always occur since often times people riding in the car may have significant disparities in size and weight or may be transporting heavy objects furthermore weights which are not an integer multiple of the scaling constant present the system with an ambiguity that must be resolved i e how to round fractional amounts of a person accordingly to address these situations the first embodiment of the sub system 800 of the present invention compares the foregoing first occupancy estimate to the number of different sensors 806 supplying a non zero signal to the summing amplifier 810 as measured by a counter circuit 811 the number of sensors 806 supplying a non zero signal is used as a lower limit on the occupancy estimate additionally the number and disposition of sensors 806 within the car 180 are chosen to provide the sub system 800 with information regarding the distribution of weight therein for example the elevator car 180 of the present embodiment is equipped with sixteen sensors positioned in a 4 u00d7 4 array of four rows and four columns each sensor 806 being centered within its fractional 1 16 th area of the flooring as shown in fig9 assume that the weight of 1500 lbs is distributed within this car of fig9 such that sensors u201c 1 u201d and u201c 2 u201d produce signals proportional to 100 lbs each sensors u201c 10 u201d and u201c 11 u201d produce signals proportional to 110 and 40 lbs respectively and sensors u201c 13 u201d and u201c 14 u201d produce signals proportional to 150 lbs each hence the total weight present in the car is 650 lbs assuming a scaling constant of 150 lbs per person a first occupancy estimate o e of 4 33 persons is produced.
