Abstract: The processing system controller is utilized in a mail processing system. The processing system controller provides process control over a plurality of processing subsystems which operate on a mailpiece traversing the processing system. The processing subsystems employing a plurality of prime movers controlled by the processing controller. The processing system controller includes a motor controller in bus communication with the prime movers for control of the prime movers. Sensors monitor the operating conditions and parameter of each subsystems and are in bus communication with a sensor controller. A random access memory (RAM) is in bus communication with the motor controller and the sensor controller. The motor controller and the sensor controller are programmed such that the motor controller can read from the RAM and the sensor controller can write to the RAM. The motor controller reads from the RAM at discrete time intervals and the sensor controller writes to the RAM at other discrete time intervals.

Abstract: Improved Driver circuitry for multiple combination LED/silicon detector sensors arranged in an array or scattered in a machine, wherein the LEDs and detectors are connected in a matrix arrangement to common busses to reduce the number of connections and minimize interference. Grounding gates are toggled "ON" and "OFF" prior to actuating the driver circuitry to reduce the presence of live voice.

Abstract: The motor controller system controls the respective motors of a plurality of cooperative apparatus associated with an article processing system, the article processing system for performing a plurality of functions upon an article traversing the article processing system and comprises a motor driver board having a plurality of input channels and a plurality of respective output channels. The motors are in line communication with a respective one of the output channels of the motor driver board. A programmable microprocessor is in bus communication with the driver board's input channels. A plurality of sensors are respectively mounted to each of the apparatus and in bus communication with the programmable microprocessor, the sensors being strategically located on the apparatus to provide such information to the microprocessor as article size, position and velocity information and to provide apparatus operation information.
