Abstract

A cargo restraint component such as a cargo restraint panel or a component of a load restraint strip system (e.g., a connecting strip or a load restraint strip) may comprise an attached RF beacon. That beacon can be configured to transmit identifying data. An RF beacon attached to a cargo restraint panel or to a component of a load restraint strip system may include one or more sensors that can measure one or more environmental parameters.

Claims

1. A method comprising:

placing a plurality of cargo units into a shipping container; and

placing a plurality cargo restraint panels in the shipping container,

wherein, after placement of the cargo units and the cargo restraint panels in the shipping container, the cargo units and the cargo restraint panels are arranged, in a front to rear direction of the shipping container, in alternating groups of one or more cargo units separated by one or more cargo restraint panels, with each of the cargo restraint panels being placed between, and separating, two of the cargo units,

wherein each of the cargo restraint panels comprises a foam component having at least one polymer foam sheet,

wherein each of the cargo restraint panels comprises an attached radio frequency (RF) beacon, and

wherein each of the attached RF beacons comprises a sensor configured to measure acceleration, a processor, an RF transmitter, and memory storing machine executable instructions that, when executed by the processor, cause the processor to perform steps that comprise

repeatedly transmitting, using the RF transmitter, one or more identification codes without an indication of acceleration outside of a threshold range,

monitoring values for acceleration measured by the sensor,

determining, based on the monitored values, acceleration outside of the threshold range, and

transmitting, in response to the determining, using the RF transmitter, and with the one or more identification codes, data indicative of the acceleration outside of the threshold range.

2. The method of claim 1, wherein the shipping container is a railcar.

3. The method of claim 1, wherein each of the attached RF beacons comprises a battery.

4. The method of claim 1, wherein the shipping container is a railcar,

wherein the foam component of each of the cargo restraint panels includes a foam component front face, a foam component rear face, and a plurality of foam component side faces, the foam component side faces located between the foam component front face and the foam component rear face, and

wherein, as to each of the cargo restraint panels, the RF beacon is located in a pocket extending from one of the foam component side faces and partially into the at least one polymer foam sheet.

5. The method of claim 1, wherein each of the cargo restraint panels comprises a front face reinforcing material bonded to and substantially covering a front face of the foam component, and

wherein each of the cargo restraint panels comprises a rear face reinforcing material bonded to and substantially covering a rear face of the foam component.

6. The method of claim 1, wherein, after placement of the cargo units and the cargo restraint panels in the shipping container, all of the cargo units are secured in the front to rear direction by one of another of the cargo units or one of the cargo restraint panels.

7. The method of claim 1, wherein, after placement of the cargo units and the cargo restraint panels in the shipping container, each of the cargo restraint panels is partially compressed.

8. A cargo restraint panel comprising:

a foam component having at least one polymer foam sheet;

a facing material bonded to and substantially covering a front face of the foam component and a rear face of the foam component; and

an attached radio frequency (RF) beacon, wherein the attached RF beacon comprises a processor, an RF transmitter, a sensor configured to measure acceleration, and memory storing machine executable instructions that, when executed by the processor, cause the processor to perform steps that comprise

repeatedly transmitting, using the RF transmitter, one or more identification codes without an indication of acceleration outside of a threshold range,

monitoring values for acceleration measured by the sensor,

determining, based on the monitored values, acceleration outside of the threshold range, and

transmitting, in response to the determining, using the RF transmitter, and with the one or more identification codes, data indicative of the acceleration outside of the threshold range.

9. The cargo restraint panel of claim 8, wherein the foam component comprises a foam component front face, a foam component rear face, and a plurality of foam component side faces,

wherein the foam component side faces are located between the foam component front face and the foam component rear face, and

wherein the RF beacon is located in a pocket extending from one of the foam component side faces and partially into the at least one polymer foam sheet.

10. The cargo restraint panel of claim 8, wherein the attached RF beacon comprises a battery.
