  • Patent number: 12675666
    Abstract: A limit value detection device for multiple detection of a limit value event has a catch mechanism manufactured using microstructuring technology, having a first and a second catch element, each having a plurality of catches, a pawl configured to engage in a catch intermediate space between two adjacent catches of the first catch element, the first catch element being movable relative to the pawl in a freewheeling direction and movement thereof relative to the pawl in a blocking direction being blockable by the pawl, and an actuating device configured to move the first catch element and the pawl relative to each other in a catch-by-catch manner in the freewheeling direction. The first and second catch elements together form a counting unit in which the counter status for indicating the detected limit value events is determined based on the position of the two catch elements relative to each other.

  • Patent number: 10885422
    Abstract: A device has a latching mechanism including a catch element having at least two catches, and a pawl configured to engage in a catch interstice between two catches. The catch element is movable in relation to the pawl in a freewheeling direction, and a movement of the catch element in relation to the pawl in a blocking direction may be blocked by means of the pawl. The device further includes a deflectable actuator configured to move the catch element and the pawl relative to each other on a catch-by-catch basis in the freewheeling direction by means of deflection. According to the invention, the device also includes an electric component configured to change its electric property as a function of the catch-wise movement of the catch element in relation to the pawl.

  • Publication number: 20190285322
    Abstract: An expansion valve for reducing a pressure of a fluid flowing through the expansion valve along a fluid flow path has: at least one fluid inlet and at least one fluid outlet, a first valve element with at least one first channel structure, a second valve element with at least one second channel structure and a third channel structure, wherein the first and second valve elements are movable relative to each other, wherein, in a first position of the valve elements, the first and second channel structures are aligned with each other and form a first fluid flow path having a first flow resistance between the fluid inlet and the fluid outlet, and wherein in a second position of the valve elements, the first and third channel structures are aligned with each other and form a second fluid flow path having a second flow resistance.

  • Patent number: 8715269
    Abstract: Embodiments of the invention disclose a system for controlled oral drug delivery. The system comprising a removable device comprising a drug to be delivered, wherein the drug is delivered based on osmotic pressure generated in the removable device. Further, the system comprises a receptacle to hold the removable device in an oral cavity, and a base station configured to dock the removable device for determining information about one or more characteristics of the removable device.
