摘要:
In a method and a signal distribution arrangement for use in private dwellings or offices, communication and multimedia signals are distributed by means of a connection arrangement (27) which is connected to a plurality of terminals (1-8) in the rooms (25, 26) of the dwelling or the office. The individual terminals are preferably identical and may be connected between the terminals and the consuming apparatus via a cable with a plug at each end which is adapted to the terminals and a consuming apparatus, respectively. The signal distribution arrangement includes a plurality of signal processing circuits (31-33) which have wire connections (patch cables) that may be connected to a patch panel (1-23), each of which is either connected to the terminals or is prepared to be connected to the new terminals. Hereby, the power distribution may be adapted to the needs of the individual user in a simple manner at any given occasion without requiring expensive installation changes, as the various signal types may be converted from one signal type to another signal type either in the signal processing circuit or after the terminals.

A lamp comprising a lamp housing (2) and a lamp glass (3) as well as internal, electric components has an insulating bowl (9) for receiving the internal electric components so that these are arranged water- and moisturetight. In a preferred embodiment, the bowl (9) has an open side which faces toward the lamp glass (3) so that the water- and moisturetight space is formed by the bowl (9), the lamp glass (3) and a sealing ring (18).

A building system for providing walls with concealed ducts comprises studs (15) for supporting wall plates (18) and comprises duct members (17) for constructing a duct which is concealed in the finished wall. When the duct member (17) and/or the stud (15) is reduced in depth (transversely to the finished wall), ducts and studs may pass each other, without the wall losing its strength, and without the field of use of the duct being reduced noticeably.

A method of reducing signal coupling in a connector for the transfer of balanced electrical high frequency signals, said connector comprising contact springs (5) and terminals (4) as well as a plurality of pairs of conductors arranged in an insulation member (9) to connect the contact springs (5) and the terminals (4), each said pair of conductors being capable of transferring one of the balanced signals. The pairs of conductors in the insulation member are arranged in two mutually spaced layers in such a manner that each of the two conductors (6) belonging to a pair is arranged in a layer of its own, and that the insulation member (9) is made of at least two dielectrics with different permittivity. The invention also relates to a connector and a connecting element for the transfer of balanced electrical high frequency signals as well as a cable terminated by a connector according to the invention at one or both ends.
摘要:
A controllable microswitch comprises a closed cavity having a plurality of contact electrodes, a movable switch body capable of making and breaking an electrical connection between the contact electrodes, and a plurality of control electrodes capable of generating an electrical field to control the position of the switch body. The switch body is formed by a diaphragm which is provided with a conducting surface and which divides the cavity into two subcavities. A method of making such a microswitch is moreover disclosed. The microswitch may be used for power regulation of systems connected to an electrical voltage source and for remote-controlled connection and disconnection of an electrical apparatus.
