Abstract: A core strengthening assembly for performing core strengthening exercises includes a ball that may be positioned on a support surface. A harness is positioned around the ball and the ball rotates freely in the harness. A pair of pedals is each removably coupled to the harness. Each of the pedals may have one of a user's feet positioned thereon. In this way the user's feet are spaced from the support surface when the user performs core strengthening exercises.

Abstract: A system and method for determining and monitoring a laser ablation volume of a cornea. The method includes sampling a beam of laser shots from a pulsed treatment laser as a reference portion. A fluence distribution of the beam reference portion is measured, and a laser beam characteristic is calculated from the measured fluence distribution. A system for determining and monitoring a laser ablation volume of a cornea includes a beamsplitter that is positioned to split a beam of laser shots from a pulsed treatment laser into a corneal portion and a reference portion. Devices are provided for measuring a fluence distribution of the beam reference portion and for calculating an ablation volume per laser shot from the measured fluence distribution.

Abstract: A system for providing improved vision to a patient having undergone an intraocular lens implantation includes a device for measuring an aberration in an eye of a patient having an intraocular lens implanted therein. Computer software is resident on a processor and is adapted to calculate a refraction profile prescription for correcting the measured aberration. An apparatus is also provided for altering a refractive index of a sector of the intraocular lens in situ according to the calculated prescription. The method includes measuring an aberration in an eye of a patient having an intraocular lens implanted therein, calculating a refraction profile prescription for correcting the measured aberration, and altering a refractive index of a sector of the intraocular lens in situ according to the calculated prescription.

Abstract: The method for the quantification of EEG waveforms along the alertness continuum involves collecting and transforming EEG signal data, identifying and rejecting or decontaminating epochs containing various artifacts, and classifying individual EEG patterns along an alertness-drowsiness continuum. The results of the multi-level classification system are applied in real-time to provide feedback to the user via an audio or visual alarm, or are recorded for subsequent off-line analysis.
