Active logistical tag for cargo
First Claim
Patent Images
1. An active logistical tag for cooperation with a pallet, said tag comprising:
- a housing configured to fit within a slot in an outer rail of the pallet;
a sensor section within the housing, the sensor section comprising;
an electromagnetic radiation sensor comprising an amplifier and adapted to sense logistical prompts due to incident electromagnetic radiation;
a motion sensor adapted to sense logistical prompts due to motion of the tag; and
a static magnetic field sensor adapted to sense logistical prompts due to the tag being within a static magnetic field generated external to the pallet;
a transmitter section within the housing the transmitter section adapted to transmit logistical information to a reader; and
a controller within the housing, the controller in communication with the sensor section and the transmitter section, the controller configured to cause the transmitter section to transmit beacon signals in response to sensing, by the static magnetic field sensor, whether or not the tag is within external static magnetic field.
