摘要： A system and method for weighing of items such as mailpieces in the presence of external vibration such as ground noise. The system includes a scale system having a platform connected to a load cell, which 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 as functions of the weights and outputs these postage amounts to a postage meter. The microprocessor determines the weights as the median of the peak to valley difference of the digital output signal when the digital output signal peak to valley difference is less than a predetermined value. The microprocessor identifies peaks and valleys of the digital output signal by determining when the derivative of the signal changes sign. The microprocessor estimates the weight as an average of a sum of medians for N preceding cycles if the digital output signal does not converge.

摘要： A postage meter mailing machine includes a multiplex serial data communication system for providing communication between the postage meter mailing machine and a plurality of internal and external devices. Each device can generate and receive serial messages at a respective device communication port. The mailing machine includes a controller, a UART controller module responsive to control signals from the controller, a message buffer in bus communication with the UART controller and a communication multiplexer. The communication multiplexer provides single channel communication with the UART controller module and selectively with one of a number of external communication ports. The communication multiplexer is responsive to control signals from the controller for establishing a communication path between the UART controller module and the selected one of communication ports over the single channel communication and sequentially alternating the communication path between each of the communication ports. Each communication port of the communication multiplexer is directed to a respective one of the device communication ports. The UART controller module can determine whether a serial message data is presented at a respective one of the communication ports and maintaining communication between that communication port and the single channel communication. Messages are directed to and from a buffer until the messaging is completed in the message buffer. When the messaging is complete, the communication multiplexer resumes its cycling between the various communication ports.

摘要： A motor controller is programmed for detecting motor-stall condition of a dc motor under the control of a motor control system. The motor control system includes a programmable microcontroller in connection with the motor controller and a motor driver. The motor driver communicates with a dc motor. The dc motor is coupled to a position encoder which encoder is in communication with the microcontroller. The method comprises the steps of providing an average stall threshold value ASV and providing the motor controller with a time counter for counting each time interval T to a maximum count N. The motor controller is programmed to issue a motor command representing the position error between the desired motor position and the actual motor position for some time interval T. During each time interval T, the motor command is compared to the average threshold value ASV, if the motor command is greater than the ASV then the count in the time counter is compared with the maximum count N. If the count is equal to the maximum count N then the controller signals the microcontroller a "motor stall" fault. If not, the motor is "OK" and the method is repeated for the next time interval T.
