Abstract: A twin-blade safety razor comprising a two compartment handle or bulb, one for storing air, the other for storing a liquid. Air and liquid are simultaneously dispensed from the separate compartments so as to form a fine spray for cleaning debris from between the blades of the razor assembly or for cleaning a part of the body to be shaved.

Abstract: A method for monitoring food intake for an individual and providing an indication when the food intake exceeds a predetermined allowable amount, comprising the steps of monitoring the individual over a predetermined period of time in order to establish an empirical relationship for the individual between a change in at least one physiological variable and a rate and/or amount of food intake. Upon starting each meal, the change in each of the relevant physiological variables is measured so as to determine from the empirical relationship an estimated rate and/or amount of food intake. This permits calculation of a maximum eating time to intake the predetermined allowable amount for the individual, upon expiry of which an indication is given to stop eating.
