  • Publication number: 20240091420
    Abstract: The present invention relates to a method and an apparatus for treating breast milk, in which a breast pump is applied to the female breast and the breast pump is operated to express and transfer breast milk to a container. The container is sealed, wherein the container is or will be provided with a container identifier that identifies the container. A container identifier identifying the container is generated and assigned to the container. In order to avoid interference with breast milk, it is made available in the container for feeding.

  • Patent number: 9518858
    Abstract: The present invention relates to a guided wave radar level gauge system comprising a transceiver for generating an electromagnetic transmit signal within a predetermined frequency range having a center frequency, a flexible single conductor probe having a first end connected to the transceiver and extending towards and into the product to a second end of the flexible single conductor probe; and a probe aligning member attached to the second end of the flexible single conductor probe for keeping the flexible single conductor probe substantially vertically extending from the first end to the second end. The probe aligning member exhibits a horizontal extension that increases with increasing distance from the first end of the flexible single conductor probe along a vertical distance greater than one half of a wavelength of the transmit signal at the center frequency. Hereby, determination of filling levels close to the bottom of the tank is improved.

  • Patent number: 9408755
    Abstract: The invention relates to a wound drainage covering for covering, by means of low pressure, a wound that is to be treated. The covering comprises at least two layers that are superimposed. A first layer that is applied on the side of the wound is made of a functional textile material and second layer that is arranged thereon is dimensionally stable and permeable to liquid. The wound drainage covering has a simple design and due to the functional first layer, is effective and ensures, due to the dimensionally stable second layer, an optimal removal of wound secretion.

  • Patent number: 9322699
    Abstract: The present invention relates to a radar level gauge comprising a reference reflector arranged at a known reference reflector level in a tank. The radar level gauge is controllable between a filling level measuring state and a proof test state. In the proof test state, the radar level gauge is configured to determine a first verification level based on a reference reflector echo resulting from reflection of an electromagnetic transmit signal at the reference reflector; determine a second verification level based on a surface echo resulting from reflection of an electromagnetic transmit signal at the surface of the product; and provide the first verification level and the second verification level to allow determination of a proof test result based on at least the first verification level, the known reference reflector level and the second verification level.
