Latest Patents
Carrington holds a patent for a groundbreaking invention titled "Screening Test for Transverse Magnetic-Field Excited Noise in Giant Magnetoresistive Heads." This patented method and system provides a rapid automatic screening mechanism for GMR heads, specifically targeting Barkhausen noise, which can significantly impact their performance. The process involves measuring the associated noise in a GMR head subjected to a smoothly varying external transverse magnetic field. Through the use of repeated measurements, the system sorts the data into bins, creating a histogram that evaluates the results against predetermined standards for automatic acceptance or rejection of tested GMR heads. The quantification of the GMR sensor Barkhausen noise is achieved via a bandpass filter to isolate noise signals, enabling reliable statistical analysis essential for automated quality control.
