摘要:
Computer-implemented method for assessing an aging adult's ability to classify formant transition and segment duration information in making phonetic categorizations. A representative subset of multiple confusable pairs of phonemes is selected. A representative subset of multiple stimulus levels for the phonemes is selected for use with the phoneme subset. For each pair of phonemes of the phoneme subset, at each stimulus level of the stimulus level subset: icons for each phoneme are graphically presented, and a computer-generated phoneme from the pair is aurally presenting at the stimulus level. The adult is required to select one of the icons corresponding to the aurally presented phoneme, and the selection's correctness or incorrectness recorded as a response result. A success rate is determined based on the response results, the success rate comprising an estimate of the adult's success rate with respect to the multiple confusable pairs of phonemes at the multiple stimulus levels.
摘要:
A method on a computing device for enhancing the memory and cognitive ability of an older adult by requiring the adult to differentiate between rapidly presented stimuli. The method utilizes a sequence of phonemes from a confusable pair which are systematically manipulated to make discrimination between the phonemes less difficult or more difficult based on the success of the adult, such as processing the consonant and vowel portions of the phonemes by emphasizing the portions, stretching the portions, and/or separating the consonant and vowel portions by time intervals. As the adult improves in auditory processing, the discriminations are made progressively more difficult by reducing the amount of processing to that of normal speech. Introductory phonemes may each include a blend of a formant-synthesized phoneme and an acoustically naturalistic phoneme that substantially replicates the spectro-temporal aspects of a naturally produced phoneme, with the blends progressing from substantially natural-sounding to substantially formant-synthesized.

摘要:
A method on a computing device for enhancing the memory and cognitive ability of a participant by requiring the participant to differentiate between rapidly presented aural stimuli. The method trains the time order judgment of the participant by iteratively presenting sequences of upward and downward formant frequency sweeps, in random order, separated by an inter-stimulus interval (ISI). The upward and downward formant frequency sweeps utilize frequencies common in formants, i.e., the characteristic frequency components common in human speech. Icons are associated with the upward and downward formant frequency sweeps to allow the participant to indicate an order in which the sweeps are presented (i.e., UP-UP, UP-DOWN, DOWN-UP, and DOWN-DOWN). Correct/incorrect selection of an order causes the ISI and/or the duration of the frequency sweeps to be adaptively shortened/lengthened. A maximum likelihood procedure may be used to dynamically modify the stimulus presentation, and/or, to assess the participant's performance in the exercise.

The invention relates to a method for producing electronic components consisting in carrying out a first anodisation of a carrier material (1) for forming at least one first pore (3) extending in a first direction in said carrier material (1) and in carrying out a second anodisation for forming at least one second pore (17) extending in the carrier material (1) in a second direction different from the first direction

A buffer layer is employed to fabricate diamond membranes and allow reuse of diamond substrates. In this approach, diamond membranes are fabricated on the buffer layer, which in turn is disposed on a diamond substrate that is lattice-matched to the diamond membrane. The weak bonding between the buffer layer and the diamond substrate allows ready release of the fabricated diamond membrane. The released diamond membrane is transferred to another substrate to fabricate diamond devices, while the diamond substrate is reused for another fabrication.

The present invention relates to a catcher's chair useful for a person to assist a baseball or softball pitcher practicing throwing a ball to a catcher. The catcher's chair is at a height which allows the user to sit at the catcher's normal catching position, reducing strain on knees and legs. The catcher's chair comprises a horizontally placed seat, a front panel functioning as a leg to place the catcher's chair at a distance above the ground and also extending above the level of the seat to protect the groin of the catcher when straddling the catcher's chair and facing toward the front panel. A rear panel attached to the opposite end of the seat forms the second leg of the catcher's chair. Optionally a support panel may be attached to the front and back panels under the catcher's chair to provide stability. A kit may be provided containing unassembled parts which can then be assembled to form the catcher's chair.
