Abstract: A counting device including a wall that delimits an internal space; an object counter that is positioned in the internal space and includes a measuring lens, which optically delimits a detection zone outside the counting device. The wall of the counting device includes an aperture positioned in front of, preferably centered relative to, the measuring lens, the measuring lens and the aperture being arranged to transmit to the counter a flux emitted by the objects present in the detection zone.

Abstract: The invention concerns a traffic detector (200) comprising: a hermetically closed tube (202); the said tube (202) delimiting at least one chamber (218), each chamber (218) extending from one of the ends of the said tube (202), for each chamber (218), a piezoelectric sensor placed at the corresponding end of the tube (202) and suitable for transforming the shock waves received into an electrical signal; the traffic detector (200) being characterised in that it comprises an elastic band (204) and fixing devices (208, 210) intended to keep the said elastic band (204) tensioned between the ends of the said tube (202).

Abstract: The invention relates to a device (100) for detecting the passing of individuals in the form of a mat including: a printed circuit board (104), one of the surfaces which supports a plurality of contactors designed to change state under the pressure exerted by a foot or a wheel, and at least one of the surfaces of which supports at least one electronic component (112) not subject to any pressure from said foot: and for the or each surface supporting at least one electronic component (112), a protective layer (106) attached to said surface and incompressible under the weight of individuals/trolleys, the or each electronic component (112) being recessed in a hole (110) in said incompressible protective layer (106).

Abstract: A device for counting and determining the direction of passage of living beings. A first cell delivers an electrical signal representing the passage of a living being. A second pryoelectric cell delivers a second electrical signal. A processing unit analyzes the signals and determines the number of living beings moving past and their direction of movement.

Abstract: The invention concerns an electronic housing (100) intended to be fixed under a cover of a manhole, the cover comprising at least a first fixing means and a through cavity, the electronic housing (100) comprising: a shell (102) having a top face, for the or each first fixing means, a second fixing means intended to cooperate with said first fixing means in order to fix said shell (102) under the cover, electronic components comprising a wireless communication module, and a control module intended to change said wireless communication module from an inactive mode to an active mode, said control module comprising a sensor able to react in the presence of a wakeup device, projecting with respect to said top face and intended to be housed in said cavity.
