Abstract: A foot, toe, and ankle exercise device provides variable resistance to movements in multiple directions. The device comprises a flexible forefoot support to allow for full toe and foot range of motion. The forefoot support includes a raised surface under the toes used to help align anatomical landmarks to delineate the resistance for the toes from that of the foot/ankle. Resistance may be provided by elastic banding or tubing that is mounted on an octagonal frame. Tensioners are provided to adjust the magnitude of the resistance. A height adjustable heel cup is mounted on a horizontal track to adjust the apparatus for use by different users with different size feet. A vertical track is provided to raise or lower the forefoot support and system of elastic banding or tubing so that full range movements are possible. In another version of the invention, inelastic banding along with weights is used to provide resistance.

Abstract: A sensor assembly for monitoring physiological characteristics interfaces to a subject's ear. The sensor assembly has a projection that projects into the subject's concha. The projection may have a notch to accommodate the subject's anti-tragus. A clip connected to the projection holds a sensor against the subject's lobule. The sensor may comprise a pulse-oximetry-type sensor.

Abstract: An apparatus for ultrasound scanning of the eye is provided comprising a virtual center translocation mechanism that facilitates precise arcuate motion of an ultrasonic transducer to maintain focal distance from the eye and to maintain normality of the ultrasound beam with surfaces of the eye. The invention also provides a radius adjust mechanism for changing the radius of ultrasound scanning to facilitate positioning of the transducer focal point on selected surfaces of the eye. Centration optics are also provided, for aligning the ultrasound transducer with the Purkinje (or other optical or geometric) axis of a patient's eye. In addition the invention provides a hygiene barrier eyeseal for protection of the patient from disease propagation.
