POSITION DETECTION SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18249677 titled 'POSITION DETECTION SYSTEM
Simplified Explanation
- The patent application describes a position detection system that uses a magnetic pole block and a magnetic sensor. - The magnetic pole block consists of multiple magnetic poles arranged in a specific direction, with N and S poles alternating. - One of the components, either the magnetic pole block or the magnetic sensor, can move in the same direction as the arrangement of the magnetic poles. - The magnetic sensor includes multiple magnetoresistive effect elements and a bias magnet. - The magnetoresistive effect elements are arranged side by side in the same direction as the magnetic poles. - The bias magnet applies a magnetic field to the magnetoresistive effect elements, orienting it towards one of the two opposite sides of the direction. - The purpose of this system is to accurately detect the position of the movable member in relation to the fixed member using the magnetic poles and the magnetoresistive effect elements.
Original Abstract Submitted
A position detection system includes a magnetic pole block and a magnetic sensor. The magnetic pole block includes a plurality of magnetic poles arranged in a first direction. The plurality of magnetic poles are arranged such that N poles and S poles are alternately arranged as the plurality of magnetic poles in the first direction. At least one member selected from the magnetic pole block and the magnetic sensor is movable in the first direction with respect to the other member. The magnetic sensor includes a plurality of magnetoresistive effect elements and a bias magnet. The plurality of magnetoresistive effect elements are arranged side by side in the first direction. The bias magnet applies, to the plurality of magnetoresistive effect elements, a magnetic field having an orientation toward one of two opposite sides of the first direction.
