摘要:
A power supply power supply (30) comprising a DC voltage supply, a control unit and a plurality of high voltage channels (33a-33d) is suggested. Each high voltage channel (33) includes an inverter (IKTV), a resonance circuit, a transformer (TR), and a rectifier (RECT). The resonance circuit cooperates with the inverter (INV). The inverter (INV) is formed by a first switching unit and a second switching unit whereby a voltage of a first polarity can be applied to the resonance circuit in a first switching state, whereas a voltage of a second polarity can be applied to the resonance circuit in a second switching state. The switching states can be switched by the control unit in such a manner that in a first mode of an operation for high output power, the output power can be adjusted by changing the switching frequency in the range of the resonance frequency. In a second mode of operation for low output power, the output power can be adjusted by changing the duration of the switching state at an essentially constant switching frequency.

Tools for compacting composite parts are disclosed. These tools are used while layers of composite material, such as tows or laminae, are being deposited onto a fabricating surface, such as a mold or other forming tool. The compacting tool is typically divided into a series of narrow segments, each segment able to advance or retreat individually so as to conform to the surface of a composite part being formed. Pressurized fluid, such as air or hydraulic fluid, or non-pressurized internal bladders with incompressible fluid, are used to evenly apply pressure to the segments in order to compact the material with which the tool and the segments are in contact. The compacting tool thus helps eliminate voids and helps the material conform to the desired shape on the forming tool.

A contact element for the intermittent contacting of conductor tracks on a circuit board, in particular, for flexible touchpads, for example for flexible input devices in the automobile industry, is made from a metal foam. The metal foam may be at least partly infiltrated by an elastomeric material which can also be the material of construction of the touchpad. The contact element has a very reliable construction which is particularly suitable for high voltage application. A method for production of the contact element, touchpads/input devices with such contact pads and the use of the contact pads is also provided.

The prior art cannot implement the feature call hold in a FMC network (fixed mobile conversion, i.e. mixed mobile fixed networks). This is due to the fact that the feature call hold as well as the features conference calling and three-party service have different definitions in the two standards ITU-T Q1912.5 and 3GPP TS 24.228 with which incompatible procedures are defined. Compatibility problems arise since all involved units in the FMC networks with different units such as clients and network transition units necessitate an inter-working of all interlinked units. This problem is resolved by providing a mapping functionality that converts the protocol elements of both standards into one another.

The invention relates to a method for signaling call diversion parameters in a SIP network (12), according to which to signal the call diversion a Provisional Response 18× or a Response 3×× according to IETF RFC 3261 is used, which comprises diversion codes. For connections between the SIP network (12) and a further network (3) the invention also provides a [lacuna] for the bi-directional conversion of SIP messages or SIP-T messages to a protocol of the further network (3).
摘要:
A circuit arrangement for limiting the current at make for a transformer wherein, in order to avoid the current peak at make when switching a transformer on, resistors are connected between operating voltage and the primary winding of the transformer. A test winding at the secondary side of the transformer is connected via a rectifier to the supply input of a contactor, so that the switches of the contactor close after the transformer is turned on and the resistors therefore no longer lie between operating voltage of the primary winding. PTC-resistors connected in series with the resistors assure that the resistors are not overloaded by the high-operating current of the transformer if the switches do not switch.
