Operation of an industrial vehicle, such as one that lifts and transports loads, is controlled based on the weight of a removable battery. A control method involves reading a battery weight value from an electronic memory attached to a battery. That battery weight value is compared to a specified battery weight value for the industrial vehicle. The operation of the industrial vehicle is restricted to less than the normal operating characteristics when the battery weight value is less than ...

A separation distance is maintained between a leading elevator car (14) and a trailing elevator car (12) traveling in the same direction in an elevator hoistway (16). A shortest stopping distance (d_ssl) of the leading elevator car (14) and a normal stopping distance (d_nst) of the trailing elevator car (12) are determined. The separation distance (d_sep) is controlled such that a difference between the normal stopping ...
