Patent number: 11927866Abstract: Onboard EC window controllers are described. The controllers are configured in close proximity to the EC window, for example, within the IGU. The controller may be part of a window assembly, which includes an IGU having one or more EC panes, and thus does not have to be matched with the EC window, and installed, in the field. The window controllers described herein have a number of advantages because they are matched to the IGU containing one or more EC devices and their proximity to the EC panes of the window overcomes a number of problems associated with conventional controller configurations. Also described are self-meshing networks for electrochromic windows.Type: GrantFiled: December 18, 2020Date of Patent: March 12, 2024Assignee: View, Inc.Inventors: Stephen C. Brown, Dhairya Shrivastava, Erich R. Klawuhn, Trevor Frank, Douglas Silkwood

Publication number: 20220297591Abstract: A flatbed rolling tarp system is a tarp covered structure that retracts and rolls from front to rear and rear to front or a track that is installed on a flatbed trailer. It's only purpose is to cover cargo. My innovation is to integrate pulleys and related components with main bow(s) enabling driver/operator (using ropes from the ground) to pull tie-downs from one side of system, up and over pulleys then release them on opposite side of system. Pulleys will be swivelable, removable, relocatable, and lockable.Type: ApplicationFiled: April 1, 2022Publication date: September 22, 2022Inventor: Douglas R. Brown

Publication number: 20190261579Abstract: A frost shield device may include a base having blocks. At least some of the blocks each may define a first through passageway and a second through passageway. The frost shield device may have poles, each pole having a first end to be received by one of the first through passageway and the second through passageway, and a second end. The frost shield device may also include a top ring coupled to the second ends of the poles, and a cover layer configured to extend from the base to the top ring, thereby covering a plant within the base.Type: ApplicationFiled: February 8, 2019Publication date: August 29, 2019Inventor: DOUGLAS R.

Patent number: 9693397Abstract: Apparatus is provided for inductively heat treating a circular surface of annular workpieces where at least one inductor pair is used to perform a scan induction heat treatment of the circular surface. Controlled movement of the inductors and application of quenchant is provided particularly at the initial and final heat treatment locations on the circular surface to enhance metallurgical uniformity of the annular workpiece at these locations. In combination with controlled movement of the inductors, a simultaneous power-frequency control scheme can be applied to the inductors during the heat treatment process with the apparatus.Type: GrantFiled: July 13, 2015Date of Patent: June 27, 2017Assignee: INDUCTOHEAT, INC.Inventors: Gary A. Doyon, Frank Andrä, Douglas R. Brown, Don L. Loveless, Valery I. Rudnev

Patent number: 8247749Abstract: Large, non-unitarily forged shaft workpieces such as a crankshaft have successive shaft features inductively heated and forged without cool down between each sectional forging process. The temperature profile along the axial length of the next section of the shaft workpiece to be inductively heated and forged is measured prior to heating, and the induced heat energy along the axial length of the next section is dynamically adjusted responsive to the measured temperature profile to achieve a required pre-forge temperature distribution along the axial length of the next section prior to forging.Type: GrantFiled: July 3, 2010Date of Patent: August 21, 2012Assignee: Inductoheat, Inc.Inventors: Gary A. Doyon, Douglas R. Brown, Don L. Loveless, Valery I. Rudnev

Patent number: 8222576Abstract: Apparatus and method are provided for induction heating of one or more components of a complex-shaped workpiece. The component is positioned within an opening formed by opposing pairs of arcuate coil structures formed in opposing inductor segments. One inductor segment is formed from electrically isolated inner and outer active inductor segments connected to one or more power supplies, while the other inductor segment is formed from electrically isolated inner and outer passive inductor segments that are magnetically coupled with respective inner and outer active inductor segments. Changing the output electrical parameters of the one or more power supplies controls the induction hardening along the transverse width of the workpiece with optional flux concentrators between opposing pairs of arcuate coil structures.Type: GrantFiled: January 16, 2010Date of Patent: July 17, 2012Assignee: Inductoheat, Inc.Inventors: Gary A. Doyon, Don L. Loveless, Douglas R. Brown, Valery I. Rudnev, Timothy G. Boussie, Glenville Colin Desmier

Patent number: 4381232Abstract: An improved electrodialysis stack electrode reversal system and method of operation is disclosed in which each of the electrode pairs forming an electrical stage in such stack are reversed on a sequential stage by stage basis. The sequential reversal is timed to occur in each of the series connected stages as the desired dilute product stream clears the stage substantially decreasing the amount of loss of partially treated product.Type: GrantFiled: August 24, 1981Date of Patent: April 26, 1983Assignee: Ionics, IncorporatedInventor: Douglas R.
