Abstract: The present disclosure relates to a circuit for testing a random number generator adapted to delivering a series of random bits and comprising at least one test unit configured to detect a defect in the series of random bits, said test circuit being adapted to verifying whether, after the detection of a first defect by the test unit, the number of random bits, generated by the random number generator without the detection of a second defect by said unit test, is smaller than a first threshold.

Abstract: An integrated random signal generation circuit includes two logic gates, the output of each gate coupled to a respective first input of the other gate via assemblies of delay elements. The respective delays introduced by the assemblies of delay elements are adjustable.

Abstract: A system controls aspiration and dispensation of a liquid in a pipette. The system includes a computing device and the pipette. The computing device includes a pipetting module and a first communication interface. The pipetting module defines an operation to perform at the pipette. The first communication interface sends electronic signals to the pipette, the electronic signals defining the operation to perform at the pipette. The pipette includes a sampling tube, a piston assembly, a piston drive mechanism, a second communication interface, and a microprocessor. The piston assembly mounts to the sampling tube and includes a piston rod that fits within the sampling tube. The piston drive mechanism includes a control rod having a surface that contacts the piston assembly. The piston drive mechanism moves the piston rod of the piston assembly within the sampling tube thereby causing regulation of a liquid in the sampling tube.

Abstract: A facility providing image data exchange between client terminals (1) and at least a service terminal (2), via a communications networks. Each client terminal (1) includes data display means (5) and first processing means, configured for placing in a request for accessing an image, intended for the server terminal (2), display characteristics of the client terminal. The server terminal (2) includes a second processing means capable i) of extracting from an request for accessing an image, received from a client terminal, the characteristics of its display means, ii) of establishing a correspondence between the different data types of the image and the display characteristics, and iii) of determining from the display characteristics corresponding to the data types of the image, those which are the closest to the extracted display characteristics so that the image data associated with the type of data corresponding to the determined characteristics are transmitted to the client terminal.
