Personalization of automated vehicle control
Vehicles feature various forms of automated driving control, such as speed control and braking distance monitoring. However, the parameters of automated control may conflict with the user driving behaviors of the user; e.g., braking distance maintained with respect to a leading vehicle may seem overcautious to users who prefer shorter braking distances, and unsafe to users who prefer longer braking distances. Presented herein are techniques for controlling vehicles according to the user driving behaviors of users. While a user operates a vehicle in a driving context, a device monitors various driving features (e.g., acceleration or braking) to determine various user driving behaviors. When requested to control a driving feature of the vehicle, a controller may identify the user driving behaviors of the user in the driving context, and control the driving features according to the user driving behaviors, thus personalizing automated driving to the preferences of the user. |

Electric pulse tool
An electric pulse tool delivers torque in pulses on an output shaft of the electric pulse tool. The electric pulse tool includes an electric motor with a rotor and a gear arrangement adapted to drive the output shaft. The electrical pulse tool is operative, for each period, to control the speed of the rotor until a play in the gear arrangement is determined to be closed and the gear arrangement starts to move the output shaft. |

Dowel basket assembly machine
A dowel basket assembly apparatus includes a jig table rotationally supported on a bearing assembly, which supports a table top assembly having arms extending radially outwardly and supporting first, second and third jig table bases. The bases move through first, second and third stations by rotating the assembly. First jig table is positioned at first station, second jig table at second station, and third jig table at third station. Rods are located in receptacles on first jig table base at first station. Simultaneously, rods are welded to form a dowel basket on second jig table base at second station. Simultaneously, a welded dowel basket is unloaded from third jig table base at third station. After completion of the steps of locating, welding and retrieving, the apparatus is rotated to advance the jig tables to the next station. |
