Abstract
The devices and methods described herein are utilized to continuously track unpowered logistics platforms such as semi-trailers and intermodal shipping containers. In some examples, a tracking device harvests the kinetic energy of oscillatory movements of the shipping container to power the tracking device. In some instances, the shipping container is moving on a roadway, railway, or waterway. In other examples, a tracking device harvests the kinetic energy of airflow moving around the shipping container. In some instances, the airflow is caused by movement of the shipping container. In other instances, the airflow may be caused by ambient weather such that air is flowing around a stationary shipping container.
Claims14
A method for tracking a geolocation of a shipping container, the method comprising:
- inducing electrical power from relative movement between at least one magnet and at least one inductor of a tracking device, the relative movement caused by oscillatory movement of a shipping container, wherein the at least one inductor has at least one inductor coil physically coupled to a sleeve, the at least one magnet having at least one rounded surface and being rollable within at least a portion of the sleeve in response to oscillatory movement of the shipping container;
- determining geolocation information of the shipping container;
- logging a set of the determined geolocation information of the shipping container;
- transmitting at least a portion of the set of determined geolocation information to a server;
- storing energy induced by the inductor during a first time period;
- and
- providing the stored energy to the tracking device during a second time period.
A method for tracking a geolocation of a shipping container, the method comprising:
- inducing electrical power from relative movement between at least one magnet and at least one inductor of a tracking device, the relative movement caused by oscillatory movement of a shipping container, wherein the at least one magnet is a magnetically charged ball and the at least one inductor is integrated into, or disposed adjacent to, a concave surface in which the magnetically charged ball is movably disposed, the magnetically charged ball movable relative to the inductor in response to oscillatory movement of the shipping container;
- determining geolocation information of the shipping container;
- logging a set of the determined geolocation information of the shipping container;
- transmitting at least a portion of the set of determined geolocation information to a server;
- storing energy induced by the inductor during a first time period;
- and
- providing the stored energy to the tracking device during a second time period.
A method for tracking a geolocation of a shipping container, the method comprising:
- spinning up a flywheel of a tracking device such that the flywheel stores energy during a first time period and provides the stored energy to the tracking device during a second time period, wherein the flywheel is spun up by a turbine disposed within a recess formed within an external surface of a shipping container such that airflow around the shipping container causes the turbine to spin;
- determining geolocation information of the shipping container;
- logging a set of the determined geolocation information of the shipping container;
- and
- transmitting at least a portion of the set of determined geolocation information to a server.
