A controller is configured to perform in-situ testing on a control valve. These configurations can generate a signal that changes position of a closure member in the valve during operation of a process. These changes exercise components of the valve for a short period of time. This testing may result in data that can indicate whether the device is operating properly or may be in need of maintenance or repair.

Testing control valves in the field

Embodiments of methods that are useful to avoid overflow in fixed-length buffers. In one embodiment, the methods dynamically adjust parameters (e.g., sample time) and reconfigure data in the buffer to allow new data samples to fit in the buffer. These embodiments allow data collection to automatically adapt, e.g., by adjusting the sample rate to allow the data to fit in the limited buffer size. These embodiments can configure hardware and/or software on a valve positioner of a valve assembly to improve data collection for use in on-line valve diagnostics and other data processing techniques.

Method of sampling and storing data and implementation thereof

In some speech recognition applications, not only the language of the utterance is not known in advance, but also a single utterance may contain words in more than one language. At the same time, it is impractical to build speech recognizers for all expected combinations of languages. Moreover, business needs may require a new combination of languages to be supported in short period of time. The invention addresses this issue by a novel way of combining and controlling the components of the single-language speech recognizers to produce multilingual speech recognition functionality capable of recognizing multilingual utterances at a modest increase of computational complexity.

Method of multilingual speech recognition by reduction to single-language recognizer engine components

A method of constructing a list of alternate transcripts from a recognized transcript includes generating a list of close call records, matching partial sub-histories from the recognized transcript with one of the history pairs stored in each of the records, and substituting the other of the history pairs for the partial sub-history of the recognized transcript. A close call record is generated each time a pair of partial hypotheses attempt to seed a common word. Each close call record includes history information and scoring information associated with a particular pair of partial hypotheses seeding a common word. Alternate transcripts are constructed by substituting close call histories for partial histories of the recognized transcripts, and also by substituting close call histories for partial histories of other alternate transcript.
