rai Training method and a device for carrying out said method By www.freepatentsonline.com Published On :: Tue, 19 May 2015 08:00:00 EDT The invention relates to training and can be used for learning and/or developing movement skills, fixing dynamic stereotypes and for training movement coordination. The aim of the invention is to provide a trainee with on-line correcting tactile feedback during training and to improve techniques and rate of a movement by bringing it as close as possible to a reference movement. The inventive training method consists, when learning a movement, in digitizing said movement, in comparing it with the digitized pattern of a reference movement and, if the trainee deviates from the reference movement, in receiving by said trainee a tactile feedback (tactile action) for on-line correcting said movement. The inventive device comprises sensors for on-line movement digitizing, a computer for comparing the thus obtained digitized movement with the reference movement (specified by an expert or simulated on the computer) for controlling the tactile feedback elements and said tactile feedback elements for performing the correction action.

rai Team-building educational training system By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT The team-building educational training system includes a mat and a plurality of reflective surfaces, such as mirrors. The mat has a top surface, a bottom surface, and a plurality of openings defined therein. The top and bottom surfaces each have a plurality of uniquely identifiable indicia displayed thereon. The reflective surfaces are placed on the floor or ground under the mat. The team cooperatively lifts and manipulates the mat to align the openings with the reflective surfaces so that at least one team member can view reflections of the indicia on the reflective surfaces. The team cooperatively interprets the indicia and completes a variety of planned exercises to learn skills for working as a team. Full Article
rai System and device for welding training By www.freepatentsonline.com Published On :: Tue, 11 Aug 2015 08:00:00 EDT A system and device for welding training. In one example, a welding training system includes a display configured to show welding features related to a training welding operation. The system also includes a training workpiece having a substantially transparent weld joint configured to be placed adjacent to the display during the training welding operation. The system includes a processing device coupled to the display and configured to provide welding data relating to the training welding operation to the display. The system also includes a training torch comprising an optical sensor. The training torch is coupled to the processing device and configured to provide the processing device with data from the optical sensor corresponding to a position of the training torch relative to the training workpiece.
