Problem # 4 The Smart Shoe Problem: According to USA today, Adidas will place on the US market on March 15,2005 its Bionic shoe named Adidas-1. The Adidas-1 uses a sensor, a microcontroller, and a motorized cable system to automatically adjust the shoes cushioning. The sensor under the heel measures compression and decides whether the shoe is too soft or firm. That information is sent to the microcontroller and while the shoe is in the air, the cable adjusts the heel cushion." The Adidas webpage (http://www.adidas.com/1) explains, "The sensor monitors how much your shoes give under your weight down to the width of a human hair (80 microns). A MCU analyses the data performing 10000 calculations/sec, which are sent to the motor. The motor then gradually adjusts the cushioning of the shoe to ensure the perfect level for you. Just 4 steps from your front door and Adidas-1 has already figured out what type of cushioning you need." 1. Analyze this system and draw the flow diagram, or flowchart, that governs its function. Make it as granular analysis as you can for maximum credit. 2. Analyze the data acquisition for this system given the above resolution. How many bits are used by the processor to handle the calculations if the average jogging shoes will compress by up to 1 cm per step.
