Patent number: 8676532Abstract: A fall detection device that is allowed to reduce the processing load put when making a determination using software, to reliably determine the start of a fall, and to make a fall prediction as necessary, and a magnetic disk drive and a portable electronic apparatus that each include the fall detection device are configured. Accelerations are obtained in three orthogonal axis directions (ax, ay, az), and an evaluation value is obtained with respect to each of the accelerations (ax, ay, az) on the basis of an evaluation function, by which an evaluation value is increased as the difference increases between accelerations (ax0, ay0, az0) at a steady time and accelerations (ax, ay, az) at a fall determination time, and whether a fall has started is determined on the basis of whether this evaluation value exceeds a predetermined value.Type: GrantFiled: March 19, 2010Date of Patent: March 18, 2014Assignee: Murata Manufacturing Co., Ltd.Inventor: Akihiko Shibata

Patent number: 8164847Abstract: By detecting that a differentiation value of the absolute value of acceleration is lower than a negative threshold value DAth1 in a negative direction from a first stage (S1: Stationary state) where the differentiation value of the absolute value of acceleration is approximately 0, it is considered that the stage is in a second stage (S2: Fall start state). When the absolute value of acceleration after that has become lower from a threshold value Ath1, it is considered that the fall detection device has entered a third stage (S3: Low gravity state). When the low gravity state has continued for a given time T3, it is considered that the stage is in a fourth stage (S4: Falling state), and a fall detection signal is output. Thus, the processing load when the determination is performed by software is reduced and the prediction of a fall can be performed.Type: GrantFiled: November 30, 2009Date of Patent: April 24, 2012Assignee: Murata Manufacturing Co., Ltd.Inventor: Akihiko Shibata

Publication number: 20110149431Abstract: A fall detection apparatus that detects values ax, ay, and az in accordance with acceleration in three mutually orthogonal axes (x, y, and z). Among these detected values, the fall detection apparatus determines values dxy and dzy which are the differences between the detected value for a reference axis, e.g., the y-axis, as well as the other detected values. A falling state signal is then generated when a preliminary determination state in which the determination values are within predetermined ranges continues for a predetermined time or longer.Type: ApplicationFiled: January 21, 2011Publication date: June 23, 2011Inventor: Akihiko Shibata
