Abstract: A vehicle system includes a processor and a memory. The memory stores instructions executable by the processor to identify an area of interest from a plurality of areas on a map, to determine that a detected sound is received in a vehicle audio sensor upon determining that a source of the sound is within the area of interest and not another area in the plurality of areas, and to operate the vehicle based at least in part on the detected sound.

Abstract: The present invention extends to methods, systems, and computer program products for evaluating autonomous vehicle algorithms. Aspects use (e.g., supervised) machine learning techniques to analyze performance of autonomous vehicle algorithms on real world and simulated data. Machine learning techniques can be used to identify scenario features that are more likely to influence algorithm performance. Machine learning techniques can also be used to consolidate insights and automate the generation of relevant test cases over multiple iterations to identify error-prone scenarios.

Abstract: Data from sensors of a vehicle is captured along with data tracking a driver's gaze. The route traveled by the vehicle may also be captured. The driver's gaze is evaluated with respect to the sensor data to determine a feature the driver was focused on. A focus record is created for the feature. Focus records for many drivers may be aggregated to determine a frequency of observation of the feature. A machine learning model may be trained using the focus records to identify a region of interest for a given scenario in order to more quickly identify relevant hazards.

Abstract: Systems, methods, and devices for estimating a shape of an object based on sensor data and determining a presence of a fault or a failure in a perception system. A method of the disclosure includes receiving sensor data from a range sensor and calculating a current shape reconstruction of an object based on the sensor data. The method includes retrieving from memory a prior shape reconstruction of the object based on prior sensor data. The method includes calculating a quality score for the current shape reconstruction by balancing a function of resulted variances of the current shape reconstruction and a similarity between the current shape reconstruction and the prior shape reconstruction.

Abstract: A bladder shell for inflatable balls having a layer of blended synthetic latex and natural rubber latex compounded with an anti-oxidant, an activator, an accelerator, a thickening agent, a wetting agent, and a stabilizer etc. to form a low air permeability and high bounce bladder shell having thickness of between 0.25 mm to 3.0 mm. Also disclosed is a process for the preparation of the bladder shell that includes dipping former in a bath of blended natural rubber latex and synthetic latex.

Abstract: A bladder shell for inflatable balls having at least a pair of layers of compounded synthetic latex and compounded natural rubber latex or at least a layer of blended synthetic latex and natural rubber latex compounded with anti-oxidant, activators, accelerators, thickening and wetting agents, stabilizers etc. to form a low air permeability and high bounce bladder shell having thickness of between 0.25 mm to 3.0 mm.

Abstract: A bladder shell for inflatable balls having at least a pair of layers of compounded synthetic latex and compounded natural rubber latex or at least a layer of blended synthetic latex and natural rubber latex compounded with anti-oxidant, activators, accelerators, thickening and wetting agents, stabilizers etc. to form a low air permeability and high bounce bladder shell having thickness of between 0.25 mm to 3.0 mm. The present invention also defines a process for the preparation of the bladder shell comprising formation of at least a layer of natural rubber latex and a synthetic latex each. The process of the present invention comprises dipping the former in not only a natural rubber latex bath but also in the synthetic latex bath. In an another embodiment, the process comprises dipping the former in the bath comprising blended natural rubber latex and synthetic latex.
