Patent number: 8135564Abstract: A signal filtering technique is designed to remove the effects of a periodic, low-frequency noise signal from a signal of interest. A signal waveform is sampled at different points of a number of consecutive periodic noise signal cycles and the collected samples are averaged to produce a corrected signal. The number of consecutive cycles in which samples are taken and averaged is inversely related to the signal amplitude such that as the signal level decreases, the number of cycles examined increases. The technique is particularly applicable to periodic signals associated with the output of Hall effect sensors in an electrical metrology environment. Improved RMS calculations are obtained for filtering low-frequency random noise from Hall sensors by averaging samples at different points of a signal cycle to create a composite desired signal cycle to facilitate other signal calculations.Type: GrantFiled: February 10, 2011Date of Patent: March 13, 2012Assignee: Itron, Inc.Inventors: Michel Gervais, Michael E.

The intakes and restrictor are sized and positioned such that the ratio between: the conductance of the path from the inlet to the greater demand sensor to the conductance of the path between the sensors effectively isolates the lesser demand sensor from the effects of the greater demand sensor.Type: GrantFiled: September 26, 2006Date of Patent: May 10, 2011Assignee: Science Applications International CorporationInventors: Steven Gerald Haupt, James Ha, David Rose

Patent number: 7885743Abstract: An electric mirror control device provided with a proportionality constant conversion means for converting the proportionality constant of a detection output voltage to the angle of a mirror surface to be positive or negative. When an up-down sensor and a right-left sensor for detecting the angle of the mirror surface have a plurality of specifications, each of which has a different proportionality constant of the detection output voltage to the angle of the mirror surface, controller determines the specification of the angle sensors based on whether the proportionality constant of the detection output voltage output via the proportionality constant conversion means is positive or negative, and controls an up-down motor or a right-left motor in accordance with the determined specification stored in advance.Type: GrantFiled: May 1, 2008Date of Patent: February 8, 2011Assignee: Honda Motor Co., Ltd.Inventors: Yoshiki Noro, Kenji Shioiri

Patent number: 7844414Abstract: A method of calibrating an individual sensor of a particular sensor type whose output varies non-linearly with at least one measured quantity and at least one operating condition. The first step includes producing a set of calibration curves for each sample sensor of the particular sensor type. The resulting sets of calibration curves are then averaged and the results used to produce a generic calibration surface for the particular sensor type showing its variation. Individual calibration measurements are then taken for a number of different values of the measured quantity at a small number of discrete values. The individual calibration readings are then used to map the generic calibration surface to the individual calibration measurements of the individual sensor.Type: GrantFiled: December 4, 2008Date of Patent: November 30, 2010Assignee: Transense Technologies PLCInventor: Victor Alexandrovich Kalinin

Patent number: 7783404Abstract: Calibration of an FNR lever, wherein signal outputs as the FNR lever is transitioned to and from the neutral position and through a range of positions, are determined. It is then determined whether the values are within expected norms. If not, a fault condition exists. The operator is also prompted to input acknowledgments when the FNR lever is at the fully rearward and forward positions. Signal values outputted by a neutral switch are sensed when the lever is initially moved to the neutral position, and at a predetermined time thereafter, to test a propulsion enable or latch relay which is to provide a predetermined output for a predetermined time after the lever moves into the neutral position, for transitioning of the system to neutral operation.Type: GrantFiled: July 17, 2006Date of Patent: August 24, 2010Assignee: CNH America LLCInventors: Robert L.

Patent number: 7706995Abstract: Systems, methods, and apparatus, including software implementation, are disclosed providing drift prediction of output values for manometers. A signal or other indication may be provided for or in relation to a capacitance manometer when a servicing, replacing, and/or zeroing event is predicted or determined to be required, based on a history (e.g., timestamps) associated with previous zeroing events. Previously recorded timestamps can be curve fit with suitable functions to calculate or predict future maintenance, calibration, and/or replacement events for a manometer. Such signals or indications can be generated as an on-screen indication, and could also be available upon interrogation of the manometer via a digital communications link or system.Type: GrantFiled: April 16, 2007Date of Patent: April 27, 2010Inventors: Philip Sullivan, David Alcaide

Patent number: 7698082Abstract: First and second inertial instruments have parallel sense axes and produce respective first and second output signals using associated first and second scale factors. Bias errors are estimated using the change in state of sign of the first and second scale factors. A substitute scale factor is determined to be an equivalent of the second scale factor and is based on the first scale factor and a difference between the first and second scale factors. Errors in the second scale factor are calculated based on the first scale factor and the substitute scale factor where a sign of one of first and second scale factors changes going from the first time interval to the succeeding time intervals. First and second corrected output signals are generated based on the respective first and second output signals and correction of the second scale factor error.Type: GrantFiled: May 20, 2008Date of Patent: April 13, 2010Assignee: Northrop Grumman Guidance and Electronics Company, Inc.Inventor: Charles A.

Patent number: 7668617Abstract: The invention relates to a method of calibrating an ophthalmic-lens-piercing machine, a device used to implement one such method and a ophthalmic-lens-machining apparatus comprising one such device. The inventive method applies to a machine including a piercing tool, a lens support which is associated with a first reference mark (O1, X1, Y1), and programmable tool-control means which are associated with a second reference mark expressing set co-ordinates which define a target piercing point (M). A template is placed on the support, and the template includes pre-applied markings defining a third reference mark (O3, X3, Y3), such that the third reference mark in essentially in line with the first reference mark. The template is pierced at a pre-determined point corresponding to a target point, and an image of the template this point position, and a correction is applied to the set co-ordinates that can compensate for the misalignment.Type: GrantFiled: September 6, 2004Date of Patent: February 23, 2010Assignee: Briot InternationalInventors: Michaël Vassard, Jean-Jacques Videcoq
