Licensing Davidson Instruments Intellectual Property

The worldwide annual market for harsh industrial applications exceeds $1B. Davidson is seeking market leaders to acquire exclusive, worldwide field-of-use licenses to the Davidson intellectual property. A field-of-use license would enable market leader licensees to design, manufacture, and sell instrumentation based on Davidson’s intellectual property in selected fields-of-use where they already have strong position. A license to the Davidson technology will secure the licensee’s competitive position in the selected markets and will enable rapid product development, validation, qualification, market penetration, high volume production and worldwide commercialization.

The reasons to consider acquiring a license include the following:

A field-of-use license can be structured to provide the licensee with licensing options that can be used to lockup the technology in a selected field-of-use during the initial technology assessment phase. Then, once the licensing option has been exercised and the license granted, Davidson begins a comprehensive technology transfer program. Once, the technology has been transferred and the products are being manufactured, Davidson will be available to provide extensive support services to the licensee for as long as necessary.

Since the standard licensing agreement is heavily weighted on royalties, all licenses are exclusive in the defined field-of-use. This enables Davidson to work very closely with its licensing partners to maximize the chances of commercial success. The royalties provide Davidson with significant incentive to assure a very effective and thorough technology transfer leading to commercial success. This option and royalty approach to licensing minimizes the financial risk to the licensee.

Davidson has already licensed its intellectual property to Halliburton Energy Services for use in the downhole oil & gas reservoir performance monitoring field-of-use. Davidson’s drift-free, temperature-tolerant high pressure (20,000 psi) transducers are used for measuring downhole oil & gas reservoir pressure and temperature. This instrumentation is used for efficient and effective oil and gas production and when enhanced oil & gas recovery methods are needed in high temperature reservoirs.

Davidson is currently in discussion with parties regarding licenses in the following fields-of-use:

Gas Turbine Combustion Dynamics - Davidson’s combustion dynamics pressure transducers can operate continuously at temperatures exceeding 1000°F providing unprecedented accuracy, fidelity, and reliability for gas turbine combustion dynamics monitoring.  Because Davidson’s transducers can “take the heat” and are immune to electromagnetic interference, they are positioned to make direct measurements flush with the inner diameter of the combustion liner. The electronics can be seamlessly integrated with any monitoring, data archival, and control systems.

Plastics Injection Molding - Davidson’s drift-free, temperature-tolerant high pressure (30,000 psi) transducers and high-speed signal processors can be used for measuring the pressure of molten plastics in high speed injection molding processes to improve process control leading to improved yield and the production of high performance injection molded plastics

Fossil Power Generation - In addition to the measurement of combustion dynamics, there are a multitude of other sensors used on gas turbines and other fossil power generation equipment. A license to our technology to the fossil power generation field-of-use would enable the licensee to design, manufacture, and sell sensors and related instrumentation based on our intellectual property to make measurements of temperature, vibration, acceleration, load, position, density, level, and differential pressure.

Aerospace - The aerospace industry has made great strides in recent years deploying fiber optics and photonics technology because the technology provides so many fundamental advantages. This trend will continue as fiber optic systems evolve for various avionics, communication, and vehicle monitoring applications.   Aerospace instrumentation must be lightweight, immune to EMI/EMP, tolerant to elevated temperatures, and rugged enough to survive severe shock and vibration.  With Davidson’s lightweight and robust sensor technology, it is practical to replace conventional electronic sensors and related instrumentation with rugged low-cost fiber-optic alternatives.

Market research indicates that there is enormous market potential for temperature-tolerant instrumentation in the following fields-of-use. Davidson is unencumbered and is structured and free to carve out any field-of-use ranging from very narrow highly specialized applications to a very broadly defined fields-of-use.

Reciprocating Engines and Gas Compressors - Davidson’s in-cylinder pressure transducers can be used for in-cylinder monitoring of advanced natural gas reciprocating engines and compressors as well as gas turbines.  The high-speed signal conditioners convert the optical signals into electronic signals at 30 kHz providing the very fine temporal resolution required for the optimization and health diagnostics of advanced reciprocating engines and compressors. 

Industrial Process Control

Refining/Chemicals/Petrochemicals - The most fundamental measurements made in the process industries are pressure and temperature.  Because the electrical power used in all electronic transmitters is greater than the safe limit of electrical power, all transmitters and cabling used in explosion hazard areas of industrial plants require explosion-proof enclosures.  Because of the ultra-low light power levels involved in Davidson’s fiber optic-based instrumentation, the transducers and cabling are inherently safe and do not require explosion-proof containment.  This fundamental technical advantage allows a new paradigm in industrial measurements with the potential to eliminate significant cost and measurement errors.

Catalytic Reactor Temperature Profile - Proplyene oxide and ethylene oxide catalytic reactors are pressure vessels that contain thousands of tubes filled with catalyst.  To optimize the life of the catalyst and to safely control these catalytic reactors, it is essential that the operators know the temperature of the catalyst at any radial and axial position within the reactor.  Conventional electronic instrumentation cannot make temperature measurements with high enough spatial resolution to allow the operators to optimize performance or predict the life of the catalyst.  Davidson’s innovative high-resolution temperature profile probes solve the problem by providing a temperature profile with spatial resolution of 100 mm, ten times finer than conventional thermocouples or RTD and with a probe that has a cross-section less than one half the conventional temperature probes providing improved measurement accuracy and time response over conventional temperature instrumentation.

Laboratory Test and Measurement - Almost every new process or process improvement begins with the development of pilot plants and many pilot plants operate at elevated temperatures in explosion hazard areas and in EMI rich environments.  To minimize the cost, optimize the performance, and increase the margins of safety in these harsh industrial environments, advanced measurement technology is required.   Davidson’s innovative fiber optic instrumentation provides a cost-effective solution for any laboratory test and measurement issue that requires precise measurements at high temperatures or in explosion hazard or EMI-rich environments.  In addition, the small cross-section of the transducers and the ability to make multivariable measurements with a single interrogator provides significant advantages in laboratory and pilot plant applications. 

Specialty Oil & Gas Applications

Offshore Oil & Gas - Leaders in the offshore industry are beginning to realize the need for instrumentation that is not only accurate, reliable, and safe but also light in weight.  Davidson’s instrumentation is inherently safe, immune to EMI, and tolerant to high temperatures, and it is also light in weight for many reasons.  First, the transducers are very small compared to conventional transmitters and do not require explosion-proof enclosures.  Second, the transducers use rugged, lightweight, multi-strand optical cables eliminating the need for many heavy electrical cables and the associated explosion-proof conduit.  In the end, Davidson’s instrumentation suite has the potential to provide significant weight savings and lower life-cycle costs while eliminating many sources of errors and increasing the safety and reliability of the instrumentation.

High Temperature Subsea Instrumentation - Davidson’s pressure transducers can operate continuously at temperatures exceeding 500°F, well above the temperatures anticipated for any high temperature subsea applications.  Conventional electronic transducers are unreliable and subject to errors or failure when exposed to temperatures above 300°F.  Deep water subsea applications require instrumentation that is much more robust and tolerant to high temperatures to provide greater margins of safety and measurement accuracy over the life of the instrumentation and the subsea system.

Drill Ship Density / Level Measurement - Although modern drill ships are highly automated vessels, accurate and reliable measurement of the level and density of the mud due remains an unmet need.  Davidson’s innovative design for a mud level/density gauge immediately solves the safe measurement issue through ultra-low power fiber-optic sensors that operate at less than 5% of the lower limit of optical energy density that is considered the safe threshold.  Davidson’s inherently-safe mud pit density gauge can be used in the most hazardous of environments on a drill ship.

Clean Coal Power Generation - Advanced “clean coal” combustion technology involving acoustic tomography can be realized with Davidson’s temperature-tolerant, high performance instrumentation which does not introduce any frequency-dependent phase delays.  A breakthrough in clean coal acoustic tomography could have enormous economic impact as a key enabling technology leading to significant improvements in environmental quality at coal burning power generation facilities worldwide.

Nuclear Power Generation - Davidson’s fiber optic-based instrumentation is designed to use radiation hardened cables that can function to 200 Mrad allowing the cables and transducers to be used in containment and for balance of plant operations significantly reducing the number and size of cabling egress points and allowing the signal processing to occur remotely in a benign environment outside of containment.  The Department of Energy is funding the development of temperature-tolerant optical instrumentation for advanced Small Modular Reactors (aSMR).   Future aSMR deployment will require new instrumentation and control architectures to withstand the extreme in-vessel environmental conditions.

Defense - The defense industry has made great strides in recent years deploying fiber optics and photonics technology on military platforms because the technology provides so many fundamental advantages. This trend will continue as fiber optic systems evolve for various equipment monitoring applications.  Defense instrumentation must be lightweight, immune to EMI/EMP, tolerant to elevated temperatures, and rugged enough to survive severe shock and vibration.  With Davidson’s lightweight and robust sensor technology, it is practical to replace conventional electronic sensors and related instrumentation with rugged high-performance fiber-optic sensing alternatives.
