  • Patent number: 8270676
    Abstract: A method for the automatic light control for a motor vehicle with a camera sensor for monitoring the environment in front of the motor vehicle is presented. With the camera sensor, an image sequence of the motor vehicle environment in front of the motor vehicle is recorded. The lane of the own motor vehicle is estimated from the image data. At least one evaluation window along the lane is set in the image, so that preceding and oncoming motor vehicles are recorded. Points of light in the image sequence are pursued (tracked). On the basis of the image data, the lights of other motor vehicles are detected, and the front headlights are controlled in such a manner that the drivers of other motor vehicles are not blinded.

  • Patent number: 8218009
    Abstract: A method for detecting and categorizing points of light for a motor vehicle with a camera sensor directed towards the motor vehicle environment is presented. Here, at least one first category for passive, illumined reflectors and at least one second category for self-radiating, moving lights, in particular motor vehicle lights, is provided. For this purpose, the time progression of the intensity of a point of light is analysed. On the basis of the intensity fluctuation, points of light are categorized as motor vehicle lights or as reflectors.

  • Publication number: 20110228089
    Abstract: A method is disclosed for distinguishing between approaching vehicle lights (VL) and retroreflectors (R) in the dark, which are recorded as light surfaces by an image recording device oriented towards the surroundings of a vehicle. The image recording device records at least one image of the vehicle surroundings. The image is evaluated by an image processing unit. Light surfaces present on the image are analyzed. A decision is then taken as to whether the light surface is a vehicle light (VL) or a retroreflector (R). Light surfaces whose optical interaction with other objects is shown in the image are identified as vehicle lights (VL).

  • Publication number: 20100316258
    Abstract: A method for determining at least one threshold value S for distinguishing, in the dark, between reflectors and vehicle lights that are recorded as light spots by a camera sensor oriented towards the surroundings of a vehicle. The camera sensor records a series of images of the surroundings of the vehicle. At least one light spot in the series of images is tracked. When the tracking of a light spot is completed, at least one parameter (for example the maximum intensity Imax of the light spot in the entire series of images, or the lifetime ? of the light spot) is determined from measured values, for example from the intensity of the light spot in each image. The threshold value S is then adapted to the determined parameter/s. The determined parameter value of the light spot is included in a frequency distribution of the parameter values from previously tracked light spots.

  • Publication number: 20100271197
    Abstract: An apparatus for a vehicle that has a propulsion mechanism capable of causing injury to a bystander located proximate to the propulsion mechanism when the propulsion mechanism is started comprises an activation switch, a speaker, and a sound controller. The activation switch is accessible to an operator of the vehicle. The sound controller is operative to cause the speaker to emit an audible warning in response to an activation of the activation switch prior to the propulsion mechanism being started.

  • Publication number: 20100163153
    Abstract: This invention relates to a particle agglomeration process of wood and cork which uses an agglomerating system consisting of a pre-polymer of hydroxyl terminated polybutadiene (HTPB), a di-isocyanate and possibly a catalyst in order to obtain agglomerations of cork and/or wood particles with new characteristics and with new particle compositions. These products are used in the particle agglomeration industry in the wood sector (wood particles boards), specifically in the panels and veneers sub-sector and in the cork agglomeration industry sub-sector. This process enables the industrial reprocessing of residues and sub-products of sectors of wood and cork and at the same plays its part towards solving environmental problems by creating a viable and profitable alternative to storage and/or burning and/or depositing in the ground, in particular for what is referred to as cork powder and ‘terras’ and some wood residues, in particular fibre and polishing dust.

  • Publication number: 20100081734
    Abstract: This invention refers to an agglomeration process of wood fibres which consists of an impregnation and/or pulverisation of fibres with a pre-polymer of hydroxyl terminated polybutadiene (HTPB), a di-isocyanate and possibly a catalyst to obtain slabs of fibre agglomerations (fibreboards). The<b></b>agglomerating system used in the process is formaldehyde-free. It is therefore an alternative to the current processes that use formaldehyde-based agglomerates and also fulfils the most demanding environmental criteria. This<b></b>process aims to produce agglomerated fibreboard slabs in different densities such as medium density fibreboard (MDF) and high density fibreboard (HDF) which have better physical and mechanical properties resulting therefore in a better quality product and therefore also enabling exemplary quality slabs to be obtained irrespective of the nature of the wood fibreboard whether it is hardwood or resin-based.

  • Patent number: 7202691
    Abstract: A non-contact method is described for acquiring the accurate charge-voltage data on miniature test sites of semiconductor wafer wherein the test sites are smaller than 100 ?m times 100 ?m. The method includes recognizing the designated test site, properly aligning it, depositing a prescribed dose of ionic charge on the surface of the test site, and precise measuring of the resulting voltage change on the surface of the test site. The method further compromises measuring of the said voltage change in the dark and/or under strong illumination without interference from the laser beam employed in the Kelvin Force probe measurement of the voltage. The method enables acquiring of charge-voltage data without contacting the measured surface of the wafer and without contaminating the wafer. Thus, the measured wafer can be returned to IC fabrication line for further processing.
