Abstract: A method for enhancing the sensing capabilities of an autonomous vehicle. The method includes extending an extension assembly mounted to the autonomous vehicle to position one or more sensors above the autonomous vehicle and receiving, from the one or more sensors, at least one sensor signal representing one or more vehicle environment conditions surrounding the autonomous vehicle. The method also includes generating a vehicle state for the autonomous vehicle based at least on a location of the autonomous vehicle, the vehicle state comprising the one or more vehicle environment conditions.

Abstract: Detection of trailer dynamic parameters is provided. A vehicle can receive a geometry of a plurality of points of support disposed along a longitudinal axis of the trailer. The vehicle can determine a center of mass of the trailer based on the plurality of points of support and weights bearing down thereupon. The vehicle can bound or otherwise determine, based on the geometry of the plurality of points of support and the center of mass, a moment of inertia of the trailer about at least one of the plurality of points of support. The vehicle can perform a navigational action based on the moment of inertia or center of mass.

Abstract: Aspects of this technical solution can include determining, by one or more processors of a liquid collection system and based on respective amounts of liquid detected by a plurality of sensors and a velocity of a vehicle, a direction of movement of the liquid. The plurality of sensors can each be associated with respective ones of a plurality of receptacles. The plurality of sensors can be configured to detect respective amounts of liquid collected by respective openings of each of the plurality of receptacles associated with corresponding directions of movement of a liquid. The plurality of receptacles can be configured to collect at least a portion of the liquid via the respective openings.

Abstract: An autonomous vehicle comprises a sensor and one or more processors. The processors can be configured to monitor, using the sensor, a surface of a road while the autonomous vehicle is driving on the road; detect a numerical identification of a tracking tag embedded underneath a surface of the road based on data collected from the sensor during the monitoring of the surface; query a database using the numerical identification of the tracking tag, the database comprising navigational information corresponding to different numerical identifications of tracking tags; identify first navigational information from the database that corresponds to the detected numerical identification of the tracking tag embedded underneath the surface of the road; determine a navigational action based on the first navigational information; and operate the autonomous vehicle according to the navigational action.

Abstract: An autonomous vehicle comprises a sensor, a plurality of paint dispensers, and one or more processors. The processors can be configured to collect, using the sensor, data regarding an environment surrounding the autonomous vehicle as the autonomous vehicle is moving on a surface; detect an event in the environment surrounding the autonomous vehicle from the collected data; determine an event type of the event based on the collected data; select a paint dispenser from the plurality of paint dispensers based on the determined event type; and automatically dispense paint from the selected paint dispenser onto the surface.

Abstract: A sensor integrated circuit includes a main processing channel that responds to an input signal by generating a first processed signal from the input signal. Also included is a diagnostic processing channel that responds to the input signal by generating a second processed signal from the input signal. The main processing channel has a first response to disturbances and the diagnostic processing channel has a second response to disturbances that is slower than the first response of the main processing channel. A checker circuit in the sensor integrated circuit detects faults in the sensor IC and generates a fault signal when the first processed signal and the second processed signal differ from each other by more than a threshold amount.

Abstract: Volume changes in a brain, brain ventricle, or hippocampus are quantitatively extracted from a comparison of 3D before and after images using an algorithm that distorts a triangulated surface of the before image to produce the surface of the after image and calculates the volume change from the area change.
