    Abstract: A golf practice unit simulates a sand bunker so that the user may practise playing golf shots out of it on to a simulated green 1. The landing area 1 is at such a slope that any ball landing and missing a target 3 will roll back towards the player and rest in a collecting tray 6, to be used again. An adjustable wall 4 may be provided between the bunker and the landing area 1.

    Abstract: Photodarkening resistant optical fiber lasing media and fiber lasers incorporating the same are disclosed. In one embodiment, an optical fiber lasing medium includes a core portion formed from silica-based glass comprising a rare-earth dopant and deuterium, the core portion having an index of refraction n c , a numerical aperture NA c . A concentration of defect color centers in the core portion is less than 1x10 16 /cm 3 . Deuterium is combined with the defect color centers to form reacted defect color centers that do not absorb ultraviolet and visible wavelengths of light. A first cladding portion is formed from silica-based glass, the first cladding portion surrounding and directly contacting the core portion and having an index of refraction n 1 , wherein the index of refraction n 1 of the first cladding portion is less than the index of refraction n c of the core portion. Methods of forming the photodarkening resistant optical fiber lasing media are also disclosed.

    Abstract: A positioning method that calculates a lower accuracy positioning solution and applies an offset to the lower accuracy positioning solution to form a final positioning solution if a higher accuracy positioning solution is unavailable. The offset represents a difference between the lower accuracy positioning solution and the higher accuracy positioning solution at a point in time when the higher accuracy positioning solution was last available.
