SYSTEMS AND METHODS FOR MEDICAL OBJECT TRACKING IN OBSTRUCTED ENVIRONMENTS

A system for alerting a medical provider of a possible displacement of a beacon includes the beacon, a control device, and a transceiver. The beacon includes sensors (for example, but not limited to, an IMU and a frequency shifter) and at least one antenna that exchanges signals with the transceiver. The IMU and the frequency shifter are used in a coordinated way to alert the medical provider if the beacon has been displaced in a way that might impact the medical procedure. As the beacon moves, when an anomalous correlation between the change over time of the IMU position data (of the beacon) and the frequency shifter position data (of the beacon) is detected, and the beacon has undergone a gravity/inertial moment (according to the IMU data) that exceeds a pre-selected threshold, the medical provider is alerted that the beacon's position might have shifted enough to impact the medical procedure.
