Abstract: This invention provides a tilt angle adjustable combined rat-proof device, relating to the technical field of rat-proof devices. A rat-proof device includes a rat-proof plate body, a fixing mechanism and an adjusting mechanism, wherein the rat-proof plate body is inserted into the fixing mechanism so that the rat-proof plate body is able to be clamped, and an upper end of the fixing mechanism is clamped into the adjusting mechanism and is able to slide along the adjusting mechanism so as to drive the rat-proof plate body to move, thereby realizing adjustment of the tilt angle of rat-proof plate body. The device can adjust the tilt angle based on the user's actual requirements, therefore adapting to the use environment, and it is also extremely convenient in the process of transportation, disassembly and installation.

Abstract: A computer-implemented method of detecting distracted driving comprises: determining, by one or more processors, a primary preview region (PPR) in a representation of an environment; determining, by the one or more processors, a gaze point for a driver based on a sequence of images of the driver; determining, by the one or more processors, that the gaze point is outside of the PPR; based on the determined gaze point being outside of the PPR, decreasing, by the one or more processors, an attention level for the PPR; based on the attention level for the PPR, generating, by the one or more processors, an alert.

Abstract: A system for determining distress of a driver of a vehicle is provided, comprising a plurality of sensors, including interior vehicle image sensors, an interior vehicle audio sensor, vehicle data sensors, and Global Positioning System (GPS) data sensors. The system also includes one or more processors configured to receive inputs from the plurality of sensors, and process the received inputs to obtain a driver heat change estimate, a driver expression estimate, a driver gesture estimate, an on-board diagnostics (OBD) estimate, and a GPS estimate. The one or more processors are further configured to store the estimates in a memory, use the stored estimates to generate deviation scores for each of the estimates, execute a machine learning algorithm to classify driver behavior as normal or impaired based on the deviation scores, and generate a warning based on the classification indicating impaired driver behavior.
