Abstract: Disclosed is a cleaning system (1) for cleaning the plate channels (2) in a plate heat exchanger (3) during normal use of the heat exchanger (3), wherein the heat exchanger (3) comprises an inflow channel (4) through which a fluid enters the heat exchanger (3) and an outflow channel (5) through which the fluid exits the heat exchanger (3). A stack (6) of heat exchanger plates (7) is arranged between the inflow channel (4) and the outflow channel (5) so that the heat exchanger plates (7) form plate channels (2) between the inflow channel (4) and the outflow channel (5) through which the fluid may pass.

Abstract: A method and system are presented in which communication redundancy is provided. Multicast packets having the same audio and/or control data are simultaneously transmitted between an RF site and different switches through different communication links. The packets from the RF site have different origination addresses and a unique ID, which permits duplicate packets having different origination addresses but the same unique ID and data to be eliminated and only one set of packets to be transmitted over the air to a receiving end device for which the packets are intended. A switch communication link between the switches permits the primary switch to establish operating characteristics for the alternate switch.

Abstract: A wireless communications network (100) comprising a plurality of sites, each of which is served by a base transceiver station (102, 106, 110, 114, 118, 122, 126, 130). The base transceiver stations (102, 106, 110, 114, 118, 122, 126, 130) are connected with other elements of infrastructure (134-142) and at least one of said base transceiver stations (102) comprises means (104) for determining its geographical location. Said base transceiver station (102) is adapted to be moved from a first geographical location to a second geographical location. A first database (146) is configured to store location data of said base transceiver stations (102, 106, 110, 114, 118, 122, 126, 130). The network (100) further comprises a controller (144) configured to receive location data from the at least one base transceiver station (102) and from the first database (146) and to determine adjacency of sites.

Abstract: A method of controlling location information of subscribers (210, 212, 222) in a wireless, ad-hoc communications network (200). The network (200) comprises a plurality of nodes (204, 216, 226), wherein at least portion of said nodes are provided with Home Location Registers (HLRs) (206, 218, 228) and each of said nodes (204, 216, 226) has a Visitor Location Register (VLR) (208, 220, 230). When an operation of a first node (216) is to be reconfigured at least a part of records from a first HLR (218) assigned to said first node (216) are transferred to at least one of the other nodes (226) of the network (200).

Abstract: A wireless, ad-hoc or private communications network comprising nodes, forming with other elements of the network a switching and management infrastructure (SwMI), and subscribers, wherein each of said nodes has a Visitor Location Register (VLR), and at least a part of said nodes are provided with Home Location Registers (HLRs) and at least a part of said nodes with said HLRs are provided with gateways, wherein in said network every node with an HLR is assigned to a node having a gateway and said SwMI directs calls to and from a subscriber of said network to an external network.

Abstract: A wireless, ad-hoc or private communications network (100) comprising nodes (102, 112, 120, 130, 140), forming with other elements of the network a switching and management infrastructure /SwMI/, and subscribers, wherein each of said nodes (102, 112, 120, 130, 140) has a Visitor Location Register /VLR/ (108, 118, 126, 136, 142), and at least a part of said nodes (102, 112, 120, 130) are provided with Home Location Registers /HLRs/ (106, 116, 124, 134) and at least a part of said nodes (102, 120) with said HLRs (106, 124) are provided with gateways (110, 128), wherein in said network (100) every node (102, 112, 120, 130) with an HLR (106, 116, 124, 134) is assigned to a node (102, 120) having a gateway (110, 128) and said SwMI directs calls to and from a subscriber of said network (100) to an external network via said assigned node with a gateway.

Abstract: A method and equipment are described for performing measurements while drilling for oil or gas, in particular VSP-measurements employing a seismic source together with sensors such as hydrophones and/or geophones connected to a memory- and calculation device for storing and processing the seismic signals. The seismic source (2) is placed at or in the vicinity of the surface of the earth whereby signals generated by the source are detected by the hydrophones (3,5) or the geophones located in the vicinity of the source (2) at the surface and in the drill string (4). The geophones or the hydrophones (5) in the drill string transmit the detected signals to a memory- and calculation unit (6) in the drill string that processes and transmits the signals completely or partly to a central data processing unit (10) on the rig (7).
