![]() The US patent system goes back to the very dawn of our nation. It doesn’t get more future-looking than this. Our most recent patents span artificial intelligence (AI), hybrid cloud, cyber-security and quantum computing. We are actively planting the research seeds of the bleeding edge technological world of tomorrow. The number of patents we produce each year - and in 2020, it was more than 9,130 US patents - demonstrates our continuous, never-ending commitment to research and innovation. A patent is evidence of an invention, protecting it through legal documentation, and importantly, published for all to read. ![]() Just like during the 13 years before and 15 years after, IBM has been getting more patents granted than any other company in the US.įor me, this patent leadership symbolizes much more than just the mere fact of being at the top. I also knew it had contributed to IBM’s patent leadership that year. ![]() This technology soon became the basis for how all advanced chips are manufactured, even to this date. It was a proud moment for me - especially as I knew that this patent contained novel capabilities that were critical for a brand-new technology called immersion lithography. Granted to my IBM colleagues and myself in 2005, it was for a topcoat waterproof material for a photoresist - a light-sensitive substance used to make circuit patterns for semiconductor chips. ![]()

![]() ![]() ![]() For modest geometric and modulus ratio configurations, the method obtains the perturbed stress intensity factors with reasonable accuracy using only four terms in IPE. ![]() The second boundary condition for continuity of stresses at the inclusion boundary is approximately satisfied through discrete-point collocation equations in a subsequent step through the inverse formation. The crack-face boundary condition is exactly satisfied in this step, without solving for the unknowns. The expression for PDD, determined through Gauss–Chebyshev Quadrature integration of the singular integral equations, is recast in terms of the unknown coefficients of IPE, which form the only set of unknowns. The inverse formulation presents mode-I crack–inclusion interaction solution, based on Eshelby’s equivalent inclusion method (EIM) with an unknown filed of induced polynomial eigenstrains (IPE) inside an inclusion, combined with the distributed dislocations technique (DDT) to model the crack face with unknown perturbations in distributed dislocations (PDD). ![]() ![]() The electronics are contained inside Fuchs's tough aluminium chassis, mounted on an extremely high quality printed circuit board, as opposed to the perforated Verotype board base that Fischer used. The rear of the cabinet has a full height baffle with a large circular port, echoing those seen on Dumble cabs. The white LED mains indicator is positioned to be the headlight in the train graphic on the far right of the panel - but it's a good idea not to stare at this for too long as it's extremely bright and could do with toning down. ![]() Fuchs uses a highly reflective license plate-type plastic for its badge we think it would be a good idea to use the same material for the control panels, as they're difficult to read unless you're really close. The cabinet is covered in thick black vinyl, which has been expertly applied, with white piping around the black grille cloth to accent the controls and logo. Incidentally, original Trainwrecks were never offered as combos, although one or two conversions have since been made. ![]() The Train 45 is built to Fuchs's usual high standards, with a tough, neatly finished cabinet housing the chassis and single 12-inch Celestion speaker. ![]() The Fuchs Train 45 has the usual audiophile Fuchs upgrades to bring it up to date, but does it have the mojo to compete with an original Trainwreck? Let's take a closer look. ![]() |
