A system for substantially automating transcription services for multiple voice users including a manual transcription station, a speech recognition program and a routing program. The system establishes a profile for each of the voice users containing a training status which is selected from the group of enrollment, training, automated and stop automation. When the system receives a voice dictation file from a current voice user based on the training status the system routes the voice dictation file to a manual transcription station and the speech recognition program. A human transcriptionist creates transcribed files for each received voice dictation files. The speech recognition program automatically creates a written text for each received voice dictation file if the training status of the current user is training or automated. A verbatim file is manually established if the training status of the current user is enrollment or training and the speech recognition program is trained with an acoustic model for the current user using the verbatim file and the voice dictation file if the training status of the current user is enrollment or training. The transcribed file is returned to the current user if the training status of the current user is enrollment or training or the written text is returned if the training status of the current user is automated. An apparatus and method is also disclosed for simplifying the manual establishment of the verbatim file. A method for substantially automating transcription services is also disclosed.

A warning utility function is derived based upon a combination of the filtered pressure and leak rate.

An absolute pressure sensor includes a sense die with a reference chamber on a top side thereof. The reference chamber comprises a precisely fabricated beam that limits the travel of a diaphragm. The beam can be positioned in a cap or cover member of the sense die, thereby allowing the sense die diaphragm to move freely for a particular distance. Over this distance, the sense die will have one sensitivity. When the sense die is pressurized to a certain point, the diaphragm moves until it contacts the beam member in the cap or cover. When the diaphragm hits the beam, the sensitivity of the sense die changes, thereby allowing a smaller voltage out for the greater pressure in. Such an arrangement permits the sensor to provide a function that accurately measures low pressure and measures a higher pressure without utilizing a linear scale.
