Abstract
Abstract A sensor processor for cooperating with a drive controller in a high-speed mail-handling machine. The sensor processor access periodically a plurality of sensors distributed throughout the machine, and then writes the sensor data to an NVM-RAM shared with the drive controller. Time-critical sensors are accessed more frequently than non-time-critical sensors.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
145 words
In a high speed mail-handling machine capable of processing mixed mail of varying thickness and size, said processing including at least the steps of transporting each mailpiece to a weighing station and weighing each mailpiece and then printing indicia on the weighed mailpiece, said processing being activated and controlled by a drive controller in accordance with a plurality of sensors distributed throughout the machine, the improvement comprising providing a sensor processor dedicated to the task of accessing the sensors to determine their state and communicate the sensor's states to the drive controller, and causing the sensor processor to access the sensors and communicate their state to the drive controller wherein the sensor processor being caused to activate the sensors before collecting their status, and wherein some of the sensors are optical sensors, and the activation step includes measuring the background radiation before collecting their status.
Claim 2
Dependent Claim
