Electric Scooter Governor A town has a new light rail system. To encourage its use, the town council approved installing electric scooters at each station for riders to rent cheaply to take them to their final destinations. The town hired a small start-up company to provide location finding and speed control for each scooter. The new company determined that they can identify the scooters' locations using a GPS receiver/transponder. Since the location of each scooter is known, the GPS software can also determine the speed limit zone in which the scooter is driving. The GPS unit can then produce a voltage signal that is proportional to the speed limit. For the speed limit, the GPS unit outputs a linear o V at o miles per hour (mph) to \(5 \mathrm{~V}\) for \(50 \mathrm{mph}\). You must design a circuit that determines when the scooter's speed is above the limit and then output a \(5-\mathrm{V}\) signal. You find a suitable speed sensor that outputs a linear \(\mathrm{O}-\mathrm{V}\) to \(10-\mathrm{V}\) output with a nominal \(2-\Omega\) series resistance. The sensor outputs \(10 \mathrm{~V}\) at \(\mathrm{o} \mathrm{mph}\) and \(\mathrm{oV}\) at 100 \(\mathrm{mph}\). The maximum speed allowed on each scooter is \(55 \mathrm{mph}\). Design a system to use the sensor's speed output to mesh with the GPS unit's output to send an appropriate overspeed signal to the speed limiting system.
