Patent number: 10094306Abstract: Advanced combustion modes, such as PCCI, operate near the system stability limits. In PCCI, the combustion event begins without a direct combustion trigger in contrast to traditional spark-ignited gasoline engines and direct-injected diesel engines. The lack of a direct combustion trigger encourages the usage of model-based controls to provide robust control of the combustion phasing. The nonlinear relationships between the control inputs and the combustion system response often limit the effectiveness of traditional, non-model-based controllers. Accurate knowledge of the system states and inputs is helpful for implementation of an effective nonlinear controller. A nonlinear controller is developed and implemented to control the engine combustion timing during diesel PCCI operation by targeting desired values of the in-cylinder oxygen concentration, pressure, and temperature during early fuel injection.Type: GrantFiled: December 12, 2013Date of Patent: October 9, 2018Assignee: Purdue Research FoundationInventors: Gregory M. Shaver, Lyle E. Kocher, Carrie Hall, Daniel Van Alstine, Mark Magee

Patent number: 7512278Abstract: An array encoding system and method for use with high definition digital video data streams includes method and means for analyzing the incoming data stream, splitting the data stream in accordance with video complexity or other criteria, encoding each of the subsidiary data streams in accordance with a desired encoding standard, and combining the data streams to generate an output. The encoding system and method is particularly suited to encoding data streams to provide an output with is substantially consistent with the H.264 video communications standard. The system and method are scalable.Type: GrantFiled: April 7, 2004Date of Patent: March 31, 2009Assignee: Modulus Video Inc.Inventors: Mark Magee, Wayne Michelsen, Jean Dumouchel, Randall S. May, Peter Michael Emanuel, Robert S. Robinett

Patent number: 6169843Abstract: A method and apparatus for recording and playback of transport stream packets including multiplexed audio, video and other data streams. The transport streams may be generated in accordance with an MPEG-2 standard. In a record mode, an arrival timestamp is generated for each input transport packet to be recorded in a peripheral storage device. A given arrival timestamp indicates the arrival time of the corresponding transport packet in the recording system. Each of the transport packets are then stored with their corresponding arrival timestamps. The record mode may utilize a packet identifier (PID) decoder to perform packet filtering such that only incoming transport packets with selected PIDs are stored. In a playback mode, transport packets and corresponding arrival timestamps are retrieved from the storage device and the arrival timestamps are utilized to direct synchronous delivery of the transport packets to, for example, a decoder or a transport stream broadcast system.Type: GrantFiled: September 19, 1997Date of Patent: January 2, 2001Assignee: Harmonic, Inc.Inventors: Michael P. Lenihan, Sean C. Hart, Mark Magee, Brian Johnson

Patent number: 6074260Abstract: A reversible liferaft has an inflatable structure (10, 11, 12, 18, 19, 40) that supports a canopy providing a floor (14) and a roof (15) that lie in parallel planes. This makes the liferaft reversible which is a useful safety feature.Type: GrantFiled: March 11, 1998Date of Patent: June 13, 2000Assignee: Wardle Storeys (Safety & Survival Equipment) LimitedInventors: Anthony Roy Harris, Thomas George Scott, Mark Magee

Patent number: 6002687Abstract: A remultiplexer is disclosed for communicating plural programs. Each program comprises one or more elementary streams that are encoded in relation to a single common time base corresponding to the respective program. The communicated programs originate from plural input transport streams that each comprises plural transport packets. Each transport packet contains a packet identifier indicating the data contained therein. Within each transport stream, unique packet identifiers are assigned to each elementary stream of each program. The data of each elementary stream is only contained in transport packets having a corresponding packet identifier. Each input transport stream contains time stamps for reconstructing the single program time base corresponding to each program conveyed therein. The remultiplexer has a data link module which receives the plural input transport streams. The data link module also selectively extracts transport packets from the received input transport streams.Type: GrantFiled: November 10, 1998Date of Patent: December 14, 1999Assignee: Divicon, Inc.Inventors: Mark Magee, Brian Johnson, Tom Lookabaugh, Nolan Daines
