The topics below are proposed by Freescale. Chosing one of them is not mandatory, you are free to come with your own idea for a topic. HMI - Human Machine Interface An HMI is a car system that allows the driver to easily use different information and entertainment car services. The HMI is usually found at the center of the car, between the driver and the passenger. A typical HMI can be a touchscreen allowing access to Radio & Audio subsystems as well as Navigation and Phone Connectivity. The teams chosing this project will need to design a graphical interractive application that allow the user to: Play media from various external devices (SD card or smartphone) Adjust audio and video settings Make and receive phonecalls from a smartphone connected to the Wandboard Use the navigation system Examples of HMI below: http://www.youtube.com/watch?v=iZsviUeLmmg Audi New HMI at CES2014 - YouTube Freescale Automotive Vision Freescale i.MX 6 Automotive Technology Audio Post Processing Filter Audio post processing, is the intentional alteration of auditory signals, or sound, often through an audio effect or effects unit. When listening to radio or music in a car, the surroundings around the listener can reduce the quality of listening experience. Traffic or wheel noise, people talking can contribute a lot of noise -- so much noise that some of the soft pieces in the music may become inaudible.Audio post processing can be used to improve the user experiencer by supressing the effects produced.by various noises. The teams chosing this project will have to show sample audio streams recorded with noises and the resulted output after the post processing alghorithms have been applied. Check out the links below dor more details: DSP-based audio post processing enhances audio quality | EE Times Audio signal processing - Wikipedia, the free encyclopedia Real Time Collision Detection A collision avoidance system is a system designed to reduce the severity of an accident. Also known as precrash system, forward collision warning system or collision mitigating system, it uses radar and sometimes laser and camera sensors to detect an imminent crash. Once the detection is done, these systems either provide a warning to the driver when there is an imminent collision or take action autonomously without any driver input (by braking or steering or both). One of the first phases in collision avoidance collision detection or detecting an approaching obstacle. A typical application will process images received through a camera connected to the Wandboard, detect objects that are getting closer and closer (having a certain speed as a threshold) and warn by playing a sound or showing a warning message on the screen.  For more details, visit: HowStuffWorks "Pre-collision Systems and Radar" Collision detection - Wikipedia, the free encyclopedia Safety Critical Linux A life-critical system or safety-critical system is a system whose failure or malfunction may result in: death or serious injury to people, or loss or severe damage to equipment or environmental harm. Automotive software is an example of a safety critical system. There is currently a lot of debate on whether Linux SW can be part of a such a system and there are open source projects aimed towards proving this. One of the examples of such project is the OSADL Project: Safety Critical Linux. A team chosing this topic might contribute to this project with applications or tools that control Linux application behaviour in Autmotive environment Check out the links below for more information: https://www.osadl.org/Presentations-and-Documents.safety-critical-documents.0.html http://elinux.org/images/9/96/LinuxInSCEnvironment.pdf AFS - Adaptive Front-light System Approximately 70% of vehicle to pedestrian accident occured in night time. The AFS adapts automatically to the traffic situation and weather conditions for increased safety and greater driving comfort. The teams chosing this project will have to create a prototype for controlling the front-light to different situations: curves, bumps, other traffic vehicles.

The video shows the connection made using the OBD2 protocol, this current implementation opens the connection and then read the current RPM and simply prints it on the screen. The second video show the manifold presure, measure in the same way as in the first video.

Al doilea bonus al echipei Freya in care este prezentata capacitatea serei de a recunoaste comenzi vocale de a fi controlata prin intermediul acestora. In video sunt prezentate comenzile pentru citirea senzorilor (status), citirea limitelor(limits) si schimbarea limitei maxime a temperaturii (change maximum temperature). Cea din urma este apelata de 2 ori pentru a scoate in evidenta efectul ei asupra ventilatorului. Comenzile pentru schimbarea limitei minime a temperaturii, umiditatii si a nivelului de apa functioneaza in mod asemanator.

In the movie, we show that we wired the necessary connections to the 'T' pin (the red wire) of the board inside the headset, and to the ground, that needs to be common with the UDOO board's ground (the black wire). The wires are connected to the 0 (RX) pin and the GND pin of the UDOO board, respectively. Software-side, we used the Brain library which takes packets received from the serial interface and interprets them, giving values in CSV form, for us to process in the next step. For receiving data from the headset, the M4 core of the board runs the Arduino code and uses the Serial0 object (UART 5) to take the raw data, which is processed by the Brain library. Then, the resulting string is sent to the A9 core by using the provided shared memory. The Serial object is used for this step, as we see in the video. The received string contains values in the following form: signal strength, attention, meditation, delta, theta, low alpha, high alpha, low beta, high beta, low gamma, high gamma We will use them in the following milestones.
