Abstract: EEG-based acceleration of second language learning is accomplished by measuring via single-trial EEG a learner's cognitive response to the presentation (visual or auditory) of language learning materials and updating a user model of latent traits related to language-learning skills in accordance with the cognitive response. The user model is suitably updated with each trial, each trial being triggered by learner fixation on a portion of visual materials and/or a next phoneme in auditory materials. Additional discrimination may be achieved through the use of saccades or fixation duration features.

Abstract: The present invention is directed to methods and devices for teaching the proper configuration of the oral articulators, particularly the tongue, corresponding to particular speech sounds by providing intraoral tactile feedback. Intraoral tactile feedback is achieved by placing nodes in the oral cavity of the patient in locations corresponding to the proper lingual position required to produce a target sound. These nodes facilitate identification of the appropriate lingual position corresponding to a target speech sound by providing tactile differentiation when the target sound is properly produced.

Abstract: A refreshable tactile reader apparatus for Braille text and graphics, utilizing a plurality of compressible tactile pins that can absorb strong downward forces. Such strong forces transmitted through tactile pins can damage pin actuation mechanisms. The physical enclosure of the reader provides open channels that allow the apparatus to be more easily cleaned than prior art enablements.

The method involves building an active foreign language alphabet and language as it is done naturally in user's native language. The learning aid further includes an interactive-based, task-oriented system integrated into software for upload onto a computer.

Abstract: A medical training and simulation system includes a plurality of inanimate objects, each being associated with an identification tag which stores an identification code which uniquely identifies an associated object. A database stores information of the objects. A reader reads a respective identification code of a selected object. An information retrieving processor retrieves the stored information which corresponds to the read identification code of the selected object. A device reproduces at least a portion of the retrieved information of the selected object.

Abstract: Interactive electronic training systems and methods are described herein. Certain embodiments provide preprogrammed video, audio, and/or textual presentations of training materials which provide information related to skills/information to be trained. A scenario including real or animated actors is presented, simulating an interaction. The training system presents related queries for the trainee who audibly responds. The training system stores a score based in part on a comparison of the trainee's response with an answer stored in training system memory. Optionally, the scores are substantially immediately presented by the system to the trainee.

Abstract: A system and method is disclosed for providing differentiated content to a user comprising determining a skill level of the user, obtaining unmodified content, aligning the unmodified content to a set of content standards, modifying the aligned content in accordance with the user's skill level, providing the modified aligned content to the user, re-assessing the user's skill level based on a response from the user to the modified aligned content, and modifying new aligned content in accordance with the re-assessed user's skill level.

Abstract: A taxidermic method for game-head mounting. A retainer is provided for keeping an ear supported by an ear liner properly posed on a mannikin while the game-head is drying. The retainer has an upwardly extending substantially straight stem portion having an upper end portion downwardly bent into a substantially straight right angle arm. The arm has a lower end portion bent upwardly into a U-shaped hook portion for holding a rim of the ear supported by the ear liner during drying of a cape on the mannikin.

Abstract: A method and apparatus for simulating a missile. A simulation program for a weapon using a processor unit is executed in a simulation unit. A number of input signals is received from a control station in a vehicle through an interface system connected to a weapons interface on the vehicle.

A number of output signals is generated using a simulation of the weapon. The number of output signals is sent through the weapons interface to the control station.

Abstract: An improved method of teaching mathematics which enables students to take an active and enjoyable role in their own learning via an interactive puzzle is disclosed. In the preferred embodiment, each of the ten digits, zero through nine, is “hidden” within one of ten value positions (52). Students must deduce the value of each position by forming sums, differences, products, and/or quotients of the positions. Freedom of selection of positions and operations provides for individualized approaches to puzzle solutions, and the interplay of values and operations promotes number sense. Mathematical reasoning is intrinsic to the puzzle. Programmable settings (72) allow the teacher to modify the puzzle, including substituting more challenging values in place of the digits (98), supplying more complex functions (106) in place of the four elementary arithmetic operations, and adjusting the format of the answers.
