摘要:
A method and apparatus for printing an image on a print medium using an ink jet print head in an apparatus having an encoder system. The method includes generating a first firing pulse for the print head and starting a timer, waiting to receive an encoder signal from the encoder system and determining whether the timer has reached a preset time limit after the encoder signal is received, generating a second firing pulse for the print head if it is determined that the timer has reached the preset time limit after the encoder signal is received, and waiting for the timer to reach the preset time limit and generating a second firing pulse for the print head when the preset time limit is reached if it is determined that the timer has not reached the preset time limit after the encoder signal is received.

A system for visually presenting data receives signal processing data generated signal processing data collection blocks corresponding to devices associated with a process plant. The signal processing data collection blocks may generate data such as statistical data, frequency analysis data, auto regression data, wavelets data, etc. The system displays an image representative of the devices and representative of a context of the devices within the process plant. Additionally, data based on signal processing data corresponding to one or more devices is displayed. For example, the signal processing data for the device could be displayed. As another example, data may be generated based on the signal processing data and this generated data may be displayed.

A top registration transport mechanism and method for a mailing machine is provided. The transport mechanism includes one or more displaceable rollers that have a diameter larger than the drive/idler rollers. A semi-elastic belt is looped around the drive/idler rollers and displaceable rollers. The larger diameter of the displaceable rollers causes a portion of the transport belt in the area of the displaceable rollers to be slightly raised. The registration plate can contact the raised portion of the belt to displace the belt and displaceable rollers, thereby ensuring that very thin mail pieces can be effectively processed by the transport. As thicker mail pieces traverse the transport, the displaceable rollers can be further displaced before the entire transport mechanism must be displaced to maintain registration of the mail piece against the bottom of the registration plate.

A device for moistening an envelope flap includes a mechanism which defines an envelope feed path and a plate disposed adjacent the envelope feed path. The plate passes between the envelope body and the envelope flap. A plurality of orifices formed in the plate discharge moistening fluid received from a reservoir onto the envelope flap. The moistening device also includes a valve mechanism to selectively supply each of the orifices with moistening fluid from the reservoir. A flap sensing mechanism is disposed adjacent the envelope feed path for sensing an edge portion of the envelope flap and operatively connected to the valve mechanism to supply signals to the valve mechanism to selectively actuate the valve mechanism to selectively supply moistening fluid to the orifices in response to the sensing of the edge portion of the envelope flap.

A method scale system and transducer used in such system for rapid weighing of items. Said scale system includes: a transducer assembly; said transducer assembly in turn including, a transducer having a first member for supporting said item above a reference level, said first member producing a deflection proportional to said weight of said item, a clamping mechanism for clamping said first member to restrict deflection when activated, and a sensor for sensing said deflection and generating a signal representative of said weight as an output signal proportional to said deflection. Said scale system further includes a transport or platform for supporting said item during weighing, said transport being fixed to said first member, and a controller for controlling activation of said clamping mechanism. Said controller controls said clamping mechanism to clamp said transducer as said item is transported into position for weighing so that disturbances of said transducer are reduced and weighing time is decreased.
摘要:
A method for weighing mailpieces while in motion in a mailpiece weighing system. The weigh pan in the mailpiece horizontal transport path generates a signal corresponding to a weight of the moving mailpiece, and the system controller compares the weight of the moving mailpiece to a postal weight break to determine if the postal weight break is within the margin of error of the weighing mechanism. If the postal weight break is within the margin of error of the weighing mechanism, the system controller stops transport of the moving mailpiece and reweighs the mailpiece.
摘要:
A method and method for fast weighing of items such as mailpieces with variable accuracy. The method includes a scale method having a platform connected to a load cell that provides an output signal to an analog-to-digital converter. The resulting digital output signal is processed by a low pass filter and analyzed by a microprocessor to determine weights of items on the platform. The microprocessor also determines postage amounts of items on the platform. The microprocessor also determines postage amounts as functions of the weights and outputs these postage amounts to a postage meter. The microprocessor determines the weights as the average of a sequence of digital output signal values if the average id not closer than D to any weight break, where D is the difference between a maximum output value and a minimum output value.

Systems and methods for providing evidence of printing in metering systems even in the event of a print head failure are provided. Along with generating a primary image for an indicium that evidences payment, a secondary image for the indicium, identical to a corresponding portion of the primary image but at a lower density, with physical boundaries that are within the boundaries of the primary image, is also generated. The primary image is printed by a first nozzle array, and the secondary image is printed by a second nozzle array. Because the primary image completely overlaps the secondary image, the secondary image is undetectable if the primary image is properly printed. The secondary image provides evidence of printing of the indicium that can be used to obtain a refund for the indicium in the event that the primary image was not printed due to failure of the first nozzle array.
摘要:
A pressure transmitter for use in measuring a pressure of a process fluid in an industrial process. The pressure transmitter includes a pressure sensor having a pressure output related to the pressure of the process fluid. Measurement circuitry is configured to calculate a process variable of the process fluid based upon the pressure output. Diagnostic circuitry diagnoses operation of the industrial process based upon a process parameter of the pressure output. Process parameter calculation circuitry calculates the process parameter based upon pressure output and reduces the effect of an abrupt change in the pressure output on the calculated process parameter.
