Publication number: 20160380830Abstract: The disclosure is related to a method and a system for managing multiple devices within a network system. For the purpose of configuration or firmware synchronization for the devices within a network segment, the system allows an operator to optionally select the nodes operating as different roles such as a master, synchronization-source device, and slave. A selected device being the master is embedded with a web-based management mechanism, and therefore is remotely accessible. The management program provides a management interface in response to a management link. The management interface allows the operator to instruct the master to synchronize its configuration/firmware with the other selected nodes. Alternatively, through the master, one of the nodes is selected to be the synchronization-source device, and instructed to share its configuration to the other nodes. Through this management mechanism, the multiple nodes can be synchronized as applying the configuration, or/and firmware simultaneously.Type: ApplicationFiled: June 26, 2015Publication date: December 29, 2016Inventors: WEI JEN CHENG, MENG TSE CHEN

Patent number: 9333856Abstract: A device for controlling power to a vehicular differential speed controller is applied to control a differential speed controller inside a vehicle, and has an input voltage regulation circuit, a trigger circuit, a driving circuit and a relay. The input voltage regulation circuit converts an input voltage into an operating voltage and supplies the operating voltage to the trigger circuit. The trigger circuit generates a trigger signal after receiving a parking brake signal, such that the driving circuit activates the relay according to the trigger signal and supplies an output voltage to the differential speed controller. Accordingly, the present invention can automatically provide a sufficient power supply time to the differential speed controller to switch an operation state of a vehicle differential to a locked state when the vehicle power is switched off and the parking brake is activated.Type: GrantFiled: December 1, 2014Date of Patent: May 10, 2016Assignee: KWANG YANG MOTOR CO., LTD.Inventors: Wei-Jen Cheng, Shih-Chia Hsieh, Te-Feng Chen
