摘要： The invention relates to an overvoltage arrester system (1) for protecting an electrical installation (4) from an overvoltage or impermissible amount of energy, comprising a first metal oxide arrester (6) in a first current path (10) and a second metal oxide arrester (8) in a second current path (12) connected in parallel with the first current path (10). The problem addressed by the invention is that of said overvoltage arrester system being suitable for arresting especially high amounts of energy, in particular from pulsed energy inputs, while at the same time being especially fail-safe. This problem is solved in that in a current range, a voltage/current characteristic curve (18) of the first metal oxide arrester (6) has a lower voltage than a voltage/current characteristic curve (20) of the second metal oxide arrester (8) at the same current, and the first current path (10) has a switch (14).

摘要： Monitoring of high-lift systems (200) for aircraft (100). In one configuration, a method for monitoring a high-lift system (200) includes monitoring a first current draw (I1, I2, I3 or I4) of a first drive station (201, 202, 203 or 204) of the high-lift system (200), and monitoring a second current draw (I1, I2, I3 or I4) of a second drive station (201, 202, 203 or 204) of the high-lift system (200). The method further includes comparing the first current draw and the second current draw to determine if a differential between the first current draw and the second current draw exceeds a threshold, and generating a failure signal if the differential between the first current draw and the second current draw exceeds the threshold.

摘要： Signal coincidence detection circuits and methods implemented in such circuits are disclosed. An example signal coincidence detection circuit includes a first differential transistor pair, a second differential transistor pair coupled with the first differential transistor pair and a third differential transistor pair coupled with the first differential transistor pair in parallel with the second differential transistor pair. The circuit also includes a first input signal terminal coupled with the first, second and third differential transistor pairs, wherein, in operation, the first input signal terminal receives a first input signal that is communicated to the first, second and third differential transistor pairs. The circuit further includes a second input signal terminal coupled with the first, second and third differential transistor pairs, wherein, in operation, the second input signal terminal receives a second input signal that is communicated to the first, second and third differential transistor pairs. The circuit additionally includes a current source coupled with the first differential transistor pair, where, in operation, a plurality of currents of the second and third differential transistor pairs are combined such that the combined currents indicate whether or not coincidence between the first and second input signals exists.

摘要： A digital loss-of-signal ("LOS") detector comprises a trough circuit(20) and a smearing circuit(30). The trough circuit generates a logic output whenever an incoming communication signal is within a predefined voltage range. The output of the trough circuit(20) is applied to the smearing circuit(30), which will generate an LOS output whenever the output of the trough circuit(20) remains at a given logic level for a predetermined length of time. A state machine(110) can be coupled to the output of the smearing circuit(30), to the trough circuit(20) and to the clock signal, the state machine(110) generating the LOS indication if the output from the smearing circuit(30) remains at a logic level for at least a predetermined number of clock cycles. The LOS detector of both embodiments can respond very quickly to a loss of the signal and can also be constructed as a single integrated circuit.
