Scanner reader Active-X plug-in
The present invention enables the transfer of data from barcode scanners to computers for use with various software applications. An Active-X plug-in is downloaded to the user's computer the first time they access an application and need to use the scanner to upload information they have scanned using the barcode scanner. The Active-X plug-in aids the transfer and translation of data from the user's computer to the dedicated servers through the application. The Active-X plug-in is compiled code that resides on the user's machine making function calls to system files that interact with the barcode scanner by communicating with the machine's COM ports. Once the Active-X plug-in gathers the data from the scanner, the data can be used by the host application or posted to the Internet via XML.
1 . An Active-X plug-in for uploading information from barcode scanners comprising:
a polling routine which constantly polls all available communication ports of the computer to determine if a barcode scanner is attached;
a detection engine to determine the type of said barcode scanner upon detection by said polling routine; and
an upload engine for transferring barcode information stored on said barcode scanner to said computer.
2 . An Active-X plug-in according to claim 1 , further comprising:
a translation engine for formatting said uploaded barcode information from said barcode scanner for use with a software application located on said computer.
3 . An Active-X plug-in according to claim 1 , further comprising:
a posting routine for transmitting said uploaded barcode information to a network location.
4 . An Active-X plug-in according to claim 3 , wherein said network location is a universal resource locator.
5 . An Active-X plug-in according to claim 3 , wherein said barcode information is transmitted via XML.
6 . An Active-X plug-in according to claim 2 , wherein said barcode information is converted to a character delimited format.
7 . An Active-X plug-in according to claim 1 , wherein said Active-X plug-in is automatically downloaded when the said barcode scanner is attached to said computer for the first time.
8 . An Active-X plug-in according to claim 1 , wherein said barcode scanner is a laser-based barcode scanner.
9 . An Active-X plug-in according to claim 1 , wherein said barcode scanner is attached to said computer via a proprietary wire.
10 . An Active-X plug-in according to claim 1 , wherein said barcode scanner is attached to said computer via at least one from the group consisting of a serial port, a USB port, a parallel port, a RS-232 port, a PS/2 port, and a Firewire port.
11 . A process for uploading information from a barcode scanner to a computer comprising the steps of:
scanning at least one barcode with a barcode scanner;
connecting said barcode scanner to a computer;
detecting said barcode scanner attached to said computer via an Active-X plug-in installed on said computer, wherein said Active-X plug-in detects said barcode scanner by constantly polling all available ports of said computer; and
uploading said barcode information from said barcode scanner to said computer utilizing said Active-X plug-in.
12 . A process for uploading information from a barcode scanner to a computer according to claim 11 , further comprising the step of:
formatting said uploaded barcode information for use with a software application located on said computer.
13 . A process for uploading information from a barcode scanner to a computer according to claim 11 , wherein said step of uploading is initiated by a user of said computer.
14 . A process for uploading information from a barcode scanner to a computer according to claim 11 , wherein said step of uploading occurs automatically in response to the detection of said barcode scanner.
