20130042856 | Solar Energy Positioning System Using Cable Drives and Two Axis Pivot - A system for positioning a heliostat mirror or a solar collector includes a support structure, a pivot mechanism adapted to pivot the heliostat mirror or solar collector about a first generally horizontal axis and about a second axis generally perpendicular to the first axis, the pivot mechanism is attached to a rear side of the heliostat mirror or solar collector and attached to the support structure. The system also includes a first cable drive actuator having a first motor, driving a first cable spool, and a first cable attached at a proximal end to the first cable spool and attached at a distal end to the heliostat mirror or solar collector, and a second cable drive actuator having a second motor driving a second cable spool, and a second cable attached at a proximal end to the second cable spool and attached to the heliostat mirror or solar collector. | 02-21-2013 |

20130000692 | METHOD OF MANUFACTURING HELIOSTAT MIRROR WITH SUPPORTING TILE ELEMENTS - A mirror module may include a front plate, a rear plate and a support structure between the front plate and the rear plate. The support structure includes a carrier mesh and multiple tile elements secured to the carrier mesh. The carrier mesh is prefabricated to mount tile elements. During the fabrication of the mirror module, the carrier mesh with tile elements is secured onto the front or rear plate and then secured to the other remaining plate. The mirror module is shaped by assembling the plates and the carrier mesh on a shaping tool or placing the assembled mirror module on a shaping tool. The tile elements may be made of the same material as the front plate or the rear plate to reduce stress on the front plate or rear plate due to temperature fluctuation. | 01-03-2013 |
20130003205 | HELIOSTAT MIRROR WITH SUPPORTING RIB STRUCTURE - A mirror module including one or more rib elements made of the same materials as a rear plate and/or front plate. The rib elements are placed between the rear glass plate and the front glass plate to afford rigidity to the mirror module. Since the rib elements are made of the same materials as the rear plate and/or front plate, the rib elements have the same or similar coefficients of thermal expansion as the rear plate or the front plate. Consequently, when the mirror module is subject to temperature fluctuation, the rib elements exert less stress on the glass plates compared to structure elements made of the materials different from the rear or front glass plate. The rib elements may also be integrated with the rear plate to simplify the process for manufacturing the mirror module. | 01-03-2013 |

20130000693 | Solar Positioning System and Method - An apparatus for positioning an object, for example, a solar energy capture device, can include a frame, the object, a joint, and at least two linear actuators. The joint connects the object to the frame and allows the object to rotate relative to the frame. The first and second linear actuators are coupled to the object. When the first and second actuators are actuated in combination, the object rotates about a pitch axis. When the first and second actuators are actuated differentially, the object rotates about a roll axis. | 01-03-2013 |

20100114431 | Method for Controlling Vehicle Dynamics - A method for controlling vehicle dynamics includes acquiring steering torque data indicative of forces acting on at least one tire of a vehicle and acquiring image data by capturing images of an area outside the vehicle. The friction coefficient between a tire of the vehicle and a road surface is determined as a function of vehicle data including at least the steering torque data. The lateral velocity of the vehicle is determined as a function of vehicle data including the steering torque data and/or the image data. A vehicle dynamics control is performed as a function of the lateral velocity and the friction coefficient. | 05-06-2010 |
20100145575 | Method for Providing a Lanekeeping Assistance Based on Modifying Mechanical Sources of Steering Torques - A method for providing a lanekeeping assistance for a vehicle includes determining road lane characteristics such as a road lane curvature. A vehicle velocity and a vehicle position with respect to a road lane are also determined. A desired steering angle is determined as a function of at least the road lane characteristics. A lanekeeping torque acting on the steering system of the vehicle in order to keep the vehicle on a desired path is determined as a function of at least the desired steering angle. The lanekeeping torque is generated by modifying at least one mechanical steering torque such as a jacking torque, an aligning torque, an inertia torque and a damping torque. | 06-10-2010 |

20160054735 | VEHICLE PLATOONING SYSTEMS AND METHODS - Systems and methods for coordinating and controlling vehicles, for example heavy trucks, to follow closely behind each other, or linking, in a convenient, safe manner and thus to save significant amounts of fuel while increasing safety. In an embodiment, on-board controllers in each vehicle interact with vehicular sensors to monitor and control, for example, relative distance, relative acceleration/deceleration, and speed. Additional safety features in at least some embodiments include providing each driver with one or more visual displays of forward and rearward looking cameras. Long-range communications are provided for coordinating vehicles for linking, and for communicating analytics to fleet managers or others. | 02-25-2016 |

20120140224 | RETROREFLECTORS FOR REMOTE DETECTION - A detection system includes a retroreflector and a layer of material over the retroreflector, the material being subject to change in transmission with respect to an optical property of radiation, e.g. wavelength or polarization, with exposure to a phenomenon. The retroreflector and layer are illuminated from a radiation source of multiple aspects of the optical property. A sensor senses radiation retroreflected back through the layer. The retroreflector may, for example, be an array of or individual prisms or an array of or individual cat's eye microspheres. The layer of material above the retroreflector can include a colorimetric dye. In an embodiment, the retroreflector and layer are on the surface of a carrier that moves through a medium, e.g. a projectile or vehicle moving through the air. In a method of detecting a phenomenon, retroreflective elements are distributed in an array, as in the atmosphere or across a region of ground. | 06-07-2012 |
