Publication number: 20240093740Abstract: A braking device has a portion having a braking surface adapted to come into contact with an opposite facing braking surface to apply a braking action, the braking surface being circumferentially free from obstacles to allow relative rotation between the braking surface and opposite facing braking surface when mutually in contact, and defining, in any point with respect to a revolution axis if the braking surface is fixed, or a rotation axis if the braking surface is rotative, an axial direction, a radial direction, a circumferential direction, and a tangential direction. A support connecting portion is radially outside the braking surface, either radially away from or outside the braking surface or either radially close to or inside the braking surface. A cooling portion, included circumferentially and laterally to the support connecting portion, has a plurality of axially through-openings adapted to increase a heat exchange surface and unadapted to create connecting surfaces.Type: ApplicationFiled: December 10, 2021Publication date: March 21, 2024Applicant: BREMBO S.p.A.Inventors: Pierangelo Gherardi, Daniele PENATI, Raffaello PASSONI, Simone TURANI, Matteo BOTTIN, Marco CARONIA

Patent number: 11696072Abstract: An electro-acoustical transducer such as a Piezoelectric Micromachined Ultrasonic Transducers is coupled with an adjustable load circuit having a set of adjustable load parameters including resistance and inductance parameters. Starting from at least one resonance frequency or at least one ring-down parameter of the electro-acoustical transducer a set of model parameters is calculated for a Butterworth-Van Dyke (BVD) model of the electro-acoustical transducer. The BVD model includes an equivalent circuit network having a constant capacitance coupled to a RLC branch and the adjustable load circuit is coupled with the electro-acoustical transducer at an input port of the equivalent circuit network of the model of the electro-acoustical transducer. The adjustable load parameters are adjusted as a function of the set of model parameters calculated for the BVD model of the electro-acoustic transducer to increase the bandwidth or the sensitivity of the electro-acoustic transducer.Type: GrantFiled: November 2, 2021Date of Patent: July 4, 2023Assignee: STMicroelectronics S.r.l.Inventor: Marco Passoni

Patent number: 11579273Abstract: A method of operating electro-acoustical transducers such as PMUTs involves applying to the transducer an excitation signal over an excitation interval, acquiring at the transducer a ring-down signal indicative of the ring-down behavior of the transducer after the end of the excitation interval, and calculating, as a function of said ring-down signal, a resonance frequency of the electro-acoustical transducer. A bias voltage of the electro-acoustical transducer can be controlled as a function of the resonance frequency. An acoustical signal received can be transduced into an electrical reception signal and a damping parameter of the electro-acoustical transducer can be calculated as a function of the ring-down signal so that a cross-correlation reference signal can be synthesized as a function of the resonance frequency and the damping ratio of the electro-acoustical transducer.Type: GrantFiled: January 6, 2022Date of Patent: February 14, 2023Assignee: STMicroelectronics S.r.l.Inventors: Marco Passoni, Niccolò Petrini
