摘要:
Nozzle arrangement (10) of a vacuum cleaning device (100) for cleaning a surface (20), comprising: - a nozzle housing (28); - a brush (12) rotatable about a brush axis (14), said brush (12) being provided with flexible microfiber brush elements (16) having tip portions (18) for contacting the surface to be cleaned (20) and picking up dirt and liquid particles (22, 24) from the surface to be cleaned (20) during the rotation of the brush (12); - a drive means for rotating the brush (12); - a single squeegee element (32) for wiping dirt and liquid particles (22, 24) across or off the surface to be cleaned (20) by contacting said surface (20) with its free end (33), wherein said squeegee element (32) extends along a longitudinal direction (48), which is arranged substantially parallel to the brush axis (14), and is attached with its fixed end (33) to the bottom side (30) of the nozzle housing (28) on a side of the brush (12) where the brush elements (16) enter the nozzle housing (28) during the rotation of the brush (12).
摘要:
Disclosed is a semiconductor device (1) for determining NO concentrations in fluids such as exhaled breath. The device (1) typically comprises a pair of electrodes (18) separated from each other to define a channel region (16) in an organic semiconductor (14), a gate structure (10) for controlling said channel region, and a receptor layer (22) at least partially overlapping said channel region, said receptor layer comprising a porphine or phtalocyanine coordination complex including a group III-XII transition metal ion or a lead (Pb) ion for complexing NO. Such a semiconductor device is capable of sensing NO concentrations in the ppb range.
摘要:
A device for performing an action on a surface comprises at least one movably arranged functional body (21, 22), driving means for driving the functional body (21, 22), main safety means for decoupling the driving means from the functional body (21, 22) when a load exerted by the functional body (21, 22) in the direction of the driving means under the influence of resistance forces experienced by the functional body (21, 22) exceeds a predetermined maximum value, and additional safety means (40) which are movably arranged in the vicinity of the functional body (21, 22), and which are capable of exerting loads on the main safety means to different extents in different positions, at a side of the main safety means associated with the functional body (21, 22). The additional safety means may comprise a bar (40) having a non-circular cross-sectional area, which is rotatable about its longitudinal axis (41).
