Patent number: 10827584Abstract: A system for controlling a load including a plurality of LEDs includes a timing circuit, an encoder and a configuration switching circuit. The timing circuit generates time-off switching points and time-on switching points. The encoder generates a load voltage by modifying a rectified line voltage using the time-off switching points and the time-on switching points. The configuration switching circuit determines a maximum voltage of a line voltage input to the driver system, selects a configuration for the plurality of LEDs based on the maximum voltage, communicates the configuration for the plurality of LEDs to the load, dynamically reconfigures the configuration for the plurality of LEDs based on the modified rectified line voltage, the dynamically reconfiguration of the configuration including changing at least one of the first quantity of LEDs in electrically coupled in series and the second quantity of LEDs electrically coupled in parallel.Type: GrantFiled: April 26, 2019Date of Patent: November 3, 2020Assignee: LiteIdeas, LLCInventors: Todd Hodrinsky, James Epperson, Calvin McCoy Winey, III, Karl Kenneth Karash, Michael Varanka

Patent number: 9114571Abstract: An apparatus and method of fabricating a three-dimensional model which reduces occurrence of one a hairline crack(s), stress fracture(s), break(s), flaw(s) and/or other imperfection(s) in the final three-dimensional model. The method comprising the steps of selecting the model material, selecting the sacrificial material, and adding at least one additive to the sacrificial material for at least one of increasing the thermal conductivity, decreasing a coefficient of thermal expansion or decreasing an ability of the sacrificial material to transmit stress to the model material. The three-dimensional composite model is built by depositing a plurality of layers one on top of another.Type: GrantFiled: October 26, 2012Date of Patent: August 25, 2015Assignee: Solidscape, Inc.Inventors: Xiaorong You, Jennifer Elizabeth Gingras, Calvin McCoy Winey, John T.

Publication number: 20110285052Abstract: An apparatus and method for fabricating a three dimensional model from a composite model formed or a plurality of successive layers of model material and sacrificial mold material. Each successive layer is constructed by depositing, drop-by-drop, at least one line of sacrifical mold material delineating at least one boundary of the model material within the layer and thereafter depositing the model material onto all delineated regions of the layer by spray deposition. Each successive layer is completed by a planing process which removes the undesired thickness of both the sacrificial and the model materials. Following completion of the composite model, the sacrificial mold material is removable from the composite model, by a process effecting only the sacrificial mold material, to produce the three dimensional model. A device, for depositing the model material at the rate faster than the rate that the mold material is deposited, is also described.Type: ApplicationFiled: August 8, 2011Publication date: November 24, 2011Applicant: SOLIDSCAPE, INC.Inventors: John Theodore WIGAND, Calvin McCoy WINEY, III, Michael VARANKA

Publication number: 20100021638Abstract: A method for fabricating a three dimensional model by fabricating a composite model formed of a plurality of successive layers comprised of one or more materials wherein each successive layer is formed by depositing at least first material delineating boundaries of at least one first area of the layer by a drop-by-drop deposition and depositing at least a second material over the layer by a rapid deposition method, and may include the deposition of a third material by a drop-by-drop or rapid deposition method and will include planing the layer to a uniform thickness and selectively removing the first and second materials, and third material if present, by successive removal methods, each of which effects only one of the materials.Type: ApplicationFiled: July 27, 2009Publication date: January 28, 2010Applicant: SOLIDSCAPE, INC.Inventors: Michael VARANKA, John Theodore WIGAND, Calvin McCoy WINEY
