  • Publication number: 20130141007
    Abstract: A modular system and method for providing power for LED lighting systems. The power source unit comprises (1) a power supply that converts A/C voltage to regulated D/C voltage, (2) a configurable intelligent gateway module that receives the regulated D/C voltage and places it on a power bus to which one or more power node modules and any accessories in need of power, such as motion detectors or cooling units, are coupled, and (3) an intelligent power node module that converts the regulated D/C voltage to a regulated D/C current and provides it to the particular LED Light Module (LLM), and which also receives data from the LLM, such as temperature data, and adjusts the regulated current accordingly. The gateway module also may receive control data from control devices, such as dimmers or wireless controllers, and instruct the power node module to regulate its output current accordingly.

  • Patent number: 7578734
    Abstract: An HVAC unit ventilator, particularly suited for schools and hotels, includes a single damper blade driven directly by a motor to control a supply air's mixture of return air and outside air. The damper blade is selectively pivotal to a full outside air position, a full return air position, and various intermediate mixed-air positions. The damper blade has flexible edge and end seals that create little if any frictional drag as the damper blade pivots to the intermediate positions, yet the seals provide a positive, tight seal when the damper stops at either the full outside air position or the full return air position. The unit ventilator includes a filter frame that not only supports an air filter but also provides the damper blade with sealing surfaces and structural support. For rigidity, the damper blade has somewhat of a box-like structure that is bi-directionally reinforced by ribs and triangular gussets.
