    • A communication system for safe wireless control of an manoeuvrable object (3), comprising a control unit (1) having means for operating the object and receiving means for wireless information, and a portable operating unit (2) having sending means for wireless information, where said information is divided in time slots (t s ), each containing a data package (21). The receiving means comprises detecting means for detecting in a time part (t p ) of a time slot the presence of said data package and calculating means for calculating upon a reception failure the number of time parts having no presence of said data package following a time slot with presence of said data package. The control unit exercises a control command when a data package with a correct information has been received within a number of time parts just exceeding a full time slot.

    • A method for the signal processing of capacitive measurement scales intended for the measurement of lengths or angles, consisting of two parts that can move relative to each other provided with electrodes that together form condensers, the magnitudes of which are variable and depend on the relative position as specified by a sinusoidal relationship (x c ) between the two parts that can move relative to each other, whereby the first part has n electrodes evenly distributed over one measurement period and the second part has one electrode per measurement period, and that the electrodes in the first part are fed with n alternating voltages whereby the time displacements of the said alternating voltages relative to each other are (Fig I), where t 0 is the length of the period of n the said alternating voltage, whereby the electrode of the second mobile part captures in a capacitive manner a signal that is composed of one or several of the said alternating voltages and where the amplitude composition of the composite signal depends on the relative position (x) between the two parts. All n signal contributions to the said amplitude composite are measured and stored separately for each one of the n samplings.
