Bicycle automatic braking system, eye tracking system and GPIB screen saver win top honors for TI's DesignStellaris 2010

Designs from more than 60 countries demonstrate how Stellaris(r) microcontrollers drive innovation around the world

Austin (September 21, 2010) – Showcasing how far Stellaris ARM® Cortex™-M3-based microcontrollers (MCUs) can take designs, Texas Instruments Incorporated (TI) (NYSE: TXN) today announced that Richard Wotiz’s innovative Bicycle ABS Brake System took top prize in the DesignStellaris 2010 contest. Commissioned to inspire technological advancement through healthy competition among engineers around the globe, the challenge was accepted by almost 1,000 contestants from more than 60 countries. Wotiz’s Bicycle ABS Brake System leverages the advanced connectivity, data efficiency, motion control features, and performance of TI's Stellaris LM3S9B96 MCU to control brake force to reduce wheel skid. By measuring force applied to a bike’s brake levers and the speed of both wheels, the system can detect skipping and then automatically drive a pair of stepper motors that ease up on the brakes. An adjustment knob enables the rider to choose performance settings for various trail surfaces.

For the challenge, developers used Keil™ Microcontroller Development Kit (MDK-ARM) software tools to create unique hardware- or software-based applications that showcase technologies enabled by TI’s Stellaris LM3S9B96 MCU as well as the capabilities of the on-chip SafeRTOS™ real-time operating system from Wittenstein. More than $10,000 in cash prizes and awards were distributed among the top three spots and 16 honorable mentions, and articles featuring the innovative designs will be published in future editions of Circuit Cellar magazine.

Second place went to Osamu Tamura of Japan for the camera-based eye-tracking system that uses the Stellaris MCU as a USB host, Ethernet node and camera controller. The solution switches between calibration and tracking modes via a button on the board, and results can be monitored by multiple PCs on a network. Sylvain Davaine of France took third place with the GPIB Screen Saver that serves as a USB stick-based screenshot capture tool with a direct connection for all GPIB instruments, including lab equipment, to greatly simplify reporting. Additionally, honorable mentions were awarded to 16 diverse designs including a six-axis articulated robot, a secure ACC PIN reader, a lithium-ion battery module, an electronic motorbike, a 2.4 GHz RC radio system, a networked real-time gas leak detector, a hands-free (eye-tracking controlled) USB mouse, and a handheld pollen sensor.

TI’s broad portfolio of MCUs and software
