Patent number: 6916290Abstract: An in situ breast tumor temperature profile measuring probe includes a rod, thermal sensors and electrical output leads. The thermal sensors are formed in spaced apart holes in an outer insulating layer of the rod and a common electrical input lead to provide an electrical input signal to the thermal sensors is disposed below and has portions exposed at the holes and electrically connected to the thermal sensors. The thermal sensors receive the electrical input signal from the common electrical input lead, sense the temperature of biological matter adjacent to the thermal sensors and produce an electrical output signal correlated thereto. Each electrical output lead mounted to the outer insulating layer is in electrical contact with a different one of the thermal sensors to receive the electrical output signal from the one thermal sensor and output the same.Type: GrantFiled: March 5, 2002Date of Patent: July 12, 2005Assignee: General Electric CompanyInventors: Kristina Helena Valborg Hedengren, William Paul Kornrumpf, Mark Lloyd Miller, Egidijus Edward Uzgiris

Patent number: 6252393Abstract: The invention provides a system and method for normalizing and calibrating a sensor array. The sensor array can comprise differential element sensors, such as for example eddy current sensors, or absolute sensors. A single test specimen is used to normalize and calibrate the sensor array using one or more scans of the test specimen. Notably, only one alignment of the sensor array to the test specimen is required. The test specimen is preferably made of the same or similar type of material as the part to be tested and is of a similar geometric shape that can have a simple flat surface or a more complex surface. A linear feature and several notches are machined into the surface of the specimen by using, for example, electro-discharge machining methods, to provide the necessary signals when scanned by the sensor array. Signals from the linear feature on the test specimen are used to remove any bias and to normalize the dynamic ranges of all of the sensors in the array.Type: GrantFiled: June 10, 1999Date of Patent: June 26, 2001Assignee: General Electric CompanyInventor: Kristina Helena Valborg Hedengren

Patent number: 5822392Abstract: The present invention discloses a multi-resolution detector for use in an x-ray imaging implementation such as computed tomography and digital radiography. The multi-resolution detector includes a two-dimensional, m.times.n element array of low resolution detector elements and at least one high resolution detector element located about the two-dimensional, m.times.n element array of low resolution detector elements. After an object has been completely scanned with the multi-resolution detector the scan data from both the two-dimensional, m.times.n element array of low resolution detector elements and the high resolution detector element is used to reconstruct a high resolution image. In particular, the scan data generated from the two-dimensional, m.times.n element array of low resolution detector elements is used along with the initial scan data generated from the high resolution detector element to iteratively construct a high resolution image of the object.Type: GrantFiled: December 26, 1996Date of Patent: October 13, 1998Assignee: General Electric CompanyInventor: Kristina Helena Valborg Hedengren

Patent number: 5717332Abstract: A system and method for determining fiber-depth of at least one layer of reinforcing fibers within an electrically conductive workpiece is provided. The system comprises an eddy current probe having one or more eddy current elements for generating a respective electrical signal indicative of a spacing with respect to a predetermined section of the reinforcing fibers. A signal processor is connected to the eddy current probe to receive and to process each spacing-indication electrical signal so as to generate data indicative of fiber-depth of the predetermined section relative to a workpiece surface. A display device may be connected to the signal processor to provide visual indicia representative of the fiber depth. Further a controller may be connected to receive and store the fiber-depth data which can be used by a machining device for selectively removing material from the workpiece surface, in accordance with the stored fiber-depth data.Type: GrantFiled: January 23, 1997Date of Patent: February 10, 1998Assignee: General Electric CompanyInventors: Kristina Helena Valborg Hedengren, Richard Oscar McCary

Patent number: 5659248Abstract: An eddy current surface measurement array structure for complete coverage of an underlying inspection surface without requiring mechanical scanning is disclosed. A three-dimensional array of eddy current sense elements is organized as a plurality of layers of two-dimensional sub-arrays. The sub-arrays, although in different layers, are essentially identical in configuration, and are staggered such that the sense elements of one layer provide at least partial coverage of portions of the inspection surface not covered by the sense elements of another layer. As many staggered layers are included as are necessary to ensure that no "blind spots" remain, for complete coverage of the underlying inspection surface. The sense elements are disposed in a layered flexible structure fabricated employing high density interconnect fabrication techniques or other photolithographic techniques.Type: GrantFiled: April 15, 1996Date of Patent: August 19, 1997Assignee: General Electric CompanyInventors: Kristina Helena Valborg Hedengren, William Paul Kornrumpf
