Abstract: A content-presenting apparatus may include an output device configured to output to a user content of a content unit in a form sensible to a user. A storage device may store a collection of interrelated content units having a sequence link to at least one other content unit. A plurality of the content units may have sequence links to at least three other content units. A sequence link may be to a content unit that does not have a sequence link back to the same content unit. A processor may be configured to output on the at least one output device content units sequentially in response to inputs received from the user on at least one input device, receive on the at least one input device an indication input by the user that correlates to a sequence link back to a content unit not having a reciprocal sequence link.

Abstract: An adaptive content system may include a storage system, a development module, and a presentation module. The storage system may store populated and unpopulated content units configured to contain information content and at least one sequence link selectable by a user for establishing a sequence in which the content units are presented to a user. The development module may populate or modify a stored content unit. The presentation module may access the storage system to retrieve content units for presentation on an output device in response to inputs received from an input device without allowing modification of the information content populated on the content units.

Abstract: An instructive content creation and viewing system, including a first microprocessor assembly, an intuitive viewing interface, a second microprocessor assembly in communication with the first microprocessor assembly, and an content creation interface. The viewing interface is housed on the first microprocessor assembly and the content creation interface is housed on the second microprocessor assembly. The content creation interface is used to create the instructive content, while the first microprocessor assembly obtains the instructive content. The viewing interface presents the instructive content while the viewing interface adapts to the instructive content and user preferences or actions.

Abstract: A method and system for improved material processing using a laser beam. The method and system includes directing a laser beam above, at or below the surface of the material in one or more preferred patterns and with preferred laser pulse characteristics specific to the material to reduce or mitigate the accumulation or effects of gas, debris, fluid, or other by-products of photodisruption either at the location where additional laser pulses are being placed or in other sensitive locations in the material.

Abstract: An improved applanation lens and method for use in an interface between a patient's eye and a surgical laser system does not discolor or lose light transmittance when subjected to gamma radiation. The improved applanation lens has an applanation surface configured to contact the eye upon application of a pressure. The lens is formed of high purity silicon dioxide (SiO2) with purity great enough to resist discoloration upon prolonged irradiation by high-energy radiation such as UV, x-rays, gamma rays or neutrons, and is preferably a fused silica.

Abstract: The improved applanation lens is formed of SiO2 with purity great enough to resist discoloration upon prolonged irradiation by high-energy radiation such as UV, x-rays, gamma rays or neutrons. The lens can be used in an interface, adapted to couple a patient's eye to a surgical laser, in which the interface includes an attachment apparatus adapted to overlay the anterior surface of an eye and for stable engagement to the eye. An applanation lens has an applanation surface configured to contact the eye and applanate or flatten the anterior surface of the eye upon application of a pressure. The surface is bounded by a plane and coupled to a delivery tip of the surgical laser such that the delivery tip is referenced to the plane. The applanation lens is formed of high purity SiO2, preferably a fused silica. The applanation lens must have a transmittance of greater than 90% for wavelengths of light from 275 nm-2500 nm, particularly for a wavelength of about 1053 nm.
