Abstract: A method of operating a computer system, in particular a microcomputer havin g a storage device shared between several application programs, comprises a backup process including a process for maintaining a record of changes made to the data on the storage device whilst the backup process is executing. The record is used to ensure that the data seen by the backup process does not change while it is executing whilst allowing other processes to continue to update the storage device normally thereby avoiding delays associated with file locking techniques. The additional operations are executed at the level of the operating system interface of the microcomputer in such a manner that normal use of the computer is unaffected.

Abstract: A trouble-shooting mechanism is incorporated into a telephone service technician's portable computer unit, to enable a craftsperson, to respond to a trouble ticket. By analyzing multiple sources of information, including user inputs from the craftsperson, parametric data embedded in the trouble ticket, test data obtained through the execution of local tests, and remote test data, the trouble-shooting mechanism derives and suggests a problem solving strategy that is appears accurate. The system architecture includes a trouble-shooting application engine, and an associated set of databases, one of which is a knowledge database, and the other of which is a shared, parameter database. The knowledge database contains rules and static parameters which define the characteristics and behavior of the application engine. These rule sets and information are telephone line trouble-shooting specific.

Abstract: A method of using a laser to cut a groove or pocket of predetermined depth of less than about 0.005 inches in a stencil comprising a polyimide sheet having a thickness in the range of 0.005 to 0.012 inches comprising the steps of mounting the stencil on a movable work table and positioning and maintaining a laser a predefined distance from the polyimide sheet above the work table. A laser beam is directed against the polyimide sheet to cut an indentation into said polyimide sheet. The laser beam has a pulse duration and a power level to make the cut into the polyimide sheet. The method further includes the step of directing a gas against the polymide sheet where the laser beam cuts into said polyimide sheet. The gas is pressurized. The depth of the indentation cut into the polyimide sheet by the laser is determined by choosing the pressure of the gas relative to choosing the pulse duration and the power level of the laser beam. The work table is moved relative to the laser whereby the indentation cut into the polyimide sheet creates a groove or pocket as the laser beam moves across the polyimide sheet. By controlling the pressure of the gas normally used to remove dross from the cut edges of the material, the cutting process can be better controlled so that laser milling of polyimide sheet is reliably obtained.

Abstract: An external control system for a laser system, used as an illumination source for a stepper system, is provided. The external control allows for a measuring of the energy actually distributed to a wafer and a correction of the energy dose distribution based upon this measurement. In this way, a more precise energy dose control is achieved. The external control communicates with the laser's own internal control system to provide serial inputs which allow for corrections to be made to the High Voltage setting based upon the aforementioned measurements, and coordinates with the laser's internal control system to initiate laser operation at the required intervals.
