| 20090321249 | Method of Hard Coating a Blade - A sputtering apparatus includes a chamber for containing a feed gas. An anode is positioned inside the chamber. A cathode assembly comprising target material is positioned adjacent to an anode inside the chamber. A magnet is positioned adjacent to cathode assembly. A platen that supports a substrate is positioned adjacent to the cathode assembly. An output of the power supply is electrically connected to the cathode assembly. The power supply generates a plurality of voltage pulse trains comprising at least a first and a second voltage pulse train. The first voltage pulse train generates a first discharge from the feed gas that causes sputtering of a first layer of target material having properties that are determined by at least one of a peak amplitude, a rise time, and a duration of pulses in the first voltage pulse train. The second voltage pulse train generates a second discharge from the feed gas that causes sputtering of a second layer of target material having properties that are determined by at least one of a peak amplitude, a rise time, and a duration of pulses in the second voltage pulse train. | 12-31-2009 |

| 20090051578 | Method and System for Correcting Switched Input A/D Converters - A system is described for correcting a switched input A/D converter circuit that performs a plurality of A/D conversions. The system includes an oversampling circuit, a switched input controller, separation circuitry, and a signal processing subsystem. The oversampling circuit is configured to convert one or more input analog signals into oversampled output signals. The switched input controller is configured to switch a separate calibration signal into the oversampling circuit, as a replacement for the input analog signal, for at least some of the A/D conversions. The separation circuitry is configured to separate the oversampled output signal from the calibration signal. The signal processing subsystem is configured to synchronously and separately process the oversampled output signal and the calibration signal so as to substantially reduce unwanted correlated response of the switched input A/D converter circuit. | 02-26-2009 |

| 20090232348 | Image Object Separation - Techniques and systems for segmenting one or more objects in a subject image resulting from subjecting one or more objects to imaging using an imaging apparatus are disclosed, such that limitations of image noise, object proximity, image intensity variations, shape complexity, and/or computational resources may be mitigated. Merely border edges of objects in a subject image can be generated, for example, by using edge detection and discarding interior edges. Geometric difference values of the identified boundaries of the objects in the subject image can be calculated. One or more transitions between objects can be identified by using the geometric difference values, for example, which may result in data that represents a location in the image of an object to be segmented. | 09-17-2009 |
| 20110033118 | EDGE DETECTION - One or more techniques and/or systems for detecting edges in images of objects subjected to imaging using imaging apparatus are disclosed, such that the effect of image noise on the edge detection can be mitigated. Ratios of intensity values (e.g., signal values) for a subject region (e.g., a pixel) and respective adjacent regions are determined. An adaptive threshold value is determined for respective adjacent region pairs. The ratio value is compared to the adaptive threshold value for respective adjacent region pairs, to determine whether an edge is present between the respective adjacent region pairs. | 02-10-2011 |
| 20110085695 | IMAGE COMBINING - One or more techniques and/or systems for combining images of objects are disclosed where an image of a first object is to be inserted into an image of a second object in such a manner as to make the insertion substantially undetectable by a human observer of the combined image. An object generator generates a substantially artifact free image of a first object. An object locator orients the first object image according to a desired insertion point in a second object image. A forward projector converts the first object image into projection space data of the first object, and a combiner combines the first object projection space data with the second object projection space data. The combined projection space data is converted to image space data by a reconstructor, and the resulting combined image space data can be displayed on a monitor for human observation. | 04-14-2011 |

| 20100311181 | Assay Reader Insert and Method of Maintaining a Reader - An assay reader system incorporating a conventional assay reader, for example a lateral flow reader, and an insert aligned with the reader's sensor to detect an assay result. The insert may include a housing which defines a cavity to receive a removable barrier, wherein the removable barrier can be aligned between the sensor and the test strip. The barrier may include an optical window, and may be cleanable and/or disposable to maintain the accuracy of the reader. Test strips are introduced into the reader through a receiving port within the insert's housing. An air inlet on the insert further maintains the reader's accuracy by allowing air to be tunneled over the housing to remove excess dust, debris, or the like. | 12-09-2010 |
