说明：  • Hand-held, battery operated units, such as Medical instruments like Blood Glucose Meters and Blood pressure meters, or Security Lockboxes and Electronic Key locks • AC-powered units with SuperCap backup, such as small appliances, like a Timed coffee maker or light timer • Wireless sensors, such as a Window-mounted Glass Break sensor • Units that “steal” power from a low voltage system, as in an HVAC thermostat powered by a 24V AC transformer or in an Industrial sensor application that draws power from a 4mA-20 mA current loop • Energy harvesting units where the application runs off very small, rechargeable Li-Ion batteries that are charged from incidental energy sources like photo-voltaic, wind, RF, vibration or thermal.
