| http://www.w3.org/ns/prov#value | - Although a capacitive charge-storing circuit 340 is depicted in FIG. 3, the charge-storing circuit 340 may alternatively include a battery or other circuit element that is capable of storing an electrical charge. [0025] The series resistor 342 is employed to limit the charge rate of the capacitor at power-up, thus preventing overloading or performance degradation of the clamping voltage source (e.
