Abstract:
A method provided for manufacturing a lensed tip optical fiber. The method includes providing an optically transparent cylindrical fiber; and etching a first end of the optically transparent cylindrical fiber to form a tip. The tip is heated which forms a lens surface at the heated tip.
Abstract:
Systems and methods are disclosed herein to provide zoom and/or autofocus lenses. For example, in accordance with an embodiment of the present invention, a lens is provided with at least one tunable lens. The focal length and/or focus of the lens may be varied without mechanically moving or changing the separation between one or more lens components.
Abstract:
In one embodiment, a color projection system includes a lamp; at least one prism configured to diffract light from the lamp into a diffracted beam; and an LC microdisplay panel or MEMS panel configured to receive the diffracted beam from the at least one prism, wherein by moving the at least one prism with respect to the light from the lamp, the diffracted beam received by the LC microdisplay or MEMS panel sequentially comprises a diffracted red beam, a diffracted blue beam, and a diffracted green beam, the LC microdisplay panel or MEMS panel being configured to sequentially modulate the diffracted red beam into a red sub-frame of an image, the diffracted green beam into a green sub-frame of the image, and the diffracted blue beam into a blue sub-frame of the image.

Abstract:
A device and method for forming a device including electron emitters. The method includes exposing a first face of a sheet of bundled fiber segments to a reactive liquid to allow first ends of the fiber segments to react with the reactive liquid to remove material therefrom. A coating material is deposited on the first face which has the material removed. The method also includes exposing a second face of the sheet of bundled fiber segments to a reactive liquid to allow second ends of the fiber segments to react with the reactive liquid to remove material therefrom to expose the coating material.
Abstract:
A color projection system includes a lamp and at least one diffraction grating or at least one prism that diffracts light from the lamp onto an LC microdisplay panel. By moving either the at least one diffraction grating or the at least one prism with respect to the incident light from the lamp, the diffracted light received by the LC microdisplay panel sequentially comprises red, green, and blue light.

Abstract:
A method of forming a field emission device and the resulting device including emitters formed of fiber segments. Tips are formed on the fiber segments that have a radius substantially small by exposing the tips to a reactive liquid for a duration of time The tips are coated with a low work function conducting material to form emitters.
Abstract:
An implantable bioartificial active secretion system for providing a physiological secretion such as insulin necessary for functionality of a physiologic activity such as glucose metabolism of a living-being host. The system includes a housing implantable within the host in fluidic communication with tissue fluid indicative of secretion need. A chamber within the housing contains a plurality of physiologically active, autonomously functioning, live secretory cells for producing the physiological secretion. A periodically operating pump apparatus moves tissue fluid into contact with the secretory cells for pick up of the regulating physiological secretion for subsequent physiologically-effective dispensing into the host while avoiding immunorejection of the host body or of the host to the secretory cells.
