Abstract: Combination reactive-proactive controllers and their use are described herein. In a first mode of operation, such controllers may rely simultaneously both a priori information about a road surface ahead of the vehicle obtained from a data base and real time information collected by one or more on-board sensors. Alternatively, in a second mode, such controllers may rely only on real time information collected by one or more on-board sensors. Systems controlled by such controllers may include, but are not limited to, active suspension actuators.

Abstract: Methods and systems are described for accurately determining the location of a vehicle traveling along a road. Methods include first locating the approximate position of a vehicle using techniques such as GNSS or dead reckoning from a know location, and then refining the position of the vehicle using terrain-based localization. This type of localization includes the use of the temporal and spatial variation of magnitude of the correlation between a current road surface profile, obtained while traveling along a road, and previously obtained reference profiles of the same road.

Abstract: Methods and systems related to determining the ordering and/or positioning of travel lanes on a road segment are disclosed. In some embodiments, this may include obtaining and clustering road surface profiles associated with a road segment using, for example, a degree of similarity or other appropriate metric. A lateral offset or position of the clustered profiles may be used in determining the lane ordering and/or position. The resulting lane specific information may be used to determine a travel lane for a vehicle by comparing a current road-profile obtained from the vehicle and the road profile information associated with the different lanes. In other embodiments, a method and/or system for augmenting a global navigation satellite system (GNSS) signal may include using a raw GNSS signal and a GNSS location associated with terrain-based data to determine a lateral offset for use in determining a corrected GNSS location of the vehicle.

Abstract: A method includes simulating diffraction in a transmission geometry of relativistic electron bunches from a crystallographic structure of a crystal thereby simulating diffraction of the relativistic electron bunches into a plurality of Bragg peaks. The method includes selecting a range of angles between a direction of propagation of the relativistic electron bunches and a normal direction of crystal including an angle at which a diffraction portion is maximized. The method includes sequentially accelerating a plurality of physical electron bunches to relativistic energies toward a physical crystal having the crystallographic structure and diffracting the plurality of physical electron bunches off the physical crystal at different angles and measuring the diffraction portion into the respective Bragg peak at the different angles. The method includes selecting a final angle based on the measured diffraction portion into the respective Bragg peak at the different angles and generating a pulse of light.

Abstract: A method includes accelerating an electron bunch along a direction of propagation to a relativistic energy and partitioning the electron bunch by transmitting the electron bunch through a grating at the relativistic energy. The grating includes a plurality of alternating narrow portions and wide portions. The narrow portions have a first thickness in a direction substantially parallel to the direction of propagation of the electron bunch, and the wide portions have a second thickness in the direction substantially parallel to the direction of propagation of the electron bunch. The second thickness is greater than the first thickness. The method also includes generating a pulse of light using the partitioned electron bunch.

Abstract: Some embodiments of the present disclosure provide a method that includes colliding a laser with an electron beam to produce backscattered x-rays while the electron beam is traversing a circular arc. This backscattering process is inverse Compton scattering (ICS). ICS x-rays are emitted in the same direction as the electrons. Because this ICS direction is changing as a function of time, the position of the x-ray beam on a detector will change depending on the timing of electron/laser collision. This position change is easily detected and converted to a timing measurement sensitive at the femtosecond scale, converting a very difficult timing measurement of laser pulse, electron pulse, and x-ray pulse synchronization into a simple and robust position measurement.

Abstract: Methods are provided for proactively controlling a component of a system. The system may comprise a vehicle and the component may comprise a suspension of the vehicle. According to various aspects, methods may include obtaining information regarding a travel surface along a travel path that the system will travel at a future time and, based on the information regarding the travel surface, controlling the component of the system to traverse the travel surface. Controlling the component based on the information regarding the travel surface may comprise comparing the information regarding the travel surface to information regarding at least one physical constraint of the system and/or comparing frequency content of the information regarding the travel surface to a threshold frequency. Proactive control methods may provide improved response to disturbances and improved tracking and isolation because a suspension may be controlled with reduced or substantially zero delay.
