Title: Ray lose condition auto inspection method of optical scanner
Inventor: Cai zhen-cai
IPC: H04N17/00
Filed: 1998-06-10
Granted: 1999-09-11
Abstract: A kind of image quality inspection scanning method, can automatically inspect ray lose condition and computation of quantity of lose ray. After this invention reading incline ray of testing image, computing a medium gray value, set up a standard difference, in the first print image of the incline ray, searching for image element of a gray value closest to the medium gray value, to take the said image element (Xi, Yj) as standard, beginning the comparison of gray values. The comparison procedure is, first to compare gray media of image elements located at (Xi, Yj) and (Xi-1, Yj+1). If the compared value is greater than a set up value, it indicates that there is lose ray condition. But in order to compute losing how many rays, needs to compare to image element (Xi-2, Yj+1) of adjacent (Xi-1, Yj+1), to proceed the comparison until comply with the set up comparing condition, it is, gray media of (Xi, Yj) is smaller than (Xi-1, Yj+1), and gray media of (Xi, Yj) is greater than (Xi-2, Yj+1). If image gray media value difference of (Xi, Yj) and (Xi-1, Yj+1) is within the allowable error, it indicates there is no ray lose, can proceed to next comparison. During the comparing process to accumulate the lost ray quantity, and to frame the ray lose position. After completing the comparison, to output the quantity of ray lose, and indicate the ray lose position and judgment of qualified or not.

Title: Method for accepting an ink jet print cartridge
Inventor: HAARZ LEEA DANIELLE
IPC: B41J2/16
Filed: 1998-08-03
Granted: 2001-06-07
Abstract: A process is provided for forming a barrier layer over one or more extending sections of a flexible circuit and one or more bond pads of a print cartridge printhead using an encapsulant material and subsequently inspecting the print cartridge to determine if the encapsulant material has been properly placed on the print cartridge. The process involves providing an inspection mark on an orifice plate of the printhead before the barrier layer is formed. After the barrier layer has been formed, an inspection is made to determine if the barrier layer extends beyond the inspection mark and contacts a second portion of the print cartridge. If it does, then the print cartridge is unacceptable. If not, then the print cartridge is acceptable. Alternatively, the location of the barrier layer may be considered unacceptable if it contacts any portion of the inspection mark even though it may not contact the second portion of the print cartridge.

Filed: 1998-11-10
Granted: 2002-03-01
Abstract: The spray nozzle (5) comprises a mixing chamber (15) into which a liquid (7), forming a first and a second liquid stream (12, 13), can flow through two inlet openings (9, 10) and which comprises an outlet opening (30), disposed downstream, for a spray jet (40).

Title: Pre-boot security controller
Inventor: HUANG JUNG-CHIH
IPC: G06F21/22
Filed: 1999-11-18
Granted: 2001-05-28
Abstract: A pre-boot security controller in an electronic device is energized even though a power subsystem does not energize operation of a digital computer in the device. The security controller stores supervisor and user passwords in a nonvolatile password memory for comparison with a password entered using a security keypad. Upon entry of a matching password, the security controller enables the power subsystem to energize operation of the digital computer, and the security controller transitions from a security to an application operating mode. In the application operating mode, the pre-boot security controller preserves data about pressings of the security keypad. A computer program executed by the digital computer may respond to recorded keypad pressing by initiating execution of a specific application computer program that a user associates with a specific key on the security keypad.
