An inventory system configured for detecting and counting potentially retained surgical items within a body of a patient includes a tag configured to transmit a return signal including an electrical characteristic when energized, a signal generator configured to generate an energizing signal for the tag, an antenna operably coupled to the signal generator and configured to receive at least the return signal transmitted by the tag, a processor, and a memory. The memory includes instructions stored thereon, which, when executed by the processor, cause the inventory system to energize the tag by the energizing signal, receive the return signal from the tag by the antenna, and determine a presence of the beacon tag based on the electrical characteristic.

Inventory systems and methods for detecting and counting potentially retained surgical items

An electric-field capacitive coupler module includes a first processing unit, a first communication interface coupled to the first processing unit, a second communication interface, and an electric-field capacitive coupler that defines an isolation barrier. The electric-field capacitive coupler apparatus is coupled between the first communication interface and the second communication interface.

An electrosurgical system is disclosed. The electrosurgical system includes a multiple-secondary transformer configured for sensing voltage. The multiple-secondary transformer includes a primary winding coupled to an active terminal and a return terminal of the electrosurgical system and a plurality of secondary windings. Each of the secondary windings is configured to transform the radio frequency voltage into a sensed voltage. Each of the secondary windings includes an output coupled to a sensor circuit and configured to transmit the sensed voltage to the sensor circuit.
