20150298813 | DISTRESS BEACON SYSTEM FOR AN AIRCRAFT OR ANOTHER VEHICLE - A versatile distress beacon system for an aircraft, a ship or other vehicles, including a beacon and a mounting to provide the function of an automatic beacon or a survival beacon. The automatic distress beacon system includes a mounting rigidly attached to the structure of the aircraft and a beacon removably mounted on the mounting. The mounting includes an electronic management unit having a first connector to connect to the data bus and to control the aircraft to receive data from the data bus and orders to activate the beacon, and a second connector to connect to the beacon to transmit data and activation orders to same. The beacon having a memory module to store the transmitted data and a radio transmission module connected to a transmission antenna. The mounting has a detector to detect abnormal events connected to the electronic management unit, with a view to activating the beacon. | 10-22-2015 |

20150353843 | METHODS AND APPARATUSES FOR REMOVING SULFUR COMPOUNDS FROM A HYDROCARBON STREAM - Methods and apparatuses are provided for removing sulfur compounds from a hydrocarbon stream. A method includes contacting a hydrocarbon feed stream with a basic aqueous solution in an extractor to produce a sweetened hydrocarbon stream and a rich stream, where the rich stream includes a mercaptan salt. The rich stream is contacted with oxygen in an oxidizer to convert the mercaptan salt into a disulfide and to produce an oxidizer effluent stream. The oxidizer effluent stream is separated into a gas recycle stream and a mixed disulfide stream, and the gas recycle stream is combined with the rich stream. | 12-10-2015 |

20120008137 | Active Planar Autofocus - A system for inspecting a constant layer depth relative to a particular device layer. The system has an image sensor with a fixed focal plane. A focus sensor senses the surface topography of the substrate and outputs a focus data stream. A stage moves the substrate in an XY plane, and a motor moves the substrate in a Z dimension. A controller operates the system in one of a setup mode and an inspection mode. In the setup mode the controller controls XY movement of the substrate so as to scan a first portion of the substrate. The controller receives the focus data stream, concurrently receives XY data, and stores correlated XYZ data for the substrate. In the inspection mode the controller controls XY movement of the substrate so as to scan a second portion of the substrate. The controller receives the focus data stream, concurrently receives XY data, and subtracts the stored Z data from the focus data stream to produce a virtual data stream. The controller feeds the virtual data stream plus an offset to the motor for moving the substrate up and down during the inspection, thereby holding the focal plane at a desired Z distance, regardless of the surface topography of the substrate. | 01-12-2012 |
20130321797 | SUPER RESOLUTION INSPECTION SYSTEM - The disclosure is directed to a system and method for inspecting a sample by illuminating the sample at a plurality of different angles and independently processing the resulting image streams. Illumination is directed through a plurality of pupil apertures to a plurality of respective field apertures so that the sample is imaged by portions of illumination directed at different angles. The corresponding portions of light reflected, scattered, or radiated from the surface of the sample are independently processed. Information associated with the independently processed portions of illumination is utilized to determine a location of at least one defect of the sample. Independently processing multiple image streams associated with different illumination angles allows for retention of frequency content that would otherwise be lost by averaging information from multiple imaging angles. | 12-05-2013 |
20140285657 | Inspection System Including Parallel Imaging Paths with Multiple and Selectable Spectral Bands - The present disclosure is directed to a system for inspecting a sample with multiple wavelengths of illumination simultaneously via parallel imaging paths. The system may include at least a first detector or set of detectors configured to detect illumination reflected, scattered, or radiated along a first imaging path from a selected portion of the sample in response to the first wavelength of illumination and a second detector or set of detectors configured to concurrently detect illumination reflected, scattered, or radiated along a second imaging path from the selected portion of the sample (i.e. the same location on the sample) in response to the second wavelength of illumination, where the second imaging path may at least partially share illumination and/or detection optics with an autofocus channel. | 09-25-2014 |

20080213029 | Promotional writing instrument having objects within fluid-filled chambers - A promotional writing instrument includes an elongated barrel having a writing end and first and second longitudinally adjacent transparent chambers. Translucent fluid substantially fills the first and second chambers, and a first object is disposed within the first chamber and a second object is disposed within the second chamber. Movement of the first and second objects is viewable through the transparent first and second chambers. A portion of the barrel between the first and second chambers is substantially non-transparent and blocks from view adjacent respective portions of the first and second chambers. When the first object moves downwardly through the fluid in the first chamber, the first object disappears behind the barrel non-transparent portion substantially at the same time as the second object appears from behind the barrel non-transparent portion as the second object moves downwardly through the fluid in the second chamber. | 09-04-2008 |
