A battery holder assembly includes a cavity structure, a screw plate, a spring electrical contact, an insulator cup, and a pin. The invention also relates to a detector that can be produced by using said method. By comparing the position of the motion compensated image data in the referenced images with predefined borderlines, impermissible image data positions can be detected and interpolation based on such image data prevented. The saddle-seat comprises a cupped inner volume with a sloped flow channel having an egress spout, coupleable to a drain tube, and the drain tube coupleable to a collection bottle. 55\u201d, where M2 and M3 are the amounts of movement of the second lens unit and the third lens unit respectively during zooming from the wide angle end to the telephoto end in the state in which the zoom lens is focused on an object point at infinity.
