Inventor: MANDULEY FLAVIO M
IPC: G01G19/00
Filed: 1993-09-21
Abstract: The method and apparatus for verifying that the correct postage has been paid includes a mail processing machine which is adapted to receive properly oriented mail via a transport from a facer apparatus.  The mail processing machine includes a scale for weighing a mailpiece having postage affixed thereto for the purpose of cancelling it with a mark which includes the actual postage which should be affixed.  In a further embodiment other information necessary to calculate the necessary postage is obtained by reading the information from the mailpiece.  Any discrepancies between the postage affixed and the amount of postage which should actually be paid may be noted at acceptance or seen by the carrier as the mail is delivered. A batch of mail may be sampled to select representative mailpieces in a random manner and verified to compare the calculated total of postage required based on the sample to the postal amount paid for the batch by the sender.

Abstract: A packet switch interface, which may be an asynchronous transfer mode (ATM) layer interface chip, may be connected to the inputs or the outputs of a packet switch. The interface chip modifies the virtual path identifier and the virtual channel identifier in packets directed to and from the switch. The interface chip also manipulates routing tags for the packets which are used for internal routing purposes in the switch. The interface chip includes a local interface through which packets may be extracted from or added to a packet stream flowing between a main input and a main output of the interface. The interface chip polices different communications channels handled in the interface chip by detecting whether traffic in those channels exceeds certain network usage parameters. The interface is also capable of gathering certain statistical information about the traffic in certain communications channels to allow evaluation of network performance. These operations are performed in hardware on a single integrated circuit chip involving a single table look up.  This table look up involves addressing a content addressable memory with a predetermined portion of the header of a packet. Finding a match between the predetermined portion of the packet header and the content of the content addressable memory causes the memory to produce an address signal which acts as a pointer to a location in a random address memory containing a parameter block having data used to perform the operations of the interface.

Abstract: A method for using a telephone system, in order to replace the use  of  existing mail  systems,  for  sending  out  certified  or registered  information.    The  receipt  of  such  information  is acknowledged and responded to by use of this method.  The method involves initiating the call,  recording the substance of certified or registered information, prompting a pre-recorded announcement as soon as the communication is made in order to advise the recipient that the call is being recorded along with the time and date of the call.   After the announcement, the pre-recorded information is transmitted, a record is made of the response, if any, and a full record, including time and date is sent to the initiator of the call.  Alternatively, the "certified" information is spoken by the initiator, rather than being pre-recorded.   In either event, a record of the telephone numbers of the initiator and the recipient are recorded and printed out for transmission to the initiator along with the time and date of the call, and the fact that the connection was made.   Additionally, the record provided to the initiator has the full contents of the "conversation", including the  announcement,  the  intitiator's  words  or  the  prerecorded information, as well as the data mentioned above.
