L'invention concerne un dispositif d'éclairage d'une cible, comprenant : - un support (2) présentant une surface de réception de la cible à illuminer, le support incluant une zone (210) d'éclairement de la cible, le support et/ou pour le moins la zone d'éclairement du support étant d'une couleur déterminée caractérisé par un spectre d'absorption déterminé ; - une armature (3) comprenant un groupe lumineux formé d'une pluralité de sources lumineuses. Selon l'invention, chaque source lumineuse émet un spectre lumineux, dit spectre d'émission, choisi, principalement, dans le spectre d'absorption déterminé.

Current transducer (1) for measuring an alternating current in a conductor, the current transducer comprising an inductor (2) having a first connection point (4a) at a first electric potential corresponding to a first measurement voltage Va with respect to ground and a second connection point (4b) at a second electric potential corresponding to a second measurement voltage Vb with respect to ground, and a processing unit (10) connected to the first and second connection points (4a, 4b) configured to convert an induction voltage induced in the inductor by said alternating current into an output signal of the current transducer representing a measurement of the alternating current. The processing unit (10) comprises a first analog-to-digital converter (30a) connected to the first connection point (4a), a second analog-to-digital converter (30b) connected to the second connection point (4b), and a linearity compensation network (20). The linearity compensation network (20) comprises:a voltage divider (21) connected between the first and second connection points (4a, 4b) and having a mid-point (4c) at a mid-point electric potential (φmid) between the first electric potential and the second electric potential,a subtractor (27) connected to an output of the first analog-to-digital converter (30a) and an output of the second analog-to-digital converter (30b), anda mid-point voltage adjustment unit (23) connected to an output of the subtractor or outputs of the first and second analog-to-digital converters (30a, 30b), and configured to adjust the mid-point electric potential (cpmid) based on the output of the subtractor or the outputs of the first and second analog-to-digital converters (30a, 30b) to maintain absolute values of the first and second measurement voltages Va, Vb greater than an error threshold Th for an alternating current with a peak amplitude smaller than a small amplitude current threshold Th₁.

A cleaning device, a cleaning system, and a cleaning assembly, the cleaning device comprising: a machine body, a cleaning assembly, and a heat storage apparatus. The cleaning assembly comprises a wiping cloth mounting frame and a wiping cloth, the wiping cloth mounting frame being connected to the machine body, and the wiping cloth being disposed on the wiping cloth mounting frame. The heat storage apparatus is disposed on the wiping cloth and/or the wiping cloth mounting frame, the heat storage apparatus being thermally connected to the wiping cloth, so as to absorb heat from a heat source when the wiping cloth is being washed, and release heat to the wiping cloth when the wiping cloth is used for performing a cleaning operation. The cleaning device of the present solution can solve the technical problem of a poor cleaning effect caused by an existing cleaning device using room temperature water for cleaning.
