  • Patent number: 5539852
    Abstract: A method for controlling the speed of a motor for a tape drive in a mailing machine includes providing an optical sensor for signaling the appearance of slots in a slotted wheel connected to the motor shaft. The time intervals between slots are used to make a prediction in respect of expected future time intervals and the motor speed is adjusted in accordance with the predicted value to obtain the desired value. For best results, the data is received at the microprocessor using the "capture" mode of operation in order to avoid excessive errors due to a "busy" processor. The invention enables the small motor of a tape drive to avoid over and undershoot even when operating under highly variable load conditions.

  • Patent number: 5448641
    Abstract: A data center provides a rate table to a user. The rate table is communicated to the mailer along with a hash code that is based on information from the rating table. The hash code provides a unique number based on the rating table. The user within a secure device and to which the rate table is loaded regenerates the hash code based on the information received from the rate table and compares the transmitted hash code with the generated hash code. The comparison verifies that the rate table data has not been intentionally or unintentionally corrupted. The transmitted hash code may be encrypted by the data center and when received decrypted by the mailer. The encryption decryption process provides authenticity of the data center if desired. The generation of the hash code and the comparison with the transmitted hash code can be initiated prior to postage printing and used to insure proper rating. Printing is enabled only after the rating process has been properly implemented.

  • Patent number: 5427025
    Abstract: A flat bed printing mechanism for a postage meter is disclosed which includes a flat printing die, a platen mounted beneath the printing which is movable toward and away from the printing die to as to bring the image area of a mail piece disposed over the platen into printing contact with the printing die. The platen supports a resilient pressure pad which contacts the mail piece, and there is a resilient means interposed between the upper surface of the platen and the lower surface of the pressure pad to support the pressure pad in spaced relationship with the upper surface of the platen so that the pressure pad is free to move both linearly and angularly with respect to the platen when the platen moves upwardly to press the mail piece against the printing die, to cause the plane of the upper surface of the pressure pad to conform to the plane of the image area of the mail piece as the platen pushes the image area of the mail piece upwardly toward the printing die.
