Abstract: A hearing aid microphone system includes M microphones providing corresponding electric input signals. Environmental sound at a given microphone includes a target sound signal propagated via an acoustic propagation channel from a direction to or a location of a target sound source to the microphone, and possible additive noise signals. The acoustic propagation channel is modeled. The hearing aid system includes: a processor connected to the microphones, and a database ? having a multitude of dictionaries ?p, p=1, . . . , P, where p is a person index, of vectors, termed ATF-vectors, whose elements ATFm, m=1, . . . , M, are frequency dependent acoustic transfer functions representing direction- or location-dependent, and frequency dependent propagation of sound. The processor is configured to, at least in a learning mode of operation, determine personalized ATF-vectors based on the multitude of dictionaries ?p, the electric input signals, and the model of the acoustic propagation channels.

Abstract: A low reflectivity coating (20) is formed of a layer of carbon nanostructures (20) over a contact surface (14) of a substrate (10), from a spray incorporating the carbon nanostructures in suspension in a solvent. The carbon nanostructure layer provides a very low reflectivity coating which may be further enhanced by etching the outer surface of the coating. The layer may be etched for reduced reflectivity. Very low reflectivity coatings have been achieved.

Abstract: A low reflectivity coating (40, 80/82) is provided on a substrate (22). The coating includes a layer of substantially vertically aligned carbon nanotubes (40) on an exposed surface (21) of the substrate. Provided on and extending partially within the carbon nanotube layer (40) is a hydrophobic coating (80, 82), in the preferred embodiment of or containing fluorocarbon. The hydrophobic coating (80, 82) prevents any settling or ingress of water particles onto or into the carbon nanotube layer (40) and as a result increases the stability of the carbon nanotube layer during use (40) while improving the low reflectivity of the film.

Abstract: In a Chemical Vapour Deposition (CVD) process for forming carbon nanomaterials, a supply of acetylene gas is filtered by a filter to remove a volatile hydrocarbon gas before the acetylene gas is provided to a mass flow controller. The mass flow controller can mix the filtered acetylene gas with a supply of the volatile hydrocarbon gas so that a gas mixture has a selected proportion of the volatile hydrocarbon gas. The filter performs the filtering by passing the acetylene gas over active carbon.

Abstract: An improved isolated current sensing device. The invention consists of two magnetizable cores which surround the conductor carrying the current to be measured. The two cores are cyclically saturated in opposite directions by a high-frequency excitation current counter-wound around the two cores. The device then detects through an output winding the asymmetry in the core magnetic fluxes caused by the current-carrying conductor. The output signal is passed through a phase-sensitive detector tuned to twice the original excitation frequency. Negative feedback is used to stabilize the device.
