| Number | Title | Issue Date |
| 7776794 | Biosensor using living cells on silicon-based microarrays The invention relates to a biosensor comprising living cells that express a chemosensor, or receptor, on their surface. When grown on a microarray comprising electrodes, the cells can be induced, by binding of a ligand to the receptor, to secrete a molecule. This se... | 08/17/2010 |
| 7618838 | Hybrid solar cells based on nanostructured semiconductors and organic materials A method for forming a photovoltaic cell which includes forming a nanostructured layer in a semiconductor material having a plurality of pores opening onto a surface, the plurality of pores having a depth greater than about 1 micron and a diameter between about 5 na... | 11/17/2009 |
| 7527997 | MEMS structure with anodically bonded silicon-on-insulator substrate A silicon-on-insulator (SOI) substrate is anodically bonded to a glass substrate in a MEMS structure with or without electrically bypassing the insulator layer by electrically comprising the silicon layers. The insulator layer serves as an etch stop to create a well... | 05/05/2009 |
| 6701036 | Mirror, optical switch, and method for redirecting an optical signal An optical switch for redirecting an optical signal includes a plurality of spaced-apart mirrors disposed in an array for detecting and reflecting one or more optical signals. The mirrors include a reflective member and a sensor. Desirably, the optical si... | 03/02/2004 |
| 6421179 | Wavelength division multiplexing system and method using a reconfigurable diffraction grating The present invention provides an improvement in a wavelength division multiplexer and/or a dense wavelength division multiplexer (WDM/DWDM) by incorporating an electronically reconfigurable diffraction grating. The introduction of the electronically reco... | 07/16/2002 |
| 6341526 | Micromachined diffractive pressure sensor system An improved optical pressure sensor determines the pressure of the fluid to be monitored by the deflection of a diaphragm in the pressure chamber of the sensor which has an inlet from the measured vessel. The deflection of the diaphragm is determined by m... | 01/29/2002 |
| 6282213 | Tunable diode laser with fast digital line selection An improved tunable diode laser is capable of fast digital line selection over a broad wavelength spectrum, and uses no moving parts. A focusing element, such as a mirror or a lens, used in combination with a micromirror array serves as the retroreflector... | 08/28/2001 |
| 6078392 | Direct-to-digital holography and holovision Systems and methods for direct-to-digital holography are described. An apparatus includes a laser; a beamsplitter optically coupled to the laser; a reference beam mirror optically coupled to the beamsplitter; an object optically coupled to the beamsplitte... | 06/20/2000 |
| 5999319 | Reconfigurable compound diffraction grating A reconfigurable compound diffraction grating is fabricated using microelectomechanical systems (MEMS) technology. The compound grating structure can be viewed as the superposition of two separately configured gratings. A common lower electrode is placed ... | 12/07/1999 |
