Abstract: A system monitor sensors which control actuating elements in a building. The supervision unit essentially collects information from the sensors and controls the actuating elements. A precable system in the building connects the supervision unit to input/output connections of a plurality of interconnection devices. The plurality of interconnection devices each include a plurality of terminal boards connected to the sensors and actuating elements through a first set of cables. A microprocessor has a portion of the I/O connections connected to the terminal board through a second set of cables, transmitting signals between the actuating elements, sensors and the supervision unit.

Abstract: The invention is directed to a golf club of the iron type having an improved mass distribution. More particularly, the rear portion of the club head has a main cavity extending towards the striking face and a peripheral mass belt extending around the main cavity defining heel, toe, upper and lower perimeter portions. The upper perimeter portion of the peripheral mass belt includes an elongated recess which is progressively connected to the upper edge portion of the club head along an undercut, the undercut having a height that generally increases in a direction toward the toe and a thickness with respect to the striking face that increases progressively in a direction toward the upper edge portion.

Abstract: The invention is directed to a golf club of the iron type having an improved mass distribution. More particularly, the rear portion of the club head has a main cavity extending towards the striking face and a peripheral mass belt extending around the main cavity defining heel, toe, upper and lower perimeter portions. The upper perimeter portion of the peripheral mass belt includes a secondary recess which has a volume smaller than the volume of the main cavity and a volume per unit length that increases in a direction toward the toe of the club head.
