Latest Patents

One of his latest patents is a software validation method and system. This invention tests revisions made to printer graphics interpreter software. A test suite of POSTSCRIPT, PCL, or other high-level printer languages is input to a production version of a printer's internal interpreter software. A first bit-map is generated by the interpreter that is normally used to control each pixel in the printing of a page. The same test suite is fed to a work-in-progress revision of the printer's internal interpreter software, generating a second bit-map. The first and second bit-maps are subtracted from one another, and a difference bit-map is inspected. If only minor shifts of objects are noted, or if no differences at all are apparent, the work-in-progress revision is accepted as the new production standard. The second bit-map is then used to replace the first. Otherwise, the work-in-progress revision of the printer's internal interpreter software is reworked to correct the printing interpretation errors it was making.

Another significant patent is the job token printer assignment system. In this system, a client provides a job ticket token to a print server, which contains the profile of a print job to be printed. The print server parses the job ticket token, determines an appropriate printer for the print job, and returns a selected printer token to the client, which includes the network address and name of the selected printer. The client then sends the print job, accompanied by the selected printer token, to the appropriate printer. This system allows the print server to avoid spooling large print jobs, as it only needs to identify the characteristics contained in the job ticket token and assign the print job to an appropriate printer.
