Latest Patents

Lewis's latest patents include a "Method and device for wavelet denoising." This invention provides a digital receiver arrangement that comprises a tuner/demodulator circuit and an analogue-to-digital converting means. It also includes means for storing an impulse wavelet representation and determining if an interference impulse is present in a received signal. The invention introduces the stored representation of the impulse wavelet to a detected received impulse to counteract its effect within the received signal. Another significant patent is "Measuring radio-frequency impedance." This method and apparatus derive radio-frequency impedance information of an electrical network, such as an aerial. It utilizes a current converter to induce a radio-frequency current into the network and a voltage converter to impress a radio-frequency voltage on the network. By applying radio-frequency signals to the converters, the resultant signals present in the network can be detected, allowing for the derivation of impedance.
