Abstract: A negative pressure wound treatment assembly comprising: a covering layer, a vacuum system comprising: a chamber having a tightly closed space with a reduced pressure, said chamber comprising an end closed by a perforable cap, a connecting device adapted to be attached to the covering layer and to the chamber to form a communication passage between the covering layer and the space of the chamber, the connecting device having at least one needle portion adapted to perforate the cap of the chamber, the connecting device comprising at least one valve member, wherein the valve member comprises a cover mounted on the needle portion, said cover covering a tipped end of the needle portion in a closing position and being adapted to be resiliently deformed to an opening position.

Abstract: Disclosed herein is a method for producing an LED array grid including the steps of (i) arranging N electrically conducting parallel wires, where N is an integer >1, thus creating an array of wires having a width D perpendicular to a direction of the wires, (ii) arranging LED components to the array of wires such that each LED component is electrically coupled to at least two adjacent wires, (iii) stretching the array of wires such that the width D increases, and arranging the stretched LED array grid onto a plate or between two plates

Abstract: The invention relates to an optoelectronic input device (10) in which the input is formed by detected movements of an object (M), the device comprising an optical module (11) comprising at least one laser (1,1?) with a cavity for the generation of a measuring radiation beam (S), optical means (2) for the guidance of the radiation beam (S) to a plane (V) close to the object (M) and conversion means (C) for the conversion of measuring beam radiation reflected and modulated by the object into an electrical signal, wherein the conversion means (C) are formed by a combination of the cavity of the laser (1) and measuring means (3) for measuring a change in the cavity during operation, which radiation is caused by reflected radiation entering the cavity.
