Abstract: A system is disclosed for assessing roadway toll charges across a plurality of tolling agencies, for example a nation-wide system that allows use of a multi-protocol RFID tag that is recognized in a plurality of states having different tag protocols in their electronic tolling systems. In an embodiment, each tolling agency sets aside numbers associated with the national system. Where a tag is read that is not identified as part of the national system, the local agency processes the tag transaction. There a tag is read that is identified as part of the national system, regardless of which tolling agency reads it, the transaction information is sent to a national customer service center for processing.

Abstract: Systems and methods for disabling transponders used in electronic toll collection or other RFID systems, wherein the transponders include an antenna and RFID circuitry. The transponders can be selectively disabled by releasably securing a disabling device having a metallic portion at an operative position over the antenna of the RFID system, whereupon the metallic portion is coupled to the antenna in such a manner as to disable the RFID circuitry so long as the disabling device is at the operative position. The RFID circuitry is arranged to be automatically enabled upon removal of the disabling device from the operative position.

Abstract: The present invention provides improved electrosurgical instruments and systems having electrocautery energy supply conductors that provide inhibited current leakage and methods of performing a robotically controlled minimally invasive surgical procedure while preventing unintended capacitive coupling. A surgical instrument generally comprises an elongate shaft having a proximal end and a distal end and defining an internal longitudinally extending passage. An electrocautery end effector is coupled to or disposed at the distal end of the shaft. An interface or tool base is coupled to or disposed at the proximal end of the shaft and removably connectable to the robotic surgical system. Typically, an independent electrical conductor extends from the interface to the end effector to transmit electrical energy to tissue engaged by the end effector. A sealed insulation tube extends within the passage and over the conductor. A separation is maintained between the sealed insulation tube and the conductor.
