  • Patent number: 7156290
    Abstract: A system for determining whether a mail piece has been opened including mail pieces that have the ability indicate a previously opened and never opened state, such as with a state change element, an interrogator unit, such as an RFID reader, for receiving state information, and a data center that receives the state information from the interrogator unit. Also, a method for determining whether a mail piece has been opened including receiving mail pieces at a recipient location, receiving at an interrogator unit, such as an RFID reader, state information from the mail pieces, and transmitting the state information from the interrogator unit to a data center. In either the system or method, each mail piece may have an RFID tag that communicates with the state change element and transmits the state information to the RFID reader. Bar code or other technologies may be substituted for RFID technology.

  • Patent number: 6852539
    Abstract: A contaminant detection system for mail is provided. A tray of mailpieces is transported along a transport path into a chamber that has a negative pressure maintained by a vacuum system. The tray of mail enters the chamber and is quickly decelerated, such as, for example, by hitting a stop. The quick deceleration compresses the mailpieces in the tray, thereby ejecting air, dust and other particles from the mailpieces into the surrounding environment inside of the chamber. The vacuum system draws the ejected air, dust and other particles into a sampling system that monitors for the presence of a possible biohazard. If any type of contaminant is found in the ejected air, dust and other particles, the tray can be held for further investigation of the mailpieces. If no contaminants are detected, the tray is accepted and the mailpieces are further processed.

  • Patent number: 6554956
    Abstract: The present invention is directed to an envelope processing system system in which a supply of envelopes is placed for moistening and sealing. The moistening and sealing apparatus is designed to receive all types of intermixed mail envelopes with various shaped flaps. The envelopes may be loaded into the supply station in different configurations including intermixed with closed sealed flaps, unsealed open flaps, or closed unsealed flaps. The system is designed.to receive such envelopes, process them so that the flaps are automatically closed prior to moistening if they are not closed. The flaps of the envelopes are then moistened indirectly using capillary action of a sealing agent, and sealed with a sealing apparatus.

  • Patent number: 5979310
    Abstract: An apparatus and method for printing images. An ink jet printhead forms an image on a transfer roller for transfer to a substrate. The substrate can be an envelope and the image can be a postal indicia. Portions of the image can be interleaved during successive revolutions of the transfer roller to increase the horizontal and/or vertical resolution of the image. A mechanism is provided to deflect the substrate away from the transfer roller after the image is printed so that formation of a new image can begin before the substrate has cleared the print station.

  • Patent number: 5927708
    Abstract: An envelope side guide for a mailing machine includes an elongate support means which is formed to be extendable and retractable in a telescopic manner is connected at one end to a portion of the frame of the mailing machine and supports an envelope guide means on the other end. In one embodiment of the invention, the support means is rigidly connected to the mailing machine frame, and the guide means is mounted so as to be vertically movable on the other end of the support means so that it can be raised above the feed deck of the mailing machine to permit oversized envelopes to be fed into the mailing machine. In another embodiment of the invention, the support means is pivotally connected to the mailing machine frame and the guide means is rigidly connected to the other end of the support means so that the guide means can be raised merely by pivoting the entire side guide assembly upwardly.

  • Patent number: 5862753
    Abstract: An apparatus and method for printing postal indicia and similar images. The apparatus includes two print stations and an ink jet printhead transportable between the stations. The printhead forms images on a transfer roller located at each of the stations and the image is then transferred from the roller to a substrate. At the second station the transfer roller is incorporated in a detachable roller and is used to print remotely located substrates.

  • Patent number: 5723825
    Abstract: An apparatus and method for feeding a mailpiece into and out of a weighing module. The apparatus comprises a device for feeding the mailpiece; and a device for positioning the feeding device in a first position for receiving the mailpiece from a first direction and feeding the mailpiece into the weighing module. Additionally, the positioning device moves the feeding device into a second position for feeding the mailpiece in a second direction out of the weighing module. The feed device includes a drive roller and an idler roller for keeping the mailpiece in operative engagement with the drive roller. The method comprises the steps of: (a) positioning a feeding device in a first position for receiving the mailpiece from a first direction; (b) feeding the mailpiece in the first direction into the weighing module; and (c) positioning the feeding device in a second position for feeding the mailpiece in a second direction out of the weighing module.
