  • Publication number: 20230235583
    Abstract: A mortar applicator includes: a duct; a piston movably mounted within the duct, dividing the duct into first and second variable volume chambers; a pump fluidly connected to the first variable volume chamber; a nozzle operatively connected to a first end of the duct to discharge mortar contained in the first variable volume chamber; and a motor operatively connected to the piston. A rack and pinion assembly operatively connects the motor to the piston and includes a rack configured to drive the piston and a pinion connected to the motor. In a discharge mode, the motor drives the rack and pinion assembly, moving the piston to force mortar through the nozzle opening to discharge mortar from the mortar applicator. In a refill mode, the pump fills the first variable volume chamber with mortar, forcing the piston to retract. The rack moves with the piston in the discharge and refill modes.

  • Publication number: 20110246581
    Abstract: A method and an Event Tracking System (ETS) are provided for group communications. The method allows subscribing with an Event Organizing System (EOS) for updates to a group event instance comprising a group of users and an event related to the group, e.g. a hockey match. The method further allows receiving from users subscriptions to the updates of the group event instance. Responsive to subscribing with the EOS for the updates to the group event instance, the ETS receives from the EOS an update notification related to the group event instance notifying of a group event update (e.g. an update of the group membership and/or of the event), and responsive to the user subscriptions with the ETS, the later sends out an update notification message to each one of the users notifying of the group event update. In one embodiment, the update notifications sent out to users are personalised, e.g. based on the user's location or advertisement preferences.

  • Publication number: 20080113670
    Abstract: A method and a radio network manager (RNM) for managing a list of target cells associated to a source cell in a telecommunications network. The RNM comprises an input/output (I/O) unit for receiving a file containing at least one record associated to the source cell from a base station controller (BSC). The RNM also comprises a processor for determining for each record whether a target cell is missing from the list of target cells identifying the target cell as missing from the list of target cells, if the target cell is missing from the list of target cells. The RNM determines for each record whether a target cell is excessive from the list of target cells and removes the target cell, if the target cell is excessive from the list of target cells. Afterwards, the RNM sends an updated list to the BSC.

  • Patent number: 6982299
    Abstract: A low gloss thermoplastic molding composition comprising a grafted acrylate rubber (ASA) and a process for its preparation are disclosed. The composition contains an effective amount of a gloss-reducing agent that is the reaction product of (i) compound having two or more maleic anhydride groups per molecule and (ii) compound having two or more terminal primary amine groups per molecule. The incorporation of the gloss reducing agent in the inventive composition may be by blending the reaction product or, in the alternative, blending the reactants (i) and (ii) in the molten ASA under process conditions designed to bring about the in situ formation of the inventive gloss reducing agent.

  • Publication number: 20050125515
    Abstract: A method and manager node is provided for verifying status information of Managed Objects (MOs) of a management system before propagating an update to a managed network. Subsequent to an attribute change of a given MO in the manager, the manager detects other MOs related to the updated MO, such as neighbour radio cells of a given radio cell. The manager obtains status information relative to each related MO, such as synchronization information, connection information or coupling information. If the status information is adequate for pursuing the update, the manager propagates the update to the managed network. Otherwise, the manager issues a warning to the system administrator, and only propagates the change to the managed network when confirmed by the systems administrator.

  • Publication number: 20050120100
    Abstract: A method and manager node for setting a synchronization status of a Managed Object (MO) based on an outcome of synchronization between the manager and a related Network Element (NE). An attribute of a management system's first MO that represents a first NE of a managed network is changed in the manager. Responsive to the attribute change, and because the first NE is related to a second NE of the managed network, the manager initiates an update of a second NE of the managed network for propagating the change to that second NE, in addition to updating the first NE, and further determines whether or not the update of the second NE has been completed successfully. The manager sets a synchronization attribute of a second MO that represents the second NE in the management system to a value representative of an outcome of the update of the second NE.

  • Patent number: 6807424
    Abstract: Radio environment statistics data useful in determining frequency plan revisions is collected in each one of a plurality of separate recording periods. Following conclusion of each recording period, a frequency plan revision algorithm is executed to process the collected radio environment statistics data and determine a frequency plan revision for implementation. The collected data that is considered by the algorithm includes not only that data which was collected in a current recording period, but also that data collected in previous recording period(s) thereto. More specifically, only the previous recording period data that is considered reliable is processed by the algorithm along with the current recording period data. Reliable data is identified as that data relating to a measurement made on frequency whose radio environment statistics have not been adversely affected by an implementation of a frequency plan revision in the meantime since making the measurement.

  • Patent number: 6311067
    Abstract: Utilizing a sequential local search optimization algorithm, a determination is made of the cell/transceiver retunes needed to implement, given a current frequency plan, a better frequency plan for a certain cellular communications system. Each of the individual cell/transceiver retunes is evaluated to determine if it meets certain save criteria, and if so, is saved as an intermediate frequency plan in a sequence of saved intermediate frequency plans necessary to migrate from the current frequency plan to the determined near-optimal frequency plan. A sequential implementation of these intermediate frequency plan revisions is then made to gradually reach, in a known and controlled manner, the better frequency plan.

  • Patent number: 6212386
    Abstract: Interference and bit error rate measurements are made on the uplink and downlink to determine communications quality. Mobile station mobile assisted hand-off (MAHO) functionality is utilized to make the downlink measurements. Following filtering, the measurements are evaluated to identify potential candidates for reallocation. In one type of evaluation, when measured downlink bit error rate on a selected frequency is lower than a threshold and is worse than measured uplink bit error rate, then a better quality candidate is chosen to replace the selected frequency. In another type of evaluation, when a best available candidate has better interference than a worst quality one of the selected frequencies, that best candidate is chosen to replace the selected frequency.
