Abstract: An aircraft turbomachine (100) comprising a first channel (200) putting into communication the high-pressure compressor (30) and a high-pressure turbine (50), a second channel (400) putting into communication the high-pressure compressor and a low-pressure turbine (60), the first channel being equipped with a valve (600), a third channel (700) being in selective communication with the first channel via the valve, the third channel being in communication with the low-pressure turbine, the valve having a first configuration in which air circulation in the first channel is allowed and prohibited in the third channel, and a second configuration in which air circulation of the first channel is diverted to the third channel, a control device (800) being configured to determine an air pressure of the low-pressure turbine and command the valve to cause it to transition from the first configuration to the second configuration depending on the determined pressure.

Abstract: A bar code arrangement allows determining positions along an axis. The bar code arrangement includes a plurality of bar code symbols, each having start and stop end characters and encoded data therebetween. The symbols are positioned in a column along the axis and are so oriented that each bar of the symbols is parallel to the axis and that two consecutive bar code symbols have different orientations, one being rotated 180° relative to the other. Scanning the bar code symbol corresponding to a particular position among the plurality of bar code symbols in the column allows identification of the particular position along the axis. A symbol scan is considered successful when two different characters are found in a symbol scan. In the form of a ribbon, this bar code arrangement is suitable to correctly detect a liquid level on a bottle of liquid.
