Patent number: 11669980Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for generating motion detection based on optical flow. One of the methods includes obtaining a first image of a scene in an environment taken by an agent at a first time point and a second image of the scene at a second later time point. A point cloud characterizing the scene in the environment is obtained. A predicted optical flow is determined between the first image and the second image. A respective initial flow prediction for the point that represents motion of the point between the two time points is determined. A respective ego motion flow estimate for the point that represents a motion of the point induced by ego motion of the agent is determined. A respective motion prediction that indicates whether the point was static or in motion between the two time points is determined.Type: GrantFiled: July 23, 2021Date of Patent: June 6, 2023Assignee: Waymo LLCInventors: Daniel Rudolf Maurer, Alper Ayvaci, Nichola Abdo, Christopher John Sweeney, Robert William Anderson

Publication number: 20230035454Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for generating an optical flow label from a lidar point cloud. One of the methods includes obtaining data specifying a training example, including a first image of a scene in an environment captured at a first time point and a second image of the scene in the environment captured at a second time point. For each of a plurality of lidar points, a respective second corresponding pixel in the second image is obtained and a respective velocity estimate for the lidar point at the second time point is obtained. A respective first corresponding pixel in the first image is determined using the velocity estimate for the lidar point. A proxy optical flow ground truth for the training example is generated based on an estimate of optical flow of the pixel between the first and second images.Type: ApplicationFiled: July 23, 2021Publication date: February 2, 2023Inventors: Daniel Rudolf Maurer, Alper Ayvaci, Robert William Anderson, Rico Jonschkowski, Austin Charles Stone, Anelia Angelova, Nichola Abdo, Christopher John Sweeney

Patent number: 8656946Abstract: A double check valve (10) with two separate elements (20, 25) individually movable to close the valve and collectively movable to open the valve. The separate elements are independently closing the valve, and collectively controllable to open the valve, to allow pressure release or to allow injection of fluid (e.g. lubricant). In an example, the double check valve includes two separate check valves with a stinger element (30) between them which is operable to internally sting the one check valve when (e.g. by action of) the other check valve is stung by a user (e.g. using a stinger means) thereby to open both check valves individually and the double check valve as a whole.Type: GrantFiled: May 22, 2008Date of Patent: February 25, 2014Assignee: Anson LimitedInventors: Robert William Anderson, Neil Colin Kennedy

Patent number: 7153575Abstract: The present invention relates to coated particulate matter wherein the particles are individually coated with a first set of one or more layers of a curable resin, for example, a combination of phenolic/furan resin or furan resin or phenolic-furan-formaldehyde terpolymer, on a proppant such as sand, and the first set of layers is coated with a second set of one or more layers of a curable resin, for example, a novolac resin with curative. Methods for making and using this coated product as a proppant, gravel pack and for sand control are also disclosed.Type: GrantFiled: May 28, 2003Date of Patent: December 26, 2006Assignee: Borden Chemical, Inc.Inventors: Robert William Anderson, Tom Diep, Avis Lloyd McCrary

Publication number: 20030116742Abstract: A gate valve comprises a body member having a bore therethrough, a gate member movable transversely of the bore between an open position permitting full flow through the bore, and a closed position preventing flow through the bore, and a stem portion mounted in the body member to be axially fixed therein but rotatable relative thereto, one end of the stem portion co-operating with the gate member whereby rotation of the stem portion results in movement of the gate member between its open and closed positions, a sleeve member secured to, to be rotatable with, the stem portion external of the body member and defining an annular gap between the stem portion and the sleeve member, and an annular skirt within said gap, the skirt being rotatably fixed but axially movable relative to the stem portion, the skirt and sleeve member threadedly engaging one another such that rotation of the sleeve member results in axial movement of the skirt relative to the sleeve member and the stem portion in a direction dependent upoType: ApplicationFiled: June 10, 2002Publication date: June 26, 2003Inventors: Robert William Anderson, David Michael Kay

Patent number: 4017680Abstract: Improvements and modifications are described to an image analyzing system in which an image of a field under analysis is displayed on a television monitor screen and features can be edited by adding or subtracting feature content to or from the display (and corresponding signal content to or from the signal which is to be processed for analysis) using a light pen.One improvement provides for straight line interpolation between points in the display selected by the light pen during successive frame scans, so that a continuous trace and therefore corresponding signal is produced in the display corresponding to the path traced out by the light pen.Another provides for an alarm signal to be generated if the storage facility used for storing the locus of the trace to allow its reconstruction during successive frame scans, becomes more than a given percentage occupied.Type: GrantFiled: July 8, 1975Date of Patent: April 12, 1977Assignee: Image Analysing Computers LimitedInventors: Robert William Anderson, William Ralph Knowles, John Edward Culley
