A container system is provided and includes a body having a first end, a second end opposite the first end, and a door disposed at the second end. The container system further includes a telematics device disposed at the first end and a door sensor disposed at the door and capable of low-power wireless communications with the telematics device.

A composite structure of a cargo body and a method of making the same are disclosed. The composite structure includes at least one anchor embedded between fiber-reinforced polymer (FRP) layers. The embedded anchor includes a porous veil of nonwoven fibers in a polymer-rich matrix. Accessories may be coupled to the composite structure by anchoring mechanical fasteners into the embedded anchor.

An insulating container comprises a container body and a container cover connected to the container body. The container body and the container cover each comprises a frame and a plate arranged on the frame. The plate comprises, from inside out, an external high strength sheet, an extruded polystyrene sheet, phase-change insulating sheets made of phase-change material, and an internal sheet. A phase-change process of the phase-change insulating sheets cooperates with a refrigeration system of the transportation device to precisely control the temperature of the insulating container and a refrigerator truck to be near a phase-change temperature. In the present disclosure, the phase-change insulating sheets made of the phase-change material remain to be in a solid state before or after occurrence of a phase change, so that the structure of the insulating container does not change with the phase change and a leakage problem of the phase-change material does not exist.

Disclosed is a gas detector system for a refrigerated interior volume of a transportation refrigeration unit (TRU), the system having: a gas detector that defines an enclosure, the enclosure defines a chamber therein, the cover including a chamber opening, and an infrared (IR) sensor within the chamber; and a heater adjacent to or within the enclosure, the heater configured to reduce moisture within the chamber and/or prevent moisture from accumulating from within the chamber during a refrigeration cycle.

Systems and methods directed to a solar electric system for use in freight systems. In some embodiments, a solar power system can be configured to provide power to a refrigerated truck trailer. For example, a solar power system can be composed of a solar panel package that can include solar cell layer(s), conductive material(s), and support portion(s).

A cargo vehicle is disclosed having a composite floor assembly with at least one embedded hardpoint connector. The composite floor assembly may comprise a plurality of transverse beams, wherein a subset of the plurality of transverse beams includes at least one embedded hardpoint connector. The embedded connector may be used to securely and removably couple other vehicle components to the composite floor assembly, such as a landing gear assembly and/or a slide rail assembly.

An inflatable insulation panel includes a bladder configured to contain air, plurality of tethers disposed within an interior cavity of the bladder, and at least one reflective film disposed within the interior cavity of the bladder. The bladder includes a first wall, a second wall opposite of the first wall, and perimeter walls extending between and connected to perimeter edges of the first and second walls. The first and second walls and the perimeter walls collectively defining the interior cavity of the bladder. The plurality of tethers extend between and are connected to interior surfaces of the first and second walls. The plurality of tethers limit movement of the first and second walls away from one another when the bladder is inflated. The at least one reflective film is disposed between the interior surfaces of the first and second walls.

Methods and systems for power management are provided. Aspects include receiving, by a controller, load data associated with two or more refrigeration systems, wherein the two or more refrigeration systems comprise at least a first refrigeration system and a second refrigeration system, determining, by the controller, an available power capacity for the first refrigeration system and the second refrigeration system, operating, by the controller, the first refrigeration system and the second refrigeration system in a plurality of modes based at least in part on the load data and the available power capacity, wherein the plurality of modes comprise an unloaded mode and a plurality of loaded modes.

A floor securing apparatus comprises a riser slot formed in a floor riser, extending from a top surface toward a bottom surface of the floor riser. The floor riser is configured to support a floor sheet. The apparatus further includes a key including a locking head and at least one anchor tab, where the key is slidable into the riser slot and configured to engage a portion of the floor sheet when slid into the riser slot to prevent vertical movement of the floor sheet relative to the floor riser.

A transportation refrigeration unit TRU (26) and power system. The TRU (26) and power system including a compressor (58) operatively coupled to an evaporator heat exchanger (76) and an evaporator fan (98) configured to flow a return airflow (134) over the evaporator (76). The system also includes a return air temperature RAT sensor (142) disposed in the return airflow (134) and configured measure the temperature thereof, a TRU controller (82) connected to the RAT sensor (142) that executes a process to determine an AC power requirement for the TRU (26) based on the RAT sensor (142); a generator power converter (164) configured to receive three phase AC power (163) from a three phase AC generator (162) and transmit a second DC power (165b) to an energy storage system (150); a power management system (124a) configured to receive three phase AC power (157) from at least the energy storage system (150) and generate a TRU DC power (129), and directing the TRU DC power (129) to the TRU system (26).
