20100233799 | INTEGRATED MICROFLUIDIC CONTROL EMPLOYING PROGRAMMABLE TACTILE ACTUATORS - Microfluidic devices having active features such as valves, peristaltic pumps, and mixing portions are fabricated to have a thin elastomeric membrane over the active features. The active features are activated by a tactile actuator external to the membrane, for example, a commercial Braille display. The display may be computer controlled, for example by simple text editor software, to activate individual Braille protrusions or a plurality of protrusions to actuate the active portions of the microfluidic device. Integral devices can incorporate the tactile actuators in a single device, but still external to the membrane. | 09-16-2010 |

20120101699 | BRAKE ASSIST FUNCTION - A method of controlling a vehicle having a transmission system, an engine system, and a braking system includes detecting a braking condition of the braking system. The braking condition is at least one of a brake temperature being above a predetermined brake temperature limit and a braking load being above a predetermined braking load limit. The method also includes detecting a second condition of at least one of the transmission system and the engine system. The method also includes determining whether the second condition satisfies predetermined criteria. Furthermore, the method includes detecting an absolute vehicle acceleration that is below a predetermined acceleration limit. Moreover, the method includes downshifting from a current gear to a lower gear to thereby cause engine braking when the braking condition is satisfied, the second condition satisfies the predetermined criteria, and the absolute vehicle acceleration is below the predetermined acceleration limit. | 04-26-2012 |
