A method and system of managing ringtones and alarms by intercepting device events, associating them with user events, smartphone sensor data and text search to intelligently alter the smartphone ringtones without user intervention. The mechanism is movable between a first configuration in which the first member closes a recess in the console top, and a second configuration in which the first member extends away from the console top and the second member is arranged such that it can support a load while the mechanism is retained in the second configuration. The outputs from the channels are input to a differencing circuit to obtain absolute difference values. The device may further comprise an assay reagent component for detecting an analayte of the oral fluid specimen. The grip housing includes a heating element that is operable to provide a heat output, and a heater control dial is coupled to the second end of the handgrip to control the heat output of the heating element.
