摘要： An electro-optical light scanning system using a modulated laser illumination source directed upon a multi-faceted rotating polygonal mirror or polygon. The mirrored facets reflect the impinging light toward a moving photoreceptor and forms a raster of scan lines as the photoreceptor moves to create dot images on the photoreceptor. The invention also encompasses amplitude modulation for varying the intensity of the laser illumination in conjunction with acousto-optical modulation for maintaining a constant level illumination and/or for varying dot size. Other embodiments describe producing dot size variation in an ink jet printer, a light emitting diode printer and a thermal printer.

摘要： A postage meter includes a printer adapted to print postage and a computer coupled to the printer to account for postage printed by the printer. A power supply is coupled to the computer for energizing the computer to operate. The power supply includes a winding adapted to energize the power supply when magnetic flux is caused to pass through the winding. The power supply further includes a magnetic circuit for coupling magnetic flux to the winding. A housing encloses the postage meter power supply, postage meter computer and postage meter printer. The housing includes a portion adapted to allow the passage of magnetic energy into the interior thereof to energize the magnetic circuit.The postage meter may operate in conjunction with a mailing machine. The mailing machine is adapted to engage the postage meter and includes a power supply system which energizes the mailing machine. The power supply generates magnetic energy and a magnetic circuit cooperates with the power supply to couple the magnetic energy such that when the postage meter is mounted on the mailing machine the magnetic energy will enter the postage meter.The postage meter is of the type which includes a non-volatile memory coupled to the postage meter computer. The non-volatile memory includes a plurality of locations for storing accounting data when said postage meter computer is not energized. The plurality of locations are in predetermined physical locations which are physically assessible. The locations are positioned in the memory so that they can be inspected to determine the orientation of bit patterns therein without electrically energizing the non-volatile memory or physically altering the memory structure.

摘要： An electro-optical light scanning system using a modulated laser illumination source directed upon a multifaceted rotating polygonal mirror or polygon. The mirrored facets reflect the impinging light toward a moving photoreceptor and forms a raster of scan lines as the photoreceptor moves. The system incorporates sensing optics and closed loop electronics for correcting inaccuracies in the position of the reflected light resulting from defects in the angular relationship between the plane of the facets and that of the rotating axis of the polygon as well as those errors due to inherent angular misalignment between each of the facets of the rotating polygon. The invention also encompasses speed control as well as amplitude modulation for varying the intensity of the laser illumination in conjunction with the acousto-optical modulation for maintaining a constant level illumination and/or for varying the spot size.

摘要： A postage scale includes a directly loaded weight-to-period transducer which provides an oscillating output, the period of which varies as a function of the weight to be measured. The transducer includes a disc of piezoelectrically active material bonded to an inactive substrate base which dishes at its center in response to the weight to be measured. The transducer frequency output is processed to provide a digital period signal. A reference oscillator having matched temperature characteristics generates a high frequency count calibrated for scaling the transducer period to a weight count. The high frequency signal and the period signal are gated to provide an input to a counter which generates a digital weight information signal. The weight information signal is transmitted to a mailing system processor for use in determining the postage requisite for mailing the article.

摘要： An electronic postal meter has an accounting unit with redundant nonvolatile random access memories controlled by a microprocessor system. The redundant random access memories have separate groups of address and data lines to minimize identical errors in data stored therein. The data transfer may occur at different times to and from the memories, with respect to any given byte of data. The system may incorporate redundant microprocessors, and critical parameters may be checked at periodic intervals in the main program of the accounting microprocessor system.

摘要： An electronic postal meter system is separated into a meter unit and an input/output control unit. The two units are linked by a communications link which preferably uses light transmitting fibers to transmit data and instructions. The meter unit is used to process and store only that data which pertains to the critical accounting functions of the meter or to the control of the printer driven by the electronics control within the meter unit. Less critical functions, such as zip-to-zone conversions, are restricted to the less secure control unit. By restricting the meter unit to highly critical data and by enclosing only the meter unit in a secure housing, the overall security of the meter system is enhanced. Novel failure detect circuitry for a printer setting detector array and a novel event-indicating signal generator circuit are disclosed. The significant routines employed in the operation of the meter system are described.

摘要： A supplemental printer is mounted piggy-back fashion atop a conventional high speed chain printer or other form of computer output printing equipment; and prints, upon the same print-out sheet as the high speed printer, information generated by the same electronic digital computer to which the high speed printer responds. The supplemental printer is capable of printing postage or other special indicia not easily incorporated into the print symbol repertoire of the high speed printer. In order to make the supplemental printer operate rapidly enough to be compatible with electronic data processing equipment, its print impression is divided into parts printed by individual type segments, each actuated by its own individual print solenoid. Some of the segments are equipped with solenoid-actuated variable numerical print modules for the purpose of printing postage or other variable numerical information. After printing, the segments return to positions at unequal levels in order to deter "wiping off" unauthorized postage or other valuable print impressions.
