Patent number: 10379173Abstract: A magnetic field sensor generates signal components corresponding to an uncalibrated representation of a sensed magnetic field in a three-dimensional coordinate system. A reader coupled to the magnetic field sensor determines a center offset based on received signal components, adjusts the received signal components based on the determined center offset, and applies Kalman filtering to the adjusted signal components, generating a set of ellipsoid parameters. The reader generates calibrated signal components based on the determined center offset and the generated set of ellipsoid parameters.Type: GrantFiled: March 21, 2016Date of Patent: August 13, 2019Assignee: STMICROELECTRONICS S.R.L.Inventors: Rossella Bassoli, Carlo Crippa

Patent number: 9151011Abstract: A drilling method and device is for the execution of diaphragm walls by cutters, (131, 105, 110) carried by a frame (130) supported by suspension and movers (102). A guide hole (200) is formed as far as the depth specified in the design at the center of the panel to be made. Excavation is started with the introduction into the guide hole (200) of a guide element (101) that is fixed with respect to the tool-holder frame and having geometry such as to copy the guide hole along which it slides during excavation. Excavation is carried out as far as the depth specified in the design. The tool is extracted from the excavation and the excavation is filled with concrete and a panel is formed. The method is repeated so as to form adjacent panels.Type: GrantFiled: July 19, 2011Date of Patent: October 6, 2015Assignee: SOILMEC S.P.A.Inventors: Davide Trevisani, Stefano Trevisani, Maurizio Siepi, Carlo Crippa

Patent number: 5606625Abstract: A digital circuit for controlling the gain of an amplifier stage of a coded signal receiving channel is provided. The circuit includes a peak detector coupled to the input terminal of the receiving channel through a coded signal rectifying circuit and a gain control stage. The gain control stage includes a digital comparator having two input terminals respectively connected to an output terminal of the peak detector and to a memory, and an output terminal coupled to a gain control terminal of the amplifier stage. The address selectable contents of the memory contain predetermined peak values in coded form.Type: GrantFiled: May 26, 1994Date of Patent: February 25, 1997Assignee: SGS-Thomson Microelectronics S.r.l.Inventors: Carlo Dallavalle, Carlo Crippa, Pierangelo Confalonieri

Patent number: 5559687Abstract: A voltage multiplier for relatively high output current has its design output voltage stabilized and rendered independent of process spread, temperature, supply voltage and output current level, by a stabilization loop driving the switch that cyclically connects to ground a charge transfer capacitance of the functional voltage multiplier circuit. The feedback loop comprises an integrating stage, stabilized by creating a low-frequency zero in the transfer function for compensating one of two low-frequency poles of the transfer function of the whole circuit.Type: GrantFiled: June 17, 1994Date of Patent: September 24, 1996Assignee: SGS-Thomson Microelectronics, S.r.l.Inventors: Germano Nicollini, Pierangelo Confalonieri, Carlo Crippa

Patent number: 5287106Abstract: The circuit includes a filter to which an analog signal is applied, a quantizer driven by the filter, a sampler at a desired frequency driven by the quantizer and a PCM encoder driven by the sampler. The quantizer generates a quantize signal according to the received analog signal and further generates a difference signal according to the difference between a quantized signal and the analog signal. A feedback circuit feeds back the difference signal from the quantizer to a stage of the filter so that the overall transfer function from the input of the feedback circuit to the output of the filter is equivalent to a low pass filtering.Type: GrantFiled: April 28, 1988Date of Patent: February 15, 1994Assignee: SGS-Thomson Microelectronics SpAInventors: Daniel Senderowicz, Germano Nicollini, Carlo Crippa, Pierangelo Confalonieri
