| 20110091146 | OPTICAL MODULATORS EMPLOYING CHARGE STATE CONTROL OF DEEP LEVELS - A method involving: providing an optical waveguide made of a semiconductor material and having a region that is doped by a deep level impurity which creates deep level states in a bandgap in the semiconductor material, the deep level states characterized by an occupancy; passing an optical signal through the optical waveguide and between the region doped by the deep level impurity; and modulating the occupancy of the deep level states to thereby modulate the optical signal. | 04-21-2011 |

| 20090127645 | In-line light sensor - The sensor includes an optical waveguide defined in a light-transmitting medium. The waveguide includes a sensing portion and an non-sensing portion. The light-transmitting medium included in the sensing portion has defects that provide the light-transmitting medium with a deep band gap level between a valence band of the light-transmitting medium and a conduction band of the light-transmitting medium. The deep band gap level is configured such that the waveguide guiding light signals through the light-transmitting medium in the sensing portion causes free carriers to be generated in the light-transmitting medium. A detector is configured to detect the free carriers in the sensing region of the waveguide. | 05-21-2009 |

| 20090053575 | SUPPORTED CATALYSTS FOR THE ANODE OF A VOLTAGE REVERSAL TOLERANT FUEL CELL - In a solid polymer fuel cell series, various circumstances can result in a fuel cell being driven into voltage reversal. For instance, cell voltage reversal can occur if that cell receives an inadequate supply of fuel. In order to pass current, reactions other than fuel oxidation may take place at the fuel cell anode, including water electrolysis and oxidation of anode components. The latter may result in significant degradation of the anode, particularly if the anode employs a carbon black supported catalyst. Such fuel cells can be made more tolerant to cell reversal by using higher catalyst loading or coverage on the anode catalyst support or a more oxidation resistant anode catalyst support, such as a more graphitic carbon or Ti | 02-26-2009 |
| 20090214765 | Fuel Cell Anode Structures For Voltage Reversal Tolerance - A voltage reversal tolerant fuel cell anode structure that includes a gas diffusion layer is prepared by a method that comprises: (a) applying to the gas diffusion layer a first carbon component comprising a sacrificial carbon component having substantially no resistance to corrosion during cell reversal at fuel cell operating temperatures, and (b) applying to the gas diffusion layer a second carbon component. The first carbon material has a BET surface area of at least 350 m | 08-27-2009 |
