Abstract: A system for dispensing a desired beverage, the system comprising: a housing; a dispensing unit disposed in the housing for dispensing the selected beverage; a first user interface for sighted users, the first user interface being secured to the housing and comprising a screen; a second user interface for visually impaired users, the second user interface being secured to the housing and comprising a plurality of buttons each associated with a respective command; and a control unit disposed within the housing and operatively connected to the dispensing unit and the first and second user interfaces, the control unit for operating the system in a first mode of operation in which commands are to be inputted via the first user interface and a second mode of operation in which the command are to be inputted via the second user interface.

Abstract: An attachment system for connecting a piston cover to a piston body of a french press coffee maker comprises a plate having a top surface and a bottom surface. The bottom surface of the plate is adapted to be in contact with a top surface of the piston cover. The bottom surface has at least one peg extending therefrom. The at least one peg is adapted to be inserted into at least one aperture of the piston cover and corresponding at least one aperture of the piston body. The at least one peg is adapted to be secured to the bottom surface of the piston body. Piston heads for a brewing chamber of a french press coffee maker are also presented.

Abstract: A circuit and a method for compensating the floating differential capacitance appearing between two recording microelectrodes is presented. It is shown how this floating capacitance can be neutralized so that current in any microelectrode can be injected without any significant cross-talk picked up by the other. It is a fully symmetrical compensation.
