A hail strike recording device is operable to provide quantifiable information about a hail storm event experienced by a roof. The recording device is operable to be installed on a roof and includes a panel component and a mounting assembly. The panel component presents a hail impact zone to sense one or more hail strikes, with the recording device operable to provide recorded data associated with the sensed one or more hail strikes.

Systems and methods are for determining and/or forecasting local atmospheric stability and/or turbulence. This information can be used to inform decisions regarding crop spraying, such as whether the atmospheric conditions are sufficiently turbulent to avoid airborne spray fines drifting in an undesirable manner. For example, a spray drift hazard alert system can include a data logger. The data logger is configured to: receive local meteorological observation data from one or more sensors at a location, analyze the data to determine a local vertical turbulence characteristic indicative of a current level of vertical turbulence at the location, compare the vertical turbulence characteristic with a predetermined threshold of the vertical turbulence characteristic, and transmit information to a client device indicating whether local meteorological conditions are suitable for crop spraying based on the comparison between the vertical turbulence characteristic and the predetermined threshold.

In a method for training temporal precipitation interpolation models, the method may include receiving an initial image, a first intermediate image, and a final image, computing a first preliminary forward optical flow vector field from the initial image, and a first preliminary backward optical flow vector field, computing a first refined forward optical flow vector field and a first refined backward optical flow vector field using a terrain factor, among other things, and computing backpropagation losses to train neural networks by comparing the first intermediate image to an interpolated frame calculated using the first refined forward optical flow vector field and the first refined backward optical flow vector field.

A method for acquiring road data onboard a vehicle, the road data associated with a segment of road is provided. The method obtains, via vehicle onboard sensors, sensor data associated with current weather conditions, current road conditions, and a physical road state; determines whether the current weather conditions indicate existence of severe weather, whether the current road conditions indicate potential slip, and whether the physical road state indicates one or more road anomalies; generates a road data result, based on existence of severe weather, potential slip, and one or more road anomalies; and transmits the road data result, via a vehicle onboard telematics unit.

Example implementations may relate to selection between a first mode and a second mode. The first mode may involve (i) directing an aerial vehicle (e.g., in an aerial network including a plurality of aerial vehicles) to navigate to each of a plurality of altitudes and (ii) determining respective wind-related data at each respective altitude. Whereas, the second mode may involve (i) selecting at least one altitude based on the determined wind-related data and (ii) directing the aerial vehicle to reposition to the at least one selected altitude. As such, a control system may determine flight data for the aerial vehicle. Based on the flight data, the control system may make a selection between the first mode and the second mode. And based on the selection, the control system may then operate the aerial vehicle according to the first mode or may operate the aerial vehicle according to the second mode.

An automated roadway marker system that illuminates and provides warning and lane demarcation under poor visibility conditions utilizing IR beam-break transceivers where no deployment considerations need to be made for the first in a sequence, because each marker operationally establishes its linkage condition in an intermittently activated asynchronous pseudo-network. The devices are designed for extremely low power consumption, so that solar energy can be utilized as a power source. The markers can additionally be linked through radio frequency signals, and to provide a warning to mobile and stationary radio frequency receivers. Additionally, the markers can be illuminated via transmissions from mobile and stationary transmitters.
