Abstract: A steam distribution control system and method for a steam heating system are provided. The steam heating system may include a plurality of radiators, a boiler that provides steam to the plurality of radiators, and a plurality of steam pipes that carry the steam to the plurality of radiators, respectively. The steam distribution control system may include a plurality of steam-air vents provided at the plurality of radiators, respectively, and a central controller in communication with the plurality of steam-air vents that selectively controls the plurality of steam-air vents to control an amount of steam distributed into each of the plurality of radiators. The method may include providing a steam-air vent at each of the plurality of radiators, and selectively controlling the plurality of steam-air vents to control an amount of steam distributed into each of the plurality of radiators.

Abstract: A controller for a musical effects unit enables control of an effects unit through the use of two touch buttons mounted on a guitar, or other instrument. The two touch switches form an input to a microprocessor utilizing control software to interpret the sequential contacting of the buttons. The software converts the sequential manipulation of the buttons into a selection criteria which is then transmitted to the effects unit to effect the selection of a pre-programmed or pre-selected effect. The timing of the sequencing of the two touch, or momentary switches may be adjusted in the software to suit the needs of the individual preforming artist.
