    摘要: A rotary button system (100; 300) for use in a domestic apparatus, comprising: a ferromagnetic plate (110; 310); a button (120) removably mountable at a predefined first distance (dm) from said ferromagnetic plate (110) on a first side of said plate, and rotatable about a virtual rotation axis (105) substantially perpendicular to said plate, and comprising a permanent magnet (122) magnetised in a direction (X, Y) perpendicular to said rotation axis (105); and a magnetic sensor device (130) mounted at a predefined second distance (ds) from said ferromagnetic plate (110) on a second side of said plate opposite the first side, and comprising one or more magnetic sensors for measuring one or more magnetic field components or field gradients, and configured for determining an angular position (a) of the rotary button (120) based on said one or more field components and/or field gradients.

    摘要: A communication system (400) comprising: a digital serial bus (495), and a master device (490) and at least one slave device (410) connected to said bus; wherein the master and the slave(s) are adapted to communicate according to a predefined communication protocol; wherein the master is adapted for transmitting a continuous bitstream in the form of a plurality of frames, each frame comprising one or more words, each word having a constant time duration, the first word (SOF) of each frame being a unique word transmitted by the master for indicating the start of a frame; one or more bits (Sr) of each word being transmitted by the master as a dominant bit; a non-dominant bit, for allowing the at least one slave to overwrite; the at least one slave adapted for overwriting in the continuous bitstream some non-dominant bits to transmit data in a quasi-synchronous manner.
