    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.

    Abstract: In some examples, a method includes selecting, by a coding computing device, a particular identifier from a set of identifiers generated by an identifier allocation authority, wherein the set of identifiers are included within a global set of identifiers maintained by the identifier allocation authority; coding, by the coding computing device, the particular identifier from the set of identifiers into an optical element set that represents an optical code comprising a plurality of finder optical elements arranged in a pattern to localize the optical code within an image, a plurality of context optical elements representing context information, and a plurality of content optical elements representing content information; and generating a visual output of the optical code that is decodable to the particular identifier which, in combination with at least one other parameter associated with the optical element set, comprises a globally unique identifier in a set of globally unique identifiers.

    Abstract: In some examples, a sign maintenance system includes a traffic management control system; a plurality of road side equipment; and an infrastructure management service provider; wherein a sign maintenance application determines information needed for sign maintenance planning and transmits a probe management request to the traffic management control system requesting the information; wherein the traffic management control system transmits a probe management message to road side equipment in response to the probe management request, receives one or more messages received from connected vehicles, the messages reflecting sensor information captured by sensors of the connected vehicles, and transmits, to the infrastructure management service provider, the information received from the vehicle messages, and wherein the sign maintenance application in the infrastructure maintenance service provider schedules sign maintenance based on the information received from the connected vehicles.

    Abstract: A device for recognizing activity of an object. The device comprises a housing configured to be attached to the object and a processing unit disposed in the housing comprising a processor and a movement sensor. The movement sensor measures a signal related to movement of the object during a time window. The processor assigns at least one preliminary activity label to the time window based on at least one numerical descriptor computed from the signal. The processor then determines whether to perform additional analysis dependent upon at least the preliminary activity label. The processor then assigns a final activity label to the time window.

    Abstract translation: 用于识别对象的活动的设备。 该装置包括构造成附接到物体的壳体和设置在壳体中的处理单元，其包括处理器和运动传感器。 移动传感器在时间窗口中测量与物体的移动有关的信号。 基于从该信号计算出的至少一个数字描述符，处理器将至少一个初步活动标签分配给时间窗口。 然后，处理器确定是否依赖于至少初步活动标签来执行附加分析。 处理器然后将最后的活动标签分配给时间窗口。
