Abstract

An intelligent printer-plotter for use with a source of time-correlated digital systolic and diastolic blood pressure data and heart rate data receives, stores, analyzes, and edits the data, producing tables of data and graphs having a particular format. The charter smooths the data by a moving average technique and includes modes which permit the operator to edit the data manually or to command the charter to perform the editing automatically. In the automatic editing mode, the data are tested against pre-established criteria. Data not meeting the criteria is flagged so that it can be passed over in subsequent calculation and printing operations; however, the flagged data is not destroyed, but is retained in a memory to permit subsequent re-examination and to permit verification of the editing process.

Dependent claims

A charter for use with a source of time correlated digital systolic and diastolic blood pressure data and heart rate data, for receiving, storing, analyzing, and editing the data, and for producing tables and charts having a particular format for displaying under control of an operator in edited and unedited form both the data as received from the source and the analyzed data, said charter comprising in combination:

first storage means connected to the source of data for storing words of data when they are received from the source of data, and including flag storage locations associated with each of the words of data for storing as required a flag along with each word of data;
automatic editing means connected to said first storage means and operable in response to an edit command to edit by testing stored words of data to determine whether the stored words of data meet certain pre-established qualifications and to write a flag in the flag storage location associated with each of the stored words of data if the stored words of data do not meet the pre-established qualifications, so that edited data words meeting the pre-established qualifications can subsequently be recognized by the absence of a flag in their associated flag storage locations, both the edited and unedited data being retained in said first storage means after editing for selected use including verification and evaluation of the operation of said automatic editing means.
