Abstract: A system and method for monitoring a structure and for distinguishing between an alarm condition, and a nuisance event such as rain. An optical fibre sensor (20,22) produces a signal indicative of a disturbance and level crossing rates are determined to distinguish between noise in the signal (nuisance event) and a required event. A FFT technique is also disclosed as well as classification of an event by extracting predetermined features from the signal.

Abstract: A device for applying a tactile stimulus, comprising a finger sleeve with one or more raised elements on its outer surface, wherein there is at least one raised element or part thereof in that region of the sleeve defined by the first 15% of its overall length measured from its distal end, and wherein the raised element(s) are arranged in a loop surrounding a blank region of the sleeve which carries no raised elements. The raised element(s) may define a fluid retaining region on the sleeve surface. A region of the sleeve may have a greater flexibility than that of the rest of the sleeve, so as to provide variability in circumference. The device is of particular use in the treatment of female orgasmic disorders and may be used to apply a fluid substance as well as a tactile stimulus.

Abstract: A condom has an erectogenic compound immobilised on the interior surface and substantially at the head end thereof. The compound may be applied as a component of a composition comprising the erectogenic compound dispersed or dissolved in a gel carrier comprising a liquid medium including a thickening agent. The condom may include a lubricant which may be immiscible with the erectogenic compound or composition. Use of the condom sustains e penile erection following spontaneous initiation thereof, to prevent slippage of the condom off the penis while intercourse takes place.
