A system to detect and avoid spilled cargo in an automobile vehicle, includes an automobile vehicle rear cargo area including a floor to temporarily receive a storage item in the cargo area. A lift gate is moved between a closed and latched position and a fully open position inclusive to allow loading and removal of the storage item. A vision system identifies the storage item when initially loaded in the cargo area and identifies if the storage item is initially positioned in a cargo spill position or subsequently moves to the cargo spill position. A cargo stop device is releasably connected to the lift gate. An operating system releasably stores the cargo stop device when the storage item is not in the cargo spill position and deploys the cargo stop device when the storage item is in the cargo spill position.

A fluid bypass valve includes a valve member disposed within a valve chamber of a housing. A temperature based actuating mechanism moves the valve member between a first position and a second position in response to a temperature change. A temporary flow control device undergoes a one-time only shape change between a first shape and a second shape. The temporary flow control device enables fluid communication between a first port and a second port when exhibiting the first shape, and does not enable fluid communication between the first port and the second port when exhibiting the second shape. The temporary flow control device exhibits the first shape when having an initial temperature less than or equal to a second pre-defined temperature, and exhibits the second shape in response to a first heating of the temporary flow control device to a temperature that is greater than the second pre-defined temperature.

A method of testing a SMA element includes connecting the SMA element to a validation tool, and applying an electrical current to the SMA element over a test cycle. A resistance of the SMA element during the test cycle is measured, while the electrical current is being applied. The measured resistance of the SMA element during the test cycle is correlated to an estimated strain value of the SMA element during the test cycle. A temperature of the SMA element during the test cycle is estimated. A stress in the SMA element during the test cycle is estimated from a stress predicting grid, using the estimated strain value and the estimated temperature of the SMA element during the test cycle. The proper functionality of the SMA element may be determined based on the estimated stress in the SMA element.
