  • Patent number: 9608741
    Abstract: A system and method of an electronic apparatus for use in a communication system includes a switching module arranged to combine a plurality of input signals received by a plurality of input ports in connection with the switching module to define a combined input signal having a plurality of frequency components; and a loading module arranged to receive the combined input signal from the switching module and to individually separate each of the plurality of frequency components of the combined input signal by processing the combined input signal with a plurality of resonating networks, each arranged to resonate at a resonance frequency associated with each of the plurality of frequency components of the combined input signals.
    Type: Grant

  • Patent number: 6649647
    Abstract: This invention relates to compounds containing a trioxane moiety, especially certain artemisinin derivatives, which have cytotoxic and antitumour activity and their use in the treatment of cancer. Some of these compounds comprise a ligand which is capable of binding to a nucleic acid and a group containing a trioxane moiety which is capable of acting as source of free radicals which are capable of chemically interacting with a nucleic acid. Processes for the preparation of such compounds and pharmaceutical compositions containing such compounds are also provided.
