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.
Claims20
A transponder device, comprising:
- a memory;
- a power source;
- and
- at least one processor in communication with the memory and the power source;
- wherein the at least one processor is configured to cause the transponder device to selectively operate in:
- a first mode, wherein the transponder device transmits beacons at a first transmission power and a first transmission rate;
- a second mode, wherein the transponder device transmits beacons at a second transmission power and a second transmission rate, wherein the second transmission power is greater than the first transmission power and the second transmission rate is less than the first transmission rate, and wherein the second mode is not entered until a duration of time since a last location update passes a threshold amount of time;
- and
- a third mode, wherein the transponder device does not transmit beacons.
A non-transitory computer readable memory medium storing program instructions executable by processing circuitry of a transponder device to cause the transponder device to:
- selectively operate in:
- a first mode, wherein the transponder device transmits beacons at a first transmission power and a first transmission rate;
- a second mode, wherein the transponder device transmits beacons at a second transmission power and a second transmission rate, wherein the second transmission power is greater than the first transmission power and the second transmission rate is less than the first transmission rate;
- and
- a third mode, wherein the transponder device does not transmit beacons;
- and
- select a mode of the first mode, second mode, or third mode to conserve power of a power source of the transponder device based, at least in part, on of a duration of time since a last location update of the transponder device.
An apparatus, comprising:
- a memory;
- and
- at least one processor in communication with the memory, wherein the at least one processor is configured to selectively operate in:
- a first mode, wherein the at least one processor generates instructions to transmit beacons at a first transmission power and a first transmission rate over a first interface in communication with the at least one processor;
- a second mode, wherein the at least one processor generates instructions to transmit beacons at a second transmission power and a second transmission rate over a second interface in communication with the at least one processor, wherein the second transmission power is greater than the first transmission power and the second transmission rate is less than the first transmission rate;
- and
- a third mode, wherein the at least one processor generates instructions to not transmit beacons.
