Quantitative display apparatus
First Claim
1. A display apparatus comprising:
- a frame defining a central region;
at least one set of indications arranged on said frame around said central region;
at least one projection arranged proximate, in correspondence with or in alignment with one of said at least one set of indications; and
a rotation mechanism coupled to a connection point on each of said at least one projection to rotate said projection such that said connection point is rotated in a loop around said central region, said rotation mechanism being arranged to determine a quantity to be displayed and control rotation of said at least one projection based thereon.

Abstract
Display apparatus including an annular frame defining a central region, at least one set of indications arranged on the frame around the central region, at least one projection arranged proximate, in correspondence with or in alignment with one set of indications, and a rotation mechanism coupled to a connection point on each projection to rotate the projection such that the connection point is rotated in a loop around the central region. The rotation mechanism determines a quantity to be displayed and control rotation of the projection(s) based thereon. The projections can extend inward from rotatable rings (and not outward from a common, central point or area) so that the central region defined by the frame may be open. When multiple rings are used in connection with the same set of indications, the projections on the rings are different in form, size, color and/or shape.

19. A display apparatus comprising:
-
a frame defining an interior space;
a screen arranged in said interior space; and
measuring and display means arranged in connection with said frame and coupled to said screen for determining at least one physical quantity to be displayed on said screen and directing said screen to display a set of indications in a fixed position relating to said at least one physical quantity and at least one projection arranged to move relative to said indications, said measuring and display means being arranged to cause said at least one projection to move relative to said indications as at least one physical quantity changes. - View Dependent Claims (20)
