摘要： Association algorithms of newly-detected lane boundaries to lane boundaries can be made more robust through the use of generated or “dummy” states. Different types of dummy states can be used to identify outlier/erroneous detections and/or new, legitimate lane boundaries. Therefore, depending on a type of dummy state a newly-detected lane boundary is associated with, the newly-detected lane boundary can be ignored, or the associated dummy state can be added to the lane boundary states of the filter.

摘要： A method for position determination based on carrier-phase measurements is disclosed. The method comprises receiving one or more downlink signals transmitted from a base station (BS) during a downlink period, wherein the downlink signals are modulated using a downlink carrier wave, measuring, during the downlink period, a first carrier phase associated with the downlink carrier wave, estimating, during an uplink period subsequent to the downlink period, an integer ambiguity (IA) change, and measuring, during a later downlink period subsequent to the uplink period, a second carrier phase based on the resolved first carrier phase and the estimated IA change.

摘要： System, methods, and apparatus are described for transmitting encoded bits over a bus by conditionally embedding dynamically shielded information. In an example, the apparatus transmits a first group of encoded bits over a bus, generates a second group of encoded bits to be transmitted over the bus, where a first subset of the second group of encoded bits are encoded to avoid crosstalk-inducing bit transitions on adjacent lines of the bus, and configures one or more encoded bits of a second subset of the second group of encoded bits to ensure that the second group of encoded bits includes parity information and/or clock information, while further ensuring that crosstalk-inducing bit transitions in the second group of encoded bits are avoided.

摘要： System, methods, and apparatus are described that facilitate transmission/reception of data over a multi-line parallel bus. In an example, the apparatus transmits data bits over a parallel bus includes determining from a prior bus state, a plurality of free wires in the bus for a current bus state, where each free wire satisfies a crosstalk-avoidance constraint in the current bus state for all values of a bit transmitted on the free wire. The apparatus may encode a plurality of data bits using a crosstalk avoidance encoder to obtain a CAC-encoded word, compute an error detection or correction code for the CAC-encoded word, assign bits of the error detection or correction code to the plurality of free wires for transmission during the current bus state, and assign the CAC-encoded word to unassigned wires of the bus for transmission during the current bus state.

摘要： Various embodiments disclose a device with one or more processors which may be configured to translate a radio detection and ranging (RADAR) reference depth map into depth information in at least one image plane of at least one camera, to form a three-dimensional RADAR depth image. The 3D RADAR depth image includes a depth estimate of each pixel. The one or more processors may also be configured to initialize a RADAR-aided visual inertial odometer based on the depth estimates from the RADAR reference depth image to track the device position.

摘要： Various embodiments disclose a device with one or more processors which may be configured to translate a RADAR velocity map in at least one image plane of at least one camera, to form a three-dimensional RADAR velocity image. The 3D RADAR velocity image includes a relative velocity of each pixel in the one or more images, and the relative velocity of each pixel is based on a RADAR velocity estimate in the three-dimensional RADAR velocity map. The one or more processors may be configured to determine whether visual features correspond to a moving object based on the relative velocity of each pixel determined, and may be configured to remove the visual features that correspond to a moving object, prior to providing them as an input into a state updater, in a RADAR-aided visual inertial odometer.

摘要： Disclosed embodiments pertain to a method on a UE may comprise determining a first absolute position of the UE at a first time based on GNSS measurements from a set of satellites. At a second time subsequent to the first time, the UE may determine a first estimate of displacement of the UE relative to the first absolute position using non-GNSS measurements. Further, at the second time, the UE may also determine a second estimate of displacement relative to the first absolute position and/or a second absolute position of the UE based, in part, on: the GNSS carrier phase measurements at the first time from the set of satellites, and GNSS carrier phase measurements at the second time from a subset comprising two or more satellites of the set of satellites, and the first estimate of displacement of the UE.

摘要： Techniques provided herein are directed toward virtually extending an updated set of output positions of a mobile device determined by a VIO by combining a current set of VIO output positions with one or more previous sets of VIO output positions in such a way that ensure all outputs positions among the various combined sets of output positions are consistent. The combined sets can be used for accurate position determination of the mobile device. Moreover, the position determination further may be based on GNSS measurements.
