Linear Research Associates formed in 1974 to design and fabricate
electronic instrumentation systems for research
groups at Cornell University. Since that beginning, the scope
of Linear's work has grown to encompass a wide range of applied research
and development projects in physics and electrical engineering.
One such project, commissioned in 1991, was a request for study and
recommendation of a possible solution to an EM site magnetic field problem.
In response to this request, Linear Research
Associates developed and installed a prototype wideband active-feedback
system which reduced interfering magnetic fields by a factor of approximately 20. Not
long after installation of the prototype, Linear received third-party
inquiries about the system and, eventually, purchase orders for additional
prototype
systems. In mid-1992, Linear finalized an improved commercial
design of the active-feedback system, filed for patent protection and
initiated production of its current EMFC-series active magnetic field
compensation product line.
A series of significant performance upgrades have been implemented
since that time, including the introduction of an extended range ("QDC")
version for compensating slowly-varying magnetic fields due to movement of
elevators, trucks, subway trains, etc.
In 1995, the U.S. Patents and Trademarks Office granted Linear
Research Associates two fundamental patents covering its unique wideband active-feedback
magnetic shielding technology.
Since 1992, EMFC-series magnetic field compensation systems
have been successfully installed at many EM sites throughout the
United States and internationally. We take great pride in both our proven technical excellence in
diagnosing and solving magnetic interference problems and in our close
and positive working relationship with customers.
