| 20080278328 | MOBILE RFID READER WITH INTEGRATED LOCATION AWARENESS FOR MATERIAL TRACKING AND MANAGEMENT - A portable RFID reader (or reader/writer) that also employs a location determination subsystem that facilitates determination of the reader (or reader/writer) location. The location subsystem can employ a satellite-based GPS (Global Positioning System) location technology where such signals are unimpeded by structures. Additionally, the location subsystem can employ other terrestrial location technologies that operate inside structures such as warehouses and the factory automation environment. | 11-13-2008 |
| 20090206154 | RFID ARCHITECTURE IN AN INDUSTRIAL CONTROLLER ENVIRONMENT - An RFID reader and/or writer module in an industrial controller (e.g., PLC). The RFID module interfaces internally to the controller for tight integration therewith. The RFID module can also be part of a controller communications framework and as a standalone module with the PLC as a master device, and interact with the RFID module in the same manner as it interacts with other I/O devices connected to the controller. In another aspect, RFID read/write tag technology is incorporated into some or all major PLC and rack components, and utilized for wireless communication both between PLC system components and between the PLC and other devices, locations, and media. The RFID tag can be used to store and exchange electronic keying data, security information, module diagnostics and warranty information, series and revision levels code, I/O configuration data, and, replacement data. Artificial intelligence is also employed. | 08-20-2009 |
| 20100123987 | Apparatus for Fault Tolerant Digital Outputs - An output termination board for a safety system is disclosed herein. The termination board provides simplified wiring between the output modules and the remote devices operated by the controller in the system. Redundant output signals are generated within each pair of output modules and combined such that one control signal is sent to each remote device. In addition, a program executing on the controller of the safety system performs a test to determine if each output module is operating normally. If the program detects a fault in either output module, the safety system may alternately shut down according to a fail-safe procedure or continue operating under a fault-tolerant mode of operation. | 05-20-2010 |
| 20100125345 | Apparatus for Fault Tolerant Analog Inputs - An input termination board for use with an industrial controller in a safety system is disclosed herein. The industrial controller may be populated with standard analog input modules according to the requirements of the application. The termination board may selectively receive a single analog input signal from a remote device and transmit the signal to corresponding channels on two analog input modules or, alternately, receive two analog input signals and transmit each signal to one of the two corresponding channels. In addition, a program executing on the controller of the safety module monitors and tests each of the analog input channels on the input modules, verifying proper operation of the modules. If the program detects a fault in either input module, the safety system may alternately shut down according to a fail-safe procedure or continue operating under a fault-tolerant mode of operation. | 05-20-2010 |
| 20100125372 | Apparatus For Fault Tolerant Digital Inputs - An input termination board for use with an industrial controller in a safety system is disclosed herein. The industrial controller may be populated with standard input modules according to the application. The termination board, in conjunction with the controller allows the standard input modules to be used as safety inputs. The termination board provides simplified wiring between the input modules and the remote devices by splitting each of the signals generated by the remote device into separate inputs for two different input modules. In addition, a program executing on the controller of the safety system monitors and tests each of the inputs in both input modules to verify proper operation of the inputs. If the program detects a fault in either input module, the safety system may alternately shut down according to a fail-safe procedure or continue operating under a fault-tolerant mode of operation. | 05-20-2010 |
