Abstract: An electrowetting optical element comprising a first electrode layer and a second electrode layer opposite said first electrode layer, and a containment space formed between said first and said second electrode layer. The first electrode layer comprises an insulating layer, and a hydrophobic surface layer contiguous to said containment space. The electrowetting element further comprises a barrier layer in between said insulating layer and said containment space, for preventing ion migration of ions from said containment space into said insulating layer, for preventing charge accumulation in said insulating layer. The disclosure further relates to a method of manufacturing an electrowetting element.

Abstract: The present invention is directed to a mirror system for a vehicle, said mirror system having a viewing surface for being operable as a mirror, said mirror system comprising a specular reflective surface and means for controlling an amount of light transmitted between said specular reflective surface and said viewing surface, said means for controlling said amount of light transmitted comprising at least one transmission control element and control means for controlling said transmission control element, characterised in that said transmission control element is an electrowetting element. The present invention is further directed to a method of operating said mirror system.

Abstract: The present invention relates to a mirror device, the reflectivity of which may be varied by means of applying a voltage. According to an aspect of the invention, there is provided a mirror device, the reflectivity of which may be varied by means of applying a voltage, comprising a cholesteric filter (33) which is arranged to be gradually switchable between a reflective and a transparent state by varying said voltage, and a display device (32) arranged to be at least partly covered by the cholesteric filter, wherein said display device is visible when the cholesteric filter is set in the transparent state and hidden when the cholesteric filter is set in the reflective state.

Abstract: The electronic device (10) comprises an integrated circuit (30) with a first (18) and a second side (19), on both sides (18, 19) of which first and second conductive areas (31, 32) are present. The electronic device (10) further has a first (64) and a second (65) conductive structure, which (64, 65) are present on a—preferably enveloping—layer (71) of dielectric material. Signal and power to and from the integrated circuit (30) are transferred through capacitors (11, 12) formed by the conductive areas (31, 32) and the conductive structures (64, 65) and an intermediate layer (73, 74) of dielectric material. The integrated circuit (30) may contain a protective layer (33) in the second conductive area (32).

The invention further relates to an appliance provided with a transponder which comprises an integrated circuit, an antenna, and a first capacitor.

Abstract: Disclosed are a lithium battery and methods for the manufacture thereof. Such a lithium battery includes a stack of a negative electrode, a separator, and a positive electrode. In the manufacturing methods, a pattern of holes is produced in the negative electrode as well as in the positive electrode, and a polymeric material is caused to penetrate the holes, whereby the negative electrode, the positive electrode and the separator are stuck and pressed together. Moreover, the negative electrode and the positive electrode are provided with an alignment pattern which can be used for the purpose of aligning the electrodes. The presence of such an alignment pattern facilitates the alignment of the layers with respect to each other.

Abstract: Disclosed are a lithium battery and methods for the manufacture thereof. Such a lithium battery at least comprises a stack of a negative electrode (12), a separator (7), and a positive electrode (11). In the manufacturing methods, a pattern of holes is produced in the negative electrode (12) as well as in the positive electrode (11), and a polymeric material is caused to penetrate the holes, whereby the negative electrode, the positive electrode and the separator are sticked and pressed together. Moreover, the negative electrode and the positive electrode are provided with a pattern (4, 5, 6) which can be used for the purpose of aligning the electrodes. The presence of such a pattern facilitates the alignment of the layers with respect to each other.
