Abstract: A mechanical convergence fixture apparatus (10) having an LCD frame assembly (12) which is positioned in relation to a projector chassis (14) using an alignment assembly (12) which is positioned in relation to a projector chassis (14) using an alignment assembly (16). The LCD frame assembly (12) has a micro LCD (24) rigidly affixed thereto and a field lens (32) adjustably affixed thereto. A vacuum chuck (40) holds the LCD frame assembly (12) on the alignment assembly (16) while the LCD frame assembly (12) is positioned. A drop of adhesive (62) is then placed on each of a plurality of locating studs (18) and a like plurality of locating holes (20) to affix the LCD frame assembly (12) in position on the chassis (14). The alignment assembly (16) is then detached from the LCD frame assembly (12) to be reused.

Abstract: An elevator system includes a control system that determines the amount of load of the car, and that determines the operating speed profile of the car based upon the amount of load in the car. In a particular embodiment, the control system includes a load weighing device and uses the weight of the car to determine the selection between two operating speed profiles: a normal operating speed profile and a reduced operating speed profile. The control system compares the measured live load to a pre-selected threshold, such as the car weight plus twice the percentage balancing multiplied by the rated full load of the elevator system. If this threshold is exceeded, then the reduced operating speed profile is selected. In this way, reduced balancing may be used. The selected percentage balancing may be determined empirically or estimated by taking into account the building size, usage and other operational characteristics.
