4. Look around and find five devices that are likely to have embedded computer control systems. Answer these questions for each device: a. What does the device do? b. What are the device's inputs? c. What are the device's outputs? d. How does the embedded computer improve the device? Does it provide more features? Does it improve performance? e. What are the biggest constraints on the device (size, cost, power, etc.)? f. Would it be possible to build the device using a different kind of controller (e.g. mechani- cal)? How would that affect the device's features, performance, cost, size, and weight
