Abstract: Sealing arrangement including a sealing element arranged to seal a gap between a proximal member and a distal member, the sealing element including a sealing material configured to withstand a temperature of at least 100° C.; and a heating element arranged to heat the sealing material to at least 70° C. An industrial robot including at least one sealing arrangement and a method for sterilizing a sealing element are also provided.

Abstract: A permanent short-circuit device includes an enclosure with a first and second fixed electrically conducting body, each connected to a respective conductor leaving the enclosure, the first and second bodies body each having a first and a second surface on opposite sides of the respective body, where the first surface of the first body faces the first surface of the second body and is separated therefrom by a gap with width d and the second surface of the first body is provided with explosives connected to a detonator for deforming the first body towards the first surface of the second body such that the first surface of the first body crosses the gap and galvanically connects to the first surface of the second body.

Abstract: A mechanical switch in the form of a bypass switch assembly is arranged between two electrical conductors (busbars) and stays open during normal operation. When a cell fault happens, the fault and bypass information is transmitted to an actuator (acting as a trigger circuit) which activates inter alia a gas generator producing huge volume of gas in a very short time. The gas pressure pushes a movable member to bridge the two electrical conductors with ultrafast speed.

Abstract: A sealing system including a rotary sealing surface on a rotary shaft and a rotary shaft lip seal, of which the rotary sealing surface has a surface coating layer of a solid lubricant substance. The invention further includes an industrial robot having several axes of rotation, including a manipulator with drive units for rotating robot parts according to the axes of rotation of the robot, and at least one of the drive units having a rotary shaft provided with such a sealing system. In addition, the invention includes a method for providing a rotary sealing surface on a rotary shaft, including coating the intended sealing surface of the rotary shaft with a surface coating layer of a solid lubricant substance.

Abstract: An electric contact element for an arcing contact including a contact body arranged to be applied against a contact element. The contact body includes a Mn+1AXn-material, wherein M is at least one transition metal, A is at least one element selected from group 13-17 in the periodic table, X is C and/or N, and n is 1,2,3 or higher. A method of making a contact element including a contact body including a Mn+1AXn-material. Use of an electric contact element including a contact body including a Mn+1AXn-material in an arcing contact.

Abstract: A varistor including a varistor body with two parallel end faces made of a material that contains one or more metal oxides, and at least one electrode made of an electrically conductive electrode material arranged on any of the end faces of the varistor body. The electrode includes a layer of electrode material coated on the end face by means of an ion- or atom-transferring method, whereby the layer has a thickness within the interval of from 5 micrometers to 30 micrometers.

Abstract: An arrangement and method for imaging and/or measuring tissue qualities, such as tissue thickness, tissue surface roughness and degree of tissue fiber linearization. The arrangement includes at least one light generating element, at least one light detecting element, a probe with an extension, and possibly a control apparatus including a signal processor for processing the detected signals and/or images. The extension is designed to convey light from the light generating element to the tissue for visualization and/or measurement. The extension is also designed to convey light back-scattered from the tissue to the light detecting element. The detecting element is designed to measure the intensity and/or spatial distribution of light back-scattered from the tissue.

Abstract: Device for measuring physical properties of the tympanic membrane (TM), comprising an elongated probe (12) with a distal end (15) for inspection of the ear, wherein a plurality of optical fibres is arranged in said elongated probe. The plurality of fibres includes either a first set of fibres (21) for conveying light from a light source to said distal end of said probe and a second set of fibres (22) for conveying light reflected from the tympanic membrane in front of said distal end to a first detector means (23) or a set of fibres both for conveying light from a light source to said distal end of said probe and for conveying light reflected from the tympanic membrane in front of said distal end to a first detector means (23). Said first detector means (23) is designed for measuring the intensity of light reflected from the tympanic membrane.
