Summary

Special Notice ENERGY, DEPARTMENT OF TECHNOLOGY/BUSINESS OPPORTUNITY Component-wise Reduced Order Model-based Lattice Design: Lawrence Livermore National Laboratory (LLNL) is offering the opportunity to license its component-wise reduced order model-based lattice design. This design aims to achieve 3D microstructures with high stiffness and light weight, which is important for LLNL's advanced materials and manufacturing capabilities. The current state-of-the-art approaches for designing these microstructures are either expensive and restrictive or cheap and inaccurate. LLNL's invention uses accurate Component-wise Reduced Order Models (CWROM) instead of inaccurate beam elements, making the process computationally efficient and fast. The CWROM-based design algorithm and uncertainty quantification techniques are expected to be implemented in LLNL codes such as MFEM, LiDO, and libROM. This technology has potential applications in efficient lattice design optimization, fuel consumption reduction in aerospace and automotive industries, smart honeycomb structure design for protection equipment, and safety design for shoes or helmets. LLNL is seeking industry partners to bring this technology to the market. Interested companies should provide a statement of interest including company information, relevant expertise, and facilities.

Description

Opportunity: Lawrence Livermore National Laboratory (LLNL), operated by the Lawrence Livermore National Security (LLNS), LLC under contract no. DE-AC52-07NA27344 (Contract 44) with the U.S. Department of Energy (DOE), is offering the opportunity to license its component-wise reduced order model-based lattice design. Background: Achieving 3D microstructures having high stiffness with light weight is an important goal for LLNL’s advanced materials and manufacturing capabilities.  Current state-of-the-art approaches of designing these microstructures are either too expensive & restrictive, or too cheap & inaccurate.  A new approach is needed that not only is fast, but also accurate. Description: Beam Element-based Topology Optimization (“BETO”) is one of the conventional ways to design microstructures.  It starts with an initial design that is composed of many beam elements.  LLNL’s invention uses accurate Component-wise Reduced Order Models (“CWROM”) rather than the inaccurate beam elements.  In doing so, the process becomes computationally efficient and fast, as each reduced order model is independent, thus leading to parallel computations.  LLNL researchers anticipate the CWROM-based design algorithm and uncertainty quantification techniques to be implemented in the following LLNL codes:  MFEM, LiDO, and libROM. Advantages/Benefits:  Fast and accurate computations and simulations Applicable to uncertainty quantification to determine effects of manufacturing flaws on system performance Extendable to nonlinear problems Potential Applications:  Efficient lattice design optimization using Reduced Order Models (ROM) Lattice structure alternative to save fuel consumption by reducing weight in aerospace and automotive industries Smart honeycomb structure to design protection equipment from impact Shoe or helmet design for safety Development Status:  Current stage of technology development:  TRL-3 LLNL has patent protection and copyrights on this invention. U.S. Patent No. 11,514,210 Reduced-Order Model Design Optimization such as for Lattice Design Optimization published 11/29/2022 LLNL is seeking industry partners with a demonstrated ability to bring such inventions to the market. Moving critical technology beyond the Laboratory to the commercial world helps our licensees gain a competitive edge in the marketplace. All licensing activities are conducted under policies relating to the strict nondisclosure of company proprietary information.  Please visit the IPO website at https://ipo.llnl.gov/resources for more information on working with LLNL and the industrial partnering and technology transfer process.

Special Notice ENERGY, DEPARTMENT OF TECHNOLOGY/BUSINESS OPPORTUNITY Space-Time Induced Linearly Encoded Transcription for Temporal Optimization (STILETTO) The Department of Energy (DOE) is offering the opportunity to collaborate with Lawrence Livermore National Laboratory (LLNL) to further develop and commercialize its Space-Time Induced Linearly Encoded Transcription for Temporal Optimization (STILETTO) technology. This technology allows for the generation of optical arbitrary waveforms with ~1 ps resolution and long records, which is currently not achievable with existing waveform generators. STILETTO works by transcribing an arbitrary record on a pulse front tilted (PFT) ultrafast pulse using a spatial light modulator (SLM) and a large grating. The patterned pulse is then coupled into a single mode system, such as a regenerative amplifier or optical fiber amplifier, to amplify the pulse to practical energy levels with low noise. This technology offers advantages such as long record lengths (nanoseconds) with high resolution (picoseconds), direct patterning in the time domain, and integration with ultrafast lasers. The potential applications of STILETTO include optical arbitrary waveform generation for wide bandwidth telecommunications and next-generation additive manufacturing. LLNL is seeking industry partners with the ability to bring this technology to the market. Interested companies should provide a statement of interest including company information, expertise in commercializing similar technologies, and contact details. To express interest in LLNL's STILETTO technology, please submit an electronic or written statement to the Lawrence Livermore National Laboratory Innovation and Partnerships Office. The subject heading in an email response should include the Notice ID and/or the title of LLNL's Technology/Business Opportunity. This is not a procurement notice, but an opportunity for collaboration and technology transfer.
