  • Publication number: 20240199408
    Abstract: A process for manufacturing a MEMS device includes forming a first structural layer of a first thickness on a substrate. First trenches are formed through the first structural layer, and masking regions separated by first openings are formed on the first structural layer. A second structural layer of a second thickness is formed on the first structural layer in direct contact with the first structural layer at the first openings and forms, together with the first structural layer, thick structural regions having a third thickness equal to the sum of the first and the second thicknesses. A plurality of second trenches are formed through the second structural layer, over the masking regions, and third trenches are formed through the first and the second structural layers by removing selective portions of the thick structural regions.

The method comprises: generating an electric echo signal indicative of an ultrasonic echo signal returned by a target body by the ultrasonic source signal; determining an envelope signal indicative of an envelope of the electric echo signal; generating a first TOF estimate by processing the electric echo signal; determining an envelope signal portion of the envelope signal based on a non-PSOA hyperparameter; and generating a second TOF estimate by processing the envelope signal portion through PSOA, the second TOF estimate having a measurement accuracy value greater than that of the first TOF estimate. PSOA is optimized based on a PSOA hyperparameter set. The non-PSOA hyperparameter and the PSOA hyperparameter set are selected among a plurality of choices based on the first TOF estimate, so as to obtain the second TOF estimate which has greater accuracy than the first TOF estimate.

  • Patent number: 12014084
    Abstract: A non-volatile memory receives a data read request from a processing core of a plurality of processing cores. The read request is directed to a data partition of a non-volatile memory. The non-volatile memory determines whether to process the read request using read-while-write collision management. When it is determined to process the read request using read-while-write collision management, an address associated with the read request is stored in an address register of a set of registers associated with the processing core. Write operations directed to the data partition are suspended. A read operation associated with the read request is executed while the write operations are suspended and data responsive to the read operation is stored in one or more data registers of the set of registers. The data stored in the one or more data registers of the set of registers is provided to the processing core.

  • Patent number: 12015515
    Abstract: A transmitter circuit receives a PWM input signal and a clock signal. A logic circuit generates a control signal as a function of the clock signal. The control signal is normally set to high, and is periodically set to low for a transmission time interval when an edge is detected in the clock signal. The transmission time interval is shorter than a half clock period of the clock signal. A tri-state transmitter receives the PWM input signal and the control signal, and produces first and a second output signals at first and second transmitter output nodes, respectively. The output signals have a voltage swing between a positive voltage and a reference voltage. An output control circuit is sensitive to the control signal and is coupled to the first and second transmitter output nodes.

    Abstract: A method of operating an electronic converter is provided in which a switching activity of a switching stage of the electronic converter is active or inactive based on a control signal, and the method includes operating the electronic converter, alternatively, in a first or a second mode. In the first mode, the status signal is initially asserted and is de-asserted in response to an amplitude of the input sensing signal failing to reach a first reference threshold value. In the second mode, the status signal is initially de-asserted and an auxiliary power supply signal is periodically varied with a variation period. After a time interval equal to the variation period, a comparison signal is asserted in response to an amplitude of the sensed signal reaching a second reference threshold value. The status signal is asserted based on conditions of the comparison signal and the periodically varying auxiliary power supply signal.
