Abstract: A method of generating a high precision optical surface profile includes obtaining a high precision optical surface profile which contains information of the optical path difference map of the profile. A substrate material has a known index of refraction, Ns, while a cover material has an index Nc that is more closely matched to the index Ns of the substrate material than the index of air Nair to Ns. An exaggerated surface profile is cut that is proportionally expanded from the high precision profile by a factor: (Ns?Nair) divided by (Ns?Nc). The cut surface profile is covered with the cover material.

Abstract: A contact lens providing high visual acuity with the comfort of a soft lens includes a thin layer of hard lens material at the front surface of the contact lens; and a second soft lens material layer at the posterior portion of the lens. The soft lens provides a contact area substantially in contact with the central region of the cornea. The first layer is bonded on top of the second layer directly or through a third elastic material layer. Manufacturing methods overcome problems of swelling of the soft lens component during hydration.

Abstract: A wavefront device (FIG. 1A) produces adjustable amplitudes in optical path differences and adjustable axis orientation angles, two substantially identical wave plates (225) have a wavefront profile of at least the third order Zernike polynomial function which are not circularly symmetric, as denoted by Z(i,j) where i>3 and jO. The wave plates are mounted in rotatable mounts (124) with their optical centers substantially aligned with each other.

Abstract: A subjective refraction technique uses a plane wave light source including substantially a point as a viewing target. The refraction method provide for a number of distinct identifiable end points. By finding such end points the process leads to an aberration-corrected vision. A defocus corrector assembly (DCA) includes a lens that is moveable along an optical axis between a patient's eye and the point light source for adjusting defocus power until the patient indicates that the blurry image has become a relatively focused line image. An astigmatism corrector assembly (ACA) which is capable of continuously variable in its amplitude is provided including a pair of astigmatism plates for adjusting astigmatism power and axis angle. The ACA is adjusted until the patient indicates that the line image has become a substantially round image. A reference marker provides displayed items including a sweep line overlapping at the point source and having an orientation which is adjustable.

Abstract: A beam of electronic charges and a standing wave laser beam are generated. The beam of charges is collided with the standing wave laser beam at a substantial angle to generate a burst cone of high energy x-rays. The x-ray cone is split, collimated and steered to a collapse point of diagnosis within a patient's body. A selected volume of the patient's body is scanned for diagnosis by directing subsequent burst cones at an array of points within the volume. The fluorescence spectra are detected from each of the points resulting from the high energy x-ray scanning. A chart is generated distinguishing fluorescence spectra emitted from various points within the volume.

Abstract: A glucose monitoring system, includes a glucose sensor strip or package of strips. The strip includes a substrate and a glucose monitoring circuit that has electrodes and a bodily fluid application portion of selected chemical composition. An antenna is integrated with the glucose sensor strip. A RFID sensor chip is coupled with the glucose sensor strip and the antenna. The chip has a memory containing digitally-encoded data representing calibration and/or expiration date information for the strip.

Abstract: A sensor array designed to be continuously indexed through a compatible blood glucose test monitor for the purpose of conducting multiple consecutive blood glucose measurements. The sensor array can be configured to substantially conform to a non-planar surface. In one embodiment, the sensor array includes first and second test sensors which are hingedly coupled together through a pin and socket interconnection. In another embodiment, the sensor array includes a unitary, non-conductive substrate which is scored to define one or more fold lines, a first set electrodes deposited on the substrate to define a first test sensor, and a second set of electrodes deposited on the substrate to define a second test sensor.

Abstract: A method, apparatus, and computer-readable media include receiving a signal representing a request from a remote user for a secure resource residing on a network employing a generic application-layer network protocol; determining, without the intervention of the user, the type of security credential required to access the secure resource; and sending a signal representing a second request to the secure resource, the second request including a security credential for the user of the type required to access the secure resource.

Abstract: A data handling method combines search capabilities with analytical functionality. The invention provides advantages when dealing with structured documents (such as electronic catalogs, XML documents, text documents, HTML documents, Internet documents, etc.) and other data stored in a computer system. Various embodiments include simplified ways to express search/analysis requests of a data set and also to express results to such requests.
