Abstract: An electric bicycle that has a communication system, including at least one electronic processing module for processing information for the rider of the electric bicycle, and at least one signal device for providing the processed information to the rider. To reduce safety risks due to the rider being distracted by his/her surroundings while riding the electric bicycle and to increase riding comfort, the at least one signal device is designed to output the information as a tactile, optical, and/or acoustic signal emitted by the electric bicycle in order to spontaneously influence the rider.

Abstract: A beverage machine, in particular a coffee machine, prepares a beverage using water supplied via a fixed water connection to a hydraulic part arranged in the beverage machine and outputs the beverage at an outlet of the beverage machine. Maintenance is simplified by the fact that the beverage machine is provided with a cartridge holder which is accessible from the outside and into which a cartridge can be inserted in an exchangeable manner, the cartridge includes a cartridge connection on the inlet side and a cartridge connection on the outlet side, via which, in the inserted state of the cartridge, water supplied to the beverage machine via the fixed water connection flows through the cartridge and is thereby filtered and/or enriched with additives.

Abstract: The invention relates to a particularly reliable sliding door construction for platforms, by means of which a passenger area of platforms may be separated from a track area when closed, preventing entry to an arriving train and permitting access to the arriving train in an open state, comprising stationary regions and sliding doors, both the stationary regions and the sliding doors having a height of 1-2 m above the floor level of the passenger region above which no separation of passenger region and track region is arranged. The construction is characterized in that the sliding doors have a self-supporting embodiment and are guided to move in or on the stationary regions with provision of an upper and lower guide and one guide is embodied as a roller guide or ball bearing linear guide and one guide is embodied as a slide guide or roller guide.

Abstract: A membrane for a cover for closing a container having the general form of a cylinder and being compressible in the direction of the axis of the cylinder. The membrane comprises two mutually parallel, generally flat parts arranged to move axially in relation to each other guided in the movement by guiding elements; resilient element arranged to generate a counterforce between the flat parts during compression of the membrane in the direction of the axis; at least a first and a second electrical contact device operated by the axial movement between the circular parts, the combined electrical settings of which contact devices will carry information about the compressions and decompressions of the membrane and elements for presenting the settings to the outside of the membrane. A cover comprising such a membrane and use thereof are also described.
