Abstract: An electro-mechanical display including a rotating focusing device and at least one light source. The position of the focusing device is monitored and the light source turned on under computer control to produce at a viewing position a plurality of light indications from a single source.

Abstract: An electronic toy doll including electronic control circuitry responds to selection of one of a plurality of switches on the doll housing and selects associated vocal messages. The control circuitry includes a stored program of instructions and also permits a problem-solution mode of operation where the user is given a message selected by a weighted probability of the occurrence of a problem and then the doll responds according to how the user correctly or incorrectly responds to the various switch response operations possible.

Abstract: An electronic guessing game is disclosed which includes a keyboard for entering numbers, and a light and speaker for producing a variety of visual and audible signals. A prize is also provided within a transparent housing. A first player enters a secret number by means of the keyboard. A second player then enters his guess at the secret number using the same keyboard. The second player attempts to retrieve the prize by reaching into the transparent housing. The position of the players hand is detected by a group of photocells. If the player's guess is not equal to the secret number, the game will generate an error signal and the player must withdraw his hand. The closer the player's guess is to the secret number the closer he may approach the prize before the error signal is sounded. If the player guesses the secret number within a preallotted time interval, he may retrieve the prize. A mode of operation is also disclosed in which the game chooses the secret number by means of a random number generator.

Abstract: A hand held electronic game for baseball or the like having a playing field with illuminatable segments thereon at positions generally corresponding to potential player positions. One group of segments defines the path of a player object such as a ball which when "impacted" in response to a correctly timed manual input illuminates one of another group of segments. The "player" is advanced in response to another manual input a distance determined by the segment so illuminated. Game control and game status is under control of a processor using probabilities to determine game events. In the embodiment illustrated, the game is in the form of a baseball game with the segment depicted on a baseball diamond.

Abstract: A novel game is disclosed featuring a playing field having at least three lanes and divided into at least six rungs.
