Abstract
Variable step tracking is described in which a monitoring station is operable to receive data signals representative of step movement of an asset as detected by a monitoring device carried by the asset. A database stores a step length of the asset. A step length modification module modifies the step length based on at least one of energy, asset orientation, direction, and frequency associated with the step movement. An asset position is estimated with respect to a known location based on cumulative step lengths.
Claims26
A variable step tracking device, comprising:
- a monitoring station operable to receive data signals representative of step movement of an asset as detected by a monitoring device carried by the asset;
- a database for storing a step length of the asset;
- a step length modification module for modifying the step length based on at least one of energy, asset orientation, direction, and frequency associated with the step movement;
- and
- a processor for estimating an asset position with respect to a known location based on cumulative step lengths.
A method for variable step tracking, comprising:
- measuring a step length of an asset;
- positioning the asset at a known location;
- detecting step movement of the asset using a movement detection device;
- logging data of the step movement as a function of time;
- and
- modifying the step length based on at least one of energy, asset orientation, direction, and frequency associated with the step movement.
A non-transitory computer readable storage medium having computer readable instructions embodied therein which, when executed by the processor, are operable to:
- measure a step length of an asset;
- position the asset at a known location;
- detect step movement of the asset using a movement detection device;
- log data of the step movement as a function of time;
- and
- modify the step length based on at least one of energy, asset orientation, direction, and frequency associated with the step movement.
