Abstract:
Lumen-traveling devices and associated methods and systems are described. Lumen-traveling devices capable of traveling within a body lumen may include a propelling mechanism to produce movement of the lumen-traveling device within the lumen, as well as additional components such as a sensor, an active portion, and/or control circuitry. In some embodiments, a sensor may be used to detect a local condition, and an action may be performed within the body lumen. Actions that may be performed include, but are not limited to, transmitting information, releasing a material within the lumen, performing a surgical step, or collecting a sample, among others.
Abstract:
An electromagnetically responsive element includes an arrangement of controllable self-resonant bodies, such as atoms or quantum dots that form an effective dielectric constant, typically at or near a resonance.
Abstract:
Carbon nanotube template arrays may be edited to form connections between proximate nanotubes and/or to delete undesired nanotubes or nanotube junctions.
Abstract:
Bone cages are disclosed including devices for biocompatible implantation. The structures of bone are useful for providing living cells and tissues as well as biologically active molecules to subjects.
Abstract:
Various embodiments of methods and systems for improving and enhancing vision are disclosed. Adjustable lenses or optical systems may be used to provide adaptive vision modification. In some embodiments, vision modification may be responsive to the current state of the user's visual system. Certain embodiments provide correction of the subject's near and far vision. Other embodiments provide enhancement of vision beyond the physiological ranges of focal length or magnification.
Abstract:
Methods and systems for modifying or enhancing vision are described. In exemplary embodiments, neural or neuromuscular activity is analyzed to determine a focus or other quality of a visual input, and this focus or quality information used as a basis for controlling an adjustable lens system.
