  • Methods and apparatus to make substantially uniform losses in optical cross connects
    Patent number: 8270785
    Abstract: A method for cross connecting optical signals includes using a common beam steerer to direct a set of optical signals from a set of input ports to a set of output ports. The method further includes adjusting a curvature of the common beam steerer so that paths of the optical signals have substantially the same effective path length.

  • Method and composition for delivery of medicants to animals
    Patent number: 8088408
    Abstract: According to the present invention, a vaccine or pharmaceutical-containing composition is applied to the muzzle area of the animal, which will then naturally use its tongue to clean itself. This behavior will cause the animal to deposit applied composition to the mucosa of the nasal and oral cavities, thus meeting the need for a simple, effective, and efficient vaccination or treatment method.

  • Method of manufacturing semiconductor device
    Patent number: 7994021
    Abstract: A method of forming a semiconductor device is provided, including a step of forming a layer which absorbs light over one face of a first substrate, a step of providing a second substrate over the layer which absorbs light, a step of providing a mask to oppose the other face of the first substrate, and a step of transferring the part of the layer which absorbs light to the second substrate by irradiating the layer which absorbs light with a laser beam through the mask.

  • Apparatus and method of blockage detection
    Patent number: 7791475
    Abstract: An apparatus includes a mounting base and a compatible electrical unit removably carried on the base. The base carries a transducer and a sensor external to the unit. The transducer emits radiant energy toward the unit. The sensor receives radiant energy modulated by the unit. A local control unit can store the received, modulated radiant energy as a base-line profile. Subsequently, additional profiles can be generated and compared to the stored base-line to determine is a spatial characteristic of the electrical unit has changed.
