Latest Patents

One of Parkkonen's latest patents is a "Method for interference suppression in a measuring device." This invention describes a method that enables a device to shield itself from strong magnetic interference fields while measuring weak biomagnetic signals. The measurement sensors are equipped with a feedback compensation loop, which generates a difference signal from the sensors themselves. The feedback function is actuated by one or more coils that eliminate external interference fields in the sensor region. The control logic employs the SSS method to numerically separate the biomagnetic signal from interference sources. Additionally, the interference suppression can be enhanced by placing the sensor assembly within a magnetically shielding room.

Another significant patent is "Determining a position of objects in a predetermined coordinate system." This invention relates to a method and device for determining the location and position of an object in relation to another object using electromagnetic signals. The arrangement involves two objects, one equipped with signal sources that generate electromagnetic signals, while the other contains receivers for measuring these signals. This method is particularly useful in MEG measurements, where the object with transmitters is typically the human head, allowing for the precise localization of brain activity signals.
