Abstract: There is provided a method for detecting a machine-readable code that has been applied onto a mailpiece. An exemplary method comprises checking in at least one area of a surface of the mailpiece whether at least two parallel lines are present in the at least one area of the surface, at least two of the parallel lines being at a distance from each other that corresponds to a module width, at least one of the lines having a width that equals the module width. The exemplary method also comprises detecting modules of a data matrix code, in at least one partial area of the surface that is adjacent to one of the lines, taking into account the detection of the at least two parallel lines, the data matrix code having modules of the module width.

Abstract: There is provided a method for detecting a machine-readable code that has been applied onto a mailpiece in a selected area of a surface of the mailpiece, whereby the selected area is at least 1 cm away from at least one nearby edge area of the mailpiece. An exemplary method comprises checking for the presence of at least two parallel lines in the selected area. The exemplary method also comprises beginning a detection of modules of the machine-readable code comprising a data-matrix code at a predefinable distance from one of the lines.

Abstract: Digital franking notes generated in customer systems and comprise cryptographic information that is used for verifying the postage indicia in local payment assurance systems. A data key used for generating the postage indicia is generated in a value transfer center and transmitted via a central payment assurance system to the local payment assurance systems, which import the key in order to verify franking notes generated using the key. The local payment assurance systems notify the value transfer center of successful key imports. After a successful import, the value transfer center issues a data key to the customer systems and postage indicia are verified by decrypting the contained cryptographic information in the local payment assurance systems.

Abstract: The invention relates to a method for verifying the authenticity of a postage indicium generated using a franking key and applied onto a mailpiece, whereby cryptographic information contained in the postage indicium is decrypted and used for verifying the authenticity of the postage indicium. According to the invention the method is characterized in that a data key (KD) is generated and transmitted from a central payment assurance system to local payment assurance systems.

Abstract: Disclosed herein are a method and device for processing postal articles. According to the disclosure, the method includes automatically verifying whether a postal article has an expected prepayment and placing a verification on the postal article where the postal article has the expected prepayment.

Abstract: Disclosed herein are a method and device for processing graphic information located on surfaces of postal articles. Graphic information is detected in one or more processing stations and transmitted to an image processing unit where it is further processed.

Abstract: Disclosed herein are a method and device for processing mail. The method includes checking mail to determine if it has been franked, and if it has not been franked or the franking determined deviates from the franking required, producing and printing on the mail a fee control code. The method also includes sorting the mail according to the fee control code.

Abstract: The invention relates to a method for verifying the authenticity of a franking note placed on a postal article. According to the invention, cryptographic information contained in the franking note is decoded and used for verifying the authenticity of the franking note. The inventive method is characterized in that the reading unit graphically records the franking note and transmits it to a verification unit and in that the verification unit controls a sequence of partial tests.

Abstract: A wheelchair for the disabled and sick in which two rear wheels (1) are each connected to an electric motor drive disposed on the rear axle (2) of each rear wheel (1) and each rear wheel is individually spring mounted in relation to the underframe (5) of the wheelchair by a spring member (6) which is coupled to the underframe (5) and the drive (3). A rocker identically configured for use on the right and left is mounted with its front end in a horizontal axis (8) on a longitudinal bar (9) of the underframe so as to be pivotable with respect to height, and with its rear longitudinal end the rocker is supported on the underframe longitudinal bar (9) and the spring member (6) coupled to the rocker (7). Drive (3 or 4) is attached to the rocker (7). Between the two rockers is a free space (FR) extending from the rear side of the wheelchair to the pivoting axes (8) of the rocker for easy insertion of a battery at the center of gravity.

Abstract: A pin transfer extruder is provided, wherein the pin-barrel and transfer mixing sections, which are known per se and have only been used individually hitherto, are jointly used in one extruder. Throttle pins, which are disposed in the transfer mixing section in the region of the greatest housing thread volume, permit universal use of the extruder in respect of the extruded material. The combination of both mixing systems permits the throughput of material to be increased in a surprising manner by 60% to 100%, while a constant mixing quality is maintained and the driving torque is halved.
