Abstract: The invention pertains to an imaging device and to a process for controlling the device. The device comprises a power supply (1), matrix means allowing an image to be emitted or sensed, the matrix of the matrix imaging means being scanned at a scanning frequency, the power supply (1) converting a DC input voltage (Dce) into at least one DC output voltage (DCs) allowing the powering of the matrix imaging means (2). The power supply (1) is of chopped type and chops the DC input voltage (Dce) at a chopping frequency dependent on the scanning frequency. In the process for controlling the imaging device described above, a useful image is preceded by an offset image and a correction dependent on the offset image is applied to the useful image.

Abstract: The invention concerns informatics equipment for an actor in a logistic chain of production or processing of products, more specifically of food products.

Abstract: A service platform comprises: (a) a traceability database intended to receive, from computer apparatus of each actor in the logistics chain, an identifier of an operation carried out, an identifier of the operator, information concerning the date the operation was carried out, and an identifier of the operation carried out immediately upstream of or downstream of the given actor; (b) a database, recording (in memory) the rights of access of each actor, to information stored in the respective databases of the other actors; and (c) a routing database, providing the information needed for routing of the information between the actors, depending on data furnished by the traceability database and depending on the right-of-access database.
