A device for balance training and assessing dynamic balance by measuring a subject's ability to react to perturbations. A universal joint assembly is translated at the base of a support plate while a top plate on which the subject stands is fixed against translation. The universal joint permits the attached top plate to rotate about at least one and preferably multiple axes, and the subject must control balance following the translation of the universal joint. All components are housed in a one-piece platform assembly, made up of two plates in which the components are mounted. An existing force plate measurement system is placed on the top plate, and the subject stands thereon during use. A virtual environment, by image-creating devices, may be used to create a realistic sensation of tripping and general postural instability, or shifting of the support surface.

A system and method for use in moderating symptoms associated with vestibular disorders. The user stands atop a balance platform and balances or performs other exercises on the platform. The exercises require the user to work against the instability of the platform. Training difficulty may be increased or decreased by changing the pressure of the platform. Over time, the repeated performance of the exercise sessions improves the impairment the user is experiencing due to the symptoms of the vestibular disorder.

A balance trainer has a board with a notional nose and tail, a rolling fulcrum for the board to perch on, and at least one hold-down link extending between one end anchored to ground and another end secured to the notional tail of the board. The board as perched on the rolling fulcrum would—in the absence constraint—afford free tipping tilt along at least one axis. However, the hold-down link supplies constraint such that free leash is given to the to the notional tail of the board so long as the hold-down link is slack. But when the nose of the board dives furthest against the hold-down link, the board either deadens in a fixed pitch angle against the tautened hold-down link, or else can be swung laterally a bit, in sort of a monkey-swing fashion in inverse, giving a training experience like riding on a long surf board.

A board for balance training has an upper footstep surface, lower bearing surface and a progressive series of concentric, cylindrical sub-frames depending from the lower surface which enclose progressively smaller framed-in areas of the bearing surface within progressively smaller framed-in crown-cavities defined by each. This progressive series ranges extremes of a major in size to minor, with none, one or more intermediates. All at least but the major sub-frame are selectively removable from the board for clearing way for progressively larger framed-in crown-cavities. Any of the sub-frames permit a training ball to roll freely sandwiched between the board and ground unless stopped against any portion of that sub-frame. Selectively utilizing a minor sub-frame over, conversely, exclusion thereof in favor of any of the progressively larger sub-frames, progressively changes the level of difficulty for trainees standing on the upper footstep surface.

The invention discloses a hard disk failure prediction method for a cloud computing platform. The hard disk failure predication method comprises the following steps: marking SMART log data of a hard disk as a normal hard disk sample and a faulted hard disk sample according to a hard disk maintenance record in a prediction time window; then, dividing the denoised normal hard disk sample into k non-intersected subsets by adopting a K-means clustering algorithm; combining the k non-intersected subsets with the faulted hard disk sample respectively; generating k groups of balance training sets according to an SMOTE (Synthetic Minority Oversampling Technique) so as to obtain k support vector machine classifiers for predicting the faulted hard disk. In the prediction stage, test sets can be clustered by using a DBSCAN (Density-based Spatial Clustering Of Applications With Noise), a sample in a clustered cluster is predicted as the normal hard disk sample, a noise sample is predicted by each classifier obtained by training, and further a final prediction result is obtained by voting. According to the method disclosed by the invention, hard disk fault prediction is carried out by using the SMART data of the hard disk, and relatively high fault recall ratio and overall performance can be obtained.

A text classification method comprises following steps: dividing the initial training text collection into a plurality of subsets including the text in the same category based on the category, extracting the corresponding probability topic model from each subset; generating new text to balance the categories of the subsets by the corresponding probability topic model; constructing a classifier based on the balance training text collection corresponding to plural subsets; and processing text classification by the classifier. The invention can improve the classification effect of the text classification method under the condition of data skew.

A novel balance exercise apparatus and method of training is disclosed which includes a spanning system which spans between two positions in space and supports a suspended system which is suspended between the two positions in space. A user trains their balance skills and exercises by positioning all or part of their body on the suspended system and then moves their body to maintain their balance while remaining in place or doing exercises. The suspended system creates a dynamic balance environment where the suspended system may move such as swing, bend, rotate, or twist, all controlled by the balance and movement of the user. The suspended system may consist of rigid and / or flexible devices that are supported by the spanning system above the ground. In addition, the spanning system and the suspended system may include devices to vary the nature and difficulty of the dynamic balance environment. The dynamic balance environment may range from stiff to very soft and incorporate variable spring and bounce properties. The dynamic nature of the balance environment makes this system a very effective and challenging balance training system.
