Abstract: A portable stable low-mass microwave radiometer for measuring microwaves in the spectral range between 1 and 300 GHz includes at least one patch array antenna and connected suitable electronics with radio-frequency components and signal processing components, allowing more stable and more accurate measurements of brightness temperature while in particular mounted on an unmanned aerial vehicle. A patch array antenna includes at least one patch array with a patch substrate layer of a dielectric material with a pattern of an even number of printed patches on a front side is printed, while printed patches are connected via inset-feds to striplines. Connector lines are connected to the striplines to be led from a backside of the patch substrate layer to and through a ground conductor layer, which is fixed to the backside of the patch substrate layer in a defined distance forming an air gap between both layer by multiple spacers.

Abstract: A portable urination weight measurement device comprising: a holding unit for releasably holding a container, and a handle comprising a weight measurement unit coupled to the holding unit so as to allow the measure of a weight exerted on the holding unit; and a toilet flushable container having: a rim having a fold at a front side of the opening and a fold at a back side of the opening, each fold forming at rest an angle of less than 20°, and a collar secured to the rim and comprising at least one fold at the front side of the opening forming at rest an angle of less than 20°, the collar being of a rigidity such that increasing the angle of the collar fold to 180° increases the angle of the rim fold at the back of the opening to from 50 to 90°.

Abstract: A chuck for a machine tool having a rotation spindle with a main axis of rotation. The chuck comprises a base plate, a first rotatable plate eccentrically mounted on the base plate, a second rotatable plate eccentrically mounted on the first rotatable plate, balancing means for aligning a principal axis of inertia of the chuck with the main axis of rotation and a holding mechanism. The chuck is provided with an actuating mechanism for angularly displacing the first rotatable plate around a first rotation axis over a first angle of rotation and/or the second rotatable plate around a second rotation axis over a second angle of rotation such that the position of the object with respect to the main axis of rotation can be altered.

Abstract: Disclosed is a method for predicting tire performance in which a tire model, which comprises a tread pattern capable of imparting deformation by means of ground contact and/or transfer, and a snow model, in which a snow-covered road surface that comes into contact with the tire model is represented, are used to predict tire performance on the snow-covered road surface on the basis of physical quantities that occur in at least either of the tire model and the snow model. The snow model is modeled as an elasto-plastic body or an elastic body, the nonlinearity of the volume compression property of snow is represented by the relationship between the density or volume strain of the snow and the pressure of the snow, and the shear property of the snow is represented by the relationship between the yield stress of the snow and the pressure of the snow.

Abstract: The present invention is a generally parallelepiped shaped container including generally parallel opposite lateral side panels, generally parallel opposite longitudinal side panels and a generally flat bottom panel. A first generally flat top panel is provided near the first lateral side panel and a second generally flat top panel is provided near the second lateral side panel, the first and second top panels being interconnected to form a generally continuous top portion of the container. A dispensing neck extends upwardly from the first top panel and a cover member is removably positioned over the open end of the dispensing neck. The shape of the container and the cover member are such that the height of the cover member, when on the dispensing neck is less than the height of the second top panel so that the containers may be stacked one above the other without applying pressure to either the cover member or the dispensing neck.

Abstract: Process for the local removal of a coating (2), consisting of at least one metallic layer and/or at least one metal-oxide layer, applied on a translucent or transparent substrate (1) made of natural or synthetic glass or of transparent plastic, characterised in that, by means of a solid-state pulse laser (4) or at least one pulsed laser diode, a pulsed laser beam (3) whose pulse is inferior to the 30 ns and whose wave length(s) is/are comprised between 10 micrometers and 360 nanometers is directed onto the coating (2) to those spots where the latter has to be removed, whereby the applied wave lengths are such that the absorption of the substrate (1) and of the coating (2) as a whole is less than 30%.
