Patent number: 11860080Abstract: In some examples, a system including a fluid stream monitoring system. The monitoring system includes an illumination device configured to illuminate at least some of particles suspended in a fluid stream; and an imaging device configured to image the illuminated particles at a first image plane that intersects a longitudinal axis of the fluid stream, wherein the illumination device and the imaging device are registered to the fluid stream delivery device in the first image plane, where the first image plane is substantially orthogonal to the longitudinal axis. The system includes processing circuitry configured to determine one or more physical characteristics of the fluid particles.Type: GrantFiled: December 29, 2021Date of Patent: January 2, 2024Assignees: Rolls-Royce Corporation, Rolls-Royce plcInventors: Scott Nelson, Taylor K.

Patent number: 8147129Abstract: An apparatus for use with automatic testing equipment for testing infrared sensors on integrated circuits is provided. The apparatus includes an infrared source, a heat mass, and an electronic frequency modulator. The infrared source is modulated according to a predetermined test frequency such that the infrared source emits an infrared test signal representative of a test temperature and corresponding to the temperature of the heat mass and the predetermined test frequency. A signal processor, electrically coupled to an integrated circuit having an infrared sensor, receives a sensed signal from the infrared sensor in response to the infrared test signal and uses the sensed signal according to the predetermined test frequency to determine a measured temperature.Type: GrantFiled: April 8, 2009Date of Patent: April 3, 2012Assignee: Analog Devices, Inc.Inventors: John Grubb, Gerard Blaney, Eamon Culhane

Patent number: 8105009Abstract: A method of positioning lumber in a given orientation in a handling apparatus having a base frame, a longitudinal transport assembly, and at least two gripper arm support platforms with a pair of gripper arms positioned on each of the support platforms. A work piece is gripped with the gripper arms without the work piece engaging the longitudinal transport assembly. The gripper arms are adjusted on at least one of the support platforms in a direction generally perpendicular to the longitudinal transport assembly in order to selectively position the work piece. The work piece is then brought into engagement with the transport assembly and the gripper arms are released from the work piece.Type: GrantFiled: May 8, 2008Date of Patent: January 31, 2012Assignee: WPS Industries, Inc.Inventors: Jeff Harper, Wayne Parks, Jeremy S. Clark, Anthony G. Clark, Clyde Stearns, Mark Burns, Brian Wallace Smith, John Grubbs, Donald Haley

Publication number: 20050017450Abstract: A game piece and method of game playing is disclosed wherein individual game pieces include a multi-piece base with scoring indicia printed on a top portion. The top is rotatable with respect to a bottom portion. A slotted aperture in the top reveals data that varies as the top portion is rotated with respect to the bottom. The variable numbers indicate capability characteristics of the particular game piece. In addition, the base includes slots for the addition of items that enhance the capabilities of the individual game piece. A plurality of additional items fit in the slots with each additional item affecting the numeric values of that character. The items may be dropped or picked up during the game thus permitting customization of each game piece as well as the ability to dynamically alter the characteristics of each game piece.Type: ApplicationFiled: July 23, 2003Publication date: January 27, 2005Applicant: WizKids LLCInventors: Jordan Weisman, James Long, Scott Hungerford, Matthew Robinson, John Grubb, Ethan Pasternack
