Publication number: 20230322170Abstract: The present disclosure is directed to a device and method for detection of motion events including towing of the vehicle, jacking of the vehicle, and the vehicle being hit by another object. Processing is split between an MCU and a sensor unit. After the vehicle is turned off and before the MCU enters a sleep mode, the MCU calculates a gravity vector of the vehicle using accelerometer data, calculates threshold values based on the gravity vector, and saves the threshold values. After the MCU enters the sleep mode, the sensor unit subsequently monitors and detects motion events with the saved threshold values.Type: ApplicationFiled: April 11, 2022Publication date: October 12, 2023Applicant: STMICROELECTRONICS, INC.Inventors: Mahaveer JAIN, Mahesh CHOWDHARY

Publication number: 20230314138Abstract: At start-up of a microelectromechanical system (MEMS) gyroscope, the drive signal is inhibited, and the phase, frequency and amplitude of any residual mechanical oscillation is sensed and processed to determine a process path for start-up. In the event that the sensed frequency of the residual mechanical oscillation is a spurious mode frequency and a quality factor of the residual mechanical oscillation is sufficient, an anti-phase signal is applied as the MEMS gyroscope drive signal in order to implement an active dampening of the residual mechanical oscillation. A kicking phase can then be performed to initiate oscillation. Also, in the event that the sensed frequency of the residual mechanical oscillation is a resonant mode frequency with sufficient drive energy, a quadrature phase signal with phase lock loop frequency control and amplitude controlled by the drive energy is applied as the MEMS gyroscope drive signal in order to induce controlled oscillation.Type: ApplicationFiled: April 4, 2022Publication date: October 5, 2023Applicants: STMicroelectronics, Inc., STMicroelectronics S.r.l.Inventors: Yamu HU, Naren K.

Patent number: 11699667Abstract: A leadframe having extensions around an outer edge of a die pad are disclosed. More specifically, leadframes are created with a flange formed at the outer edge of the die pad and extending away from the die pad. The flange is bent, such that it is positioned at an angle with respect to the die pad. Leadframes are also created with anchoring posts formed adjacent the outer edge of the die pad and extending away from the die pad. The anchoring posts have a central thickness that is less than a thickness of first and second portions opposite the central portion. When the leadframe is incorporated into a package, molding compound completely surrounds each flange or anchoring post, which increases the bond strength between the leadframe and the molding compound due to increased contact area. The net result is a reduced possibility of delamination at edges of the die pad.Type: GrantFiled: May 3, 2021Date of Patent: July 11, 2023Assignee: STMICROELECTRONICS, INC.Inventor: Jefferson Talledo

Patent number: 11695053Abstract: Energy bands of a thin film containing molecular clusters are tuned by controlling the size and the charge of the clusters during thin film deposition. Using atomic layer deposition, an ionic cluster film is formed in the gate region of a nanometer-scale transistor to adjust the threshold voltage, and a neutral cluster film is formed in the source and drain regions to adjust contact resistance. A work function semiconductor material such as a silver bromide or a lanthanum oxide is deposited so as to include clusters of different sizes such as dimers, trimers, and tetramers, formed from isolated monomers. A type of Atomic Layer Deposition system is used to deposit on semiconductor wafers molecular clusters to form thin film junctions having selected energy gaps. A beam of ions contains different ionic clusters which are then selected for deposition by passing the beam through a filter in which different apertures select clusters based on size and orientation.Type: GrantFiled: September 20, 2022Date of Patent: July 4, 2023Assignee: STMICROELECTRONICS, INC.Inventor: John H.
