Patent number: 11907448Abstract: A method includes receiving sensor data from one or more sensors that corresponds to a location of a stylus device and determining that a tip of the stylus device is in contact with a physical surface based on the sensor data. While in contact, the method includes determining a new location of the tip of the stylus device based on the location data, mitigating a tracking error of the determined new location of the tip of the stylus device by translating the new location from a 3D space domain to a 2D space domain that corresponds to the physical surface and adjusting the new location based on a comparison of the new location and historical locations. The stylus device can further ascertain surface characteristics through sensor data and simulate surface characteristics via haptic feedback effects.Type: GrantFiled: April 14, 2023Date of Patent: February 20, 2024Assignee: Logitech Europe S.A.Inventors: Mario Gutierrez, Philip Waldron, Fabien Zellweger, Damien O'Sullivan

Patent number: 11221730Abstract: In some embodiments, an input device for interfacing within an VR/AR environment can include a processor, one or more motion tracking sensors to track a motion of the input device in three-dimensional (3D) space, where a cursor in the VR/AR environment moves based on the tracked motion of the input device in 3D space and is limited to tracked motion having three degrees of freedom (DOF). The input device can further include a button that, when activated, selects an application window in the VR/AR environment when the cursor is placed over the application window, where the application window moves in the VR/AR environment based on the tracked motion of the input device in 3D space while the application window is selected. The input device can include a user interface that, when activated, accesses and controls content on the selected application window.Type: GrantFiled: September 15, 2020Date of Patent: January 11, 2022Assignee: Logitech Europe S.A.Inventors: Padraig Murphy, Andreas Connellan, Olivier Riviere, Fergal Corcoran, Pierce O'Bradaigh, Jan Findlater, Philip Waldron, Gavin McGlynn, Denis O'Keeffe, Jerry Ahern, Marcel Twohig

Patent number: 8796012Abstract: A technique for high sensitivity evanescent field molecular sensing employs a detection scheme that simultaneously couples a polarized beam to a single mode of a waveguide, and couples the polarized beam out of the waveguide to specularly reflect the beam by the same grating. Strong interaction with the single (preferably TM) mode is provided by using a silicon on insulator (SOI) wafer having a waveguide thickness chosen between 10-400 nm so that the majority of the mode field strength spans the evanescent field. Well known, robust techniques for producing a grating on the waveguide are provided. Interrogation from a backside of the SOI wafer is taught.Type: GrantFiled: December 2, 2009Date of Patent: August 5, 2014Assignee: National Research Council of CanadaInventors: Bill Sinclair, Jens Schmid, Philip Waldron, Dan-Xia Xu, Adam Densmore, Trevor Mischki, Greg Lopinski, Jean Lapointe, Daniel Poitras, Siegfried Janz

Patent number: 7698477Abstract: A method and apparatus is provided wherein a central Credit Controller Entity (CCE) is connected to a PCIE fabric environment by means of several buses. Flow Control information sent to the CCE over two of the buses indicates the buffer storage capacity that is available at respective Receiver components in the PCIE fabric. The CCE processes the Flow Control information, to generate updates that are sent by a third bus to Transmitter components corresponding to the Receivers. In one useful embodiment, directed to a method of Flow Control management, the CCE provides a repository adapted to store credit count information that represents the available storage capacity of respective Receivers. The method further comprises routing further credit count information from a given Receiver to the CCE, for storage in the repository, following each of successive events that affect the storage capacity of the given Receiver.Type: GrantFiled: November 30, 2005Date of Patent: April 13, 2010Assignee: LSI CorporationInventors: Jeffrey William Breti, Douglas Elliott Sanders, Harish Bharadwaj, Suparna Behera, Gordon Douglas Boyd, Richard John Bombard, Philip Waldron Herman, Jr.
