| 20110086733 | SPORTS TARGET DEVICE AND METHOD - An interactive sports target device is designed specifically to be suspended on the inside of a net attached to a goal. The target device emits an audible signal when impacted by a projectile such as a ball, puck or the like. The target device is light in weight to avoid deforming the net and can be easily attached or detached to the net in less than 30 seconds. The target device is reversible and can include both a front and rear with contrasting colors or designs. Both mechanical and electronic target devices are shown which provide a loud audible sound when struck by a projectile. Advanced electronic versions contain a programmable processor. | 04-14-2011 |

| 20080262712 | METHODS AND SYSTEMS FOR POWERTRAIN OPTIMIZATION AND IMPROVED FUEL ECONOMY - The technology described herein provides methods and systems for powertrain optimization and improved fuel economy including multiple displacement engine modeling and control optimization, automotive powertrain matching for fuel economy, cycle-based automotive shift and lock-up scheduling for fuel economy, and engine performance requirements based on vehicle attributes and drive cycle characteristics. Also provided is a reverse tractive road load demand simulation algorithm used to propagate a reverse tractive road load demand and a corresponding component torque and speed, derived from a vehicle speed trace, in a reverse direction through a powertrain system. Also provided is a dynamic optimization algorithm. The dynamic programming algorithm is applied to a matrix of fuel flow rates to find the optimal control path that maximizes the powertrain efficiency over a cycle. | 10-23-2008 |
| 20080288146 | SYSTEMS AND METHODS FOR DETECTING AND REDUCING HIGH DRIVELINE TORSIONAL LEVELS IN AUTOMOBILE TRANSMISSIONS - The present disclosure provides systems and methods to detect and reduce any high driveline torsional levels, such as due to the cylinder deactivation in variable displacement system engines or aggressive lock-up strategies for fuel efficiency, in automobile transmissions. The present disclosure utilizes a controller in an automobile to operate a computationally thrifty method for quickly detecting noise and vibration disturbances in the transmission. This quick detection enables fuel economic calibrations that aggressively reduce the disturbances by controlling slip in a launch device of the transmission. As problem disturbances arise, they are detected before occupants notice objectionable behavior. Once detected, the disturbances are reduced, such as by increasing launch device slip, which effectively intercepts the objectionable disturbances before they are transferred through the entire drivetrain. The present disclosure can also apply to launch devices in Dual Clutch Transmissions and Electronically-controlled Manual Transmissions. | 11-20-2008 |
