  • Spectral conditioning mechanism
    Publication number: 20060227824
    Abstract: An optical assembly is disclosed. The optical assembly includes a laser having a front facet and a rear facet a thin film filter (TFF) to receive a first optical signal from the front facet of the laser and to reflect a component of the first optical signal back to the laser a back facet monitor (BFM) to receive a second optical signal and the reflected component from the rear facet of the laser and a feedback circuit to monitor the quantity of reflected component.

  • Memory aid
    Publication number: 20060073450
    Abstract: A memory aid comprising a display having a plurality of display zones (19), each display zone adapted to provide a display independently of the other display zones, each display zone capable of sequentially displaying the letters of an alphabet and a control adapted to cause the sequential display of the letters at each display zone. An electronic device and a mechanical device and a software programme which is adapted to control a computer is claimed.

  • Incubated Bragg gratings in waveguides
    Patent number: 5574810
    Abstract: A Bragg reflection grating is written in photosensitive optical fiber using ultra-violet light from an ArF excimer laser with the aid of a phase grating to create a fringe pattern. The writing is effected by a type II damage process performed in two stages, the first of which involves the creation of a low reflectivity grating, which is incubated to greater reflectivity in the second stage. Incubation is performed without the use of any fringe pattern.

  • Production of hydrocarbons
    Patent number: 4021501
    Abstract: In the thermal cracking of a hydrocarbon feedstock, the quenching of the gases leaving the cracking zone is deliberately deferred for a very short time to permit continued endothermic reaction and thereby increase the ethylene yield.
