Patent Images
1. A tractor-trailer arrangement, comprising:
- a trailer including;
at least one wall separating an interior of the trailer from an ambient environment;
a door disposed in one said wall, the door having an open position and a closed position;
a wireless door contact sensor configured to;
sense whether the door is in the open position or the closed position; and
transmit a sequence of long wave magnetic position signals, each of the position signals being indicative of whether the door is in the open position or the closed position at a respective point in time; and
a tractor unit mechanically coupled to the trailer, the tractor unit including;
at least one of an audio speaker and a video display; and
a controller configured to;
receive the long wave magnetic position signals from the sensor; and
control presentation of information on the at least one of an audio speaker and a video display dependent upon the received position signals.

Abstract
An automotive communication method includes installing a sensor within a vehicle such that the sensor is submerged in a liquid during operation of the vehicle and/or substantially surrounded by a metallic structure during operation of the vehicle. A long wave magnetic signal is transmitted from the sensor. The signal is indicative of a condition sensed by the sensor. The signal is wirelessly received at a controller disposed within the vehicle. Receipt of the signal at the controller is responded to by adjusting a display and/or a setting within the vehicle.
