Patent number: 11476784Abstract: Methods and apparatus for open loop startup of a three-phase motor that reduces acoustic noise. During rotor alignment of the motor, there is a maximum level for a phase current to the motor. After the rotor alignment, open loop motor startup is performed during which the phase current has a first slope. At a selected time, such as when a frequency of the phase current reaches a first threshold, the phase current transitions to a second slope.Type: GrantFiled: July 9, 2021Date of Patent: October 18, 2022Assignee: Allegro MicroSystems, LLCInventors: Masahira Kurihara, Dmytro Sakharov, Anton Babushkin

Patent number: 11102031Abstract: The present invention relates to a receiver circuit for processing an incoming bit stream from a bus system. The circuit comprises an analog interface for converting the analog signal to a digital input data stream. The interface comprises an analog filter and a switch to process the analog signal before generating the digital input data stream using the filter if, and only if, a selection criterion controlling the switch is met. The circuit comprises a frame decoding unit for decoding a data frame encoded in the digital input data stream in accordance with a CAN protocol, and a frame processing unit that comprises a flexible data rate detector and a recessive bit counter for counting consecutive recessive bits after detecting the flexible data rate frame. The selection criterion is satisfied when the flexible data rate frame is detected and unsatisfied when the recessive bit counter reaches a predetermined number.Type: GrantFiled: May 28, 2019Date of Patent: August 24, 2021Assignee: MELEXIS TECHNOLOGIES NVInventors: Martin Bölter, Thomas Freitag, Jörgen Sturm, Anton Babushkin

Patent number: 10326583Abstract: A circuit for receiving and processing a bit stream obtained from an electronic communication bus-system comprises a bit stream processor and bit sampling of the bit stream to provide a sampled output signal. The circuit comprises a frame decoder for decoding a data frame encoded in the sampled output signal, and a clock signal generator for generating a first clock signal for the bit stream processor. The circuit comprises a clock signal downsampler for generating a second clock signal having a lower frequency than the first clock signal, in which the second clock signal is based on a co-occurrence of a clock pulse in the first clock signal and the emission of a bit in the sampled output signal. The bit stream processor is adapted for synchronizing the first clock signal to an external protocol timing of the incoming bit stream.Type: GrantFiled: May 16, 2018Date of Patent: June 18, 2019Assignee: MELEXIS TECHNOLOGIES NVInventors: Jörgen Sturm, Thomas Freitag, Martin Bölter, Anton Babushkin

Publication number: 20110274563Abstract: A dosing pump comprises an inlet for a solvent, an injection device for an additive, a reciprocating main piston for mixing the solvent with the additive during a suction stroke and for discharging the mixture from an outlet in an evacuation stroke. A divider substantially perpendicular to a rod connected to the main piston separates a main piston housing from a switching device for controlling a main piston stroke direction. The switching device comprises two inlet rotary valve assemblies that are disposed externally to a corresponding inlet aperture bored in the divider when in an opened state and are rotatable about an axis substantially perpendicular to the axis of the main piston. Each of the valve assemblies alternately opens and occludes a corresponding inlet aperture so that solvent flowing through a first inlet aperture performs a suction stroke and solvent flowing through a second inlet aperture performs an evacuation stroke.Type: ApplicationFiled: January 14, 2010Publication date: November 10, 2011Applicant: Tefen Manufacture & Marketing Plastic Products 1990 Ltd.Inventors: Lior Man, Anton Babushkin

The insert receiving pocket has a longitudinally extending inner wall, a rear wall adjacent the inner wall and a lower wall adjacent the inner wall and the rear wall. A front end of the lower wall protrudes forwardly with respect to a central portion of the insert holder. A front protrusion rises upwardly from the lower wall and extends inwardly and rearwardly from a periphery of the insert holder. The front protrusion has a front surface perpendicular to the lower wall. A groove formed in the bottom surface of the cutting insert has a distal side wall perpendicular to the bottom surface.Type: GrantFiled: July 5, 2002Date of Patent: January 11, 2005Assignee: Iscar, Ltd.Inventors: Rafael Morgulis, Anton Babushkin
