Abstract: During manufacturing a unique encrypted authentication code is created for each product 12 based upon device specific information relating to that product 12. The unique encrypted authentication code together with the device specific information is stored in a database 23, and a representation 14 of the unique encrypted authentication code is stored on the product. To determine whether a product in question is authentic, the readable representation 14 of the unique encrypted authentication code is read and sent to a server 22 along with a request for product authentication. The server 22 provides an indication of authenticity of the product 14 in question based upon the unique encrypted authentication code received and the device specific information associated with that unique encrypted authentication code in the database 23.

Abstract: A system (182) for identifying location of a plunger (110) that moves along a length of a well (100), includes an acoustic source (160, 170) carried in the well configured to transmit an acoustic signal when the plunger (110) reaches a sense location in the well (100). An acoustic receiver (184) is positioned at a top (116) of the well (100) and is configured to receive the acoustic signal. Processing circuitry processes the received acoustic signal and provides an output indicative of the plunger reaching the sense location.

Abstract: A process device (100) is configured to meet a desired Safety Integrity Level (SIL). A device interface (310) is configured to couple to the process device and provide an output related to operation of a component of the process device. A component monitor (314) monitors operation of the component with and identifies a safety event of the component. A safety response module (318) responds to a safety event of the component in accordance with a safety response.

Abstract: A process variable transmitter (32) for measuring a pressure of a process fluid includes a sensor module (52), a pressure inlet formed in the sensor module, an isolation diaphragm (90) positioned in the pressure inlet, a pressure sensor (56) and an isolation tube (93, 94) containing a fill fluid to convey a process fluid related pressure from the isolation diaphragm to the pressure sensor (56). A hydrogen getter (222) material is positioned in contact with the fill fluid between the isolation diaphragm (90) and the pressure sensor (56) to remove hydrogen from the fill fluid.
