Abstract: The disclosure is directed to a system for automatically placing two or more electrodes over different muscle groups. In some embodiments, the system includes an electrode sheet that includes the two or more electrodes. In some embodiments, at least a portion of the two or more electrodes are printed on the electrode sheet, where the printed portion includes a conductive material. In some embodiments, the system includes a garment wrap. In some embodiments, the garment wrap comprises an aperture configured to enable a controller coupling on the electrode sheet to pass through the garment wrap. In some embodiments, the system includes a controller configured to couple to both the garment wrap and the electrode sheet. In some embodiments, the controller is configured to send electrical signals to the two or more electrodes to activate different muscle groups.

A method and apparatus are disclosed for performing an ultrasound scan on a body part and specifically an instrument which directly attaches to the surface of the body. This apparatus provides high resolution images and increased depth of imaging for high resolution ultrasound of targeted subsurface body tissues. Targeted tissues may include joints, ocular structures, and internal organs. The method and apparatus stabilize and provide accurate determination of the position of the body part relative to the ultrasound probe.

Abstract: A method and apparatus are disclosed for a method for securing a patient for a medical procedure and specifically for an innovative headrest system for securing a patient for an ocular imaging procedure. The approach avoids the need for linkages and sliding rods and such. Instead, it relies on three independently movable face rests (two for the forehead or temples and one for the chin) each with a deformable cushion that is urged into conformity with the patient's head and chin during an adjustment phase of operation. Once a comfortable position and suitable conforming shape is achieved, the positions of the face rests are rigidly fixed and the shape of the cushions are rendered rigid and non-deformable, by application of a light vacuum, for the procedural or imaging phase of operation.

Abstract: Embodiments of the present invention are directed to methods of rapidly obtaining ultrasonic images of the eye using a set of procedural options that can be automated by a positioning mechanism that can be controlled by software.

Abstract: A method and apparatus are disclosed for generating accurate and precise ultrasonic images of biological materials or animate objects, such as the cornea and lens of the eye, and, in particular, to an ultrasonic scanning apparatus that can position its virtual center of curvature such that its ultrasonic transducer will emit pulses that reflect substantially perpendicularly from a curved specular surface of interest within the eye. This invention can allow real time imaging of a lens as it accommodates and can better enable researchers and ophthalmic surgeons to develop, fit, implant and diagnose performance of accommodative lenses.
