Patent number: 7564626Abstract: Two stereo images are created by splitting a single image into two images using a field of view dividing splitter. The two images can be displayed side by side so that they can be viewed directly using stereopticon technology, heads-up display, or other 3-D display technology, or they can be separated for individual eye viewing. The two images focus on one imager such that the right image appears on the right side of the monitor and the left image appears on the left side of the monitor. The view of the images is aimed to converge at a given object distance such that the views overlap 100% at the object distance. Measurement is done with at least one onscreen cursor.Type: GrantFiled: December 18, 2006Date of Patent: July 21, 2009Assignee: GE Inspection Technologies LPInventors: Clark A. Bendall, Raymond Lia, Jon R. Salvati, Theodore A. Chilek

Electrical adapter for medical diagnostic instruments using replaceable LEDs as illumination sources
Patent number: 7458934Abstract: An LED for use with a medical diagnostic instrument having an adapter disposed between an instrument head and a hand-grippable handle, the LED being removably attachable in relation to the adapter in order to permit selective replacement of the LED, as needed. The LED is situated in order to provide mechanical and electrical interface with at least one of the adapter and the instrument, thereby enabling the adapter and the LED to convert the illumination source of the instrument selectively between an incandescent light source and the LED. The adapter matches a polarity between the LED and a power supply that is specifically intended for powering an incandescent light source.Type: GrantFiled: May 17, 2007Date of Patent: December 2, 2008Assignee: Welch Allyn, Inc.Inventors: Chris R.

Patent number: 7262797Abstract: A system and method for storing, within an image transfer medium, an image and image-specific data associated with the image includes obtaining the image-specific data from a probe such as a borescope or endoscope, obtaining the corresponding image, choosing a specific image transfer medium, writing the image to the medium, and writing the image-specific data to a marker in the medium. In this manner, storing a combination of image data and one or more of system calibration data, overlay replacement data, and audio comment data in a single file of either a non-standard file format or a standard file format that does not explicitly support the inclusion of these data types is possible.Type: GrantFiled: May 25, 2004Date of Patent: August 28, 2007Assignee: GE Inspection Technologies LPInventors: David L.

Publication number: 20040183900Abstract: The system automatically performs analysis on images from a remote video inspection apparatus to provide an operator with an indication of areas that are potentially out of specification, or which require more detailed analysis by the operator. Pattern recognition algorithms are applied to sequential images to search for anomalies or defects in the images. The search area is initially limited to edges of the item being inspected where the probability of defects is much higher. To reduce the processing requirements and probability of false detection, the search area is narrowed to a limited field of view and depth. Defects such as dents and small cracks are detected using stereo measurement techniques or by projecting a known supplementary image into the defect. These techniques are used to provide an image disparity map. Using known triangulation algorithms, this map provides depth and distance information to the processing system.Type: ApplicationFiled: March 20, 2003Publication date: September 23, 2004Applicant: Everest VITInventors: Thomas Karpen, Clark Bendall, Jon R.

Patent number: 6147705Abstract: A video colposcope includes a system microcomputer having algorithms for color balance levels stored into memory. A video camera obtains a subject electronic image of a subject object, and using algorithm-driven digital signal processing circuitry (DSP), color saturation, hue, and intensity levels of the subject electronic image are modified according to DSP reference filter algorithm and reference color balance levels as stored, thus producing a modified electronic image corresponding to the subject electronic image. The modified electronic image is outputted to a display in continuous real time as the corresponding subject image is obtained by the video camera. This modified electronic image emulates that obtained through an optical green filter and incorporates a simulated white balance.Type: GrantFiled: August 20, 1996Date of Patent: November 14, 2000Assignee: Welch Allyn Inc.Inventors: Allan I.

Patent number: 6097848Abstract: A video signal processor includes an edge enhancement determining circuit that senses the amount of some characteristic of that signal which provides a measure of noise inherent in the signal, precisely determines a preferred amount of edge enhancement to be applied to a video signal as a function of that characteristic, and applies that amount of edge enhancement to the video signal. The video signal characteristic, used to determine the noise content of the video signal includes the amount of automatic gain control amplification and the brightness of the viewed scene. Thus, the amount of edge enhancement added to the video signal is adaptively controlled according to the brightness level of the viewed scene and the amplification level of the video signal by the automatic gain control circuit, and provides the proper amount of edge sharpness to the viewed video scene as a function of its noise content.Type: GrantFiled: November 3, 1997Date of Patent: August 1, 2000Assignee: Welch Allyn, Inc.Inventor: Jon R.

Patent number: 6025829Abstract: An image generator generates brightness modulated bars for a video monitor. The bars run parallel to the scan line of the monitor allowing the use of a relatively slow digital to analog converter (DAC). A frame buffer need only be as deep as a number of different shades desired on a particular scan line, instead of needing to be as deep as the resolution of the DAC. Using a multiplexer allows use of a 1 bit deep frame buffer instead of a conventional 12 bit deep frame buffer. A feature of the image generator allows efficient determination of a mean gray scale used in generating the brightness modulated bars. The brightness modulation scheme is sinusoidal, that is, based on a sine function, for specified applications but can be any other modulation scheme based on, for example, a sawtooth function, a step function, an exponential function, and so forth.Type: GrantFiled: October 28, 1996Date of Patent: February 15, 2000Assignee: Welch Allyn, Inc.Inventors: Paul DeLucia, Arthur G.
