US 11,601,783 B2 · Detection of a physical collision between two client devices in a location sharing system

Abstract

The invention provides methods, systems, and devices for detecting a physical collision between two client devices based on sensor data. A server computer receives a first collision signature from a first client device, and a second collision signature from a second client device. Based on determining that a correlation of the first collision signature and the second collision signature does not achieve a detection threshold, the server computer lowers, for a limited period of time, the detection threshold. If the server computer receives, within the limited period of time, a third collision signature from the first client device, and a fourth collision signature from the second client device, and determines that a correlation of the third collision signature and the fourth collision signature achieves the lowered detection threshold, the server computer detects a collision between the first and second client devices.

Dependent claims

A method comprising:

receiving, at a server computer, a first collision signature from a first client device, and a second collision signature from a second client device;
determining that a first timespan between a timestamp of the first collision signature and a timestamp of the second collision signature is below a time threshold;
increasing, based on determining that the first timespan is below the time threshold, the time threshold for a limited period of time;
receiving, at the server computer and within the limited period of time, a third collision signature from the first client device, and a fourth collision signature from the second client device;
determining that a second timespan between a timestamp of the third collision signature and a timestamp of the fourth collision signature meets the time threshold;
and
detecting, based on determining that the second timespan meets the time threshold, a collision associated with the first and second client devices.
