Handheld Code Reader Having A Motion Sensor
First Claim
1. A method for use with a handheld code reader that has an operating characteristic that can have at least first and second different states, the method for switching between the different states of the operating characteristic, the method comprising the steps of:
- specifying a circumstance set including at least one of reader orientation and a threshold movement level for the reader;
monitoring at least one of movement and orientation of the reader;
determining when the circumstance set occurs; and
changing the operating characteristic state when the circumstance set occurs;
wherein the operating characteristic is one of an illumination mode and a code decoding algorithm.

Abstract
A method and apparatus for use with a handheld code reader that has an operating characteristic that can have at least first and second different states, the method for switching between the different states of the operating characteristic, the method comprising the steps of specifying a circumstance set including at least one of reader orientation and a threshold movement level for the reader, monitoring at least one of movement and orientation of the reader determining when the circumstance set occurs and changing the operating characteristic state when the circumstance set occurs, wherein the operating characteristic is one of an illumination mode and a code decoding algorithm.

13. A method for use with a handheld code reader to select at least one reader operating characteristic, the method comprising the steps of:
-
detecting movement of the handheld code reader; and determining, based on the movement of the reader, an optimum setting for the at least one reader operating characteristic; wherein the at least one operating characteristic includes at least one of lens focus and exposure time. - View Dependent Claims (14, 15, 16, 17)

18. An apparatus for use with a handheld code reader that has an operating characteristic that can have at least first and second different states, the apparatus for switching between the different states of the operating characteristic, the apparatus comprising:
-
a sensor for detecting at least one of movement of the handheld code reader and orientation of the reader; a comparator for comparing the at least one of detected reader movement and reader orientation to at least one of a threshold movement level and a specific orientation and determining at least one of when the detected reader movement exceeds the threshold movement level and the reader is oriented in the specific orientation; and a characteristic selector for changing between the different states of the operating characteristic when the at least one of detected reader movement exceeds the threshold movement level and the reader is in the specific orientation; wherein the operating characteristic is one of an illumination mode and a code decoding setting. - View Dependent Claims (19, 20, 21)

22. An apparatus for use with a handheld code reader to select at least one reader operating characteristic, the apparatus comprising:
-
a sensor for detecting movement of the handheld code reader; a processor for determining, based on the movement of the reader, an optimum setting for the at least one reader operating characteristic; and a characteristic controller for selecting optimum characteristic settings for the code reader as a function of the reader movement; wherein the at least one operating characteristic includes at least one of lens focus and exposure time. - View Dependent Claims (23, 24, 25)
