Abstract
Systems and methods for arranging magnetic sources for producing field patterns having high gradients for precision positioning, position sensing, and pulse generation. Magnetic fields may be arranged in accordance with codes having a maximum positive cross correlation and a maximum negative cross correlation value in proximity in the correlation function, thereby producing a high gradient slope corresponding to a high gradient force or signal associated with the magnetic structure. Various codes for doublet, triplet, and quad peak patterns are disclosed. Applications include force and torque pattern generators. A variation including magnetic sensors is disclosed for precision position sensing. The forces or sensor outputs may have a precision zero crossing between two adjacent and opposite maximum correlation peaks.
