    Abstract: A computer implemented method of decoding a signal. The method includes receiving a signal (which may be an electromagnetic signal), sampling the received signal to generate an input waveform having magnitude and phase components, applying a transform operation to the input waveform to generate a first decoded signal, and outputting the first decoded signal. The transform operation includes pre-processing the input waveform to generate a mirrored inverted waveform and applying a continuous wavelet transform to the mirrored inverted waveform to generate the first decoded signal. This allows inversion of the frequency and temporal resolution of the continuous wavelet transform, thereby enabling improved temporal and frequency decoding of a signal. The method is particularly suitable for signal filters and filtering units.

    Abstract: A sensing element is provided for use in a system for measuring fluid flow, such as, turbulent air flow. The sensing element comprises a sensor body and a first load cell arrangement connected to the sensor body. The sensor body has a three dimensional shape which is rotationally symmetric about a longitudinal axis passing through the first load cell arrangement and the sensor body. The first load cell arrangement is configured to measure the force exerted on the sensor body by fluid flow in at least an xy plane perpendicular to the longitudinal axis. A system for measuring fluid flow comprising the sensing element and a method for measuring fluid flow using the sensing element and the system are also provided.

    Abstract: This invention relates to a device for rapid focus control of one or more lasers. The controlled beam (5), is refracted by the dynamic refraction device (1) whose refractive index is set by its response to the control beam (3). The invention can be used for rapid focus and re-focus of a laser on a target as might be useful in such industries as flat panel television manufacturing, fuel injector nozzle manufacture, laser material processing/machining, laser scanning and indirect drive inertial confinement fusion.

    Abstract: The invention provides an airborne passive decoy system for use in the radio waveband, the system comprising a controllable aerial propulsion unit and one or more retroreflectors, wherein the one or more retroreflectors are mounted on, contained within or otherwise borne by the controllable propulsion unit, and wherein the system is configured such that the one or more retroreflectors can be deployed as a decoy at a desired location and/or time. The system is an integral system which does not rely on tethers, cables or suchlike. Related methods and uses are also provided.
