Patent number: 11921922Abstract: A system for brain-based digital menu selection includes an acquisition device to obtain one or more electrical signals corresponding to an operator's brain response, a stimulation generation device to generate a first stimulus with one or more target options based on the operator triggering the system, a first database including a first classification model, and processor. The processor receives a first response from the acquisition device corresponding to an operator's brain response to the first stimulus with the one or more target options, determines a probability of intended target, when the probability of intended target option is higher than a predefined confidence threshold value, selecting the intended target option and presenting a second stimulus, or executing a final action, according to the selected target option, and storing the first response and the selected target option in the first database with a classification identifier identifying the operator.Type: GrantFiled: April 19, 2019Date of Patent: March 5, 2024Assignees: TOYOTA MOTOR EUROPE, CAMLIN ITALY S.R.L.Inventors: Jonas Ambeck-Madsen, Andrea Bellotti, Luca Ascari, Sergey Antopolskiy, Pietro Avanzini, Alessia Colucciello, Anna Marchenkova, Giovanni Vecchiato

Patent number: 8810227Abstract: In an embodiment, a method of operating a switched-mode power supply includes producing an error signal based on a difference between a power supply output voltage and a reference voltage. A clock frequency is produced that is proportional to the error signal up to maximum frequency, and a sensed current signal is produced that is proportional to a current in switched-mode power supply. The error signal is summed with the sensed current signal to produce a first signal, and the first signal is compared to a first threshold. The method also includes producing a first edge of a drive signal at a first edge of the clock signal, and producing a second edge of the drive signal when the first signal crosses the first threshold in a first direction based on the comparing, where the second edge opposite the first edge.Type: GrantFiled: January 14, 2011Date of Patent: August 19, 2014Assignee: Infineon Technologies Austria AGInventors: Marco Flaibani, Cristian Garbossa, Enrico Orietti, Andrea Vecchiato

Patent number: 8497714Abstract: In an embodiment, a method of driving a switch transistor includes activating the switch transistor by charging a control node of the switch transistor at a first charging rate for a first time duration. After charging the control node of the switch transistor at the first charging rate, the control node of the switch transistor is further charged at a second charging rate until the control node of the switch transistor reaches a target signal level, where the second charging rate is less than the first charging rate.Type: GrantFiled: January 14, 2011Date of Patent: July 30, 2013Assignee: Infineon Technologies Austria AGInventors: Cristian Garbossa, Andrea Vecchiato, Marco Flaibani, Enrico Orietti

Publication number: 20120153919Abstract: A method for controlling a switching converter is disclosed whereby the switching converter is configured to convert an input voltage into an output voltage supplied to a load in accordance with a switching signal, The switching converter is configured to operate in a pulse width modulation mode or, alternatively, in a pulse frequency modulation mode. When operating in the pulse width modulation mode, generating, as the switching signal, a pulse width modulated (PWM) signal of a pre-defined constant switching frequency. The PWM signal has a duty cycle that is regulated such that the output voltage of the switching converter matches, at least approximately, a desired output voltage under the condition that the duty cycle being regulated such that it does not fall below a predefined minimum duty cycle. The output voltage is monitored and switched over to the pulse frequency modulation mode when the output voltage exceeds a predefined first threshold.Type: ApplicationFiled: December 17, 2010Publication date: June 21, 2012Inventors: Cristian Garbossa, Marco Flaibani, Andrea Vecchiato, Enrico Orietti

Patent number: 8164319Abstract: A system and method for adapting a width of a clocking pulse for clocking a DC-DC converter, wherein the width of the clocking pulse is selected based upon the duty cycle of the DC-DC converter. When the DC-DC converter operates below a predefined threshold duty cycle, a clocking pulse of a first width is selected to allow operation of the converter at a minimum predefined duty cycle with a clocking frequency that minimizes output voltage ripple. The first width corresponds to an on-time of a switching transistor of the DC-DC converter when the converter is operated at the minimum duty cycle. When the DC-DC converter operates above the predefined threshold duty cycle, a clocking pulse of a second width is selected to allow operation of the converter at high duty cycles while simultaneously avoiding missed inductor current pulses and generation of sub-harmonic voltage oscillations.Type: GrantFiled: September 30, 2008Date of Patent: April 24, 2012Assignee: Infineon Technologies AGInventors: Emanuele Bodano, Andrea Morra, Andrea Vecchiato, Marco Piselli
