Abstract: A device has a housing with a top part that accommodates one or more pressable keys forming the user-interface of the device. Each specific key has a specific keycap. The top part is formed from a harder plastic element and a softer rubber layer in a two-shot injection molding process. The harder plastic element has one or more openings occupied by the softer rubber layer. The harder plastic element has a specific pin positioned in a specific hole of the softer rubber layer. The specific keycap has a bottom face with a specific protruding sleeve configured for engaging with the specific pin. The bottom face of the specific key and an area at a top face of the softer rubber layer have complimentarily shaped profiles configured for accurately orienting the keycap relative to the top part.

Abstract: A remote control extension system for controlling appliances (60,70,80). A remote control (20) is connected by means of a network (30) to an extender device (40). The remote control (20) transmits messages (110,120) to the extender (40) during the period, that a command (14) is to be transmitted from the extender to an appliance. The command is for example a command having a variable duration, such as Volume UP. The extender (40) receives the messages. It transmits the command as long as it receives the messages from the remote control. It finishes the transmission of the command, if an expected message has not been received at a predetermined time. In this way, the duration of a command is limited in case of network disturbances.

Abstract: A method of programming a Universal Remote Control is described. A user is requested to execute a command sequence comprising more than one command from an original Remote Control for controlling a device (306). The commands from said sequence are captured and analyzed (308). The analyzed commands are matched with a code-set or branches of a code-tree data base (310). The command sequence is used for generating a macro for executing an activity including the device (316).
