The present invention concerns an auto-close door for closing an area (3) at least partially defined by a frame, said auto-close door comprising: A) A motorized driving mechanism (10) suitable for moving a leading edge (1L) of a shutter (1) in a first direction (a) to close said area defined within said frame and in a second direction (β) to open said area; B) Wave detection cells (5) suitable for detecting the presence of an obstacle within the area defined by the frame; and/or C) In addition or alternatively, an impact detector (6) suitable for detecting an impacting event with a leading edge of the shutter, D) A processing unit (CPU) programmed to carry out the following operations: a) Upon opening the area a first time by moving the leading edge of the shutter in said second direction (β), maintain the area open for an opening time (t1), after which b) close the shutter, c) Record whether an obstacle and/or an impacting event is detected by the wave detector or the impact detector, upon closing the shutter; d) Count the number (n), of obstacles and/or impacting events detected during a number (N), of repetitions of the cycle defined by steps (a) to (c), and if n/N>v.sub.ref,1, wherein, v.sub.ref,1, is a first control ratio, then the opening time (t1), is prolonged to a time, t2=t1+Δt2, wherein Δt2>0; (e) Repeat steps (a) to (d) with the values t1 or t2 determined in step (d).

An optoelectronic component includes a carrier, and a light source arranged on a surface of the carrier, said light source including at least one luminous surface formed by at least one light-emitting diode, wherein a transparent converter-free spacer is arranged on the luminous surface such that a distance is formed between the luminous surface and a spacer surface of the spacer facing away from the luminous surface, and wherein the light source is potted by a potting compound such that the spacer surface is formed extending flush with a potting compound surface facing away from the surface of the carrier and a surface formed by a spacer surface and the potting compound surface is plane.

Embodiments of the invention provide a header for enclosing a counterbalance assembly for use with an overhead door assembly. The header comprises a top surface, a rear surface coupled to a rear end of the top surface, a bottom surface coupled to a bottom end of the rear surface, and at least one reinforcement member disposed rearward of the counterbalance assembly and forward of the rear surface. The at least one reinforcement member provides necessary reinforcement to the header while allowing for a vertical height of the header to be minimized.

An easily displaceable sliding door configured to be installed in an opening of a partition wall includes a shutter having an upper edge, a carriage secured to the shutter at the upper edge, a guiding member configured to be secured to the opening substantially parallel to the upper edge to allow sliding of the carriage, a magnetic unit having a lower portion integral with the shutter and an upper portion configured to be secured to the guiding member to reduce the weight force of the shutter to facilitate displacement, wherein the upper and a lower portions are separated by an air gap. The guiding member is of linear type and includes a straight cavity with an upper wall for supporting the upper portion of the magnetic unit, the upper edge and the a carriage being entirely embedded in the cavity to be hidden from external view.
