Abstract:
Ultrasound Identification is a Real Time Locating System (RTLS) is used to automatically track and identify the location of objects using simple inexpensive nodes (badges/tags) attached to or embedded in objects and devices which then transmit an ultrasound signal to communicate their location to microphone sensors.Ultrasound-based IPS is considered a better alternative to passive Radio-frequency identification (pRFID) in complex indoor environments (such as hospitals), where radio waves may reflect off of metallic or ceramic objects, thereby compromising the positioning accuracy, or otherwise interfering with sensitive medical equipment
