Patent number: 9745684Abstract: A washing machine having a balancer and a control method thereof which achieve correct communication between a controller and a balancing module such that a balancing module is correctly shifted to a target position. The control method of the washing machine includes measuring a first time between position detection time points of the balancing modules during rotation of the rotary tub when the plurality of balancing modules is in a static mode, measuring a second time between position detection time points of the balancing modules during rotation of the rotary tub when any one of the balancing modules is shifted by a predetermined distance through a movement command, and confirming a relationship between a module ID of any one of the balancing modules and a communication ID of the movement command through a relative variation of the second time with respect to the first time.Type: GrantFiled: August 30, 2013Date of Patent: August 29, 2017Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Ji Eun Lee, Yoon Sup Kim, Su Ho Jo, Kwan Joo Myoung, Awata Hiroshi

Patent number: 9448008Abstract: An air conditioner is provided. The air conditioner includes at least one outdoor unit, a plurality of indoor units, and at least one remote controller to receive operation commands for the plural indoor units. One of the plural indoor units may be selected as a power-supplying indoor unit to supply electric power to the at least one remote controller, based on voltage values of electric power to be supplied from the plural indoor units to the at least one remote controller. The selected indoor unit supplies electric power to the at least one controller. The air conditioner enables a supply of electric power with a sufficiently high voltage to a remote controller by supplying electric power to the remote controller by one indoor unit exhibiting a highest voltage value of electric power to be supplied to the remote controller, as compared to other indoor units.Type: GrantFiled: January 24, 2014Date of Patent: September 20, 2016Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Ji Eun Lee, Su Ho Jo, Kwan Joo Myoung, Awata Hiroshi, Yuodo

Patent number: 9140463Abstract: An indoor unit performs a control operation to not supply power to a load device through a power/communication line simultaneously with other indoor units. An air conditioning system may includes an indoor unit including a microcomputer to output a power application signal to supply power to a load device through a power/communication line, and a duplicate power application prevention unit to interrupt the power application signal from the microcomputer when the power is simultaneously applied to the power/communication line by a different indoor unit, to prevent the power from being duplicately applied to the power/communication line.Type: GrantFiled: May 25, 2011Date of Patent: September 22, 2015Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Su Ho Jo, Kwan Joo Myoung, Awata Hiroshi, O Do Ryu
