Publication number: 20130268350Abstract: Systems and methods for optimizing viral marketing efforts are disclosed in which a trial a viral marketing trial program is presented to a user. The viral marketing trial program includes a user incentive as well as a plurality of user tasks that needs to be completed to receive the user incentive. One or more user reactions to the plurality of user tasks are monitored; user feedback in accordance with the one or more user reactions is collected, the user feedback is analyzed using one or more metrics and the viral marketing trial program is adjusted in accordance with the analyzed user feedback.Type: ApplicationFiled: April 8, 2013Publication date: October 10, 2013Inventors: Ryan Michael Koonce, James Newton Calhoun, David Allen Bell, Sage Bray

Patent number: 8417558Abstract: A computer implemented method of improving the performance of a viral marketing program comprises exposing, via a computer network, a first offered incentive to a first plurality of users. A first consumer viral marketing action is to be completed to receive the first incentive. First data indicative of the first plurality of users' progress toward achieving the first action is collected thereby providing a likelihood of the first incentive obtaining an objective. A second incentive is exposed to a second plurality of users. A second consumer viral marketing action is to be completed to receive the second incentive. Second data indicative of the second plurality of users' progress toward achieving the second marketing action is collected thereby providing a likelihood of the second incentive obtaining the objective. The first and second data is compared using a metric to identify which incentive is more likely to obtain the objective.Type: GrantFiled: March 19, 2012Date of Patent: April 9, 2013Assignee: StrongMail Systems, Inc.Inventors: Ryan Michael Koonce, James Newton Calhoun, Jr., David Allen Bell, Sage Bray

Publication number: 20100024378Abstract: A gas turbine engine system is provided. The gas turbine engine system includes a gas turbine engine and an exhaust gas conditioning system. The gas turbine engine includes at least one combustion chamber and at least one turbine downstream from the combustion chamber. The combustion chamber is coupled in flow communication to a source of hydrocarbonaceous fuel and to a source of oxygen. The gas turbine engine is operable with a working fluid that is substantially nitrogen-free. The exhaust gas conditioning system is coupled between a discharge outlet of the gas turbine engine and an inlet of the gas turbine engine.Type: ApplicationFiled: July 30, 2008Publication date: February 4, 2010Inventors: John Frederick Ackermann, Matthew Timothy Franer, Randy Lee Lewis, David Allen Bell, Morris Dee Argyle, Brian Francis Towler

Publication number: 20100024433Abstract: A gas turbine engine system is provided. The gas turbine engine system includes a gas turbine engine, an exhaust gas conditioning system, and a sequestration chamber. The gas turbine engine includes at least one compressor, at least one combustion chamber downstream from the compressor, and at least one turbine downstream from the combustion chamber. The combustion chamber is coupled in flow communication to a source of hydrocarbonaceous fuel and to a source of oxygen. The gas turbine engine is operable with a working fluid that is substantially nitrogen-free. The exhaust gas conditioning system is coupled between a discharge outlet and an inlet of the gas turbine engine. The exhaust gas conditioning system receives all of the exhaust discharged from the gas turbine engine.

Patent number: 6400308Abstract: A radar system is described for use in vehicular applications. The radar system is particularly suited to backup warning systems and lane-change warning systems. The radar minimizes many of the problems found in the prior art by providing programmable delays and programmable gain. The radar uses a range search algorithm to detect and sort targets at various ranges within the field of view of the radar. Each target range corresponds to a particular delay and gain setting. The radar searches for targets at the various ranges by running a target search algorithm. For each target range, the search algorithm causes the proper time delay and gain setting. Targets within the selected range are detected and catalogued. Speed of the targets is obtained through Doppler processing. A display is used to warn the driver of the vehicle of the presence of targets at the various ranges. The warning may be visual and/or audible.Type: GrantFiled: October 9, 1998Date of Patent: June 4, 2002Assignee: Amerigon Inc.Inventors: David Allen Bell, Jimmy Moon Kan Li, Roger Taur, Jess Delacueva
