Patent number: 9211695Abstract: A monitoring device includes a light source, an optical filter, and an optical detector. The monitoring device may monitor curing processes, such as ultraviolet (UV) curing processes to determine the progression of the level of cure of a light-activated material to a substrate. The light source emits light toward a light-activated material, such as a film, and/or a substrate. The optical filter is positioned so that a wavelength of the light is transmitted through the optical filter after the light is reflected off of the substrate and/or the film. The optical detector is positioned to detect the light that is transmitted through the optical filter.Type: GrantFiled: May 15, 2012Date of Patent: December 15, 2015Assignee: Palo Alto Research Center IncorporatedInventor: Christopher Paulson

Patent number: 9070289Abstract: A method and system for measurement of ground based vehicle speed includes a movable platform that includes an unmanned aerial vehicle (UAV) located in proximity to a roadway, the UAV operates under control and navigation of a UAV control unit, and the UAV also carries camera and monitoring equipment, the camera and monitoring equipment including an onboard computing system, and a camera with a wide angle lens and a camera with a telephoto lens, the cameras being mounted on a pan/tilt device. An algorithm operated by the on-board computing system is used to detect and track vehicles moving on a roadway. The algorithm is configured to detect and track the vehicles despite motion created by movement of the UAV. The cameras mounted on the pan/tilt device are moved under the direction of the computer vision algorithm to maintain a target vehicle of the detected moving vehicles in view, and the speed of the target vehicle is measured.Type: GrantFiled: May 10, 2013Date of Patent: June 30, 2015Assignee: Palo Alto Research IncorporatedInventors: Eric Saund, Christopher Paulson, Gregory Burton, Eric Peeters

Patent number: 9022515Abstract: A measurement device for measuring a response to actuation of an electro-mechanical transducer in a print head assembly for an inkjet printing system includes a sensing circuit and a measurement circuit. The sensing circuit provides a path to system ground for the transducer. The transducer is associated with an ink chamber in the print head assembly. The transducer is configured to transfer energy to contents of the chamber in response to an actuation of the transducer in conjunction with electronics controller and waveform amplifier modules of the printing system. The measurement circuit monitors a ground signal at a transducer-side of the sensing circuit and a reference signal at a system ground-side of the sensing circuit. The measurement circuit generates a difference signal indicative of a difference between the ground and reference signals. Various embodiments of methods for measuring the response and additional embodiments of devices are provided.Type: GrantFiled: March 13, 2013Date of Patent: May 5, 2015Assignee: Palo Alto Research Center IncorporatedInventors: Steven E.

Patent number: 9004669Abstract: Methods of leveling ink on substrates and apparatuses useful in printing are provided. An exemplary embodiment of the methods includes irradiating ink disposed on a surface of a porous substrate with radiation emitted by at least one radiant energy source. The radiation heats the ink to at least a viscosity threshold temperature of the ink to allow the ink to flow laterally on the surface to produce leveling of the ink. The ink is heated sufficiently rapidly that heat transfer from the ink to the substrate is sufficiently small during the leveling that ink at the substrate interface is cooled to a temperature below the viscosity threshold temperature thereby preventing any significant ink permeation into the substrate.Type: GrantFiled: September 26, 2013Date of Patent: April 14, 2015Assignees: Xerox Corporation, Palo Alto Research Center IncorporatedInventors: Gregory J. Kovacs, Steven E. Ready, David K. Biegelsen, Lars E. Swartz, Christopher Paulson
