Lost frame reconstruction is described. The main body is an elongated strap member having two lateral edges, two end edges, a top side and a bottom side. The various apparatus embodiments include a sensor adapted to provide a signal in response to at least one parameter of a plurality of parameters; and a frequency controller adapted to modify the resonant frequency in response to the second signal. The identified sip as well as sip characteristics and the liquid consumption metric may be displayed on the smart band, and also may be transmitted to a server for storage and for display on another network-enabled device.
