Patent number: 10011121Abstract: An apparatus for printing on cylindrical objects (31) comprises a plurality of printheads (32); and at least one holding device movable relative to the printheads (32) such that, in use, the holding device moves the object between the printheads. The path of the at least one holding device comprises a plurality of vertical sections (34) which are horizontally offset from one another. Each vertical section (34) comprises at least two identically orientated printheads (32) arranged such that they are vertically displaced from one another, with one directly above the others. The at least one holding device moves the object (31) between the at least two printheads (32) such that part or all of its path between the printheads is vertical.Type: GrantFiled: April 28, 2015Date of Patent: July 3, 2018Assignee: TONEJET LIMITEDInventors: Andrew John Clippingdale, John Lawton Sharp, Simon Edwards

Patent number: 9971213Abstract: A frequency controlled electro-optical device includes a substrate having transparent conductive control sections patterned thereon to selectively control the optical state of an electro-optical layer. Each of the control sections are partially electrically isolated from each other by crack lines, which allows for electrical communication between adjacent/proximate control sections to occur. As such, an electrical control signal applied directly to one control section forms an electric field in that control section, and also induces an electrical field in adjacent control sections that are not in direct receipt of the control signal. Therefore, the number of electrical connections required for coupling to a driving circuit to operate the device is minimized, thereby allowing the device to be fabricated with reduced complexity and cost.Type: GrantFiled: June 13, 2016Date of Patent: May 15, 2018Assignee: Kent State UniversityInventors: John Lawton West, Da-Wei Lee, Merrill Groom

Patent number: 9630401Abstract: The invention relates to a method of printing a two-dimensional bit-mapped image having a number of pixels per row, the printhead having a row of ejection channels and each ejection channel having associated ejection electrodes to which voltages are applied in use. During printing, in order to cause volumes of fluid to be ejected from selected ejection channels of the printhead for printing, voltage pulses having values of predetermined amplitude and duration as determined by respective image pixel bit values generated by a raster image processor are applied, at a given pulse period, to the electrodes of the selected ejection channels.Type: GrantFiled: May 19, 2014Date of Patent: April 25, 2017Assignee: Tonejet LimitedInventors: Andrew John Clippingdale, Peter James Brown, Ewan Hendrik Conradie, Ammar Lecheheb, John Lawton Sharp, Robin Timothy Bacon

Patent number: 9427963Abstract: A method of calibrating a printhead, for printing two-dimensional bit-mapped images having a number of pixels per row, is disclosed for printheads (1) having a row of printing channels (5). During printing, in order to cause volumes of charged particulate concentrations of one of a number of predetermined volume sizes to be ejected from selected ejection channels of the printhead to form printed pixels, control pulse values of respective predetermined amplitude and duration, as determined by respective image pixel bit values, are applied to the selected printing channels. The calibration method comprises providing an image (50) that causes each channel of the printhead to be driven with the same pulse value, and printing one or more test prints of the image.Type: GrantFiled: September 17, 2013Date of Patent: August 30, 2016Assignee: Tonejet LimitedInventors: Andrew Clippingdale, Robin Timothy Bacon, Ewan Hendrik Conradie, Ammar Lecheheb, John Lawton Sharp, Jesse David Woolaston

Patent number: 8871133Abstract: Waste reduction, including hazardous waste reduction in photoimaging processes can be accomplished by improving diffusional resolution of cationic curable compositions. The addition of fluorinated polymers including fluorinated surfactants provides improved diffusional resolution in cationic and/or radical based photoimaging formulations allowing for image accuracy improvements, and reduced product and process waste quantity and disposal cost. These fluorinated surfactants also allow for increased cure speed, and non-hazardous constituent formulations that result in less wasted material and time.Type: GrantFiled: March 20, 2012Date of Patent: October 28, 2014Assignee: DSM IP Assets B.V.Inventors: John Lawton, Jigeng Xu, John Southwell, Gordon Smith, Willem D.

Patent number: 8832657Abstract: Systems and methods for objective Deployment Failure risk assessments are provided, which may include fault trees. Systems and methods for the analysis of fault trees are provided as well. The risk assessments system may involve the development of a fault tree, assigning initial values and weights to the events within that fault tree, and the subsequent revision of those values and weights in an iterative fashion, including comparison to historical data. The systems for analysis may involve the assignment of well-ordered values to some events in a fault tree, and then the combination those values through the application of specialized, defined gates. The system may further involve the revision of specific gates by comparison to historical or empirical data.Type: GrantFiled: January 12, 2009Date of Patent: September 9, 2014Assignee: Bank of America CorporationInventors: John Lawton Cowan, Rachel Nemecek

Patent number: 8639476Abstract: A computer-implemented method is provided for generating the estimation of current position, velocity and acceleration state vectors and associated uncertainty estimation (covariance) of a boosting ballistic missile. The method includes constructing a state tensor of the projectile from a plurality of sensor measurements in Earth-Centered, Earth-Fixed (ECEF) coordinates; translating the state tensor to Cartesian coordinates as a transform state; determining a covariance matrix from the transform state; updating the transformed state as an updated transform state; and updating the covariance matrix as an updated covariance. The process can further include adjusting the covariance matrix by an approximate transition matrix and a process noise matrix. The noise matrix can be translated from a local noise matrix based on a propagation time-step, a scaling parameter, and a bias process noise level. A time-of-flight in the state tensor can be updated by smoothing from a launch event.Type: GrantFiled: January 31, 2012Date of Patent: January 28, 2014Assignee: The United States of America as Represented by the Secretary of the NavyInventors: Craig A. Martell, John A. Lawton, David B. Hurley
