Abstract: Systems and methods can control refrigeration within a refrigerated freight container. Thermal sensor nodes can be positioned within the freight container. Temperature measurements can be wirelessly relayed from the sensor nodes to a gateway associated with the freight container. The received temperature measurements can be aggregated and logged at the gateway. Thermal models of the freight container and associated cargo loads can be established in response to the logged temperature measurements and loading plan for the foreign container. The refrigeration system can be controlled in response to processing the thermal models. The refrigeration system can be controlled to optimize compliance parameters associated with the cargo loads.

Abstract: Systems and methods can secure freight container seals using electronic sensors. A hardened sensor clamp housing can include one or more sensing portals. The sensor clamp housing can receive a bolt seal through each of the sensing portals. One or more seal sensors may be positioned proximate to the sensing portals to sense a physical characteristic of the inserted bolt seal. This characteristic may be electrical, optical, magnetic, or so forth. The seal sensors can generate an electrical signal associated with cutting or tampering with the inserted bolt seal. The electrical signal can be coupled to a sensor clamp module operable to determine a tamper state of the bolt seal in response to the associated electrical signal. The determined tamper state can be communicated via a sensor clamp wireless module to a container controller or communications gateway.
