Introduction

Russell W Church is a notable inventor based in Oakdale, MN (US). He has made significant contributions to the field of electronic article surveillance systems. With a total of 2 patents, his work has had a considerable impact on the industry.

Latest Patents

One of his latest patents is the "Dual status magnetic marker having magnetically biasable flux collectors." This innovative marker is designed for use in electronic article surveillance systems that operate with an alternating magnetic field. The marker features a magnetic responder element that includes a central switching portion and flux collectors on each end. These flux collectors concentrate the magnetic flux within the switching portion, ensuring that the flux density is sufficient to generate an appropriate response. The dual status capability is achieved by incorporating magnetizable keeper elements adjacent to the flux collectors. When these keeper elements are magnetized, they bias the flux collectors and inhibit magnetization reversal in response to an interrogation field. This design prevents the interrogation field's flux from being concentrated in the switching portion of the responder element.
