Patent number: 11949500Abstract: An integrated circuit includes a control circuit, a primary sensor device coupled to the control circuit, and a plurality of groups of secondary sensor devices coupled to the primary sensor device. The primary sensor device receives a master clock signal from the control device and outputs, to each group of secondary sensor devices, a respective secondary clock signal with a frequency lower than the primary clock signal. The primary sensor device generates primary sensor data. The primary sensor device receives secondary sensor data from each group of secondary sensor devices. The primary sensor device combines the primary sensor data and all of the secondary sensor data into a sensor data stream with a time division-multiplexing scheme and outputs the sensor data stream to the control circuit.Type: GrantFiled: August 29, 2022Date of Patent: April 2, 2024Assignee: STMicroelectronics S.r.l.Inventors: Matteo Quartiroli, Alessandra Maria Rizzo Piazza Roncoroni

Patent number: 11928065Abstract: In a digital communication system, a master device and a number of slave devices are coupled in communication with the master device over a shared data communication bus. A selection line for each one of the slave devices couples the master device with a respective slave device and is dedicated to selection by the master device of the respective slave device for communication over the shared data communication bus. Each of the slave devices is able to send an interrupt request to the master device over the respective selection line to be served by the master device initiating a communication over the shared data communication bus, each selection line thereby being a bidirectional communication line between the respective slave device and the master device.Type: GrantFiled: February 16, 2022Date of Patent: March 12, 2024Assignee: STMicroelectronics S.r.l.Inventors: Eyuel Zewdu Teferi, Alessandra Maria Rizzo Piazza Roncoroni

Publication number: 20230370524Abstract: The present disclosure is directed to a device and method for generating and transmitting a TDM signal including both raw data and processed data. The device includes a sensor having a time division multiplexing (TDM) interface. The TDM interface transmits both raw data and processed data in a single TDM signal by reserving one or more slots inside a TDM frame for transmission of the processed data. The sensor also embeds additional information inside a data stream of raw data by repurposing one or more of values of the raw data as an exception code, flag, or another type of notification. The device is also enabled to transmit data, and disabled when not in use in order to conserve power.Type: ApplicationFiled: July 27, 2023Publication date: November 16, 2023Applicant: STMICROELECTRONICS S.r.l.Inventors: Alessandra Maria RIZZO PIAZZA RONCORONI, Matteo QUARTIROLI, Rossella BASSOLI, Paola BALDRIGHI

Patent number: 9234755Abstract: A gyroscope includes a body, a driving mass, which is mobile according to a driving axis, and a sensing mass, which is driven by the driving mass and is mobile according to a sensing axis, in response to rotations of the body. A driving device forms a microelectromechanical control loop with the body and the driving mass and maintains the driving mass in oscillation with a driving frequency. The driving device comprises a frequency detector, which supplies a clock signal at the frequency of oscillation of the driving mass, and a synchronization stage, which applies a calibrated phase shift to the clock signal so as to compensate a phase shift caused by components of the loop that are set between the driving mass and the control node.Type: GrantFiled: May 3, 2013Date of Patent: January 12, 2016Assignee: STMicroelectronics S.r.l.Inventors: Luciano Prandi, Carlo Caminada, Alessandra Maria Rizzo Piazza Roncoroni
