Abstract: A holder and a filter system are provided. The holder has: a front wall, a window is formed therein so as to expose the hollow cavity of the holder; a back wall, facing the front wall; a pair of side walls, facing each other and connecting the front wall and the back wall; an opened top portion; and a bottom wall, facing to the top portion and closed so as to define the hollow cavity of the holder. The back wall can be provided with an attachment mechanism. By using the holder and the filter system, an operator may easily determine when to replace the filter cartridge during the operation of the filter system. The holder allows a very good keeping and as well a rapid replacement of the indicator.

Abstract: A system and method for simulating operation of a non-medical tool, having at least one device for detecting the spatial position and movement of a user, a data processing device and at least one display device that displays a virtual processing object. The data of the device for detecting the spatial position and movement of a user are sent to the data processing device, are processed there, and are forwarded to the at least one display device which displays an image of the user or of a part of the user and an image of the tool, the positions and movements of the images being displayed on the basis of the data of the devices for detecting the spatial position and movement of a user relative to the virtual processing object.

Abstract: The invention relates to a method that allows a third party to authenticate a manufacturer's individual product. According to said method, at least one first code that is specific for said individual product is generated and is applied to the product or the packaging thereof by the manufacturer, said first code is stored in a publicly accessible database, the first code is read by the third party and is entered into the database, and the database generates an output based on a comparison between the entered first code and the first codes of all products stored in the database, said output indicating whether the first code is identical to a stored first code and/or whether the first code has been retrieved at an earlier time. Previously known methods of this type offer no sufficiently sure possibility to verify whether the product is an original product or a counterfeit product.

Abstract: The invention relates to a fluid reservoir for a paint spray gun, comprising a cup-shaped receptacle (1), a lid (2) that can be placed thereon (1) and a connecting part (3) which can be formed on the receptacle (1) or on the cover (2) and which is used to secure the fluid reservoir to the paint spray gun. According to the invention, a transition area (12) between the connecting part (3) and the receptacle (1) or the cover is embodied in a flexible manner in order to adjust the inclination of the receptacle (1) or the cover (2) in relation to the central axis (14) of the connecting part (3) in order to improve material guiding, even when the paint spray gun is inclined positions.

Abstract: The invention concerns a virtual painting system for simulating a paint application process and the resulting application of paint to a surface. The system includes a virtual paint applicator device, a position detector to detect the spatial position of the paint applicator device with respect to the surface to be painted, a data processing unit and a display device, wherein the position data of the paint applicator device are routed to the data processing unit, where they are converted into video data for rendering the virtual paint application visible, and which are further routed to the display device, in order to show a visual image of the virtual paint application process on the surface to be painted. This painting system makes possible a quick and, at the same time, realistic virtual representation of painting with a paint spray gun.
