With a total of three patents to his name, Duane has significantly contributed to the fields of biomagnetism and information storage, addressing some of the pressing challenges in these areas.

Latest Patents

One of Duane's notable patents is for a "Measurement of Visually Induced Biomagnetic Responses." This innovation focuses on a biomagnetometer that measures the magnetic field produced by the brain as a result of visual stimuli from devices such as cathode ray tubes (CRTs). By filtering out unwanted noise from the display device's operation, including the repetitive scan signals, the biomagnetometer can more accurately detect brain signals. To enhance its effectiveness, the device employs a comb-notch filter along with cancellation coils and shielding to minimize interference.

Another significant patent is his work on a "Superconducting Information Storage Device." This invention features a magnetic recording medium supported on a rotating disk, coupled with an electromagnetic writing device that encodes magnetic patterns. The use of a superconducting quantum interference device (SQUID) allows for highly sensitive reading of these patterns, even from a distance. The incorporation of high-temperature superconductors facilitates practical construction, and the potential for multiple write devices and arrays of SQUIDs allows for efficient reading and writing across the disk.
