Latest Patents

David J Helffrich holds a patent for an "Insertion machine having multiple document detector." This invention features a multiple-document detection system that includes several document detectors. Each detector is preset to a maximum allowable document-group-thickness measurement. If a group of documents exceeds this preset thickness, the detector's input line changes from a 'normal' level to a 'tripped' level. The processing means then determines the actual number of documents in the group based on which detector was first 'tripped.' This system also includes an expected-number signal sent by a reader, which reads the expected number from a master document. If the measured number exceeds the expected number, an error signal is sent to the machine control means, which executes error-correction steps.
