the turbidity of a fluid, the temperature of a fluid or surrounding environment and the ambient pressure. In this case, an clipping reference position P corresponding to the imaging object in the imaging area image is determined, and a reference distance r between an imaging reference position O corresponding to the imaging unit and the clipping reference position P in the imaging area image is calculated. In an embodiment, one electrode of the electrode pair is separated from the other electrode of the electrode pair by a horizontal, vertical, depth, andor total distance of about 1 microns. The housing is connected to the underside of a roof vent. The control modifying section is configured to detect a change of the vehicle traveling direction in accordance with a second parameter which is the actual transmission ratio, and to modify the shift control of the toroidal continuously-variable transmission so as to shift the actual transmission ratio to a speed decreasing side upon detection of the change of the vehicle traveling direction. and 1 MHz in a matrix resin, and the insulator is substantially homogeneous in the dielectric constant throughout the insulator.
