Abstract: Processes and apparatus for indicating a shower stage are disclosed. The apparatus includes a housing having an inlet and an outlet with a shower water passage extending between them. The inlet communicates with a water supply and the outlet communicates with shower head apertures. A light indicator system in the housing is automatically operable in a first condition during a first stage of the session and a second condition during a second stage, the lighting conditions being visible to the person who is showering. The stages may be determined by the passage of time or by the passage of shower water volume through the device. Seeing the first and second conditions prompts the person who is showering to use less shower water.

Abstract: A portable communication device is disclosed comprising a front face (3) having a plurality of openings therein, and an array (6) of keys. Each key has a switch actuator, a switching element, and coupling means. The switch actuator has an upper surface bounded by side walls, and the switch actuator of each key of the array (6) protrudes from one of the plurality of openings to provide its upper surface for tactile actuation by a user and is physically discrete from the others. The coupling means couples the tactile actuation of the upper surface by a user to the switching element.
