International Classification:

F24J 2/10
F24J 2/38
F24J 2/52

US Classification:

126600, 126696, 126697, 126685

Abstract:

Solar energy may be harvested utilizing arrays of solar collectors, supported and articulated to follow movement of the sun. Particular systems include arrays of solar collectors mounted on an elevation-azimuth tracking structure. From the ground up, embodiments of this system may include a Ground Interface, a Base, an Upper Truss, and a Collector. The system is designed to transmit loads with minimal deflection from the surface of the collector to the ground, while tracking the position of the sun across the sky. The use of structural, actuator, and collector elements with a minimum amount of low-cost materials, and which are able to be mass produced, allows large scale deployment of the system at reduced cost.

US Classification:

136246, 264 27, 264 19, 156145, 359853

Abstract:

Embodiments of the present invention include structures and methods for enhancing illumination uniformity from solar concentrators. Certain embodiments may use features on a reflective layer to globally correct for deviation in reflective behavior from a desired shape. Local features such as facets on a reflective layer are formed such that the resulting illumination profile represents a superposition of multiple facets. Features may be formed on a back film to correct the reflectance of the back film. In some embodiments, features may be formed on a front film to correct a profile from refraction. In some embodiments the corrections are for line concentrators. Global and local correction techniques may be used together, and may be used on front film or reflective film(s) together or separately. Global and/or local correction may also be used in combination with other approaches, such as secondary optic receiver compensation.

International Classification:

H01L 31/052
H01L 31/05
H01L 31/042

US Classification:

136246, 136251

Abstract:

Embodiments of the present invention may utilize one or more techniques, alone or in combination, to maximize a surface area of a receiver that is configured to convert light into another form of energy. One technique enhances collection efficiency by controlling a size, shape, and/or position of a cell relative to an expected illumination profile under various conditions. Another technique positions non-active elements (such as electrical contacts and/or interconnects) on surfaces likely to be shaded from incident light by other elements of the receiver. Another technique utilizes embodiments of interconnect structures occupying a small footprint. According to certain embodiments, the receiver may be cooled by exposure to a fluid such as water or air.

International Classification:

B22F 3/105

Abstract:

A system for fabricating an object includes an extruder for one or more deposition materials. The extruder has at least one nozzle with a nozzle tip that includes an exit orifice and has a width that is equal to or larger than a width of the exit orifice. The system also includes a controller coupled with the extruder, the controller configured to apply a correction factor that has been calculated for a path of the nozzle based on a slope of a surface of an object to be fabricated. The correction factor for a positive slope is different from that for a negative slope. The extruder is configured to cause movement of the nozzle along the path to deposit material on the slope of the surface of the object, and the correction factor removes differences in thickness of the deposited material caused by the slope in relation to the path.

Abstract:

A method includes independently controlling a feed rate for each of at least two different input materials for three dimensional (3D) printing to generate a processed material that varies continuously in composition along at least a portion of its length, adding syncing features to the processed material at specific locations of the processed material, and creating data that coordinates the specific locations of the processed material with the continuous variation in composition of the processed material, wherein the data and the syncing features are useable by a 3D printer to synchronize the continuous variation in composition of the processed material with volumetric or surface locations of an object during 3D printing of the object using the processed material.

Abstract:

A fused filament fabrication three dimensional printing system includes a build platform, an extruder for one or more deposition materials, the extruder including at least one nozzle movable relative to the build platform, and a controller configured to control the relative movement between the build platform and the nozzle, and to cause material to be extruded out of the nozzle to form a 3D object on the build platform. The build platform includes a first plate on which the 3D object is formed, a second plate that is positioned vertically below the first plate and defines at least one gap between the first and second plates, and a heating element that is configured to heat the second plate. The first plate defines at least one opening that is configured to allow passage of material extruded from the nozzle into the at least one gap between the first and second plates.
