A multi-bus, energy storage system includes an energy storage bus that provides energy storage; a power demand bus that provides power delivery; and a supervisory system comprised of a system supervisor.

Multi-bus energy storage system

A power-line/communication system including: (a) a power-line/communication bus comprised of first and second conductors; (b) one or more capacitor-based, receiver/transmitter nodes, parallel-connected to the first and second conductors; (c) a shunt capacitor parallel-connected to the first and second conductors; and (d) a current transformer having a secondary winding connected in series to the first conductor, which secondary winding is disposed between the shunt capacitor at one end thereof and the receiver/transmitter nodes at the other end thereof.

Power-line/communication system

Method of operating a bidirectional DC DC converter that transfers power among an energy source (for example, a solar PV array), an energy storage system, and an energy usage system (for example, a DC AC inverter) to control the charge and discharge times of the energy storage system so that power harvested during peak energy source production can be stored and can later be released to the energy usage system at predetermined times.

Method of operating a bidirectional DC DC converter

A bidirectional DC DC converter that transfers power among an energy source (for example, a solar PV array), an energy storage system, and an energy usage system (for example, a DC AC inverter). The converter controls the charge and discharge times of the energy storage system so that power harvested during daylight can be metered to the DC AC inverter at predetermined times. During charge times, the converter utilizes synchronous rectification when down-converting higher voltages to lower voltages and during discharge times the converter utilizes variable overlapping of switch drive signals to provide a continuous range of voltage levels of transferred power from the energy storage system to the DC AC inverter.

A DC AC inverter system includes a full bridge DC AC inverter, a first module with a first capacitance connected to a positive DC input and an intermediate output, and a second module with a second capacitance connected to a negative DC input and to the intermediate output, wherein the first and second capacitance is greater than P&#x394;A/(V&#x394;*Vnom*2&#x3c0;f); (a) P&#x394; is a predetermined power imbalance between a first output and the intermediate output and a second output and the intermediate output; (b) Vnom is a predetermined nominal output voltage between the first output and the intermediate output (V1) and the second output and the intermediate output (V2); (c) V&#x394; is a predetermined fraction of voltage difference, relative to Vnom, between V1 and V2 when there is a power imbalance P&#x394;; and (d) f is a frequency of V1 or V2.

The present invention provides an adjustable, universal screed guide/control joint clip for positioning screed guide/control joints utilized in the placement of concrete in concrete slabs. The adjustable universal screed guide clip allows for the exact adjustment of the height of the screed guide attached thereto for the placement of the concrete slabs, and the adjustable universal screed guide clip also allows for the installation of the screed guide in applications which heretofore were not possible. The adjustable, universal screed guide/control joint clip of the present invention is capable of accommodating both large and small profile screed guides.

A first housing has an open end and a sidewall with at least one slot. A second housing has an open first end in operative association with the open end of the first housing. The second housing has an open second end. A fan assembly is secured between the first and second housings to effect a flow of air through the slot and open second end of the second housing. A mesh fabric entraps insects entrained against the fabric by the flow of air through the fabric. A source of light within the first housing attracts flying insects toward the slot and into the first housing. Once in the first housing the flow of air from the fan will entrain the flying insects in a path of movement from the first housing to the second housing and then to the fabric.

Building structure

The present invention relates to a system of building construction as well as the specific components of the building itself wherein a plurality of continuously configured truss-like primary framers are arranged in spaced apart parallel relation to one another and wherein each comprises a roof section, a floor section and oppositely disposed wall sections. The corresponding sections of each primary framer collectively define the roof, floor and wall portions of the resulting building and further wherein secondary framers of somewhat similar structural configuration form the end portions of the building. A characterizing feature of the resulting building is at least one longitudinal side wall having outward extending angularly oriented first and second wall portions which deviate from the conventional vertically oriented external bearing walls found in conventional building construction.
