  • Patent number: 11703127
    Abstract: A seal assembly includes: a seal element; a part to be sealed; and a measuring arrangement for monitoring an aging of the seal element. The seal element is held on the part so as to provide a contact stress between the seal element and the part. The seal element has a contact face with which the seal element bears against the part. At least one measuring component of the measuring arrangement is integrated in each case into the seal element and into the part. The contact face of the seal element has a surface geometry with depressions.

  • Patent number: 9480321
    Abstract: The invention relates to a motor-driven epilation head for an epilation device for plucking hairs of the human skin. Specifically, the invention relates to an epilation head having a rotation cylinder that can be rotated about a rotation axis and includes a plurality of plucking units for capturing and plucking the hairs. Each plucking unit comprises a first clamping element, a second clamping element and a third clamping element. The first clamping element together with the second clamping element forms a first closeable plucking gap and the second clamping element together with the third clamping element forms a second closeable plucking gap. The first and the second clamping elements are movably mounted and can be jointly actuated by means of an actuation element in order to close the first and the second plucking gap. The first and the second clamping elements move in the same direction.
