Patent ID: 8534426

Claim:
An elevator controller for controlling an elevator system having at least one elevator car for vertically conveying passengers, said elevator controller (a) programmed to operate said at least one elevator car to move vertically without pressure differential experienced by a passenger's ear exceeding a maximum pressure differential value; and (b) programmed to simulate an elevator trip between an initial location and a destination location for at least one elevator passenger, to calculate a pressure differential value representative of the pressure difference between a passenger's middle and outer ear at one or more points during the simulated trip, and to establish values for one or more of the speed, acceleration or jerk of the elevator car during the simulated trip so that the calculated pressure differential value does not exceed the maximum pressure differential value as the elevator car travels from the initial location to the destination location during the simulated trip, and to operate the at least elevator car in accordance with the established values.
