Automated System And Method To Discourage Access Of Unlicensed Peripheral Devices By A Computer System
US Patent:
5479612, Dec 26, 1995
Filed:
Apr 13, 1994
Appl. No.:
8/226922
Inventors:
Kenneth Kenton - Wilmington DE
Jeffery A. Stell - Exton PA
Richard A. Coffman - Phoenixville PA
Jeffery A. Stell - Exton PA
Richard A. Coffman - Phoenixville PA
Assignee:
Unisys Corporation - Blue Bell PA
International Classification:
G06F 1100
US Classification:
395186
Abstract:
System and method of encouraging computer system customers to purchase licenses before employing certain types of peripheral devices for use with their computer system. The computer system establishes contact with a peripheral device. It then verifies that the peripheral device is supported by the operating system. If the peripheral device is supported, the system determines whether the peripheral device is licensed (and therefore requires a driver license key in order for the peripheral device to be accessed by the system). If the peripheral device requires a driver license, the system determines whether the corresponding driver license key is installed in the keys file of the computer system. If the driver license key is not installed, the system compels (or encourages) installation of the driver license key by (1) displaying a licensing violation message instructing the customer to obtain the proper license; and/or (2) precluding access of the peripheral device by the computer system.
Self-Identifying Peripheral Device
US Patent:
6272560, Aug 7, 2001
Filed:
Oct 13, 1998
Appl. No.:
9/170341
Inventors:
Kenneth A. Kenton - Wilmington DE

Assignee:
Unisys Corporation - Blue Bell PA
International Classification:
G06F 300, G06F 1312
US Classification:
710 8
Abstract:
A method and apparatus enables a newly installed peripheral device such as a disk device to be used with a computer system without changing the operating system. The peripheral device is identified as a type which is not recognized by an operating system operating in conjunction with the computer system. A value which identifies at least one logical attribute of said peripheral device is obtained from said peripheral device. A determination is made as to whether the operating system and the peripheral device are compatible based on the logical attribute obtained from the peripheral device. The operating system and the peripheral device communicate if it is determined that the operating system and the peripheral device are compatible (i. e. , can operate together).
