Abstract: A self-adjusting moistening system for a mailing system is provided. The applicator is coupled to a float mechanism, placed in the reservoir of moistening fluid, by a spring. When the reservoir is full of moistening fluid, the spring is compressed, and therefore does not provide any force on the applicator. As the level of moistening fluid decreases, the height of the float mechanism in the reservoir will also decrease, thereby causing the spring to elongate. As the spring elongates, it will pull down on the applicator, thereby causing an increase in the force applied between the applicator and the wick. This increase in force provides a more uniform deposition of the moistening fluid to the envelope flap as the level of the moistening fluid in the reservoir varies from full to empty.

Abstract: An ink cartridge insertion/extraction mechanism includes a cover pivotally mounted to the housing of the ink cartridge holder. A pair of links are pivotally mounted to the cover and extend into the ink cartridge holder. The bottom of each link is provided with a boss that extends into the ink cartridge holder that contacts the bottom of ink cartridge. As the cover is rotated closed, a pushing rib on the cover contacts the top of the ink cartridge and pushes the ink cartridge further into the holder, causing the needles to puncture the septum of the ink cartridge. To extract the ink cartridge, the cover is rotated from the closed position to the open position, lifting the links until the bosses at the bottom end contact the bottom of the ink cartridge and lift the ink cartridge off of the needles.

A control module interprets the data to provide instructions for the processing of the business reply mail piece based on the recipient's selection.

Abstract: A receiving assembly for an ink cartridge is provided. A replaceable ink cartridge is provided with one or more bosses that extend out from the ink cartridge. A lever is rotatively mounted to a housing for the ink cartridge. The lever includes a curved cam slot. During rotational movement of the lever, the cam slot operatively engages a respective boss and causes the boss to follow a cam formed by the sides of the cam slot. Following the cam form by the cam slot cause the boss to move either upward or downward, according to the direction of the rotational movement, and corresponding movement of the ink cartridge. Downward movement of the ink cartridge will cause a needle mounted to the housing to puncture a septum in the bottom of the ink cartridge, thereby allowing access to the ink contained therein.

Abstract: A system and method for providing secure, on-demand printing of documents delivered to a networked printing device is disclosed. A user logs onto a networked document delivery system using a mobile device and selects a document to be printed along with a networked destination printing device. The document server encrypts and stores the selected document and creates a key. The key is sent to the mobile device. The document server sends a pointer, indicating the location of the document, to the destination printing device. When the user is physically at the printing device, a connection is established between the mobile device and the printing device. The mobile device identifies to the printing device the document to be printed and sends the key to the printing device. The printing device, using the pointer, retrieves the document from the network, uses the key to decrypt the document, and then prints the document.

Abstract: A connection device is provided for meshing of gears on disparate modules, such as those that form a mailing machine. A tongue having a rack can extend from a first module into a cavity formed in the second module. A spur gear is mounted to the second module and can engage the rack of the tongue received into the cavity. A mechanism controls movement of the first spur gear. The mechanism can include a drive gear meshed with the first spur gear and concentrically mounted on one end of a drive shaft with a worm gear mounted concentrically on an opposing end of the drive shaft. Rotation of the worm gear causes the spur gear and the drive gear to rotate and cause movement in the rack received into the cavity and separate or bring together the modules as a result of the movement in the rack.

Abstract: A cryptographic device and method of operation for encrypting messages. The device can be incorporated into a postage metering system to provide cryptographically secured postal indicia. The device and method provide increased security against side-channel attacks such as differential power analysis (DPA). An encryption key is transformed with a first function to generate temporary key as a function of a random number. A message is encrypted with the temporary key to generate a modified message. The modified message is transformed with a second function to generate an encryption. The encryption generated is identical to a direct encryption of the message with the untransformed key. The temporary key is changed frequently to protect against side-channel attacks.

Abstract: The invention is a method and system for printing a postage meter indicia from a data processing system. The printing of the indicia is under control of an indicia control in an object linking and embedding (OLE2) environment. The method begins with instantiating an indicia control in the design application that will utilize the object control for indicia printing. The indicia control is attached to an application window for use by the application. Once established, the control will be passed a set of postage meter data from an interoperatively linked postage meter. The interface is enhanced by displaying an envelope representation on a monitor screen to a system operator, wherein the envelope display comprises design fields and wherein one of the design fields is a representation of the postage indicia. The postage indicia additionally comprises postage meter data such as available funds, a transaction value, and a postage meter identification.

Abstract: A method and method for fast weighing of items such as mailpieces with variable accuracy. The method includes a scale method having a platform connected to a load cell that provides an output signal to an analog-to-digital converter. The resulting digital output signal is processed by a low pass filter and analyzed by a microprocessor to determine weights of items on the platform. The microprocessor also determines postage amounts of items on the platform. The microprocessor also determines postage amounts as functions of the weights and outputs these postage amounts to a postage meter. The microprocessor determines the weights as the average of a sequence of digital output signal values if the average id not closer than D to any weight break, where D is the difference between a maximum output value and a minimum output value.

Abstract: A method and system for generating messages from which it can be verified that a variable does not exceed a predetermined limit. The message can be a postal indicium. A message originator, which can be a postage metering system, receives a message in the form R−k(T), where R is a trapdoor function, K is an integer equal to the limit, and T is a plain text, from a data processing center which maintains the inverse function R−1 in secrecy. The message originator computes Sm=Rm(R−k(T), where m is a current value of the variable, and incorporates Sm into the message. A verifier verifies that m<K by confirming that Rk−m(Sm)=T. The verifier cannot compute Rk−m(Sm) for m<K since it does not have R−1. For the same reason the originator cannot compute R−k′(T), k′>K, from R−k(T).

Abstract: A method and system for printing an image such as a postal indicium. In accordance with the present invention a sequence of graphic data blocks is formed, the sequence forming a bitmap representative of the image. The blocks are randomly reordered to form a new sequence; and the blocks are printed in the new sequence; a printer printhead being positioned and the blocks being printed so as to print the image without substantial distortion. In one embodiment the blocks are printed in varying directions. In another embodiment the printhead moves are at varying rates of travel and prints at inversely proportional rates as the blocks are printed so as to print the image without substantial distortion. In another embodiment the printhead returns to a home position after printing the image.

Abstract: A transport method and system that operates to feed mixed size mail pieces in singular fashion and adaptively controls the velocity of the mail pieces such that overall system performance is optimized is provided. The length of a mail piece is measured and a desired gap time between the mail piece and a subsequent mail piece is calculated. The gap time between the mail piece and the subsequent mail piece is measured, and a difference between the desired gap time and measured gap time is calculated. Based on the calculated gap time difference, the velocity of the subsequent mail piece is adaptively controlled to decrease the difference between the desired gap time and the measured gap time such that the measured gap time is adjusted to be approximately equal to the desired gap time, thereby optimizing throughput of the mailing system.

Abstract: A mailing machine base includes a docking system for a User Interface Controller (UIC) that provides a feedback signal to the mailing machine based on the presence of the UIC. When the UIC is inserted into a docking connector of the mailing machine, the mailing machine detects the presence of the UIC. A delay circuit within the mailing machine provides a signal to a power control circuit after a predetermined time delay. The power control circuit, based on the signal from the delay circuit, will provide power to the UIC only after the UIC has been securely docked for the full predetermined time delay. When the UIC is removed from the mailing machine, the mailing machine, based on the feedback signal, will quickly remove the power provided to the docking connector. Thus, the mailing machine can remain powered during removal and replacement of the UIC.
