Abstract: A portable tooth-sensitivity demonstration apparatus and a process. The apparatus includes a main unit with a top cover having at least one tooth station thereon; an electrical circuit, a sensitivity indicator, and an on/off switch. A sensor in the tooth station is part of the electrical circuit to activate a response by the sensitivity indicator. A water-permeable tooth piece, treated with an oral-care product, is placed into the tooth station, and a few drops of water are deposited on top of the tooth piece. Lack of response from the sensitivity indicator shows an absence of sensitivity and hence effectiveness of the oral-care product, while a response from the sensitivity indicator shows existing sensitivity and thus failure of the oral-care product to seal the tooth piece. In an apparatus having multiple tooth stations, different oral-care products can be assessed simultaneously and side-by-side.

Abstract: The invention provides a computer-implemented method for analyzing a piece of text. The method comprises truncating one or more characters of the text into one or more block units each having at least one character. The method includes sorting the one or more block units for one or more unique block units and comparing the one or more unique block units with a grading database to thereby assign a grade to each of the one or more unique block units. An overall grade for the piece of text may be determined based on one or more of the grades assigned to each of the one or more unique block units. The overall grade of the text may be derived from successive truncating of the text into block units of increasing size and the successive processing of such block units.

Abstract: A learning sub-system models search patterns of multiple experts in analyzing an image using a recurrent neural network (RNN) architecture, creates a knowledge base that models expert knowledge. A teaching sub-system teaches the search pattern captured by the RNN model and presents to a learning user the information for analyzing an image. The teaching sub-system determines the teaching image sequence based on a difficulty level identified using image features, audio cues, expert confidence and time taken by experts. An evaluation sub-system measures the learning user's performance in terms of search strategy that is evaluated against the RNN model and provides feedback on overall sequence followed by the learning user and time spent by the learning user on each region in the image.

Abstract: An optimization engine builds a set of test forms, called a pallet for use in a qualification test setting. The pallet is generated using a optimization engine programmed with constraints and goals for each test form in the pallet and for the pallet in general. A test information floor is set at the cut point of the test which causes test items to be focused at the area of the test where the pass/fail decision is made. Further constraints may be programmed to maximize the item diversity, that is, to spread the use of available test items as uniformly as possible.
