    摘要: In a mailing machine, an image element included in a postage meter indicium printed on a mail piece is transported past a linear image capture device. The image capture device is operated to produce a smeared image of the image element. The smeared image is then automatically analyzed to detect failures in the print elements of a postage meter that is part of the mailing machine.

    摘要: A system and method for detecting abnormal operation of a hydrocracker includes a model to model the hydrocracker. The model may be configurable to include one or more regression models corresponding to different operating regions of the portion of the hydrocracker. The system and method may also determine if a monitored temperature difference variable deviates significantly from the temperature difference variable predicted by the model. If there is a significant deviation, this may indicate an abnormal operation.

    摘要: A system and method for detecting abnormal situations associated with a stirred vessel in a process plant receives statistical data associated with a pressure within a stirred vessel. A pressure signal associated with the pressure in the vessel is filtered by a digital filter to isolate a frequency component corresponding to pressure changes caused by the movement of a blade of an agitator through a fluid. For example, a pressure sensor device disposed at least partially within the stirred vessel may generate the statistical data based on a pressure signal. The statistical data is analyzed to detect whether one or more abnormal situations associated with an agitator of the stirred vessel exist. For example, the statistical data may be analyzed to detect whether the agitator is broken/unbalanced, corroded, missing a blade or multiple blades, etc. If an abnormal situation is detected, an indicator of the abnormal situation may be generated.

    摘要: A method for printing indicia on mailpieces at an increased average speed. The system includes: a postal scale for determining a postage amount for a mail piece; a printer; and a postage meter responsive to the postal scale to control the printer to print an indicium representative of the postage amount. The postage meter further includes: a programmable controller; a secure mechanism for accounting for postage amounts expended; and an indicia generator. The programmable controller is programmed in accordance with the method of the present invention to: respond to a first signal from the postal scale to debit the secure mechanism for a minimum postage amount and to generate an indicium representative of the minimum amount; and, if the determined postage amount equals the minimum amount, respond to a second signal representative of the determined postage amount to print the indicium representative of the minimum postage amount; and, if the determined postage amount is greater than the minimum postage amount, respond to the second signal to debit the secure mechanism for the determined postage amount less the minimum postage amount; delete the indicium representative of the minimum postage amount; generate an indicium representative of the determined postage amount; and print the indicium representative of the determined postage amount on the mail piece.

    摘要: A positive displacement rotary pump including a housing having an internal chamber and inlet and discharge ports, a sealing land on the housing between a downstream end of the inlet port and an upstream end of the discharge port, and a rotating group in the internal chamber defining a plurality of pump chambers. The pump chambers traverse in succession and at regular intervals the inlet port and the sealing land and the discharge port. The housing has a stationary pre-charging passage which communicates with the discharge port and overlaps the sealing land. The rotating group includes a plurality of rotating pre-charging passages which communicate with respective ones of the pump chambers. As each rotating pre-charging passage attains overlap with the stationary pre-charging passage, the low pressure of the fluid trapped in the corresponding pump chamber sealed closed in the sealing land increases rapidly and induces a pulse in the fluid in the discharge port and in the fluid system connected to the discharge port. The angular separation between the rotating pre-charging passages is randomly unequal so that the intervals between pulses are irregular. The irregular intervals between the pulses suppresses tonal pump noise.

    摘要: A system facilitates detecting an abnormal operation associated with a level regulatory control loop in a process plant. A model for modeling at least a portion of the level regulatory control loop may be utilized with respect to first and second signals associated with regulatory control of a level of material in a tank. The model may include a first regression model in a first range corresponding to a first operating region of the level regulatory control loop. The model may be capable of being subsequently configured to include at least a second regression model in at least a second respective range corresponding to at least a second respective operating region different than the first operating region. The model may generate a prediction of the second signal as a function of first signal. It may be determined whether the second signal significantly deviates from the prediction of the second signal generated by the model. If there is a significant deviation, this may indicate an abnormal operation associated with the level regulatory control loop.

    摘要: An image of a moving object, such as a postage indicium barcode on a mail piece, is captured with the object in motion (e.g., while being transported through a mailing machine). An array of CMOS picture elements is held in a reset condition. A signal asserted on control pin ends the reset condition and places the picture elements in an image capture condition. With the picture elements in a picture capture condition, a strobe light is actuated at a time when the barcode is predicted to be present at the picture element array. After the strobe light has been actuated, the signal on the control pin is de-asserted to initiate a read-out of the image data from the picture elements.

    摘要: A system for detecting abnormal operation of at least a portion of a process plant includes a composite model for modeling at least the portion of the process plant. The model may be configurable to include multiple regression models corresponding to multiple different operating regions of the portion of the process plant. A new model may be generated from two or more of the regression models, and the composite model may be revised to replace the two or more regression models with the new model. The system may also include a deviation detector configured to determine if the actual operation of the portion of the process plant deviates significantly from the operation predicted by the composite model. If there is a significant deviation, this may indicate an abnormal operation.
