Transmissive, optically addressed, photosensitive spatial light modulators and color display sys |
August 2, 2011 |
| An optically addressed, photoconductive spatial light modulator (SLM) operates in a transmissive mode and is capable of modulating a wide spectrum of visible light. There is no pixel structure or native pixel resolution in the SLM. The SLM has no photodiodes and does not rectify. A l |

Hollow reinforcing members and composites containing the same |
March 6, 2001 |
| There is disclosed a hollow reinforcing element for casting into composites, which in use defines passageways that may communicate to the exterior of the composite and that can serve as conduit arrays in structures formed from the composite. Benefits include superior strength to weig |
