摘要:
An elevator includes a car follower (22) associated with each of a pair of guide rails (25), and carrying electromagnets (24) which are spaced from electromagnets (26) on an elevator car (28). The electromagnets on the car and car follower create a repulsive force tending to center the car between the car follower electromagnets associated with the two guide rails. Preferably, the car follower electromagnets are interconnected into a single car follower such that they move together.

A method of representing unscheduled events in a service plan includes retrieving unscheduled service event information relevant to a subject assembly and generating a service plan for the assembly that is responsive to the unscheduled service event information. A system for representing unscheduled service events in a service plan includes a computer system having means for retrieving unscheduled event information relevant to a subject assembly and means for generating a service plan for the assembly that is responsive to the unscheduled event information.
摘要:
A structural integrity monitoring system includes a piezoelectric sensor that is adapted to be secured to or embedded within an item of interest. A resistive element is placed in series with the piezoelectric sensor. An output from the series combination of the resistive element and the sensor is conditioned and then transmitted wirelessly to a remote location. An interface located at the remote location receives the transmitted signal, determines the content of the signal and provides an output indicative of the structural integrity of the item of interest.
