Patent number: 10989977Abstract: 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.Type: GrantFiled: July 10, 2019Date of Patent: April 27, 2021Assignee: View, Inc.Inventors: Dhairya Shrivastava, Anshu A. Pradhan, Stephen Clark Brown, David Walter Groechel, Robert T. Rozbicki

Patent number: 10988094Abstract: A trim component, such as a grill of a vehicle, includes a substrate having a 3-dimensional shape and defining a disrupted reflective surface including a plurality of facets over a curved surface. Each of the facets is configured to reflect an incident light beam in a common direction, for example, toward a given target. A reflective coating, such as a chrome plating layer, overlies the disrupted reflective surface. The facets may have similar shapes and/or be arranged in a repeating pattern, but with one or more irregular features. The sizes, shapes, and/or orientation direction of the facets may varying in a gradient based on the curvature of the curved surface. The trim component also includes a light source to illuminate the disrupted reflective surface. The light source may be hidden so it is not directly visible to a viewer, but instead is reflected by the disrupted reflective surface.Type: GrantFiled: June 25, 2019Date of Patent: April 27, 2021Assignee: LACKS ENTERPRISES, INC.Inventors: David Walters, Thomas Hawkins

Publication number: 20210120210Abstract: A secure teleconference with a patient treatment room may be initiated by receiving, at a central facility, a request for a conference from a clinician application, and then identifying a virtual meeting room and sending an identifier for a conference to the treatment room. The conference is then be established by receiving a call at the central facility from the treatment room, where the call identifies the conference. The central facility then joins the treatment room and the clinician application to the virtual meeting room. Teleconferences may thus be established without reference to sensitive patient information. For security, no incoming conferencing calls may be made to the treatment room directly, and virtual meeting rooms may be eliminated after single use. A call may further be initiated by receiving a request from the treatment room, e.g., which is processed by the central facility to alert one or more clinicians.Type: ApplicationFiled: October 16, 2020Publication date: April 22, 2021Inventors: John Mitchell Vitale, David Walter Galas, Jennifer R.

Publication number: 20200370688Abstract: A method is provided for forming a gasket for sealing opposing flange surfaces of a pipe having corrosive fluid flowing therethrough. The method comprises defining a gasket profile incorporating a serrated profile core having a flange extending radially inward therefrom. A deformable pillow extends radially inward from the serrated profile core, to define a gasket intermediate portion about the flange, and a gasket inner portion radially inward from the flange. The deformable pillow material and thickness are selected such that upon compression to a thickness no less than the core thickness, the gasket inner portion exhibits a stress level sufficient to preclude corrosive liquid flowing through the pipe from passing radially outward beyond the gasket inner portion, and the gasket intermediate portion exhibits a stress level sufficient to preclude gas and liquid flowing through the pipe from passing radially outward beyond the gasket intermediate portion.Type: ApplicationFiled: August 14, 2020Publication date: November 26, 2020Applicant: Eriks N.V.Inventors: Alan Stubblefield, David Walter Reeves

Patent number: 10807090Abstract: An apparatus configured for displacing fluid from a fluid container comprises first and second actuators configured to be movable together until the first actuator compresses a first part of the fluid container and then moveable independently until the second actuator compresses a second part of the fluid container. Fluid containers comprise a first vessel, a second vessel, and a sealing partition preventing fluid flow from the second vessel and further include a piercing point for piercing the sealing partition to permit fluid flow from the second vessel. A fluid container comprises a vessel configured to be collapsed to displace fluid from the vessel, a housing surrounding at least a portion of the vessel, and a floating compression plate movably disposed within the housing and configured to permit an external actuator to press the compression plate into the vessel to collapse the vessel and displace the fluid contents therefrom.Type: GrantFiled: August 3, 2016Date of Patent: October 20, 2020Assignee: GenMark Diagnostics, Inc.Inventors: David Walter Wright, Dominic Aiello
