1. Abstract
The Montage Object Detection Sensor is a stand-alone Time of Flight Volumetric Sensor with advanced hardware and firmware features. It is designed around an advanced Time of Flight imager chip. The system detects the presence or absence of cargo inside a container or a trailer and communicates data collected to a gateway over Bluetooth. It is mounted on the inside ceiling of a trailer and powered from an external 12VDC power source. By looking down from the ceiling, it senses the presence of cargo on the floor of the trailer.

FCC Regulations This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: –Reorient or relocate the receiving antenna. –Increase the separation between the equipment and receiver. –Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. –Consult the dealer or an experienced radio/ TV technician for help. Changes or modifications not expressly approved by the manufacturer could void the user’s authority to operate the equipment.
