In an elevator system, primary marking means, placed near every floors and secondary marking means placed near alternate floors are read by a scanner. Upon scanning, a marking number signal is provided indicating whether a primary marking means and secondary marking means, or only a primary marking means, is read at a floor level. As the car moves in the hoistway, current position, direction of the elevator car, and the marking number signal is continuously updated and stored in non-volatile memory. Upon recovery from a loss of power, the car is moved to the next floor in the direction it was moving prior to loss of power. By comparing the marking number signal stored in non-volatile memory before power was lost with the marking number signal generated after regaining power, the stored position can be confirmed to be correct or, if incorrect, incremented or decremented by one floor, depending upon whether the car was moving up or down respectively, to identify the actual car position.

Method for avoiding terminal landing position initialization after power

A housing (FIG. 2) for an electrical or electronic component which includes a base (10) and an enclosure cap (30), which are held together by a resilient wire-type clip (20) affixed to the base which extends along side of and then over across the top of the cap, compressively holding the cap to the base. The bottom, return leg (20AA) of the clip includes a laterally extended portion (22) at or near the front, side edge (31), from which is suspended a label holder (40; FIG. 3). An adhesively-backed label is affixed to the front display surface (43) of the holder and includes printed indicia indentifying the electrical or electronic component contained within the housing. The clip of wire-like material extends over about eighty (80%) of the width of the sides of the cap in 'zig-zag' fashion and extends diagonally across the top of the cap from near one corner to near the opposing corner.
