An alert system for an electronic housing, including: a gas property sensor, wherein a processor is configured to receive gas property data from the gas property sensor, and configured to determine a property of a battery included in the electronic housing; a degassing unit for attaching to the electronic housing and configured to enable passage of gases and to prevent passage of liquids and solids, the gas property sensor being attached to the degassing unit at an inner side. A degassing unit comprising a base comprising an attachment means for fluid-tightly attaching to a venting opening of the electronic housing and an opening covered by a semipermeable membrane thereby forming a gas passage; a sensor module including a gas property sensor, the sensor module attachable to the base on an inner side of the base, the sensor module extending away from the semipermeable membrane towards a direction substantially perpendicular to the semipermeable membrane.

Alert system, degassing unit for an electronic housing, and electronic housing comprising degassing unit

An active material container for a functional housing has an air-permeable casing with an interior and an active material arranged inside the interior. One or more rim-side guide elements are arranged at the air-permeable casing and are provided to linearly slidably guide the active material container in an insertion direction in corresponding guide elements of a receptacle of the functional housing. The functional housing is preferably a battery housing.

Active material container, battery housing, and method for mounting the active material container in the battery housing

A humidifier has a stack unit having a plurality of water-vapor-permeable membranes which are arranged parallel one above the other and spaced apart from one another. The membranes are enclosed at the edges at least in sections by an enclosing part, wherein the enclosing parts of membranes lying one above the other are directly connected to one another in a flow-tight manner.

Humidifier, in particular for a fuel cell

A humidifier has a stack unit having a plurality of water-vapor-permeable membranes which are arranged parallel one above the other and spaced apart from one another. Two adjacent membranes are connected to one another via fixing elements, wherein a first fixing element acts on the top membrane from above and a second fixing element acts on the bottom membrane from below.

Humidifier, for example for a fuel cell

A humidifier having at least one water-permeable fabric layer, on the opposite sides of which a gas stream with higher and with lower moisture content is guided along. On the side of the gas stream with higher moisture content, a hydrophilic additional layer is positioned upstream of the fabric layer.

Disclosed are an air filter element, a filter housing, and an air filter in which the air filter elements have a high filtering capacity and a long service life by increasing the filter surface of an air filter element taking into account structural requirements for the air filter housing.

Air filter element and air filter

A method and system of determining fiber diameter distribution of a fibrous media is disclosed. The method includes providing at least one digital image representative of the fibrous media, pre-processing the images, binarizing the images, generating virtual lines on the image, solving for fiber fringe points on each of generated line, solving for fiber center points as a mean of the fringe points, generating and growing measurement circles about the fiber center points, repositioning circles and center points to avoid fiber intersections, resizing the repositioned measurement circles to intersect the opposing fringes, and calculating fiber diameters and fiber spacing.

Method and system of determining the fiber diameter distribution of a fibrous media

An apparatus for filtering a liquid, with a housing, a liquid inlet arranged in the housing, a liquid outlet arranged in the housing, a filter for removing particles from a liquid stream arranged between the liquid inlet and the liquid outlet, and at least one additive for functionally altering the liquid properties arranged in the apparatus, in which the additive is arranged in the interior volume of the apparatus and is shaped in a colloidally disperse, dimensionally stable, elastic form corresponding to at least one geometric space defined by an interior structure of the apparatus or of the filter for removing the particles.

Additive dispensing filter apparatus

An apparatus for storing water separated from fuels by a fuel filter is provided. The apparatus includes an absorber connected to a water accumulator of the fuel filter. The stored water may then be released again through heating or pressure using commercially available components and supplied to a further use.
