A system for detecting and verifying an environmental anomaly within a shipping container (transported on a transit vehicle having an external transceiver) has wireless sensor-based ID nodes at different locations within the container and multiple command nodes mounted to the container. A first command node is programmatically configured to be operative to detect the sensor data broadcasted from the ID nodes; responsively identify the anomaly based upon the sensor data detected by that command node; and transmit a validation request to another command node. The other command node is configured to be operative to also detect the sensor data broadcasted from the ID nodes; receive the validation request from the first command node; verify the anomaly in response to the validation request and based upon the sensor data detected by the second command node; and broadcast a verification message based upon whether the anomaly for the shipping container is verified.

A fabric assembly and method of manufacturing a spliced liquid-mounted seal sheet is provided. The method includes overlapping a first fabric layer and a second fabric layer, wherein at least one of the first fabric layer or the second fabric layer defines an opening having a shaft defining a channel positioned therethrough, the shaft housing a valve having an open position and a closed position, wherein the valve is configured to allow a fluid through the channel in a first direction while the valve is in the open position, and the valve prevents the fluid through the channel while the valve is in the close position. The method further includes splicing the first fabric layer to the second fabric layer to form a spliced fabric composite comprising an interior pocket space defined by the first fabric layer and the second fabric layer.
