Abstract: A method for detecting the lock-in of a loop that synchronizes an internal clock on the transmission of value pairs provided by a demodulator. According to the method, a module of a vector that has as components the values of one of the value pairs is calculated, and the module is compared with a threshold that is smaller than a theoretical module. The locked-in condition is determined according to the ratio of the number of modules found to be greater than or smaller than the threshold to the total number of modules. In one preferred method, the threshold is incremented by a first value if the module is greater than the threshold and is decremented by a second value if the module is less than the threshold. A lock-in detection circuit for detecting the lock-in of a loop is also provided. A calculation circuit calculates a module of a vector that has as components the values of one of the value pairs. A register stores a threshold and a comparator compares the stored threshold with the calculated module. A modification circuit modifies the stored threshold based on the comparison result, and an analysis circuit analyzes the stored threshold to determine the locked-in condition.

Abstract: The industrial installation comprises an active zone (III) with which there are associated means for measurement and for command and a control position (I) separated from the active zone. Means for measurement, for control and for command (15) located in the active zone are supplied with luminous radiations, from the control position, through an optical fibre (8) joining the active zone to the control position. Radiation having a broad spectral band is emitted in the fiber (8) from the control position (I) and then divided in order to obtain unitary radiations for supplying each of the means (15).

Abstract: Being given the number among P of a data, an attempt is made to find the number among N of said data in a group of N data incorporating P selected data. The sequence numbers of these P data appear in a register having N locations and the sequence number of the chosen data among P appears in a second register with P locations. The locations of the second register are connected to the rows of a switching circuit, each of these rows having N cells, which connect the input of one cell to the following cell of the same rank or to the following cell of the lower rank, as a function of the content of the corresponding location of the first register. Thus, at the outputs of the columns there are signals, whereof only one is at a level different from the others and corresponding to the number j among N of the chosen data.
