Publication number: 20240161720Abstract: A neural network emulates a behavior of a reference audio system for at least two control settings. A process, for each control setting, receives control position data designating a select control setting of the reference audio system as conditioning for the neural network, communicates an input to the reference audio system and captures a target output, maps parameters of the neural network such that, responsive to the input, a neural output resembles the target output, scores by a loss function, a similarity of the neural network output compared to the target output of the reference audio system, and utilizes the similarity derived from the loss function to modify model parameters of the neural network. A graphical user interface enables a user to select a virtual control setting within the graphical user interface such that the neural network models the reference audio system at the corresponding control setting.Type: ApplicationFiled: November 15, 2023Publication date: May 16, 2024Inventors: Douglas Andres Castro Borquez, Eero-Pekka Damskägg, Athanasios Gotsopoulos, Lauri Tuomas Jevela, Aleksi Tapani Peussa, Kimmo Erik Antero Rauhanen, Thomas William Sherson, Jaakko Makinen, Stylianos I.

Publication number: 20230119557Abstract: A process is provided for training a neural network that digitally models an audio system. A sound source is utilized to electrically couple a test signal into an input of a reference audio system. The output of the reference audio system is collected into an audio interface coupled to a computer. A neural network is then trained using the test signal and the captured information to derive a set of weight vectors with appropriate values such that the overall output of the neural network converges towards an output representative of the reference audio system, and a signal in the time domain from a musical instrument is processed through the trained neural network with a latency under 20 milliseconds. A graphical user interface then outputs a graphical representation of the trained neural network, where the graphical representation visually displays at least one virtual control for interaction by a user.Type: ApplicationFiled: December 16, 2022Publication date: April 20, 2023Inventors: Douglas Andres Castro Borquez, Eero-Pekka Damskägg, Athanasios Gotsopoulos, Lauri Juvela, Thomas William Sherson

Patent number: 11532318Abstract: A neural network is trained to digitally model a reference audio system. Training is carried out by repeatedly performing a set of operations. The set of operations includes predicting by the neural network, a model output based upon an input, where the output approximates an expected output of the reference audio system, and the prediction is carried out in the time domain. The set of operations also includes applying a perceptual loss function to the neural network based upon a determined psychoacoustic property, wherein the perceptual loss function is applied in the frequency domain. Moreover, the set of operations includes adjusting the neural network responsive to the output of the perceptual loss function. A neural model file is output that can be loaded to generate a virtualization of the reference audio system.Type: GrantFiled: January 9, 2020Date of Patent: December 20, 2022Assignee: Neural DSP Technologies OyInventors: Douglas Andres Castro Borquez, Eero-Pekka Damskägg, Athanasios Gotsopoulos, Lauri Juvela, Thomas William Sherson

Publication number: 20220261209Abstract: A robotic system is provided, which automatically changes settings on an audio system. The audio system (e.g., an instrument amplifier, effect processor, etc.) typically includes one or more controls that impact the operation of the audio system. Correspondingly, the robotic system includes a device interface coupled to a control sequencer. The device interface adapts to one or more controls of the audio system that are to be changed. In this regard, the device interface includes one or more control couplers. Each control coupler is adapted to a corresponding control of the audio system to be changed. The control sequencer provides a control sequence to the device interface that causes the control coupler(s) to vary the settings on the audio system. In practical applications, a combination of sequence values of the control sequence can represent a sufficiently high number of samples to determine a responsive behavior of the audio system.Type: ApplicationFiled: February 11, 2022Publication date: August 18, 2022Inventors: Douglas Andres Castro Borquez, Eero-Pekka Damskägg, Athanasios Gotsopoulos, Lauri Tuomas Juvela, Aleksi Tapani Peussa, Kimmo Erik Antero Rauhanen, Thomas William Sherson

Publication number: 20220262330Abstract: A system for emulating a physical audio system comprises a user interface (UI) and a digital model of the physical audio system. The UI comprises virtual controls for changing virtual control settings (e.g., a virtual volume control for changing a virtual volume setting, etc.). A change in a virtual control setting produces a change to the output of the digital model. Because the digital model emulates the behavior of the physical audio system, changes to the model output in response to changes in the virtual control settings correspond to changes in the audio output in response to changes in the physical control settings. For example, if the physical audio system is an audio amplifier with control knobs, then the virtual controls will affect the output of the digital model like the control knobs affect the audio output of the audio amplifier.Type: ApplicationFiled: February 11, 2022Publication date: August 18, 2022Inventors: Douglas Andres Castro Borquez, Eero-Pekka Damskägg, Athanasios Gotsopoulos, Lauri Tuomas Juvela, Aleksi Tapani Peussa, Kimmo Erik Antero Rauhanen, Thomas William Sherson

Publication number: 20220214710Abstract: A gyral-linear actuator for an encoder comprises an actuator housing having a first end, a second end opposite the first end, and a hollow. A control member extends from the first end of the actuator housing. A spring is positioned within the hollow of the actuator housing. Moreover, a coupler has an encoder connector and an extension that couples the control member to the encoder connector. Under this configuration, when the encoder connector is coupled to a rotary shaft of the encoder, rotation of the control member causes corresponding rotation of the encoder connector so as to turn the rotary shaft of the encoder, and depression of the control member causes corresponding depression of the rotary shaft of the encoder operating a switch function of the rotary encoder.Type: ApplicationFiled: January 19, 2022Publication date: July 7, 2022Inventors: Douglas Andres Castro Borquez, Franco Azocar Dellepiane

Patent number: 9469395Abstract: A multi-layered body system, including an inner body and an outer body, reduces the effects of turbulence on a vehicle by generating a counteracting force that stabilizes the inner body. During operation of the vehicle, the inner body may be electromagnetically levitated within the outer body using mitigation devices, such as powered electromagnets. Such electromagnetic levitation may cause the outer body to absorb turbulent force, which may be absorbed throughout the outer body and/or cause the outer body to move (e.g., toward the inner body). The system may include sensors that detect turbulent force imposed on the outer body. A computer may calculate a counteracting force that should be applied based on the detected turbulent force, and cause a mitigating device to output the counteracting force. The counteracting force may be provided to resume EM levitation within operational parameters.Type: GrantFiled: March 14, 2016Date of Patent: October 18, 2016Inventors: Arnav Simha, Jacob Brower, Douglas Andre, Clinton Behling

Publication number: 20130286482Abstract: A temporary, moveable marker for directing emergency aircraft to a landing zone employs a set of four panels which are foldable into a compact configuration. These panels are deployed in a substantially rectangular configuration to provide markings for an emergency landing zone and are attached by three hinges. This creates two panels with hinges on the two interior sides of the respective rectangles and two panels, each with one hinge on one interior side. All panels have aligning apertures so that the panels can be collapsed on top of each other to form one rectangle with an aperture through which a screw can be placed and affixed with a wing-nut on the other end, thus keeping the four panels attached. The collapsed set of four panels lie flat with at least one handle on an exterior side to allow for easy storage and transportation.Type: ApplicationFiled: April 27, 2012Publication date: October 31, 2013Inventors: Douglas Andre Racicot, Glen Edgar Johnson

Patent number: 6284910Abstract: The post-translational addition of a farnesyl moiety to the Ras oncoprotein is essential for its membrane localization and is required for both its biological activity and ability to induce malignant transformation. The present invention describes design and synthesis of a farnesylpyrophosphate (FPP) analog, 8-anilinogeranyl pyrophosphate (AGPP) that is transferred to Ras by farnesyltransferase (FTase), in which the &ohgr;-terminal isoprene unit of the farnesyl group has been replaced with an aniline functionality. AGPP potently inhibited FTase activity in vitro (IC50=0.6 &mgr;M) and is highly selective showing little inhibitory activity against either geranylgeranyl-protein transferase type I (GGTase I) (IC50=31 &mgr;M) or the utilization of FPP by the enzyme squalene synthase (IC50=1000 &mgr;M). Kinetic analyses suggest that AGPP acts as a competitive inhibitor of FTase with respect to FPP.Type: GrantFiled: December 15, 1999Date of Patent: September 4, 2001Assignee: University of Kentucky Research FoundationInventors: Hans Peter Spielmann, Douglas A.
