Abstract: A computer-aided-educational system and method for rewarding a student when the student attains a milestone in a subject. The subject is divided into line-items with at least one line-item being more difficult than another line-item. In one embodiment, the system includes a milestone setter, a performance analyzer, a reward determinator and a reward generator. The milestone setter sets a number of milestones, with each milestone being related to a line-item, and with an instructor providing inputs to the milestone setter to set each line-item that has a milestone to be reached. In one embodiment, at least one such line-item reflects the student's understanding in the subject. The performance analyzer coupled to the milestone setter determines whether the student has reached a milestone. The reward determinator coupled to the performance analyzer determines a reward for the student if the performance analyzer indicates that the student has reached a milestone. The reward can depend on the student's preference.

Abstract: An electronic sound and music making device includes a memory that stores a plurality of sound segments, such as musical notes, animal noises, etc., a keypad having a series of keys, each of each indicates and is associated with a different one of the stored sound segments, and a set of visual indications, such as light emitting diodes (LEDs), that indicate when different ones of the sound segments are being played. The device repeats a programmable sequence of, for example, four of the stored sound segments to form a song while, simultaneously turning on different ones of the LEDs to indicate the different sound segments being played. The keypad enables a user to specify the identity and the order of the sound segments to be played and allows a user to substitute any of the sound segments stored in the memory with the sound segments being played so as to produce a new or different song.

Abstract: A weapons training range provides a simulated weapons use scenario including return fire. A microprocessor selects branches from a multi-branch program and causes an image projector to project subscenarios on a display screen visible to a participant. In response to the subscenarios, the participant fires at projected threats. Return fire simulators positioned behind the display screen return fire toward the participant. Obstructions are placed in the weapons range to provide cover for the participant. A video camera and X-Y position sensor identify the X-Y location of the participant and try to detect exposed portions of the participant. Based upon the identified X-Y location and any detected exposed portions, the microprocessor aims the return fire simulators to provide simulated return fire. To simulate real world aiming, the microprocessor induces time-based and response-based aiming errors.

Abstract: A computer-aided-educational system and method to further a student's understanding in a subject through associating the subject's different areas that the student has learnt. The subject is divided into line-items and relationship-items, with each relationship-item relating two or more items. The items are separated into learnt and un-learnt elements. The invention includes the steps of (1) selecting an un-learnt element; (2) generating learning materials for the student to learn the selected element; and (3) assessing the student's learning progress in the selected element. If the assessment on the selected element is satisfactory, then the invention (1) classifies one or more relationship-items to be learnt as un-learnt elements, with each classified relationship-item relating the selected element with one or more learnt elements; and (2) re-classifies the selected element as a learnt-element. Then the invention repeats from the step of selecting an un-learnt element.

Abstract: A manually operable device for holding and rotating candy, such as a sucker, that requires only one hand to hold and operate. The device has a handle portion that may be held with one hand of the user. A trigger is carried by the handle for manipulation against the bias of a spring or the like using the same hand of the user as is holding the handle. Actuation of the trigger moves a rack which in turn both rotates and linearly moves a set of gears to rotate a shaft that extends out of the handle. Attached to the end of the shaft extending out of the handle is a sucker or lollipop that is rotated as a result of actuation of the trigger. The sucker may be carried on a dish which is attached to the shaft, outside of the handle portion, for rotation with the shaft.

Abstract: The invention uses dice-like polyhedral solids (30) (32) (44) to generate randomly the lines of I Ching hexagrams. It produces outcomes according to a traditional and theoretically important frequency distribution. That distribution requires that the four line types of the I Ching system (36) (42) (38) (40) occur in a relative frequency of 1:3:5:7. The invention accomplishes this through a specific arrangement of indicia (26) (28) (46) (48) (50) on the dice. The dice are so constructed and the indicia so disposed that any roll shall yield one of the numerical results 6, 7, 8, or 9. These values correlate with the four line types, and the statistical likelihood of each possible result conforms to the theoretically ideal frequency distribution of all such results. Three dice are used in the preferred embodiment, each of a rounded, substantially tetrahedral form.

Abstract: A game for teaching reading skills through phonics and decoding skills. The game provides for increasing student (player) interest by incorporating a wagering system similar to that of casino Blackjack. The wagering aspect makes the game attractive to mature students (players) who are learning to read or are improving their reading skills. The game uses word cards and sentence cards. The word cards have specially-selected words to emphasize important vowel sounds, common two letter combinations (consonant--consonant and consonant-vowel) and are selected to use words falling into categories selected for their universal association. The sentence cards are a logical progression from the philosophy of Universal Associative Learning, and pose questions or assign tasks to emphasize reading comprehension and critical thinking skills. The game also uses timing means which sets a period of time in which the card must be correctly responded to, and also uses chips for the placing of wagers.
