Today’s automobiles provide a prime example. In a single vehicle, you can find Wi-Fi, Bluetooth, satellite radio, GPS systems, LED lights, air conditioning, power steering, anti-lock brakes, rear-view cameras, and other instrumentation. Numerous items also operate using dc motors, including power seats, adjustable mirrors, windshield wipers, power windows, and sunroofs. This same example could also apply to items ranging from Wi-Fi or Bluetooth-enabled appliances like washing machines, espresso machines, medical instruments, and even medical implants.
