An implantable infusion pump possesses operational functionality that is, at least in part, controlled by software operating in two processor ICs which are configured to perform some different and some duplicate functions. A group of concavities are formed in an upper or a lower face of the impeller. Loudspeakers are incorporated in the cover so that the loudspeakers are projected at an upper portion of the main body when the front cover is rotated from the storage position to the open position. The basketball hoop structure is generally disposed within a second plane substantially perpendicular to the first plane when the transportable basketball system is arranged in its play configuration. The soldering sections arranged in the different rows reduce a density of a soldering section layout and facilitate soldering the plug connector to a PCB. The invention further relates to flame-retardant resin composition containing the above flame retardant and its use.
