Abstract: An electronic device including a wave transmitter covering a determined spatial sensing field, and a wave receiver for controlling an automatic device; a radiating antenna including a waveguide having lateral faces and slots arranged on one of the lateral faces, wherein the slots radiate in planes substantially perpendicular to a longitudinal direction of the waveguide, and wherein the wave transmitter and the wave receiver are arranged at one end of the waveguide; a matched load arranged at an opposite end of the wave guide; substantially identical reflectors arranged over substantially the whole length of the waveguide, wherein the reflectors extend essentially symmetrically with respect to longitudinal plane of symmetry of the waveguide and making a predetermined angle with one another, and wherein the waveguide and the reflectors are composed of at least one piece.

Abstract: A device comprising an element (1) serving as a housing and a mounting frame for an apparatus and a suspending element (2), the latter comprising a means (5) suitable for working in conjunction with a complementary means (3) which is integral with the housing (1) so as to form a pivoting coupling; the device also includes adjustable means of spacing (4,5,6) integral with either one of elements (1,2) of the device, said spacing means being designed to work together with a surface of the other element in order to hold the housing (1) in an adjustable predetermined angular position. The spacing means comprise, for example, a means (5) integral with one of elements (1,2) and formed with a rib (4) designed to work together with any one of several grooves (7) formed in the other element.
