Abstract
There is provided a method for determining the change in horizontal or vertical position of a device, the method comprising obtaining a signal that represents an estimate of the position of the device in a horizontal or vertical direction over time; identifying a maximum position value and a minimum position value from a selected portion of the signal representing the estimate of the position of the device; and determining the change in position over the selected portion of the signal as the difference between the identified maximum position value and the identified minimum position value.
Claims15
A method for determining the change in horizontal or vertical position of a device, the method comprising:
- obtaining a signal that represents an estimate of the position of the device in a horizontal or vertical direction over time;
- identifying a maximum position value and a minimum position value from a selected portion of the signal representing the estimate of the position of the device;
- and
- determining the change in position over the selected portion of the signal as the difference between the identified maximum position value and the identified minimum position value.
An apparatus, comprising:
- processing means that is configured to:
- obtain a signal that represents an estimate of the position of a device in a horizontal or vertical direction over time;
- identify a maximum position value and a minimum position value from a selected portion of the signal representing the estimate of the position of the device;
- and
- determine the change in position over the selected portion of the signal as the difference between the identified maximum position value and the identified minimum position value.
