Benefits of technology

This patent describes a device called a multi-interface transponder (MIT) that can determine its location and communicate with a server to update its location. The MIT device can detect events and transition to a different power state based on the event. It can also enter a low power mode and receive a wake-up signal from a neighboring device to transition to a higher power mode and transmit beacons to help locate the device. The MIT device can use different radios for different purposes and can detect transportation modes and congestion to adjust its beacon transmission. Overall, this technology allows for improved location tracking and communication with a server.

Problems solved by technology

Traditional positional tags (or tracking devices) and corresponding systems typically suffer from one or more disadvantages.
For example, communicating with a positional tag outside of near field communications requires, relative to the form factor, a considerable amount of power.
Thus, battery life of positional tags is often limited.
In addition, long-range communication for such a device is relatively expensive and often requires sophisticated circuitry for operating in connection with an associated electronic device (e.g., a mobile device).
Additionally, low-power options for positional tags are often limited to communicating with nearby objects that may require a user associated with the tracking device(s) to be within a close proximity (e.g., near field) of the positional tags, limiting the usefulness of such devices.

Abstract

Methods for performing power management of a multi-interface transponder (MIT) device, e.g., such as positional tag device. The MIT device may transition between various power states, e.g., based on detected events, such as detecting movement of the MIT device, receiving a wakeup signal, receiving an indication of a transition in transportation mode, and / or detecting that the MIT device may be lost, such as based on a lack of contact with another device for more than a threshold period of time.

Description

PRIOIRTY DATA[0001]This application claims benefit of priority to U.S. Provisional Application Ser. No. 62 / 810,492, titled “Multi-Interface Transponder Device”, filed Feb. 26, 2019, which is hereby incorporated by reference in its entirety as though fully and completely set forth herein.FIELD[0002]The present application relates to wireless communications, including techniques for the design and operation of a multi-interface radio frequency transponder device (or “tag”).DESCRIPTION OF THE RELATED ART[0003]Positional tags, such as electronic tracking devices, have created numerous ways for users to track locations of associated people and / or objects. For example, global positioning system (GPS) technology can be used to determine the location of a tagged object associated with a person, and the location can be communicated to another device. As a further example, a positional tag could be attached to an item of importance (e.g., keys, wallet, briefcase, article of clothing, backpack...
