摘要： Elevator brake or other drag is checked by establishing (10-13) baseline motor currents at plural determined positions as the car is moved up and down both empty and with full load. In a normal run (21), the load is recorded (22) and the motor current required to drive the load at rated speed at the next determined position is both predicted (28) and measured. If the difference between the predicted and actual current exceeds a tolerance (33, 34), the car stops at the next floor (35), the system is shut down (39) and a message generated (40). When the brake is in proper operating condition, baseline motor current required to move a car with the brake engaged is recorded. Thereafter, a high fraction (such as 90%) of baseline motor current is applied to attempt to move the car. If the car moves, the system is shut down (101) and a message generated (102).

摘要： An exemplary method is useful for controlling movement of an elevator car in an elevator system that includes a machine that selectively moves the elevator car and a machine brake that selectively resists movement of the elevator car. The method includes determining whether the elevator car is near a landing and determining whether a door of the elevator car is open. A desired operation includes desired movement of the elevator car while the elevator car is near the landing and the door is open. A determination is made whether the elevator car moves other than according to the desired movement. The machine brake is applied for stopping movement of the elevator car responsive to elevator car movement other than the desired movement while the elevator car is near the landing and the door is open.

摘要： A roller apparatus is provided. The roller apparatus may include a bearing wheel configured to rotatably couple the roller apparatus to a roller shaft, and a resilient member radially disposed about the bearing wheel and configured to contact a guiderail at different magnitudes of loads. The resilient member may include a first section of a first diameter and a second section of a second diameter. The first section may be caused to deflect in response to loads within a first load range, while the second section may be caused to deflect in response to loads within a second load range. The resilient member may exhibit a stepwise increase in stiffness with a gradual increase in load.

摘要： A system for aligning a semiconductor wafer with a mask bearing a pattern to be formed on the wafer, in which both the wafer and the mask bear an alignment mark, and in which light used for alignment is filtered to transmit only in a selected bandwidth, uses a reflector system to gather light reflected from edges of the alignment mark on the wafer. In order to minimize the effect of erroneous alignment signals from standing waves generated when the alignment signal is reflected from a wafer coated with a layer of photoresist, a second filter is placed in the path of light after it has reflected from the target. This second filter transmits a range of the reflected light which does not produce standing waves.

A mounting member is configured to mount the brake device to a stationary surface. The mounting member is at least partially moveable relative to the stationary surface responsive to a torque on the brake device. A sensor provides an indication of a force associated with any movement of the mounting member relative to the stationary surface responsive to the torque.
