  • Packet scheduler and method therefor
    Patent number: 6775256
    Abstract: This invention relates to a packet scheduler and method therefor and in particular a scheduler for a Code Division Multiple Access cellular mobile communication system. In packet base systems it is important to schedule transmissions of packets carefully in order to maximize the capacity of the system. The scheduler has a selection unit (233) for selecting a candidate set of packets. The candidate set is fed to a processor (235) for calculating transmit powers required by remote terminals to transmit the packets based on the candidate set. The calculated transmit powers are fed to a controller (237) for modifying the candidate set in response to the calculated transmit powers and the modified set is fed to a scheduler unit (239) for scheduling the packets of the candidate set for transmission. The scheduler is in particular appropriate for third generation mobile communication systems.

  • Benzoheterocycles and their uses as MEK inhibitors
    Patent number: 6469004
    Abstract: The invention provides compounds having formula (I), wherein W is OH, or derivatives of the carboxylic acid, and Q is a heterocyclo-condensed ortho-phenylene residue. These compounds are useful as MEK inhibitors, particularly in the treatment of proliferative diseases such as cancer.

  • Software development process
    Publication number: 20020104068
    Abstract: A flexible component-based software system is developed by generating a UML model (3) in a specification phase (4). Components are generated in an implementation phase (4). The UML model (3) is transformed to a meta model. A runtime architecture service (RAS, 10) dynamically assembles a system in runtime according to the meta model. A modelling tool (15) modifies the meta model via an API (34) and a meta modeller (31). This allows dynamic re-configuration of the system.
