Patent number: 11113919Abstract: An optical device includes an array of lenses and a plurality of first and second segments disposed under the array of lenses. At a first viewing angle, the array of lenses presents a first image for viewing without presenting the second image for viewing, and at a second viewing angle different from the first viewing angle, the array of lenses presents for viewing the second image without presenting the first image for viewing. In some examples, individual ones of the first and second segments can comprise specular reflecting, transparent, diffusely reflecting, and/or diffusely transmissive features. In some examples, individual ones of the first and second segments can comprise transparent and non-transparent regions. Some examples can incorporate more than one region producing an optical effect.Type: GrantFiled: August 20, 2018Date of Patent: September 7, 2021Assignee: WAVEFRONT TECHNOLOGY, INC.Inventors: Christopher Chapman Rich, Joel Mikael Petersen, Roger Winston Phillips, John Michael Tamkin

Publication number: 20210271105Abstract: In certain embodiments, a master for fabricating an optical product is disclosed. For example, the optical product can be configured to be an anti-counterfeit feature such as a patch, a window, or a thread on a banknote. The optical product can be configured, when illuminated, to reproduce by reflected or refracted light, a 3D image of at least a part of a 3D object. The master can include a first surface and a second surface opposite the first surface. The second surface can include a plurality of portions. Each portion can correspond to a point on a surface of the 3D object. Each portion can include features corresponding to non-holographic elements on the optical product. A gradient in the features can correlate to an inclination of the surface of the 3D object at the corresponding point. An orientation of the features can correlate to an orientation of the surface of the 3D object at the corresponding point.Type: ApplicationFiled: October 15, 2020Publication date: September 2, 2021Inventors: Christopher Chapman Rich, Phillip Christopher Harvey, Joel Mikael Petersen

Patent number: 9942106Abstract: A network broker divides IP address space into subnets to allow IT infrastructure transfers using a cloud computing environment. A link established between a client and network broker allows transfer of data and provides connectivity between the client and cloud providers. IT infrastructure to be divested is provisioned onto subnets in a cloud environment. A second link is established via the network broker between the entity being divested and the provisioned IT infrastructure. Client access to provisioned IT infrastructure is cut by rerouting, at the network broker, traffic destined to the subnet(s) hosting the provisioned IT infrastructure from the link to the second link. After a new owner assimilates the divested IT infrastructure using the second link, network broker routing rules are adjusted to sever access of the new owner to the subnet(s) hosting the divested IT infrastructure and return access to the subnet(s) to the client.Type: GrantFiled: March 15, 2013Date of Patent: April 10, 2018Assignee: ACCENTURE GLOBAL SERVICES LIMITEDInventors: Christopher Chapman, Zahra S.

Patent number: 9851070Abstract: Implementations disclosed herein include optical sheets comprising one or more regions including one or more optical elements. Each of the one or more optical elements includes a plurality of microstructures. The one or more optical elements can be configured to tailor the radiation pattern output from a source of illumination. The one or more optical element can be further configured to impart a visual appearance to the optical sheet that is different from a standard lenticular or prismatic sheet. In various implementations, the one or more regions can be demarcated from each other or the surrounding by borders. The borders of the one or more regions can be configured to form one or more letters, one or more symbols or logos for identification and/or security purposes. Various implementations of the optical sheet can include nano-particles in addition to the optical elements to enhance the aesthetic quality of the optical film.Type: GrantFiled: September 9, 2014Date of Patent: December 26, 2017Assignee: Wavefront Technology, Inc.Inventors: Christopher Chapman Rich, Phillip Christopher Harvey, Eric William Hearn Teather, Joel Mikael Petersen

Patent number: 9777937Abstract: A controller and loop performance monitoring system is coupled to a controller, detects loop performance degradation in time, and diagnoses a cause of the loop performance degradation. If the cause of loop performance degradation is poor controller tuning, a re-tuning mechanism is triggered. If the cause of loop performance degradation is external to the controller (a disturbance acting on the loop, hardware malfunction etc.), an action defined in control strategy is taken, or the user is informed via alarm, user interface, or upper layer software that collects the performance measures. The monitoring itself is designed to be recursive and with low memory demands, so it can be implemented directly in the controller, without need for data transfer and storage. The monitoring is modular, consisting of oscillation detection and diagnosis part, performance indices part, internal logic part, and triggering part, easily extensible by other performance indices or parts (e.g. for overshoot monitoring).Type: GrantFiled: April 22, 2014Date of Patent: October 3, 2017Assignee: Honeywell International Inc.Inventors: Petr Endel, Rajni Jain, Christopher Chapman, Ranganathan Srinivasan

Patent number: 9507889Abstract: Analysis of a seismic event, such as a microseismic event caused by hydraulic fracturing, comprises measuring seismic waves emitted by the event and converting the measurements into two values for magnitude of explosion or implosion and for magnitude of displacement discontinuity at a plane, together with two directions, a direction of a normal to the plane and a direction of displacement; where the two values and the two directions compose the moment tensor describing the seismic event. The measurements may be converted into the moment tensor and decomposed into the values and directions. The values and directions associated with several seismic events may be displayed concurrently on a graphic display as a graphic representation of multiple events, where each event may be depicted with magnitude of expansion or contraction represented by a volume and the plane represented as a laminar object.Type: GrantFiled: October 6, 2011Date of Patent: November 29, 2016Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Christopher Chapman, Walter Scott Leaney, Adrian Alexander
