Abstract: An electrical property sensor is presented that includes a printed circuit board with a first face separated from a second face by a thickness, the first face having a length and a width. The sensor also includes an aperture extending from a first face of the printed circuit board to a second face of the printed circuit board. The aperture includes a receiving electrode and a transmitting electrode. When a fluid flows through the aperture and a voltage is provided at the transmitting electrode, a cunent flow is measured at the receiving electrode.

Abstract: A method is described for repairing the surface of rotor blades or aircraft wings, comprising (a) a composite substrate; and (b) a protection layer having at least one area of at least partial damage, the method comprising (i) optionally, removing at least part of the damaged part of the protection tape; (ii) optionally, reconstructing the surface of damaged composite substrate; (iii) optionally, applying primer solution to the surface of the composite substrate; (iv) optionally, applying a polymer solution, preferably in at least one organic solvent; (v) applying a repair patch of a polymer onto at least a part of the composite surface; (vi) applying heat so that the repair patch of a polymer tape melts and covers the damaged area, thereby forming a protection layer or applying a repair solution, preferably in at least one organic solvent, so that the repair patch of a polymer tape at least partially dissolves and covers the damaged area.

Abstract: Radar radiation redirecting tapes (1, 2) include a first plurality of individual radar-reflecting directional antennae (5, 11). Each directional antenna comprises at least three elongate, unevenly spaced antenna conductors (10, 20, 30), arranged with their long extensions parallel to each other in the plane of the tape, such that the directional antenna is operable to reflect incoming radar radiation predominantly in a direction (80) which is orthogonal to the long extension of the antenna conductors and parallel to the plane of the tape.

Abstract: The invention relates to a voltage sensing device (1) for a high and/or medium voltage power carrying conductor (2), the voltage sensing device comprising: a radially outer electrode (3) operable as a first sensing electrode of a sensing capacitor for sensing the voltage of the power carrying conductor; a radially inner electrode (2, 6) operable as a second sensing electrode of the sensing capacitor; a dielectric material (5) arranged between the inner and the outer electrode (3, 2, 6), wherein the coefficient of thermal expansion of the material of at least one electrode (3, 2, 6) is selected such that it compensates the temperature dependent parameters of the dielectric material (5) and/or the other electrode (3, 2, 6), that influences the capacity of the voltage sensing capacitor.
