Abstract: A music device for making music includes a first input part for generating a first signal based on a user input, a music signal generator for generating a music signal based on the first signal, a second input part for generating a second signal based on a user input, the second signal controlling the music signal generator, and the second input part including a plurality of first buttons which correspond to a range including at least one of a key, a note and a chord, and a plurality of second buttons which correspond to at least one of a note and a musical scale within the range.

Abstract: A monitoring device for a distributed system includes a signal receiver for receiving a service signal for a service provided by a service provider to a receiving location, and an operating condition indicator which indicates to the service provider an operating condition of the service at the receiving location based on the received service signal.

Abstract: A system includes a fuel source for providing a fuel, a first expansion valve formed in a first fuel line connected to the fuel source, for expanding the fuel, and a heat transfer device for delivering a heat transfer medium to the first expansion valve such that the heat transfer medium is cooled by contacting the first expansion valve. Another system includes a fuel source for providing a fuel, a first expansion valve formed in a first fuel line connected to the fuel source, for expanding the fuel, a heat exchanger connected via the first fuel line to the expansion valve, the heat exchanger being cooled by the expanded fuel, and a fan for blowing air over the heat exchanger such that the air is cooled by contacting the heat exchanger. Another system includes pneumatic or hydraulic operated system devices.
