Abstract: An extreme ultraviolet radiation (EUV) source, including: a vessel having an inner vessel wall and an intermediate focus (IF) region; an EUV collector disposed inside the vessel, the EUV collector including a reflective surface configured to reflect EUV radiation toward the intermediate focus region, the reflective surface configured to directionally face the IF region of the vessel; a showerhead disposed along at least a portion of the inner vessel wall, the showerhead including a plurality of nozzles configured to introduce gas into the vessel; and one or more exhausts configured to remove gas introduced into the vessel, the one or more exhausts being oriented along at least a portion of the inner vessel wall so that the gas is caused to flow away from the EUV collector.

Abstract: The present invention relates to a method for avoiding a collision between a vehicle and another traffic participant. According to the inventive method, a cell phone carried by the traffic participant sends a signal including a position of the traffic participant. A processing unit processes the signal including the position of the traffic participant for a position or evaluation history. The processing unit determines an estimation of a future position of the traffic participant on the basis of the position or evaluation history. The processing unit evaluates a likelihood of a collision between the vehicle and the traffic participant on the basis of the estimated future position of the traffic participant and an estimation of a future position of the vehicle. An acceleration of the traffic participant is sensed by an acceleration sensor of the cell phone.

Abstract: The present invention relates to a method for controlling sleep mode in a terminal comprising at least two network interfaces. According to the present invention, the method comprises the steps of: Switching off one of the two interfaces; Activating the switched off interface for a predefined time window upon reception of a predefined signaling message on the other interface.

Abstract: The present invention presents a flexible method for source-based message routing in a network node, particularly also suitable for flexible load distribution of the traffic via a number of link sets terminating directly at an adjacent first network element. The method uses data structures which are often already available in existing systems or are simple to set up, of providing a number of link sets between two signaling points. A two-stage routing process is initiated based on the setting up of a message node, which supports a number of logical networks or signaling point codes. In the first stage a logical network is selected, in which the message is to be routed further. In the second stage the message is routed in the selected network.

Abstract: An apparatus, system and method for converting point codes in a signal transfer point, STP, in a telecommunications signaling system. The STP includes a point code conversion function (500) which converts point codes designating the origination and destination signaling points for a signaling message. The conversion function can be incorporated between the signaling link layer (200) and the network layer (300) of the message transfer part, MTP, functionality of the STP.

Abstract: There may be applications where for IN-calls, one SCP begins processing a transaction for supporting a service but another SCP continues processing said transaction. The invention shows how such a continuation of processing can be carried out in cases where this can be solved in terms of protocol.

Abstract: The invention relates to a method for transmitting signalings in different networks which is characterized in that at least two signaling gateways are interlinked using a point-to-point protocol for symmetric and quasi-associated signaling.

Abstract: According to the invention, a connection is routed both via a slow, but broad-band path and via a high-speed, but narrow-band path. The slow path is used for the primary transport of the message. The second path is used for the retransmission requests and/or the retransmissions. There is thus little traffic on this path. The entire connection however has the delay characteristics of the slow path for a faultless transmission.

Abstract: Both user data and monitoring information are transmitted in communication protocols. While (message) packets with user data are successively numbered in many protocols, thus ensuring that the user data are transmitted completely and with a protected sequence to the receiver, messages which contain only monitoring information are not normally successively numbered. This situation can lead to monitoring messages being overtaken, and thus to the rejection of current monitoring information. The invention describes how the rejection of current monitoring information can be avoided.

Abstract: A process for dynamic channel allocation in mobile radio networks, wherein priorities which are increased or decreased in dependence on interference occurring in the channel concerned are established for the individual channels. When the propagation conditions are satisfactory, channels with low priority can be allocated. The mean of values dependent on the extent of interference can be formed in order to increase and decrease the priority. In addition, various priority lists can be established for various interference or load situations, or both.

Abstract: The ATM communications network (NW) has a plurality of network nodes (NK1, NK2, NK3) connected with one another via at least one transmission medium, which respectively represent at least one signaling point, corresponding to a defined outband signaling. At least one virtual channel is respectively provided on the respective transmission medium between adjacent signaling points for the transmission of signaling information defined according to a network protocol and of network management information. At least one further virtual channel, allocated exclusively to the network management information, is respectively reserved on the respective transmission medium for the transmission of the network management information between adjacent signaling points.

Abstract: A cleaning cone with a covering for cleaning the internal taper of the work spindle of a machine tool is rotatably mounted on a mandrel on a supporting body. The cone and the mandrel are relatively movable. The apparatus is detachably secured in the operating position.

Abstract: A self-sinking, axial passage foundation pile and method are provided. The pile is preformed with an axial bore which is capable of accommodating a rotatable shaft. At one end of the pile a drill bit is affixed to the shaft and at the other end a driving means is attached to the shaft in order to rotate the drill bit. In this configuration the rotational drilling torques are transmitted by the shaft without importing torque to the pile. Accordingly, the pile need not be specially reinforced to accommodate the bore hole drilling torques. Furthermore, the invention encompasses the novel method for installing the unique pile disclosed.
