Patent Number Title Of Patent Date Issued
7990600 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
6197395 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
5672214 Concrete solar cell September 30, 1997
An inexpensive, robust concrete solar cell (10) comprises a photovoltaic material embedded in and extending beyond front and rear major surfaces (18 and 16) of a matrix layer (14). The matrix layer typically comprises a high-strength, cementitious material, such as a macrodefect-free cem
