Abstract: The invention provides a beverage preparation vessel comprising: a base for supporting the vessel on a surface, a wall extending from the base and projecting upwardly therefrom to form a receptacle for receiving liquid, and a rim extending around an upper edge of the wall defining an opening to the receptacle and having a spout for pouring the liquid from the vessel, wherein the wall has a closed double-walled configuration comprising an inner wall and an outer wall being disposed in a spaced apart arrangement such that a gap is formed therebetween wherein the outer wall is thermally insulated from the inner wall and defines an external surface that can be gripped by a hand of a user, and the inner wall defines an internal surface that contacts the liquid in the receptacle and has measurement markings to enable the user to visibly measure the volume of liquid in the receptacle, and wherein the vessel has a profile that allows alike vessels to be stacked in a nested arrangement.

Abstract: The invention relates to a method for determining a touch event provided by a user on an interaction surface of a touch sensitive device comprising the steps of: sensing a raw signal by a transducer, in particular by a piezoelectric transducer and low-pass filtering the sensed signal, segmenting the filtered raw signal into a baseline signal and at least one useful signal, and analyzing the at least one useful signal to determine properties of the touch event.
