“Embedded Software Build” is the process of taking all source code files that are part of the embedded system and compiling them into build artifacts, such as executables or binaries for the target embedded hardware. In the case of embedded systems, it includes low level software for a specific embedded hardware device, the application software and the associated application data. To further complicate this, low level software also known as firmware or middleware layers are often hand-coded while the application layer is auto-coded. To ensure build reproducibility, accurately predict build results and achieve error-free embedded software builds both in a lab environment and in the field, embedded software builds are required to be automated. At the very initial stage of the project, we realized that the automation of the Embedded Software Build is highly imperative and extremely crucial, as we're dealing with a Real Time - Safety Critical - Aerospace Embedded System.

The increasing usage of brake-by-wire systems in the automotive industry has provided manufacturers with the opportunity to improve both vehicle and manufacturing efficiency. The replacement of traditional mechanical and hydraulic control systems with electronic control devices presents different potential vehicle-level safety hazards than those presented by conventional braking systems. The proper design, development, and integration of a brake-by-wire control system requires that hazards are reasonably prevented or mitigated in order to maximize the safety of the vehicle operator, occupant(s), and passers-by.

As part of a continuous research and innovation effort, Ford Motor Company has been evaluating hydrogen as an alternative fuel option for vehicles with internal combustion engines since 1997. Ford has recently designed and built an Econoline (E-450) shuttle bus with a 6.8L Triton engine that uses gaseous hydrogen fuel. Safe practices in the production, storage, distribution, and use of hydrogen are essential for the widespread public and commercial acceptance of hydrogen vehicles. Hazards and risks inherent in the application of hydrogen fuel to internal combustion engine vehicles are explained. The development of a Hydrogen Management System (H2MS) to detect hydrogen leaks in the vehicle is discussed, including the evolution of the H2MS design from exploration and quantification of risks, to implementation and validation of a working system on a vehicle. System elements for detection, mitigation, and warning are examined.
