Patent number: 8918241Abstract: 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.Type: GrantFiled: July 18, 2013Date of Patent: December 23, 2014Assignee: Agait Technology CorporationInventors: Tien-Chen Chen, Kai-Sheng Lee

Patent number: 8869499Abstract: 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 the paper-dispensing module.Type: GrantFiled: May 1, 2012Date of Patent: October 28, 2014Assignee: Tien-Chen ChenInventors: Tien-Chen Chen, Wei-Han Chen

Publication number: 20140152835Abstract: 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.Type: ApplicationFiled: March 14, 2013Publication date: June 5, 2014Applicant: AGAIT TECHNOLOGY CORPORATIONInventors: TIEN-CHEN CHEN, YANG-TZUNG LIEN, WEI-HAN CHEN, MING-FENG HSUEH, MU-CHE LIN

Patent number: 8660736Abstract: 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.Type: GrantFiled: August 7, 2012Date of Patent: February 25, 2014Assignee: Agait Technology CorporationInventors: Tien-Chen Chen, Kai-Sheng Lee, Peng-Sheng Chen

Publication number: 20140005873Abstract: An autonomous mobile device system includes a plurality of magnetic components and an autonomous mobile device. The magnetic components are adapted to be arranged on a surface in a space-apart manner and produce a magnetic field serving as a virtual boundary on the surface. The autonomous mobile device is configured to move on the surface, and includes a housing, a magnetic sensor for detecting the magnetic field, and a motion control module for controlling movement of the autonomous mobile device. The motion control module is operable in a first movement mode, in which the autonomous mobile device is restrained from crossing the virtual boundary when the magnetic sensor detects the magnetic field.Type: ApplicationFiled: March 15, 2013Publication date: January 2, 2014Applicant: AGAIT TECHNOLOGY CORPORATIONInventors: Tien-Chen CHEN, Yang-Tzung LIEN, Tian-Rong XIE

Patent number: 8525975Abstract: 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.Type: GrantFiled: November 30, 2010Date of Patent: September 3, 2013Assignee: Agait Technology CorporationInventors: Tien-Chen Chen, Dah-Prong Lai
