    Abstract: A three-dimensional map of an environment with buildings is used to computationally predict locations and times of global navigation satellite system (GNSS) blockages. For example, in urban environments some of the GNSS satellites are occluded by buildings. These blockages can be modeled. A computing system can make a map showing which satellites are or are not visible as a function both of location and time. The map can be used by a mobile GNSS receiver to determine which satellites to use or whether to use a backup system for navigation. The system can determine when a given satellite will enter or leave a GNSS receiver view during a route. The map can be stored in the GNSS receiver (or a host of the GNSS) or can be stored by a network service. This mapping can be used to predict multi-path effects of a satellite transmission at a location.

    Abstract: Described embodiments include a system and method. A digital imaging device is configured to capture images of a region of a contact between a wheel of a terrestrial vehicle and a surface (“contact region”). A correlator is configured to correlate a first digital image of the contact region captured at a first time with a second digital image of the contact region captured at a second time. A kinematics circuit determines an incremental slide or slip of the wheel relative to the surface. A fraction status circuit combines at least two instances of the incremental slide or slip into data indicative of a slide or slip by the terrestrial vehicle relative to the surface. A communications circuit outputs an electronic signal indicative of the data indicative of a slide or slip by the terrestrial vehicle.

    Abstract: Described embodiments include a system, apparatus, and method. A system includes an array of at least two groups of at least two artificially structured electromagnetic unit cells. Each group includes a controllable amplifier responsive to a B1 localization control signal and configured to amplify a received pulse of radiofrequency electromagnetic waves. Each group includes an electromagnetic wave conducting structure configured to deliver an amplified pulse of radiofrequency electromagnetic waves to the at least two artificially structured electromagnetic unit cells. The at least two artificially structured electromagnetic unit cells are configured to transform the incident amplified pulse into a pulse of radiofrequency magnetic field B1 orientated transverse to a segment of the z-axis. A control circuit selects an arbitrary examination segment transverse to the z-axis responsive to data indicative of a transverse slice selected for examination, and generates the B1 localization control signal defining an amplification state assigned to each group.
