  • Patent number: 10487481
    Abstract: In the case of a sanitary outflow part (1), it is provided that, between an inlet opening (2) and an outlet opening (3), in a flow path (4) which leads through a jet regulator unit (5), a secondary outlet (7) branches off downstream of the jet regulator unit (5). This secondary outlet leads to an additional secondary outlet opening (8) such that water entering via the inlet opening (2) emerges to the secondary outlet opening (8) at least when the outlet opening (3) of the sanitary outflow part (1) is closed off.

  • Patent number: 9421375
    Abstract: A tissue stimulator including a sensing unit, wherein the sensing unit includes an A/D converter that samples an analog signal using a sampling clock and converts the analog signal into a digital signal. The tissue stimulator includes a digital filter with an input, wherein the input is connected to an output of the A/D converter. Using a filter clock, the digital filter filters the digital signal, and wherein the filter clock is a multiple of the sampling clock for a specific period of time T.

  • Publication number: 20150030945
    Abstract: A fuel cell system is provided, including a fuel cell stack with a plurality of cathodes (30) and anodes (34), wherein an oxidizing gas containing oxygen is feedable to the stack on the cathode side and a fuel gas is feedable to the stack on the anode side, and a reformer for generating the fuel gas from a fuel. The fuel cell stack includes a catalytically active material (42) which is arranged in the anode-side regions such that the fuel gas flows through the material upstream of the anode (34), wherein the catalytically active material catalyzes the reaction of carbon monoxide and water to carbon dioxide and hydrogen.
