Ultrasound triangulation system, has wireless signal transmitting device for triggering mobile transmitter to transmit ultrasound signal and mark start of time measurement

摘要

An ultrasound transmitter (4) is battery assisted and can operate as a mobile unit without cables. A wireless signal transmitting device (2) transmits electromagnetic waves (7) or ultrasound waves to the ultrasound transmitter in order to transfer a trigger signal to mark the start of a time measurement in an ultrasound evaluation unit (10), and also to trigger the mobile transmitter to transmit an ultrasound signal. An independent claim is included for a method of ultrasound triangulation.
