Publication number: 20220244352Abstract: A method, apparatus, and system for detecting presence of an object of low radar cross section RCS (250) in an environment (200) are provided. Radar detection at one or more radar frequencies greater than 2 GHz is used to determine a steady state response profile (300) of the environment (200). The steady state response profile (300) comprises at least one indication of one or more reflected signals (202) from an object of high RCS in the environment (200). Radar detection at the one or more radar frequencies is then used to determine a test response profile (600) of the environment (200). The test response profile (600) is compared with the steady state response profile (300) to determine a presence of a, object of low RCS (250) in the environment by identifying at least partial absence of at least one of the reflected signals (202) in the test response profile (600).Type: ApplicationFiled: May 13, 2020Publication date: August 4, 2022Applicant: XMOS LTDInventor: Douglas Roger PULLEY

Publication number: 20210016340Abstract: A safety device with efficiency and utility value, for manipulating small pieces of metal plate to be punched or otherwise worked by an industrial power press equipped with fixtures for punching machines or other purposes. The stock is held magnetically to a non-magnetic plate in which magnets are embedded. The design and concept may be used for both repeated random punches as well as repeated punch patterns. The magnets surround a relatively small hole through which the punch is made. The plate bridges the distance between the contact points of the industrial punch's stripper so that the punch tool may be easily and safely extracted. The plate also extends outward, toward the operator, to provide a safe hand-hold distance from all points of operation and pinch points. Also provided are punch explosion shields for additional protection. The device also adds mass to an otherwise tenuous and fragile work piece for the purposes of accurate placement and positional anchoring.Type: ApplicationFiled: June 26, 2020Publication date: January 21, 2021Inventors: William Douglas Rogers, Richard D.

Patent number: 10753736Abstract: In one embodiment, a method comprises generating, by a computing device from first and second images of a projected pattern of laser dots detected by respective camera devices in a physical environment, a stereoscopic two-dimensional (2D) object pair based on determining 2D positions for each of the laser dots detected in the first and second images, creating a first mesh of geometric patterns from the 2D positions in the first image and a corresponding second mesh of the geometric patterns from the 2D positions in the second image, and creating the stereoscopic 2D object pair based on matching corresponding geometric patterns from the first and second meshes of the geometric patterns. A three-dimensional model (3D) of the physical environment is generated based on executing stereoscopic triangulation of the stereoscopic 2D object pair. The 3D model causes a controllable device to interact with the physical environment.Type: GrantFiled: July 26, 2018Date of Patent: August 25, 2020Assignee: CISCO TECHNOLOGY, INC.Inventors: Khanh Vinh Nguyen, Douglas Roger Banks, Naveen Kumar Tyagi

Patent number: 9928643Abstract: Embodiments use hierarchical continuous level of detail (H-CLOD) trees with inherited splitting plane partitioning to reduce visual artifacts in renderings. For example, a three-dimensional mesh can be iteratively split, according to iteratively defined splitting planes, until sub-meshes are smaller than a predetermined bucket size. Each splitting can define a hierarchical level of a tree, so that the original mesh is a root node, each split sub-mesh is a child node, and the smallest meshes are leaf nodes. An H-CLOD tree can be generated by simplifying and combining each group of sibling node sub-meshes bottom-up into a simplified parent mesh accounting for inherited splitting planes, so that the tree has a most simplified mesh as its root node and a most un-simplified mesh formed by a combination of its leaf nodes. At render time, traversing the H-CLOD tree can produce a desired level of detail from the pre-computed nodes.Type: GrantFiled: January 5, 2016Date of Patent: March 27, 2018Inventor: Douglas Rogers

Patent number: 7349497Abstract: A receiver circuit is for processing a received signal which includes at least a first portion and a second portion which repeats the content of the first portion after a repeat interval. For example, the receiver may be for DVB-T signals using COFDM. In order to ensure that the estimated symbol start position is accurate, the receiver calculates two correlation values, namely an early correlation and a late correlation. The early correlation is measured between samples ahead of an assumed first portion start position and ahead of an assumed second portion start position, and the late correlation is measured between samples behind an assumed first portion end position and behind an assumed second portion end position. When the assumed start and end positions are accurate, the early and late correlations are equal, and so the assumed start and end positions are controlled to equalize the early correlation and the late correlation.Type: GrantFiled: July 18, 2000Date of Patent: March 25, 2008Assignee: Conexant Systems, Inc.Inventors: Douglas Roger Pulley, Thomas Foxcroft
