Abstract
A hybrid infrared-ultrasound real time location system includes at least one emitter having an infrared transmitter and a plurality of ultrasound transmitters and at least one tag. The tag receives an infrared signal from the infrared transmitter and ultrasound signals from the ultrasound transmitters. The time between the time-of-arrival of the IR signal and the time-of-arrival of each ultrasound signal is calculated and used to measure the respective time-of-flight of each of the US transmissions from the US transmitters to the tag and compute location.
