Abstract: A magnetic tracking device is configured to track an object in an environment by receiving a measurement of the non-magnetic signal and a corresponding measurement of the magnetic signal for a location of the magnetic tracking device in the environment. The magnetic tracking device estimates, based on the measurement of the non-magnetic signal, a non-magnetic pose of the magnetic tracking device in the environment for the location. The device estimates, based on the measurement of the magnetic signal, a magnetic pose of the magnetic tracking device in the environment for the location. The device determines a difference between the magnetic pose estimate and the non-magnetic pose estimate for the location. The device determines a magnetic distortion correction value for the location based on the difference. The magnetic tracking device generates a distortion correction model including the distortion value and outputs a representation of the distortion correction model.

Abstract: Purifying target biomolecules, such as nucleic acids or proteins, from a biological source is a time intensive process and is typically performed by a skilled technician or scientist owing to the highly technical nature of the work. Systems, devices, and methods disclosed herein enable the automated bioprocessing and purification of target biomolecules from a biological source. For example, an instrument and disposable cartridge are provided for automatedly isolating and purifying nucleic acids (such as plasmid DNA from a bacterial culture) or for isolating protein from any biological sample. Such an exemplary instrument and cartridge can work in concert to timely release, mix, and move the target biomolecule and various reagents and buffers through a target biomolecule purification process, resulting in a purified target biomolecule with less manual oversight than traditional approaches.
