Publication number: 20200320257Abstract: A control and processing system for use with an interrogator and an interrogation system employing the same. In one embodiment, the control and processing system includes a correlation subsystem having a correlator that correlates a reference code with a reply code from a radio frequency identification (RFID) tag and provides a correlation signal therefrom. The control and processing system also includes a decision subsystem that verifies a presence of the RFID tag as a function of the correlation signal.Type: ApplicationFiled: April 20, 2020Publication date: October 8, 2020Applicant: Medical IP Holdings, LPInventors: John P. Volpi, Logan Scott, Eric McMurry

Publication number: 20200160005Abstract: An interrogator, methods of discerning the presence of an object, and interrogation systems employing the same. In one embodiment, the interrogation systems include multiple interrogators that communicate with a base command unit to track a location of an object. In another embodiment wherein the object is an RFID object (e.g., an object with an RFID tag), the interrogators employ signal processing techniques such as precharging the RFID object, and correlating a reference code with a reply code from the RFID object using selected techniques to increase a sensitivity of the interrogator, especially for adverse environments. In other embodiments, the interrogation systems include variations of metal instruments and sponges employed therewith. In yet another embodiment, the interrogation system includes metal interrogators capable of discerning the presence of a metal object, especially in a presence of another metal object.Type: ApplicationFiled: September 16, 2019Publication date: May 21, 2020Applicant: Medical IP Holdings, LPInventors: John P. Volpi, Jimmy D. Laferney, David W. Hensley, Robert C. Hatch, Glenn W. Boisbrun
