    Abstract: Sterilisation apparatus arranged controllably to generate and emit hydroxyl radicals. The apparatus includes an applicator which receives RF or microwave energy, gas and water mist in a hydroxyl radical generating region. The impedance at the hydroxyl radical generating region is controlled to be high to promote creation of an ionisation discharge which in turn generates hydroxyl radicals when water mist is present. The applicator may be a coaxial assembly or waveguide. A dynamic tuning mechanism e.g. integrated in the applicator may control the impedance at the hydroxyl radical generating region. The mist and/or gas and/or energy delivery means may be integrated with each other.

    Abstract: A novel high-speed differential receiver (100) is disclosed that provides a new method and apparatus receiving and amplifying a small differential voltage with a rail-to-rail common mode voltage. The receiver output signals are differential signals with low skew and high symmetry. This high-speed differential receiver (100) is based on a common mode voltage normalization, which is based on a differential phase splitting methodology, before the resulting signal is recombined, normalized and amplified. The method involves using a differential signal splitting stage (110) followed by a common mode voltage normalization stage (130), then a controlled gain transimpedance amplification stage (150), and then amplification using one or two rail to rail amplification stages (170) that are symmetrical and balanced in nature.
