Abstract: A transmission signal (10a) is frequency modulated (10), and amplified (12) to a specific level and transmitted by an aerial via a filter (14). At this point, the output signal level is regulated by control of the degree of amplification. This control is effected by detection of the amplifier circuit output signal level by a detector (18). The signal level is compared with a reference level produced bya control unit (20) and a reference value generator, using a comparator (24). - The degree of amplification is controlled by an amplifier control circuit (26) on the basis of the comparison result. A keyboard or finger plate (28) is available to adjust the level of the transmission signal, and causes the control unit to activate the reference value generator to produce an appropriate signal. Since the detector properties vary, e.g. due to ambient temp. and that within the equipment, a temp. compensator (30) is incorporated in the detection circuit to ensure that its properties do not vary due to temp. effect.

Abstract: Microwave drying system and method in which arcing is detected by a sudden drop in electric field strength within the drying chamber. An electric signal corresponding to field strength is provided and, in one disclosed embodiment, is compared with a reference signal which varies with changes in field strength which occur more slowly than changes due to arcing. The two signals are compared, and an output signal is provided if the two signal differ by more than a predetermined amount. This permits the sudden drop which accompanies arcing to be distinguished from more gradual changes in the electric field which occur, for example, as moisture is evaporated from the clothing or other articles being dried.

Abstract: A ventilator system (2) comprises different sub-systems, such as a connection system (6), which influence the flow of breathing gas supplied to a patient's respiratory system (8). The flow pattern of the breathing gas is particularly influenced by the connection system (6). In order to compensate for this influence to the greatest possible extent in the generation of breathing gas, the connection system's (6) transfer function is determined before the system is connected to the respiratory system (8). A gas flow with a specific gas flow pattern is generated with great accuracy in a ventilator unit (4). An ensuing gas flow pattern, only influenced by the connection system (6), is measured with great accuracy in a measurement unit (18, 20, 22) in the ventilator unit (4). The transfer function for the connection system (6) can be determined in a control unit (26) from the known, generated gas flow pattern and the measured, ensuing gas flow pattern. The corresponding determination can be made for the respiratory system (8) after a patient has been connected. <IMAGE>
