Abstract
A system for automatically setting a postage meter as a function of package weight and destination includes a scale mechanism for generating weight-representing signals. The package postage can be established by converting the destination zip code to a destination zone. The destination zone used in retrieving a minimum postage and incremental postage amounts is applicable for that zone from data storage. The weight-representing signal is successively decremented and the postage amounts synchronously incremented until a signal checking circuit establishes that the decremented weight-representing signal is equal to zero.
Claims6
A method for converting a postal zip code to a postal zone, of a given destination, comprising the steps of;
- (a) storing a sequence of delta zip numbers, wherein a delta zip number is an absolute number corresponding to the number of postal zip numbers in a sequential group corresponding to a common destination zone;
- (b) storing a sequence of postal zones corresponding to the sequence of storage delta zip numbers;
- (c) sequentially decrementing said postal zip number to be converted by absolute numbers in accordance with said stored sequence of delta zip numbers, until a determined numerical value occurs;
- and
- (d) then retrieving the corresponding zone in said sequence of postal zones.
A method for converting a postal zip code to a postal zone of given destination, comprising the steps of storing a first sequence of numbers corresponding, in order, to the absolute numbers of zip code numbers in groups of adjacent ascending sequential postal zip code numbers which correspond to a common postal zone number, storing a second sequence of the numbers of said postal zones in the order that they correspond to said groups of zip code numbers, selecting a zip code number, decrementing said zip code number by said absolute numbers in said order until a given result is attained, and retrieving the postal zone number of said second sequence corresponding to the absolute number of times said selected zip code number has been so decremented.
A method for preparing a parcel for mailing comprising storing a first sequence of numbers corresponding, in order to the absolute numbers of zip code numbers in groups of adjacent ascending sequential postal zip code numbers which correspond to a common postal zone number at a given location, storing a second sequence of the numbers of said postal zones in the order that they correspond to said groups of zip code numbers, selecting the zip code number of the destination of said parcel, decrementing said zip code number by said absolute numbers in said order until a given result is attained, retrieving the zone number of said second sequence corresponding to the absolute number of times said selected zip code number has been so decremented, determining the postage for mailing said parcel to said destination on the basis of said retrieved postal zone number, and affixing said determined postage to said parcel.
