  • Patent number: 10867401
    Abstract: A method and device for determining an ego-motion of a vehicle are disclosed. Respective sequences of consecutive images are obtained from a front view camera, a left side view camera, a right side view camera and a rear view camera and merged. A virtual projection of the images to a ground plane is provided using an affine projection. An optical flow is determined from the sequence of projected images, an ego-motion of the vehicle is determined from the optical flow and the ego-motion is used to predict a kinematic state of the car.

  • Patent number: 10719955
    Abstract: The application provides a method of calibrating a camera of a vehicle. The vehicle has a reference frame. The method comprises taking an image of a scene by the camera. The ground plane of the vehicle is then determined according to features of the image. An origin point of the vehicle reference frame is later defined as being located on the determined ground plane. A translation of a reference frame of the camera is afterward determined for aligning the camera reference frame with the vehicle reference frame.

  • Patent number: 10652466
    Abstract: A method and a device for image stabilization of an image sequence of one or more cameras of a vehicle are disclosed. Images of the surroundings of the vehicle are recorded and image points of the recorded images are projected to a unit sphere, where the projection includes applying a lens distortion correction. For each of the one or more cameras, a vanishing point is calculated using the projected image points on the unit sphere and a motion of the vanishing point on the unit sphere is tracked. The motion of the vanishing point is used to calculate a corrected projection to a ground plane.

  • Publication number: 20160280135
    Abstract: In an embodiment, an animal detection system (11) includes a surround view system (12), a location determination system (13) and a processing module (14). The processing module (14) is configured to receive data from the surround view system (12) and receive data regarding the location of the vehicle (10) from the location determination system (13). The processing module (14) is configured to determine if the location of the vehicle (10) is within an animal zone, and if the location of the vehicle (10) is within an animal zone, to process data received from the surround view system (12). If the data from the surround view system (12) indicates the presence of an animal, the processing module (14) activates an alert (19).

  • Patent number: 9403224
    Abstract: A combined chop saw and work table includes a carrying case having a cover and a support base removably attached thereto in such a manner that the carrying case is selectively configured between closed and open positions. A chop saw is selectively situated outside and inside of the carrying case when the carrying case is configured at the open and closed positions, respectively. When the carrying case is at the closed position, each of the cover and the support base are at a respective upright orientation. When the carrying case is at the open position, the support base is at the upright orientation and the cover is at an inverted orientation. The carrying case defines a work table when configured to the open position such that the chop saw is contemporaneously exposed above the cover and the support base.

  • Patent number: 9347180
    Abstract: The invention relates to a device for dewatering a fibrous web with a press zone which is formed by a mating element with a curved surface and a permeable press belt which wraps at least partially around the curved surface and has a running side and a contact side contacting a second side of the fibrous web. A permeable carrier belt arranged between the mating element and the fibrous web guides the fibrous web through the press zone. The device is configured so a fluid can flow through the press belt, the fibrous web, and the permeable carrier belt at least in a part region of the press zone. The permeable press belt is configured to generate a pressing pressure in the press zone when a tensile stress of at least 20 kN/m is applied and the contact side is adapted to a quality of the fibrous web produced.

  • Patent number: 8440055
    Abstract: A pressing arrangement including at least one first fabric and second fabric both being permeable. A paper web is disposed between the first fabric and the second fabric. A pressure producing element is in contact with the first fabric. A support surface of a supporting structure is in contact with the second fabric. A differential pressure is provided between the first fabric and the support surface that acts on the first fabric, the paper web, and the second fabric, whereby the paper web is subjected to mechanical pressure and experiences a predetermined hydraulic pressure so as to cause water to be drained from the paper web. The pressing arrangement is structured and arranged to allow air to flow in a direction from the first fabric through the paper web and through the second fabric.

  • Patent number: 8314218
    Abstract: The present invention relates to methods for synthesizing macrolide compounds which are known to have antibacterial activity, and are useful in the therapy of bacterial infections in mammals. More specifically, the invention relates to methods for synthesizing the macrolide antibiotic, gamithromycin utilizing a novel configuration of catalysts, chemical structures, and/or methods. An embodiment of the present invention may include allowing multiple chemical reactions to proceed without the isolation of chemical intermediates. Thus, multiple reactions may occur in one reaction vessel allowing for a considerable decrease in the cycle-time. The present invention also provides a novel method for inhibiting degradation while isolating a structure of a pharmaceutical composition.

  • Patent number: 8303773
    Abstract: A method of producing a tissue paper web in a papermaking machine including the steps of forming the web on a skin, selecting a quality of the web, bypassing a dewatering apparatus, passing the skin and web through a nip and conveying the web to a drying cylinder from the skin. The web is formed in a forming section of the machine from a pulp suspension on the skin. In the selecting step a quality of the web is selected thereby defining a quality selection of absorbency or tear resistance. The bypassing step includes bypassing the dewatering apparatus with the web and selecting a type of the skin dependent upon the quality selection.
