A system configured to allow one or more timing processes to accurately keep track of one or more timers while a processor executing the one or more timing processes is in a low-power operational mode. The system permits selective control of display and display features so that complex data and data flows can be seamlessly accessed with enhanced cognition of salient information by a user. More particularly, the present invention relates to the treatment of neurological disorders related to \u03b2-amyloid production such as Alzheimer’s disease and Down’s Syndrome. The filter structure is operable to process said two multi-channel light components of said predetermined polarization to select from each of said two light components the specific channel, and thereby produce two first output light components of the specific channel propagating through spatially separated first light paths. The condenser lens group includes more than one sub lens group. However, if the failure is not overcome, the transformer is switched off for a second time, and six seconds later the transformer is switched on again.
