Disclosed is a system and method for calibrating a magnetometer of a compass. With a global navigation satellite system receiver, a current position is determined. The determined position is used to determine a magnetic inclination (e.g., by a global magnetic field model such as the World Magnetic Model). The calibration system may perform different calibration sequences based on the magnetic inclination. In a first calibration sequence, performed responsive to a determination that a magnetic inclination (or the absolute value of the magnetic inclination) is less than a threshold, magnetic field data is measured by the magnetometer as it is rotated through horizontal rotation paths. If the magnetic inclination is greater than the threshold, magnetic field data is measured by the magnetometer as it is rotated through vertical rotation paths. The measured magnetic field data may be used to determine calibration values for the magnetometer compass. 1.

Facetted jewel bearings

Номер: US20160195852A1
Автор: Gregory HENDRICKS

The invention provides bearing systems characterized by single point contact with each jewel segment and a spring-loaded assembly with protection from radial and thrust forces. An important feature of jewel bearings of the invention is that they are self-lubricating, i.e., no oil or grease lubricants are needed. This can be a major advantage in medical and precision equipment. A secondary important feature is the reduced friction and effective heat-dissipation due to the unique design of the invention with significant reduction in contact surfaces and friction, which significantly prolong the lifespan of the bearings. Another advantage of the present invention is the substantial reduction in audible noise due to the unique design. Furthermore, the invention allows the use of relatively low cost synthetic jewel segments in bearings.
