20150364654 | SEMICONDUCTOR LIGHT EMITTING DEVICE WITH LIGHT EXTRACTION STRUCTURES - Structures are incorporated into a semiconductor light emitting device which may increase the extraction of light emitted at glancing incidence angles. In some embodiments, the device includes a low index material that directs light away from the metal contacts by total internal reflection. In some embodiments, the device includes extraction features such as cavities in the semiconductor structure which may extract glancing angle light directly, or direct the glancing angle light into smaller incidence angles which are more easily extracted from the device. | 12-17-2015 |

20080259980 | Semiconductor Light Emitting Device Including Oxide Layer - A device includes a semiconductor structure comprising a III-nitride light emitting layer disposed between an n-type region and a p-type region. The semiconductor structure is grown over an oxide layer disposed between first and second III-nitride layers. The oxide layer may at least partially relieve the strain in the light emitting layer by increasing the in-plane lattice constant of the template on which the light emitting layer is grown. The oxide layer may be formed by growing an AlInN layer in the device, etching a trench to expose the AlInN layer, then oxidizing the AlInN layer. | 10-23-2008 |

20100116367 | ON-OFF VALVE IN A FUEL DELIVERY MODULE AND METHOD FOR RETROFITTING THE FUEL DELIVERY MODULE - The control valve of the invention has two inlets and one outlet, where a first inlet and the outlet are provided at the front side and the second inlet at the circumference of the control valve. The inlets end in a valve chamber having a fluid connection to the outlet via a valve seat opening. The valve seat opening has a valve seat that can be closed with a valve body that is moveably arranged in a control valve. The outlet extends into the valve chamber with a valve seat section. A radial gap is provided between the valve seat section and a peripheral wall of the valve chamber. The control valve is suitable to be retrofitted to a reservoir pan in order to secure the fuel supply of a single-stage delivery assembly in each operational state when a two-stage delivery assembly is replaced by a single-stage delivery assembly. The control valve comprises a separate valve housing, which is designed such that it can be inserted and fastened in a cylindrical opening. | 05-13-2010 |

20130333904 | Machine Tool and Control Method - A machine tool with a tool holder which is equipped to mount a tool, such as a chiseling tool, moveably along a movement axis. A striking mechanism contains a primary drive, arranged around the movement axis, containing at least one magnetic coil. The striking mechanism has a striker and an anvil arranged within the magnetic coil on the movement axis in sequence in the impact direction. The anvil protrudes at least partially into the magnetic coil. In addition, the striking mechanism can have an air spring affecting the striker in the impact direction. A controlled power source forms an electrical circuit in which a current flows, controlled at a target value, from the power source and into at the at least one magnetic coil during an acceleration phase. A controller ends the acceleration phase when a change, typical for an impact, is detected in the current flowing in the magnetic coil or a change, typical for an impact, is detected in a control variable of a control circuit of the power source. | 12-19-2013 |

20130333909 | MACHINE TOOL - A machine tool is disclosed. A magneto-pneumatic striking mechanism has a primary actuator arranged around an axis of movement and includes a first magnetic coil and a second magnetic coil. The striking mechanism has, on the axis of movement within the magnetic coils, a striker and a die. Furthermore, the striking mechanism has an air spring acting on the striker in a direction of impact. The air spring may be entirely or partially within the first magnetic coil. The air spring has a ventilation opening that is open to the environment if the striker is less than 10% of its stroke away from the die, and otherwise the ventilation opening is closed. An exchange of air with the environment is therefore only possible when the striker is near the die or is near the impact position. | 12-19-2013 |

20110162860 | CONTROL METHOD FOR A HAND-OPERATED POWER TOOL AND POWER TOOL - A hand-operated rotary power tool and a method of operating the tool is disclosed. The tool has an electric motor for driving a rotary tool, a sensor device for detecting a blockade of the tool and a triggering device, which, in response to a blockade detected by the sensor device, reverses a direction of rotation of the electric motor prior to the blockade for a predetermined duration and immediately following induces the electric motor to again rotate in the direction of rotation. | 07-07-2011 |
20120055689 | HANDHELD POWER TOOL - A handheld power tool is disclosed. The handheld power tool has a drive oscillating along a working axis and a vibration damper. The vibration damper has a mass element suspended in a spring mechanism. The spring mechanism acts with a first spring stiffness and acts with a second spring stiffness. The first spring stiffness is different from the second spring stiffness. | 03-08-2012 |
20140311763 | PERCUSSION MECHANISM - A percussion mechanism includes a first shaft and a second shaft. One or more vanes are fastened to the first shaft. The vanes are arranged so as to be rotatable in a chamber of the second shaft. The chamber is filled with a magnetorheological fluid. A magnetic field source on the second shaft generates a magnetic field that is spatially modulated in the circumferential direction inside the chamber. | 10-23-2014 |
20140326474 | HAND-HELD POWER TOOL - A hand-held power tool has a motor, a tool holder, and a percussion mechanism disposed between the motor and the tool holder in the drive train. The percussion mechanism includes a first shaft and a second shaft. A magnetically conductive ring gear is connected to the first shaft. An inner wall of the ring gear is eccentric to an axis of the second shaft. A magnetically conductive impeller is connected to the second shaft and is arranged to rotate within the ring gear. The impeller is spaced from the ring gear by a first air gap in a first position while being spaced from the ring gear by a second air gap in a second position, the first air gap being smaller than the second one. A magnet array is arranged coaxially to the second shaft. A magnetorheological fluid fills a cavity between the ring gear and the impeller. | 11-06-2014 |
