Abstract: Various systems and methods for detecting electron spins using electron paramagnetic resonance are described. An excitation signal generator configured to generate an excitation signal of varying amplitude and phase as compared to a reference signal may be present. A crossed-loop resonator configured to isolate a detection signal produced by the excitation signal exciting an object with a magnetic field may also be present. Further, a detection device configured to detect electron spins of the object using the detection signal isolated by the crossed-loop resonator may be present.

Abstract: Systems and methods are disclosed to simulate a Hall probe, provide EPR coil driver, and/or perform a time-domain full scan sinusoidal deconvolution of EPR signals. The simulated Hall probe can return a Hall Effect voltage from a coil current that creates a magnetic field within a coil magnet and the reference current that would be fed to an actual Hall probe. From these values, the Hall Effective voltage can be determined which can be used to determine the magnetic field flux, which can then be used to regulate the magnetic field. Embodiments of the invention also disclose a coil driver and a new technique for EPR deconvolution.

Abstract: A method for operating a multi-segment repeater hub wherein at least some of various signal ports connecting signaling stations to the hub can be connected selectively to different segments of the hub, comprising: monitoring signal traffic between the stations and the hub and thereby establishing a database which indicates for each of a plurality of ports the volume of signal traffic between the respective port and each other port in said plurality and any segment through which any of said signal traffic flows and to which a port other than a port in said plurality is connected, computing the traffic to and from the ports in said plurality and said segments and the traffic between the segments for each of a plurality of possible configurations in each of which a selected port is notionally moved from connection to one segment to connection with another segment; computing according to selected criteria a preferred set of connections to the ports to the segments, and switching the connections of the ports and s
