Abstract
Elevator cars ( ) have floors ( ) including a matrix of elements ( ) including a weight sensing cell ( ) to determine weight distribution in the car for controlling the position of a moveable hitch ( ) on the car and for allocating calls to the cars depending upon the weight distribution. Transmitters ( ) borne by passengers ( ) transmit identification portions, and may also transmit personal preferences of the passenger with respect to the elevator ride. The system may store personal preferences in a data base indexed by personal identification numbers, limiting the required transmission to only the identification number. Correlation (FIG. ) of identification numbers with the cell indicating by weight where a passenger is located may be achieved in each element of the floor or in a controller. A group controller ( ) may allocate calls based upon weight distribution and/or preferences of passengers.
