A method to improve performance of an SRAM cell or an SRAM array comprising a plurality of SRAM cells is described. An optional metal silicide layer can be formed on the polysilicon layer. The reference detector is read multiple times during the frame period in which the image sensor array captures a scene to detect illuminant intensities during the same frame period. The pivot shaft is oriented parallel to the measuring tape axis. Once the capsule is inserted into the compartment, it will be sufficient to activate the cutting device, then place the mouthpiece into the mouth and breathe in, so that the powdered substance dispersed into the chamber can reach the lungs.
