Methods and apparatus for an improved control parameter value indicator
First Claim
1. A control value indicator for indicating whether a control value is set within a predetermined tolerance of a set-point value marked by a set-point marker on a scale having a pointer, said control value indicator being in the form of one of said set-point marker and said pointer and having a first graphical configuration corresponding to the case where said control value is not within said predetermined tolerance of said set-point value, and a second graphical configuration corresponding to the case where said control value is within said predetermined tolerance of said set-point value.

Abstract
Accurate, unambiguous, and space-efficient electronic display techniques are provided for presenting the operator with an indicator whose graphical configuration varies in accordance with whether the relevant control value is within a predetermined tolerance range of a set-point value. More particularly, a control value indicator includes a scale having an axis associated with the control value, a set-point marker placed at a first position along the scale for indicating the set-point value, and a pointer having a second position along the scale for indicating the control value. The pointer and/or the set-point marker exhibit a first graphical configuration corresponding to the case where the control value is not within the predetermined tolerance of the set-point value, and a second graphical configuration corresponding to the case where the control value is within the predetermined tolerance of the set-point value.

4. An electronic display system for providing visual feedback to an operator, said system comprising:
-
a display for displaying a control value indicator, in the form of one of a set-point marker and a pointer, viewable by said operator; a control input for receiving manual input from said operator; a controlled subsystem for receiving an input from said control input and producing an output; a processor having memory means associated therewith for storing a set-point value, marked by said set-point marker on a scale having said pointer, and tolerance information, said processor further configured to receive a control value based upon a parameter of said controlled subsystem, compare said control value to said set-point value and said tolerance information, and to communicate with said display to display said control value indicator; said control value indicator having at least two graphical configurations based on said control value, said set-point value, and said tolerance information.
