RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

RFID Could Save Your Leg...or Kidney, or...

By now you have heard horror stories of poor souls being wheeled into hospital operating rooms intending to have an operation on a designated appendage or organ, only to discover later that the highly trained staff mistakenly "fixed" problems the patients never had. Everything from the wrong leg being removed to sterilization has been performed due to miscommunications and lack of attention to details. Thanks to RF engineers, the likelihood of such mishaps are decreasing now. A company named SurgiChip, of Palm Beach Gardens, FL, has obtained the first FDA-approved surgical marking device that uses an RFID chip to positively identify a patient and provide a bit of data storage unique to a particular tag. Conceived of by an orthopedic surgeon, the SurgiChip is programmed with patient ID information and a description of what surgery needs to be performed, then it is taped to the patient in the vicinity of the affected body part. Once in the operating room, the doctor and a witness scan the RFID tag and confirm that the intended operation is the one they are about to perform. Given that a large percentage of reported surgical misadventures seem to have come from Florida hospitals, perhaps the company's location is no mere happenstance.
