Abstract: The present disclosure relates to a system and a method for determining a perceptual-cognitive signature of a subject. A plurality of objects moves at a controlled speed on a visual display, for a predetermined duration in each of a series of core trials. The subject identifies one or more target objects amongst the plurality of objects. The perceptual-cognitive signature of the subject is determined according to the number of target objects, the speed of the objects, the predetermined duration of each of the series of core trials, and a correctness of identifications, by the subject after each predetermined duration, of the target objects over the series of core trials.

Abstract: The present disclosure relates to a perceptual-cognitive-motor learning system. The system includes an apparatus for evaluating or improving perceptual-cognitive abilities of a subject during a training sequence. The system also has a training sequence controller for adding in at least a part of the training sequence at least one of (a) a first motor load add-on to the subject and (b) a second motor load add-on to the subject, the second motor load being heavier than the first motor load. A variant of the system has a user interface for allowing the subject to change at least one parameter of the training sequence. Methods for evaluating or improving perceptual-cognitive abilities of a subject are also disclosed.

Abstract: The present disclosure relates to a perceptual-cognitive-motor learning system. The system includes an apparatus for evaluating or improving perceptual-cognitive abilities of a subject during a training sequence. The apparatus includes a display configured to provide to the subject a visual contact with an environment. The system also has a training sequence controller configured to consolidate results of first successive tests made using a single spatial zone formed by the environment, segment the into a plurality of spatial zones, and consolidate results of second successive tests made using the plurality of spatial zones. Methods for evaluating or improving perceptual-cognitive abilities of a subject are also disclosed.

Abstract: The invention relates to an improved dental tool drive arrangement for a handpiece with a drive head, the tool drive arrangement permitting length adjustment of the tool in the drive head by concentrically supporting the tool in the drive head at any position from a fully inserted position to a maximum retracted position. The tool drive arrangement preferably includes a tool and a rotatable tool supporting element for concentrically supporting the tool from the fully inserted to the maximum retracted position, the tool preferably including a maximum retraction indicator for indicating to a user when the tool has been retracted to the maximum retraction position. This provides a significant advantage over the prior art by allowing a user to adjust the exposed length of a rotatable tool, preferably a dental bur, without exceeding safe operating limits.
