Abstract: Methods for identifying encrypted content in ones of a plurality of encrypted data files in a library of encrypted files without decrypting the data files utilize crowd sourcing for content identification. A method includes selecting, by a computer, content titles for presenting with ones of identifiers for the data files in a data structure. Each of the identifiers includes a hash of metadata for one of the data files and the content titles include a character string that identifies each file's content. The user selection data identifies the content titles that correspond to the data files. The computer determines which content titles satisfy a minimum confidence threshold for associating with one of the identifiers, based on a quality or quantity of the multiple independent clients supplying the user selection data. An apparatus for performing the method includes a memory holding instructions for performing steps of the method as summarized above.

Abstract: A dual-clutch transmission assembly where engine torque is split between first and second shafts. Torque is supplied to the first shaft by a first clutch and torque is supplied to the second shaft by a second clutch. A first gearset is carried on the first shaft and a second gearset is carried on the second shaft. The first gearset includes a primary first gear and the second gearset includes a duplicate first gear. The first and second shafts receive torque from a transmission input shaft in response to contemporaneous engagement of the primary first gear, the duplicate first gear, and the first and second clutches, which can be used during vehicle launch to split the torque applied to the first and second clutches. Both the primary first gear and duplicate first gear meshingly engage first and second counter shaft gearsets, which are rotatably coupled to a transmission output shaft.

The clutch pack includes a primary backing plate, a reaction plate, first and second friction plates disposed between the backing plate and the reaction plate, and a secondary backing plate disposed between the first and second friction plates.

In the low torque state, the secondary backing plate cannot move longitudinally toward the primary backing plate beyond a locked position. In the high torque state, the secondary backing plate can move beyond the locked position.

Abstract: A clutch assembly that is less prone to overheating is disclosed. The clutch assembly includes a clutch housing, a shaft, and a clutch pack. The clutch pack includes a first apply plate, a second apply plate, a plurality of friction plates, and a plurality of reaction plates. The clutch assembly further includes a first actuator and a second actuator. The first actuator applies pressure to the first apply plate in a first direction to move the first apply plate toward the second apply plate. The second actuator applies pressure to the second apply plate in a second direction to move the second apply plate toward the first apply plate. The first direction is opposite the second direction such that the first and second actuators apply pressure to the clutch pack in opposing directions. This reduces localized temperature spikes in the clutch pack.

Abstract: A fuel pump assembly including a fuel pump and a variable drive mechanism is provided. The fuel pump has a pump input shaft rotatably coupled to an impeller. The variable drive mechanism has a drive input shaft that receives torque from the engine of a vehicle and a drive output shaft that is rotatably coupled to the pump input shaft. The variable drive mechanism further comprises a planetary gearset interconnecting the drive input shaft and the drive output shaft. The planetary gearset has a variable gear ratio that varies rotational speed of the drive output shaft and therefore the pump input shaft relative to the rotational speed of the drive input shaft. Accordingly, the rotational speed of the pump input shaft and thus the volume flowrate of the fuel pump can be adjusted for any given engine speed to minimize pump related losses.

Abstract: A method is described for controlling a solenoid-operated fluid valve having an output hydraulic pressure that varies in accordance with an input solenoid control current delivered from a drive circuit. A model is provided characterizing the plant dynamics of the solenoid-operated fluid valve and the drive circuit where the model is dependent on at least one operating parameter. The method, during operation, involves measuring the value of the operating parameter and adjusting based on the measured operating parameter value one or more gain constants to be used in a selected control strategy. The model is used in adjusting the gains. Finally, the method involves determining a required solenoid control current according to the control strategy with the now dynamically-adjusted gain constants. The control strategy may be a PI control strategy. The model-based system allows easy migration of the general control strategy to different hardware configurations by developing target system specific data for the model.

Abstract: A vehicle automatic speed change power transmission control includes a control arrangement with overshoot/undershoot protection logic. The control is used with an electro-hydraulic pressure control module featuring a linear solenoid, and which supplies a hydraulically-actuated clutch configured to effect gear changes. The overshoot/undershoot protection logic is configured to detect when a commanded increase/decrease clutch pressure satisfies a clutch pressure threshold and to then activate the protection logic. Once the protection logic is activated, large command pressures increases/decreases are implemented in a series of stages having variable gains. The first stage has an aggressive gain and achieves 50-80% of the commanded clutch pressure. The second stage has a reduced gain and achieves 90% of the commanded clutch pressure. The third stage has a still further reduced gain and achieves about 100% of the commanded clutch pressure.
