Patent number: 10191075Abstract: An apparatus to detect a direction or velocity of a movement of equipment by using a single sensor. The apparatus includes a conversion unit that converts sensed information obtained from the single sensor into a voltage value corresponding to the movement of the equipment, a determination unit that determines whether one of a first interrupt and a second interrupt occurs, the first interrupt occurring when the converted voltage value reaches a threshold value and the second interrupt occurring when a preset amount of time passes from a time when the single sensor starts operating, and a calculation unit that calculates one of the direction and the velocity of the movement of the equipment by using voltage information at time s when the first interrupt or the second interrupt occurs and voltage information at a predetermined time before the times when the first interrupt or the second interrupt occurs.Type: GrantFiled: August 15, 2013Date of Patent: January 29, 2019Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Dong-eui Shin, Myung-won Park, Jae-heung Park, Ki-oh Jung
