| Patent application number | Description | Published |
|---|---|---|
| 20080295492 | Injector cleaning system based on pressure decay - An injector cleaning system for use with an exhaust treatment device is disclosed. The injector cleaning system may have a supply of injection fluid and an injector configured to receive and inject the injection fluid. The injector cleaning system may also have a pressure sensor associated with the injector to generate a signal indicative of the pressure of the injection fluid supplied to the injector. The injector cleaning system may further have a controller in communication with the injector and the pressure sensor. The controller may be configured to determine a pressure decay rate of injection fluid supplied to the injector during a normal injection event based on the signal. The controller may be further configured to compare the determined pressure decay rate to an expected pressure decay rate, and supply cleaning fluid to the injector based on the comparison. | 12-04-2008 |

|---|---|---|
| 20090244478 | LENSES FOR THE CORRECTION OF PRESBYOPIA AND METHODS OF DESIGNING THE LENSES - The invention provides methods for designing contact lenses and contact lenses designed according to the method, which lenses provide an improved method for presbyopia correction compared to conventional lenses and methods. It is a discovery of the invention that improved performance and reduced design time can be obtained by using lens pairs that act synergistically to provide the lens wearer with good binocularity and consistent performance in near, intermediate and distance vision. | 10-01-2009 |
