Abstract
Methods and systems to determine a change in a location of a device relative to an initial location of the device are provided. The method includes periodically receiving a parameter of the device and determining the change in the location of the device relative to an initial location of the device based on a change in the parameter over a period of time. In an example, the method includes determining a first trend in the parameter over a first period of time, determining a second trend in the parameter over a second period of time, and determining a change in the location of the device from a first location to a second location by comparing the first trend to the second trend.
Claims29
A method to determine a change in a location of a device relative to an initial location of the device, comprising:
- receiving a physical parameter of the device;
- generating a first trend for the physical parameter over a first period of time;
- generating a second trend for the physical parameter over a second period of time;
- and
- determining the change in the location of the device relative to the initial location of the device based on a change between the first trend and the second trend.
A system to detect a change in a location of a device relative to an initial location of the device, comprising:
- a downstream physical layer (PHY) configured to receive a physical parameter of the device;
- and
- a control unit configured to:
- generate a first trend for the physical parameter over a first period of time,
- generate a second trend for the physical parameter over a second period of time, and
- determine the change in the location of the device relative to the initial location of the device based on a change between the first trend and the second trend.
A system to determine a change in a location of a device relative to an initial location of the device, comprising:
- a memory configured to store instructions;
- a processor, coupled to the memory, configured to, based on the instructions stored in the memory:
- receive a physical parameter of the device;
- generate a first trend for the physical parameter over a first period of time;
- generate a second trend for the physical parameter over a second period of time;
- and
- determine the change in the location of the device relative to the initial location of the device based on a change between the first trend and the second trend.
A media player, comprising:
- a sensor configured to measure a physical parameter associated with the media player;
- an upstream physical layer (PHY) configured to transmit the physical parameter to a device;
- wherein a change in a first trend for the physical parameter over a first period of time compared to a second trend for the physical parameter over a second period of time is configured to indicate a change in a location of the media player relative to an initial location of the media player.
A system to detect a change in a location of a device from a first location associated with a first rate to a second location associated with a second rate, comprising:
- a downstream physical layer (PHY) configured to receive a physical parameter of the device;
- and
- a control unit configured to determine the change in the location of the device from the first location associated with the first rate to the second location associated with the second rate when a change in a first trend for the physical parameter over a first period of time compared to a second trend for the physical parameter over a second period of time;
- and
- transmit a message to the device indicating unauthorized use of the device in the second location.
A system to detect a change in a location of a device from a first location to a second location, comprising:
- a downstream physical layer (PHY) configured to receive a physical parameter of the device;
- and
- a control unit configured to:
- determine a first trend in the physical parameter over a first period of time,
- determine a second trend in the physical parameter over a second period of time, and
- determine the change in the location of the device from the first location to the second location based on a comparison of the first trend to the second trend to determine a change between the first trend and the second trend.
