Patent number: 11889594Abstract: A system includes lighting devices coupled to output supply pins, a microcontroller circuit, and a driver circuit, which receives data therefrom, and switches coupled in series to the lighting devices. The driver circuit includes output supply pins and selectively propagates a supply voltage to the output supply pins to provide respective pulse-width modulated supply signals at the output supply pins. The driver circuit computes duty-cycle values of the pulse-width modulated supply signals as a function of the data received from the microcontroller circuit. The lighting devices include at least one subset coupled to the same output supply pin. The microcontroller individually controls the switches via respective control signals to individually adjust a brightness of the lighting devices in the at least one subset of lighting devices.Type: GrantFiled: March 11, 2022Date of Patent: January 30, 2024Assignees: STMicroelectronics (Grenoble 2) SAS, STMicroelectronics S.r.l., STMicroelectronics Application GMBHInventors: Manuel Gaertner, Philippe Sirito-Olivier, Giovanni Luca Torrisi, Thomas Urbitsch, Christophe Roussel, Fritz Burkhardt

Publication number: 20220214430Abstract: An electronic module for generating light pulses includes an electronic card or interposer, a LASER-diode lighting module, and a LASER-diode driver module. The interposer has an edge recess in which the lighting module is completely inserted. The driver module is arranged on top of the interposer and the lighting module. The electrical connections for driving the LASER diodes are obtained without resorting to wire bonding in order to reduce the parasitic inductances.Type: ApplicationFiled: January 4, 2022Publication date: July 7, 2022Applicants: STMicroelectronics S.r.l., STMicroelectronics (Rousset) SAS, STMicroelectronics Application GmbHInventors: Romeo LETOR, Roberto TIZIANI, Alfio RUSSO, Antoine PAVLIN, Nadia LECCI, Manuel GAERTNER

Publication number: 20220161019Abstract: Disclosed is a minimally invasive miniaturized percutaneous mechanical circulatory support system. The system may be placed across the aortic valve via a single femoral arterial access point. The system includes a low profile axial rotary blood pump carried by the distal end of a catheter. The system can be percutaneously inserted through the femoral artery and positioned across the aortic valve into the left ventricle. The device actively unloads the left ventricle by pumping blood from the left ventricle into the ascending aorta and systemic circulation. A magnetic drive and encased motor housing allows for purgeless operation for extended periods of time to treat various ailments, for example more than six hours as acute therapy for cardiogenic shock.Type: ApplicationFiled: November 18, 2021Publication date: May 26, 2022Inventors: Marvin Mitze, Hans Christof, Vladimir Popov, Martin Schwarz, Leon Wenning, Johannes Bette, Attila Fabiunke, Sina Gerlach, Johannes Stigloher, Julian Görries, Jan Schöfer, Valentin Rex, Johannes Berner, Bernhard Ehni, Johannes Ferch, Hans-Baldung Luley, Tom Döhring, Jens Burghaus, Inga Schellenberg, Hardy Baumbach, Annika Bach, Ingo Stotz, Julian Kassel, Armin Schuelke, Stefan Henneck, David Minzenmay, Thomas Alexander Schlebusch, Tobias Schmid, Tjalf Pirk, Martina Budde, Ricardo Ehrenpfordt, Marc Schmid, Ahmad Mansour, Niko Baeuerle, Ralf Strasswiemer, Uwe Vollmer, Manuel Gaertner, Fabian Eiberger, Tobias Baechle, Karin Schneider, Peter Wassermann
