Publication number: 20230367733Abstract: A method of operating a plurality of driving units for powering electronic units is described. The method includes interchanging a data frame including a bit sequence, between a master control unit and at least one of a plurality of driving units at slave nodes. The method includes applying an ID field for addressing at least one driving unit, and applying a data field comprising information and/or instructions regarding the status of the electronic units. Applying the ID field comprises indicating the driving unit address using a first bit sub-string comprising N bits, allowing the master control unit to identify whether data should be received or transmitted, performing a data length decoding step, and adding a further bit string to the data field including information for carrying out an action by the driving unit.Type: ApplicationFiled: May 10, 2023Publication date: November 16, 2023Inventors: Kevin BERLIT, Jorgen STURM

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
