BACKGROUND Counting the sponges is an important step in surgical procedures. A miscount may impact the patient's health, and it also has legal implications for the surgeon. This is an experimental study evaluating radio-frequency technology used in the perioperative period to identify surgical sponges left in the peritoneal cavity of swine. METHODS Radio-frequency labeled-disc identification ...
Radio sensitivity serves as a commonly used parameter in wireless receiver systems. When excess antenna noise is introduced into the system, it results reduction of radiated sensitivity. This phenomenon, referred to desensitization, occurs upon connecting antennas. paper elucidates shared impedance coupling mechanism, which sheds light on how passive antennas can introduce system. To address th...
Radio astronomy is a passive service and is equipped to observe extremely weak signals from outer space. The sensitivity of current state-of-the-art telescopes is over ten orders of magnitude higher than in most communications systems. Although radio telescopes are best located in relatively remote areas, astronomical observations may be still hampered by man-made radio frequency interference (...
