Abstract: Generating an aspheric contact lens design for facilitating myopia control of a cornea of a patient includes operations of: obtain measurement for degree refractive error of the eye in diopters; obtain measurement of one or more biomechanical properties of the cornea; define a diameter of a central zone of the contact lens based on pupil size; select a base curve profile and width for the central zone based on the refractive error and the one or more biomechanical properties; define a width of a reverse zone adjacent to and encircling the central zone, the width being greater than 0.5 mm; select a reverse curve profile for the reverse zone compatible with the base curve profile; modify the base curve profile adjacent to the reverse zone by applying a selected base eccentricity curve profile for enhancing the tension force strength of the reverse zone; define a width of a relief zone of the contact lens adjacent to and encircling the reverse zone; select a relief curve profile for the relief zone; define a width of an alignment zone of the contact lens adjacent to and encircling the relief zone; select an alignment curve profile for the alignment zone; and define a width of a peripheral zone of the contact lens adjacent to and encircling the alignment zone; select a peripheral curve profile for the peripheral zone; wherein the compression force strength and the tension force strength of the contact lens cooperate to reshape corneal curvature in a mid-peripheral region to address the myopia control when the contact lens is applied to the eye.

Abstract: This invention is in the field of controlled elution devices for therapeutic delivery. There exists a need for a stand-alone capable device for the localized and extended delivery of a therapeutic. This need is overcome by the present invention having an exemplary embodiment comprised of a microfilm base (12), a reservoir of a therapeutic (14) disposed about the microfilm base (12) and a top layer (24) that is (i) a plurality of laminated layers (24) of para-xylyelne polymer and/or (ii) para-xylyelne polymer endowed with oxidatively functionalized para-xyele units. The thicknesses of the device is optimally in the range of about 10 to about 200 microns. The device is usable for the localized release of broad spectrum therapeutics for interventional and preventative medicine.

Abstract: A circuit switching system in an M-ary, n-cube connected network completes a best-first path from an originating node to a destination node by latching valid legs of the path as the path is being sought out. Each network node is provided with a routing hyperswitch sub-network, ("HSN") connected between that node and bidirectional high capacity communication channels of the n-cube network. The sub-networks are all controlled by routing algorithms which respond to message identification headings ("headers") on messages to be routed along one or more routing legs. The header includes information embedded therein which is interpreted by each sub-network to route and historically update the header. A logic circuit, available at every node, implements the algorithm and automatically forwards or back-tracks the header in the network legs of various paths until a completed path is latched.
