An electrical connector is used for electrically connecting a ball grid array central processing unit with a printed circuit board. According to an embodiment of the present invention, a common lead is provided such that a plurality of electrical contacts on a fluid-ejecting chip are connected to the common lead, which is located on a single-layer-flex circuit. The distribution of the nanocrystals may be selectively configured to enhance the luminescence efficiency of a fraction of the plurality of nanocrystals that exhibits one energy level mode of the multi-modal energy level distribution. Then, the first data list is modified such that the area where the copy protected data is stored is identified as defective. Further aspects relate to a stretching function presented as one Look Up Table, thus allowing fast computations on limited computing devices such as consumer electronic devices. The activity bitmap includes an entry for each sub extent included in said each extent, said entry indicating an activity level for said each sub extent.
