    摘要: A low and medium voltage electrical enclosure comprising a supporting structure which defines an internal space delimited by walls forming one or more compartments housing one or more electrical apparatuses. At least one of said walls is provided with one or more venting openings that put into communication said internal space with the outside of said low voltage electrical enclosure and/or one of said compartments with a second compartment. The venting openings are provided with a cover closing a corresponding venting opening in a first—closed—operating condition at first predetermined temperatures and the enclosure is provided with an actuating device adapted to open said cover in a second—open—operating condition at second predetermined temperatures. The actuating device comprises an actuating mechanism having a Shape Memory Alloy-based (SMA-based) actuating element having a first dimension at said first predetermined temperatures reversibly changeable into a second dimension at said second predetermined temperatures, the reversible change of dimension of said SMA-based actuating element from said first dimension to said second dimension determining the reversible movement of said cover from said first—closed—operating condition to said second—open—operating condition, and vice-versa.

At least one of said walls is provided with one or more venting openings that put into communication said internal space with the outside of said low voltage electrical enclosure; the venting openings are provided with a cover closing a corresponding venting opening in a first—closed—operating condition. The enclosure is provided with an actuating device adapted to open said cover in a second—open—operating condition in case of arc fault inside said internal space; said actuating device comprises an actuating mechanism having a Shape Memory Alloy-based (SMA-based) actuating element having a first dimension at first predetermined temperatures reversibly changeable into a second dimension at second predetermined temperatures. The reversible change of dimension of said SMA-based actuating element from said first dimension to said second dimension determines the reversible movement of said cover from said first—closed—operating condition to said second—open—operating condition, and vice-versa.

    摘要: Provided herein is a label structure for tagging a product item. The label structure includes a first graphic pattern having a first number of pixels and printed on a first portion of the label structure; a second graphic pattern having a second number of pixels and printed on a second portion of the label structure, the second graphic pattern forming an optical code readable by an optical decoding device; and shielding means capable of hiding or making visible the first graphic pattern depending on the values taken by a physical quantity to which the label structure is exposed. The first and second graphic patterns can be observed in combination, when the first graphic pattern is made visible by the shielding means.
