Abstract
A method for locating an object in a facility includes determining position with respect to time of a material handling device associated with a movable vehicle within the facility Signal strength of a signal emitted by at least one identification tag affixed to the object is measured with respect to time. A time that the object is deposited at a fixed position by the material handling device is determined from the measured signal strength. The location in the facility of the fixed position is established using the determined time and the determined position with respect to time.
Claims18
A method for locating an object in a facility, comprising:
- determining position with respect to time of a material handling device associated with a movable vehicle within the facility;
- measuring with respect to time signal strength of a signal emitted by at least one identification tag affixed to the object;
- determining from the measured signal strength a time that the object is deposited at a fixed position by the material handling device;
- and
- establishing the location in the facility of the fixed position using the determined time and the determined position with respect to time.
A computer program stored in a non-transitory computer readable medium, the computer program comprising logic operable to cause a programmable processor to perform actions comprising:
- determining position with respect to time of a material handling device associated with a movable vehicle within a facility;
- measuring with respect to time signal strength of a signal emitted by at least one identification tag affixed to an object;
- determining from the measured signal strength a time that the object is deposited at a fixed position by the material handling device;
- and
- establishing the location in the facility of the fixed position using the determined time and the determined position with respect to time.
A method for locating an object in a facility, comprising:
- determining position with respect to time of a movable vehicle within the facility;
- measuring with respect to time signal strength of a signal emitted by at least one identification tag affixed to the object at least three different positions of the movable vehicle;
- establishing a location in the facility of the identification tag using the signal strength at the at least three different positions.
