摘要： An apparatus for locating an object of interest using offset. The object may be a mobile platform, or portion of same, associated with a vehicle, or a pavement segment or feature of or on a pavement segment on which the mobile platform is located. The vehicle includes first and second fixed points having a known offset from each other. An image sensor whose field of view includes the second fixed point and a segment of the pavement surface provides image data which is used with the known offset to calculate the precise location of the object of interest.

摘要： A device and method of use for the calibration of a detector. The calibration device includes a first source configured to produce first electromagnetic energy EMR. A first diffuser is connected to the first source and is configured to accept the first EMR and provide a first diffused portion of the first EMR. An integrating sphere defines an interior and is optically connected to the first diffuser, and is configured to accept the first diffused portion from the first diffuser into the interior. An exit port connected to the integrating sphere is configured to pass at least a portion of electromagnetic energy. A thermal mechanism is configured to adjust and maintain the temperature of at least the first source. The integrating sphere is configured to pass only a second portion of the first diffused portion of the first EMR from the first diffuser to the exit port. In another embodiment, the calibration device has an arm, an actuator, and a module. The module supports at least a first source that emits electromagnetic energy, a thermal mechanism, and a controller. The actuator is configured to move the arm and module to a calibration position enabling the first source to be within the line of sight of an external detector, while the controller is configured to control the thermal mechanism enabling precise temperature regulation of the source and therefore the regulation of the emitted electromagnetic energy. When the device is not in the calibration position, the actuator is configured to move the arm and module to a stowed position, protecting the device from ambient electromagnetic radiation and harm.

摘要： A method for mapping distribution of chemical compounds in soil is described herein including inserting a probe into the soil at multiple locations, obtaining spectroscopic data regarding the soil, sampling a core of soil adjacent to the probe locations, dividing the core into multiple depth increments, analyzing the core samples, matching each core sample with a corresponding depth increment of the probe insertions, obtaining data from the probe insertions, dividing the probe insertion data into training, validation, and test categories, resampling spectral variables from the probe insertion data to a wavelength interval longer than a native wavelength interval of an associated spectrometer, normalizing the probe insertion data on a spectrum by spectrum basis, utilizing a machine learning normalization algorithm, standardizing the spectral variables to a common scale by removing a mean and scaling to unit variance, and choosing a model utilizing the test set.

摘要： Aspects presented herein may enable a UE to reduce sensor initialization time for one or more sensors that are to be used for DR positioning during a GNSS signal outage. In one aspect, a UE initiates a first positioning engine based on an availability of a GNSS signal, where the first positioning engine measures a relative position of the UE without ambiguity processing. The UE calibrates at least one IMU sensor based on the relative position of the UE measured by the first positioning engine. The UE performs a positioning calculation of the UE via the at least one IMU sensor in response to the GNSS signal being unavailable.

摘要： A system is disclosed for determining a physical metric such as position. The system comprises a local signal generator (8) configured to provide a local signal and a receiver (4) configured to receive a signal having properties corresponding to those in a signal transmitted by a trusted remote source. An inertial measurement unit (12) is configured to provide a measured or assumed movement of the receiver. A correlator (6) is configured to provide a correlation signal by correlating the local signal with the received signal. A motion compensation unit (14) is configured to provide motion compensation of at least one of the local signal, the received signal, and the correlation signal based on the measured or assumed movement. A signal analysis unit (16) is configured to determine whether the received signal includes a component received in a direction that is different to a line-of-sight direction between the receiver and the trusted remote source, wherein the determination is based on the correlation signal. Finally, a metric determination unit or positioning unit (20) is configured to determine a physical metric associated with the receiver, such as its position, based on the determination made by the signal analysis unit (16).

摘要： A system measures tracking ability of a service animal using a location sensor to generate location data and a measurement unit measuring auxiliary data related to movement of the animal while tracking a known path. A computer calculates a rank metric representing a measure of similarity between animal location data from the location sensor and stored target data defining the known path. The computer also calculates an animal signature representative of a relationship between the auxiliary data and the rank metric for different instantaneous values of the rank metric. When tracking an unknown path, a confidence metric is calculated based on the animal signature and the auxiliary data collected while tracking such that the confidence metric represents a quantitative measure of the ability of the service animal to track the unknown path.
