Abstract
A system for process control comprises a server digital data processor and a client digital data processor that are coupled by a network, such as the Internet or an Intranet. The server digital data processor, which is additionally coupled to a control/sensing device and any associated interface equipment (collectively, referred to as “process control apparatus”), includes a command processor that transfers information between the network and the process control apparatus. The client digital data processor includes an information client (e.g., a so-called Internet web browser) capable of requesting and receiving an applet from the server digital data processor. The information client, further, defines a hardware-independent and operating system-independent virtual machine environment within the client digital data processor. The client digital data processor executes, within that virtual machine environment, an applet for configuring the client digital data processor as a “process controller” that establishes communications over the network with the command processor and that monitors and/or controls the process control apparatus via those communications.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
