| 20090093338 | HYDRAULIC CONTROL UNIT - A hydraulic control system of a friction device where fail-safe is required is provided with one oil pressure switch and one pressure changeover valve. The pressure changeover valve is switched by auxiliary oil pressure based on an operation of the oil pressure control valve. When an auxiliary port communicates with an input port and the pressure changeover valve is switched to the filling determination side, the oil pressure switch is turned on and “filling determination” can be carried out. When the auxiliary port is disconnected from the input port, the pressure changeover valve is switched to the fail-safe determination side. The oil pressure switch is supplied with the same driving oil pressure as of the friction device and “fail-safe determination” can be carried out from the on/off state of the oil pressure switch. | 04-09-2009 |

| 20100204007 | METHOD FOR CONTROLLING AN AUTOMATIC TRANSMISSION OF A MOTOR VEHICLE - A method of controlling an automatic transmission of a vehicle in which a hold gear function is activated by a driver request and is deactivated independently of a return condition. To allow an effective, safe to operate, and comfortable use, the return condition depends on one of the following criteria or a useful combination of the same: a flexible time span, consideration of the vehicle stand still time; a rotational speed of the vehicle engine, or one or several parameters which correlate with the engine rotational speed, a new, the same, or a different drive request by the driver, a change in the operating condition of the vehicle, and a plausibility check occurring during the startup procedure. | 08-12-2010 |
| 20110118080 | TRANSMISSION HYDRAULIC CONTROL SYSTEM HAVING CLUTCH COMPENSATOR FEED OVERRIDE - A hydraulic control system in a transmission includes a source of pressurized hydraulic fluid and a compensator valve in communication with the source of pressurized hydraulic fluid and a torque transmitting device. The compensator valve is operable to allow communication of the hydraulic fluid from the source of pressurized hydraulic fluid to the torque transmitting device to release the torque transmitting device. A regulation valve is in communication with the source of pressurized hydraulic fluid and the torque transmitting device. The regulation valve is moveable between a first position that prevents the hydraulic fluid from communicating with the torque transmitting device and a second position that allows the hydraulic fluid to communicate with the torque transmitting device to engage the torque transmitting device. An override feature is operable to prevent the compensator valve from communicating the hydraulic fluid to the torque transmitting device when the torque transmitting device is engaged. | 05-19-2011 |
| 20110207578 | Harmonic Gear Multi-Turn Encoder - Various embodiments of harmonic gear multi-turn encoders are disclosed that provide the ability to accurately sense absolute rotational positions over a wide range of rotational counts. High gear reduction ratios in each stage of the multi-turn encoders permit very small size and volume encoders to be provided, thereby opening up many new applications for multi-turn encoders. In one embodiment, inductive means are employed to determine the number of revolutions a central shaft operably connected to an encoder module has turned. The inductive coils comprise emitter coils and receiver coils, which are operably associated with and opposed to corresponding encoder devices. The various embodiments of the harmonic gear multi-turn encoders disclosed herein are capable of operating under high temperature conditions and withstanding the effects of various environmental contaminants, and are also amenable to miniaturization and low cost manufacturing. | 08-25-2011 |
