  • Patent number: 10935152
    Abstract: A valve for switching of media, such as liquids or gases, is opened, closed or put into an intermediate state by at least one actuator produced from a shape memory alloy. The at least one actuator, as a function of whether electricity is applied to it, acts on at least one valve ball or a valve plunger accommodated in a core element, so that the through-flow of a medium through a fluid part below the core element, with a media-tight membrane interposed between, is opened, interrupted or partially opened in regulated or controlled manner. The core element is produced from a mechanically rigid and thermally well-conductive material, has electrical conductor tracks for electrical connection of the actuator to a supply of electricity on the top side, as well as multiple threaded through-holes for underside connection with the fluid part and the membrane and/or for top-side connection with the actuator.
    Type: Grant

  • Patent number: 9660167
    Abstract: A thermoelectric system includes a plurality of thermocouples that are each formed of two thermocouple limbs that include different thermoelectrically active materials. The thermocouple limbs are connected electrically in series and thermally in parallel. The thermodynamic system also includes a flexible and electrically insulating layer formed of a matrix having n rows of thermocouple limbs. The thermocouple limbs form columns having approximately equal widths. Each pair of adjacent thermocouple limbs has a contact region located on a straight fold line above one another in the column direction. The matrix is wound parallel to the rows on top of one another to form a flat strip. The matrix is then folded along the fold lines in the manner of a concertina with elevations and depressions equidistant to one another.
