When improvised explosive devices (IEDs) became a serious threat in Afghanistan and Iraq, Larry began considering how to extend the detection range of Nuclear Quadrupole Resonance (NQR) Spectroscopy technology being used to detect land mines and to detect explosives in luggage in order to detect IEDs from a safer distance. 

In the fall of 2004, Larry filed a provisional patent application for a system and method for a parametric NQR Spectroscopy system that combines a short range NQR probe signal with a longer range detector signal, where the NQR probe signal is used to excite a specimen (e.g., a piece of luggage) to modulate the detector signal enabling detection of a chemical of interest from the longer range.   A non-provisional patent application for the PNQR technology was then filed about a year later on December 17, 2005.  When CRR was founded in December 2006, Larry assigned the pending PNQR technology patent application to CRR.  CRR successfully prosecuted the patent application resulting in issued U.S. patents 7,170,288; 7,411,392; and 7,696,750

On April 7, 2010, CRR co-founded PNQR LLC, which was assigned rights to the three issued PNQR patents.  PNQR subsequently hired CRR to provide technical and project management services to PNQR as part of a proof-of-concept (POC) project during which Larry developed a time-coherent NQR system that he used to measure the NQR frequency of a sample of a material of interest.   Larry then developed a POC parametric NQR system, where a modulation of the detection signal corresponding to the known NQR frequency of the sample was successfully measured inside a controlled measurement environment.

Based upon the POC project, three provisional patent applications were filed relating to the time-coherent NQR and time-coherent PNQR technologies, which resulted in issued U.S. patent 8,744,809.  In late 2010, Larry conceived of the concept of using a PNQR system as an interface with a subject material, which can be a biomaterial, nanotechnology, badge, or some other object.   Generally, Larry recognized that when a subject material having certain NQR properties is known to be present, the PNQR system can be used for tracking the subject material, communicating with the subject material, and/or controlling power conversion and power storage by the subject material.  A provisional patent for the PNQR-subject material interface system was filed on January 4, 2011, which resulted in issued U.S. patent 8,952,699.
