Patent number: 6556688Abstract: A steganographic method embeds hidden information like digital watermarks and digital fingerprints into an image by applying one or more zero-mean patches to a digital signal that conveys the image. Each zero-mean patch comprises elements having an average value substantially equal to zero. A printer tracking system is implemented by selecting a plurality of zero-mean patches according to a string of bits representing a printer serial number, and modifying printer control signals to embed the plurality of patches in each of a number of virtual cells within the image to be printed. The offset of the virtual cells with respect to the boundaries of the image and the location of the patches within each virtual cell are established in pseudo-random fashion. The printer tracking system further includes a technique for subsequently detecting the printer serial number by scanning the printed image and running a detection algorithm on the scanned data to recover the string of bits embedded in the zero-mean patches.Type: GrantFiled: March 15, 1999Date of Patent: April 29, 2003Assignee: Seiko Epson CorporationInventor: Viresh Ratnakar

Patent number: 6491378Abstract: In an ink jet head that reduces failure or abnormality in ink ejection, electric charge/discharge is applied between opposed electrodes and diaphragms to eject ink droplets from ink nozzles. Each of the opposed electrodes includes a main electrode and a sub-electrode formed on the nozzle side and in common with sub-electrodes for the other diaphragms. Auxiliary electric charge is applied between the sub-electrode and the diaphragms so that the menisci or ink in the ink nozzles vibrate without ejecting unnecessary ink droplets and to shorten the time for tail portions of ejected ink columns to leave the ink nozzles. Ink in ink channels is diffused so that the ink viscosity does not increase due to evaporation of ink solvent. Also, the menisci in the nozzles are drawn into the ink chambers so that unnecessary ink droplets are not ejected immediately after printing ink droplets are ejected.Type: GrantFiled: January 4, 2001Date of Patent: December 10, 2002Assignee: Seiko Epson CorporationInventors: Masahiro Fujii, Hiroyuki Ishikawa, Yasushi Matsuno
