Abstract: A building power management controller comprises a plurality of modules connected by a two-wire network. Each module comprises a data transceiver device, controlled by a microprocessor to both transmit data to the other modules and to a central unit via the two-wire network, and to receive information via this two-wire network. The modules are supplied with power by the two-wire network. When two modules transmit simultaneously, one takes priority so as not to disturb the messages transmitted.

Abstract: The invention concerns a kinematic system of an industrial robot and a sequential control system of its operating cycle.The robot comprises a vertical spindle supporting a main rotating arm and a forearm fixed to a gripping component. A first vertical transfer jack is provided at the end of the forearm. Arms are mounted via bearings on a loose spindle in a link and can swivel, driven by servo-motors in a horizontal plane so as to form a kinematic system functioning in cylindrical coordinates. The servo-motors are programmed to drive the gripping component through a linear trajectory at the beginning of the cycle. A releasable couping system with memory device is provided for the tool-holder. The controller control system is arranged to ensure the transitory readjustment of each arm to a starting position.
