Abstract
A system to capture data regarding conditions in a sealed metal shipping container having: a sensor unit mountable inside the container and adapted to sense a condition inside of the container; an impulse radio transmitter receiving data from the sensor regarding the condition and transmitting an impulse radio wireless signal inside of the container; an impulse radio receiver external to the container and proximate the container, wherein the receiver is adapted to receive the impulse radio wireless signal propagating through the sealed metal shipping container, and a data device in communication with the receiver to capture the data from the sensor unit regarding the condition inside of the container.
Claims17
A system to capture data regarding conditions in a sealed metal shipping container comprising:
- a sensor unit mountable inside the container and adapted to sense a condition inside of the container;
- an impulse radio transmitter receiving data from the sensor regarding the condition and transmitting an impulse radio wireless signal inside of the container, wherein said transmitter comprises an antenna mounted internally within the container;
- an impulse radio receiver external to the container and proximate the container, wherein said receiver is adapted to receive the impulse radio wireless signal from the antenna and said signal propagates through the sealed metal shipping container, and
- a data device in communication with the receiver to receive said signal and capture the data from the sensor unit regarding the condition inside of the container.
A method to capture data regarding at least one condition in a sealed metal shipping container comprising:
- mounting an wireless transmitter inside of the container;
- mounting a sensor inside of the container to monitor the at least one condition and establishing a communication link within the container between the transmitter and the sensor wherein the transmitter receives data from the sensor regarding the condition;
- sealing shut the container;
- transmitting an wireless signal carrying the data regarding the condition from the transmitter wherein the signal emanates from an antenna entirely inside of the sealed shut container, and propagates outside of the container;
- receiving the transmitted wireless signal by a receiver located externally of the container and proximate the container;
- and
- capturing the data from the wireless signal in a data device in communication with the receiver to store the captured data regarding the condition.
