US Patent:

20210039669, Feb 11, 2021

Filed:

Feb 4, 2019

Appl. No.:

16/965701

Inventors:

- St. Paul MN, US
John A. Wheatley - Stillwater MN, US
James B. Snyder - Minneapolis MN, US
Kenneth L. Smith - White Bear Lake MN, US

International Classification:

B60W 50/14
G06K 9/00

Abstract:

In some examples, a method of validating operation of a vehicle, includes determining, by the vehicle, a first version of a vehicle operating parameter via a vehicle instrument employed in a first measurement approach; calculating, by the vehicle, a second version of the vehicle operating parameter based on information indicated by two or more pathway articles associated with a vehicle pathway; determining, by the vehicle, if the first version of the vehicle operating parameter is approximately equal to the second version of the vehicle operating parameter; if the first version of the vehicle operating parameter is approximately equal to the second version of the vehicle operating parameter, validating the first measurement approach; and if the first version of the vehicle operating parameter is not approximately equal to the second version of the vehicle operating parameter, performing, by the vehicle, one or more actions.

Abstract:

In some examples, a computing device includes one or more computer processors, a communication device, and a memory comprising instructions that cause the one or more computer processors to: receive, using the communication device and from a set of vehicles, different sets of infrastructure data for a particular infrastructure article that is proximate to each respective vehicle of the set of vehicles, wherein each respective vehicle in the set of vehicles comprises at least one infrastructure sensor that generates infrastructure data descriptive of infrastructure articles that are proximate to the respective vehicle; determine, based at least in part on the different sets of infrastructure data for the particular infrastructure article from each respective vehicle of the set of vehicles, a quality metric for the infrastructure article; and perform at least one operation based at least in part on the quality metric for the infrastructure article.

International Classification:

G06K 7/14
G06K 19/06

Abstract:

In some examples, an article includes a substrate, the substrate including a physical surface; a hierarchy of parent and child optical element sets embodied on the physical surface, wherein a first encoded value represented by the parent optical element set is based at least in part on a visual appearance of a particular optical element in the child optical element set, and a second encoded value represented by the particular optical element is based at least in part on the visual appearance, the first and second encoded values being different, and the second encoded value not being decodable from a distance greater than a threshold distance, the first encoded value being decodable from the distance greater than the threshold distance.

International Classification:

G06K 19/06
G06K 7/14

Abstract:

In some examples, an article includes a substrate and a plurality of optical element sets embodied on the substrate, wherein each optical element set includes a plurality of optical elements, wherein each respective optical element represents an encoded value in a set of encoded values, wherein the set of encoded values are differentiable based on visual differentiability of the respective optical elements, wherein each respective optical element set represents at least a portion of a message or error correction data to decode the message if one or more of the plurality of optical element sets are visually occluded, and wherein the optical element sets for the message and error correction data are spatially configured at the physical surface in a matrix such that the message is decodable from the substrate without optical elements positioned within at least one complete edge of the matrix that is visually occluded.
