摘要： An outdoor enclosure for a video surveillance system comprises: a housing having an outer wall with an opening; an observation bubble disposed over the opening, the housing being adapted for supporting a video surveillance camera; and, first and second fans mounted in the enclosure to establish an air flow pattern when the fans are operating which circulates substantially unidirectionally around the video surveillance camera when the camera is disposed in the bubble, the circulating air flow pattern being substantially free of dead zones inside the bubble and efficiently conducting thermal energy from within the enclosure to the outer wall and to the bubble for subsequent dissipation outside the enclosure. The enclosure can comprise a temperature responsive heater mounted in the circulating air flow pattern adjacent to the fans, downstream from the heater and upstream from the bubble. The fans are substantially transversely aligned within the circulating air flow pattern.

摘要： An EAS tag comprising a tag body having a central region, side wall regions connected to and integral with the central region and flap regions connected to and integral with the side wall regions. The tag body has fold lines at the junctions of the central and side wall regions and at the junctions of the side wall regions and the flap regions. By folding the tag body along these fold lines and, in the course of the folding procedure, inserting a first magnetic element, a substantially closed box-like housing with the first magnetic element loosely housed therein is formed.
