Abstract
Abstract A means of defining the anticipated delay until a stopped, automatically restarted elevator car at any of a number of landings will again be running. Signals issued in conventional automatic elevator stopping sequences and characteristic of predetermined instances spaced in time during the stopping sequences are employed to gate portions of a pulse train to a pulse counter. The number of pulses gated is scaled to the anticipated delay so that the count in the counter is indicative of that anticipated delay. Elevator controls can be actuated according to the anticipated delay either alone or combined with other factors characteristic of delays to indicate a car''s availability for service.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
152 words
In an elevator system comprising a car serving a plurality of landings, control means stopping the car at the landings and for starting the car a predetermined interval following the stop of the car, the improvement which comprises means coupled to said control means and responsive to different discrete signals issued by said control means at predetermined times between the stopping setting of said control to stop said car at each of a plurality of said landings and the car stating operation of said control to bring said car to speed; means to initiate an evaluation of the anticipated amount of stopping interval remaining; means responsive to said signal responsive means to generate signals scaled to the anticipated remaining stopping interval and variable indicating means coupled to said signal generating means and said initiating means to indicate the anticipated remaining stopping interval at the time of operation of said evaluation initiating means.
Claim 2
Dependent Claim
152 words
In an elevator system comprising a car serving a plurality of landings, control means stopping the car at the landings and for starting the car a predetermined interval following the stop of the car, the improvement which comprises means coupled to said control means and responsive to different discrete signals issued by said control means at predetermined times between the stopping setting of said control to stop said car at each of a plurality of said landings and the car stating operation of said control to bring said car to speed; means to initiate an evaluation of the anticipated amount of stopping interval remaining; means responsive to said signal responsive means to generate signals scaled to the anticipated remaining stopping interval and variable indicating means coupled to said signal generating means and said initiating means to indicate the anticipated remaining stopping interval at the time of operation of said evaluation initiating means.
Claim 3
Dependent Claim
127 words
A system according to claim 1 wherein said signal generating means is responsive to a first signal characteristic of the early portion of the sequence of said control means bringing said car to a stop and restarting said car at a landing and to a second signal characteristic of the portion of the sequence of said control means bringing said car to a stop and restarting said car at a landing which is later than that characterized by said first signal; and wherein said indicating means when actuated by said initiating means between said first and second signals indicates a relatively long anticipated remaining stopping interval and when actuated by said initiation means subsequent to said second signal indicates a second relatively short anticipated remaining stopping interval.
Claim 4
Dependent Claim
79 words
A system according to claim 2 wherein said signal generating means is responsive to a third signal characteristic of a terminal portion of the sequence of said control means bringing said car to a stop and restarting said car at a landing which is subsequent to that portion characterized by said second signal; and wherein said indicating means when actuated by said initiating means subsequent to said thIrd signal indicates a shorter anticipated stopping interval than said second interval.
Claim 5
Dependent Claim
43 words
A system according to claim 3 including a car door for the car wherein said early portion occurs during deceleration of the car, said later portion occurs while the car door is open, and said terminal portion occurs upon initiation of door closing.
Claim 6
Dependent Claim
73 words
A system according to claim 1 wherein said signal generating means is responsive to a first signal from said control means characteristic of the initiation of slowdown of a car approaching a landing and to a second signal characteristic of the stopping of the car at said landing; and wherein said indicating means when actuated by said initiating means between said first and second signals indicates a relatively long anticipated remaining stopping interval.
Claim 7
Dependent Claim
68 words
A system according to claim 1 wherein said signal generating means is responsive to a first signal characteristic of the stopping of the car at said landing and to a second signal characteristic of the initiation of a car start from said landing; and wherein said indicating means when actuated by said initiating means between said first and second signals indicates a relatively short anticipated remaining stopping interval.
Claim 8
Dependent Claim
76 words
In an elevator system according to claim 1 including a car door for the car and door control means to control said car door position wherein said signal generating means is responsive to a first signal characteristic of said car door being at least partially open; and wherein said indicating means when actuated by said initiating means while said signal generating means is responsive to said first signal indicates a relatively short anticipated remaining stopping interval.
Claim 9
Dependent Claim
30 words
A system according to claim 1 wherein said means responsive to different discrete signals are controls for trains of signal pulses; and wherein said indicating means is a pulse counter.
Claim 10
Dependent Claim
23 words
A system according to claim 1 including means to adjust the magnitude of at least one signal issued by said signal generating means.
