PCT Application No. WO 98/20461
This invention relates to a system for protecting cryptographic processing and memory resources for postal franking machines. The system provide for faster cryptographic processing and increased security against a successful fraudulent attack. The application discloses placing cryptographic processing and memory resources in a secure processing unit, which may be in the form of an ASIC and is preferably mounted on a portable device such as a PCMIA card. The secure processing unit contains working memory, storage memory, and firmware necessary to execute cryptographic algorithms including DES and RSA, as well as digital signature creation and validation. Information which must be retained, such as Master Keys, Public Keys and the like are secured within non-volatile memory or battery backed up memory.
PCT Application No. WO 97/40480
This invention relates to a system for providing early warning preemptive postal equipment replacement. The system provides for monitoring selected performance parameters of the postal equipment and comparing them against predetermined operational boundaries. The system is capable of providing for variability in the performance parameters, wherein these parameters may be permitted to vary over time and usage of the equipment. If the system performance goes outside of operational boundaries, or changes significantly over time, replacement of the equipment can then be scheduled with minimal inconvenience by the user.
PCT Application No. WO 97/40600
This invention relates to a system for identifying the user of postal equipment. The system provides for a device accessing postal equipment to be associated with a number of access codes, or Personal Identification Numbers (PINs), and the active code being selected at the user's discretion. Additional security may also be provided for by prompting for additional information randomly selected from a predetermined set after the entry of a valid PIN. Data provided to the access device to identify the user may include biometric personal digital data, such as a digital fingerprint, voice pattern or a retina eye scan.
PCT Application No. WO 95/23107
This invention relates to an electronically controlled press feed which feeds material into a stamping press at high speeds. The application discloses several highly innovative individual techniques for increasing the speed at which a press and press feed operate. These techniques include the use of a servo motor formed integral with the shaft of the feed roller; the use of a stock material release mechanism which is infinitely adjustable within working parameters; and determining the discrete angular shaft positions. The shaft positions are determined through the use of computer implemented algorithms. Also disclosed is a single microprocessor based system for controlling the operation of the press feed, which when used to coordinate the individual techniques further increases stable operating speed. Issued patents related to this application include U.S. Patent Nos. 5,755,370 and 5,720,421.
United States Patent No. 5,175,690
This invention relates to a process and device for managing stores. The patent discloses a system for dynamic management of stores, which is contrary to the generally accepted principle that each object should be allocated a particular place. In accordance with the present invention, objects are stored in accordance with sorting algorithms, whose parameters include the dimensions of an object, the dimensions of the storage volumes available in the store, and the shortest distance to a storage volume of appropriate dimensions. A computer controls the system, keeping track of the dimensions of each object in the store, the location of those objects which are present in the store, and the dimensions of the volumes available in the store.
United States Patent No. 5,085,516
This patent relates to a process for determining and monitoring the shape of the edges of a curved object. The patent discloses a process where the position of a curved object is determined at a plurality of points with respect to the edge of a reference. A laser is used to illuminate the edges of the curved object and a reference, and the traces of the laser beam are recorded by a camera. Data derived from the recording is used to compare the monitored object to a standard object.
