Abstract: The invention relates to an antenna system that includes transmitter component (1, 2, 3, 4), a reception component (4, 3, 10, 11, 12), and an antenna (5) connected to the transmitter and reception components. According to the invention, the antenna (5) is arranged to connect to different connection points (6, 7, 8) of the transmitter (1, 2, 3, 4) or the reception component (4, 3, 10, 11, 12). The invention is also related to a method in connection with the antenna.

Abstract: A board-to-board connector and an arrangement with two circuit boards. A body of the connector is provided with one or more electrically conductive contacts. Such a contact includes a soldering surface for the contact to be attached to a conductive pattern of a first circuit board. The contact further includes a contact surface to be arranged in contact with the conductive pattern of a second circuit board. The second circuit board is arranged at a distance from the first circuit board and substantially parallel therewith. The contact still further includes a spring part arranged between the soldering surface and the contact surface. The contact surface is in immediate contact with a part of the conductive pattern on the surface of the second circuit board and the spring part allows resilience between the soldering surface and the contact surface in a perpendicular direction with respect to a plane of the soldering surface.

Abstract: An electronic device includes a rechargeable power source and a recharging connector arrangement arranged at least partly on an outer surface of the device and configured to connect the power source to a charging apparatus thereof. The recharging connector arrangement is configured to operate as a user interface of the device to control functions of the device.

Abstract: An insert (2) is arranged in an injection mould (1) and plastic is cast onto the insert (2). The insert (2) includes at least one electronic component and connector (4) for testing the component. The injection mould (1) is provided with a counter connector (5) which is arranged to connect to the connector (4). The condition of the insert (2) is tested by a testing device connected to the counter connector (5) during the injection moulding process.

Abstract: The invention relates to clock recovery in optical communication systems. Optical clock frequencies are recovered from a plurality of optical channels by using a single optical resonator. The optical resonator is matched with the carrier frequencies and the sideband frequencies of the data signals sent at different channels. The separation range of the optical resonator is selected such that the clock frequency of at least one data signal is substantially equal to the separation range of the optical resonator multiplied by an integer greater than or equal to two. The method according to the invention allows the use of different clock frequencies at different optical channels. Furthermore, the method provides considerable freedom to select the spectral positions of the optical channels.

Abstract: A connector and a contact wafer. The connector (1) comprises contacts one on top of another and in parallel and the wafer body (8) comprises at least one channel (9) which is arranged between contacts (4) arranged in parallel and extends to the lower surface of the wafer body (8).

Abstract: A connector and a contact wafer. The connector (1) comprises at least two wafers (7) and the contact arms (6) of at least two contacts (4) arranged in different wafers (7) is arranged in the same connector contact space (3). The connector wafer (7) is designed so as to allow simultaneous arrangement of the contact arm (6) of a contact (4) arranged in at least one other wafer (7) in the same connector (1) contact space (3).
