First Claim
Patent Images
1. An apparatus for detecting an object in a cargo trailer comprising:
- a sensor mounted along a first wall of the trailer, the sensor having a pair of ultrasonic transducers having multiple operation modes with different ranges, with at least one operation mode scanning an area of the cargo trailer adjacent a distal end of the trailer from the first wall on which the sensor is mounted;
a trailer tracking control unit connected to the sensor, the control unit controlling the sensor and receiving data from the sensor; and
a power source electrically connected to the sensor.

23. An apparatus for detecting an object in a cargo trailer comprising:
-
a sensor mounted along a first wall of the cargo trailer, the sensor comprising a first ultrasonic transducer operating in a long range mode that scans out to an area adjacent a second wall, of the trailer, a rear wall being opposite and distal of the first wall, and a second ultrasonic transducer adapted to operate in a short range mode and in a proximity mode; a control module for controlling operation of the sensor; and a power source electrically connected to the sensor and the control module. - View Dependent Claims (24, 25, 26, 27)
