Title: Multi-slot call relocation control method and system
Inventor: HAMAGUCHI NAOHISA
IPC: H04L5/22
Filed: 1990-09-18
Granted: 1994-01-25
Abstract: ABSTRACT OF THE DISCLOSURE    A multi-slot call relocation control method and system having a multi-slot call switching system and/or transmission equipment constituted by an address control memory, address controller and address location changing circuit whereby address write and read information for a channel memory is controlled. Where unoccupied circuits are 2N (N: natural number) times the basic switching unit, incoming calls with a maximum of 2N basic switching units in capacity may not be switched or transmitted by the unoccupied circuits depending on their status involving the presence of other calls. In that case, calls are relocated within a frame using the fewest steps possible.          This is achieved by a neural network in the address control memory of multi-slot call switching system A, the neural network learning to output a call allocation pattern such that the number of times calls are relocated becomes minimal. The information from the network makes it possible to relocate the least number of times the calls whose capacity is not more than 2N basic switching unit in the channel memory. The relocation information is transmitted from switching system A to another system B, connected oppositely to system A. Using the relocation information received, system B relocates calls within A channel memory of its own.

Title: Method and apparatus for a mail processing system
Inventor: BAKER CHRISTOPHER A
IPC: G07G5/00
Filed: 1990-10-16
Granted: 1999-12-07
Abstract: Mail handling or processing systems are disclosed wherein the entire lot or batch of mail pieces is loaded into a bin for processing. Each mail piece is individually removed by an operator while the computer monitors the weight of the bin and simultaneously produces serial numbers for affixing to each mail piece. In an alternative embodiment a postage meter provides postage imprinting and labelling for each mail piece removed. By monitoring the tare weight difference of the bin prior to and after removal of each mail piece, the mail piece weight is determined from the difference between the two tare weights. The weight of each mail piece is required in order to determine postage cost or mail charges for each mail piece.      After all pieces of mail are removed from the bin, an operator can optionally key the system to produce a postal service form complying with manifest mailing requirements.      The computer also produces a manifest including serial numbers and mail charges related to each serial number marked mail piece and a manifest summary.      In an alternate embodiment, the bin is loaded one by one with each mail piece while a computer simultaneously monitors the weight of the bin as each mail piece is added, serial numbers are produced for affixing to each mail piece, and the computer links each serial number with a weight deviation thereby calculating mail charges for each mail piece and storing the information for reproduction in summary form in a mailing manifest.
