20100040098 | LASER DIODE ILLUMINATOR DEVICE AND METHOD FOR OPTICALLY CONDITIONING THE LIGHT BEAM EMITTED BY THE SAME - A laser diode illuminator device and a method for optically conditioning the output beam radiated from such a device, so that highly-demanding illumination application requirements that call for high output powers within a specified field of illumination can be addressed. At the heart of the device is a two-dimensional stack of laser diode bars wherein the linear array of beamlets radiated by each laser diode bar is optically conditioned through its passage in a refractive-type micro-optics device followed by a cylindrical microlens. The micro-optics device performs collimation of the linear array of beamlets along the fast axis of the bars, and it also acts as a beam symmetrization device by interchanging the divergences of the laser beamlets along the fast and slow axes. The cylindrical microlens is for collimation of the beamlets along the slow axis. The optical conditioning is performed individually for each linear array of beamlets so that the radiance or brightness of the laser diode illuminator can be optimized while any specified field of illumination can be filled with an excellent uniformity of the radiant intensity. | 02-18-2010 |
20110007997 | FIBER-OPTIC TEMPERATURE SENSOR ASSEMBLY - A fiber-optic temperature sensor assembly comprises a cap with an inner cavity. A sensor member is received in the inner cavity of the cap. The sensor member has light-transmitting properties adapted to change with temperature variations. An optical fiber has a first end received in the inner cavity of the cap, and a second end of the optical fiber being adapted to be connected to a processing unit for transmitting light signals between the sensor member and the processing unit. A pressing device is received in the cap and pressing against the sensor member such that the sensor member is in operational contact with the first end of the optical fiber for transmission of light therebetween during operation of the fiber-optic temperature sensor assembly. | 01-13-2011 |
20110280265 | DRIVER CIRCUIT FOR THE DIRECT MODULATION OF A LASER DIODE - A driver circuit for a laser diode provides drive signals to the electrodes of the laser diode based on a pulsed input signal. An input receives the pulsed input signal and launches it into an amplification stage which preferably includes dual amplifiers, a buffering stage and a biasing stage. The output of the laser diode is an optical signal that reproduces the pulsed input signal with high fidelity and low amplitude noise. In one embodiment, the input separates the pulsed input signal into two signal components, launched in respective inverting and non-inverting branches which each include successive amplification, buffering and biasing stages. | 11-17-2011 |

20120225573 | TURBO MACHINE ELECTRICAL CONNECTION ELEMENT - An electrical connection element for a turbine engine, including conductors connected to a connector by a tubular coupling surrounding one end of the conductors, and an insert providing protection against wear of the conductors being mounted in the tubular coupling. The insert includes a substantially tubular central body containing the conductors and provided over at least a fraction of its length with a series of spacers bearing against an inside surface of the tubular coupling of the connection element so as to hold the central body at a distance from the inside surface. | 09-06-2012 |
