The patent’s inventors are Menon, Sunish Shreenarayan (Normal, IL); Dosher, David James (Fitchburg, WI); Christensen, Scott Thomas (Bloomington, IL).

This patent was filed on April 9, 2019 and was published online on November 23, 2020.

From the background information supplied by the inventors, news correspondents obtained the following quote: “The background description provided herein is for the purpose of generally presenting the context of the disclosure. Work of the presently named inventors, to the extent it is described in this background section, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure.

“Many companies employ vehicle monitoring systems for a variety of purposes, including determination of insurance risk and/or premiums. These systems may monitor many vehicle attributes, such as location, speed, acceleration/deceleration, etc. The monitoring devices are integrated with the vehicle or plugged into the vehicle systems. Many of these monitoring systems require expert installation into the vehicle and further require the user to periodically withdraw the monitoring device to download the trip data.”

Supplementing the background information on this patent, NewsRx reporters also obtained the inventors’ summary information for this patent: “This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.

“In one embodiment, a computer implemented method for determining a primary movement window from a vehicle trip is provided. The method may include placing a client computing device in a vehicle, wherein the client computing device is free to move with respect to movement of the vehicle; receiving, via a computer network, a plurality of telematics data originating from the client computing device placed in the vehicle, wherein the client computing device includes an accelerometer; summarizing, by one or more processors, the plurality of telematics data at a specified sample rate; converting, by one or more processors, the plurality of telematics data from a time domain to a spectral domain; selecting, by the one or more processors, one or more data points from the converted telematics data; determining, by the one or more processors, that a total spectral power of the selected data points meets a threshold value; and/or identifying, by the one or more processors, a first primary movement window including the selected data points if the total spectral power of the selected data points does not meet the threshold value, wherein the identified first primary movement window is indicative of the accelerometer being static with respect to the vehicle and a total spectral power of the selected data points that meets the threshold value is indicative of the accelerometer moving with respect to the vehicle while in the vehicle.”

The claims supplied by the inventors are:

“2. The method of claim 1, further comprising: identifying, by the one or more processors, a diagonal and an off-diagonal data point of a total spectral power matrix from the telematics data.

“3. The method of claim 2, further comprising: comparing, by the one or more processors, the diagonal and the off-diagonal data points with a threshold value; and determining, by the one or more processors, whether at least one of the diagonal or the off-diagonal data points is above the threshold value.

“4. The method of claim 3 further comprising: determining, by the one or more processors, whether at least one of the diagonal or the off-diagonal data points are below the threshold value.
