Abstract: Golf training apparatus is provided including sensing means provided on, associated with and/or locatable on or with a golf club in use. At least one target means is provided that is detectable by the sensing means in use. The at least one target means is a target different to a golf ball that the golf club is to hit in use and is locatable separate to and remote from the sensing means and/or golf club in use. The golf training apparatus is arranged to detect the at least one target means and, once detected, use the detected position of the at least one target means to calibrate the sensing means, the apparatus and/or calibrate data being generated by the sensing means and/or apparatus in use.

Abstract: There are many lung diseases and conditions for which the preferred form of treatment involves delivering a medicament of the appropriate sort down the Patient's airways into the lungs themselves. The most effective treatments involve the inhalation as an aerosol of some suitable agent in normally inhaled air, and it will often be the case that it is best to deliver the agent as a “spike” or short pulse at some selected point within the Patient's breathing cycle. The present invention proposes treatment apparatus—specifically and in particular small (pocket-sized) hand-held apparatus—that utilises the “spike” principle.
