Abstract: A receiver and associated methods are described. The receiver comprises a first oscillator 14, a second oscillator 16, a controller 18 operable to control frequencies to which the first and second oscillators are tuned, and a discrimination circuit 24 operable to receive and monitor transmitted signals; wherein the discrimination circuit is configured to receive a signal at a first transmission frequency determined based on a first tuned frequency to which the first oscillator is tuned, and to determine, in a capture time period, whether data is being transmitted at the first transmission frequency; wherein the controller is configured to tune, in a tuning time period, the second oscillator to a second tuned frequency; and wherein the tuning time period is shorter than the capture time period.

Abstract: An aperture plate is formed from a palladium nickel alloy comprising about 89% palladium and about 11% nickel. There is a generally fine substantially equiaxed grain microstructure throughout the thickness of the aperture plate. The average grain width (W) is in the range of from 0.2 ?m to 5.0 ?m, in some cases from 0.2 ?m to 2.0 ?m. Because the grain structure is equiaxed (L/W=1) the grain length (L) is the same as the grain width. The improved aperture plate extends the life of nebulisers, eliminates the risk of premature and unpredictable failure of a nebuliser in service, eliminates the risk of product returns from hospitals and patients, and eliminates the possible risk of fragments of the aperture plate breaking free from the nebulizer.
