Method for determining segment times of a sensor wheel of an iternal combustion engine
A method for determining segment times of a sensor wheel of an internal combustion engine, the sensor wheel being non-rotatably connected to a crankshaft of the internal combustion engine, marks being situated along the circumference of the sensor wheel, and the crankshaft of the internal combustion engine covering predetermined angle ranges during the segment times. Tooth times are determined as time intervals between two marks of the sensor wheel; a low-pass filtering is applied to the determined tooth times, and filtered tooth times are determined as a result of the low-pass filtering.

Method of opening a mine door leaf
A method of opening a mine door leaf installed in a mine passageway having a high pressure zone and a low pressure zone. The method includes the steps of operating a variable-throw crank mechanism in a first configuration having a first crank length to apply a first force to the mine door leaf to move it at a first speed, operating the variable-throw crank mechanism in a second configuration having a second crank length less than the first crank length to apply a second force greater than the first force to the mine door leaf to move it at a second speed slower than the first speed, and using a resistance pressure associated with the high and low pressure zones in the mine passageway to convert the variable-throw crank mechanism from the first configuration to the second configuration..
