There is provided a method and apparatus for detecting a fall event of the user. The method includes collecting data associated with activities of the user from sensors and distributing the collected data to data sub-windows using signal windowing and segmentation, the data sub-windows indicative of a pre-fall moment, a fall moment, and a post-fall moment. The method includes extracting features from the data sub-windows and determining whether the event is a fall event using the extracted features. The determination of whether the event is a fall event can be determined by applied support vector machine technique. The developed machine learning based methods may balance a trade-off between accuracy and complexity of the evaluation. The method further includes multiple rejection filters mitigate false alarms due to fall-like activities of daily living. The method includes a personalization process to update the machine learning based methods associated with each user.

Method and apparatus for detecting fall events

A diffuse-optical-spectroscopy system and method for scanning human tissue. The system includes: (a) a handheld probe operable to emit electromagnetic radiation at one or more wavelengths corresponding to absorption associated with one or more human-tissue constituents, respectively, the handheld probe being operable to detect received electromagnetic radiation at each of the wavelengths; and (b) a processor operable to produce, in response to the received electromagnetic radiation, one or more cross-sectional images of the human tissue respectively associated with the wavelengths. The handheld probe includes first and second sources for emitting the electromagnetic radiation and one or more sensors for detecting the received electromagnetic radiation. The sensors are aligned along a first axis and face in an outward direction. The first and second sources are aligned along the first axis, face in the outward direction, and are disposed on either side of the sensors.
