Scale and indicator correlation for an adjustment dial
First Claim
1. A scale and indicator correlation mechanism for an adjustment dial, comprising:
- a bistable display substrate, having a display surface divided into a plurality of sectors, the display surface being configured to display a plurality of characters arranged in a pattern with consecutive ones of the plurality of characters displayed in consecutive ones of the plurality of sectors, the characters representing parameter values for controlling local equipment;
a dial for an adjustment dial, the dial, superimposed on the bistable display substrate, the dial having an indicator being configured to be manually aligned with a selected one of the plurality of characters being displayed in a selected one of the plurality of sectors of the bistable display substrate, the selected one of the plurality of characters representing a manual setting of a parameter value for controlling the local equipment;
a position detector, coupled to the dial, outputting a position signal representing a current position of the indicator of the dial, the current position being the selected one of the plurality of sectors of the bistable display substrate with which the indicator of the dial is aligned;
a network interface connected over a communications network to a remote human-machine interface, being configured to receive from the remote human-machine interface, a new parameter value for controlling the local equipment; and
a controller coupled to the bistable display substrate, to the position detector, to the network interface, and to the local equipment, the controller being configured to sample the current position of the indicator of the dial, and in response, to provide the control input signal to the bistable display substrate to control a display of the new parameter value in the current position of the indicator of the dial and to provide the new parameter value to the local equipment.

Abstract
The invention provides consistent settings between local and remote parameter adjustments of both local and remote HMI. A dial (4) is superimposed on a bistable display substrate (2), having an indicator (7) configured to be manually aligned with a displayed character representing a manual setting of a parameter value for controlling local equipment. A network interface (18) is connected over a communications network (17) to a remote HMI (16), configured to receive a new parameter value for controlling the local equipment (25). A controller (14) samples the current position of the indicator (7) of the dial (4), and provides a control input signal (20) to the bistable display substrate (2) to control a display of the new parameter value in the current position of the indicator (7) of the dial (4) and to provide the new parameter value to the local equipment (25).

13. A method, comprising:
-
displaying a plurality of characters on a bistable display substrate, the characters arranged in a pattern with consecutive ones of the plurality of characters displayed in consecutive ones of a plurality of sectors, the characters representing parameter values for controlling local equipment; aligning an indicator of a dial with a selected one of the plurality of characters being displayed in a selected one of the plurality of sectors of the bistable display substrate, the selected one of the plurality of characters representing a manual setting of a parameter value for controlling the local equipment; detecting a current position of the indicator of the dial, the current position being the selected one of the plurality of sectors of the bistable display substrate with which the indicator of the dial is aligned; receiving from a remote human-machine interface, a new parameter value for controlling the local equipment; and displaying on the bistable display substrate, the new parameter value in the current position of the indicator of the dial and providing the new parameter value to the local equipment. - View Dependent Claims (14, 15)
