    Abstract: Acoustic Voice Activity Detection (AVAD) methods and systems are described. The AVAD methods and systems, including corresponding algorithms or programs, use microphones to generate virtual directional microphones which have very similar noise responses and very dissimilar speech responses. The ratio of the energies of the virtual microphones is then calculated over a given window size and the ratio can then be used with a variety of methods to generate a VAD signal. The virtual microphones can be constructed using either an adaptive or a fixed filter.

    Abstract: Embodiments of the present application relate generally to electrical and electronic hardware, computer software, wired and wireless network communications, wearable, hand held, portable computing devices for facilitating communication of information, and the fields of healthcare and personal health. More specifically the present application relates to a new and useful systems, methods and apparatus for estimating body fat in a user with applications in the healthcare and personal health fields. An electronic device, such as a portable electronic device (e.g., smartphone, pad, tablet, etc.) may include software (e.g., an APP) to implement body fat estimates of a user and may use hardware and/or software resident in the electronic device (e.g., display, accelerometer, gyroscopes, transducers, vibration engines, speakers, microphones, GPS capability, etc.) to aid a user in placing the electronic device at instructed location on the user's body and to apply an impulse to the body at instructed locations.
