Abstract: A system for visually detecting unauthorized print value, such as postal indicia on a mail piece. At least one print image is imprinted on a document based upon predetermined relationships and corresponding to a relationship indicator such that the relationship indicator is made known to an authority who may visually inspect the document to detect whether the value was printed by an authorized machine. The relationship indicator may be dependent on valid indicia, geographical location, time of printing, document position, print graphic or like information. The print graphic may also be imprinted in invisible ink for increased security.

Abstract: A programmable telephone/dictation terminal that can be disposed in any one of several different modes of operation including, but not limited to, dictating information onto a recorder, communicating over a telephone network, recording incoming messages received via a telephone line, preventing a telephone dial out operation and communicating "text" messages with a supervisory console. The terminal is provided with several programmable keys each being assignable by the terminal user with a particular function such that, upon the simple operation of that key, the assigned function is carried out. The user may change the function to which a particular programmed key is assigned, as desired.

Abstract: A modular dictation/transcription system is described comprising a modular construction wherein the system is composed of a set of modules which are detachably connectable to each other. Connection or detachment of individual modules from the system configures the system to provide such functions as may be required while deleting such functions which are not necessary. Included within the modules are one or more recording/playback modules a display module and a telephone module. All of the modules interact with each other in accordance with preselectable functions to provide for a more efficient utilization of the dictation/transcription system. Clusters of the modules may be arranged as stations, with the stations connected by a digital communication link.
