Patent number: 11619688Abstract: A planar Hall sensing element includes a first pair of sensing electrodes mutually opposed in a first direction across the sensing element and a second pair of sensing electrodes mutually opposed in a second direction across the sensing element, with the second direction orthogonal to the first direction. A first pair of bias electrodes is mutually opposed in a third direction and a second pair mutually opposed in a fourth direction across the sensing element, the fourth direction orthogonal to the third direction. The third and fourth directions are rotated 45° with respect to the first and second directions so each sensing electrode is arranged between a bias electrode of the first pair and second pair. A DC bias current is supplied between the first and second pairs of bias electrodes. First and second Hall voltages are sensed at the first and second pairs of sensing electrodes.Type: GrantFiled: September 2, 2021Date of Patent: April 4, 2023Assignee: STMICROELECTRONICS S.R.L.Inventors: Marco Crescentini, Michele Biondi, Marco Tartagni, Aldo Romani, Roberto Antonio Canegallo

Patent number: 10693376Abstract: An electronic converter has first and second input terminals, first and second output terminals, a current regulator circuit arranged between the first input terminal and an intermediate node, and input capacitor arranged between the intermediate node and the second input terminal, and an output capacitor. A control circuit block is configured to sense an input voltage, compare the regulated voltage to a reference value and generate a first signal, compare the input voltage to a lower threshold and an upper threshold and generate a second signal, switch the electronic converter between an active mode and an idle mode as a function of the first signal, and switch the electronic converter between a recharge phase and a switching phase as a function of the second signal when the electronic converter is in the active mode.Type: GrantFiled: August 27, 2019Date of Patent: June 23, 2020Assignee: STMicroelectronics S.r.l.Inventors: Matteo Pizzotti, Michele Dini, Aldo Romani, Rita Zappa, Stefano Corbani, Giulio Ricotti

Patent number: 9442055Abstract: Method for measuring the hardness of agricultural products includes: implementing a test program suitable for identifying and selecting one or more indices (S3, S4) which can be measured with a non-destructive test on a respective product/fruit, correlated with the hardness (Du) of the same product/fruit, measured by a respective penetration test; and calculating the coefficients that define the straight line representative of the linear correlation between said indices and the hardness for the respective product. The method is implemented with the operations of: applying on the product a dynamic force, preferably of impulsive type; detecting the mechanical reaction through at least a piezoelectric transducer capable of generating an electric signal based on the application or transmission of said dynamic force through the respective kiwi fruit; and analyzing said electric signal relative to the fruit.Type: GrantFiled: March 22, 2012Date of Patent: September 13, 2016Assignee: UNITEC S.P.A.Inventors: Luca Benedetti, Enrico Macrelli, Aldo Romani, Rudi Paolo Paganelli
