Patent number: 6987474Abstract: A method and apparatus are provided for reducing distortion in a dynamically delayed digital sample stream of an imaging system. The method includes the steps of delta-sigma modulating an input analog signal of the imaging system at a frequency above the Nyquist frequency of the input analog signal to generate a digital sample stream and changing a length of the sample stream to delay a portion of the sample stream while maintaining synchronism between a delta-sigma modulator and a demodulator of the system.Type: GrantFiled: October 26, 2004Date of Patent: January 17, 2006Assignee: Q-Dot, Inc.Inventors: Steven R. Freeman, Matthew O'Donnell, Thomas E. Linnenbrink, Marc A. Morin, Marshall K. Quick, Charles S. Desilets

Patent number: 6377514Abstract: An acoustic/video processing stack of a plurality of substantially identical acoustic/video processing stacks is provided for attachment to a processing stack backplane and which together generate a VGA signal for display of a three-dimensional acoustic image. The acoustic/video processing stack includes a two-dimensional array of transducer elements, a companion chip block coupled to and adapted to transceive acoustic signals under a time-division multiplexed format through the transducer elements and to provide a portion of the VGA signal together generated by the plurality of acoustic/video processing stacks and a backing block disposed between the two-dimensional array and companion chip block and adapted to acoustically isolate the two-dimensional transducer array from the companion chip block, said companion chip block and backing block being of a size and diameter substantially the same as the two-dimensional transducer array.Type: GrantFiled: April 6, 2000Date of Patent: April 23, 2002Assignee: Q-Dot, Inc.Inventors: Thomas E. Linnenbrink, Charles S. Desilets, Marshall K. Quick, Thomas K. Bohley, Timothy G. O'Shaughnessy, Lyle E. Whelchel, R. Carver Anderson

Patent number: 4734582Abstract: A novel readout circuit for a charge injection device is disclosed permitting selection of the integration time to optimize performance. A primary application of the invention is to IR sensing in which performance is required at both low and very high levels of radiation. The readout circuit, in one practical configuration, utilizes a dump pulse recurring at the interval required to scan all elements, in advance of the read pulse also recurring at the scanning interval. The integration time may be adjusted in multiples of the readout period for a single element up to the frame scanning interval, or in approximate fractions of the readout period for a single element, or, at the limit, in a fraction of a microsecond.Type: GrantFiled: December 4, 1986Date of Patent: March 29, 1988Assignee: General Electric CompanyInventors: Martin D. Gibbons, Samuel C. Wang, Kenneth J. Fuhr, Marshall K. Quick

Patent number: 4361891Abstract: A PN sequence signal estimator is described which synergistically co-operates with an adaptive array processor and a spread spectrum communication system modem such that the adaptive array will null interfering signals, but not desired signals. This is accomplished with the signal estimator generating an estimate of the desired coded signal through the use of the local code and the detected correlation in the modem, and feeding the estimate back to the array in such a manner that it subtracts from the array error voltage, thereby inhibiting null formation.Type: GrantFiled: December 22, 1980Date of Patent: November 30, 1982Assignee: General Electric CompanyInventors: Helmut Lobenstein, Marshall K. Quick

Patent number: 4288858Abstract: A processor capable of performing a two-dimensional inverse transform on high speed analog data and outputing the results in a display compatible format. The processor utilizes two charge coupled devices (CCD's), two matrix multipliers, which each perform a one-dimensional transform. The one-dimensional transformed data is multiplexed into a series to parallel converter so that another matrix multiplier can complete the two-dimensional transformation of the analog data.Type: GrantFiled: October 1, 1979Date of Patent: September 8, 1981Assignee: General Electric CompanyInventors: Pasquale A. Merola, Marshall K. Quick
