Abstract: A URL adapter for a Web browser that enables the integration of telephone numbers into a web browser's address line for parsing as a URI. The URL adapter bypasses traditional search hook functions to identify potential telephone numbers. The URL adapter has access to a name server for translating names entered into the browser into telephone numbers. The URL adapter can also parse Web pages to self-identify telephone numbers.

Abstract: An impedance-compensated current transformer comprising a primary winding, a power source electrically coupled through the primary winding; a secondary winding magnetically coupled to the first primary winding, the secondary winding having a secondary winding impedance and a secondary winding resistance; and an impedance-compensation circuit electrically coupled across the secondary winding; wherein the impedance-compensation circuit actively reflects to the secondary winding a virtual impedance which is equal in magnitude and opposite in polarity to the secondary winding impedance.
