Abstract: An improved verbally interactive telephone interrogation system is provided in which a two-way telephone subscriber network, such as a Touch-Tone type two-way telephone subscriber network, is utilized to enable both telephone call placement and individualized remote variable audio message selection and interrogation of prerecorded audio messages as well as remote response accumulation. The Touch-Tone type telephone, which is employed to maintain normal telephone contact with other subscribers, is also utilized to call-up a multitrack magnetic storage device which provides selectible reproducible conversational responsive audio messages to particular primary reproducible interrogatory message from a plurality of different selectible audio messages stored thereon.

Abstract: A handheld electronic learning aid is disclosed. The learning aid is utilized for teaching and testing associations between pictorial representations and the correct responses to the pictorial representations. A selected one of an associated group of numbered printed pictorial representations is randomly selected by the learning aid, and the operator attempts to correctly respond to the pictured object. Scoring functions and displayed reward phrases provide positive reinforcement of learned skills. One embodiment of the learning aid is utilized to teach and strengthen spelling skills in young children. Additionally, anagram or other alphabetic type modes of operation can provide training and experience in literary skills.

Abstract: An electronic question-and-answer device includes a keyboard on which codes associated with questions and answers may be entered. The device also includes indicator lights and a sound-generating device for indicating whether the correct answer has been entered on the keyboard. Circuitry is included that interprets the question code and answer code as numerical values and compares the numerical values entered thereby. In order that different correspondences between question codes and answer codes can be used with different sets of questions and answers, each set of questions and answers is provided with a different key-defining connector that connects the keyboard and internal circuitry in such a manner as to define the number entered by a given key.

Abstract: A game mechanism including first and second electrically operated alarms and first and second switches for activating the same. A container for the object and a display of the symbolic equipment of the object in the container are also included. A third switch selectively activates a first or second switch in conjunction with the equivalence of the object in the container and the display of the symbolic equivalent of the same such that activation of the first and second switch occurs to reinforce a right or wrong answer as to the identity of the object by the user.

Abstract: Apparatus for converting a train of code signals representative of a letter, number, or symbol to a visual display of such corresponding letter, number, or symbol. The train of signals includes individual signals of at least two distinct time durations, the length of the time durations being dependent upon the proficiency of the operator initiating the signals. In the signal converting apparatus, a clock signal of a preselected time duration is produced. The time relation of each of the signals in the train of signals is resolved in relation to the clock signal. A first signal is produced if the signal being resolved is less than the clock signal, and a second signal is produced if the signal being resolved is greater than the clock signal. An addressor receives the first and second signals and stores the signals to generate a given address dependent upon the particular first and second signals and the order those signals are received. The addressor produces a signal indicative of the given address.
