1. A missing label detection system, the system comprising:
- a portable scanning device, the portable scanning device comprising;
a reader configured to read machine-readable elements and output identifiers encoded in the machine-readable elements;
an accelerometer configured to sense acceleration of the portable scanning device and output acceleration data corresponding to the sensed acceleration;
a memory to store the identifiers and the acceleration data; and
a controller operatively coupled to the reader, the accelerometer, and the memory, the controller configured to (i) control the reader to read a first one of the machine-readable elements disposed at a first location, (ii) control the reader to read a second one of the machine-readable elements disposed at a second location, and (iii) determines a cumulative change in the acceleration data from the first location to the second location as a result of movement of the portable scanning device from the first location to the second location and in response to the reading of the second one of the machine-readable elements; and
a computing system in communication with the portable scanning device,wherein at least one of the controller or the computing system determines a relative distance travelled by the portable scanning device from the first location to the second location based on the cumulative change in the acceleration data between the first and second locations, andwherein the computing system is programmed to determine whether the second one of the machine-readable elements is located at a designated location based on a difference between the relative distance and an expected distance between the first and second locations.

Abstract
Described in detail herein are methods and systems for detecting missing or miss positioned labels. The system can include a portable scanning device to scan machine-readable elements included on labels at a first and second location. The portable scanning device can detect the acceleration and the cumulative change between the first and second location. The portable scanning device or a computing system can determine the distance between the first and second location based on the acceleration data. The computing system can place a data point on a map of an estimated location of the location of the first scan and the location of the second scan.

10. A missing label detection method, the method comprising:
-
controlling, a reader of a portable scanning device to read a first machine-readable element disposed at a first location; controlling the reader to read a second machine-readable element disposed at a second location; determining a cumulative change in acceleration data from the first location to the second location based on an output accelerometer of the portable scanning device as a result of movement of the portable scanning device from the first location to the second location and in response to the reading of the second one of the machine-readable elements; determining a relative distance travelled by the portable scanning device from the first location to the second location based on the cumulative change in the acceleration data between the first and second locations; and determining whether the second machine-readable element is located at a designated location based on a difference between the relative distance and an expected distance between the first and second locations. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
