| 20110103408 | BEAM STABILIZED FIBER LASER - A laser head generating ultrashort pulses is integrated with an active beam steering device in the head. Direct linkage with an application system by means of an adequate interface protocol enables the active device to be controlled directly by the application system. | 05-05-2011 |

| 20090283848 | Photodiode Assembly With Improved Electrostatic Discharge Damage Threshold - A photodiode with an improved electrostatic damage threshold is disclosed. A Zener or an avalanche diode is connected in parallel to a photodiode. Both diodes are integrated into the same photodiode housing. The diodes can be mounted on a common header or onto each other. An avalanche photodiode and an avalanche diode can be fabricated on a common semiconductor substrate. A regular p-n diode connected in series, cathode-to-cathode or anode-to-anode, to a Zener diode, forms a protection circuit which, when connected in parallel to a photodiode, provides a smaller electrical capacity increase as compared to a simpler circuit consisting just of a Zener or an avalanche diode. | 11-19-2009 |
| 20100060987 | Optical Device Exhibiting Color Shift Upon Rotation - An optical device exhibiting a color shift upon rotation is disclosed. The optical device has a textured surface having a relief structure finer than a human eye resolution but large enough not to exhibit diffraction effects. The textured surface is coated with an interference thin film that exhibits a color shift with tilt. A uniform color seen at one angle of rotation changes to another uniform color when the optical device is rotated in its own plane. A method of manufacturing of such an optical device, as well as the use of the optical device as an optical security and authentication element, is also disclosed. | 03-11-2010 |
