First activation radiation is provided to a sample that includes phototransformable optical labels to activate a first subset of the PTOLs. Record controlling unit 10 controls MPEG encoder 3 and HDD 5 to repeatedly perform this writing process for achieving a continuous recording function. Other exemplary implementations are described herein. The resultant particles retain their small size and are more effective in delivery of nucleic acid to cells in vivo. The skip module skips the stage processing by the stage processors in response to a shutdown command from the controller. Pairing can enable various functions, including an ability to apply stored user preference data to control programming or other information displayed by the output device in response to commands entered in the mobile device.
