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.

More specifically, the rehabilitation system includes at least one two degree-of-freedom robotic, haptic interface for a mammalian foot and interactive gaming hardware that is coupled to a controller, to provide a virtual reality-like environment.

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.

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.

The joint includes all of knee joint, ankle joint and hip joint of the lower limb, and the movement of important muscles of the lower limb can be detected. With the apparatus attached, the patient can perform a balance training of alternatively raising the paralyzed lower limb and the normal limb, a standing training of bending and straightening both knees of the lower limbs and a walking training of using the both lower limbs.

A resistance exercise machine having cable and pulley linkage assemblies attached to a single weight stack or other resistance means. Each cable and pulley linkage assembly, which is independent of the other(s), can be used by one arm or leg during bilateral exercise training (that is, training in which both limbs of a pair are used to simultaneously to lift a weight or work against various resistance means). A biofeedback assembly measures and displays in real-time how much each limb of a pair is contributing to such effort.

An exemplary exercise device includes a deck, a track, and a ball. Opposing ends of the deck include foot supports. The track bulges upwardly from the deck to form a dome that receives the ball. With the ball and deck on the floor, a user balances herself on the foot supports and may move along multiple axes as the ball rolls on the floor. The user may (for example) pivot and rock the exercise device (as she balances herself), rolling the ball along the track while alternately touching the ends of the deck to the floor, or the user may twist the exercise device clockwise and / or counterclockwise. The exercise device allows for enhanced strength and cardiac training, in addition to balance training, as the user engages in motions and repetitions that may include rolling the ball in the track and contacting different portions of the deck with the floor.
