Flow display type indicating method and apparatus
First Claim
1. A method of indicating a value of a predetermined physical quantity in a form of flow representation, said value having a polarity and a magnitude, said method comprising the steps of:
- defining a flow representing image for representing a flow;
indicating the polarity of said value by at least one direction of flow of said flow representing image along a predetermined line; and
indicating the magnitude of said value by a speed of flow of said flow representing image.

Abstract
A flow display type indicator is provided which indicates the variation or the velocity of variation of the value of a physical quantity or a parameter in a readily identifiable form. The indicator includes a flow image forming unit to indicate the value of the predetermined physical quantity in a flow representation by enabling a flow representing image to be formed at one of a plurality of positions including first to n-th positions which are orderly disposed and offset from each other along a predetermined line. A flow image selector selects one from flow representing images at the first to the n-th positions in one of first and second directions depending on the polarity of an input signal at a speed in accordance with the magnitude of the input signal to allow the flow representing image forming unit to form a selected flow representing image.

14. A flow display type indicator for indicating a value of a predetermined physical quantity, comprising:
-
an input terminal for receiving an input signal representative of a value of said predetermined physical quantity; flow representing image forming means for forming a flow representing image at an n number of different positions along a predetermined line, said n positions comprising first to n-th positions orderly disposed and being offset from each other, said first position defining a next position to said n-th position in a first direction, said n-th position defining a next position to said first position in a second direction opposite to said first direction; and flow representing image selecting means connected to said flow representing image forming means, for selecting said flow representing images at said first to n-th positions in one of said first and second directions depending on a polarity of a first signal received from said input terminal and at a speed in accordance with a magnitude of said first signal, in order to cause said flow representing image forming means to form the selected flow representing image. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
