A solid dispersion product comprising itraconazole and hydroxypropyl methylcellulose, which satisfies the Formula 0. A computer user interface may be designed for primary use as a 10-Foot user interface, where a user controls the computer using a remote control device, instead of as a traditional 2-Foot user interface where the user controls the computer using keyboard and mouse from directly in from of the computer. The blade body has alternative constructive arrangements in its upper region, having a symmetric or asymmetric spoiler, as well as an alternative constructive arrangement with no spoiler at all, but only a convex bulging, leading to improved distribution of the airflow on the blade. The number of transponders and codes used to transmit each user signal can be readily adapted to user requirements.
