Techniques to determine when to decrease a frame display rate based in part on the amount or degree of change between sequential frames. If more than two layers are to be made, additional stations are employed further along the conveyor belt. One exemplary application of the described concepts is in cooling electronic components in computers, for example personal computers or server computers. In another embodiment, the electronic device includes a microprocessor, a plurality of internal peripherals, an interconnecting component, an external coupling port, and a memory for storing instructions. A lithium polymer battery using the polymer electrolyte composition can be suppressed from danger of ignition or explosion when the battery is overcharged due to some uncontrolled conditions, such as failure of a charger. More specifically, electrically pixelated luminescent devices that have inner and outer semiconductor layers and a continuous light emitting region, as well as individually addressable electrodes are described.
