20150101906 | SYSTEMS AND METHODS FOR PROCESSING BANK NOTES USING A DISTRIBUTED TRACKING SYSTEM - A distributed system for tracking bank notes as they pass through an automated currency processing system is disclosed. The bank note processing system includes a conveyance device for transporting a bank note along a transport path and a detector module comprising a detector. The detector detects raw detector information from the bank note. The detector controller is communicatively coupled to the detector module and the raw detector information is communicated to the detector controller. A host controller is communicatively coupled to the detector controller. The detector controller processes the raw detector information to determine processed detector information. The detector controller then communicates the processed detector information to the host controller. | 04-16-2015 |
20150016948 | LINEAR PUMP CONTROL - A demand-based load balancing function may be provided by one or more drive controllers that takes advantage of the affinity laws to linearize the control of the variable of interest (e.g., flow, pressure, etc.). Each drive controller may be set up by the user simply inputting a few values into the drive controller. Based on the inputs, the drive controllers may interpolate control points using an assumed linear relationship between the variable to be controlled (e.g., pressure) and the current driven to the pump. Feedback data from the system may be used to continually update the drive controllers so as to potentially allow them to better balance power usage to each pump. | 01-15-2015 |
