Network server for providing scanning functionality to a computer
A server enables a user at a station to scan a document. The station has a computer connected to the network, a browser installed on the computer to enable the user to browse the network, and a scanner in communication with the computer. The server has a database of scanner drivers, a driver selection system that enables the user to select a driver for the scanner from the database of scanner drivers, and a delivery system that transfers a selected driver to the computer and causes the computer to execute the driver. The user uses the browser and the driver selection system to select a driver for the scanner. The delivery system then sends the driver to the computer, and the computer executes the driver. The driver uses the scanner to scan a document, and scanning data corresponding to the document is saved in a predetermined location.
1. Field of the Invention
The present invention concerns a network server. More specifically, a network server is disclosed that enables a user to use a scanner by downloading the driver for the scanner.
2. Description of the Prior Art
The explosion of the Internet has coincided with the rising popularity of portable computing. Many people now prefer to buy laptop computers in lieu of traditional desktop computers for, despite the added expense, being able to carry their computers wherever they go is a great convenience for these users. The introduction of the universal serial bus (USB) standard for linking peripheral devices to computers has further simplified the computing environment. Whereas before the advent of. USB a plurality of different connection-schemes were used to link, say, various scanner models to a computer, now a single USB port can be used to connect to any type of scanner. This has been of great benefit to the users of portable computers as they may now bring their computers to a remote location and, if a scanner is available and is USB compatible, they can easily connect their computer to the scanner.
Although the scanner and the physical connection may be available at a remote site, the necessary driver software for the scanner may not be. Generally, scanner driver software is resident on the host computer. If the host computer is moved, as is the case for laptop computers, to a new location with a different type of scanner, the driver software will not be able to properly communicate with the different scanner. Thus, though a resource is physically available, it is still unusable. This can be a source of considerable frustration for users.
SUMMARY OF THE INVENTIONIt is therefore a primary objective of this invention to provide a server on a network that allows a user on a host computer to download and execute driver software to perform a scan. The scanned image may be saved on the host computer, the server, or another remote location.
The present invention, briefly summarized, discloses a server for a network. The server enables a user at a station to scan a document. The station has a computer connected to the network, a browser installed on the computer to enable the user to browse the network, and a scanner in communication with the computer. The server has a database of scanner drivers, a driver selection system that enables the user to select a driver for the scanner from the database of scanner drivers, and a delivery system that transfers a selected driver to the computer and causes the computer to execute the driver. The user uses the browser and the driver selection system to select a driver for the scanner. The delivery system then sends the driver to the computer, and the computer executes the driver. The driver uses the scanner to scan a document, and scanning data corresponding to the document is saved in a predetermined location. It is an advantage of the present invention that the user does not need to have scanner driver software pre-installed on the computer to use the scanner. In this manner, the user can connect to any of a plurality of supported scanners and use the scanners without any concern about not having appropriate supporting software. Additionally, with a well-managed database, the user is assured of receiving the most up-to-date scanner drivers possible. Also, the server permits the user to save the scanning data either in an account on the server, at another address on the network, or on the computer.
These and other objectives of the present invention will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment, which is illustrated in the various figures and drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
Please refer to
Each station 20 comprises a computer 22 in communications with a scanner 24. The scanner 24 may be electrically connected to the computer 22 to establish the communications, but need not necessarily be so. For example, a wireless standard, such as Bluetooth, could be used to establish communications between the scanner 24 and the computer 22. The computer 22 is any sort of computing device, such as a portable computer, a desktop computer, a personal data assistant (PDA), etc. The computer 22 comprises a memory 26. This memory 26 may include working memory for the computer 22, such as dynamic random access memory (DRAM), or permanent storage memory, such as a hard disk. Held within the memory 26 is a browser program 28. When executed by the computer 22, the browser 28 enables a user to browse information across the network 30. Specifically, the browser 28 permits the user to access the server 10.
The server 10 comprises a login system 40. Please refer to
The server 10 also comprises a driver selection system 60. Please refer to
When the user clicks a “scan now!” button 62a, the browser 28 sends the selected driver information in the driver selection box 66, the check state of the check boxes 82 and 84, and destination information in the textbox 86 to the server 10. A destination selection system 80 within the server 10 uses the check state of the check boxes 82 and 84, and any textual information from the textbox 86 to generate a destination address 83 for scanning data. The destination address 83 indicates where the scanning data should be saved after a scan with the scanner 24 has been completed. If the check box 82 is checked, then the address 83 simply indicates the account 58 of the user. If the check box 84 is checked, then the destination selection system 80 must properly parse the textual information from the textbox 86 to determine what the address 83 should be, and may need to append a default filename onto the address specified in the textbox 86 if the user merely indicated a destination directory. The destination selection system 80 may also verify write permission to any specified URL, and warn the user if the URL is not a valid destination.
After the destination selection system 80 has created the destination address 83, a delivery system 90 generates a transfer file 92. The transfer file 92 is a self-extracting executable file that contains a driver 72 from the database 70. The delivery system 90 selects a driver 72 from the database 70 according to the user-selected scanner driver type, which is obtained from the driver selection system 60 by way of data received from the browser 28 from the driver selection box 66. The self-extracting transfer file 92 may also contain the address 83 so that the driver 72 in the transfer file 92 will know where to send or save the scanning data. The delivery system 90 sends the transfer file 92 to the computer 22, and causes the computer 22 to execute the transfer file 92. When executed by the computer 22, the self-extracting transfer file 92 extracts the driver 72 and address 83, and executes the driver 72. The driver 72 interfaces with the scanner 24 and performs a scan of a document. Data from the scan is then saved at the location indicated by the address 83. In this manner, scanning data is saved either in the user account 58, is sent to an e-mail address, saved at a URL or saved in the memory 26 of the computer 22. After the driver 72 has finished the scanning of the document, and the saving of the scanning data, the driver 72 may cause itself to be erased from the memory 26, along with the self-extracting transfer file 92. This is done to prevent the memory 26 from becoming cluttered with unnecessary drivers 72 and old self-extracting transfer files 92. It should also be noted here that it is not absolutely necessary for the destination address 83 to be inserted into the self-extracting file transfer file 92 by the delivery system 90. When executed by the computer 22, it is also possible for the driver 72 to poll the server 10 to get the destination address 83.
The driver and destination page 62 also has a “view scans” button 62b. When clicked, the “view scans” button 62b enables the user to view scanning data stored in the user account 58. Please refer to
Finally, it should be noted that, although the above discussion has been with reference to a moved computer using a new scanner, the present invention serves equally well for a moved scanner being connected to a new computer. That is, if a user carries his or her scanner 24 to a location having a different computer 22, it is fully possible that the computer 22 will not have a proper driver for the scanner 24. Nevertheless, the user can use the browser 28 to connect to the server 10 and obtain an appropriate driver 72.
Those skilled in the art will readily observe that numerous modifications and alterations of the server and station may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
