Abstract
Abstract A method and apparatus for operating a hand-held bar code scanning device having a processor for operating the scanning device. The method includes the steps of mounting the scanning device in a support member, sensing the movement of the device when removed from the support member, operating the device when removed from the support member and disabling the scanning device when returned to the support member. A hand-held scanning device includes sensing means and processing means in which the sensing means outputs a control signal to the processing means upon sensing the movement of the scanner enabling the processing means to operate the scanner.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
173 words
A hand-held optical bar code scanner including a body portion and a handle portion comprising; a scanning unit for generating a scan pattern for scanning a bar code label; processing means mounted in said body portion for operating said scanning unit when enabled; and sensing means mounted in said handle portion and coupled to said processing means for sensing movement of the scanner, said sensing means outputting a control signal to said processing means upon sensing the movement of the scanner enabling said processing means to operate said scanner, said sensing means including a light detector mounted in the handle portion of the scanner for detecting the occurrence of the grasping of the handle of the bar code scanner by the operator, said light detector normally sensing the ambient light impinging on the scanner and outputting said control signal to said processing means upon the grasping of the handle portion by the hand of the operator which removes said ambient light from said light detector enabling the processing means to operate the scanner.
Claim 2
Dependent Claim
173 words
A hand-held optical bar code scanner including a body portion and a handle portion comprising; a scanning unit for generating a scan pattern for scanning a bar code label; processing means mounted in said body portion for operating said scanning unit when enabled; and sensing means mounted in said handle portion and coupled to said processing means for sensing movement of the scanner, said sensing means outputting a control signal to said processing means upon sensing the movement of the scanner enabling said processing means to operate said scanner, said sensing means including a light detector mounted in the handle portion of the scanner for detecting the occurrence of the grasping of the handle of the bar code scanner by the operator, said light detector normally sensing the ambient light impinging on the scanner and outputting said control signal to said processing means upon the grasping of the handle portion by the hand of the operator which removes said ambient light from said light detector enabling the processing means to operate the scanner.
Claim 3
Independent Claim
150 words
A method for operating an optical scanning device which includes the steps of: providing the optical scanning device with a handle portion for grasping by the hand of an operator; mounting the scanning device in a support member; mounting in the handle portion of the scanning device a light detector for sensing the grasping of the scanning device by the operator; sensing the grasping of the device by the operator in removing the scanner from the support member; operating the scanning device in response to sensing the grasping of the scanning device for scanning a bar code label; initiating a predetermined time of operation of the scanning device upon sensing the grasping of the scanning device; sensing the occurrence of a valid read operation during the operation of the scanning device; and disabling the operation of the scanning device upon sensing the release of said scanning device by the operator.
Claim 4
Independent Claim
150 words
A method for operating an optical scanning device which includes the steps of: providing the optical scanning device with a handle portion for grasping by the hand of an operator; mounting the scanning device in a support member; mounting in the handle portion of the scanning device a light detector for sensing the grasping of the scanning device by the operator; sensing the grasping of the device by the operator in removing the scanner from the support member; operating the scanning device in response to sensing the grasping of the scanning device for scanning a bar code label; initiating a predetermined time of operation of the scanning device upon sensing the grasping of the scanning device; sensing the occurrence of a valid read operation during the operation of the scanning device; and disabling the operation of the scanning device upon sensing the release of said scanning device by the operator.
Claim 5
Dependent Claim
78 words
The method of claim 2, further comprising the steps of: providing said scanning device with processing means coupled to said light detector for operating the scanning device when enabled; sensing ambient light impinging on the said light detector; and outputting a control signal to said processing means by said light detector upon the grasping of the handle by the operator which removes said ambient light from said light detector enabling the processing means to operate the scanning device.
