A programmable locating method and system comprises a first electronic device having an actuator, a transceiver, and an integrated circuit. The sensor contains a labeled analogue and a reference, which emit light at different wavelengths. The display includes a screen installed with a cursor thereon and a frame attached to the screen. The thermo-mechanical bender portion further has a base end adjacent the base element and a free end adjacent the free end tip. A multi-shell nanocrystal structure may be formed by preparing a core nanocrystal and reacting the core nanocrystal with two or more precursors having different reaction rates to sequentially form two or more layers of shell nanocrystals having different compositions on a surface of the core nanocrystal. If the individual is allowed, the communication control operation is performed.
