Abstract: In an example method, a mobile device obtains sample data generated by one or more sensors over a period of time, where the one or more sensors are worn by a user. The mobile device determines that the user has fallen based on the sample data, and determines, based on the sample data, a severity of an injury suffered by the user. The mobile device generates one or more notifications based on the determination that the user has fallen and the determined severity of the injury.

Abstract: The present disclosure is related to systems and methods for indoor positioning. The method includes obtaining a first location of a subject at a first time point. The method also includes determining one or more motion parameters associated with the subject at least based on one or more sensors carried by the subject. The method further includes determining, based on the first location of the subject and the one or more motion parameters associated with the subject, a second location of the subject at a second time point after the first time point. The method still further includes adjusting, at least based on surroundings information associated with the subject at the second time point, the second location of the subject to determine a target location of the subject.

Abstract: By a movement amount estimation device, a movement amount estimation method, or a computer-readable non-transitory storage medium storing a movement amount estimation program, a degree of a priority of a combination of each of past satellite data acquired by a receiver at a plurality of past points and current satellite data acquired at a current point, for using the priority for estimating a movement amount is determined, and a relative movement amount from at least one of the plurality of past points to the current point is calculated.

Abstract: Visual-inertial odometry uses visual input from a camera and inertial motion measurements to track the motion of an object. This technique can be applied to surveying urban environments, such as a curb or streetscape, that are impractical to survey with a surveyor's wheel, GPS, or imagery from cars. Making visual-inertial odometry measurements of a curb with a handheld surveying device yields relative measurements from a starting point to an ending point on the curb. These relative measurements can be pinned to an absolute coordinate frame using measurements of gravity made while acquiring the visual-inertial odometry measurements and absolute measurements of the starting and ending points.

Abstract: One or more devices in a data analysis computing system may be configured to receive and analyze acceleration data corresponding to driving data, analyze the acceleration data, and determine driving patterns and associated drivers based on the data. Acceleration data may be collected by one or more mobile devices, such as smartphones, tablet computers, and/or on-board vehicle systems. Drivers associated with driving trips may be identified based on the acceleration data collected by the mobile devices. In some cases, driving patterns may be determined based on the acceleration data before and after stopping points during driving trips, and the driving patterns may be compared to a set of previously stored driving patterns associated with various different drivers.

Abstract: A device and a method for determining a rough component of a latitude or longitude position of a moving craft. The position is reconstructed cyclically by combining the rough component with a corresponding fine component. The device determines the sign of a difference between the fine component for an acquisition cycle and the fine component for a preceding acquisition cycle. The device then computes the rough component corresponding to the given acquisition cycle of the fine component, as a function of the sign of the difference and of the sign and of the value of the speed of the craft. The device and the corresponding method make it possible to extrapolate an unrefreshed rough component as a function of the trend of the fine component and of the sign of the speed of the moving craft to reduce error associated with the computation of the latitude or longitude position.
