Fall detection for elderly and patient has been an active research topic due to that the healthcare industry has a big demand for products and technology of fall detection. This paper gives a survey of fall detection for elderly and patient, focusing on identifying approaches and principles of the existing fall detection methods. To properly build the classification tree of the methods of fall detection we first study the characteristics of fall. Then according to what sensors and how sensors are used we first divide the methods of fall detection into three approaches: wearable device, ambience device, and camera-based. Further we divide each approach into two to three classes according to the used principles. For each class of algorithm we analyze their merits and demerits. We also give comments on how we can improve some algorithms.

Approaches and principles of fall detection for elderly and patient

This paper deals with an active gate drive (AGD) technology for high-power insulated gate bipolar transistors (IGBTs). It is based on an optimal combination of several requirements necessary for good switching performance under hard-switching conditions. The scheme specifically combines together the slow drive requirements for low noise and switching stress and the fast drive requirements for high-speed switching and low switching energy loss. The gate drive can also effectively dampen oscillations during low-current turn-on transient in the IGBT. This paper looks at the conflicting requirements of the conventional gate drive circuit design and demonstrates using experimental results that the proposed three-stage AGD technique can be an effective solution.

An input sensor for an electronic device (100) which includes a touch sensor panel (104), multiple electrodes and a sensor circuit. The electrodes include multiple regional electrodes and multiple local electrodes. Each regional electrode covers a corresponding region of the touch sensor panel and each local electrode includes multiple pads including one pad located within each of the regional electrodes. The electrodes are distributed so that a touch anywhere across the touch sensor panel is detected by at least one regional electrode and at least one local electrode. A sensor circuit determines a value for each of the electrodes indicating relative change, and compares relative values of the electrodes to identify a location of a touch of the touch sensor panel. The regional electrodes are used to determine a region of a touch and the local electrodes are used to determine a more specific touch location within the determined region.

A system and method is provided for detection of a human body fall event. The fall detection system (100, 200) includes a monitoring unit (102, 202), including a plurality of accelerometers (106, 206), a processor (108, 208) and a wireless transmitter (110, 210). The plurality of accelerometers (106, 206) provide acceleration measurements to the processor (108, 208), the measurements describing the current acceleration of the person wearing the monitoring unit (102, 202) in all directions. The processor (108, 208) receives the acceleration measurements and compares the acceleration measurements to a value range to determine if the wearer is currently experiencing a fall event. The processor (108, 208) generates a signal in response to the detection of a fall event and the transmitter (110, 210) transmits the signal to a remote signal receiver (104, 204). The system and method can further detect non-movement in the wearer of the monitoring unit (102, 202) subsequent to the fall event to detect an unconscious wearer.

A system and method is provided for electronic device fall detection. The system and method provides the ability to reliably detect falls even in the presence of other motion in the electronic device. The fall detection system includes a plurality of accelerometers and a processor. The plurality of accelerometers provides acceleration measurements to the processor, with these measurements describing the current acceleration of the electronic device in all directions. The processor receives the acceleration measurements and compares the acceleration measurements to a value range to determine if the device is currently falling. Furthermore, the system and method can reliably detect a non-linear fall, such as when the fall is accompanied with device rotation or initiated by additional external force. To detect a non-linear fall, the processor compares combinations of acceleration measurements to a value range and further determines the smoothness of the acceleration measurement combinations.

A system and method is provided for predicting an imbalance condition in a rotating device. The rotational imbalance prediction system (100) includes an accelerometer assembly (104), including at least one accelerometer (304), and a processor (306). The at least one accelerometer (304) provides acceleration measurements to the processor (306), the measurements describing the current acceleration of an orbit of the rotational device (102).

The processor (306) generates a signal in response to the prediction of an imbalance condition and transmits the signal to a motor control (308) or a remote alarm module (302). The system and method provides for countermeasures to be taken in response to the prediction of an imbalance condition, thereby eliminating the imbalance condition.

The processor ( 36 ) executes an auto-calibration process ( 46 ) that entails collecting ( 94 ) acceleration datasets ( 96 ) and identifying a subset ( 130 ) of acceleration datasets ( 132 ) in which each of the acceleration datasets ( 132 ) represents a scenario in which the accelerometer ( 22 ) is in a static position and in which the acceleration datasets ( 132 ) represent a variety of orientations of the accelerometer ( 22 ). The subset ( 130 ) of acceleration datasets ( 132 ) is utilized to compute updated calibration parameters ( 184 ). Current calibration parameters ( 48 ) are compared to the updated parameters ( 184 ) to determine validity of the current parameters ( 48 ). When the current parameters ( 48 ) are invalid, they are replaced with the updated parameters ( 184 ), and the updated parameters ( 184 ) are implemented to calibrate the accelerometer ( 22 ).
