| 20100171569 | ACTIVE DOUBLE OR MULTI GATE MICRO-ELECTRO-MECHANICAL DEVICE WITH BUILT-IN TRANSISTOR - The present invention exploits the combination of the amplification, provided by the integration of a FET (or any other active device with two or more terminals), with the signal modulation, provided by the MEM resonator, to build a MEM resonator with built-in transistor (hereafter called active MEM resonator). In these devices, a mechanical displacement is converted into a current modulation and depending on the active MEM resonator geometry, number of gates and bias conditions it is possible to selectively amplify an applied signal. This invention integrates proposes to integrate transistor and micro-electro-mechanical resonator operation in a device with a single body and multiple surrounding gates for improved performance, control and functionality. Moreover, under certain conditions, an active resonator can serve as DC-AC converter and provide at the output an AC signal corresponding to its mechanical resonance frequency. | 07-08-2010 |

| 20100226762 | Structural members in a pedestal array - A turbine engine component has a flow path wall and a support wall. The turbine engine component has at least one cooling compact heat exchanger. Each cooling compact heat exchanger has a pedestal array and at least one structural member within the pedestal array for preventing modal crossing in operation range, for preventing panel bulging, and/or for connecting the flow path wall to at least one outer diameter support structure. | 09-09-2010 |

| 20110190088 | SELF-CONTAINED HYDRAULIC TORQUE MODULATING DEVICE - A torque modulating coupling device for operatively linking two shafts has a clutch and a piston disposed in a case. The piston selectively applies force to the clutch in response to hydraulic pressure, and a keyed feature adapted to couple with a corresponding keyed feature associated with at least one of the shafts. The coupling device can be formed with two cases that form an enclosure for the clutch and the piston, trapping the piston forces between the cases. This embodiment allows the device to also act as an axle housing cover. In another embodiment, the case is designed to bolt directly to an axle housing cover, trapping piston forces between the case and the cover. | 08-04-2011 |

| 20080230295 | IDLE-ABLE POWER TRANSFER UNIT - A vehicle driveline comprising a primary drive system including at least one primary drive wheel and an auxiliary drive system including at least one auxiliary drive wheel is disclosed. The vehicle driveline may further comprise a system for idling the auxiliary drive system. The system may include at least one wheel disconnect device for selectively connecting and disconnecting the auxiliary drive wheel from the auxiliary drive system and a power transfer unit for selectively engaging and disengaging the auxiliary drive system from the primary drive system. The power transfer unit may include a multi-plate clutch in series with a dog clutch. | 09-25-2008 |
| 20100147644 | IDLE-ABLE AUXILIARY DRIVE SYSTEM - A power transfer unit (PTU) for a motive device includes an outer housing and a torque transferring clutch. The PTU also includes a piston housing located between the outer housing and the torque transferring clutch, and a piston in the piston housing. The piston is arranged to provide actuation forces to the torque transferring clutch, and to restrict reaction forces back to the piston housing. | 06-17-2010 |
| 20110127135 | Idle-Able Auxiliary Drive System - A power transfer unit for a motive device comprises an outer housing, an inner housing, and a torque transferring clutch. A piston housing is located between the outer housing and the torque transferring clutch. A piston is located in the piston housing. The piston is configured to provide actuation forces to the torque transferring clutch. And, when the torque transferring clutch receives the actuation forces, the torque transferring clutch causes the inner housing to rotate. | 06-02-2011 |
