Abstract: This invention relates to a cellular telecommunications systems that utilizes the telephone number the cellular telephone is calling, with the number of telephone calls placed on that cellular telephone, i.e., call count and a seed number to create a digital certificate of the data. The digital certificate is used to make it more difficult to make unauthorized cellular telephone calls. The seed number may be changed after a predetermined number of calls has been made, i.e. one hundred, one thousand, etc. Thus, the transmission of seed numbers between data centers would be substantially reduced.

Abstract: A system for providing items of value, charging the items to a smart card, and for recharging the smart card. The system includes a station for providing the items of value, which may be postal services, and debiting the cost of the items to a smart card; the smart card being charged with funds equivalent data. The station also communicates with a Data Center for recharging the smart card. Users of the system communicate with the data center to request recharge of a particular smart card and in response to an authorized request the data center generates an encrypted authorization message which includes an identification number, the amount of recharge requested, and control data which preferably includes a control sum formed by adding the amounts stored in a descending register, which stores the amount available on the smart card, and an ascending register which stores the total of the amounts by which the card has been charged since initialization. Thus, the authorization message may be used only once.

Abstract: This invention includes a voice response unit that communicates rapidly and directly with a system with minimum human intervention and minimizes the number of retransmissions of information due to errors. The rapid communication is achieved by knowing the question or prompt posed by the voice response unit and preparing a response which is speed dialed to the voice response unit. The voice response unit also examines an error correction code, i.e., Reed-Solomon, to determine if there is an error in the information transmitted to the voice response unit. The timing information enabled the voice response unit to determine whether or not one or more tones are missing from the transmitted information or one tone became two tones. The voice response unit determines if the information it received is correct based upon the error correction code. If, the information is incorrect the voice response unit uses the error correction code to determine and correct certain errors.

Abstract: This device reduces the size of the gap between the apex of the flap opener blade and the drive roller. The above increases the probability that the flap of the envelope would be opened. The foregoing was accomplished by removing segments of the apex of the flap opener blade to allow clearance for the envelope and/or drive roller. Thus, the nominal position of the apex of the flap opener blade was moved closer to the drive roller which reduced the gap between the apex of the flap opener blade and drive roller. Consequently, the chance that the envelope flap would be closed was reduced.

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.

Abstract: An identification card and method and apparatus for producing and authenticating such an identification card. An object or other entity for which the identification card will evidence identity, status or characteristics is scanned to produce a digital signal which is compressed, encrypted, and coded as a two dimensional barcode or as some other appropriate form of coding, which is incorporated into one portion of the identification card. The image is also printed or otherwise embodied onto another portion of the identification card. A text message maybe appended to the signal before it is encrypted and also printed as plain text on the identification card. In one embodiment the signal representing the image is encrypted using a public key encryption system and the key is downloaded from a center. This key maybe changed from time to time to increase security. To facilitate authentication the corresponding decryption key is encrypted with another key and incorporated on the card.

Abstract: A bar code and/or indicia scanning method that is able to determine what light was emitted from an upper layer invisible bar code and/or upper layer invisible indicia and what light was reflected back to the detector from a visible lower layer bar code and/or visible lower layer indicia. The detecting is "blind" to the spectra of the excitation source. Rather than differentiate between the exciter and emitter in the spectral domain, this invention differentiates between the exciter and the emitter in the time domain. The latency and persistence of the phosphorescent pigments of the invisible ink are used so that the detected signal is only the signal emitted by the upper layer invisible ink after the light source is turned off. Illumination and detection are synchronized to reduce the effects of reflection to zero so that the detector need not be chosen to be blind to the exciter. The foregoing is particularly suited to LED and laser illumination where the light source may be easily turned on and off.

Abstract: An envelope inserting machine has a feed path for envelopes which includes an envelope inserting position and means for feeding successive envelopes to that position. Envelope throat opening claw assemblies have claws that maintain the throat of an envelope at the inserting position open to receive a collation of insert material from a collation feeding mechanism adjacent the envelope inserting position. A microprocessor control means actuates the throat opening claw assemblies to release the upper edge of the envelope and substantially simultaneously actuates the envelope feeding means to move the envelope in a rearward direction momentarily, either after the collation is substantially fully inserted into the envelope or while it is still being inserted, to ensure that the collation is inserted sufficiently to bring the trailing edge of the collation beyond the crease line between the front panel of the envelope and the flap.

Abstract: This invention prevents the accounting unit of a postage meter from deducting funds when a mailpiece has been removed. The foregoing is achieved by giving the postage meter the intelligence to stop printing the postal indicia and deducting the value of the postal indicia just before the indicia is printed. This would eliminate the loss of funds due to problems between trip command and actual indicia printing. The apparatus of this invention utilizes a sensor to detect the presence of a mailpiece at a printing position and a detector to determine the location of the indicia printing plate or the time that an ink jet printer is going to print so that the system will be able to prevent the printing of a postal indicia and deducting the value of the postal indicia just before the indicia is printed.

Abstract: This invention utilizes a simple mechanical buffer that will hold material and a two stage software buffering technique that controls the mechanical buffer to act as a First In First Out mechanical mechanism that allows other system events to be triggered off of dynamic thresholds. The two stage software buffering technique consists of a simple software FIFO with rule based logic to control input into a primary queue input and a secondary reserve queue which holds information as soon as it arrives. The decision to move information from the secondary reserve queue into the primary queue is based upon specific rules that are dynamically executed. This permits the creation of a dynamic threshold and allows the reliable triggering of the systems events. The foregoing permits material that is being produced at one fixed speed to be synchronized with material that is produced at variable speeds.

Abstract: The apparatus of this invention is a buffering device for the transport of documents that comprises four variable pitch screws that have a tapered outside diameter and a tapered root diameter at the input portion of the screw.

The upstream screw has its largest outside diameter on the top of the screw and its smallest outside diameter on the bottom of the screw. The downstream screw has its largest outside diameter on the bottom of the screw and its smallest outside diameter on the top of the screw. The screws on the left hand side of the buffering device have a left handed screw thread and the screws on the right side of the buffering device have a right handed screw thread, or visa versa.

Abstract: A method is disclosed for ensuring proper payment by a mailer for postage indicia printed by the postage meter of a mailing machine operated by the mailer. The method includes a series of steps carried out by the mailer in connection with the preparation of a discrete quantity of mail by use of a mailing machine which has the capability of determining and recording in a database various characteristics of the mail that affect the postage required for a postal facility to handle the mail, and generates a product usage profile of the mailer's history of mailing. The Post Office counts the mail, and then calculates an expected cost of the mailing using data from the mailer's product usage profile, and then compares that expected cost with the amount of postage credit funds remaining in the mailer's postage meter to determine whether it is likely that any fraud has occurred in the preparation of the mailing.

Abstract: A method for thresholding a gray scale matrix representative of an image to generate binary matrix representative of the image. Elemental features of the image are determined and characterized, and a plurality of thresholding algorithms is selected. For each algorithm a sequence of binary matrices is generated as scaling factor applied to the algorithm is varied. Features of each binary matrix are determined and characterized and compared to elemental features of the image. For each determined feature which matches a an elemental feature of the image a score is incremented; and for each determined feature which does not match the score is decremented. The binary matrix having the highest score is selected.

Abstract: An envelope is moved along a first path by a first pair of rollers, with the envelope oriented with its lower edge forward, the front panel next to the path, and the flap open. A second pair of rollers is positioned with its nip near the path for capturing the upper edge and flap of the envelope as it clears the first pair of rollers. Preferably the first and second pairs of rollers share a common central roller. A deflector deflects the leading edge of the envelope towards a resilient stop. The stop engages the leading edge of the envelope and urges it back towards the nip of the second pair of rollers. As the upper edge of the envelope clears the nip of the first pair of rollers the force supplied by the first pair of rollers is decoupled from the envelope and force applied by the resilient stop urges the upper edge and flap back towards the nip of the second pair of rollers, which engages the upper edge and folds and seals the flap against the rear panel of the envelope.
