Patent number: 7090486Abstract: The invention relates to a control system (15) for a burner and a setting-up procedure. The control system (15) controls the air ratio for combustion using the ionisation electrode (16). For calibration, a change is carried out in a first parameter, and the subsequent change in a second parameter is observed. Accurate expected values for the change observed come from stored characteristic data that have been determined in the setting-up procedure, and from taking into account the current combustive content of air and fuel. This allows corrective measures or fault signals to be established.Type: GrantFiled: September 3, 2002Date of Patent: August 15, 2006Assignee: Siemens Building Technologies AGInventor: Rainer Lochschmied

Patent number: 7049987Abstract: In a method for generating a scanning clock signal (S) for scanning an analog signal (Ua) for an analog-to-digital converter (20) operating according to the sigma-delta method, a variable period (T; T*) of the power supply system (PL) is ascertained in time units of a system clock signal (C), and the scanning clock signal (S) is generated by distributing a constant number K of pulses over the ascertained period (T; T*), so that the frequency of the scanning clock signal (S) is an integer multiple of the frequency of the power supply system (PL). The method is essentially able to be carried out by an accumulator unit (4) connected to a counter (3) and makes possible the advantage that during the analog-to-digital conversion a mains hum contained in the analog signal (Ua) is suppressed.Type: GrantFiled: July 26, 2004Date of Patent: May 23, 2006Assignee: Siemens Building Technologies AGInventor: Walter Stoll

Patent number: 7049829Abstract: In a method of determining air humidity, a corrected moisture signal is calculated for a moisture signal (Hi) ascertained from electrical properties of a capacitive moisture measuring element. In a measuring phase (30) with rising relative air humidity (RH), the corrected moisture signal is the current moisture signal (Hi) increased by a correction value, whereas in a measuring phase (31) with falling relative air humidity (RH) the corrected moisture signal is the current moisture signal (Hi) reduced by a correction value. Depending on the respective properties of the moisture measuring element and the required degree of measuring accuracy, the correction value is constant or is taken into consideration in dependence on the relative air humidity RH. This method provides a higher level of measuring accuracy with a moisture sensor equipped with the moisture measuring element.Type: GrantFiled: October 14, 2003Date of Patent: May 23, 2006Assignee: Siemens Building Technology AGInventor: Yves Lüthi

Patent number: 7030630Abstract: In a method of determining air humidity, a capacitive moisture measuring element (2) used in a moisture sensor for calculation operations is modelled by a parallel circuit of an ideal capacitor (C) and an ohmic resistance (Rp). Charging and/or discharging of the capacitive moisture measuring element (2) by way of a first measuring resistor (R1; RA) provides for ascertaining a first time constant or a first period duration of the charging and/or discharging operation, and charging and/or discharging of the moisture measuring element (2) by way of a second measuring resistor (R2; RA//R) provides for ascertaining a second one. The capacitance (C) of the moisture measuring element (2) is then calculated from the two time constants or the two period durations, a value for the moisture level finally being ascertained from the capacitance. This method achieves a higher level of measuring accuracy on the part of the moisture sensor.Type: GrantFiled: October 14, 2003Date of Patent: April 18, 2006Assignee: Siemens Building Technologies AGInventors: Christoph Haas, Yves Lüthi
