Abstract: In one aspect the invention provides a shot glass assembly comprising a cup suitable to hold a quantity of liquid, at least one load sensor, a microcomputer and a power source. The load sensor is operative to sense the weight of the cup and any liquid therein and provides a first signal. The microcomputer may process the first signal to provide a first output that is indicative of an amount of liquid held in the cup. The shot glass assembly may further comprise an accelerometer to provide a second signal that is indicative of any motion that may be experienced by the cup. The microcomputer may be programmed to process the first signal, and any second signal, to generate a second output that is indicative of a total volume of liquid held with the cup over a period of time.
