    • An electrical switch, such as an automotive power window up/down switch, has an electrically conductive dual armature that is normally magnetically held in coupled engagement with a sheet magnet. The dual armature, a rectangular piece of metal, has first and second free ends. If a user applied force acts on the first free end of the dual armature, then the first free end breaks away from the sheet magnet and travels into first electrical contacts that are normally spaced from the dual armature, and the second free end functions as a fulcrum for the dual armature. Conversely, if a user applied force acts on the second free end, then the second free end breaks away from the sheet magnet and travels into second electrical contacts that are normally spaced from the dual armature, and the first free end functions as a fulcrum for the dual armature. Preferably, there is a physical barrier that prevents simultaneous actuation of the two switching functions.
    • 诸如汽车电动车窗上/下开关的电气开关具有通常磁性地保持与片状磁体联接的导电双电枢。 双电枢,一个矩形的金属片,具有第一和第二自由端。 如果用户施加的力作用在双电枢的第一自由端上,则第一自由端脱离片状磁体并且行进到通常与双电枢间隔开的第一电接触,并且第二自由端用作 双电枢支点。 相反,如果用户施加的力作用在第二自由端上,则第二自由端脱离片状磁体并且行进到通常与双电枢间隔开的第二电触点,并且第一自由端用作支点 双电枢。 优选地,存在防止两个切换功能的同时致动的物理屏障。

    • A wound dressing that efficiently absorbs fluid from fluid exuding wounds and can easily be released from the wound without disrupting the wound surface and a process for its manufacture is provided. The dressing comprises a layer of film bonded to a fibrous absorbent web containing a mixture of a particulate superabsorbent and a hydrocolloid. The fibrous absorbent web has a glazed exposed surface wherein the fibers comprising the glazed exposed surface are substantially fused to each other. The glazed exposed surface has a multiplicity of particles comprising a mixture of an adhesive and a hydrocolloid distributed throughout and adherent to the surface. Preferably about 25% to about 50% of the surface is left uncovered by particles comprising the adhesive and the hydrocolloid to enable more efficient transfer of wound exudate into the fibrous absorbent web while the hydrocolloid contained in the particles of adhesive facilitates release of the dressing from the wound without disrupting the surface. A selvage encompasses the wound dressing, with the selvage comprising fibers of the fibrous absorbent web that are substantially fused to each other and to the layer of film bonded to the fibrous absorbent web.
    • 一种伤口敷料,其有效地从流体渗出的伤口吸收流体,并且可以容易地从伤口释放而不破坏伤口表面,并提供其制造方法。 敷料包括粘合到纤维吸收性纤维网上的膜层,其含有颗粒状超吸收剂和水胶体的混合物。 纤维吸收性纤维网具有釉面的暴露表面,其中包含釉面暴露表面的纤维基本上彼此熔合。 釉面暴露的表面具有多个颗粒,其包含粘合剂和水胶体的混合物,其分布在整个表面并附着在表面上。 优选地,约25%至约50%的表面被包含粘合剂和水胶体的颗粒覆盖,使得能够更有效地将伤口渗出物转移到纤维吸收性纤维网中,同时包含在粘合剂颗粒中的水胶体促进了敷料的释放 伤口不会破坏表面。 刀片包括伤口敷料,其中包括纤维状吸收性纤维网的纤维基本上彼此熔合,并且粘合到纤维状吸收性纤维网上的膜层。
