20150236158 | METHOD FOR FABRICATING SEMICONDUCTOR DEVICE, AND SEMICONDUCTOR DEVICE MADE THEREBY - A method for fabricating a semiconductor device, and a semiconductor device made with the method are described. In the method, a cavity is formed in a substrate, a first epitaxy process is performed under a pressure higher than 65 torr to form a buffer layer in the cavity, and a second epitaxy process is performed to form a semiconductor compound layer on the buffer layer in the cavity. In the semiconductor device, the ratio (S/Y) of the thickness S of the buffer layer on a lower sidewall of the cavity to the thickness Y of the buffer layer at the bottom of the cavity ranges from 0.6 to 0.8. | 08-20-2015 |

20120026481 | DETECTOR DEVICE AND MOBILE ROBOT HAVING THE SAME - A detector device includes a detector module and a lens module. The detector module includes an optical emitter and a photon detector spaced apart from the optical emitter. The lens body includes a first light-transmissive surface, a second light-transmissive surface, and a third light-transmissive surface. The optical emitter is operable to emit a light beam passing through the first light-transmissive surface and the second light-transmissive surface toward a surface so as to define a field of emission on the surface. The photon detector is aligned with the first and third light-transmissive surfaces so as to define a field of view on the surface. An extent of overlap between the field of view and the field of emission varies in accordance with a distance between the optical emitter and the surface. | 02-02-2012 |

20120279188 | MOWING MACHINE - A mowing machine includes a cutting unit, a conveying unit for conveying grass clippings away from the cutting unit, and a packing unit including a paper-rolling module and a paper-dispensing module. The paper-rolling module defines an accommodation space for collecting grass clippings from the conveying unit, and includes scrolling axles spaced apart from each other by a gap, and movable between an opened position, where the gap has a predetermined width for allowing passage of the grass clippings from the conveying unit through the gap into the accommodation space, and a closed position, where the scrolling axles rotate to pack the grass clippings with the paper dispensed from said paper-dispensing module. | 11-08-2012 |
20130124031 | Autonomous Mobile Device and Method for Navigating the Same to a Base Station - A method of navigating an autonomous mobile device to a base station is provided. In the method, when a detector detects a navigating signal sent out by the base station, the mobile device rotates in a first direction until the detector fails to detect the navigating signal, and a first time point is set at this time. Then, the mobile device rotates in a second direction opposite to the first direction until the detector fails to detect the navigating signal, and a second time point is set at this time. Afterward, the mobile device rotates in the first direction by a time computed based on the first and second time points to make the detector face the base station, and then, moves toward a direction pointed by the detector. | 05-16-2013 |

20140121876 | AUTONOMOUS MOBILE DEVICE AND OPERATING METHOD FOR THE SAME - An autonomous mobile device is configured to move on a surface provided with a base station thereon, and is operated in one of a work state and return state. In the work state, the autonomous mobile device is operable to plot a movement route along which the autonomous mobile device moves, and is operable to adjust the movement route upon presence of an obstacle. In the return state, the autonomous mobile device is operable to plot a returning route on the surface from the current position to the base station, and to move along the returning route to the base station. | 05-01-2014 |
20140152835 | REMOTE MONITORING SYSTEM AND METHOD FOR OPERATING THE SAME - A remote monitoring system and a method for operating the same are revealed. The system gets monitoring images by a camera module of an automatic movable device. Then the monitoring images are output to a cloud storage device through a network module of the automatic movable device. A user at the remote end can receive and display the monitoring devices from the cloud storage device through the network or perform feedback control by a browsing device such as handheld electronic device or computer. Thus household appliances are integrated with cloud and other information media products to provide household monitoring function. | 06-05-2014 |

20080229526 | System for cleaning a wafer - A system for cleaning a wafer. At least one first chuck roller is connected to a first roller base and includes a first annular groove. A second roller base opposes the first roller base. At least one second chuck roller is connected to the second roller base and includes a second annular groove. A sensing chuck roller is connected to the second roller base and includes a third annular groove corresponding to the first and second annular grooves. A cleaning member covers the third annular groove. A circumferential edge of the wafer is positioned in the first and second annular grooves and abuts the cleaning member. The first and second chuck rollers rotate the wafer, enabling the circumferential edge thereof to rub against the cleaning member. | 09-25-2008 |
