Abstract: A dynamically self-adjusting magnetometer is disclosed. In one embodiment, a first sample module periodically generates an electronic signal related to at least one magnetic field characteristic of a monitored environment. A second sample module periodically generates an electronic signal related to at least one magnetic field characteristic of a monitored environment. A summing module sums the absolute value of the electronic signal from the first sample module and the electronic signal from the second sample module. A delta comparator module receives the electronic signals from each of the first sample module, the second sample module and the summing module and compares each of the electronic signals with a previously received set of electronic signals to establish a change, wherein an output is generated if the change is greater than or equal to a threshold.

Abstract: A self-calibrating magnetic field monitor is disclosed. In one embodiment, a magnetic field sensor repeatedly generates an electronic signal related to the magnetic field. In addition, a calibration module generates a relative baseline signal based on an average value of the electronic signals for a given time period. A comparator compares the electronic signal with the relative baseline signal and generating an output signal if a difference in the comparing is greater than or equal to a threshold.

Abstract: A system and method for monitoring for a specified frequency band is disclosed. The technology initially utilizes a micro-electromechanical system (“MEMS”) based acquisition device to monitor an environment. The MEMS device receives a signal from the environment, and generates an input signal comprising an electronic representation of the received environmental signal. This input signal is then conditioned for at least one frequency band. Embodiments of the invention next allow the conditioned signal to be compared to various pre-defined events in order to determine the signal's origin.

Abstract: A system and method of environmental monitoring and event detection is disclosed. The technology utilizes a micro-electromechanical system (“MEMS”) based acquisition device to monitor an environment. An environmental input signal is received at the MEMS based acquisition device, and an electronic input signal is generated that corresponds to the environmental input signal. This electronic input signal is prequalified for a specific frequency band, compared to a database of reference signals each having an associated event frequency range, and conditioned to generate a conditioned signal with a refined frequency spectrum when the comparison results in a match. The conditioned signal is then utilized to identify at least one event attribute corresponding to an event associated with the electronic input signal, and the identified event attribute is outputted.
