International Classification:

G09F 2700

US Classification:

40455

Abstract:

An activated work comprising at least two turnable pages pivotably attached to one edge of each of the pages so that the pages are pivotable from a juxtaposed closed position to an adjacent opened position, a visual image display affixed to one of the pages, the visual image display having a first visual activation state at which a visual image is not visible thereon and a second visual activation state at which a visual image is visible thereon, a sound generator attached to the work having a first activation state at which an audible sound is not generated and a second activation state at which an audible sound is generated, connected to the visual display for selectively activating the visual display from one of the visual activation states to another upon pivoting the pages from the open position to the closed position, and connected to the sound generator for selectively activating the sound generator from one of the sound activation states to another upon pivoting the pages from the closed position to the opened position or from the opened position to the closed position.

Filed:

Sep 25, 1980

Appl. No.:

6/190612

Inventors:

Alfred E. Hall - Dallas TX

Assignee:

Sigalos & Levine, P.C. - Dallas TX

International Classification:

A63F 906

US Classification:

273153R

Abstract:

An electronic logic game method and apparatus comprising a device for simulating a balance scale in its balanced state or either of its unbalanced states, a device for simulating playing pieces one of which is simulated to be heavier or lighter than the others and selected ones of which may be symbolically placed on said simulated balance scale, and a device coupled to said simulated balance scale for detecting the presence or absence of the simulated heavier or lighter playing piece and simulating the scale to be balanced or unbalanced in a predetermined direction according to the presence or absence of the piece whereby the heavier or lighter piece may be logically discovered in a predetermined number of electronic scale balance or unbalance representations.

International Classification:

A63F 906

US Classification:

273153R

Abstract:

An electronic logic game comprising a device for simulating a balance scale in its balanced state or either of its unbalanced states, a plurality of simulated playing pieces one of which is simulated to be heavier or lighter than the others and selected ones of which may be symbolically placed on said simulated balance scale, and a device coupled to said simulated balance scale for detecting the presence or absence of the simulated heavier or lighter playing piece and simulating the scale to be balanced or unbalanced in a predetermined direction according to the presence or absence of the piece whereby the heavier or lighter piece may be logically discovered in a predetermined number of electronic scale balance or unbalance representations.

US Patent:

58203796, Oct 13, 1998

Filed:

Apr 14, 1997

Appl. No.:

8/837131

Inventors:

Alfred E. Hall - Dallas TX
B. Grady Smith - Dallas TX

International Classification:

G09B 500

US Classification:

434178

Abstract:

A method of displaying a self-reading electronic child's book on a display medium that displays a sequence of indicia, such as words, and having associated with the first indicia or word a visual indicator that may be associated with a cursor moved by a child to audibilize the indicia or word associated with the visual indicator and automatically cause the visual indicator to move under the next indicia or word in sequence to enable a book to be read by a child.
