Latest Patents

Two of Hansen's latest innovations include the **Sourceless Orientation Sensor** and the **Hybrid Motion Tracker**.

The Sourceless Orientation Sensor is designed to measure three orientation angles—azimuth, elevation, and roll—within a fixed reference three-dimensional coordinate frame. It utilizes a three-axis magnetic sensor to detect variations in the Earth's magnetic field. This information is used to determine azimuth and roll angles after initial elevation measurements have been acquired through other means. The sensor’s design includes two embodiments: one that employs a separate device for elevation measurements, and another that integrates a three-axis accelerometer for absolute angle determination during slow movements alongside a two-axis rate sensor for velocity readings.

The Hybrid Motion Tracker provides a sophisticated system to capture human motion accurately. By combining magnetic field sensors and optical sources located on different limbs, this device reconstructs motion in real time. The system employs a fixed transmitter to emit electromagnetic energy while infrared light is transmitted to optical sensors. Through advanced algorithms, the computer calculates the position and orientation of each sensor, effectively enhancing accuracy through the integration of both technologies.
