Abstract: A virtual and augmented reality system comprising an immersive sound system, sensors, a power source, communications, data processing, and an optical system that delivers photoreceptor density resolution, wide angle, high contrast, binocular vision, continuous depth of field images, is integrated for a fully immersive experience. In one embodiment, an optical system comprises a miniaturized array of projectors geometrically arranged to cover retina photoreceptive areas. Projectors provide full spectrum, amplitude modulated, and controllably divergent beams of light that can be steered with one or more degrees of freedom. Segmented projector arrays greatly improve dynamic performance. An adaptive optics reflector includes an array of fixed, or independently controllable optical elements, that can alter reflected beam properties such that a virtual object may appear to be nearer or further from the viewer.

Abstract: An improved virtual reality system comprising an immersive sound system, sensors, a power source, communications, data processing, and an optical system that delivers photoreceptor density resolution, wide angle, high contrast, binocular vision, continuous depth of field, and stabilized images that are closely synchronized with the vestibulo-ocular reflex, providing a comfortable, fully immersive experience. In one embodiment, a miniaturized array of projectors is arranged to cover the retina with adjoining image segments. Each projector provides full spectrum, amplitude modulated, and controllably divergent beams of light that are subsequently reflected off a compound curved reflector, through additional optics, and along reversible light paths to form images on the retina.

Abstract: A contact lens has a first circumferential groove containing a wire coil and an electronics cavity containing one or more electronic devices. The circumferential groove and electronics cavity are formed in a peripheral region of the contact lens. The coil is configured to wirelessly receive electrical power and/or data, and to provide the received power and/or data to the electronic devices in the electronics cavity and to a femtoprojector or other electronic devices in the contact lens.

Abstract: A temporary part is mounted onto the chuck of the diamond turning machine. A diamond turning tip of the diamond turning machine is used to form a reference surface on the temporary part, registering a baseline for a motion control system of the diamond turning machine. While the temporary part remains mounted to the diamond turning machine, a workpiece is mounted onto the temporary part, and the diamond tip is controlled relative to the reference surface to diamond turn a surface profile on the workpiece. Because the baseline established by the reference surface compensates for positional variations from mounting parts directly onto the chuck of the diamond turning machine, the length of the workpiece can be shaped to a designated length with a high degree of accuracy.

Abstract: A shape memory alloy actuator array comprising a plurality of individually trained shape memory alloy actuators to provide relative movement of different actuator array portions and a thin-film heating element positioned adjacent at least one shape memory alloy actuator to thermally activate the actuator for movement away from its initial shape. A shape memory alloy medical device such as a catheter or a conduit is further provided comprising a lattice network or scaffolding of individually activated and oppositely trained shape memory alloy actuators set with a predetermined shape to provide a full range of directional movement within a body, and a network of thin-film heating elements to selectively activate a combination of actuators for movement or variable stiffness.

Abstract: An aneurism patch apparatus for treating an aneurism formed in a vessel includes a vessel interface side and an opposing non-interface side. A patch is formed of a sufficiently flexible material to provide a patch stowed state when the patch is delivered through the vessel and a patch deployed state when the patch is at least partially positioned over the mouth of the aneurism. The interface side of the patch is configured to form an adherence between the patch and an area of a vessel wall adjacent to the aneurism mouth. The adherence maintains a fixed position of the patch relative to the aneurism mouth.

The activation system may be configured for shape memory alloy apparatus and related methods in combination with a control system for selectively activating discrete-shape memory alloy portions with various combinations of at least one heating element that receive an adjustable current such that the resultant local heating causes the sheet to assume a desired overall shape. Methods of forming and selectively activating two-dimensional sheets of electrically conducive and insulative shape memory alloy are further provided.
