    • A secure payment system for authorised point of sale transactions enables a user to pay electronically for goods using a handheld device such as a mobile phone (115). No confidential information need be held on the handheld device (115), all financial data being held within the payment system. A short-range wireless connection is provided to the handheld device (115) and the user has only to enter a PIN to initiate a transaction. The system includes a client device (100) and a server device (110). The server device (110) maintains user profiles which enables customisation, for example of transaction receipts and payment methods. Transaction receipts can be transmitted to a preselected location, for example by email or SMS, which provides an additional security check for the user.

    • A fluid flow meter comprises a pair of transducers spaced apart in the direction of fluid flow. A transmitter causes acoustic signals to be transmitted in both directions through the fluid by the transducers. A processor determines information relating to the fluid flow by monitoring the time of flight of acoustic signals received by the transducers. Part of the space between the transducers defines a flow path consisting of a flow structure having a plurality of parallel fluid flow passages which extend axially in the direction of flow, wherein the cross-sectional diameters of the passages are chosen such that substantially plane acoustic waves only are transmitted through the passages by the fluid, and wherein under working conditions the fluid flows through each passage such that the ratio of the volume flow rate through the passage to the total volume flow rate remains substantially constant with respect to the total volume flow rate.

    • A system and method for self-organizing, reliable, multiple path data flow transmission of messages data on a network uses queues to transmit messages between end-user modules (EUMs) on nodes on the network. The EUMs include the end user applications with which queues are associated. A network communications manager (NCM) resident on every node manages all transmission of messages between nodes. The NCM on a given node only has knowledge of nodes that are neighbor nodes to that given node, but has knowledge of all queues associated with all EUMs. Messages are divided into EUM messages, which are placed in queues by the NCM on each node, and system messages, which are not placed in queues but are used by the NCM to determine when and where, i.e. to which neighbor node, messages may be sent. The NCM on each node chooses a neighbor node as a target node for sending EUM messages for each queue, based on the best node latency and at capacity status of each neighbor node. These target nodes are used to provide potential routes to queues and multiple path data flow for queues that carry EUM data messages for user applications. These target nodes are constantly updated to provide the best paths on an adaptive basis and to ensure that all paths are valid, improving network reliability. When choosing when to send data to a target node, each node uses tokens for flow control to ensure that target nodes do not become overloaded. The node also compares node latencies for multiple target nodes to ensure that the lowest node latency target node is chosen. By using neighbor nodes as target nodes, node latency, and at capacity information for determining when and where to send data, there is no need to maintain any global knowledge of all paths in the network. Further, the constant updating of target nodes ensures that the network maintains optimal and valid paths for messages, thus ensuring efficiency and reliability. Finally, the constant updating of target nodes ensures that reliability and efficiency are provided on an adaptive, self-organizing basis.

    • This invention relates to a phase shifting device, which generally comprises of rigid chassis, in the form of an aluminum plate, which can form a ground plane for feed lines (12) printed on a printed circuit board (16), which is mounted on the chassis, a rigid RF transparent block, which is fixed to an actuator arm and mounting bolts for slidably mounting block and actuator on the chassis. A flexi circuit, or the equivalent, (18) is attached to the block and is printed with generally c-shaped conductive strips (23), which form connections at open parts of the feed lines, in such a manner that movement of the block will cause changes in the effective lengths of the feed lines (12) and hence the relative phases of antennas fed by those feed lines.
