Computer architecture allowing recycling of instruction slack time
A computer architecture suitable for out-of-order processors manages the problem of timing slack, in which an instruction completes before its clock cycle, by recycling that slack to allow the next succeeding instruction allowing that instruction to begin execution earlier. This recycling mechanism is enabled through the use of a transparent gating between execution units which allows data transfer before clock cycle boundaries and, in some cases, by aggressively issuing children instructions contemporaneously with their parent instruction after a grandparent instruction is issued. |

Control of voltage source converters
This application relates to methods and apparatus for control of voltage source converters. The control apparatus has a reference voltage generator that generates a voltage control signal as part of a voltage control loop. The reference voltage generator may be a DC voltage/power controller operated to regulate DC voltage or power and may generate the voltage control signal based on a feedback DC voltage/power signal and a defined set-point. An overcurrent controller generates a current control signal for modulating the voltage control signal to prevent an overcurrent. The overcurrent controller generates the current control signal as part of a control path that is independent from the voltage control loop. The DC voltage/power controller may thus directly generate a voltage reference and may act to keep the DC voltage substantially constant over the time scale of short term transients, with the overcurrent controller providing current limiting only when required. |

Low drop-out (LDO) voltage regulator with direct and indirect compensation circuit
A low drop-out (LDO) voltage regulator employs combined compensation methods for reduced capacitor area. Frequency compensation internal to a LDO voltage regulator is accomplished by introducing a metal-insulator-metal (MIM) compensation capacitor in series with a compensation resistor between an input to a second stage of the LDO voltage regulator and a regulator output. This achieves a good settling response over a wide range of load conditions at the expense of relatively large capacitor area. Alternatively, a metal-oxide semiconductor (MOS) compensation capacitor may be coupled between an intermediate node of a cascode circuit in a first stage of the LDO voltage regulator and the regulator output. This requires less capacitor area but exhibits instability at some corners. In combination, a good settling response over all corners may be achieved with stacked MIM/MOS capacitors occupying significantly less area than the MIM capacitor of the first method alone. |

In each method portion, travel times are ascertained. The fill level is ascertained based on the first travel time and/or based on the second travel time, to the extent that they approximately agree. Otherwise, it is assumed that such echo pulses concern extra-range echos. Thus, by means of the method of the invention, it can be assured for pulse radar-based fill-level measurements that extra-range echos do not result in erroneous fill level values. |

System and method for controlling pump performance in a transmission
A hydraulic system of a transmission having a controller and a variable displacement pump. The pump includes an inlet and outlet and is adapted to be driven by a torque-generating mechanism. The system also includes a lube circuit fluidly coupled to the pump. A lube regulator valve is disposed in the lube circuit, such that the lube regulator valve is configured to move between at least a regulated position and an unregulated position. The regulated position corresponds to a regulated pressure in the lube circuit. A pressure switch is fluidly coupled to the lube regulator valve and configured to move between a first position and a second position, where the switch is disposed in electrical communication with the controller. A solenoid is disposed in electrical communication with the controller and is controllably coupled to the pump to alter the displacement of the pump. |

Line pressure control method for dual-clutch transmission
A line pressure control method for a dual-clutch transmission (DCT), may include a hydraulic-pressure-decreasing operation of interrupting, by a controller, the supply of current to an electric oil pump and estimating a decrease in a line pressure using a line pressure model based on a pressure accumulator mounted in a hydraulic pressure line, a pump-driving operation of, when the estimated line pressure is equal to or less than a predetermined lower-limit value, driving, by the controller, the electric oil pump, and a hydraulic-pressure-increasing operation of determining, by the controller, the line pressure based on the current supplied to the electric oil pump and to determine whether the determined line pressure is equal to or greater than a predetermined upper-limit value. |

Hydraulic pressure control device and hydraulic pressure control method for vehicle
The present invention improves fuel efficiency of a vehicle and decreases a noise, by decreasing a margin value of a hydraulic pressure supplied to a hydraulic pressure control target and decreasing the hydraulic pressure supplied to the hydraulic pressure control target, when the vehicle is driven automatically. In a hydraulic pressure control device 1 for a vehicle that controls a line pressure or an operation pressure (hydraulic pressure) supplied to a clutch 40 or a transmission 41 (hydraulic pressure control target) provided in the vehicle, the hydraulic pressure control device 1 includes an operation pressure control unit 10 (hydraulic pressure setting device) that sets margin values α1 and α2 of the operation pressure (line pressure) supplied to hydraulic circuits 31 and 31 of the clutch 40 or the transmission 41, on the basis of a predetermined driving plan (refer to FIG. 2) in the case of driving the vehicle automatically. |

Method and device for training an automatically operating gear unit
A method for training an automatic gear unit of a two-wheeled vehicle and/or a device, as well as a two-wheeled vehicle having such a device modifies an existing characteristic map for the control of the gear unit based on the individual user information. Optionally, it is also possible to set up a characteristic map for the control of the gear unit with the aid of the method in that the user information is recorded during gear-change operations and utilized for further automatic gear-change operations. |

Ballscrew lubrication
A re-circulating ballscrew assembly comprises a plurality of balls. A ballnut has a ballnut body with a radially inner surface and a helical ballnut groove formed on the radially inner surface. A ballscrew is disposed within the ballnut, the ballscrew comprising a radially outer surface and a ballscrew groove formed on the outer surface, the ballscrew groove cooperating with the ballnut groove to define a helical raceway for the plurality of balls, the helical raceway having a start point and an end point. The ballscrew assembly comprises a return track for the plurality of balls, the return track disposed radially outward of the radially inner surface of the ballnut and connecting the start point and the end point of the helical raceway. The return track extends at least in part through an annular lubricant bath. |
