Patent number: 11959432Abstract: A method of operating an engine is provided. An exhaust valve actuation fault is detected for a first exhaust valve associated with a first cylinder during a first working cycle. In response to the detection of the exhaust valve actuation fault, fueling to at least the first cylinder is cut off. Actuation of the first exhaust valve is attempted in second working cycles that follow the first working cycle, wherein the second working cycles are not fueled. Whether or not the first exhaust valve actuated properly during the second working cycles is determined. Operation of the first cylinder is resumed when it is determined that the first exhaust valve actuated properly. Operation of the first cylinder is not resumed when it is determined that the first exhaust valve did not actuate properly.Type: GrantFiled: March 8, 2023Date of Patent: April 16, 2024Assignee: Tula Technology, Inc.Inventors: Robert C. Wang, Louis J. Serrano, Shikui Kevin Chen

Patent number: 11951373Abstract: Methods and systems for use in automating or assisting umpiring of a baseball or softball game are described herein. A location of a strike zone is determined based on video images of a batter standing next to home plate captured by a camera. Locations of a ball traveling towards the batter, and locations of the bat being held by the batter, are autonomously tracked using computer vision based on video images captured by at least two cameras having different positions. Additionally, there are autonomous determinations of whether a location of the ball intersects with the strike zone, and whether the batter made a genuine attempt to swing the bat at the ball, and based one at least one of these determinations, there is an autonomous determination of whether a “strike” or a “ball” occurred. Additionally, an indication of whether a “strike” or a “ball” occurred is autonomously output.Type: GrantFiled: February 14, 2023Date of Patent: April 9, 2024Assignee: SPORTSMEDIA TECHNOLOGY CORPORATIONInventors: Josh D. Spivak, Graham W. Goldbeck, Ryan A. Zander, Ted C. Chen, Robert C. Amyx, James G. Painter

Patent number: 8156479Abstract: A system and method for monitoring dynamic scopes in a runtime environment is disclosed. The system and method utilizes an algorithm which may be applied to both synchronous and asynchronous invocations. The method comprises determining an initial scope of a source component, the initial scope being a scope of the source component upon providing a synchronous call to invoke a target component. The scope declaration specified by the target component is determined. A resultant scope present upon invocation of the target component is then determined. The resultant scope is determined based on the initial scope of the source component and the scope declaration specified by the target component. A record is stored in a centralized location identifying the resultant scope, and the target component as a participant in the resultant scope.Type: GrantFiled: December 7, 2007Date of Patent: April 10, 2012Assignee: International Business Machines CorporationInventors: Pamela H. Fong, Chendong Zou, Robert C. Chen, Edwin V. Sapugay

Patent number: 6522013Abstract: Punch-through vias are filled by initially depositing a thin, conformal layer of titanium nitride by chemical vapor deposition to cover an exposed upper surface of a lower metal feature, e.g. portions exposed by penetrating and undercutting an anti-reflective coating. A metal such as tungsten is subsequently deposited to fill the punch-through via. Embodiments include thermal decomposition of an organic-titanium compound, such as tetrakis-dimethylamino titanium, and treating the deposited titanium nitride in an H2/N2 plasma to lower its resistivity. Moreover, the thickness of the anti-reflective coating can be reduced and the process window for etching the via widened.Type: GrantFiled: August 19, 1998Date of Patent: February 18, 2003Assignee: Advanced Micro Devices, Inc.Inventors: Robert C Chen, Jeffrey A. Shields, Robert Dawson, Khanh Tran

Patent number: 6472751Abstract: A dielectric interlayer is formed over a semiconductor substrate comprising at least one active region. The exposed upper surface of the dielectric interlayer is treated with nitrogen to form a nitrided barrier layer thereon. At least one hydrogen-containing dielectric layer is formed over the dielectric interlayer having the nitrided barrier layer thereon. The nitrided barrier layer serves as a barrier to diffusion of hydrogen from the at least one hydrogen-containing dielectric layer into the dielectric interlayer, thereby preventing a decrease in hot carrier injection reliability.Type: GrantFiled: September 6, 2000Date of Patent: October 29, 2002Assignee: Advanced Micro Devices, Inc.Inventors: Robert C. Chen, Jeffrey A. Shields, Robert Dawson, Khanh Tran

Patent number: 6159851Abstract: Borderless vias are filled by initially depositing a thin, conformal layer of titanium nitride by chemical vapor deposition to cover an undercut, etched side surface of a lower metal feature. A metal, such as tungsten, is subsequently deposited to fill the borderless via. Embodiments include thermal decomposition of an organic-titanium compound, such as tetrakis-dimethylamino titanium, and treating the deposited titanium nitride in an H.sub.2 /N.sub.2 plasma to lower its resistivity.Type: GrantFiled: April 21, 1999Date of Patent: December 12, 2000Assignee: Advanced Micro Devices, Inc.Inventors: Robert C.

Patent number: 6060384Abstract: Spin-on HSQ is employed to gap fill metal layers in manufacturing a high density, multi-metal layer semiconductor device. The degradation of deposited HSQ layers during formation of borderless vias, as from photoresist stripping using an O.sub.2 -containing plasma, is overcome by treating the degraded HSQ layer with an H.sub.2 -containing plasma to restore the dangling Si--H bonds, thereby passivating the surface and preventing moisture absorption, before filling the via opening with conductive material, such as a barrier layer.Type: GrantFiled: October 23, 1998Date of Patent: May 9, 2000Assignee: Advanced Micro Devices, Inc.Inventors: Robert C.

Patent number: 6043147Abstract: Patterned metal layers are gap filled with HSQ and passivated to stabilize the dielectric constant of the HSQ substantially at the as-deposited value prior to oxide deposition by PECVD and planarization. Passivation and stabilization are effected by treating the as--deposited HSQ layer in a silane (SiH.sub.4) containing plasma.Type: GrantFiled: December 18, 1997Date of Patent: March 28, 2000Assignee: Advanced Micro Devices, Inc.Inventors: Robert C.

Patent number: 5973387Abstract: Leading and trailing metal features in a dense array of conductive lines bordering an open field are formed with side surfaces that gradually taper in the direction of the open field toward an underlying substrate. Each side surface bordering the open field is formed with a sufficient slope to reduce cracking of the subsequently deposited dielectric gap fill layer at high stress areas bordering the open field.Type: GrantFiled: December 18, 1997Date of Patent: October 26, 1999Assignee: Advanced Micro Devices, Inc.Inventors: Robert C.
