Publication number: 20240274681Abstract: An enhancement mode gallium nitride (GaN) transistor with a p-type gate configured to eliminate holes accumulating under the gate metal. The gate has two electrodes, a gate electrode and a hole collector electrode. In a preferred embodiment, a negative voltage is applied to the hole collector electrode, attracting holes accumulating under the gate metal. The attracted holes recombine with electrons supplied by the negative voltage, thereby substantially eliminating the holes.Type: ApplicationFiled: February 8, 2024Publication date: August 15, 2024Applicant: Efficient Power Conversion CorporationInventors: Robert Strittmatter, Jianjun Cao, Robert Beach, Muskan Sharma, Wen-Chia Liao, Alexander Lidow, Massimo Grasso, Sergio Morini

Publication number: 20150310319Abstract: A method of rendering a graphical object (e.g., 801) on a page (800), is disclosed. A region of the page containing the graphical object (801) is marked as output incompatible based on the graphical object (801) being output incompatible. A bounding box comprising the marked region is determined. A proportion of a number of the regions marked as output incompatible are determined to a total number of regions in the bounding box. A further region within the bounding box is marked as output incompatible to increase the determined proportion above a threshold. The graphical object in the marked region and the further marked region is converted into an output compatible graphical object if the determined proportion is above the threshold. The output compatible graphical object is rendered.Type: ApplicationFiled: July 8, 2015Publication date: October 29, 2015Inventors: Alexander Will, Thomas Benjamin Sanjay Thomas, Delilah Gloria Slack-Smith, Cuong Hung Robert Cao, Sheng Wu

Patent number: 8907956Abstract: A method for generating an outline for a stroked line of specified width from an input line (601) defined by a vector having two input points (P0, P1) is disclosed. The method comprises the steps of: determining an offset vector based on the vector, the offset vector having components [Xoff, Yoff]; determining a first set of two pairs of points (L1, L2 and R1, R2) based on the offset vector applied to the two input points (P0, P1); and determining a second set of two pairs of points (L0, L3 and R0, R3) based on the first set of points (L1, L2 and R1, R2). The second set of two pairs of points (L0, L3 and R0, R3) defines at least a portion of the outline and one of the components of the offset vector [Xoff, Yoff] is independent of the inclination of the vector and the specified width.Type: GrantFiled: July 9, 2009Date of Patent: December 9, 2014Assignee: Canon Kabushiki KaishaInventor: Cuong Hung Robert Cao

Publication number: 20100315431Abstract: A method of modifying drawing commands to be input to a rendering process is disclosed. The method detects a first glyph drawing command and detects a predetermined number of further glyph drawing commands proximate within a threshold of the first glyph drawing command. The predetermined number of proximate glyph drawing commands is accumulated. The accumulated proximate glyph drawing commands are combined into a 1-bit depth bitmap. The 1-bit depth bitmap is output to the rendering process as a new drawing command.Type: ApplicationFiled: June 11, 2010Publication date: December 16, 2010Applicant: CANON KABUSHIKI KAISHAInventors: David Christopher Smith, Alexander Will, Cuong Hung Robert Cao

Patent number: 7746361Abstract: A method is described for determining a discrete boundary for an object to be rendered into a raster pixel image having a plurality of scanlines. In the method, the object is rotated by an integer multiple of 90 degrees, and an outline of the rotated object is decomposed into line segments. For each scanline to be rendered, points of intersection between the line segments and the scanline are determined, and each point of intersection is rounded to an adjacent position selected from a finite set of positions on the scanline using a rule chosen according to the amount of rotation. The rounded points of intersection delimiting the discrete boundary. If the object is rotated by odd multiple of 90 degrees the method includes the steps of identifying points of intersection that satisfy a predetermined criterion; and shifting the identified points of intersection prior to rounding.Type: GrantFiled: August 11, 2005Date of Patent: June 29, 2010Assignee: Canon Kabushiki KaishaInventor: Cuong Hung Robert Cao

Patent number: 7551173Abstract: A method (2500) of converting a monotonic curve into edge information is disclosed. A method (2800A) of determining an integer edge crossing value, Xi, for a new edge crossed by a scanline (i.e., an inactive edge being crossed by the scanline for the first time) is also disclosed. Further, a method (2800B) of determining an integer edge crossing value, Xi, for an active edge crossed by a scanline, is also disclosed. The disclosed methods have general application in the representation of monotonic curves. The described methods allow monotonic curves to be accurately represented in terms of edges where the original curve can be reconstructed from the edges. Furthermore, the methods allow edge tracking to be performed such that any resulting error is restricted to a fixed-point division error. At transition points between adjoining segments, an original edge crossing point may be determined to avoid accumulated error.Type: GrantFiled: November 23, 2004Date of Patent: June 23, 2009Assignee: Canon Kabushiki KaishaInventor: Cuong Hung Robert Cao
