The present invention provides a method of improving the speed of processing of a system and optimizing system performance in RTOS by searching for a task on which occupancy time is the longest in a system mode and transferring a stack from an armored memory to an embedded memory, and by reallocating the stack pointers. The method includes iteratively opening each data file, identifying the selected subset of intensity values associated with each open data file, determining parameters for processing, storing the parameters and the identified intensity values, and closing the open data file prior to the subsequent iteration. The light diverting layer has a first light-diverting surface facing the one or more light sources and a second light diverting surface facing the display panel. Relative alignment is provided between the bobbin and a wire feeder device so that a strand of wire from the wire-feeder device is fed perpendicular relative to a layer of winding that, upon rotation of the bobbin, progressively propagates along the longitudinal axis of the bobbin with a predefined winding angle. A success rate of performing a cell handover by the terminal is improved in embodiments of the present invention.
