A method is arranged to segment a surface in a multi-dimensional dataset comprising a plurality of images. The circuit includes a charge pump providing a charge current to a first node, a first capacitor having a fixed capacitance and a second capacitor both coupled to the first node, and an amplifier providing the output signal. The computerized prosthesis alignment system is in communication with a host computer. The control section starts 600 W drive of the lamp heater at time t1 after the control section detects user’s entry into a room, and the control section maintains the 600 W drive during an inrush current reduction period D2. The microlens layer and color converting layer or color filter layer can be disposed for either active matrix or passive matrix, and for either a top-emission type, bottom-emission type, or dual emission type EL display device for improved external light coupling efficiency and brightness.
