Patent number: 10519876Abstract: Methods and controllers are described that facilitate the determination of an operational skip fire firing fraction for an engine based at least in part noise levels and/or vehicle vibration levels that are not induced by engine operation. In some embodiments, the firing fraction is determined based at least in part of noise or vibrations associated with road roughness and/or cabin noise levels.Type: GrantFiled: July 13, 2018Date of Patent: December 31, 2019Assignee: Tula Technology, Inc.Inventors: Vijay Srinivasan, Louis J.

Publication number: 20180328292Abstract: A system and method for dynamically varying an amount slippage of a Torque Converter Clutch (TCC) provided between an engine and a transmission of a vehicle in response to non-powertrain factors. By varying a slippage output signal, the amount of TCC slippage between the engine and the transmission can be adjusted. Small amounts of slippage, relative to large amounts of slippage, provide (a) improved vehicle fuel economy, but (b) induce more powertrain noise and vibration in the vehicle cabin. By dynamically adjusting the slippage, a tradeoff between improved fuel economy vs. a satisfying driver experience can be realized.Type: ApplicationFiled: July 13, 2018Publication date: November 15, 2018Inventors: Vijay SRINIVASAN, Louis J. SERRANO, Siamak HASHEMI, Robert S. BAILEY, Geoffrey ROUTLEDGE

Publication number: 20180156692Abstract: A variety of methods, diagnostic modules and other arrangements for detecting air induction faults during operation of an internal combustion engine are described. In some embodiments, the intake manifold pressure is monitored with the intake pressure being read for each induction opportunity. Induction faults may be detected based at least in part on a comparison of the manifold pressure readings for sequential induction opportunities. In some embodiments, an induction fault is identified when the difference between the manifold pressure associated with an induction opportunity and the immediately preceding induction opportunity exceeds an induction fault threshold.Type: ApplicationFiled: January 16, 2018Publication date: June 7, 2018Inventors: Shikui Kevin CHEN, Allan J.

Patent number: 9891137Abstract: A variety of methods and arrangements for detecting failure of the commanded air induction in an internal combustion engine are described. In some embodiments, the intake manifold pressure is monitored. An air induction event generates a fluctuation in the intake manifold pressure, which is recorded. The signal is processed through a diagnostic filter to help determine whether the actual induction matched the commanded induction. In other embodiments, measured crankshaft acceleration is compared with estimated crankshaft acceleration. If the two quantities differ by a threshold amount an induction fault is detected. The two detection methods may also be combined. The describe approaches are particularly well suited for use in engines operating in a skip fire mode with cylinder deactivation and/or a dynamic firing level modulation mode.Type: GrantFiled: July 3, 2017Date of Patent: February 13, 2018Assignee: Tula Technology, Inc.Inventors: Shikui Kevin Chen, Allan J.

Patent number: 9150956Abstract: Aluminum or aluminum alloy sputter targets and methods of making same are provided. The pure aluminum or aluminum alloy is mechanically worked to produce a circular blank, and then the blank is given a recrystallization anneal to achieve desirable grain size and crystallographic texture. A 10-50% additional strain is provided to the blank step after the annealing to increase the mechanical strength. Further, in a flange area of the target, the strain is greater than in the other target areas with the strain in the flange area being imparted at a rate of about 20-60% strain. The blank is then finished to form a sputtering target with desirable crystallographic texture and adequate mechanical strength.Type: GrantFiled: July 26, 2013Date of Patent: October 6, 2015Assignee: Tosoh SMD, Inc.Inventors: Weifang Miao, David B.

Patent number: 8037727Abstract: A non-planar sputter target having differing crystallographic orientations in portions of the sputter target surface that promote more desirable deposition and density patterns of material sputtered from the target surface onto a substrate. A closed dome end of the sputter target is comprised of a first crystallographic orientation and sidewalls of the sputter target are comprised of a crystallographic orientation different from that of the dome. The sputter target is formed, preferably by hydroforming or other metal working techniques, in the absence of annealing. The hydroforming manipulations result in the different crystallographic orientations while minimizing, or ideally omitting, the application of heat. Quick and cost effective non-planar sputter targets that are easily repeatably producable are achievable as a result.Type: GrantFiled: May 29, 2009Date of Patent: October 18, 2011Assignee: Tosoh SMD, Inc.Inventors: Robert S.
