Alps Electric Developed 3-Axis Electronic Compass: The World's Smallest Compass with Angle Compensation Functions.TOKYO -- Alps Electric (Pink Sheet:APELY) has developed a three-axis electronic compass for mobile phones and other compact mobile devices. To contribute to equipping compact mobile devices with navigation functions Navigation function usually refers to a function of position, velocity, acceleration and time which is used to plan robot trajectories through the environment. Generally, the goal of a navigation function is to create feasible, safe paths that avoid obstacles while allowing a , Alps Electric became the world's first company to load a compass with three magnetic sensors, leading to the development of the world's smallest (3.5mm width x 3.5mm depth x 1.0mm height) three-axis electronic compass with angle compensation functions. Alps Electric leveraged its unique high-precision, high-density mounting technology in order to enable the loading of the new compasses into mobile phones and other compact devices. While minute, this electronic compass also makes use of an advanced magnetic sensor for high-precision sensing functions. The three magnetic sensors on the compass incorporate Alps' proprietary algorithms for maximum performance, as well as Alps' proprietary Giant Magneto magneto: see generator. magneto Permanent-magnet alternating generator used mainly to produce electrical current for the ignition system in various types of internal-combustion engines, such as aircraft, marine, tractor, and motorcycle engines.

Through these, the compass offers angle compensation functions, magnetic field correction functions and automatic terrestrial magnetism the magnetic force exerted by the earth, and recognized by its effect upon magnetized needles and bars.

Accordingly, angle compensation functions are used to accurately detect the direction in which the user is headed. In terms of magnetic field correction, when the compass is loaded inside a device with multiple components, effects on its magnetic field due to magnetic noise from other parts is avoided. This assures its high performance as a part, and contributes to better device engineering.
