Filed:

Jan 29, 2002

Appl. No.:

10/060462

Inventors:

Stanley G. Froyd - Carpinteria CA, US
Michael Little - Santa Barbara CA, US

Assignee:

Occam Networks - Santa Barbara CA

International Classification:

G06F 15/177
G06F 15/16

US Classification:

709220, 709203, 709217, 709221, 709222

Abstract:

A framework is used for delivering data to and from a system. The framework consists of different delivery vehicles or forms to carry different types of data to and from the system. The data contains configuration information. When storing the configuration information, the framework allows the configuration information from the system to be filled in the forms. The configuration information is converted into a Generalized Markup Language (GML) format.

International Classification:

G02B 2608

US Classification:

359293

Abstract:

The present invention provides a Schlieren projection system with a large aperture reflective imager. The combination of a beam-addressed CCM design with flat-panel manufacturing techniques configuration produces a large aperture imager that overcomes the problems of limited deflection range, high beam current, electrostatic instability and limited resolution associated with known electrostatically-actuated micromirror targets. The CCM imager includes a thin insulating membrane that decouples the electron beam from the micromirror array. Decoupling also allows the mirror to be designed to optimize reflectivity, exhibit a higher resonant frequency for better video performance, and be fabricated simultaneously with the hinges. The CCM imager is fabricated using flat-panel manufacturing techniques that are ideally suited to producing large aperture devices at low cost.

International Classification:

US Classification:

Abstract:

A micromirror light valve target configuration that overcomes the problems of limited deflection range, electrostatic and resolution by forming the secondary electron collector grid of a fine conductive mesh and placing it in close proximity to the micromirror array. The source, preferably a fixed beam array, addresses the micromirror array such that it exhibits a secondary emission coefficient less than one to write a negative charge pattern onto the mirrors so that they are attracted to the collector grid. If the anode is also in close proximity to the array, the mirrors can be addressed so that they deflect up toward the grid and down toward the anode thereby increasing the deflection range.

Assignee:

MEMSolutions, Inc. - Westlake Village CA

International Classification:

G02B 2602
G02B 2608

US Classification:

359293

Abstract:

A beam addressed electrostatically-actuated charge controlled mirror (CCM) with frame time utilization approaching 100% is provided by partially coating the CCM's pixelized beam addressing surface with a material having the opposite electron affinity. Each pixel of the pixelized beam addressing surface has first and second portions that exhibit secondary emission coefficients that are respectively less than and greater than one for the same beam energy. A beam or beams that are capable of subpixel resolution selectively address each pixel's first and second portions to control the amount of charge on the pixelized beam addressing surface and its localized potentials.

Abstract:

An electrostatically actuated micromirror light modulator that exhibits increased deflection range, better charge efficiency and improved electrostatic stability. A thin insulating membrane decouples the electron beam from the micromirror array inside the vacuum cell. The membrane is just thick enough to stop the incident electrons from penetrating through to the mirrors but is thin enough to maintain resolution of the deposited charge pattern. An equipotential layer beneath the mirror array prevents any attractive force from being developed due to the accumulation of static charge on the surface of the light modulator that may otherwise cause the mirror to snap-over and become stuck to the substrate.
